A person in Japan, a sword that soars to immortality.

"Phew~ I'm finally back."

After a long journey, Taichi finally returned to the inn in Nara-juku.

Standing in front of the Japanese-style room, he looked himself over. Although he was no longer injured, his ripped pants and disheveled hair suggested that the fight hadn't been easy for him.

"I remember the last time it got this serious was in Yamato, thankfully only Aya was with me then..."

Hula......

Before Taiichi could finish speaking, the paper sliding door of the Japanese-style room suddenly opened, revealing Sachi's displeased expression.

"What happened between you and A-Xia?"

"what?"

Taiyi's lips twitched, thinking to himself, "What time is it? Why isn't she asleep yet?"

Before she could explain, she was pulled into the room.

"Where were you just now?"

"Forehead......"

"You are hurt?"

"well enough......"

"Let me take a look for you."

"I don't think that's necessary..."

"Why are you hiding? Don't move!"

"I'm really alright... hiss~~"

[Spiritual Energy +1]

......

The next day, the sun shone brightly.

After leaving the inn, Taiyi and his companions rented a carriage and a horse from the post station.

He rode a horse, while Sakichi and the female ninja rode in the carriage.

Unlike when he captured Rikutaro, he had learned a lot about the Nezu ninjas from Tsukasa.

And the other party was very cooperative along the way, showing no intention of running away.

Taichi felt that since Kanade was a woman, and in the original work, he gave Senta a final act of tenderness, he did not intend to bring her back to Edo in a big way.

In the afternoon, as Edo came into view and its outline became visible, Taichi's thoughts began to stir again.

"Although I am injured, I still have two bottles of Transformation Water. If I use them well, I can not only recover the lost attribute points, but also advance further."

Subconsciously reaching out to touch the two bottles remaining at his waist, Taiichi suddenly had another idea pop into his mind.

That's the blood of cannibals, which can apparently be refined into Yin Pills, something similar to the Transformation Water.

Essentially, they are all Yin Qi. Since I am powerful and possess the inner core fire, I can reverse Yin and Yang and return to the original Qi. There is no reason why I cannot refine the blood of the man-eating ghost.

Similarly, Muzan and Sakura Ryu could also achieve reverse cultivation.

As for the other cannibals, although they can extract the yang energy of the human body or the innate energy in the nine orifices after eating people, they do so not by themselves, but by Muzan's cells.

Those who receive Muzan's blood and become cannibals are essentially Muzan's puppets. The Blood Demon Arts and infinite lifespan they gain are all the work of Muzan's cells.

As strength increases, the nature of life itself will also undergo a leap.

This is also why the higher one's cultivation level, the greater the radiating influence on the surrounding area, and incidentally, why mortals regard them as gods.

Powerful beings possess immense power originating from themselves; they are powerful energy sources.

Even if a nuclear bomb doesn't explode, it still emits nuclear radiation. And an individual capable of unleashing powerful energy is itself a source of radiation.

When Taiyi cultivates, he unconsciously releases some true energy with attributes, such as water-attribute true energy.

This also means that when Zuoqie, whose main attribute in the Five Elements is water, is around him, he will unconsciously absorb this true energy, thereby rapidly improving himself.

"If it really is as I think, then compared to the Water of Change, the blood of the man-eating demon is undoubtedly a better material for alchemy."

Tai tapped his temples, recalling scenes from the Demon Slayer manga's original story regarding the ending.

Is it simpler to erase the will of the Sakura Dragon that has turned into water, or to erase Muzan's consciousness from within the demon blood? The latter is undoubtedly the simpler one.

After being defeated, Muzan injected his blood into Tanjiro's body, and the latter successfully and quickly overcame the sunlight, becoming the Demon King.

Even if he was injected with the drug that turned him into a human, Muzan, who was injected with the drug by Tamayo at the very beginning of the Infinity Castle battle, was actually able to break down the drug.

Tanjiro's aptitude was even better than Muzan's. After becoming the Demon King, there was no reason why he couldn't be broken down. However, it was because of Tanjiro's own will and the calls of his companions that he was able to successfully suppress Muzan.

To this outcome, Taiyi can only say one thing: the hymn to humanity is the hymn to courage, and the greatness of humanity is the greatness of courage.

"But at that time, Muzan's original body was gone, and only his blood remained in Tanjiro's body, which is understandable. If I want to erase these wills, I still need to rely on my own soul power."

At this point, Taiyi couldn't help but look at the attribute panel again.

[Soul: 103.3 (206.7) (+)]

Yes, thank you, Zoche. Last night you not only restored 1 point of my spirit, but also increased my maximum spirit level by 1 point.

"I was able to fight to the end and even win in many deadly battles, one of which was attribute conversion, and the other was the power of my soul."

Of all the three-dimensional attributes, what Taiyi is most satisfied with is the growth rate of his divine soul power.

The effect of spiritual power on Qi is more pronounced the higher it is.

The key to defeating Kokushibo that day was that his spiritual power was higher than his opponent's, which allowed him to amplify his attack power against ki much more effectively.

The battle against the Nezu ninjas at Himeji Castle resulted in a gain of over 200 universal points, a truly bountiful harvest.

If all of this were added to one's divine soul power, not only would it significantly enhance combat strength, but it might even allow one to contend with the consciousness that Sakura Dragon left within oneself.

"Hmm, no rush, we still need to use these general points on the integrated breathing technique."

"If we want to get more general-purpose points, we still need to find some powerful slashers."

As was his habit, Tai started rubbing his chin with one hand. He began to wonder if, after he had recovered, he should first go to Daki and her brother to have some blood drawn, or he should contact the Demon Slayer Corps and do some extra work.

Um......

We need to do both, and we need to make both strong. Only children make choices; adults want both!

"But it's really inefficient for me to do it all by myself."

Thinking that Muzan had been scared away by the Sakura Dragon, Taiichi figured that Muzan wouldn't dare to provoke him again no matter what kind of demon he killed in the future. Then another idea popped into Taiichi's mind.

Since the demons are all near Edo, and I'm moving fast right now, I might as well go back and bring Senta and Fukuchiya along.

Now that I can refine pills, if I can also refine blood, plus optimize the Rejuvenating Water, improve the strength of Senta and the others, and then ask the Demon Slayer Corps for a few more Kasugai Crows.

Everyone split up. As long as Senta and the others are safe and sound, and after discovering the demon, they can hold out until we arrive at the scene, then all that's left is to reap the rewards.

"That's settled then. Let's find the Daki siblings and bleed them out!"
