Comprehensive Manga: Starting from the Soul Society and cutting through all the worlds

Because he was in the Demon Slayer Corps, Yecheng could see many members of the Demon Slayer Corps exercising every day.

In particular, because Yecheng admired him and owed him a favor, Yecheng asked Urokodaki and Rengoku to show him the Water Breathing and Flame Breathing.

As two of the five basic breathing methods, the breathing methods they showed also gave Yecheng more inspiration.

The so-called "breathing method" is actually a combat auxiliary method.

It is a technique that can enhance physical ability to fight against demons whose physical ability is far stronger than that of humans, collectively known as "full-concentrated breathing".

The principle is to strengthen the heart and lung function, so that the blood can absorb a large amount of oxygen in a short period of time, which can greatly increase the physical ability in an instant, and then temporarily have the same physical strength as the demon.

The higher level of full-concentrated breathing is "full-concentration constant", which can continue to concentrate on breathing even when sleeping.

The frequencies and methods of various breathing methods are different, so various schools are formed, and various moves that match breathing have appeared.

Ye Cheng is a swordsman. After mastering the principle of breathing, he quickly got to the point.

And unlike ordinary people, people in this world rely on the large amount of oxygen produced by breathing to strengthen their heart and lung function and improve their physical fitness.

But Ye Cheng's breathing method does not rely on oxygen, but on his unique spiritual power!

Yes, although after coming to this world, Ye Cheng found that he had changed from a spirit to a physical body, he still had spiritual power, which is beyond doubt.

Since they are all strengthening their own heart and lung function, why not use more powerful spiritual power directly than the oxygen that is everywhere?

When trying at the beginning, Ye Cheng, who was crossing the river by feeling the stones, was undoubtedly blocked everywhere, and even almost killed himself several times.

Because the internal organs of the human body are very fragile, the idea of ​​"spiritual breathing method" is not a problem, but compared with oxygen, spiritual power is obviously more domineering.

Before adapting and mastering the rhythm of breathing, Ye Cheng almost died because of internal organ rupture.

But fortunately, his physique is different from that of ordinary people, so after several attempts at death, he finally got started with the "Spirit Breathing Method".

Even when Ye Cheng completed a complete breath for the first time, the entire Demon Slayer Corps was shocked.

Because compared to other people, the movement caused by Ye Cheng's breathing method was too amazing!

The air in the Demon Slayer world contains spirit particles, but they are quite weak and cannot be compared with the world of death.

In order to absorb all the spirit particles around him into the body through breathing, Ye Cheng's breathing movement is naturally quite amazing!

Other people's breathing methods, with a little more movement, at most, just spray out a burst of white mist.

And Ye Cheng's full concentration breathing is like a whale swallowing, directly making the environment within one meter around him like a vacuum!

It's the same breathing method, but if Ye Cheng's breathing method is stronger, other breathing methods will not even have room to be used around him.

The reason is very simple. All the oxygen around Yecheng has been sucked into a vacuum. How can you use breathing techniques to strengthen your heart and lungs and enhance your physical fitness?

When seeing the noise caused by Yecheng's breathing technique, Urokura and Rengoku looked at each other in silence.

When Yecheng asked them about breathing techniques before, they guessed that Yecheng might want to study breathing techniques.

But they didn't expect that Yecheng would create a breathing technique suitable for himself so quickly, and they all knew that this breathing technique was quite amazing just by looking at the momentum.

In their eyes, Yecheng had always been a "genius", but now it seems that they still underestimated the degree of his perversion.

This guy is not a genius at all, this guy is a complete monster!

Although the people of the Demon Slayer Corps don't know what breathing technique Yecheng has mastered, they can be sure that the breathing technique Yecheng has mastered is quite good, and it is not any existing breathing technique.

After all, among the known breathing techniques, none of them can cause such a big noise like Yecheng.

One month after Ye Cheng mastered the breathing method, he was promoted from a member of the Demon Slayer Corps to one of the Court Pillars.

And all this was as natural as water flowing into the river. Even when Ubuyashiki Yoya proposed this matter, no one in the Demon Slayer Corps or even the Court Pillars objected.

Hiruzen Fujikiyama Chiki, and solved all the targets of the Demon Slayer Corps in three days, and even killed three of the twelve demon moons. These achievements are enough to prove Ye Cheng's strength.

After that, in less than a week, he created his own breathing method, which fully proved Ye Cheng's talent.

Not only is he powerful, but he is also very talented, and he is so young that even the senior Water Pillar and Flame Pillar strongly recommend him. Naturally, there will be no obstacles for Ye Cheng to become one of the Court Pillars.

Because of this, Ye Cheng directly set the fastest record of becoming a pillar in history.

Because from the time he joined the Demon Slayer Corps to the time he became one of the Court Pillars, it took less than half a month, and he completed the fastest promotion record in history.

After Yoshiro became the "Spirit Pillar", Urokodaki felt that he was no longer mentally capable of continuing to be one of the Court Pillars because of the incident with the Hand Ghost, so he retired. Not long after, Tomioka Giyuu succeeded him as the Water Pillar.

Two years passed quickly afterwards, and Ye Cheng also gradually became famous in the Demon Slayer Corps from being unknown, and even had a brief contact with the big boss Muzan Kibutsuji.

To be more precise, it should be Muzan Kibutsuji who took the initiative to find Ye Cheng.

The tragic deaths of the twelve demon moons in a short period of time attracted Muzan Kibutsuji's attention.

Although the waning moons often changed in batches compared to the waxing moons, they were still senior brothers who he personally gave power to. Now that they were said by the same person in a short period of time, Muzan Kibutsuji would naturally feel strange.

So through various clues, Muzan Kibutsuji quickly found the village where Ye Cheng was staying, and saw Ye Cheng playing with children from a distance.

Muzan Kibutsuji himself did not expect that he had been discovered by the other party just by spying from a distance.

And at the moment when Ye Cheng looked at him, Muzan Kibutsuji actually felt the threat of death for the second time in thousands of years!

The other party did nothing, but Muzan Kibutsuji felt like he was falling into an ice cellar, and this feeling was not the first time he had experienced it...

He had felt the same feeling and danger from a man named Tsugumi Yoriichi, and now, after many years, the second guy who made Muzan Kibutsuji feel dangerous appeared in this world again!
