"You madman..."Looking at the weak test subject in front of him, Amamiya Kenichi scratched his head, he didn't really want to torture this test subject, but there was no way, only he had cancer cells now.

If Kenichi Amamiya wants to develop the ninjutsu he envisions, then this is the only way to do it.

"Don't worry, I'm not here to scratch your eyeballs today." Kenichi Amamiya looked at the other party's bloody eyes and sighed.

The only thing he can be sure of now is that the yang attribute chakra does have the ability to stimulate the growth of cancer cells, but now this experimental base cannot achieve the effect of a sterile laboratory, so the cancer cells do not survive in the outside world for a long time.

Therefore, in order to continue the experiment, Amamiya Kenichi could only choose to directly carry out live experiments, trying to inject the yang attribute chakra into the other party's body to stimulate cancer cells.

"Let me think about it, first of all, I need to inject the yang attribute chakra into the other party's body, and then I also need to establish a recognition and identification mechanism to discover the existence of cancer cells in the fastest way..."Amamiya Kenichi thoughtfully took the pen and recorded his thoughts.

In Kenichi Amamiya's opinion, if this ninjutsu of his own wants to be developed, then the first thing to do is to let his chakra be infused into someone else's body.

There are some difficulties in this point, although he has begun to adapt to this powerful physique between the Thousand Hands Pillar during this time, he has not been able to condense the yang attribute chakra and pour it into the body of others.

And even if this step is solved, there is still a crucial difficulty, that is, how to make the positive attribute chakra act on cancer cells?

It is important to know that although there are cancer cells in the body of a normal person, they will not have developed and fixed their location like this experimental subject, and most people's cancer cells are born in various parts of the body and then destroyed.

You also have to assume that if there are no cancer cells in the other person's body, how to deal with it.

"It's too much trouble... I might as well create a cancer cell directly in the other person's body, and then make it easier for the cancer cell to grow quickly, and also control the area of damage. Kenichi Amamiya slammed his palm.

He thought too much about it before, but in fact, there was no need to be so troublesome, just create a cancer cell in the other party's body.

After all, it is not easy to find cancer cells in a large number of cells, and it is not a small task, but it is very simple to make a cancer cell.

Kenichi Amamiya was immediately interested, he didn't use the brain of this experimental subject this time, the other party's cancer cells were concentrated in the head, and he could try to create cancer cells in the other party's lungs.

As for how to make cancer cells, Kenichi Amamiya also has his own ideas, and normally the production of cancer cells is caused by damage to the DNA of normal cells, which leads to the transformation of normal cells.

Of course, it is also affected by some carcinogenic factors, such as the presence of nicotine when smoking, which may cause lung cells to turn into cancer cells.

And if the cancer cells are not recognized and destroyed by the body at this time, then lung cancer will develop.

The lungs are very important organs, people need lungs to breathe, and if there is lung cancer, the impact on the body is also very large.

"Come and smoke a cigarette?" Amamiya Ken smiled and handed over a cigarette, there is smoke in the Hokage's world, which is good news.

The subject didn't want to speak, he thought that this person was absolutely crazy, and he still smoked in such a situation?

The other party doesn't smoke, and Kenichi Amamiya doesn't care, he still knows how to extract nicotine from cigarettes.

Tobacco is incorporated into 95% alcohol, and then extracted with instruments in the laboratory, and the nicotine is already in solution, which is not very complicated.

"It's a pity that nicotine can't crystallize, otherwise it would be more convenient." Kenichi Amamiya sighed.

However, nicotine can be frozen in a liquid state, but Kenichi Amamiya doesn't need to do this, he directly fills the nicotine solution into a spray device, and then sprays it on the subject's chest.

"What are you doing?" The subject was a little frightened, he didn't know what Kenichi Amamiya was doing, and the fear of the unknown made him tremble.

"Don't get so excited." Kenichi Amamiya is very calm, nicotine can be absorbed by the body even if it is sprayed on the skin, and if it is injected directly into a vein, then it can still have the ability to kill.

However, this is a toxin, so ninjutsu such as Minor Suffering Extraction can directly extract nicotine.

"Although it can be extracted, but there must also be a medical ninja, and without a medical ninja, wouldn't you have to carry it yourself?" Amamiya Ken's eyes lit up, and this could probably also be used as a method of poisoning.

Kenichi Amamiya remembered that the nicotine in twenty-five cigarettes was enough to kill an adult, but if it was injected directly into a vein, then the amount of nicotine in four cigarettes was enough to kill.

"But it's not very easy to inject nicotine into other people's veins these days." Kenichi Amamiya shook his head, ninjas are not stupid.

But this point Amamiya Kenichi thinks can still be recorded, anyway, cigarettes are easy to get in the ninja world, and sometimes it's hard to say that they can really have some unique effects.

But then Amamiya Kenichi discovered a problem, that is, the physical fitness of ninjas in the ninja world is far more than that of previous lives, so the nicotine content of a few cigarettes is enough to kill and still needs to be experimented.

Amamiya Ken focused on the experimental subject in front of him, and how to make nicotine accurately affect the lungs still requires a lot of experimental data.

Thinking of this, Amamiya Kenichi decided to give this unlucky guy a better meal, so that the other party also has the physical strength to support him until the end of his experiment, otherwise he can't go early, and where will he go to find the test subject?

...

“... What did you do to this guy? When Orochimaru came back, he saw the dying illegitimate son of Hinata, and if it wasn't for the other party still alive, he wondered if his disciple had killed someone.

"Hehe, I did some experiments on him to find out how those special cells in his body were born." Kenichi Amamiya smiled embarrassedly.

Orochimaru left for eight days, and he also did an experiment for eight days, and at first the other party could still scold and scold people, but then he stopped talking directly, and he looked like he was being played bad.

However, there has been some progress in research during this time, at least the current Amamiya Kenichi has been able to inject the yang attribute chakra into the target's lungs.
