In the courtyard of the Thousand-Hand Mansion, Xia Yan was still concentrating on constructing the rune technique of the Yin Seal in his body.

From the projection of the human meridians above the stone table, it can be seen that the chakra flow in Xia Yan's body and the transformation and connection of the Yin Seal runes are all proceeding in an orderly manner, and it seems that there is no major problem.

And Mito, who took in all of this, couldn't help but feel a lot of emotion in his heart.

After all, it was only two months ago that he handed over the scroll of the Yin Seal to Xia Yan.

Although he had repeatedly raised his evaluation of Xia Yan, he was still surprised that he had officially started the cultivation of the Yin Seal so quickly.

You must know that even if she is known as a genius in sealing techniques, it took a long time to reach the threshold of cultivating Yin Seals.

Although she also learned about the infant doppelganger technique from Kushina.

So she also knew that Xia Yan could make rapid progress at such an unreasonable speed, and at the same time take care of invention and creation. The secret of school, tavern, and so on.

Even with this Yin Seal, Xia Yan was actually able to enter the stage of formal cultivation so quickly with his infant clone and this special Yin Seal Meridian Scroll.

However, Mito did not lower his evaluation of Natsuhiko because he was using these "foreign objects", but appreciated him even more.

After all, even Tsuruma, who is known as the god of ninjas, can't tell where his unreasonable skills come from, let alone pass them on.

Therefore, although he was able to suppress the ninja world during his lifetime, no one disagreed, but after his death, he could only leave an invincible false name, and there was no one who could inherit his skills.

And a genius like Kazuma, although he has created a lot of ninjutsu, but it is also high and low, and few people can learn it.

Perhaps only Xia Yan, who came from an ordinary background and even had mediocre ninja qualifications, could use his intelligence to create a universal path that could be passed on stably.

It's like the special Yin Seal Meridian Scroll in front of you.

After Xia Yan's improvement, it can show the flow of chakra when constructing the Yin Seal Technique, and even the subtle changes when it is transformed into runes.

This also means that the Yin Seal cultivation method that cannot be spoken, can only be understood, and needs to be experienced by oneself through feeling has become a thing of the past.

Xia Yan, this kid, can quickly and intuitively grasp his cultivation situation at any time through this meticulous meridian system diagram, and even fine-tune the route of Chakra's operation.

In fact, after referring to Mito's own Yin Seal Chakra operation model, Natsuhiko has made certain improvements to the Yin Seal to make it more suitable for herself.

And this was also the reason why Xia Yan was able to start Yin Seal cultivation so quickly.

Because the Yin Seal is not as simple as a chakra container, when cultivating, it is necessary to extend the runes made into chakras along the meridian system to all parts of the body, so as to integrate the chakra of the whole body and prepare for various uses after the formation of the Yin Seal in the future.

In the past, this kind of operation of construction in the meridians would cause great damage to the meridians, and it was also a major difficulty in cultivating this technique. ….

Even the Uzumaki clan with rough skin and thick flesh needs to be proficient in medical ninjutsu, and they can treat themselves at any time before they are eligible for formal cultivation.

However, through this meridian scroll, Xia Yan was able to reduce the risk of this problem to an extremely low level.

Coupled with Xia Yan's surprisingly good chakra control, he dared to directly start the cultivation of the Yin Seal after just a rough and simple medical ninja.

Judging from the current situation, Xia Yan's alternative method should have been successful.

Moreover, this method is not only available to him, but also Kushina, and even Tsunade will benefit from it, thus greatly reducing the time it takes to practice the Yin Seal.

Mito once heard Natsuhiko say that he wanted Yin

Based on the seal, create your own Baihao technique.

There is no doubt that he has taken a very solid step forward today.

Just when Mito was looking at Xia Yan with a relieved expression, Xia Yan's cultivation also entered a critical juncture.

I saw that all kinds of wonderful lines began to appear on his body, and then these lines began to spread upward, and finally converged on his forehead, forming a purple diamond-shaped mark.

Immediately, both the lines and the diamond-shaped mark began to slowly disappear again, as if they had never existed.

Seeing this, Mito finally put down his last bit of worry and smiled with satisfaction.

It's done.

After exhaling lightly, Xia Yan slowly opened his eyes.

"Xia Yan, you are so powerful, you can succeed in one go."

"Yes, our ontology is far from perfect! I haven't learned it for so long."

A few Kokushina took the lead in cheering and ran over, chirping around Natsuhiko and talking.

And Jiu Sinai, who was also happy to follow the past, suddenly stiffened his face after hearing his doppelganger's speech.

