The Heavens: One World, One Superpower

He returned the Nichirin Blade to Urokodaki Sakonji.

The latter asked, "You performed very well in this battle. I didn't expect that you could apply the Water Breathing Sword Technique in actual combat so quickly after only learning it. It seems that you are really suited to be a swordsman."

Su Chen said, "Mr. Linlong's teaching is excellent."

Urokodaki Sakonji shook his head.

"Mr. Urokodaki, there is something I don't understand."

"you say."

"How can demons, which only devour human flesh and blood, possess ever-increasing power? We cultivate breathing techniques to harness the power of heaven and earth for our own use, yet demons, which merely consume human flesh and blood, can unleash incomparably formidable strength. I truly cannot understand this."

Urokodaki Sakonji shook his head and said, "That's not how it is. The ordinary demon you killed replenished its energy from human flesh and blood, that's undeniable. But its fundamental source of energy is Kibutsuji Muzan, it's Kibutsuji Muzan's blood that gave it its power."

"According to the Demon Slayer Corps' thousand-year research, demons also absorb energy from heaven and earth, but this energy is the evil energy that exists in heaven and earth. We Demon Slayer Corps members absorb the righteous energy of heaven and earth."

"Ordinary demons, like the one you killed, cannot absorb the evil energy of heaven and earth. Therefore, they can only cultivate the evil energy inherent in Muzan Kibutsuji's blood by devouring flesh and blood, so their power increase is limited."

"But some demons, such as Muzan Kibutsuji himself, the Lower and Upper Moon demons of the Twelve Demon Moons, and demons who know Blood Demon Arts, can absorb evil energy from the world to replenish themselves."

"Blood Demon Art and our breathing techniques are essentially the same."

"We can exchange energy between heaven and earth; they exchange evil energy, while we exchange righteous energy."

"As for how they exchanged them, that remains a mystery that has puzzled the Demon Slayer Corps for a thousand years."

"These ordinary demons are like ordinary members of the Demon Slayer Corps. They can't master breathing techniques, so they can only do some simple logistical work. Ordinary demons can't absorb the evil energy between heaven and earth, so they can only increase their strength by devouring flesh and blood."

"Powerful demons do not increase their strength by devouring human flesh and blood; they simply have a natural inclination to drink blood and eat flesh. They increase their strength by absorbing the evil energy of heaven and earth."

Su Chen was shocked upon hearing this.

I never imagined that evil spirits could also possess the ability to absorb the power of heaven and earth.

This is absolutely outrageous.

Urokodaki Sakonji looked at Kamado Tanjiro.

The latter was listening attentively.

Tanjiro realized that the old man in front of him was the teacher that Giyu Tomioka had asked him to find.

The Su Chen before them was also a swordsman who had become a disciple of the old man.

"You're Tanjiro Kamado?"

"It is indeed me. I have met Mr. Urokodaki before. She is my younger sister, Kamado Nezuko," Tanjiro said, pointing to Nezuko.

"I'm asking you, if one day your sister ate people, what would you do?"

Urokodaki Sakonji's voice was calm and indifferent.

Like a hammer, it slammed into Tanjiro's heart.

eat human?

Tanjiro is now caught in a moral dilemma.

In his heart, he couldn't be 100% sure that Ni Douzi wouldn't be attracted to flesh and blood.

After all, she had only been a ghost for three days.

What can you learn in three days?

That's why Tanjiro is in such a dilemma.

He can't guarantee anything.

They also knew that eating flesh and blood from the Beans would harm humans.

But that's his sister. He simply couldn't bring himself to say anything about killing Mizuko.

The only responsibility of an older brother is to protect his younger sister.

Instead of killing her.

A hint of anger flashed in Urokodaki Sakonji's calm eyes.

He stepped forward and slapped Tanjiro hard across the face.

He angrily retorted, "Your answer is too slow. Your weakness is obvious: indecisiveness."

"He exudes an aura of indecisiveness."

"Why couldn't you answer the question immediately?"

"It's because you lack awareness."

"If your sister eats someone, you only have two things to do: kill your sister, and then commit seppuku."

"If you're going to take care of your sister who's turned into a demon, you have to be prepared for that."

"But remember this well."

"This kind of thing absolutely cannot happen."

"We cannot let your sister take the lives of innocent people."

Do you understand what I mean?

The last sentence was gentle and calm, devoid of any anger.

In Su Chen's view, this was to establish Tanjiro's ideological foundation.

To become a Demon Slayer, one must have a clear mindset.

They also protect their younger sister with clear intentions, including ordinary people who are persecuted by evil spirits.

Tanjiro understands this.

He could sense it from the aura emanating from Urokodaki Sakonji.

Isn't this teacher in front of me a kind person?

He exudes an aura of kindness.

He nodded emphatically and said, "I understand."

"If my sister ate someone, it would be a sin I committed, a seed of disaster I planted. I will definitely do everything right."

He looked at the beans.

There is endless pain in my heart.

He hated his own incompetence.

I couldn't save my father, who passed away from a serious illness six months ago.

Three days ago, I couldn't save my mother, brother, and sister who were slaughtered by evil spirits.

There's no way to save my sister now that she's become a ghost.

At the same time, they made up their minds.

"I want to become a powerful swordsman, participate in the extermination of demons, and find a way to turn Nezuko back into a human."

"At the same time, I won't let my sister eat people."

"I believe she wouldn't eat people."

He made a silent vow in his heart.

Urokodaki Sakonji immediately sensed the aura emanating from Tanjiro.

That was the aura of unwavering will.

He couldn't help but secretly agree.

The three buried the remaining remains.

The temple was a scene of bloodshed.

Su Chen covered it with pure white snow.

Soon, three more grave mounds appeared in the courtyard.

Urokodaki Sakonji sighed.

As long as evil spirits are not eliminated, ordinary people in the world will suffer harm every day.

He looked at Su Chen and said, "Xiao Chen, take Tanjiro and Nezuko back to Mount Sagiri."

Su Chen nodded.

Just then, Urokodaki Sakonji disappeared again in an instant.

The speed is so fast that I am always amazed whenever I see it.

He looked at Tanjiro.

The boy is sunny, gentle, and determined.

"My name is Su Chen, you can call me Brother Chen from now on."

"Brother Chen."

"I have something to tell you. Mr. Urokodaki and Senior Brother Giyu have taken in your sister, Mizuko. Once she starts eating people, the two of them will commit seppuku to atone for their sins."

Tanjiro was shocked.

I felt an overwhelming sense of gratitude and guilt.

"They've been implicated because of what happened to me."

"There's no need for that. Like them, I firmly believe that Nezuko wouldn't eat people; she possesses humanity. Humanity can overcome demonic nature, which is the fundamental reason why the Demon Slayer Corps has been able to persist in fighting demons for thousands of years. Let's go to Mount Sagiri. You will receive training there and become a qualified swordsman. Only then will you have the ability to protect Nezuko."

Su Chen led Tanjiro and Nezuko toward Mt. Sagiri.
