Xia Yan, who didn't have a good way for a while, had to put this matter on hold for the time being.

After that, Mito also changed the topic to a lighter one, and began to do his duty as a teacher to review the battle they had just played.

「…… Anyway, Xia Yan, that technique you just used was really interesting."

Speaking of the large rock snake that Natsuhiko made at the end, Mito had an approving smile on his face.

"I actually thought of combining the Flower Clone's Technique with Iwain's Fist Rock Technique to make up for the shortcomings of the Arm Shadow Clone's too fragile body, and at the same time, it can greatly enhance the destructive power."

"And in addition to Earth Escape, other Escape Techniques should also be able to be used in conjunction with the Flower Clone Technique to achieve different effects."

"It can be said that this is a ninjutsu with infinite possibilities!"

Xia Yan heard Mito's praise, but there was not much joy on his face, but he smiled helplessly:

"It's not like you've been easily broken by your chains, teacher."

Mito laughed, "There's no way around it."

"Natsuhiko, you may not know that in a battle above the level of upper ninja, the amount of chakra is often the key to winning or losing."

"Although that technique of yours looks quite scary, the amount of chakra contained in it is ordinary, and in terms of strength, it naturally cannot defeat my chain that has condensed a large number of chakra."

Mito said with some emotion, "It's really unfair to say, after all, the amount of chakra is actually predestined when a person is born."

"Xia Yan, although you have increased the capacity of the meridians through the cultivation method of the Foundation Building Plan, you still can't increase the upper limit of the chakra amount."

"And Natsuhiko, the rock snake you just used and my chain are both ninjutsu that will change their power according to the amount of chakra injected, so of course your rock snake is no match for my chain."

After the foreshadowing, Mito got into the real topic of today.

And this is also the reason why she took the initiative to compete with Xia Yan, and finally deliberately defeated Xia Yan with all her strength.

She smiled and said:

"Fortunately, you are my disciple, so this shortcoming is not without a way to make up for it......

Although Mito deliberately paused to create suspense, Natsuhiko had already roughly guessed what Mito wanted to say.

Sure enough, then Mito said mysteriously:

"Xia Yan, have you heard of the Yin Seal?"

Xia Yan, who has seen the original work, naturally knows very well what the Yin Seal is.

Even he knew that Tsunade would use this technique as a basis in the future to develop an S-level medical ninjutsu, the Hundred Heroes Technique.

However, he couldn't explain the source of the information, so he naturally didn't say anything, just quietly listened to Mito's next introduction.

Like Xia Yan's memory, the Yin Seal is simply to seal the surplus chakra on the forehead, and finally form a diamond-shaped mark.

Then, when needed, you can unlock the seal by casting "Yin Seal Solution" to temporarily obtain a large amount of chakra.

After Mito introduced the Yin Seal, he smiled slightly:

"So as long as Xia Yan and you master the Yin Seal, then you don't have to worry about the lack of chakra at a critical time."

"Although this technique is very difficult to learn, and you also need to master a lot of knowledge of medical ninjutsu, I believe that Xia Yan will be able to learn it sooner or later."

….

Xia Yan also nodded slowly:

"Sounds like it's a perfect fit for me."

After all, if you use the things of Xia Yan's previous life to understand, this Yin Seal is actually a power bank.

And it is also an inferior power bank that has been charged for several months and used for five minutes.

However, for Xia Yan, who does not fight frequently, this is a very cost-effective ninjutsu, which is enough to make up for Xia Yan's shortcomings of not having a lot of chakra.

So before he became a disciple of Mito, he had actually put the Yin Seal in his future

in the research program.

The difference is only that you need to do it completely in-house, but you can learn directly from Mito.

However, Xia Yan actually felt that it was not time to learn this technique yet.

Because the Yin Seal needs to constantly inject surplus chakras into his forehead to form a mark, and Xia Yan uses chakras cleanly every day of cultivation and research, where is there any surplus chakra?

