I simultaneously traverse countless worlds

"Mo, look at this monstrous monster we've captured!"

When Shinobu Kocho and Kanao Tsuyuri led the two demon captives out of Fujikasane Mountain as if they were cargo, they walked straight into a convoy of more than a dozen trucks and cars. Shinobu Kocho proudly showed off to the demon god Li Mo, jumping up and down and appearing particularly affectionate towards him.

It should be said that Shinobu Kocho's relationship with the demon god Li Mo has made a breakthrough. They quickly went from disliking each other to being inseparable. In addition, Kanae Kocho took special care of her younger sister. Now, Shinobu Kocho is very affectionate towards her man. If it weren't for the fact that Li Mo gave her and Kanae Tsuyuri the task of clearing out Fujikasane Mountain, she would rather stay by Li Mo's side with her sister. For example, as soon as she returned, she ran to Li Mo and took the initiative to ask for credit.

For Kanae Kocho, Shinobu Kocho, and Kanao Tsuyuri, these three beautiful girls are now wholeheartedly devoted to the Demon God Li Mo. Kanae Kocho, for example, follows her man and assists him in his research on demons. As for Fujikasane, a rookie swordsman in the Demon Slayer Corps, his training ground is just a trial given to Shinobu Kocho and Kanao Tsuyuri by the Demon God Li Mo to familiarize them with new fighting styles.

Upon hearing Shinobu's words, the demon god Li Mo, who was studying an ordinary demon, looked up and saw that Shinobu and Kanao Tsuyuri had returned safely. Knowing the two beautiful girls' strength, he stepped forward, affectionately embraced them, and said:

"Yes, Shinobu, you guys did a great job. Let me see..."

Chapter 11 Research on Evil Spirits

As for the reason for his trip to Tengxi Mountain, the ghost god Li Mo naturally had his eye on the dozens of ordinary evil spirits and one alien evil spirit that were rarely gathered there. Otherwise, if it were just a single evil spirit, it wouldn't have made the ghost god Li Mo think about making a trip to Tengxi Mountain.

Don't be fooled by the seemingly random encounters with demons in the anime "Demon Slayer." In reality, those demons only appear for the sake of the plot. When the demon god Li Mo traveled to the present day, he combined the information dictated by Kanae Kocho with the information gathered by his pawns to gather intelligence on the possible existence of demons. He then discovered that demons are not so easy to encounter, and it's even questionable whether Japan has four-figure numbers of demons.

After all, demons need to eat people to survive. Even if they only eat people once every week or two, it would be understandable in the war-torn Warring States period or earlier, as deaths from war and bandits were all too common. However, in modern Japan, how could there be no reaction to the continuous deaths? Naturally, people would start to investigate.

Even if the Demon Slayer Corps tries its best to conceal the existence of demons, and even with the help of Shinto priests from Japan who are married to the Demon Slayer Corps leaders, it's manageable if a few or a dozen people die. But if there are too many demons, leading to too many missing persons and deaths, neither the Demon Slayer Corps nor Shintoism can cover it up. Only a small number of scattered and serious incidents can be barely concealed.

According to the intelligence gathered by the demon god Li Mo, the number of demons in Japan is probably only in the hundreds, or even less than three hundred. Otherwise, the Demon Slayer Corps, with a total of no more than two hundred official swordsmen, would have no way to contain the demons' activities. It would be remarkable if they were not directly eliminated by the demons.

Given Japan's vast land area and tens of millions of people, the demons that number only a few hundred and are difficult to reproduce quickly are relatively hidden. Most of them live in remote towns or hide in big cities and eat people. That's why there are occasional rumors about man-eating monsters. The Japanese government doesn't take these supernatural rumors too seriously. Occasionally, people who actually experience attacks by man-eating demons are recruited by the Demon Slayer Corps and join it, so the impact is suppressed.

