I simultaneously traverse countless worlds

"That's right! The medicine I'm researching requires the blood of a sufficiently powerful demon, or even the blood of a demon king, but that's just too difficult!"

Faced with the speculation of the ghost god Li Mo, the female ghost doctor Zhu Shi was somewhat surprised. She put down her teacup, felt the slightly bitter taste of the tea she was tasting, and helplessly revealed a key reason for the slow progress of the research on the "human transformation drug".

Researching how to turn demons into humans naturally requires relevant research materials. Humans as a comparison are relatively easy to find; the female demon doctor Tamayo can simply pay someone to examine them or find corpses directly in the hospital. However, she is truly powerless when it comes to materials related to demons. Even though the Demon Slayer Corps has provided some blood from ordinary demons, the blood of the Twelve Demon Moons or the Demon King is impossible.

Are you kidding me? Among the Twelve Demon Moons, even the six weakest Lower Rank Demons are comparable to ordinary Pillar-level powerhouses in the Demon Slayer Corps. Some are even powerful and cunning Lower Rank Demons with the ability to directly kill Pillar-level powerhouses in the Demon Slayer Corps. How can the Demon Slayer Corps obtain their blood smoothly in the midst of fierce battle?

This is akin to the naive idea that one should think about minimizing friendly fire during a brutal war. The Demon Slayer Corps swordsmen, fighting against Lower Moon demons, probably don't have the energy to spare for anything else. Winning is already incredibly difficult enough, let alone trying to collect the blood of Lower Moon demons. That's like dancing on the edge of a cliff, thinking they've lived long enough, or simply choosing to die. It's something extremely difficult to do.

If the Demon Slayer Corps were to gather all its Pillar-level fighters, it might be possible to attempt to capture the Twelve Demon Moons. However, the Twelve Demon Moons are not fools; their strength is immense. If the Demon Slayer Corps were to capture even one or two, the price they would have to pay would be far too high for them to bear. Moreover, the probability of successfully completing this plan by collecting the demon blood of the Twelve Demon Moons for the other demon they were cooperating with is extremely low.

As for the Demon King Muzan Kibutsuji, let alone the Demon Slayer Corps finding his whereabouts, even if they did discover his hiding place, they would still have to fight tooth and nail to eliminate him. Why would they bother collecting the Demon King's blood to make the "human-transforming drug"? That would be pointless.

In this light, it's no surprise that the progress of the "human-transformation medicine" on the female demon doctor Tamayo's side is slow. Lacking the blood of powerful demons as research samples, the demon blood of female demon doctor Tamayo and Yushiro is already subtly but significantly different from the blood of Demon King Muzan Kibutsuji and his demons. Moreover, with even the crucial Nezuko Kamado absent, it's extremely difficult for female demon doctor Tamayo to make a breakthrough in this area.

Simply put, the female demon doctor Tamayo's "human-transforming medicine" research project lacks many important research materials. Relying solely on studying humans and a small amount of demon blood, even if Tamayo and Yushiro together could be considered demon research subjects, she cannot use herself and Yushiro as guinea pigs. The research is mostly conducted through comparative studies, and the lack of several key research materials makes the development too difficult.

Even if all the materials are gathered, the time required for the female ghost doctor Tamayo to successfully develop the "human-transforming drug" is unknown. It could take several months, a year or two, or even ten or eight years...

"That's it..."

The ghost doctor Tamayo did not question what the ghost god Li Mo said. He calmly picked up a piece of the pastry in front of him and tasted it. He felt the sweet and delicious taste of the pastry, and then a trace of disappointment flashed in his eyes.

Originally, Ghost God Li Mo was hoping to obtain the [Human Transformation Medicine] directly. Although he himself did not intend to become human through it, the special changes between the [Human Transformation Medicine] and evil spirits were enough for him to study its mysteries. If he could truly unravel the secret of the mutual transformation between evil spirits and humans, it would be a great gain for Ghost God Li Mo, and it would be of considerable use even in other alternate worlds.

