Reincarnation as Lower Rank Five in Demon Slayer

Chapter 152 The Troublesome Black Shiro

"Tired? Did I hear that right? You want to learn Kokushibo's breathing techniques and swordsmanship?"

"Yes, Lord Muzan. I can sense it from his breathing. Lord Kokushibo's breathing technique is the strongest I have ever encountered. Lord Kokushibo has been a demon for a long time, so his swordsmanship must have reached an extraordinary level."

"Lord Muzan, my strength is still too weak. I want to become stronger. I want to become a demon useful to you. I want to become strong quickly so that I can share your burdens. I even want to find the Blue Spider Lily for you."

Li Lei spoke eloquently and passionately, his tone firm and impassioned, until he himself began to believe it.

"Tired—you're such a good kid, much better than the other Upper Moon demons."

"I promise you, this is called Kokushibo teaching you breathing techniques and swordsmanship."

Hearing Li Lei's words, Muzan felt gratified and immediately agreed without even thinking whether Li Lei was being sincere.

Kokushibo: "..."

Wait, aren't you even going to ask my opinion? I haven't even agreed yet. Kokushibo's face was full of speechlessness; he didn't want to say anything at the moment.

"Lord Muzan, you are so kind to me."

"You're so sensible, of course I want to treat you well."

……

An hour later, Li Lei and Muzan were still exchanging pleasantries, which Kokushibo couldn't stand any longer. He wanted to leave for a while, but before he could even get up, he was stopped by a look from Muzan.

"Can't I even get up and move around a little? Lord Muzan." Kokushibo wondered to himself as he faced Muzan.

"Just bear with it, Kokushibo." Muzan ignored Kokushibo's emotions and spoke directly to Li Lei.

Hearing this, Kokushibo felt a pang of pain in his heart. Hundreds of years of friendship, and because of this brat, he had to wait on the sidelines.

In the end, Kokushibo had no choice but to return the way he came, sit down, close his eyes to rest, and wait for Muzan and his "son" to finish their conversation.

"Ugh--"

Kokushibo let out a soft sigh. At this moment, with his eyes closed, he hadn't expected to be so bored next to Lord Muzan.

……

Time flew by, and Li Lei and Muzan finally finished their conversation.

"Alright, I'm tired. Let's call it a day. Go back and eat lots of people to get stronger as soon as possible. I have high hopes for you."

"Yes! Lord Muzan, I will."

"Great, they've finally finished talking. It's like the end of the hardship is finally over." Upon hearing this, Kokushibo immediately went from being listless to being energetic. Kokushibo couldn't wait to leave.

Just as Kokushibo was about to get up and run away, Muzan's last words instantly brought Kokushibo's emotions to zero.

"By the way, Kokushibo, after I leave, teach Rui swordsmanship and breathing techniques properly. I'll be checking up on him afterwards."

"If I find that what you're teaching him is perfunctory, you'd better prepare to replace Akaza for a long time."

Kokushibo: "..."

Muzan's last words before leaving left Kokushibo speechless. Li Lei, who was watching from the side, wanted to laugh, but having received nine years of compulsory education, he usually didn't laugh unless he couldn't help it.

→_→………?(ˊ????? ? ?????ˋ)

"This brat is so annoying. What's so good about him that Lord Muzan likes him so much?"

Seeing Li Lei's ever-growing smile, Hei Shimu's impression of Li Lei worsened. He felt that he must have committed terrible sins in his past life, otherwise, how could he have encountered such a scourge as Li Lei?

"Upper Moon One, when are we going to start learning breathing techniques? I can't wait!"

Looking at Kokushibo, Li Lei's eyes were filled with a desire to learn. If it weren't for the huge difference in strength, he would have wanted to use force to exchange the Blood Exchange Demon Technique for the Memory Demon Eye and steal it outright.

Kokushibo frowned, feeling a chill run down his spine. Could the brat in front of him be thinking bad things about him?

"Lord Kokushibo, please speak! Where shall we practice the breathing techniques and swordsmanship? Let's begin there."

Li Lei kept urging Kokushibo on. Anyway, with Muzan taking the lead, as long as he didn't go too far, Kokushibo wouldn't dare to do that to him.

"Okay, I'll teach you right now."

Facing the somewhat arrogant Li Lei, Hei Shimu suppressed his displeasure and replied.

What an annoying brat! I really want to chop him in half right now, but I can't, Muzan is still watching from afar.

Thus, Kokushibo had no choice but to teach Li Lei breathing techniques and swordsmanship in the Infinite Castle.
