Seeing Sasuke like this, Naruto couldn't help but laugh.

It's so much fun to pretend that nothing happened and relieve yourself of embarrassment.

And at this time, Sasuke realized that Naruto knew everything, and knew that he would definitely challenge himself after practicing the electromagnetic cannon technique, and he was deliberately teasing him.

"Naruto, you!"

Sasuke pointed at Naruto, wanting to spit out the fragrance.

But after measuring the difference in combat effectiveness between the two sides, he held back.

After finishing with the Great Sasuke Skin, you can find Naruto to treat him, but if you follow Naruto Skin, then no one will treat him.

He didn't want to delay his cultivation time because of this, and then he would only be widened by Naruto, who had also been working hard, to widen the gap between the two.

"Hahaha, okay, okay, no kidding, I learned the electromagnetic cannon technique that you worked so hard to research, so in return, I'll teach you a new ninjutsu, immortal mode, do you want to learn?"

After laughing, Naruto said seriously.

Although he had planned to let Sasuke, a tool man, help develop the electromagnetic cannon technique from the beginning, Naruto didn't intend to treat his friend badly, and had already thought of a compensation plan.

If it weren't for Sasuke's death last time, he would have taught Sasuke the immortal mode a long time ago, and now he would be teaching a more advanced Yin Yang Escape.

And Sasuke, who didn't know this, was a little surprised at this time: "The one who can use natural energy?" ”

Watching Naruto cultivate immortals every day, he knew how powerful the increase in immortal mode was on strength, but Naruto only let him focus on the development of the writing wheel eye and electromagnetic cannon technique before, and did not plan to teach him to cultivate immortals.

"Hmm."

Naruto nodded.

I didn't teach Sasuke Senjutsu before, because he couldn't learn it at all.

Practicing immortal arts requires an ethereal state of mind, and you can guard against arrogance and rashness, but a few years ago, Sasuke was full of impetuousness caused by the total destruction of his parents and relatives, and the ancestral paranoia of the Uchiha family.

In such a state, even if Naruto taught him immortal arts, he wouldn't be able to learn it.

It's not that with Sasuke's talent, he can't control the immortal chakra, but he can't perceive natural energy at all in such a state.

And in recent years, with Naruto's occasional beatings and help, Sasuke has absolute confidence that he can take revenge, the impetuosity in his body is disappearing, and there is no room for paranoia to survive.

With the continuous exchange of chakras with Naruto, Sasuke's physique is also changing in the direction of the immortal body, and under the harmony of yin and yang, this also fundamentally changes the paranoia brought about by Sasuke's extreme yin attribute as an Uchiha.

In this case, after the development of the electromagnetic cannon technique, the next step is to cultivate immortals, which will become a new direction for Sasuke's rapid growth in strength.

"Then what are you waiting for, go back and cultivate immortals." Sasuke said eagerly.

"Hmm."

Naruto nodded, and led Sasuke to the bottom of the waterfall where they usually practiced.

Here, Naruto began to teach Sasuke the Senjin Mode, which was no different from the previous process of teaching Terumi to practice senjutsu, but there is no need to repeat it.

It's just that Sasuke, who has been guarding against arrogance and rashness, has made progress in practicing immortal arts faster than Terumi Ming, I don't know how much.

Under the guidance of Naruto, a master of immortal arts, Sasuke learned the immortal mode faster than Naruto at the beginning, and it only took two weeks to be able to enter the immortal mode independently.

After all, Sasuke at this moment is much stronger than Naruto, who was a beginner in immortal arts at that time.

If it were Naruto now, it wouldn't take a few days to cultivate immortal arts.

And with the blessing of Sasuke's own ultra-high chakra control ability, by the time of a month, he was able to skillfully apply the immortal mode to battle.

Of course, if you want to be able to enter the immortal mode in seconds like Naruto, it is not a matter of talent.

Next, what is needed is to rely on time to run in, so that the body can more fully and thoroughly adapt to the existence of natural energy, so as to reach the realm of immortal mastery, and the mind can enter the immortal mode with a single movement.

And if the talent is not enough, this run-in period is likely to be a lifetime.

Of course, for Sasuke, there is no such problem.

While Sasuke was practicing senjutsu, Naruto was also observing the changes in his body and found that his guess was indeed correct.

After practicing in the immortal mode, Sasuke's physique is changing faster to an immortal body like him, and after a long time, he will completely transform into an immortal body.

When the time comes, Sasuke will not only have a large increase in the amount of chakra.

Even if you evolve your own writing wheel, you no longer need to fuse the pupil power of your blood relatives to evolve into an eternal kaleidoscope writing wheel, but you can naturally evolve into a kaleidoscope writing wheel like Naruto.

At that time, Sasuke's comprehensive strength will improve by leaps and bounds, and he will steadily reach the strength level close to the six realms.

Of course, it is no fun for Sasuke's chakra to reach the level of Naruto, his huge chakra is not only the credit of the immortal body, but also the credit of the nine lamas' long-term nourishment from the chakra and his own hard work.

However, in the end, Sasuke's chakra should be able to reach 60% of Naruto's, which is also much stronger than now.

Successively practiced the electromagnetic cannon technique and the immortal mode, which made Sasuke have a great degree of confidence in his strength, although he still did not have any confidence in challenging Naruto, but another thing was already full of confidence.

In the fourth month of practicing the Electromagnetic Cannon Technique, the third month of the Immortal Mode, Sasuke, who felt that his cultivation of these two ninjutsu had temporarily reached the limit of the current stage, found Naruto.

Under the waterfall, Sasuke said very seriously, "Naruto, I plan to set off tomorrow to find out the traces of Itachi, and go to him to find out what he really thought at that time." ”

"As I once said, if he has a hard time, then let him go with me to find the masked man to avenge his parents and relatives, if he is just in pursuit of a more powerful pupil power, then kill him first, and then go to the masked man to avenge him."

"I'll take revenge myself, but I have to make sure that no one interferes with my fight with Itachi."

"So, help me, Naruto!"

Looking at Sasuke, who was stretching out his hand towards him, Naruto didn't hesitate, and without hesitation, he stretched out his hand and held it: "Okay." ”

Seven years ago, also under this waterfall, the young man in front of him, his only friend.

Reaching out to Naruto, he told him that he wanted to get stronger and asked him for help.

In a blink of an eye, seven years have passed, they are no longer the weak they once were, their strength has changed dramatically, and they can even determine the future direction of this world.

It's just that although seven years have passed, they are still friends.

Naruto hoped that even seventy years later, they could still be friends.
