Naruto's opening eternal eye

Mo Nan arrived a little earlier than the agreed time, and Kakashi came after a while, very punctual to the minute. It seems that he has not yet been affected by Obito and developed the habit of being late.

After the two met, they greeted each other and got straight to the point without talking much.

If you want to develop a new ninjutsu, Mo Nan must master a very high level of Lightning Chakra's nature changes. In order to improve efficiency, Kakashi decided to teach Mo Nan himself.

At this time, Mo Nan proposed that they could use the shadow clone to practice, so that when Kakashi taught Mo Nan Thunder Dun, only one shadow clone was needed.

And Mo Nan can also use the shadow clone to teach Kakashi Huo Dun, which will save a lot of time and greatly speed up the progress of cultivation.

Kakashi was amazed by Nan's fantastic idea, why didn't he think of using the shadow clone to practice before.

So each of the two separated into three clones, one of which helped the other to practice, while the main body and the other two clones practiced with the help of the other's shadow clone.

It's not like they can't create more shadow clones, like Naruto, they can create dozens or hundreds of shadow clones and master the changes in nature in a very short time. However, based on Mo Nan's experience in practicing with shadow clones during this period of time, it turns out that this is not necessary.

The reason why Naruto needs so many clones is because he is an idiot and has very few ideas in his mind, so he needs numbers to pile up his training experience. Moreover, because he has few ideas in his mind, he feels much less mental pressure after contacting the shadow clones.

But Mo Nan and Kakashi are different. Not to mention that they don't have as much chakra as Naruto, so it's difficult to separate so many clones. Secondly, they are both smart people. If too many clones are used, the complex thinking of each clone may overwhelm their brains after the ninja is released.

So after careful consideration, they decided to only use two clones to practice, which would also make it easier for them to maximize the training effect.

"Nan, first let me see how far you have cultivated your Lightning Tunnel nature change." Kakashi asked Mo Nan.

Mo Nan and Kakashi have actually practiced a bit in the past two months and made some progress. If Mo Nan's previous level was the Thunder Release and Spark Finger Technique, then his current level can be called the Thunder Release and Spark Palm Technique.

Mo Nan used his Spark Palm Technique on Kakashi, and he expressed satisfaction with his progress.

Kakashi looked at Mo Nan speechlessly, how could he still look proud when he had only mastered a little bit.

"Your Thunder Dungeon is very average, it can only be regarded as a beginner's level, and because we can't practice properly, we'd better start from scratch."

After hearing Kakashi's words, Mo Nan's face fell. He divided the training of Thunder Release into two stages according to the way Naruto practiced Wind Release in the original work, and made a plan to practice. He thought he had reached the first stage of cultivation, but he didn't expect that he was nothing in the eyes of experts.

Unaware of the change in Mo Nan's face, Kakashi continued to talk about the scene when he followed his father to practice Thunder Dun.

"Back then, I practiced Thunder Dungeon from scratch, and it took about three months to fully master it. This is already very fast."

Mo Nan curled his lips and thought, "I thought you were so powerful, but you are not as fast as Sasuke. I only used it for a month."

Of course, he didn't think about how old Sasuke was and how old Kakashi was when he was practicing Thunder Release.

"Judging from your current level, you will probably need half a year."

Kakashi saw Mo Nan's disdainful expression and couldn't help but hit him. In fact, what he was thinking was that Mo Nan, who was so smart, might be able to master Lei Escape faster than him.

When Mo Nan heard this, he became angry and thought, "Even an ordinary civilian genius like Sasuke, who only opened the Eternal Eye at the age of 17, only used it for a month. An invincible monster genius like me, who only opened the Eternal Eye at the age of six, didn't say that." It would take half a month to learn how to do it in one week, but you told me it would take half a year."

Although he thought so in his heart, Mo Nan still pretended to listen to the teachings on the surface. He could see that Kakashi was deliberately disgusting himself because he saw the disdainful expression he had just inadvertently leaked.

Sure enough, seeing Mo Nan's current expression, Kakashi was quite satisfied, and his mouth relaxed.

"Originally it took half a year, but because of your shadow clone training method, you may be able to master it within a month at the earliest with three people, the main body plus the clone."

Mo Nan almost spit out the fragrance. Could it be any more false? Half a year is six months, does six divided by three equal one? Mathematics education in the ninja world is so poor? But he didn't dare to show it anymore, he was afraid that Kakashi might have some other tricks to disgust him.

So he pretended to be happy.

"That's great. Let's put it this way, we may start developing new ninjutsu as soon as one month."

After that, the two began to practice step by step. During this period, Kakashi knew that Mo Nan had been using the shadow avatar to teach.

He was surprised that Mo Nan actually had two clones elsewhere. Knowing that his strength was close to that of a Jonin, it was very difficult for him to practice with three shadow clones. And Mo Nan can actually use five clones, and it seems that he still has some strength left.

And his surprise was deepened when he saw that Mo Nan still felt that his cultivation progress was slow and created a clone. The six shadow clones were twice as many as himself.

Although Kakashi knew that he belonged to the kind of ninja with less chakra, he still wanted to cry when he saw Mo Nan, who was only half his age, with twice his chakra.

The gap between the two is so big now, wouldn't it be even bigger in the future? When they both reach adulthood, how many times, four times, will his chakra be? Eight times? ten times?

Realizing that the gap between the two might be huge enough to make people desperate, Kakashi could only comfort himself silently in his heart with tears in his eyes, it's okay, the strength of a ninja is not determined by the number of chakras.

Mo Nan didn't know that Kakashi was hit hard because of his chakra, if he knew what Kakashi was thinking. He would definitely taunt secretly in his heart, "Huh, ten times? If my chakra does not reach a hundred times yours when I become an adult, I will take your last name"...

Day by day, the progress of the two people's cultivation was very fast, because Kakashi's level of Fire Dune was higher than that of Mo Nan's Lightning Dun, so Kakashi thought he had to wait for Mo Nan.

What he didn't expect was that Mo Nan was a little more talented than he thought.

Mo Nan's cultivation progress was faster than expected, not only because he used an extra shadow clone, but there must be talents beyond ordinary people's imagination.

This is what Mo Nan is thinking, but Kakashi will never admit it. This must be because he uses an extra shadow clone. Yes, that's right. It's not because his talent exceeds mine.

Soon Mo Nan's progress in Lightning Dungeon practice caught up with Kakashi's progress in Fire Dungeon practice, and even slightly exceeded it, which put Kakashi under a lot of pressure and had to redouble his efforts to catch up.

Three weeks later, Mo Nan completed the training one week earlier than expected. At this time, Mo Nan had completely mastered the changes in the chakra properties of Lei Dun. Kakashi also soon mastered the changes in the nature of Fire Release.

There is also an unexpected joy, that is, Mo Nan's shadow avatar was not idle when he was teaching Kakashi Fire Escape, he was also practicing while teaching Kakashi.

And it seems that Kakashi Shikage's avatar had a deeper understanding of Huo Dun, and Mo Nan found that his level of Huo Dun had reached the Jonin level in one fell swoop.

But this is just a matter of course and Mo Nan is not too excited. What makes Mo Nan most excited is that he, who has completely mastered the nature of Thunder Tunnel, can finally start the development of Thunder Tunnel Ninjutsu.

Mo Nan and Kakashi discussed it, and they decided to start the development of the new technique immediately without delay.
