After two or three days, Sasuke had gradually adapted to the current chakra.

The skills obtained in Teyvat are quite special, Sasuke can't adjust these skills, basically consuming a fixed proportion of chakra, and the power will basically only increase with the increase of the upper limit of his chakra, and he can't optimize those skills too much, which can be regarded as ensuring the lower limit, but it also seals the upper limit to a certain extent.

This also made Sasuke realize that the ability to acquire other people's skills, although it is indeed useful at this stage, should not be relied on too much.

After his regular training, Sasuke proposed to Kakashi advanced training, that is, training in extreme environments.

Artificial obstruction by Kakashi using ninjutsu, including but not limited to strong winds, miniature earthquakes, and waterfall washing.

It's a bitter thing for Kakashi.

Because of the writing wheel, he didn't have much chakra he could use, and Sasuke was extremely tenacious, and he didn't stop at all until Kakashi's chakra was completely drained, gritting his teeth and carrying it.

After staying up like this for a week, Sasuke gradually adapted to the rhythm of chakra use in extreme environments.

Sakura was amazed by Sasuke at this time.

In the first few days, she was able to continue training chakra, and in the next few days, she basically only came to visit Sasuke at the end of training.

She flinched a little.

Now she is just a carefree little girl with a happy family, without so much pressure and motivation.

The love for Sasuke is more about the little girl's longing for Brother Ku, but it is still a little difficult for her to really move forward side by side.

Even if she really likes him.

But the gap between people is sometimes really bigger than the gap between people and dogs, and even Sakura is considered an honor student in the ninja school.

Naruto gritted his teeth and persevered, even though there were many complaints in between.

He often said 'I won't come back tomorrow, I'm going on a mission with Sakura, going on a date', but the next day he still showed up in the back mountain with Sasuke on time for training.

And Kakashi was also surprised to find that Naruto Uzumaki was improving and adapting faster than he imagined.

But also, after all, he is the son of his own teacher.

It's just that at every critical moment, his chakra will have some mistakes, and Kakashi is estimated to be because of the influence of the Nine-Tails in his body.

But Kakashi couldn't help Naruto too much in this regard.

He's not a very good person at teaching, and he can adapt to someone like Sasuke, who is talented in his own right, and he can understand everything, but for Naruto......

Maybe if Obito is still alive, he should be able to have some common language with Naruto.

At the end of the day's training, Kakashi found the Miyome Hokage.

"You want me to find another suitable mentor for Naruto to train in?"

In the Hokage's office, Sarutobi was smoking a cigarette and looked at Kakashi and said.

"I think you're bringing it well, why do you suddenly say that."

"Naruto is very talented, but I'm not suitable, the ninjutsu I know requires too much chakra control accuracy."

Kakashi said.

"And it's about to take the Zhongnin exam, this Zhongninja exam is still a multinational joint examination, I hope they can all improve and go further."

"I'll do a special training session for Sasuke next, but Naruto...... It may not be possible to participate. ”

Sarutobi was silent for a moment, glanced up at Kakashi, and then tapped the pipe in his hand.

"I see."

He bowed Kakashi and walked to the window of his office, looking out over Konoha Village.

Previously, he dismantled Cardo's group, secretly received a large amount of Cardo's property, and controlled the country of waves, helping the country of waves to complete the construction of bridges, which increased a lot of prestige.

Under this operation, the financial pressure on Konoha Village has been eased, and everything seems to be thriving, but there is still an invisible undercurrent surging under this prosperous scene.

Tuan Zang seems to be getting more and more uncontrollable, and a certain amount of suppression is needed.

It's time to call back Jiraiya, it just so happens that Naruto also lacks a suitable candidate to guide, and the matter of Sasuke Uchiha ...... He also needed someone on his side to stand on the platform.

……

A day later, Konoha back the mountain.

At this time, only Kakashi and Sasuke were left in the back mountain.

Kakashi was explaining today's training to Sasuke.

"This ninjutsu is a high-speed piercing technique that can only be completed with the prediction and cooperation of the writing wheel eye."

"Chidori."

"And in addition to writing the wheel eye, you need the corresponding physical skill foundation, as well as the explosive power to increase the speed in a short period of time, so now you need to rely on the assistance of the eight Dunjia to use this technique."

"Eight Gate Dunjia?"

Sasuke asked.

"Yes, Bamen Dunjia, this technique can temporarily gain powerful power by unlocking the channel that binds Chakra in the human body, but the side effects of this ninjutsu are too great, and it can burst out with very terrifying power when the eight doors are fully opened, but opening the eight doors also means burning your own life."

"While gaining power, the caster himself will be damaged, so this technique is listed as one of the forbidden techniques."

Kakashi's expression was solemn as he said this.

He had really seen the power of the Eight Gate Dun Armor and the backlash.

"Therefore, I will only teach you the first of the eight Dunjia, open the door."

"Opening the door can remove the restrictions of your brain domain to achieve the goal of 100% physical ability."

"Of course, that's in a real combat state, this one will be released first, and you need to learn to release Chidori first."

"Look at it, Sasuke, concentrate the high-intensity current formed by the Thunder Chakra in your hand."

Kakashi raised his arm, and the thunder light condensed on his palm, and then at a great speed, he rushed forward.

So fast!

Sasuke turned on Sangotama's writing wheel to keep up with the speed at which Kakashi moved.

It's no wonder that the prerequisite for this technique is to have a writing wheel eye, and if there is no cooperation with the writing wheel eye at this speed, the surroundings will become blurry, and it is estimated that it will be difficult to hit.

Syllable!

A huge groove appeared in a rock wall that had been hit by the lightning light in Kakashi's hand.

Sure enough, it's a very powerful ninjutsu!

……

......

After most of the day's attempts, the thunder light in Zuo's assistant has already had a little rudiment, but it can't be fully controlled, and it can't be well contained, and from time to time there will be electric light overflowing from his hands.

Multiply...... Multiply......

In a distraction, a trace of lightning leaked out from Zuo's assistant, cutting through his clothes and leaving an electric mark on his arm.

"Are you alright? Do you want to take a break first? ”

Kakashi stepped forward to check, and the location of the lightning light hit was right near Sasuke's wound earlier.

Sasuke covered his wound and made no sound, and after half a minute he said:

"It's okay, minor injury, let's continue."

The thunder light in his hand reappeared.

Paimon was still waiting for him to appear, how could he stop because of this little injury.