It is true that he has been studying the Yin Seal for a longer time than Xia Yan, and the result is still at the stage of learning medical ninjutsu.

Although with the help of the meridian scroll, the requirements for medical ninjutsu attainments in cultivating this technique have been reduced a lot, but it can't be ignorant.

Moreover, Jiu Sinai, who has a very large amount of chakra, is also much inferior to Xia Yan in terms of chakra control, and he still needs to strengthen his training in this area in order to meet the requirements of formal cultivation of Yin Seal.

Although he understood that what his doppelganger said was the truth, Kusinai still said with an unconvinced face:

"Hmph, you guys wait, after I cultivate the Yin Seal, I will definitely catch up with Xia Yan soon!"

Mito looked at Kushina, who was fighting with him, angrily, and then looked at Natsuhiko, who was surrounded by Kokushina, and said:

"Actually, what Kushina said is not unreasonable, Natsuhiko."

"Although Xia Yan, you have already constructed the Yin Seal technique in your body, you can't take it lightly."

"After all, this second stage of cultivation is even more difficult than the first stage of cultivation......

Natsuhiko, who stood up and got rid of the entanglement of Kokushinai, also nodded slowly in agreement.

Although the magic lines on his body just now seemed to be gone, they were actually still working in his body. ….

And the second stage of cultivation is Chakra's savings, which need to maintain the operation of this Yin Sealing Technique all the time, and at the same time, it is necessary to continuously inject Chakra into it.

If the first stage of cultivation is to create a container for chakra, then the second stage is to fill this container with chakra.

In a sense, this is actually very similar to the idea of the human pillar force using the body to seal the tailed beast.

It's just that the Yin Seal seals its own chakra.

Moreover, because the chakra needs to be continuously injected into the container, the Yin Seal does not operate on its own once it is generated like an ordinary seal, and the cultivator needs to be distracted to maintain the operation of the Yin Seal Technique at all times.

And this is where the difficulty of the second stage of cultivation lies, because once the distraction is not maintained, it will be wasted and you will need to start from scratch.

Therefore, whether it was eating, sleeping, or fighting, the cultivators were distracted to maintain the existence of the Yin Seal.

It wasn't until the chakra was filled up and the purple diamond-shaped mark was completely formed that the Yin Seal technique was completed and could work on its own.

Moreover, this technique takes the form of a piecemeal deposit, as long as it is not fully formed, it is impossible to temporarily take out the chakra and use it.

Because of such harsh conditions, although the Yin Seal is very powerful, it is a secret technique that only a few people can learn.

Not to mention that Xia Yan still has a big shortcoming in his cultivation at all stages.

- That's the amount of chakra he's always been barren.

Originally, in the infant doppelganger and various research activities, he

has been using all his chakras every day without hurting his body, and he can't wait to use one chakra as two.

Now that there is a big Yin Seal, it makes his chakra even worse.

Even Mito couldn't help but ask again:

"Xia Yan, are you sure you still have to follow your previous thoughts, and only allocate so little chakra to the Yin Seal every day?"

"At this rate, I'm afraid it will take you more than ten years to fill the Yin Seal."

Mito is already a very optimistic view.

After all, in such a condition where slackening will be wasted, the longer the time is delayed, the higher the chance of accidents.

Moreover, with the increase in the amount of chakra in the Yin Seal, the chakra and energy required to maintain the technique will also increase, and the requirements for the chakra control power of cultivating this will also continue to increase, so the idea of long-term battle is very undesirable.

It's just that Xia Yan didn't plan to spend more than ten years to learn this technique.

Now symbolically injecting chakras into the Yin Seal to keep it running, just to train yourself.

So he just smiled and said:

"It's okay, teacher."

"For this stage of cultivation, I actually already have certain ideas."

This time, Mito could probably guess Natsuhiko's interruption.

Since it is too slow to rely on one's own chakra, it is natural to think of the means of absorbing chakra from the outside world.

The most direct way to do this is to add a chakra source to the body, such as a tailed beast or something.

However, unless a reconciliation is reached with the tailed beast, under the interference of the tailed beast, I am afraid that the Yin seal will never be able to form.

Otherwise, although it is very rare, it has always been rumored in the ninja world that it can absorb the secret art of chakra.

It's a pity that for Mito, who was born in the Uzumaki clan and married into the Senju clan, he naturally doesn't need to say much, and even the people around him have never encountered a lack of chakra.

Those with less than ten chakras are embarrassed to say hello to others.

So she didn't have this secret technique that could absorb chakra.

So Mito stroked his cheeks again and said sadly:

"It's a pity that the people of our clan have been scattered all over the place, otherwise we might be able to provide you with a little help Xia Yan......
