I started with Demon Slayer, and after drawing the strongest character, I'm invincible!

Jiang Bubai picked up the tiny Nezuko from the stove and placed it in front of him.

He peered at Nezuko Kamado through the blindfold, and all the information gathered by the Six Eyes flooded into his head.

Ding! [Side Quest 3: Tanjiro Kamado's Wish.]

[Mission Content: After his sister became a demon, Tanjiro Kamado has been searching for a way to turn her back into a human.]

Please help this poor boy fulfill his wish and turn Nezuko Kamado back into a human.

[Mission Reward: Energy Points.]

Jiang Bubai shook the little thing in his hand again; this little thing was worth ten million energy points.

This side quest offers generous rewards, but it's also quite challenging.

Fighting and killing are no challenge for him, but he really doesn't know how to turn a ghost back into a human.

"Host, do you want to accept this mission?"

The sound of "666" echoed in Jiang Bubai's mind. His guess was correct; a side quest could indeed be triggered on Nezuko Kamado.

However, this side quest is a bit unfriendly, as the method to turn a ghost back into a human has not yet appeared in this world.

Gojo Satoru is the strongest, but this mission doesn't seem to have much to do with how strong he is.

"Come on, why wouldn't you? Don't forget, I'm the strongest."

Jiang Bubai accepted the side quest without hesitation, as he could learn anything with just five insights.

He'll study the method to turn a ghost back into a human carefully; maybe he can actually succeed.

There's no loss if he can't complete the side quests, and besides, he doesn't know how the plot of this world is going.

However, following the usual pattern, Nezuko Kamado should be able to successfully transform back into a human.

"Mr. Gojo? How is Nezuko?"

Seeing that Gojo Satoru seemed to have fallen silent, Kamado Tanjiro couldn't help but ask.

"It's alright, the power within her has mutated. Don't worry, it's mutating for the better."

Jiang Bubai put Nezuko back in her original position and discovered that there was still a strange power in Nezuko's body.

That power merged with the demonic power within her, causing her power to mutate.

It is said that all demons are controlled by the Demon King, but Nezuko Kamado is an exception, which may be related to this.

"A good direction? Really? Mr. Gojo, is it possible for Nezuko to turn back into a human?"

Tanjiro Kamado looked at Satoru Gojo with excitement, feeling that Nezuko was slowly regaining her senses.

Because Nezuko knows how to call her brother and can recognize people.

Does this mean that Nezuko will eventually return to normal?

"It's possible, but I don't know the specific method."

Jiang Bubai shook his head helplessly. He really didn't know how to turn Nezuko back into a human.

"It's okay, I will definitely try my best to find a way to turn Nezuko back into a human."

Tanjiro smiled happily; at least he knew this wasn't just wishful thinking.

Nezuko can turn back into a human, she just hasn't found the way yet.

……

"You said your Demon Slayer Corps lord invited me to be his guest?"

After Jiang Bubai came out of the infirmary that Kocho Shinobu had arranged for him, he encountered Rengoku Kyojuro.

He's been busy these past two days researching how to turn Nezuko Kamado back into a human.

For this purpose, he even asked Shinobu Kocho for an unused medical room to conduct experiments.

"That's right, Wu, would you like to go and see the lord?"

Kyojuro Rengoku's Kasugai crow has returned from the main residence of Ubuyashiki, bringing back a letter from his lord.

The letter mentioned two things: first, it invited Gojo Satoru to visit the main house; second, it called for a meeting of the Pillars.

"Okay, when are we going?"

Jiang Bubai had a vague premonition that the main quest might be about to begin.

"Great, let's set off now."

Kyojuro Rengoku is ready to depart, and they can set off as soon as Satoru Gojo agrees.

"Wait a moment, let me put my things away first."

Jiang Bubai turned around and went back into the infirmary, putting the only two test tubes inside into the system space.

The system space is free to use, which is the first advantage he found in 666.

Otherwise, he would rather carry these two test tubes with him, as the items in the system shop are extremely expensive.

Two test tubes cost a thousand energy points. If medical equipment in this era weren't so inadequate, Jiang Bubai wouldn't have spent those energy points.

Jiang Bubai glanced at the empty room and turned to leave.

"Kyojuro, let's go."

Jiang Bubai came to Rengoku Kyojuro's side and walked out with him.

"Wu, where's your kitten? Isn't it coming with you?"

I was a little surprised that I didn't see 666 in Rengoku Kyojuro.

"Hmm? Ignore it."

Jiang Bubai said casually, without any intention of going to find 666.

Although Rengoku Kyojuro found it a bit strange, he didn't ask any further questions.

It wasn't until he reached the main gate that he understood what Gojo Satoru meant by "don't worry about it."

666 was squatting in the middle of the gate. When it saw Jiang Bubai, it nimbly jumped onto his shoulder.

"So you've been here, Mr. Xiao Liu."

Kyojuro Rengoku calls himself "666" just like Tanjiro, which is quite interesting.

Good morning, Kyojuro.

666 nodded to Rengoku Kyojuro and quietly perched on Jiang Bubai's shoulder.

"666, their way of traveling is so down-to-earth."

Jiang Bubai silently complained in his heart that Rengoku Kyojuro's way of traveling was to run on two legs.

"Walking is the way most people in the world get around, while cars are mostly used by city dwellers."

Furthermore, the Demon Slayer Corps operates covertly, making this method of travel more suitable for them.

666 knows the general background of this world: the technology of this era is backward, and cars are not yet fully widespread.

Not everyone can teleport like Gojo Satoru and go wherever they want.

"666, what's the way you travel where you're from?"

Jiang Bubai had heard 666 say that there were also humans living in their area.

"Traveling? Where we're from, we just use teleportation anchors. Some humans also like to travel by starship."

The universe where 666 resides has advanced technology, and energy points are essential for maintaining their daily lives.

"It sounds pretty high-end, it's a pity I won't have the chance to see it."

Jiang Bubai pondered for a moment and concluded that it must be a completely new world with many things he had never seen before.

He really wanted to see the world that 666 lived in; it was a completely new universe.

"If the host can complete all the tasks, there will be a chance to go to our world."

666 believes that Jiang Bubai still has a chance to realize this idea.

At least its previous host did it, bringing back a starship from their world.

666 still thinks his former host was incredibly awesome; he didn't even have to spend energy points to buy him.

His starship was a gift from someone who was pursuing him.

"666, you're saying someone actually did it? Was it your former host?"

666 won't talk about things that are vague and unrealistic, unless someone has already done them.

Jiang Bubai recalled the former host that 666 had mentioned before, and realized that it must have been this amazing predecessor who had accomplished it.
