Reincarnation as Lower Rank Five in Demon Slayer

In the Infinity Castle, on a vast open space, Muzan was suddenly teleported to the scene. He was terrified and somewhat bewildered, and quickly scanned his surroundings with his eyes.

He noticed Li Lei watching him quietly from a short distance away and immediately sensed something was wrong.

"Tired? What do you want? Don't forget that I gave you this immortal body so you wouldn't die from illness. Are you going to repay kindness with enmity?"

Seeing that Li Lei remained unmoved, Wu Can and the others quickly began to think.

"I know you're a good kid, listen to me! Open the Infinite City and let me out. I won't interfere with what you do from now on, you can do whatever you want."

Muzan was in a panic. Although he felt that Li Lei's power was only one-tenth of his own, he should have won the life-or-death battle.

However, back then, Yoriichi was much weaker than Li Lei in front of him, like an ordinary person, yet he still managed to slice him into pieces in a single encounter.

Back then, he couldn't even see Yoriichi's shadow clearly, let alone this demon in front of him who knew the Sun Breathing Technique and whose body was far superior to that of an ordinary person.

He really wants to slap his past self now. Why did he turn exhaustion into a ghost for no reason, just because his physical condition is somewhat similar to when he was still human?

At this moment, Muzan was filled with regret, wondering why he had acted so impulsively.

"Lord Muzan, are you afraid? Actually, you don't need to be afraid. I remember all the kindness you've shown me. Out of consideration for past favors, I won't kill you today."

Seeing Muzan at a loss, trying to think of a solution, Li Lei finally spoke up.

"What about tomorrow, the day after tomorrow, and from then on?"

Fearing that Li Lei's words might have a hidden meaning, Muzan immediately pressed for an answer.

"Neither will it."

Li Lei gave a firm reply.

"Then just open the Infinite City and let me out, why did you teleport me here?"

Muzan was puzzled and immediately wanted to ask for clarification.

"There are two reasons. First, Lord Muzan, don't you want to overcome the sunlight?"

"You're still willing to help me even when I'm tired."

Muzan looked at Li Lei with unwavering confidence, thinking that if he were to overcome the sunlight, he could wipe out all the other demons with a single thought.

He would never even consider turning his subordinates into ghosts who can overcome sunlight.

"Lord Muzan, don't worry, there's a second reason."

"Lord Muzan, you are too strong as a demon. You must relinquish your throne and power as the Demon King so that I can make you a demon who can overcome sunlight."

Li Lei slowly stated his requirements.

"That's impossible. How can I live without power? Besides, you might not keep your word."

Upon hearing Li Lei's request, Muzan immediately refused.

"Lord Muzan, you seem to have misunderstood something. This is not a choice for you, but a choice you must make. If you don't choose, I will help you."

Seeing that Muzan disagreed, Li Lei was about to resort to violence. Today, Muzan only had one choice: either you agree yourself, or I'll use reason to make you agree.

"You ungrateful bastard! I treated you so well before, and now that you've grown up, you not only don't listen to me, but you also want to destroy me. I'll fight you to the death!"

Enraged, Muzan charged at Li Lei, determined to fight this traitor to the death.

"That's exactly what I meant."

Li Lei took out the last Nichirin Blade from his collection in his alternate dimension. He first used the Breath of the Sun, then used the Blood Demon Art: Blood Flame to enchant the Nichirin Blade in his hand. He then continuously applied force to his hand, activating the Crimson Blade.

While using the Breath of the Sun, Li Lei kept pushing his heart beyond its limit, his blood flowing rapidly throughout his body. Soon, Li Lei's body temperature rose again, and several flame-like patterns appeared all over his body.

“Now I lack nothing.” Li Lei uttered the Holy Lord’s profound words.

With a powerful demon body capable of acquiring countless Blood Demon Arts and having overcome sunlight, possessing the world's strongest Sun Breathing technique, the Transparent World, the Crimson Blade, and the Yoriichi-style mark, Li Lei is a terrifying combination of the strongest skills from Demon Slayer.