It is precisely because such incidents of demons eating people are not frequent, and because the Demon Slayer Corps is working hard to find and eliminate demons, that the existence of man-eating demons in Japan has not been exposed. As for the demon god Li Mo, who wants to study demons in detail, he cannot use his own life essence, which has changed, for research. Therefore, if he wants to find such a rare sample as a demon, he naturally needs to find a suitable place to collect experimental samples.

In this way, the Demon God Li Mo naturally made a trip to Fujikasane Mountain, where the Demon Slayer Corps had spent a lot of effort capturing dozens of demons. With Shinobu Kocho and Kanao Tsuyuri taking action, the Demon God Li Mo gained more than thirty demons for research.

What do you think and feel about the evil spirits that were used for research?

Sorry, neither the ghost Li Mo nor Kocho Kanae cared. Even Kocho Kanae, who was gentle and generous and once wanted to turn evil spirits into humans, had no objection to her man's actions of researching evil spirits. She now put her man's interests first and ignored the fate of those evil spirits.

In any case, in the eyes of normal people, man-eating demons are dangerous creatures, just like man-eating beasts. Kocho Kanae had previously pitied the demons' plight and hoped to see them get rid of their fate of eating people, but that doesn't mean she thought man-eating demons were completely innocent. If it weren't for the fact that the demon god Li Mo had just been tainted by demon blood and turned into a demon, and was just an unlucky guy who encountered bad luck, Kocho Kanae wouldn't have asked the other Pillar-level powerhouses to use him as a precious sample for observation and research.

If Li Mo was originally a man-eating demon, Kanae Kocho might have pitied his fate of becoming a demon, but she might not have been so merciful. The other Pillar-level powerhouses of the Demon Slayer Corps would never have agreed to imprison Li Mo in the basement of the Butterfly Mansion headquarters for research with relatively good treatment. Throwing him directly into Fujisaki Mountain would probably be a low probability event. A clean and swift kill with a single strike would be the most normal outcome.

Currently, none of the evil spirits on Mount Fuji that Guishen Li Mo is researching are innocent. For example, the Hand Demon has eaten dozens of Demon Slayer Corps trainees, and the other evil spirits have all had experience eating people. Naturally, he will not show any mercy when researching them!

………………

In a small open space not far from Fujikasa Mountain, a dozen trucks and several cars formed a temporary camp. Dozens of people coming and going were elite soldiers who had fused with the [Seed of Fusion], and were even specially equipped with firearms for legitimate self-defense.

As for how self-defense is defined, that depends on what Ghost God Li Mo did. Ghost God Li Mo doesn't have any plans to make any big moves in Japan for the time being. The group of bodyguards, servants, and butlers accompanying him are all there to avoid unnecessary trouble. After all, Japan is not a very stable modern society right now. Moreover, even in 21st-century Japan, the security situation is at most relatively peaceful.

—Japan claims to be one of the safest countries in the world in the 21st century. But if you look closely, you'll see how many unsolved cases are never investigated by the Japanese police each year. Even the number of forensic doctors who can perform autopsies is nearly extinct. In addition, yakuza groups are legalized. This shows how much they boast about Japan's safety. At best, it means that there are very few serious crimes. In reality, the darkness behind the scenes is no less. It's just that it's very different from ordinary people's lives. Most people know very little about its inner workings.

In Japan, which had only been a few years after the end of World War I, the country was still in a semi-barbaric stage of development. While this might be manageable in large cities like Tokyo, it was quite common in smaller towns and villages. Local tyrants and Yakuza were rampant, and Li Mo, the "Ghost God," had no intention of playing any face-slapping games with three beautiful girls. With dozens of bodyguards and a convoy accompanying him, he could naturally avoid any fools causing trouble.

Soon, from a large tent in the center of the camp, Kanae Kocho, dressed in a white doctor's uniform, came out alone. She took off her mask and looked at Shinobu Kocho and Kanae Tsuyuri, who were chatting, with a somewhat helpless expression, and casually greeted them.

"Sister? Why are you out here?"

