Yakushi Ye Naiyu's learning talent is quite good, and in more than a year, he has learned all the medical knowledge from Jiekang Miki, and has learned two medical ninjutsu; In addition to his lack of experience, Yakushi Nonoyu has learned all the skills of Kaikang Miki.

If you want to improve in the future, you can only go to Konoha Hospital to learn, and there are only two medical ninjutsu of the Jiekang Miki Society.

Karn was already very satisfied with Nonoyu's situation, and he was going to recommend Nonoyu to Tsunade to study for a while; Although she has already been divided, with Tsunade's status in Konoha Village, it is still very easy to ask for a shinobi.

In this way, she can also avoid Tuanzang, at least Tuanzang will not blatantly snatch people from Tsunade's side, otherwise with her fiery temper, she will definitely not give up.

Just as Karn was thinking about it, Tsunade went straight to the door to find him, but when Karn saw Tsunade, he felt that she was in a bad mood, not like she was lost, but simply angry.

"Are you running into a dog on the road?"

Karn asked jokingly as he poured Tsunade a cup of iced lemon tea for her to extinguish the fire.

Upon hearing Karn's words, Tsunade burst out laughing, thinking back to what had just happened, no different from running into a dog; Although it's not good to think so, the old man's approach to the three of them is really disgusting.

"I'd like to discuss with you about cooperation..."

When it came to business, Tsunade was a little squirming, she didn't know how to speak; I just went home and checked the treasures of the Thousand Hands Clan, and found that there was really not much money or anything, and the most precious thing about the Thousand Hands Clan at the moment should be those houses and the research notes left by her second grandfather.

The rest of the bits and pieces should add up to more than 100 million, which seems to be a lot, but it costs a lot to buy instruments.

Karn saw that Tsunade didn't speak for a long time, and couldn't help but ask, "Tsunade, it's rare to see you so cowardly, could it be that you agreed to cooperate, but couldn't come up with anything?" ”

"How is it possible, it's just those people in the village..."

Tsunade hurriedly shook his head, and then no longer concealed it, and briefly said the attitude of Sarutobi and the others, although there was a lot of embellishment in it, Karn still heard the word greed from it.

"You still have those things at home, I'll take care of the research equipment and experimental human body, I'll go to other places in the Fire Country to buy some death row prisoners, it shouldn't cost much..."

Karn calculated in his heart that the lives of the ninja world were much cheaper than those of the United States, and if there were too many condemned prisoners in the Fire Nation Prison, one person would be able to get 100,000 taels, or even 50,000 taels; As for the instruments, he brought some more advanced instruments from there, and the results would be used for himself anyway.

"It's better not to think about the serum, the serum of a desperate virus is so precious that you can't imagine, if it comes out, you will be given at most one; You must know that the cost of a serum is almost 100 million taels, and if your village doesn't pay for it, you still want to..."

"If it weren't for you, I might have tried my luck elsewhere."

When Tsunade heard this, he hurriedly said, "I know, I'll tell them about this when the time comes." "If Karn was really scared away, then there was no hope of Rope Tree becoming a ninja.

After reaching a consensus, Tsunade and Karn discussed a joint experiment.

It's best to keep the laboratory outside the village, but don't be too far away from the village, when doing human experiments, the living people go in and the corpses come out, so that the villagers can see that it's not good, and Tsunade is also busy with the affairs of the Konoha Hospital, and it's too far away to take care of it.

After the location was confirmed, the experimental base was built by Tsunade in charge of finding the ninjas, and Karn was in charge of the instruments and equipment, as well as going to buy death row prisoners from all over the Fire Country; On Tsunade's side, when everything is ready, he will begin experimenting with the fusion of the Desperation Virus and the cells between the columns.

The amount of serum is limited, and only two can be given to Tsunade at a time, giving Konoha a phenomenon that serum is expensive; Fortunately, Karn had all the information about the Desperate Virus, and he could make it without telling Maya, otherwise it would not be possible to take it from the laboratory every time.

After finalizing a few things, Tsunade went back to prepare

Tsunade thought as he walked home, the intercolumnar cells were easy to say, and he remembered that the second grandfather sealed a batch after the failure of his research; As for the Earth Escape Ninja, it's good to find Orochimaru, there are few people in the village who are stronger than him, and it is impossible for Orochimaru to refuse her.

Inside the Hokage building.

"Hizai, are you sure there won't be a problem with this method?"

Zhuan Koharu asked with some concern, you must know that although Mito-sama is still alive, his physical condition is already very poor, and if something happens to Jiu Sinai, they will not have the next Nine-Tails Human Pillar.

"Don't worry, I've arranged a lot of shadows, and the border to the Land of Thunder has also been tightly sealed, so they can't get out."

Sarutobi spat out a puff of dry smoke and said very decisively: "This is a good opportunity to cultivate the bond between Kushina and Konoha, after this incident, she will be grateful to Konoha; And Yun Shinobi's spies can also help us test Karn, if we can get the secret of the medicine from him..."

This is Tuan Zang's suggestion, and he also thinks that he can, if Konoha is not convenient to do it, he can just take advantage of Yun Shinobi's idiots; As long as Konoha has no traces of meddling, even if one Karn dies, the forces behind him will send people over again, and they will not be jealous of Konoha head.

Sarutobi thinks that this can be carried out, not only to remove Yunshinobi's spy in the village, but also to make Kushina feel good about the person who rescued her, and finally to test the secret of Karn.... Give it a try!

...............

After finalizing the cooperation, Karn decided to arrange things in Konoha Village, and went to prepare the research equipment for death row prisoners and the Desperate Virus.

In the afternoon, Kushina suddenly came to the door, it was her first day on the mission team, and Karn had thought she wouldn't come.

However, since he came, Karn still entertained Kushina, poured her a cup of tea, and asked, "How was your first day as a ninja?" ”

"It's not interesting, after introducing yourself, it's a real combat exercise, and there is a problem with the leader of the team, I hope we don't say it early as soon as we work together, and we have to wait for us to cooperate before announcing it..."

"This shows that your leader Shinobi wants to train you, so..."

Before Karn could finish speaking, he suddenly heard a shout from the front, "Is the boss there?" I want to buy something. ”

"Someone wants to buy something? Boss, I'm going to help you..."

Jiu Sinai hadn't experienced sales yet, and when she came just now, she saw that the clerks were off work, so she wanted to try to be a clerk; Before she could get out, however, Karn was dragged back by the collar behind her back.

"Come back for me, stay here, I'll go and have a look."

Karn said to Kushina in a slightly solemn tone, the wooden door has been closed just now, if it is a guest, at least knock on the door and come in, what are you going to do when you open the door and shout directly?

And this is a dessert shop and not a pharmacy, so I see that the dessert shop is closed, so I am in such a hurry to eat dessert tonight?
