While Kabuto Yakushi was busy focusing one eye on the microscope, there was a creaking sound from the laboratory door.

He stayed away from the eyepiece, his nose twitched slightly for an undetectable moment, and then the corner of his mouth showed the characteristic smile of a zoologist observing the behavior of wild beasts: "Not long ago, I was wondering how long it would take for you to need to eat. But.

What I didn’t expect was that the Great Immortal Slug, one of the three horrors, also has a hobby of cooking..."

In a place like a laboratory where odors are regularly removed, the food smell brought by the butterfly ninja when he enters the door is too obvious.

Even though Kabuto Yakushi has no requirements for food, his appetite still whets his appetite when he smells this smell.

"Or is it that Miss Ninja used reverse psychic skills to meet with others? I heard from the Kirigakure ninja named Shiro before that Giyuu Uchiha seems to be very good at cooking."

"I'm sorry I didn't bring you one."

The Butterfly Ninja had the exact same smile as Kabuto Yakushi's, but there was no smile in his eyes.

Before she went to Shigu Forest today, she had never met Kabuto the pharmacist, but he seemed to know everything.

"As a prisoner, you must not forget to gather information. It seems that I will never let a simple boy like Bai come to deliver meals to you in the future."

This is not the first time that Butterfly Ninja has cooperated with a tainted scientist.

It's just that even though Miss Zhushi is a ghost, she clearly knows that she did something wrong by cannibalizing people in the past.

So before the decisive battle, although the Butterfly Ninja had a very unhappy relationship with Yushiro, his research with Tamashi was going quite smoothly.

But the young man in front of him was only Tanjiro's age, but he didn't feel any guilt in his heart for his actions of aiding the tiger.

The lord had clearly warned her before she came to this world, but every time the Butterfly Ninja saw Yakushi Kabuto's smile, she could feel a deep chill.

It's as if the difference between them is even greater than with Miss Tamashii, who is clearly a ghost.

"Please don't blame the child. It's not that he had to tell me this."

Yakushi Kabuto pushed the beam across his eyes, "It's just that after I gave him some advice on taking care of those experimental subjects, of course he couldn't just turn around and leave, so he bit the bullet and chatted with me for a while. But you can rest assured,

I didn't instill in him any of what you might call 'serpent juice'.

"But on the other hand, as you said, if such a soft-hearted person becomes a ninja, even if he has a strong blood inheritance limit, he may not last long. If you want him to live a few more years, then you must not let him go.

he is gone……"

Butterfly Ninja's brows were slightly squeezed in the middle, obviously being told something that was on his mind.

According to Taiya Yan's estimation, probably tonight, the one named Momochi Zabuza and another ninja named Terumi Mei will arrive here.

Judging from the current situation, although Shiro likes the atmosphere here very much, he still has a unique sense of dependence and debt to Zabuza, and there is probably not much hope of staying.

"It seems that we have talked about something important."

Kabuto Yakushi squinted his eyes, but his eyes were locked on the Butterfly Ninja's, "But I have a way to make him stay. Do you want to hear it?"

"Tell me about it." The butterfly ninja said casually while putting on the experimental gloves.

"It couldn't be easier."

Kabuto Yakushi made a gesture of holding hands, "As long as that Zabuza can never get here, wouldn't everything be over? For you who have Wood Release, this should be easy, right?"

"Now that we've finished talking nonsense, let's get down to business."

The Butterfly Ninja passed by Yakushi Kabuto with an expressionless expression, as if everything the former said just now was just a joke.

[As an artificial human developed by Orochimaru, she has a very firm moral code. I originally thought she would be less human.]

A strange color flashed in the pharmacist's eyes.

Although as the Butterfly Ninja said, he was just a prisoner. But Yakushi Kabuto discovered that as long as he treated his captors as part of his observation or research, he would immediately stop feeling like a prisoner.

In the past few days, apart from sleeping, he and Butterfly Ninja could be considered to get along day and night, but the more they communicated, the more he felt that Orochimaru was really a genius, and he could actually instill a set of ways of thinking and principles of behavior that were completely different from his own.

Entering the brain of the artificial human, it even made Butterfly Ninja truly believe that he once had a family...

As for other possibilities, Yakushi Kabuto never thought about it.

Knowledge is the only thing he can trust. The only explanation for the genetic matching between the Butterfly Ninja and Senju Hashirama is the artificial human!

However, even artificial humans can have the concept of "who they are" by relying on false memories, so why doesn't he?!

"Since you don't want to talk, let's get back to the research."

Kabuto Yakushi was not in a hurry to provoke the Butterfly Ninja to doubt his own existence, "During your absence in the morning, I compared your cells with Hidan's cells without permission."

Seeing the danger in Butterfly Ren's suddenly frightened gaze, Yakushi Kabuto hurriedly added: "I just think that this will make it easier for us to understand what Hidan is. The experimental results prove that you are indeed very good to a certain extent.

resemblance……"

Butterfly Ninja didn't like this description very much, but Yakushi Kabuto's description really attracted her attention: "Would you like to explain your discovery in detail?"

