During this battle on the back of the dragon, Sasuke discovers a large number of flaws in his body.

After entering Teyvat, his chakra volume has been greatly improved, and his pupil power has also been increased due to various coincidences, on the surface, his strength has indeed become a lot stronger, but this power is too vain.

He didn't have full control over the force, especially in a high-pressure environment.

When Stormterror flew up and down, he was completely unable to control his chakra, which led to Susa's disappearance and finally affected the balance of the battle.

If he had been able to take full control of his chakra at the time, Paimon wouldn't have ......

Precipitation.

He needed someone to guide him to become fully acquainted with his own strength, not to hold a mountain of gold and go home empty-handed.

At the same time, he needs more offensive means.

Although Susanenghu is powerful, it can indeed burst out with extremely strong combat power in a short period of time, but the consumption and negative effects are too strong.

For my current self, it can be used as a killer move, but it can't be used as a conventional means of attack.

And his regular offensive means are somewhat lacking and need to be strengthened.

A few Fire Escape Ninjutsu and Wind Breath Agitation are more suitable for mid-range use, and although there are Wind Vortex Sword obtained in Teyvat, as well as Frost Attack and Frost Wheel Dance obtained by Kaiana, these skills are not comprehensive enough to cope with more complex combat environments.

Teyvat can give him power and various magical skills, but the power system is completely different from his side, so he needs Kakashi's help.

"Oh?"

Kakashi sideways.

"It's really rare, didn't you go home alone to cultivate after you completed the task before?"

Sasuke gritted his teeth, because of Teyvat, he felt that as long as he relied on Teyvat, he could quickly gain strength, so he barely consulted Kakashi about his cultivation.

Now that he was stuck at Teyvat, he ran over to Kakashi for help......

But now was not the time to be ashamed, he bowed his head and continued in a very sincere tone:

"I need more strength, I need strength that can make the difference between victory and defeat."

"Please help me, please."

Is this something that Sasuke Uchiha would say?

Kakashi was a little surprised.

He had the impression that Sasuke had always been that kind of very stinky little ghost, but now his tone was ...... Even a little humble.

But compared to that arrogant imp, Sasuke's appearance is undoubtedly a little more likable now.

And as a mentor, being relied on by students is undoubtedly a very rewarding thing.

"Well, I have a ninjutsu here that is perfect for you."

"When you're back and you're able to be discharged from the hospital, come to me."

"Remember to call Naruto Sakura with you, they came to visit you a lot when you were asleep, and the fruits in your ward were all bought by Sakura."

"Oh, you don't need me to say that you should know who brought it...... However, it is best not to eat this kind of fast food when you wake up. ”

A few days later, Sasuke left Konoha Hospital.

As for the reason for his injury, Sasuke explained that he had cultivated too much, was too tired, and did not control the release of ninjutsu well, which hurt himself.

He didn't reveal to Kakashi about his advanced Sharingan, on the one hand, because he felt that although Kakashi had Sharingan, he was a foreigner after all, and he might not know anything about this advanced Sharingan, and on the other hand, he was also wary.

It was only after awakening the advanced Sharingan that he realized how powerful this power was.

This also made him realize that there might be something strange about the night of the extermination, and it might even be related to the power of the Sharingan.

Maybe he was also involved with Konoha's higher-ups, although it was just speculation, but he didn't intend to expose it until he fully mastered this power.

The lesson Paimon's injury taught him is that he needs to be cautious in everything he does, and acting impulsively may not only hurt himself, but also implicate those around him.

If he hadn't had his self-confidence at the time, and had chosen to gather more information before fighting Stormterror, Paimon wouldn't have ......

The injury on his arm is basically no longer serious, and although his pupil strength has not fully recovered, it can only be done slowly, and lying in a hospital bed all day has no effect.

In the days since he woke up, Sakura and Ino have been harassing her hospital room almost whenever they have time, and he has been so annoyed that he even feels that he might as well stay in a coma until he is discharged.

Naruto's guy was okay, he only came over once, and he didn't make much noise.

In fact, Naruto in Kakasina secretly made up his mind to catch up with Sasuke after learning that Sasuke had been admitted to the hospital because of his excessive practice.

After all, Sasuke is a genius and works so hard, he has put himself in the hospital, if he wants to be recognized by Sasuke, how can he continue to be a child.

……

In the back mountains of Konoha Mountain, Kakashi guides Sakura, Sasuke and Naruto in the training, and the theme of the practice is the control of the chakra.

After briefly explaining to the three of them how to control Chakra, Kakashi asked the three of them to start doing tree climbing training.

To Kakashi's surprise, the best result in the first round turned out to be Sakura, the most inconspicuous of the three, and she easily climbed to the target position.

Then Sasuke, and finally Naruto.

Although Naruto has been training hard recently and has strengthened his control over Chakra, because of his special physique, the control is much more difficult than expected.

For example, if chakra is compared to water, then controlling chakra is like pouring water out of a water cup.

Take a small glass of water, pour out a third, be a little more careful, practice a few more times, and it is relatively easy to do.

But what if a pool of water is poured out exactly one-third of it?

Or ...... How about a one-third of the water in a lake?

For those who have a huge chakra...... No, it can be said that Naruto of "Chatara" is much more difficult to control the output of chakra than other ordinary ninjas.

And Sasuke is in a similar predicament, Teyvat's elemental power mixed chakra greatly increased the upper limit of his chakra amount, but it did not improve Sasuke's ability to control chakra, he still used his power in the same way as he used to control chakra, so naturally it became no longer suitable.

Plus he recently met Wendy.

With Wendy's blessing of a thousand winds, Chakra recovers much faster than he can use, allowing Sasuke to use Chakra almost infinitely under the blessing.

This made Sasuke even more neglect of his skills in controlling chakra, which led to him being very rough and rough in controlling chakra.

It may not be a big problem in an environment of equal strength, but once it is in an extreme environment, it will be exposed.

Kakashi immediately let Sasuke and Naruto complete their training after noticing Sasuke and Naruto's problems in this regard.

On the first day of training, the two spent almost all of their time in the cycle of climbing trees, falling from trees, hoeing the ground, then climbing trees, dropping again, and hoeing the ground.