Upon hearing her older sister's voice, Shinobu Kocho, who was chatting with Kanae Tsuyuri, turned around and rushed into her sister's arms. After cuddling and kissing her affectionately, she asked her sister a question with some curiosity.

"Well, Mo Jun said the later experiments might be a bit cruel, so he let me come out first..."

When asked about this, Kanae Butterfly, who was holding her younger sister, clearly thought of the scene just now. She glanced at the tent behind her and avoided the question, trying to gloss over the topic as much as possible.

Of course, Kanae Butterfly knew that the various experiments her man had just conducted were extremely cruel to those demons. For example, determining the limits of a demon's regenerative abilities and comparing different conditions of a demon's blood, cells, bone marrow, and organs involved cutting into the demon's body while it was still alive. The cruelty of these experiments was absolutely comparable to the most severe torture.

However, Kocho Kanae herself couldn't object. The demons used by the demon god Li Mo for his experiments all came from Fujikasake Mountain. Kocho Kanae, who had also passed the final trial of Fujikasake Mountain, even witnessed many of her fellow trainee swordsmen who had undergone the trial in the same period not leaving Fujikasake Mountain and dying at the hands of those demons, or even becoming their food. It was impossible for her not to have some resentment about this.

Moreover, the demons in Fujikasake Mountain truly devoured people, and many of them ate more than one or two people. It's not that they weren't strong, but rather that the Demon Slayer Corps wanted to use them as whetstones to hone their prospective swordsmen. In the true opinion of most members of the Demon Slayer Corps, it would be best to simply eliminate all these man-eating demons. In fact, if they were kept in Fujikasake Mountain, they could either be imprisoned until death or killed by prospective swordsmen. But now that they have been captured by the demon god Li Mo for experimentation, it is, in a sense, a matter of reaping what you sow.

Most importantly, while Kanae Butterfly does have some sympathy for ordinary people who are forced to become demons, her thoughts are definitely not at the level of a white leftist saint. She will not hesitate to kill demons either. At most, if she finds that the demon god Li Mo is being a bit too cruel, she will simply follow Li Mo's instructions and not be present. In any case, out of sight, out of mind, she will not think about it anymore and will completely regard those demons as already dead.

Of course, Kanae Kocho wouldn't tell Shinobu Kocho and Kanae Tsuyuri directly about this. The two of them had some guesses about the fate of those captured demons, but guesses didn't matter as long as they weren't proven.

"Oh, sister, how did we do today?"

Hearing Kanae's vague words, Shinobu, who was being affectionate with her older sister, paid no attention. She had no interest in the fate of those demons. Instead, she excitedly pulled her sister along, proudly showing off her current strength: "I've reached the stage of activating the power of blood and qi in the Qi and blood martial arts. According to that guy Mo, reaching this stage means I can activate my own blood and qi for attack or defense. But those demons today were too weak, so I didn't need to use them at all!"

Shinobu Kocho's posture was very smug, but her fair, jade-like hands possessed the power to easily crush steel. Moreover, if there were top masters of traditional Chinese martial arts present, they would find that the pores on Shinobu Kocho's arms were completely closed, indicating that her internal strength had reached a high level and even reached the point of transforming softness into hardness. In traditional Chinese martial arts, this would be equivalent to the level of a Grand Master.

With this level of martial arts skill, she could kill dozens of strong men wielding cold weapons with her bare hands. With a little training, she could even dodge the fire of one or two automatic guns. In the era of cold weapons, if she wore heavy armor, she would be a fierce general on the battlefield. Even in the world of Demon Slayer, she would be considered a character. Moreover, Shinobu Kocho fused with the core of extraordinary power, which greatly improved her own aptitude and elevated her physical condition to the level of life essence. Even in terms of pure physical qualities, she was no less than those demons.

Without going into too much detail, Shinobu Kocho's current height has reached 1.7 meters, which is completely different from her previous height of just over 1.5 meters. Unaware people might mistake her for an 18-year-old beauty, but they don't know that this young beauty can easily knead a piece of steel into a dough-like shape, has the strength to easily lift a Hand Demon weighing tons, and already possesses a sharp combat intuition similar to a sixth sense.

