The Heavens: One World, One Superpower

"Therefore, the intensity of breathing techniques is not only related to the user's physical fitness, but also deeply tied to the user's state of mind and willpower."

"Different states of mind and willpower lead to different experiences of the power of heaven and earth."

"In turn, it can unleash different kinds of power."

"Although the forces of heaven and earth vary greatly, and the breath of heaven and earth is complex and diverse, they are all essentially infinite and without end."

"As long as you delve deeper, you will definitely be able to unleash the power that suits you best, and thus create your own sword style."

As he said this, he couldn't help but show an expression of admiration, praise, and satisfaction.

He thought of his disciple, Yoshiyuki Tomioka.

What an exceptionally talented swordsman he was.

At the age of twenty, he became a modern-day water column.

And they found a suitable source of power from heaven and earth for themselves.

To advance the breathing technique to an extremely profound level.

This led to the development of Water Breathing, Form 11: Nagi.

With this sword shape, one can enter a special state, forming an absolute defensive circle around oneself with the sword as the axis.

This is an overwhelming defensive capability.

He continued, "For example, your senior brother, Giyu Tomioka, found the most suitable source of breathing for himself and developed the eleventh form of Water Breathing."

"You will meet him later, and you can have a good talk with him and learn the essence of his unique breathing techniques."

Su Chen could sense it.

Urokodaki Sakonji was extremely satisfied with Tomioka Giyuu.

He was almost his most outstanding disciple in decades.

It is something to be proud of.

This conversation gave him a certain understanding of the true essence of breathing techniques.

It turns out that breathing techniques are a method for achieving harmony between humanity and nature.

Using its own body as a support, it exerts the power of heaven and earth.

At the same time, it is also closely related to a person's physique, willpower, and state of mind.

The breath of heaven and earth is complex and multifaceted; only certain types of people can resonate with certain types of the power of heaven and earth.

Only by finding the right source of energy from heaven and earth can one fully utilize the power of breathing techniques.

Urokodaki Sakonji then explained the origins of the breathing technique to Su Chen.

"The breath of heaven and earth has existed since the beginning of time."

"But to this day, humans have only mastered breathing techniques for a little over four hundred years, thanks to a remarkable person who appeared during the Warring States period."

"He was exceptionally talented, comprehending the breathing techniques from the universe, becoming the first person in the world to master them, and it is the most powerful breathing technique in the world to date. Unfortunately, his origins, deeds, and that breathing technique have been lost to the long river of time, and there are no more records of this creator of the breathing technique."

"The first breathing technique he created on earth is the source of many later breathing techniques."

"At that time, demons had already existed for over five hundred years. The progenitor of demons, Kibushi Muzan, was a human from the Heian period, and it was during that time that he became a demon for unknown reasons. After he became a demon, the Ubuyashiki family also formed the Demon Slayer Corps, vowing to kill Kibushi Muzan and rid humanity of this great scourge."

"For over five hundred years, from the Heian period to the Sengoku period, the Demon Slayer Corps lacked a Breathing Technique, relying solely on its superior swordsmanship and Nichirin Blades to combat demons. The Demon Slayer Corps was constantly oppressed by the power of demons, teetering on the brink of extinction. It wasn't until the emergence of that extraordinary person in the Sengoku period, who brought the first Breathing Technique, incorporating the power of heaven and earth into the fight against demons, that they were able to turn the tide and once pushed demons to the brink of extinction. Even the progenitor of demons, Muzan Kibutsuji, was nearly annihilated by that extraordinary person."
