Naruto: The Strongest Sage

The old man was very happy.

Karin went to school happily. Yes, very happy. And this was only her second week of school.

Perhaps the scumbag of the Kusagakure was too unkind. Karin's experience in Konoha School made her have some normal life for a long time.

Karin's enrollment was not a big deal. In addition, Aoba clearly felt that the upper echelons of Konoha had relaxed their attention on him. So the enrollment was very smooth.

However, because Karin's foundation was too weak, she did not enter the same level as Sasuke and Naruto. Instead, she was one level lower than them.

This was actually what Aoba wanted. He did not want Karin to get too close to the Twelve Little Strongmen of Konoha. Those children either had family inheritance or were Jinchūriki. There are too many eyes on her.

In the future, Karin will definitely participate in various experiments of her own, and she will have many more secrets. Too much attention is not a good thing.

In Karin's world, there are not so many children from noble families. There are more civilian ninjas, so her life in school is still very happy.

And Karin is different from Naruto. Although she is not as good as Sakura, she is still very good at least.

And maybe because she knows that her current life is not easy to come by. She studies very hard and has a solid theoretical knowledge.

After checking Karin's homework, Aoba was very satisfied.

"Okay, that's it for today. The little brats outside are your friends. They have been waiting for a while. Go play, and remember to come back for dinner in the evening."

"I know, I know, you are more nagging than your mother." Karin waved and rushed out of the door. Go play with your friends.

Behind Aoba, Yumi looked at Karin's figure and her eyes moistened slightly.

"Aoba, thank you so much."

"Haha. There's no need to be so reserved. To be honest, watching a child grow up healthily and happily is a kind of enjoyment in itself."

"Your thoughts really don't seem like a ninja."

"Haha, ninja. What exactly is a ninja? Who determines this definition? I always believe that everyone has their own answer. As long as you stick to your heart, it's right."

"You are really different from other ninjas I've seen."

"Maybe, okay, let's continue. You be my assistant."

Every time after returning home from a mission, Aoba would go straight into the laboratory.

The study of sealing techniques has been going on for a while. His learning ability is still quite strong. Thanks to the strong mental power and the basic abilities he learned in his previous life. He quickly got the hang of sealing techniques.

The sealing techniques in Naruto are widely used.

The most common one is the scroll that seals materials. However, that thing is not for the user to perform the sealing technique. In fact, the sealing technique is drawn on the scroll in advance. The user only needs to inject chakra to start the closure, which is a fool-proof operation.

Moreover, this scroll is quite expensive. At the same time, it is easy to damage. After using it a few times, it will be discarded.

After understanding the basic logic of the sealing technique, Aoba did not study other advanced sealing techniques in depth. Because he needed a technique that did not exist in this world.

He wanted to seal the vitality that overflowed when Karin drew blood with the blood. Make a potion that can be used at any time.

This requires a small but very precise sealing technique. Aoba found a lot of sealing techniques for reference, and then tried to develop a suitable one himself.

This is not an easy task. It is more than twice as difficult as developing ninjutsu before. Fortunately, Aoba has enough information in his hands.

Orochimaru is worthy of being the little Doraemon of Naruto. He has a lot of good things in his hands. It is estimated that except for the sealing technique that only the Naruto knows, such as the Shiki Fuujin, he has almost all the sealing technique information recorded in Konoha.

Aoba has failed many times before. But a lot of experience has been accumulated. This technique has been basically completed. Now it is time for the final test.

On the table in front of him is a complicated technique. In the middle of the technique is a metal cylinder the size of a needle tube, which contains Karin's blood.

At this time, the vitality in the blood has been successfully sealed. But this technique is still too complicated and too large. It cannot achieve Qingye's goal.

His requirement is that the technique must be able to be concentrated into a container as big as a needle tube. At that time, whether it is injected or drunk directly, it will be more convenient. At the same time

, and it is more convenient to carry.

Qingye pressed his hands around the cylinder and injected his chakra. After a while, the spell on the table began to slowly wriggle. Like a living thing, it slowly climbed up the body of the metal cylinder.

The fine and complex spell appeared on the metal cylinder. While Qingye was operating, he carefully sensed the changes in the blood inside the cylinder.

The whole process is not complicated. But it requires a considerable amount of chakra and extremely high chakra control. Qingye soon felt sweat on his forehead. At this time, the spell was only compressed by about half.

At this time, Yumi next to him took out a soldier pill in time and stuffed it into Qingye's mouth.

The chakra supplemented by the soldier pill finally allowed Qingye to hold on and barely completed the first compression process of the sealing spell.

Yumi took a towel and wiped the sweat off her forehead. Qingye couldn't wait to pick up the metal cylinder. Carefully sensed it.

"It looks like it's successful. But we still need to test it in practice."

Aoba took a kunai and cut a wound on his arm. Then he picked up the blood next to him and drank it.

After a few seconds, the wound on his arm began to heal. But what worried Aoba was that the speed was not as fast as he had imagined.

It took about thirty seconds for the wound to heal completely.

The effect was completely acceptable. But the speed did not meet his requirements. In Aoba's memory, Karin's recovery ability should be that the penetrating wounds in the body can be healed quickly within ten seconds.

He thought about it, looked at the remaining blood, and thought of a possibility.

"It's blood. This kind of seal forcibly seals the vitality in the blood. After entering the human body, there is a release process. This process causes the effect of wound recovery to slow down."

Find the cause, and the problem will naturally be easier to solve.

So far, the development of this medicine has actually been basically successful. Even if the last problem is not solved. This thing is definitely a super high-value recovery product.

Who wouldn’t want a potion that has no side effects and can quickly heal injuries?