Now, the ghost god Li Mo calmed down. He seemed to have overestimated or underestimated the difficulty of developing a drug to turn demons back into humans, given the lack of sufficient materials and assistants. It was already a very rare situation that the female ghost doctor Tamayo was able to break free from the control of the demon king Muzan Kibutsuji and stop eating people and start drinking blood. Expecting her to do things according to his wishes was too idealistic.

As for the female ghost doctor Tamayo, Li Mo's interest in her diminished considerably. Although this female ghost doctor was indeed very skilled in medicine, he didn't need any doctor's help at the moment. To him, the Demon King Muzan and his gang of evil demons were undoubtedly just a bunch of worthless bastards. It was better for him to explore the secrets of the Demon Slayer world, which was simply to clear out these unstable factors in advance.

Thus, Li Mo, the ghost god, felt that the preconceived notion of the female ghost doctor Tamayo was a negligible issue. In any case, the degree of harm she and Yushiro posed to humans was probably less than that of those robbers or bandits who murdered for money, and could be completely ignored!

"Well then, Ms. Tamayo, we are truly sorry for disturbing your life this time!"

After only a dozen seconds of deliberation, Ghost God Li Mo stood up and bid farewell to the female ghost doctor Tamayo. He politely said a few words to her, and then gestured to Kocho Kanae, who had not spoken, that he was preparing to leave rather than recruit her, because her abilities were of little use to him.

"Mr. Li Mo, there's no need to be so polite. Let Yushiro and me see you off!"

Seeing that the ghost god Li Mo was politely bidding farewell, the female ghost doctor Tamayo was also somewhat surprised, but she quickly recovered and got up to see them off. She and Yushiro respectfully saw off the ghost god Li Mo and his party, and only felt at ease after watching them leave in their carriage.

Even though the female ghost doctor Tamayo treated the ghost god Li Mo with respect and without any concealment based on her intuition, the heavy feeling that seemed to weigh on her heart still made both Tamayo and Yushiro uneasy. Fortunately, when the ghost god Li Mo heard that her "human transformation medicine" was not completed and would not be of much use to him, he chose to leave. Watching the convoy of the ghost god Li Mo and his party leave, the female ghost doctor Tamayo decided to move.

The ghost god Li Mo, who had already left, was unaware of Tamayo's decision. Even if he had known, he might not have cared about it, because he had lost interest in Tamayo and was now preparing to target the evil ghosts instead!

Chapter 22 Target! Yoshiwara Red-Light District!

"Mo, are we going to other places?"

Later, when she saw that the cars she and her group were traveling in were not returning the way they came, but instead heading in another direction from Tokyo, Kocho Kanae, who had just come to her senses from the conversation between the ghost god Li Mo and the female ghost doctor Tamayo, had a premonition and asked a question.

It's obvious that Kanae Butterfly has confirmed the situation just now and that they don't need to fight. So, besides that one person being a genuine guest, what else could be worth Guishen Li Mo taking them along?

They even prepared themselves in advance, dressed in combat-ready attire, and brought their weapons to the vehicle, looking ready to be used at any time. If they weren't preparing for battle, no one would believe it. Since it wasn't the female ghost doctor Tamayo, Kocho Kanae naturally deduced that there was another target.

Upon hearing Kanae's words, Shinobu Kocho, Kanao Tsuyukiro, and Mitsuri Kanroji snapped out of their daze and looked directly at the demon god Li Mo with some eagerness. They were completely confused about the conversation just now, but they were much more enthusiastic about the battle!

"That's right!"

Seeing that the eyes of Kanae and the other beautiful girls were all on him, the demon god Li Mo nodded firmly in confirmation. After recalling his next preparations, he looked at the girls and said with a playful tone, "Next, our target is one of the Upper Moon demons of the Twelve Demon Moons. She is currently hiding in the Yoshiwara entertainment district, so we need to do some disguise to infiltrate her!"

That's right, the person that the demon Li Mo was referring to was none other than the Upper Moon Six, Daki, and Gyutaro, who appeared in the Yuuka arc of the original Demon Slayer anime. He remembered that the twin demons of this Upper Moon demon hid in the Yoshiwara red-light district of Tokyo and later fought against the protagonist and were defeated.