Therefore, it would be no problem for Shinobu Kocho to face the Hand Demon alone. With her current strength, she and Kanae Tsuyuri could easily be considered Pillar-level powerhouses in the Demon Slayer Corps. The ordinary demons of Fujikasane Mountain and the hidden boss, the Hand Demon, would be no match for them.

"Sister, I tried my best too!"

Seeing Shinobu Kocho affectionately hug Kanae Kocho, Kanae Tsuyuri, who was standing to the side, was not to be outdone. She also moved closer to Kanae Kocho, holding her arm and talking to her. She had almost returned to normal human emotions. She was still unwilling to talk much and had a cold attitude towards strangers. However, when she was with her man and her two older sisters, the girl showed a very clingy and affectionate attitude.

Especially Kanae Kocho and Shinobu Kocho, her two adoptive sisters rescued her from human traffickers and saved her from that hellhole. They were also exceptionally kind to her. Kanae Tsuyuri has long regarded them as her closest people. Of course, now we also have to add the demon god Li Mo!

"Yes, Kanae is a wonderful child too!"

Seeing Kurihana Raku Kanae's clingy behavior, Kocho Kanae smiled slightly and pulled her stepsister, who was no different from her own sister, into her arms. She coaxed the beautiful girl as if she were a child, showing great patience and maternal love.

As for Kanae Kocho, she is very gentle and generous to everyone. When it comes to her two younger sisters, she is just as strict when it is necessary to train them, but she takes good care of them in daily life. She can be said to play the role of both an older sister and a mother. For her, taking good care of her two younger sisters is a very happy thing. Just like in the original story of "Demon Slayer", she was worried about her sisters even when she was dying.

If possible, Kanae Kocho would prefer that her two younger sisters not have to stay in the Demon Slayer Corps, but could grow up, get married, and have children like ordinary girls. However, Shinobu Kocho and Kanae Tsuyuri would not do that. They both joined the Demon Slayer Corps with Kanae Kocho. For example, in the original storyline of "Demon Slayer", Shinobu Kocho witnessed her own sister die in her arms and hated the demons and the Upper Moon demon Doma who killed her sister. She did not hesitate to use herself as bait to finally kill the Upper Moon demon Doma.

Compared to Shinobu Kocho, who perished alongside Upper Moon demon Doma, Kanae Tsuyuri's ending in the original Demon Slayer storyline was much better. At least she survived the final battle. At most, she lost one eye due to using her self-created technique, but she still survived without any other serious injuries. She then lived with the male protagonist, Tanjiro Kamado, which fulfilled Kanae Kocho's expectations for her younger sister's future.

Now, the fates of Kanae Kocho, Shinobu Kocho, and Kanako Tsuyuri have changed. Having left the Demon Slayer Corps to follow the demon god Li Mo, their lives can no longer unfold as they did in the original Demon Slayer manga...

……

"Mo? Are you done with your work?"

After nearly ten hours, Kocho Kanae, Kocho Shinobu, and Kurihana Kanae had all finished resting, gotten up to wash, and completed their morning training. Only then did Kocho Kanae see the ghost god Li Mo leisurely walk out of the large tent in the center of the camp. She quickly went up to greet her man warmly.

As someone who had been completely devoured by the demon god Li Mo, and whose heart was completely devoted to him, Kocho Kanae naturally valued her man very much. If it weren't for the fact that Li Mo asked her to leave last night and rest with her two younger sisters, even though Li Mo's experiments on those evil spirits were extremely cruel, Kocho Kanae would have stayed by his side to help him. The reason was that, apart from the fact that those evil spirits had indeed eaten a lot of people, she firmly supported all of her man's decisions.

