Demon Slayer: Become the villain Boss Muzan

Chapter 166

The cleaning lady glared at Tanjiro and closed the door as soon as she entered.

Why does this kid always compete with her for work!

Watching the cleaning lady leave, Lei put down a stack of documents, drank a sip of coffee, and looked at Tanjiro who was busy cleaning the glass:

"What are you carrying? I don't think you've ever taken it off."

Tanjiro looked back at him and said bluntly:

"This is my sister."

Because of the special situation that Muzan left for Nezuko, other ghosts can't feel Nezuko, and Nezuko can't feel other ghosts.

So Lei really didn't know that Tanjiro was carrying a ghost sister.

Frowning at Tanjiro:

"Your sister is not like that stone pet, a doll or something like that?"

Tanjiro said hurriedly:

"No, my sister..."

As Tanjiro said this, he felt the box behind him shaking.

Nezuko has been sleeping these days, is she awake now?

At this time, Nezuko has gradually recovered some of her memories, and the lock of the box can be opened easily.

Tanjiro hurriedly stopped his work and hurriedly put the box on the ground.

But Nezuko had already opened the door and climbed out.

But as soon as she climbed out, Nezuko was still dazed and didn't react. She fell out of the box and landed head first...

Tears welled up in Nezuko's eyes. She climbed up and looked at Tanjiro with a red forehead:

Tanjiro wiped the water off his hands quickly, smiled gently and touched Nezuko's head:

"Okay, don't cry, Nezuko."

Rui watched Nezuko's forehead recover visibly, but couldn't sense the breath of a ghost or half-ghost on her body, and looked at her curiously.

Walked over, reached out and touched Nezuko's head under Tanjiro's gaze, showing a gentle smile:

"Brother, here is candy, don't cry."

Nezuko looked up at Lei, watching Lei take a candy from somewhere and put it in her hand.

Lei looked at Tanjiro again:

"Aren't you tired of carrying your sister on your back every day? Besides, your sister...isn't she a human?"

Hearing this, Tanjiro subconsciously protected his sister behind him. Although they suspected Lei was a ghost, it was not certain. What if she was an ordinary person:

"She has never eaten anyone! I will make sure she won't hurt anyone in the future!"

Listening to Tanjiro's words, Nezuko rubbed Tanjiro's clothes on his side, with a comfortable smile on her face.

Lei nodded and sat back:

"Okay, you are my employee and I believe you, but you have to be responsible for your words."

Tanjiro nodded firmly:

"Don't worry! Nezuko will never hurt anyone!"

While Lei nodded to deal with it, he contacted Muzan in his heart:

"Boss, what are you doing? Why can't I feel a ghost?"

"Nezuko?"

"Yes."

"I won't tell you!"

Lei: "..."

Forget it, just know that she is a ghost.

Moreover, he looked at the brother and sister very kindly, as if he saw the affection between his parents and him.

It also reminded him of the time when he was a child with Ling Yuzi.

But Ling Yuzi had grown up and went to play by himself.

On the other side.

Liu Shi Pharmaceutical.

Tamayo's research has made progress again. Although he still has no way to treat Ubuyashiki's disease, he has studied important things from Muzan-sama's blood.

It is naturally impossible to turn a demon into a human through drugs. After all, demons are basically flawless and there is no way to treat them.

But there is a way.

It is to start from Muzan.

The person who tied the bell must untie it.

Because turning into a demon depends on Muzan's blood, as long as Muzan can continue to improve his ability to control blood, sooner or later he will be able to control his blood to leave the demon's body, so that the demon can turn back into a human.

Tamayo understood.

At present, Muzan's blood, Ubuyashiki's disease, breathing method and the like cannot be scientifically explained at the current level of technology.

In other words, it can be understood that those things are actually related to the so-called "theology".

Muzan is the biggest unscientific thing, and his blood is his extension.

Except for those related to Muzan, almost everything else can be explained by science.

Muzan is the last unscientific thing in the world.

So if you want to do what Muzan said

The card bug operation still depends on him, not her.

After all, she is at most a techie, and can't be compared with the boss.

Tamayo sat on a chair, holding a board in her hand, resting it on the chair handle, watching Muzan explain her discovery.

Muzan was a little disappointed:

"You are not good at selling cheats."

Tamayo: "..."

To be honest, Muzan is constantly improving himself.

Those who are making trouble everywhere are basically his clones.

The ability to control blood has indeed been improving, but it will take some time to reach the level that Tamayo said.

"Okay, then you put this aside for now."

Muzan waved his hand and smiled:

"Can you help me change the color of my hair by eating cherry cakes?"

Tamayo: "?"

Lord Muzan, are your five brains useless at the same time?

We hundreds of ghosts have spent so much effort to get doctors' doctors and professors' professors, but in the end all the knowledge ran into your brain. Why can you come up with such an outrageous idea?

Listening to Tamayo's thoughts, Muzan silently took out his phone:

"Look for yourself."

Tamayo squinted suspiciously and examined Muzan before looking at the phone screen.

Then, she saw a little girl holding a sakura cake in her hand and her hair gradually changing color.

Tamayo: "???"

"You didn't photoshop it?"

"I'm so bored that I did something so outrageous to fool you? Am I such a person?"

Tamayo: (눈_눈)

"Forget it, I'll believe you for once."

If it weren't for the unedited video, Tamayo would have thought that Muzan's brain had really gone wrong because he had lived too long.

But it must be said that this outrageous thing aroused her interest, so Tamayo dismissed Muzan and excitedly threw herself into the new project.

She is the pioneer in discovering the truth!

And this little girl seems to be a member of the Demon Slayer Corps. If I tell her directly in a few days, she probably won't refuse to provide some blood and hair.

After all, the atmosphere in the Demon Slayer Corps is quite simple...?

It is worth mentioning that Yushiro has lived for so long and learned a lot. He began to help Tamayo make some equipment.

He even made great contributions in medical equipment.

He also picked up Chachamaru early, and he circled around his legs like a mascot every day.

When Muzan saw this little guy, he wanted to squat down and touch Chachamaru.

This little guy's IQ should be that of a seven or eight-year-old child.

He ran towards Muzan very actively, rubbed Muzan's palm, and meowed a few times.

Muzan smiled, picked it up and stroked it a few times.

On the other side, in the rental house.

The dead mosquito array was still there.

Zenitsu and Inosuke began to get excited, comparing who had the most fans to prove that "I am better than you."