As it stands, it's estimated that the story of Demon Slayer hasn't even started yet. The Upper Moon Six demon Daki and Gyutaro are probably still living in Yoshiwara's red-light district, secretly eating people. Daki might even be debuting as a courtesan. I wonder what those who discover Daki's true identity will feel when they try to get close to the beautiful courtesan and find out that she is actually a man-eating demon?

Anyway, Ghost God Li Mo felt that it definitely wouldn't be a good mood. Just looking at the underground cave below the Yoshiwara entertainment district where Daki and Gyutaro were, there were countless human skeletons piled up, estimated to be at least three figures, and if we were to be generous, it would probably be four figures. These man-eating demons need no further explanation; they are targets that Ghost God Li Mo must eliminate. It's a good opportunity to deal with them now.

However, the demon god Li Mo himself would not take action. Looking at the four beautiful girls in front of him, he decided to let them practice on Daki and Gyutaro, while he stood by as a backup. He didn't have to worry about any unexpected situations arising in this battle.

"Yoshiwara entertainment district? Should we just go straight in?!"

Upon hearing what Guishen Li Mo said, Kocho Kanae remained calm and composed. Kocho Shinobu and Tsuyukiro Kanao blushed slightly, while Kanroji Mitsuri seemed somewhat flustered and couldn't help but ask her man again to confirm the place they were going to next.

"Don't worry, we'll just use some disguises and won't openly enter the Yoshiwara entertainment district!"

Seeing Kanroji Mitsuri's flustered state, the ghost god Li Mo glanced at her with interest. He knew that this beautiful girl, who used to yearn for love, occasionally read some pamphlets with ambiguous content, but at this moment, instead of saying anything, she began to explain.

To be honest, even if Kanroji Mitsuri knew what Yoshiwara was, and was too shy to openly enter that place, the demon Li Mo would understand but wouldn't allow it. At most, he would have the girls take some disguises so that the people of Yoshiwara wouldn't recognize them as women, and then go to Yoshiwara to fight the Upper Moon Six, Daki, and Gyutaro's last duo.

Therefore, after instructing Kocho Kanae and the others, the demon Li Mo had them change into disguises and hide their weapons. He also informed them of the Upper Moon demons they were going to deal with before quietly leading them to Yoshiwara's entertainment district!

……

Yoshiwara Entertainment District!

As night falls and the moon rises, this place becomes a paradise for men. The flower street, which is home to hundreds of shops specializing in business with men, is filled with laughter and joy.

There were women in beautiful kimonos dancing upstairs, beckoning customers to come and go. There were also courtesans in ordinary kimonos who directly pulled men who had just entered to solicit customers. There were even courtesans whose natural beauty was on full display, waving to customers as they entered. The smell of perfume and alcohol permeated the entire Yoshiwara geisha district.

This is a street of pleasure, but also a street of sin. Prostitutes and customers come and go, frolicking with each other, but in reality, it is a transaction of money and women. Except for a very few men who have other purposes, most men who come here have heard of the reputation of Yoshiwara's red-light district and come to have fun. Some come directly to find women, while others are willing to spend money to chat and laugh with prostitutes and spend the night together. Some are rich and powerful and are preparing to find the most beautiful courtesan. In the end, their goals are no different.

For the courtesans and even the most popular courtesans of Yoshiwara, apart from a few who were born and raised there, the vast majority were sold into Yoshiwara. Among them were even a few girls from fallen samurai or noble families. Regardless of their previous background, once they entered Yoshiwara, they became courtesans. They were then trained from the lowest level, "bald," and depending on the situation, they might be given special training to become the most popular courtesan, or they might become the most ordinary courtesan.

In a sense, the Yoshiwara red-light district was clearly divided into different classes. The most common brothels simply charged women according to their prices. The mid-range shops offered drinks and food, and the women there were quite knowledgeable and could even converse with ordinary officials and samurai. As for the highest-class courtesans, one needed to be both attractive and wealthy to appreciate their charm.