Especially for those demons captured from Fujikasane Mountain, Kanae Kocho really wouldn't speak up for them. Perhaps she sympathized with the ordinary people who were turned into demons out of her own nature, but it's normal for man-eating demons to be killed by Demon Slayer Corps swordsmen. The demons captured from Fujikasane Mountain were all man-eating demons, not weak ones. Moreover, the Demon Slayer Corps needed to prepare whetstones for swordsmen, so they had already dealt with them.

Now that the ghost god Li Mo is using them as test subjects, Butterfly Kanae silently mourned for a moment, then decided to ignore it and had no interest in knowing what would happen to them. She was more concerned about her man.

"Yes, it's really not bad, this time we've achieved good results!"

Seeing Kocho Kanae's friendly demeanor, the demon god Li Mo reached out and hugged the beautiful girl's waist, kissed her affectionately, and then greeted Kocho Shinobu and Tsuyuri Kanae who ran over, and said very pleasantly about his gains last night.

"Huh? Brother, you're studying those evil spirits. Did you discover something?"

Upon hearing what the ghost god Li Mo said, Shinobu Kocho immediately perked up. Although she didn't know much about what happened last night, she did know that the ghost god Li Mo was experimenting on those evil spirits, and she was very curious about what kind of results her man's research would yield yesterday.

It's important to know that the Demon Slayer Corps has never relaxed its research on demons. However, they can't capture powerful demons, and they can't research much from ordinary demons they can capture. After developing a few products that are relatively effective against demons, such as the Nichirin Blade and wisteria flowers, the Demon Slayer Corps' research on demons has basically made little progress. The ordinary demons they capture later are just thrown into Mount Fujikasane as whetstones for the Demon Slayer Corps' induction trials.

In response to Shinobu Kocho's question, Oni-God Li Mo smiled slightly, reached into his [Shadow World], took out a transparent, sealed test tube, shook the unusually dark black liquid inside slightly, and said with great interest:

"Look! This is the [Primordial Demon Blood] extracted from those evil spirits!"

Chapter 12 The Mystery of the Ghost Blood

Progenitor's Blood!

Upon hearing the term uttered by the ghost god Li Mo, Kocho Kanae and the others' eyes narrowed. Having been taught a great deal by the ghost god Li Mo during this period, they naturally knew what this "Progenitor Ghost Blood" was, the key reason for the true birth of evil spirits.

Similar to vampires developing their own offspring and using their own blood to create future vampires, Muzan Kibutsuji, the Demon King of the Demon Slayer world, is undoubtedly a coward and has an extremely hostile attitude towards the demons he creates, making him the most despicable boss of all. However, he can use his own blood to create demons, and if he is willing to give ordinary demons some demon blood, he can make those demons even stronger.

As for other demons, it is very difficult for them to create lower-level demons. This is not only because of the restrictions imposed by the scum boss Muzan Kibutsuji, but more importantly, because creating lower-level demons requires them to give up their own "Progenitor Demon Blood". Since "Progenitor Demon Blood" determines the upper limit of a demon's strength, how could they possibly squander it?

It's important to know that the "ancestral demon blood" possessed by demons cannot be increased unless it is bestowed by the Demon King Muzan Kibutsuji, or by fighting other demons in an attempt to steal it, but both of these methods are basically unreliable.

As for the former, just by looking at his nickname, you can tell that the scoundrel Muzan Kibutsuji had no intention of promoting him to create demons. He simply used the demons he created as tools. Apart from the Twelve Demon Moons, which he valued a little and treated as important tools, the other demons were just numbers in his eyes. He could easily create more with his demon blood, so naturally he wouldn't easily bestow his demon blood upon them.

The latter is equally difficult. It is very rare for demons to devour each other. They are more interested in humans as food. Moreover, it is difficult for ordinary demons to devour their opponents who are also ordinary demons. In addition, it may attract the attention of the scoundrel Muzan Kibutsuji. It is very difficult for demons to devour each other and become stronger.

