Orochimaru took the initiative to contact him this time, and in addition to exchanging skills, he also left him a psychic contract scroll as a way for the two to communicate for a long time.

This means that after developing the technology of therapeutic agents, Orochimaru has already raised his position from an apprentice and assistant to a collaborator.

The day after Orochimaru left, Yayoi applied to the hospital for discharge.

The attending physician in charge of him had a little complaint about this, but Yayoi was more aware of his physical condition.

The remaining injuries can be cured in the hospital. With his vortex clan's physique, it is no problem to heal on his own.

Therefore, after the excuse of the Third Generation Naruto mission was moved out, the hospital could only release people.

...

When he came back from the hospital, Yayoi first returned to the small courtyard where he raised rabbits.

After not seeing each other for two weeks, these rabbits are pretty good.

At this time, the rabbit's estrus period was over that month, and half of the rabbits had entered a pregnancy state, and some new rabbits had even been born.

During Yayoi's mission, Kushina was taking care of these rabbits on his behalf.

This week after returning to the village, Li Yi also helped in the rabbit house.

Compared to Yayoi's period of breeding, these bastards not only did not lose weight, but instead became round and round, with their entire fur shiny.

"It should have been slaughtered a few days ago. These rabbits are a little over-age..."

Looking at these fat and round white-haired beasts, Yayoi touched his chin:

"Otherwise, call Li Yi and the others over and hold a full rabbit feast?"

In the end, the whole rabbit feast did not start.

Most of the ninjas during this period were very busy. Since a large number of Zhongnin were on the front line, many C-level and D-level tasks were piled up in the village.

Even the newly graduated Shinin is busy every day and has to leave the village from time to time.

Only Kushina, because she is the next Jiu-Tail Tsukiri, basically doesn't need to perform tasks.

Since Yayoi was discharged from the hospital, she would come over for free every day without any movement.

Seeing her like she was doing nothing, Yayoi felt aroused and had a bold idea.

‘Do you want to train Kushina to be my experimental assistant?’

After having this idea, Yayoi began to teach Kushina to learn various potions, introduce various types of beakers, beakers, test tubes, etc., and understand the usage of various experimental instruments.

However, after wasting two full days, he had to admit that Kushina had no talent to become a research assistant at all.

Her talent in this area is worse than her cooking skills!

This woman is a big confused person.

When cooking, she would make mistakes in salt and sugar, mix soy sauce and vinegar.

During the experiment, she couldn't tell the acid and alkaline properties of the reagents. She didn't use a pipette when pipetting, and did not turn off the constant temperature box when culturing cells.

No matter how many times she reminds her, she will do whatever she wants.

In this regard, her memory is like a fish, only seven seconds.

In the lab, Kushina causes much more damage than she does.

Yayoi had no choice but to give up the idea of ​​raising her into an experimental assistant and only handed over the work of feeding rabbits to her.

These rabbits are all resistant to rough feeding and are highly adaptable to the environment. In short, they are resistant to fucking, which is suitable for clumsy women like Kushina.

...

After restarting the experiment, the first thing to do is to improve the current therapeutic agents, which is one of the agreements made with the three generations in advance.

With the help of Konoha ninjutsu information and medical experimental reports that were to come from the Third Generation, Yayoi began to read the experimental records of the Medical Department one by one to find inspiration for improving the drug.

Soon, from a recent experimental report, Yayoi found what he wanted.

In fact, this experimental report is the experimental record of Konoha Medical Department analyzing Yayoi therapeutic agents, which is the cracking record of the drug formula.

The third generation did not even hide such things. On the one hand, it was open and honest to express the sincerity of the senior management.

On the other hand, he was also trying to beat Yayoi and showed him the technical strength of the medical department.

Even Yayoi has to admit that Konoha is indeed full of talents.

Without Tsunade, he could actually crack the method of using interferon to hide the ingredients of the drug in such a short time.

What's even more disgusting is that this experimental report even puts forward an improved idea.

That is, by changing the base drug formula, the shelf life of the agent is greatly extended.

In other words, if they are not restricted by the main materials, they can not only copy the counterfeit potion themselves, but also make the potion better and have a longer shelf life!

‘Are you penguins?’

Yayoi secretly complained.

This kind of quick copying of others' achievements and even further launching enhanced products, using piracy to fight back and kill the original version is really a sense of déjà vu.

‘Fortunately the main material is my serum.’

However, thanks to the Medical Department's "Penguin Act", Yayoi also happily made a "copy ninja".

He directly took out the improvement plan of the medical department, adjusted it a little, and then used it directly.

It can only be said that the "penguin" will eventually be "penguin".

The effects of new drugs are basically the same as those of old drugs, but the shelf life has changed from one to two weeks to up to three months, and the requirements for the drug storage environment have been greatly reduced.

So Yayoi did not give it a new name, but simply added the word "change" at the end, which is "type 1·fast-acting treatment agent·change".

He had just made improvements, but three generations there began to urge him to ask for goods.

However, it is known that the main material of the agent is Yayoi's serum.

Considering that he was just discharged from the hospital and was weak, the urging there was not a hurry, and the number required was relatively small, only one hundred.

Here you can also see the difference in the previous pattern between the Great Ninja Village and the Small Ninja Village.

If it were in the Konishi Village, Yayoi would probably be forced to draw blood for medicine regardless of his life, just like the treatment of Kasumi mother and daughter in anime.

However, the Okinawa Village will not be like this, especially when the war against the Wind Kingdom is very good.

Of course, if it were someone like Danzo, it might be another way of saying that he was too good at sacrificing others to achieve himself.

Uchiha is so powerful that he can destroy his own combat power.

However, in seven or eight years, by the third battle, my situation may be a bit dangerous.

By then, Konoha, who was almost beaten to the door of her house, would not consider whether she could fish in the dry pond!

From the time of exposing the special abilities of one's own serum, there are only two ways before Yayoi:

The first path is to clonize the hematopoietic organs and produce their own blood outside the body.

The second way is to make yourself stronger during the seven or eight years of vacant period, so strong that no one dares to do anything to himself.