The problem is that Yoshiwara's entertainment district wasn't doing this to run a charity. The owners of each establishment took the lion's share of the courtesans' and brothel's earnings. Getting these women to redeem themselves was extremely difficult. Unless they encountered a wealthy and generous customer, there was only a small chance of them escaping Yoshiwara's entertainment district. Otherwise, the fate awaiting these women, from brothel girls to courtesans, was to die from various diseases in Yoshiwara's entertainment district and be buried in an unmarked grave.

No one knows how many courtesans die silently and are buried in Yoshiwara every year. All people see is that every afternoon, courtesans dressed in various gorgeous kimonos solicit customers in Yoshiwara. Every day, hundreds or thousands of men come to Yoshiwara to enjoy themselves. All they want to do is have a good time and not care about the future of the courtesans.

When the group of ghost god Li Mo arrived at Yoshiwara's brothel and stepped into it through the main gate, the men who came to spend money and the prostitutes who came up to chat looked at these mysterious people wearing cloaks with curiosity, but no one went up to ask about their origins!

Won't this arouse suspicion?

Seeing the curious looks from passersby and women around her, Shinobu Kocho felt like she was being used as a monkey show. However, when she realized that no one was coming to ask her anything, she looked at the people who had led the way and understood. She then asked her lover to confirm.

"No, those few are responsible for maintaining order in Yoshiwara's geisha district!"

To this question, the cloaked and masked demon Li Mo answered Shinobu Kocho's question with certainty. He pointed to the few pawns he had placed in Yoshiwara's red-light district, then to the hidden guards at the entrance, and calmly explained, "With them leading the way, naturally no one will question or stop us. It would be difficult for ordinary people dressed like this to walk in directly, and it would be difficult for courtesans to escape Yoshiwara..."

If it were an ordinary person, they wouldn't be wearing a cloak when they come to Yoshiwara's red-light district. Even if there were such a mysterious person, the guards stationed at the main gate of Yoshiwara's red-light district would still investigate the situation. This place does not allow any accidents, nor does it allow the courtesans to escape.

After all, Yoshiwara is a famous entertainment district in Japan, providing a large amount of tax revenue to Japan every year. It is also related to the private income of many Japanese elites. They are even capable of openly organizing large numbers of Japanese girls to be sold to Southeast Asia. It is not hard to understand that someone like Ququ supports Yoshiwara behind the scenes and receives a considerable income every year. In fact, it is considered a matter of course in Japan.

In this way, Yoshiwara's brothel has a very unique architectural structure. There are no side doors, only one main entrance. The rest of the area is surrounded by walls and moats, and there are people patrolling from time to time to prevent the prostitutes from escaping. The daytime is when various supplies are transported or garbage is collected. The business hours are from evening to morning. Moreover, the main entrance of Yoshiwara's brothel is guarded 24 hours a day. Prostitutes who want to escape are one in a thousand lucky ones.

However, for the ghost god Li Mo, he didn't need to consider the defense measures of Yoshiwara's red-light district at all. With a large amount of power at his disposal, he had also placed several pawns. When the leaders in charge of the daily order of Yoshiwara's red-light district appeared to greet him, whether they were courtesans who knew his power or men who came to seek pleasure, they were very wise not to come over to ask anything, and even took the initiative to walk towards the surrounding shops.

Soon, under the guidance of the local tycoon, Guishen Li Mo and his group arrived at the middle section of Yoshiwara's entertainment district. This was the most upscale area of ​​Yoshiwara's entertainment district, and the bustling scene of people coming and going made Kocho Shinobu and the others more vigilant.

"Kyogoku-ya? Sumire, if there's a demon in this house, aren't there too many people?!"

When she saw the brothel called "Kyogoku-ya," Kanae Kocho looked at the bustling scene at the entrance and the at least three-digit number of customers inside. Her beautiful eyebrows furrowed involuntarily, and she asked her man with some hesitation.

It's not that Kanae Kocho is afraid of fighting demons; it's just that she considers other factors more. In a place like Yoshiwara, with so many people, openly fighting demons would have a terrible impact. Besides, judging from the current bustling scene at Kyogoku-ya, there are at least several hundred servants, courtesans, and customers inside. She can't just ignore them and rush in to fight demons, can she?