However, for a demon to create a lower-level demon, the [Primordial Demon Blood] is a necessary condition. Even ordinary demons find it difficult to create lower-level demons. Not only is the [Primordial Demon Blood] they possess very little of, but more importantly, they have absolutely no experience in creating lower-level demons. Demons like Muzan Kibutsuji and the Twelve Demon Moons do have extensive experience in creating lower-level demons, but they won't rashly create them unless they feel it's necessary or they are willing to do so.

As for Li Mo's previous encounter, it was purely a low-probability event. The extremely thin [Primordial Ghost Blood] that had been contaminated with ghost blood actually successfully transformed into something else. In cases where evil ghosts transform into lower-level evil ghosts, this would be an extremely rare example. Li Mo now knows the situation, but he has already rebuilt the foundation of his extraordinary power with [Yin Yang Escape], so he no longer needs to worry about the limitations of the [Primordial Ghost Blood].

Now, almost all of the dozens of evil spirits on Tengxi Mountain have turned to ashes, but the [Primordial Ghost Blood] they left behind has been extracted by the ghost god Li Mo. It took nearly forty ordinary evil spirits and one alien evil spirit to extract less than one hundred milliliters of [Primordial Ghost Blood].

"...But what's the use of this [Primordial Demon Blood]? Is it to transform evil spirits?"

Looking at the sealed test tube in the hand of the ghost god Li Mo, and the special dark black [ancestral ghost blood] inside, Kocho Kanae and Kocho Shinobu were observing without speaking, but Tsuyukiro Kanae raised a crucial question.

What exactly is the use of this [Primordial Ghost Blood]?

Undoubtedly, this question startled Kanae and Shinobu Kocho, who then exchanged bewildered glances. As for Kanae Tsuyuri, she was even more clueless, as she might not even recognize all the medicines, let alone study demons.

In contrast, Kanae Kocho and Shinobu Kocho both came from families of pharmacists and received education in pharmacology from their parents when they were young. They joined the Demon Slayer Corps and worked at the Butterfly Mansion headquarters. Kanae Kocho even rose to the rank of Flower Pillar and had good medical skills. The Demon Slayer Corps even gave Kanae Kocho all kinds of rare medical books from its own archives. She had never read any records about the Progenitor Demon Blood. Shinobu Kocho was even less likely to have read them.

In fact, the Demon Slayer Corps has never stopped researching demons, but since most of its members are people whose relatives and friends were killed by demons, they wish they could exterminate all demons. In addition, the Demon Slayer Corps claims to slay demons and protect humanity, so it is impossible for the Demon Slayer Corps to conduct many imaginative and creative research projects.

For example, if a human is transformed into a demon, is it possible for them to become human again...?

In this respect, the Demon Slayer Corps, which claims to slay demons and protect humanity, cannot directly attempt to turn humans into demons and then find a way to turn them back into humans. First, they cannot bypass the Demon Slayer Corps' ideology, and second, there is the difficulty of such a plan.

Even in the 21st century, with its advanced scientific research, it would be more difficult for humans to transform themselves into another species and then back into one than to land on the moon. At least America was able to send astronauts to the moon with lunar rockets in the late 1960s during the Cold War. Imagine if she managed to turn humans into vampires before the end of the Cold War.

In the world of Demon Slayer, more than a thousand years have passed since the appearance of the Demon King Muzan Kibutsuji. The successive leaders of the Demon Slayer Corps have considered the possibility of turning demons back into humans. However, having ideas and putting them into action are two completely different things. At least, the Demon Slayer Corps' research on demons has progressed very slowly. The discovery of a few counters such as wisteria flowers and Nichirin Blades is already quite good. Occasionally, they have also found some unexpected byproducts, such as the crows with their high intelligence.

At least, the successive leaders of the Demon Slayer Corps have all been focused on eliminating the Demon King Muzan Kibutsuji to resolve the family curse and the rampant demons. When research on demons has not yielded any effective progress for a long time, the level of investment is naturally relatively low. They are not as good as that female demon who, by chance, escaped Muzan Kibutsuji's control and secretly researched how to transform from a demon into a human. She has devoted a great deal of effort to this project.

