Reincarnation as Lower Rank Five in Demon Slayer

After Li Lei finished speaking, the hand that held the Half-Heavenly Dog's main body, Zeng Potian, which was piercing through the Half-Heavenly Dog's clone, suddenly exerted force.

With a few cracking sounds, the Half-Heavenly Dog's true form was crushed to pieces by Li Lei and then absorbed by his palm.

Wind the string four and a half tengu - die!

The turn of events came too quickly; Bantiangou's death was quite unexpected, and Yiyong was a little slow to process it.

The demons are fighting amongst themselves, isn't Muzan going to do anything about it?

Yi Yong quickly shook his head. It was outrageous that he was thinking about such things at a time like this.

"Hmm—the Upper Moon's power is really impressive."

After absorbing the Half-Heaven Dog, Li Lei felt his power had increased again.

"Don't just watch, Mr. Kokushibo, come on—let me have a match."

Confident in his own strength, Li Lei extended a challenge to Kokushibo.

Upon hearing Li Lei's words, Kokushibo was immediately tempted, but remembering that he still had a mission assigned by Muzan-sama to complete, his newly ignited fighting spirit was instantly extinguished.

"I don't have time today, let's do it another day."

Kokushibo immediately declined Li Lei's invitation and then looked in the direction where Tanjuro was.

Noticing Kokushibo's gaze, Tanjuro immediately became highly focused.

Suddenly, Kokushibo's body moved slightly and vanished from his spot in an instant, appearing in front of Tanjuro in the blink of an eye, raising his sword to strike.

Tanjuro, who had been prepared all along, immediately used his incomplete Sun Breathing technique and raised his axe to block.

With a snap, Tanjuro's thick iron axe was cleaved in two by Kokushibo. Taking advantage of the moment the axe blocked the attack, Tanjuro immediately dodged.

Kokushibo, whose first strike failed, immediately swung his sword again. This time, the sword was as fast as lightning, slicing through the air with a whooshing sound.

The blade aimed straight for Tanjuro's chest, determined to cut him in two.

"It's over! There's no escaping it now."

A gap of several hundred years cannot be bridged simply by learning the Sun Breathing technique, especially since Tanjuro's Sun Breathing method is an incomplete version.

Just when Tanjuro was in dire straits and his life was in danger, Li Lei finally intervened.

With a loud bang, Li Lei blocked Hei Si Mu Jin's powerful and heavy slash with one hand.

"What are you doing, Lei? Why are you saving this man who knows the Sun Breathing Technique? Don't you know that the Sun Breathing Technique is very effective against us demons?"

Seeing Li Lei standing in front of Tanjuro, Kokushibo was furious.

"I know, but it's precisely because I know that we must save them."

Li Lei replied with a firm look in his eyes.

"Since that's the case, then I'll cut you down too, so you'll learn a lesson: Lord Muzan's favoritism isn't unlimited."

As he spoke, Kokushibo unleashed his full Moon Breathing, his entire body exuding a sharp aura. The katana in his hand, made from his own flesh and blood, also extended five meters in length.

"Breath of the Moon - Open"

Following closely behind, Li Lei also used the breathing technique he had learned from Kokushimona.

Li Lei's body emitted the same breathing rhythm and frequency as Heishi Mu.

Kokushibo: "Fight!"

Li Lei: "Come on!"

As if by prior arrangement, Kokushibo and Li Lei moved at the same time, each wielding their weapons and slashing at the other. With a loud bang, the blades clashed, sending sparks flying.

Then came the flashing of swords and the clanging of clashing blades.

Tanjuro watched as the two moved to the places where they had fought, and everything from rocks and trees to weeds was pulverized by the aftershocks.

Meanwhile, in Tanjiro's eyes, who was searching for his sister Nezuko in the ruins of a house, the only thing that appeared in the scene between Li Lei and Kokushibo was a series of afterimages from their collisions.

During his fight with Kokushibo, Li Lei suffered repeated knife wounds that healed immediately.

In contrast, Kokushibo rarely gets injured.

"No, I can become even better and stronger!"

Li Lei, who was constantly improving during the battles, felt a strong desire to become even stronger.

"The Crimson Eyes of the Other Shore—Open"

Having cured Kanae's eyes, Li Lei, who knew the principle of eye opening, immediately replicated it in his own eyes.

Unlike Muzan, who became the new Demon King, his physical recovery was unmatched by any other demon besides Muzan. He was completely unafraid of the secret technique that would cause Kanae to lose her sight.

Open it whenever you want, don't be afraid of the energy consumption.

Instantly, Li Lei's eyes became bloodshot, and the whites of his eyes turned blood red.

At this moment, Li Lei's dynamic vision improved to a new level, and Heishibo's sword swings became crystal clear after Li Lei opened his eyes.