In this situation, Kanae Kocho considered things more carefully. If it were Shinobu Kocho or Mitsuri Kanroji, they wouldn't think that much at all. They would probably just charge in and fight the evil spirits at the command of the demon god Li Mo!

"Don't worry, there won't be so many people in a little while!"

Regarding Kanae's consideration, the demon god Li Mo nodded slightly. He originally didn't care about this issue, but considering his woman's concern, he was prepared to take action to disperse the crowd. Otherwise, given the Upper Rank Demon's fighting strength, Kanae and the others might not be able to defeat him quickly, so it was better to play it safe.

As the words of the ghost god Li Mo fell, an invisible spiritual force enveloped [Kyogoku-ya] and even affected the entire Yoshiwara brothel. The men and prostitutes who were originally there to seek pleasure stopped their actions with dazed expressions, as if something had happened, and began to turn around and leave through the main entrance of Yoshiwara brothel. The thugs of Yoshiwara brothel who used to arrest and stop those prostitutes also had the same confused expressions and left Yoshiwara brothel one by one.

Seeing this unusual scene, the three beautiful girls, Kanae Kocho, Shinobu Kocho, and Kanako Tsuyuri, were alright, as they had at least witnessed the supernatural abilities of the demon god Li Mo before. However, Mitsuri Kanroji stared wide-eyed, as she had never seen anything like it before. Fortunately, all four girls were resolute and understood what the demon god Li Mo was planning to do. Naturally, they protected the demon god Li Mo and prevented the Upper Moon demon from discovering them and attacking them.

At this moment, it was only after the demon god Li Mo had influenced the people at [Kyogoku-ya] to leave that he managed to evacuate the last few hundred people in a short time. Then, he slightly turned his head to signal the four beautiful girls to prepare for battle and go and kill the Upper Moon demon hiding among them!

……

"Huh? Why did the sounds outside stop?!"

In just a few minutes, in the private room of the top courtesan at [Kyogoku-ya], Daki, the Upper Moon Six, dressed in an exceptionally beautiful twelve-layered kimono, suddenly sensed something was amiss and looked up with some suspicion at the outside.

Daki, the Upper Moon Six!

Strictly speaking, Daki and her brother Gyutaro together constitute the complete Upper Moon Six demon. However, under normal circumstances, Gyutaro is asleep inside Daki's body, only appearing and taking the lead in battle when Daki is in danger or injured.

Gyutaro and Daki were born into the lower class of Yoshiwara, during the shogunate period more than a hundred years ago. If things had gone according to plan, they would likely have become nameless ghosts in Yoshiwara like many other courtesans. However, one day, Daki got into a fight with a samurai who came to drink, and accidentally blinded him in one eye. He then set her on fire and almost burned her to death. Her brother Gyutaro carried her and called for help, but no one came to her aid.

Later, by chance, they encountered an Upper Moon demon. Gyutaro and Daki, who had transformed into demons, became the hidden bosses of Yoshiwara's entertainment district. They secretly devoured countless people, rising to the sixth of the twelve demon moons. After hundreds of years, Daki, who used to make her own decisions, hid in Yoshiwara's entertainment district as a courtesan. Every ten years, she would change her appearance and name. Occasionally, when she encountered trouble, she would awaken her sleeping brother Gyutaro, who would then solve the problems she faced.

At this time, Daki was using the alias "Waraki-hime" and was the courtesan of "Kyogoku-ya". While enjoying the luxurious treatment of a courtesan, she would secretly select targets, such as young and beautiful girls, strong young men or children, who would occasionally be listed as her prey. In the chaotic Yoshiwara red-light district, it was quite common for someone or a courtesan to disappear occasionally, and few people would investigate it.

The problem is that Daki was completely unaware of the danger at this moment. Having lived a carefree life in the Yoshiwara entertainment district for over a hundred years, her combat instincts were even inferior to some lower-level demons. She was simply not used to the sudden loss of music and voices and failed to react in time!

"Die, you evil spirit!"