"It would be more convenient to show you directly."

Yasushi Kabuto walked to the computer and after a few clicks, a picture appeared on the screen.

"First of all, these are your cells. They are no different from Senju Hashirama's cells. Even if they are separated from your body, they can survive on their own and remain active for a long time. Originally, I just thought that your cells were just able to store more energy than ordinary people.

It’s just too much energy.”

Kabuto Yakushi held down the plus key on the computer and gradually enlarged the image, "But until I noticed that you didn't feel weak despite not eating for several days, I couldn't help but start to wonder about the source of the energy in your body, so I made a guess.

.”

The image was further enlarged until it began to model a lake. The Butterfly Ninja was a little confused at first, but soon discovered the anomaly in the image.

"It seems you noticed it too."

Yakushi Kabuto pointed at a kidney-shaped color block on the screen, "Your cells not only have mitochondria for energy conversion, but also things like chloroplasts used in plants to synthesize energy. When I use sunlight to

After stimulation, it will slowly move to the edge of the cell, which is also in line with the action rules of the chloroplast itself."

The Butterfly Ninja was slightly stunned. This explained why she could produce so much chakra without eating.

"So, I'm actually doing photosynthesis?"

Regarding the term vegetative state, she couldn't help but have a new concept in her mind, "Like a green leafy sea slug?"

"No, photosynthesis is just one of its functions."

Yakushi Kabuto shook his head and corrected: "The tissue in your cells that we tentatively call chloroplasts does not only respond to sunlight. In fact, when I released ninjutsu next to it, it also showed the same behavior as when it encountered sunlight.

The same activity rules. In other words, high temperature, high heat, and even strenuous activities can make it, like a plant under the sun, continuously move external energy into its cells and store it for a long time. This is why it has such abundant energy.

The reason why the body's resilience can still remain active in the dark even if it is separated from the human body...

"This ability to absorb and produce energy on a large scale, coupled with the huge energy capacity of the Senju clan's cells, is probably the real reason why Senju Hashirama is called the 'God of Ninja'."

Kabuto Yakushi paused, "However, that was before Hidan's cells were discovered."

He tapped on the keyboard and switched pictures, and the laboratory was immediately enveloped in red light from the screen.

Even under a microscope, Hidan's cells were still unclear, as if each cell was shrouded in some kind of red-black smoke, clearly rejecting outside research.

Butterfly subconsciously pursed her lips.

When she and Zhu Shi were studying the blood of the Shangxian ghost, the scene they saw was actually clearer than what was on the screen.

This shows that the purity of the "no blood" in Hidan's body is much higher than that of Shangxian Ghost.

Although she had been unwilling to admit Giyuu's worries before, it now seemed that Hidan had indeed obtained Kibutsuji Mukai's cells through so-called prayers and dreams, and there were a lot of them.

"I don't need to say more about the vitality of this kind of cells. If Senju Hashirama had only one head, he would never survive, but Hidan can. Even if we hadn't restricted his living space, his

The body can still grow back!"

Speaking of this, Kabuto Yakushi couldn't help but get excited, "If Hashirama's cells are super energy-generating machines, then each of Hidan's cells is a huge source of energy itself. We have done experiments before, and it's less than one milligram.

The energy released by Hidan's blood can instantly destroy all the cells of a six-kilogram snow rabbit from the Land of Water, leaving not even the genetic material behind. This in itself is the most important evidence. I really don't dare

Imagine if this blood entered the body of a powerful ninja with a special physique..."

【Then the whole world will end.】

The blood on Butterfly Nin's face gradually faded.

During the final battle, Muzan Kibutsuji could only destroy one district of Tokyo because all he could eat were humans.

Considering that Wuhan cells have the ability to plunder high-quality DNA (such as overcoming sunlight), once such cells spread in this world full of blood boundaries and chakra, the damage they can cause is simply unimaginable.

"Beware of sharks..."

Butterfly Ninja murmured to himself, remembering Giyuu's warning when he was unconscious, and couldn't help but feel the same worry as Giyuu.

That shark swallowed Hidan's entire torso! It's unknown what kind of monster it would have turned into if it had survived.

But if it disintegrates in the sea because it cannot withstand ghost blood, what impact will it have on the fish that accidentally eat Hidan's blood, and on the humans who feed on sea fish?

"What did you say?" Kabuto Yakushi didn't quite understand, "What does this have to do with sharks?"

"It doesn't matter." Butterfly gave him a sullen look, causing goosebumps to appear on the latter's body unconsciously. "Since you have conducted the experiment, have you found a way to weaken this kind of cell?"

"Why do you ask that?"

Kabuto Yakushi felt a little strange, "When you find such a cell, your first reaction isn't how to use it? On the contrary, you seem to be very worried about this thing..."

[Coupled with the fact that people in this world are obsessed with power, I am afraid the situation will become even more serious! 】

Butterfly Ninja did not answer, but continued to ask: "What about sunlight? Can sunlight damage this kind of cells?"
To be continued...