As for the Progenitor's Blood, the Demon Slayer Corps had never considered its use before. As Kanae Tsuyuri said, they really couldn't imagine what the Progenitor's Blood was for or how they would use it!

"This [Primordial Demon Blood] turns people into man-eating demons who can't stand sunlight but are immortal. Those powerful and wealthy people who eat people without spitting out the bones will definitely love it!"

Seeing that Kanae Kocho and Shinobu Kocho had raised their questions, and that they were speechless before turning to look at him, Li Mo, the Demon God, shook the test tube of [Progenitor Demon Blood] he was holding and directly offered a highly valuable suggestion. Then, seeing the three beautiful girls' angry and dissatisfied eyes, he quickly coughed twice and mumbled:

"Ahem, just kidding. [Primordial Demon Blood] is extracted from the blood of evil spirits. It can enhance the power of evil spirits and create more evil spirits. It can also be used to try and create medicines specifically for evil spirits, such as turning evil spirits into humans..."

Hearing the explanation from the ghost god Li Mo, Kocho Kanae, Kocho Shinobu, and Kurihana Kanae nodded in agreement, feeling that what their man said made sense. However, looking at the smiling ghost god Li Mo, Kocho Kanae felt that his so-called joke just now seemed to be a genuine consideration of whether or not to use the [Progenitor Demon Blood] in this way.

If the demon god Li Mo knew what Kanae was thinking, he would definitely say that he had never considered doing that, but he had seriously considered the use of the [Progenitor Demon Blood].

Strictly speaking, after merging the powers and memories of the various Li Mos in the [White Mist Space], the demon god Li Mo looked down on Muzan Kibutsuji, the Demon King from the original Demon Slayer anime. He considered Muzan to be the worst villainous boss he had ever seen.

Judging from the original plot of "Demon Slayer", the Demon King Muzan Kibutsuji has lived for at least a thousand years. For an ordinary person with a bit of ambition, a thousand years would probably be enough to achieve something. However, Muzan Kibutsuji did nothing but create some demons and search for the Blue Spider Lily in those thousand years.

Or rather, the Demon King Muzan Kibutsuji, having lived for over a thousand years, has only mastered the essence of "survival," pushing his instinct for clinging to life to the extreme and developing the technique of escaping by splitting his soul into thousands of pieces. He has learned no other useful skills, lacking any combat or organizational abilities. Aside from relying on his own strength to intimidate the weak, he is probably not even as capable as his own Twelve Demon Moons. He has not even unified the demons he created, nor has he demonstrated any value in them.

Look at the vampire bosses in those vampire movies or anime. They also rely on drinking human blood to survive and are extremely vulnerable to things like sunlight, silver, and garlic. However, these vampire bosses or vampire clan bosses are able to make full use of their ability to develop bloodline offspring, directly winning over human elites or nobles. They perfectly utilize their ability to develop bloodline offspring, completely overwhelming Muzan Kibutsuji by many levels.

Without going into details, Li Mo, the Ghost God, felt that if he were in the position of the Demon King Muzan Kibutsuji, and directly used the [Progenitor Demon Blood] to transform the Japanese conglomerates and high-ranking officials, he would probably have already become the supreme ruler of Japan. Those people who would do anything for immortality are the ones who hold power in Japan and are the kind of guys who eat people without spitting out the bones.

In any case, in Japan, the exploitation of ordinary people by daimyo, merchants, and samurai has been a long-standing tradition. It wouldn't be an exaggeration to say that they were feeding on the blood and flesh of Japanese farmers. Even after the Shogunate era was replaced, the newly established so-called "heavenly locusts" and their powerful figures were just as greedy, and their exploitation was even more brutal than during the Shogunate era. Even though Japan received a lot of benefits from World War I, it had nothing to do with ordinary Japanese farmers; they were almost entirely devoured by these powerful figures and so-called "heavenly locusts."