It can be said that even if Yoriichi, who once instantly killed Muzan, were to reappear, he wouldn't be able to do much against Li Lei now.

When Muzan saw Li Lei's fully upgraded divine equipment, he immediately realized that he had acted impulsively in his heat of the moment, and now it was too late to regret it.

You can't go head-to-head with a tired person; if you do, they'll break.

The word "escape" immediately popped into Muzan's mind. As the saying goes, "Where there's life, there's hope," and "A wise man doesn't suffer a loss he can't avoid."

Muzan immediately abandoned the idea of ​​competing with Li Lei.

In an instant, Muzan used the same trick again, his body exploding into thousands of pieces of flesh that scattered in all directions.

Seeing this, Li Lei, who already had a plan, activated the Blood Demon Art he obtained from Arrow Demon, and immediately used gravity to pull all of Muzan's fleeing chunks of flesh towards him.

Muzan: It's over (┳Д┳) I can't escape this either.

With a look of unwavering determination, Li Lei devoured every last piece of Muzan's flesh that had been sucked in.

From then on, Li Lei became the new Demon King. Then, through the Demon King's absolute power over the life and death of other demons, Li Lei recovered all the blood that Muzan had distributed. In the process, Li Lei also obtained many different kinds of Blood Demon Techniques.

In the vast, boundless city, on a brightly lit platform, Li Lei took out a fleshy ball the size of a thumb from his body and threw it in the center of the platform. As soon as the fleshy ball touched the ground, it rapidly expanded and instantly grew into the shape of a very beautiful woman.

"Congratulations, Lord Muzan, you've been reborn! Are you satisfied with the immortal body I created for you, the one that's immune to sunlight? It looks exactly like your previous female appearance."

Li Lei's eyes darted around, scrutinizing Muzan's new body, and he kept making sounds of admiration.

As expected of a body he sculpted himself, its proportions are perfect.

Muzan felt his body was now so weak and frail, utterly powerless. Most importantly, this body was unable to absorb any nutrients from flesh and blood.

Muzan knew this was a death order Li Lei had given to all the cells in this body. Clearly, Li Lei didn't want him to eat people to become stronger.

"I'm tired! Why did you give me a female body? And I'm not even dressed." Muzan voiced the question that was on his mind.

"I used to see Lord Muzan transformed into a woman quite often, and I thought you liked it. As for the clothes, of course I didn't know what kind of clothes Muzan liked, so I didn't transform them for you."

Li Lei explained casually.

After hearing Li Lei's explanation, Muzan, who had lived for over a thousand years, was speechless. He knew without even thinking that Li Lei had done it on purpose.

"Alright, Lord Muzan, go and enjoy your life after overcoming the sunlight."

Not wanting to say anything more, Li Lei casually tossed a few sets of clothes to Muzan, then used the Blood Demon Art he obtained from Nakime to throw Muzan out of the Infinity Castle, landing him right on the bed of Demon Slayer Corps leader Kaguya.

"Damn it, who are you? Why are you naked?"

Seeing the woman suddenly appear in mid-air, Hui Yaozai almost broke out in a cold sweat.

"Wait, you're Muzan!"

Once his mind calmed down and he came to his senses, Huiyao Zai instinctively recognized Muzan instantly.

Muzan's face flushed crimson; he felt utterly humiliated. He'd rather she were dead.

In the infinite city of another dimension, in a very luxurious room, on an enormous, obviously expensive bed, Li Lei, with women on his left and right, looked at a mirror in the air in front of him and laughed incessantly.

The ultra-high-definition image in the mirror shows Muzan, now a woman, falling onto the Radiant Bed.

"Hahaha, Moka-nee, Kanae, look, Muzan's blushing face is so funny."

Kanae and Amane Moka looked at Li Lei, who was almost indistinguishable from a god, and were at a loss for words when they saw his strange hobby.

How could I have ever fallen for him? This bastard is always looking for trouble with the Demon Slayer Corps.

This is the umpteenth time this month, and they can't even imagine how many more people will suffer.
