Naruto, the time-traveling Naruto has an incredible understanding!.

In Naruto's memory, Sasuke mastered Lightning Release after he graduated and became a Genin.

Six years later, under the guidance of Kakashi Hatake, he mastered the Lightning Release: Chidori.

At this time, the jumping lightning in Sasuke's hand had obviously mastered the attribute changes of Lightning Release.

Sasuke, how old are you!?

Less than six years old!

It seemed that his training with Sasuke had led to some special changes.

"Ok!"

"Unmarked Lightning Release."

"I haven't figured out what to call this lightning escape yet."

"However, I can't inject too much chakra now, otherwise I will get hurt myself."

"Naruto, do you have any suggestions?!"

"Even though you're just a big fool, I still believe you can give me some good advice."

Sasuke spoke proudly.

I have to say that Sasuke has now begun to evolve into a tsundere.

"Any suggestions?!"

Naruto really thought about it seriously this time.

[Ding, the host seriously thinks about the information about Lightning Release and comprehends Lightning Release: Chidori Style]

[Ding, the host is seriously thinking about the development of Lightning Release, and comprehending Lightning Release·Thunder God Body]

The most profound memory in Naruto is about Lightning Release.

It is the Chidori Style and the Raikage's Thunder Armor.

Just as I was thinking about it, the system prompt sounded.

This incredible comprehension ability is truly powerful!

"Sasuke, I think that if you want to develop Lightning Release, the first thing you need to do is to make yourself strong enough to master it."

"And the fastest way to achieve this is to undergo lightning immunity training."

Naruto spoke in a serious tone.

"Lightning Release immunity training!?"

"what is this?"

Sasuke had a cute look on his face, tilting his head and looking at Naruto curiously.

Naruto is obviously a big idiot, why can't he understand what this guy says! ?

Sasuke was a little confused.

"it is this……"

"Zizzizi..."

"Ah ah ah..."

As Naruto spoke, a ball of lightning appeared in his hand and fell directly on Sasuke's hand.

Because the lightning in the two people's hands were entangled together the moment they came into contact, triggering a chain reaction instantly.

The next moment, Sasuke and Naruto both screamed.

The body also began to tremble.

"boom!"

Uchiha Mikoto pushed the door open immediately.

It looked like the two little ones had separated.

However, at this time, both of them were emitting black smoke and their hair was standing up.

There is even residual current jumping around!

"Sasuke, Naruto!"

Uchiha Mikoto rushed to the two of them and picked them up.

Quickly went to the hospital.

Fortunately, both of them have strong physiques.

That level of lightning escape can only shock them unconscious.

Even Naruto woke up after being dizzy for a moment.

Of course, Naruto can't wake up immediately, he still has to go to the hospital.

In the hospital ward.

Sasuke regained consciousness after a simple treatment by the medical ninja.

He subconsciously looked at the bed next to him, and grinned at Naruto who still had his eyes closed.

Children's minds are always so pure and simple.

"Are you laughing at me!?"

After sensing that Sasuke had woken up, Naruto also opened his eyes and spoke seriously.

"No, I just feel like I've been infected by your stupidity."

"But what you said seems to be true."

Sasuke said, raising his hand.

A ball of lightning appeared again.

However, after just one electric current attack, the electric current that Sasuke now controls has become much stronger.

"And you still call me stupid!?"

"Sasuke, if it weren't for me, would you be able to find such a way of training!?"

"By the way, there are still many things we need to learn about Lightning Release."

"Recently, you can ask your brother or father to teach you."

"Then you teach me."

Naruto spoke cheerfully.

"But……"

"If we continue this way of training, will we keep running to the hospital next time!?"

"But if I can keep improving like this, it seems like it's okay."

Sasuke smiled innocently.

Indeed, this is just a one-time upgrade!

Next, continue to practice like this.

Sasuke even felt that he would definitely be able to graduate early.

Although it is not a war period now, it is generally not possible to graduate early.

However, if a student is good enough, he or she can apply.

"Why don't we learn some medical ninjutsu?"

"I will be responsible for learning these, and you will be responsible for learning Lightning Release."

"Then, we just need to cooperate and that's it."

Naruto said with a smile.

Sasuke was stunned when he heard this.

He always felt that there was something wrong with what Naruto said.

But...it also seems to make sense.

"Ah."

"How about...try it now?"

Sasuke said, dropping the lightning in his hand directly on his chest.

"Zizzizi..."

With the "nourishment" of lightning, Sasuke successfully fainted again.

Naruto was speechless looking at Sasuke like this.

What a good fellow, he is so cruel to himself? !

Naruto slowly stood up and walked over to Sasuke's bed.

That's right, Naruto no longer needs to learn this medical ninjutsu.

When the medical ninja was treating Sasuke and him just now, Naruto had already mastered the great package of medical ninjutsu.

With his current chakra control and chakra amount, he could already perform some basic medical ninjutsu.

He stretched out his hand, and a ball of green light lit up in his hand.

Sasuke's breathing slowly became smoother.

Ten minutes later, Sasuke's eyelids twitched, and then he slowly opened his eyes.

"Naruto, I..."

"I was unconscious for about twenty minutes."

"Yes, it seems that the method I mentioned is feasible."

"Through this kind of stimulation, Sasuke, you will be able to fully master the changes in the attributes of Lightning Release sooner or later."

"When the time comes, you can use your understanding of Lightning Release to develop a fighting method that best suits you."

"I seem to have seen a genius who is about to become a super strong man!"

Naruto gave his thumbs up.

The overflowing words were output quickly, as if they were free of charge.

Sasuke, who was already a little proud, became even more proud.

The best one is rising, and even Shinra Tensei may not be able to suppress it.

"Okay, I'm not as good as you say."

"By the way, Naruto, we have recovered now, can we go back?!"

Sasuke asked curiously.

He doesn't like the hospital environment.

Moreover, if such an experiment was seen by the medical ninja in the hospital, he would definitely tell his mother.

Then, you will be scolded.

"Ah."

"Let's take a break and then go back."

Naruto nodded and went back to his bed.
