"This ninja's physical fitness is good, and it seems that he also has a certain resistance to the yang attribute chakra." Kenichi Amamiya observed the undulating chest in front of him with interest.

In order to make himself look more carefully, he even dismantled his ribs, although the other party will definitely not live long if he does this, but it doesn't matter if Kenichi Amamiya does.

He had just succeeded in triggering cancer in the ninja's lungs, and something strange had begun to appear in the other person's body, which was a pre-cancer manifestation.

"Ahem, ahem..."The subject began to cough, and Amamiya Kenichi silently increased the amount of injection, and he was trying to accurately inject the yang attribute chakra into the cancer cells that already had a certain scale.

What are cancer cells? It is a malignant cell that will rob other cells of nutrients to accelerate their own division and growth, and at this moment these cancer cells have more abundant life energy.

Almost visibly, the cancer cells spread much faster, and the subject began to cough up blood and have difficulty breathing.

"My idea is right, the positive chakra can stimulate the growth of cancer cells, thus artificially creating cancer in the target body." Kenichi Amamiya was a little happy, and now there are preliminary results.

As long as you can summarize this set in the future, and then test the probability of success, then Kenichi Amamiya can say that he has successfully created a unique ninjutsu.

"But I remember that there is a medical ninjutsu called the technique of extracting toxins, which can extract toxins or something, but that thing should be useless for my ninjutsu." Kenichi Amamiya touched his chin.

At this moment, Kenichi Amamiya can already accurately inject the yang attribute chakra into these cancer cells, and he found that the other party's cancer cells have begun to show signs of metastasis.

If there is a large-scale transfer, in the previous life, it is basically a situation where you can book a crematorium and wait for death.

Amamiya Ken stitched his body together, and then handed it over to the medical team in the base to find a way to treat this unlucky guy.

Kenichi Amamiya wants to see if the ninja world can deal with cancer, if it can be dealt with, then the usefulness of this set of ninjutsu has dropped a lot, if it can't be dealt with, then Kenichi Amamiya has mastered a ninjutsu that can be classified as a forbidden art.

"You're done?" When Kenichi Amamiya found his teacher, he saw two dead ninjas lying on Orochimaru's experimental table.

However, there is still some strange smell in the laboratory at the moment, and there is still some dust on the test bench.

Reincarnation of the Dirt?

Amamiya Ken instantly thought of this unique forbidden art.

"Yes, teacher, the experiment has some results, and now I have handed over the test subject to the medical team and asked them to see if they can treat each other well." Kenichi Amamiya pretended not to understand at all and said very respectfully.

"Well, don't forget to practice ninjutsu, that's what we ninjas rely on to make a living." Orochimaru nodded, he has always been very decentralized.

In other words, there is no need to be suspicious, and there is no suspicion in employing people, in general, he is a very good leader, of course, indifference and ruthlessness are also one of his characteristics.

"Good teacher." Amamiya Ken nodded, he had made a plan for himself during this time.

The first is the training of ninjutsu and physical fitness, which can't be put down, and then the task assigned by the teacher, and the last is to research and improve the ninjutsu of cancer manufacturing.

After obtaining the immortal body between the Thousand Hands Pillar, Amamiya Kenichi had an extra Yang attribute chakra in his body, and the only pity was that Amamiya Kenichi did not master Mu Dun.

This made him a little disappointed, after all, Mu Dun is still very strong in the ninja world, and with Mu Dun, then he can catch and study the tailed beast.

Thinking of those tailed beasts with different abilities but very strong strength, Kenichi Amamiya drooled a little, although the tailed beasts in the later stage looked like they didn't have any face, but in essence, their strength was also very good.

Otherwise, it would not have become a force that is highly valued by each ninja village, and its status is comparable to that of a nuclear weapon.

"I have a ninjutsu I'm going to teach you." Orochimaru still sat peacefully in his chair, but when he spoke, Kenichi Amamiya felt his heart beat pause.

After all, this scene really can't make Amamiya Kenichi think about it too much, the reincarnation of the filthy earth is a very powerful forbidden technique, although it requires the summoner's body tissue, but the ninja world does not have the habit of cremation.

I don't know how many cells there are here, and I don't know where the grave of the second generation is Kenichi Amamiya.

"Is the teacher the Thunder Escape Ninjutsu of Yunyin Village?" Kenichi Amamiya asked excitedly, he couldn't be too special, and according to his strength, it was theoretically impossible to come into contact with Konoha's forbidden technique.

"No, it's another powerful but dangerous forbidden art." Orochimaru casually threw a scroll to Kenichi Amamiya.

Amamiya Ken opened it and glanced at it, and the words "Filthy Earth Reincarnation" were printed on it.

Although he knew that it was very likely to be such a ninjutsu, but when he really saw it, Kenichi Amamiya had to admit that his heart was beating fast, after all, this gate control technique was indeed very powerful.

"How do you feel after reading it?" Orochimaru took a sip of tea, then glanced at Kenichi Amamiya, he wanted to see what the disciple he had chosen had in mind about this forbidden technique.

"It's very powerful, but there are also some dangerous ninjutsu, and it's very practical, but once you use it, it's also very troublesome." Kenichi Amamiya has already finished reading it, after all, it's not very long.

"Why do you say that?" Orochimaru was noncommittal.

"Because it can resurrect the dead, this is a ninjutsu that blasphemes the dead, and once it is used, it is destined to cause disgust among many people." Amamiya Kenichi is a little helpless, his own teacher just likes to ask knowingly.

He didn't believe that these discerning people could see the truth, and his teacher couldn't see it, he was Orochimaru.

"But it's also very powerful, if you can let those dead have a certain amount of strength, it's a very good combat power, and you don't need to worry about other problems." Kenichi Amamiya shrugged.

The ninjutsu of filthy earth reincarnation is indeed very powerful, not to mention anything else, on the night of the Nine-Tails Rebellion, if the filthy earth was reincarnated as the first and second generations, how would the Nine-Tails deal with it?

"Then I teach you, do you dare to learn?" Orochimaru smiled, then asked.

"Of course you dare!" Amamiya Ken nodded immediately, this is a forbidden technique, and it would be a fool not to learn it.
