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

"So? Have you thought it through?"

With his back to Gyutaro and Daki, Taiichi asked the question one last time.

After a long while, just as he was about to lift his leg and leave through the window.

"Hey!"

As soon as he turned around, a glass tube filled with blood arced through the air and landed precisely in his hand.

“If you dare to play me, I will tear you to pieces, even if it means my death.” Gyutaro twisted his neck, stared intently at Taiichi, and continued, “Tell me, what do you want me to do?”

Taiyi carefully put away the test tube, then a slight smile appeared on his lips as he stared intently at the two ghosts opposite him.

Sure enough, I succeeded again.

Becoming one of the Twelve Demon Moons is every demon's dream.

Because all demons have Muzan's cells inside them, are controlled by him, and worship him madly.

Gyutaro only became a demon a few years ago. Although he is very strong, for some reason he is not even a Lower Moon demon. Meanwhile, Doma is currently only an Upper Moon 6.

Although I don't know how they became Upper Moon 2 and Upper Moon 6 in the original story, now that I've come to this world, some things should be done according to my own plan.

Taiichi had already figured out a method. First, he would determine the location of Doma. Although it wasn't mentioned in the original work, Taiichi had a way to find him.

Then, after Doma is promoted to Upper Moon 2, he will help Gyutaro accumulate merits.

Of course, we can't actually let Gyutaro kill the Pillar.

Muzan's method for verifying whether a demon killed a Pillar is to read its memories.

Memory is what the eyes see, or what can be described as fragments of consciousness retained in the brain.

In that case, we can have Gyutaro cooperate with Tamayo to make the brother and sister hallucinate, thus leaving them with deceptive memories, and that will be the end of it.

Having made all the necessary preparations, Taiichi waved to Gyu-fu Taro and said with a smile:

"Come closer, and all you need to do is..."

......

Three days later, at the Yamada residence.

Taiyi, who was in the room, had just finished his cultivation for the day and then began to examine the changes in his body.

"Fortunately, we just need to change the frequency of using the two breathing techniques, Yang Dragon's Roar and Yin Tiger's Howl, from alternating once a day to practicing Yin Tiger's Howl every two days and Yang Dragon's Roar every one day."

"But this is not a long-term solution; we still need to get our hands on the Breathing of Water."

Taiyi opened his eyes and pondered to himself.

Your own breathing method is tailored to you by the system based on your body's natural growth rate.

The appearance of the title effect has led to the problem that the growth rate of Qi and Blood value exceeds the growth rate of Essence value.

"Sigh, I was still in too much of a rush. I always feel like there's not enough time. Oh well, I'll go check on Fu Zhi's medicine and see how it's going."

Taiyi slapped his thigh, sighed, and then got up and walked outside.

These past two days, he went through the plot of Hell Music and Demon Slayer in his mind from his previous life again, and in the end, he discovered something very interesting.

That is, in the Demon Slayer storyline, most of the stories take place around Edo, and also in Edo Castle itself.

If that's the case, then it means that there are actually a lot of demons around Taiichi, and even Muzan may not be far from him.

Although he hadn't seen Doma's stats, Taichi could roughly guess, based on his encounters with several demons, that Doma's strength was at least two or three times greater than Gyutaro's.

And Muzan, who is even more powerful than him, how much would his data have to inflate?

Perhaps only the Bodhisattva Samantabhadra of Paradise—Lotus—can rival him.

One is a vegetable who has been cultivating Qi for nearly 2000 years, and the other is the progenitor of demons who has eaten people for more than a thousand years.

In this crossover anime world, if Ren really came to the mainland, he planned to turn all the creatures of the Cherry Blossom Country into flowers to collect their essence.

Muzan's expression at that time will definitely be very interesting. If the two of them start arguing, the scene will be quite something.

Imagining a scene of a vegetable battling cannibals, Taiyi unknowingly found himself in Fuzhi's room.

As soon as you enter, you can smell a strong medicinal fragrance.

"My dear DouDou FuZhi, why don't you just help me refine medicine from now on? The taste is so much better than yours before!"

Taiyi walked to the wooden experimental table, picked up a pill from the plate, held it up in front of him with a strong herbal aroma, and said with a smile.

"Come on, Brother Taiyi, I would like to, but the success rate of the pills you asked me to make is just too low. I'm embarrassed to waste so many of your precious ingredients."

Fu Zhi looked at the charred waste in the other trash can and said.

When Tai handed him the things a couple of days ago, it really startled him.

Ginseng, Ganoderma lucidum, Polygonum multiflorum, deer antler and other precious medicinal materials that are highly nourishing.

Then I told him that he could make these things into pills and he could use his own methods, but he absolutely could not mix human tissue into them.

This really put Fu Zhi in a difficult position. His specialty was making human gallbladder pills, but this was the first time he had ever refined a pure Chinese medicine pill.

"Alright, if the finished product is this low, then there's no point in refining it..." Tai said, popping a pill into his mouth. He was also heartbroken about wasting so much.

But as soon as the pill entered his mouth, his eyes suddenly widened a few seconds later.

[Essence +5]

Is it real? Shall we try dropping another one?

[Essence +5]

I rely on!

Taiyi took two steps to Fuzhi's side, put his hands under Fuzhi's armpits, and lifted him up in a circle.

"Brother Taiyi, Brother Taiyi, what are you doing? I'm not a child anymore! Quick, put me down! I'm afraid of heights!"

Fu Zhi's eyes turned into the shape of mosquito coils as he experienced being lifted high in the air again after many years.

"Refine it! You absolutely must refine it! This thing could save your lives!"

Taiichi said, his eyes shining.

Now, I don't have to worry about the problem of my blood and qi increasing too quickly for the time being.

It can also provide substantial help to Zoche and others.

Especially Fu Zhi, who was slashed by Shu Jian in the original story while protecting Jianlong.

He could have saved himself, but in order to save Jianlong, he transferred all his remaining energy to him, which led to the exhaustion of his essence and his immediate death.

Furthermore, if this medicine is given to Zochi and the others that Taiichi cares about before they even land on the island, their strength will be greatly enhanced.

He had also considered whether to teach the breathing techniques to Zorche and the others.

However, considering their own strength, the imperfections of their cultivation system, and certain ideas deeply rooted in their minds in this era, they were still influenced by these factors.

In the end, he temporarily abandoned the idea of ​​teaching breathing techniques.

"I'll help you solve the problem of low yield. Then you'll have a capable assistant by your side, who is also an expert in drug research."

Taiyi narrowed his eyes and said softly.

"Huh? Do such people really exist? In Edo, there's probably only a medical clinic in Sakuma-cho, Kanda, that has such doctors, but they're very hard to find."

Fu Zhi thought for a moment, then spoke seriously.

"I don't need to go there. I don't want to come into contact with the imperial physicians or anything like that. I'm talking about someone else, someone who can't stand the light of day."

"Let's leave it at that for now. There's no rush to find someone. I'll find them for you once I return from the Okayama Domain in the Bizen region."

After Taiyi finished speaking, he wrapped the remaining pills in paper and said goodbye to Fuzhi.

"Brother Taiyi, are you going out again this time? What are you going to do?"

"While we're at it, we'll wipe out a cult, and eventually capture a monster."

Taiyi, with his back to Fuzhi, said calmly.
