Reincarnation as Lower Rank Five in Demon Slayer

"I'm doing very well, Lord Muzan. After becoming a demon, I no longer live as weak and helpless as before. Now I can do what I like, and just as Lord Muzan said, weak creatures like humans cannot understand the powerful like us."

Muzan smiled and said, "Tired? I wasn't wrong about you. You are indeed very suitable to be a demon."

"It is an honor for Rui to receive Lord Muzan's praise."

"I'm glad that you were able to defeat and absorb Lower Moon Six in just a few months after becoming a demon."

"Since the Fifth Lower Moon was recently killed by a demon slayer, I hereby appoint you as the Fifth Lower Moon."

When Li Lei heard Muzan appoint him as the fifth Lower Moon, he felt a change in his left eye.

Li Lei didn't need to look to know that the unique number of the Lower Rank Demon among the Twelve Demons had appeared in his left eye, and his own number was Lower Rank 5.

Faced with the changes in his left eye, Li Lei felt as if he could stop the changes, and even break free from Muzan's control at any time. This seemed to be related to his unique parasitic blood demon technique.

Li Lei, who sensed that he could break free from Muzan's control at any time, did not make any small moves in order to confuse Muzan and let him know that he was always under Muzan's control and had no possibility of escaping.

"Thank you for your recognition, Lord Muzan. Rui will definitely become an Upper Moon and help Lord Muzan."

"bump--"

As Nakime's zither music filled the air, a table instantly appeared in front of Li Lei, with a bowl of Muzan's blood on it, clearly something that had been prepared beforehand.

"Tired? Drink this bowl of the blood I've given you, and become stronger!"

Li Lei looked at the blood of Muzan that appeared before him, and respectfully said to Muzan: "Thank you for your reward, Lord Muzan."

After thanking Muzan, Li Lei went straight to the table and picked up the bowl containing Muzan's blood.

Looking at the bright red blood in the bowl, Li Lei expressionlessly raised his hand and gulped it down.

Li Lei calmly put down the bowl in his hand, but suddenly his heart started pounding. He immediately bent forward and began to pant heavily.

I could feel my Blood Demon Art and physical body rapidly becoming stronger, but after a few minutes, the growth stopped.

Li Lei straightened up and carefully felt his body after becoming stronger. Among them, the Blood Demon Technique had changed the most, with a qualitative leap, and his body had become several times stronger.

Even now, among the current Pillars of the Demon Slayer Corps, none of them can match me in a one-on-one fight.

Muzan was very pleased to see that Muzan was quickly adapting to the fatigue of his own blood.

"I'm tired. I have things to do. You can wander around the Infinite Castle by yourself. If you want to leave, just let Nakime know."

"Understood, Lord Muzan!"

"bump--"

The sound of a zither drifted over, and Muzan, who had just been in front of Li Lei, was now teleported away.

After Muzan left, Li Lei wandered aimlessly through the vast and empty Infinite Castle.

As Li Lei walked, he somehow ended up on a long but winding staircase.

As Li Lei walked up the stairs, he looked at the enormous city, but devoid of any human presence, and thought to himself:

"Nakome's Blood Demon Art is too exaggerated! Other people's Blood Demon Art has all sorts of strange abilities, but although they are strange, they are mostly related to the strength of their master."

"But Nakime's Blood Demon Art doesn't seem to have much to do with her strength, which is very strange. Her Blood Demon Art is terrifyingly powerful, but her own strength isn't even up to the level of an Upper Moon, no! Or even lower than a Lower Moon."

Why do I say this? Because in the original story, Nakime was controlled by Yushiro, who couldn't even defeat a Lower Moon.

This is ridiculous. Despite possessing the excessively powerful Blood Demon Art of the Infinite City of Another Dimension, his own strength is unimaginably weak.

If Nakime's Blood Demon Art is related to her strength, there are two possibilities. One is that due to the influence of her strength, the Blood Demon Art Infinite Castle might only be the size of a village with a few dozen people.

The other possibility is an exaggeration! Due to the influence of the Blood Demon Art, its strength would become terrifying. That would be the strongest demon besides Muzan, Upper Moon One, and the demonized Tanjiro.

In my past life, when I watched Demon Slayer, I was very curious about Nakime's Blood Demon Art. Why is the space created by Nakime's Blood Demon Art so large? How did she manage to do that?

Forget it! I don't want to think about it anymore.

Li Lei shook his head. He'd rather explore this Infinite City some more. What fun things could he possibly find?

Li Lei looked up and around at the space where there were houses all around him.

"Infinite City is really big!"

Wait a minute? The Infinite City is huge, and it's impossible to distinguish up from down from left from right from right! Plus, there's my own Thread Blood Demon Art.

Hmm! Does that mean I'm going to become Spider-Man?!

The thought of swinging between houses like Spider-Man on his webs filled Li Lei with excitement.

After calming down, Li Lei looked up at the upside-down houses in front of him and took a deep breath.

Raise your right hand, palm facing upwards towards the house, and immediately activate the Silk Thread Blood Demon Technique. Instantly, a silk thread shoots out from your palm and grabs the house in front of you in a flash.

Li Lei grabbed the silk thread with both hands, pulled hard, and jumped forward with his back foot. Instantly, Li Lei swung forward like Spider-Man.

At the highest point of the swing, he immediately used his left hand to repeat the same method as his right hand, shooting out threads and swinging back and forth in the Infinite City. Li Lei had a great time.

With a snap, Li Lei stopped on a wooden platform. The reason was that while playing on the swing in the Infinite City, he had thought of another use for the Silk Thread Blood Demon Technique.

Li Lei stood on the platform with his eyes closed, motionless, sensing and controlling his Blood Demon Thread Technique. After several tens of minutes, Li Lei suddenly opened his eyes.

"Silk Thread Blood Demon Art - Blood Rain"

In the blink of an eye, countless crimson threads shot out from Li Lei's pores, piercing through a dense network of crimson threads within a fifty-meter radius around him. It was clear that Li Lei's attack was a wide-range assault.

Li Lei looked at the area damaged by his blood-stained rain and was quite satisfied.

"Narukae!" Li Lei shouted.

"bump--"

Then came the sound of a zither, and Nakime used Blood Demon Art to teleport to a spot not far from Li Lei.

Looking at Nakime who had been teleported out, Li Lei smiled and said to her: Nakime, your Blood Demon Art is really powerful! This is the first time I've ever heard of a Blood Demon Art that can create an alternate dimension as large as the Infinite Castle!

Nakime looked at Li Lei expressionlessly and asked, "So, is there something you need? Don't call me unless there's nothing wrong!"

Li Lei looked at Mingnu, who seemed to ignore him, and wondered: What's wrong? I don't think I did anything to upset her! Could it be that she's still doing *that* thing after I became a ghost?

Unable to understand, Li Lei calmly said: "Naruki! Take me back to where I was."

Hearing Li Lei say he wanted to go back, Mingnu didn't ask any questions. She simply plucked a string from her zither.

"bump--"

The sound of the zither echoed in Li Lei's ears, and in the blink of an eye, Li Lei had been teleported out of the infinite city of the alternate dimension.

Meanwhile, where Li Lei had left, Xiao Wu and Xiao Hei were staring at each other blankly. Suddenly, a door appeared in the open space next to them, opened, and Li Lei walked out.

Xiao Wu and Xiao Hei were overjoyed to see Li Lei appear and exclaimed, "Master, you're back!"

And immediately ran over and hugged Li Lei's big legs.

Li Lei didn't notice Xiao Wu and Xiao Hei clinging to his legs because he was still wondering why Ming Nu ignored him.