While Daki was still wondering what was going on, she heard Kanroji Mitsuri shout, followed by several specially made short spears flying into the house. Caught off guard, she dodged several of the spears, but one of them grazed her left shoulder.

Like the demons who had tasted the power of the degraded version of the [Yin Yang Release] weapon, Daki, experiencing the pain of her soul being wounded, let out a sharp scream. However, the beautiful girls who had joined forces, including Kocho Kanae, Kocho Shinobu, and Tsuyuri Kanako, paid no attention to her scream. They formed a dense attack net with long-handled naginata, katana, and projectile short spears, swarming forward and injuring Daki once again. It wasn't that Daki didn't want to dodge, but she had just been injured and hadn't reacted in time, resulting in one of her arms being severed.

Now, the badly injured Daki could no longer hold back. She quickly activated her Blood Demon Art to create multifaceted ribbons and transformed into a demon. She immediately woke up her brother Gyutaro. At this moment, Daki rushed out of Kyogoku-ya and found that Yoshiwara's geisha district was now empty!

Chapter 23 Daki and Gyutaro

Under the cover of night, Yoshiwara's red-light district was still brightly lit, but apart from the occasional bottles of wine and food in each shop, and the occasional folding fans and coins lying around, there were no ordinary people staying in this den of extravagance.

Daki and her brother Gyutaro, both Upper Moon Six demons who have changed drastically, were somewhat bewildered. They had lived in Yoshiwara's entertainment district for over a hundred years and had never seen it so deserted. Even when the weather was extremely bad, Yoshiwara's entertainment district would still have customers who would spend money or even stay overnight.

Looking around Yoshiwara now, you can't see any ordinary people. If Daki and Gyutaro were to go to the top floor of Kyogoku-ya and look out, they might still see ordinary people running out of Yoshiwara. The prostitutes, customers, and even servants all ran out of Yoshiwara with blank expressions, and then, for whatever reason they could think of, either went home to rest or chose to escape. In any case, they wouldn't stay in the Yoshiwara area.

In fact, the techniques used by the demon god Li Mo were derived from the genjutsu transformations of the Naruto world. He used spiritual power directly instead of chakra, and the effect in the Demon Slayer world would be far stronger than any Blood Demon Art. The prostitutes and servants of Yoshiwara were simply released. Every single customer who went to Yoshiwara to seek pleasure was sent home to sleep. As for the reasons, they were left to their own thoughts to explain, and they had no doubts about it.

Simply put, Li Mo's move was equivalent to a super-large-scale "Idle Man Expulsion" magic, but it was a variant illusion powered by mental energy. In the world of Demon Slayer, apart from those Demon Slayer Corps swordsmen or demons with extremely strong wills, ordinary people would have absolutely no resistance. As for ordinary people in Yoshiwara's entertainment district, they would leave the place very easily.

For Kanae and the others, they had already seen many of the tricks that the demon Li Mo used, so they were not surprised at all and were facing a powerful enemy. As for Gyutaro and Daki, the two Upper Moon Six demons who had just appeared, they didn't have time to be curious about them. Their current situation was not good at all!

"Brother! Help me, kill these damned bastards!"

Daki, who was only surprised for a moment, was tormented again by the trauma of losing her arm. She tried to cover the wound on her left arm to heal it, while shouting loudly at her brother Gyutaro, who was blocking her way.

At this moment, Daki had withdrawn all her clones. Her hair had turned from black to silver, and her pupils were dyed dark gold. She had also dyed the tattoos on her cheeks to be even more alluring and beautiful. Her attire resembled that of a succubus wearing only a swimsuit. In the present world before the arrival of the demon god Li Mo, such an outfit would probably be considered very revealing. In the world of Demon Slayer, it would be considered excessive even in the Yoshiwara entertainment district, let alone for the Kocho Kanae and the others who fought her.

However, at this moment, Daki's face was deathly pale. Her left arm had been severed an inch above the elbow joint. The wound caused by the degraded version of the Yin-Yang Release weapon had not healed. Instead, it began to decay because of the damage to her soul. Even the demon's super regenerative ability was ineffective against those wounds!

"You...you hurt my sister!!!"
