Betrayal Has a Terrible Start

Kaguya Otsutsuki's bloodline is basically concentrated in Konoha.

Without mentioning this, Ye Ji began to formally study the confidential information obtained from Sha Yin.

The first is drug research.

Sand Ninja is the village that is best at using poison among the five major Ninja villages, and it can be said to be an expert in this regard.

In addition to Konoha, there is Tsunade, a medical holy hand, who can also solve troubles, and the rest of the villages can be regarded as jealous of Sand Ninja's poison.

The establishment of the medical ninja was at the beginning of the establishment of the ninja village, but it received large-scale attention, and it was the experimental theory proposed by Konohakami Tsunade during the Second Ninja World War.

But in the final analysis, it is still an experimental theory, and whether it can be fully applied to war still requires various attempts.

This proposal was initially rejected by the three generations of Hokage Sarutobi.

Yes, this proposal is very good, the three generations of Hokage were once excited, but...

No money.

Training doctors not only requires a lot of manpower and energy, but also various research funds.

Tsunade is human after all, not god.

In the soil-eating era of the Second Ninja World War, although it was not as cruel as the Warring States era, even four or five-year-old children had to go to the battlefield.

However, Ye Ji remembered that she had just graduated from the ninja school, when she was only seven years old, and was thrown into the battlefield by the village to kill the enemy.

The same is true for the rest of the Ninja Village.

The cruelty of the battlefield is evident.

Young ninjas represent the future and mainstay of the village.

But the various Ninja villages are already so urgent that they have to use children to fight in an embarrassing situation.

Even the youngest child is a ninja who can kill and be killed.

There are too many dead people, most of them did not die on the battlefield, but after being seriously injured, they could not get effective treatment, or the treatment efficiency was too low, resulting in the sacrifice of many people.

The expansion of Medical Ninja was born under those circumstances.

Tsunade's proposal was good, but unrealistic.

After the Second Ninja World War, the major Ninja villages recuperated, and then gradually considered the importance of medical ninjas.

Because female ninjas are mostly weaker than male ninjas, but under the control of Chakra, they are generally superior to male ninjas.

Therefore, the quick form of medical ninja is to let every female ninja learn the necessary medical knowledge and master basic medical ninjutsu.

It's just that there are too many rigid requirements for medical ninjutsu, and the ability to control chakra is even more demanding. It is impossible for all female ninjas to meet the requirements.

Ye Ji just happened to meet this requirement, learning basic medical ninjutsu and simple medicine configuration.

Compared with Konoha's medical level, Sha Ninja's medical level is weaker, but in the research of poison, Sha Ninja is better.

Sand Ren is good at puppet mechanisms, and it is common practice to apply poison on hidden weapons.

Among the countless drug-making experts in Sand Ninja, Chiyo is the best among them.

Many of the materials Ye Ji was holding in her hands were made of poison from her handwriting.

Not only poison research, but also experience and experience in medical ninjutsu.

However, some parts were incomplete, Ye Ji didn't care, these things were enough for her to digest for a while.

Not to mention the complicated process of making the poison, after the poison is formed, an experimental body is still needed.

Although the guinea pig is good, there is no human body that is more practical.

After all, her poison is for killing people, not for killing mice.

The lights were dim, and there were three experimental benches in the laboratory, one for the elderly, one for the young, and one for the child.

Three people were injected with the same poison.

People of three ages have different physiques, which allows Ye Ji to record the reactions after poisoning more intuitively.

Watching the three people twitching on the experimental bench for a long time, their faces twisted and twitched, their pupils dilated, and their blue veins had popped out. It can be seen intuitively that if their mouths weren't sealed, that kind of painful scream must be very loud. Be harsh.

He struggled to get up, his hands, feet and head were bound on the test bench. The wrists, ankles, and neck had been frayed by the locks, and he still wanted to struggle to get up and escape from the cold test bench.

In the end, it's just a dying struggle.

"It's dead."

The old man died first.

The older you get, the less antibodies you have in your body.

This is also impossible, human beings are so fragile.

At this time, Ye Ji had a little understanding of Orochimaru's pursuit of longevity and undead ninjutsu.

In the face of birth, old age, sickness and death, everyone chose to compromise and accept, but Orochimaru chose to fight.

Ten minutes later, the child also died, with dilated pupils, because the blood of the whole body was full of poison, and the skin was black, which was quite gloomy.

There was no fluctuation in Ye Ji's eyes, just like looking at the dust in the air.

This is the ninja game, and every player is a sinful person who bears the blood of deep hatred.

Days passed like this.

The twentieth day of coming to the Rainbow Country.

What Ye Ji studied today was not a poison, but a forbidden technique.

There were a bunch of scrolls lying around in the bedroom, randomly thrown on the ground.

Ye Ji was spreading out a scroll, with an oil lamp beside it, illuminating the text on the scroll, and staring at the content recorded on the scroll without blinking, her eyes showed excitement and excitement.

Forbidden Art Reincarnation!

A forbidden technique created by the elder Chiyo of Sandyin.

But what is recorded above is not the reincarnation of the finished product, but some information and some inferences from Chiyo when he created this forbidden technique.

It is conceivable that this ninjutsu has not been created by Chiyo, it is only a semi-finished product.