Therefore, he originally wanted to wait until he had researched the chakra transformation technique before he could transform other people's chakras into the Yin Seal in one step, skipping the stage of slow accumulation.

"It seems that the technology of chakra transformation has to be put on the research process as well."

Xia Yan felt a little helpless in his heart, there were too many research projects, even if he added three small ones, his time would not be enough at all.

"I don't know if Orochimaru has researched ninjutsu that can absorb chakra, maybe this part of the content can be outsourced to Orochimaru......

After Xia Yan groaned slightly, he still decided that he couldn't let go of this opportunity to learn the Yin Seal.

After all, this technique still needs to learn a lot of medical ninjutsu knowledge, and it can't be achieved overnight, so he estimates that it will be a long time before he officially enters the stage of storing chakra, and he doesn't need to worry about chakra for the time being.

After making a decision in his heart, Natsuhiko looked at Mito and said:

"Teacher, please teach me the Yin Seal."

"Of course."

Mito nodded slightly, and said with a little emotion, "After all, this is probably the only thing that I, the teacher, can teach you."

After saying that, she added, "It's just that most of my time now is spent compiling new sealing textbooks, so most of the content of Yin Sealing still needs to be taught by yourself."

"Of course."

Xia Yan nodded in understanding.

With his current level of sealing skills, he no longer needs a teacher to teach him by hand.

Then, as if he suddenly remembered something, Mito put his hands together and said:

"It just so happens that Jiu Sinai has also recently started cultivating the Yin Seal again, so Xia Yan, you can help me guide her cultivation by the way, which can be regarded as a little bit of responsibility as a senior brother."

"Why is Kushina also learning Yin Seal?"

Xia Yan said with a slight surprise.

After all, in the original work, Kushina did not master the Yin Seal.

Mito's expression stiffened slightly, and he felt that he couldn't explain the reason why Kushina was learning the Yin Seal.

But Xia Yan didn't care too much.

Because his arrival has changed a lot of things, and it is also a good thing that Kushina is willing to learn the Yin Seal.

So he promised to tutor Kushina to learn the Yin Seal.

….

At the same time, the fact that Mito may die soon also gave Natsuhiko a lot of urgency.

So he began to think that in addition to the Yin Seal, that technique could also be taught to Kushina by the way.

And after Mito received Natsuhiko's clear answer, he also showed a satisfied smile, and said silently in his heart:

"Kushina, I can only help you get here......

……

The next morning.

Kusina went out early in the morning and walked happily towards the street in the southeast corner of Konoha.

Today she was dressed up extraordinarily beautifully, and even wore a red cheongsam that she was usually reluctant to wear.

This is because she received a message from Xia Yan through the bracelet last night, asking her to go to his house tomorrow morning, saying that she has something very important to say to her.

"I don't know what the important thing is, is it ......?"

Kushina put her hands behind her back, and two blushes appeared on her face from time to time, obviously thinking of something strange.

Soon, Kusina came to the door of Yusheng's house.

Speaking of which, it was the first time she visited Xia Yan's house, and she was a little nervous.

She glanced at the bracelet, thought about it, gave up the way of using the bracelet to notify Xia Yan, and chose to knock on the door directly.

It's more ceremonial.

Winter, winter, winter.

After a few knocks on the door, Kusina heard a light footstep coming from inside.

She became more nervous, and couldn't help but check her outfit again, and then returned to her nonchalant appearance the moment the door opened.

However, her casual expression quickly broke down, because she was surprised to see that it was not Natsuhiko who opened the door, but a little boy with white curly hair and blue clothes.

After a closer look, Kusina also found that this child looked very similar to Natsuhiko.

Could it be the child of Xia Yan's relatives?

This thought naturally came to Kushina's mind.

So she smiled, leaned over slightly, and asked in a gentle tone:

"Hello, is Natsuhiko at home?"

The little boy's eyes rolled and said in Conan's cute tone:

"Ahh
