Naruto: The Strongest Sage.

After returning home and having enough food and drink, Karin actually asked to go to the basement to study. This made Aoba's heart move.

Then the two of them came to the basement. This was a place that was isolated by Aoba using various sealing techniques. Whether it was the telescope technique or White Zetsu's peeping, it was impossible to see here.

"Brother Qingye, I found something very strange. There is a monster you mentioned, and it has been near our house recently."

"Near us?"

Qingye's heart moved slightly. He realized that he had overlooked a problem. He didn't worry about White Zetsu's spying before. Because he was just a nobody at that time. At this stage, there are only a limited number of active White Zetsu, and it is impossible for them to waste their energy on him.

But with his defeat of the Raikage, the Wind Chaser has become the most famous figure in the ninja world. This will naturally attract the attention of White Zetsu.

Fortunately, Qingye's important experiments were all conducted in an isolated laboratory. Bai Zetsu could not detect it, otherwise, who knows how many variables would arise.

"Where is it now?"

"I can't see it now. But when I came back just now, it was right below our house, only about ten meters away."

Qingye understood. He probably had noticed his secret laboratory. He would be curious about this place that was blocked by the sealing technique and he couldn't see it. So, it was very close to the ground now. He wanted to know what this famous ninja was doing in secret.

"Very good, Karin. Remember, don't pay too much attention to this matter. Except for determining its location, don't pay too much attention to that guy at other times. Also, when it gets close to our floor, tell me."

"I see." Karin was a little excited. Children are always interested in ninja games. Children who haven't graduated always fantasize about becoming a great ninja after graduation and galloping on the battlefield. But in fact, there is no ninja who doesn't miss his school days.

Ninja games are never children's games. They are death games intertwined with iron and blood.

After the New Year, during the last few days of the holiday, Qingye thought of an appointment he had not fulfilled.

Outside the village, by the river, Uchiha Sasuke was already waiting impatiently. He even had the thought that he might be lying to me.

Before the New Year, he met Qingye. Qingye made a very strange request to him, which was to hold a banquet in the Uchiha family before the New Year and invite his classmates who were on good terms with him.

Sasuke had never seen such a weird request in his life. He even felt like the other party was deliberately making things difficult for him. Because everyone in Konoha knew that he was not sociable. But that guy insisted on asking him to do this.

But the technique that could kill Uchiha Itachi was too tempting. Although Sasuke was arrogant, after practicing with Aoba several times, he realized very clearly that he was still very weak.

It was impossible for him to kill Uchiha Itachi at this rate. Under the control of revenge and some other inexplicable emotions, he finally had the gathering at the Uchiha mansion a few years ago.

Although Sasuke was on pins and needles and extremely embarrassed during the whole process, how should I put it, thinking back on it later, it unexpectedly felt pretty good.

And since then, he seemed to have become closer to those classmates. During the New Year, many people sent New Year's gifts to his family. In short, Sasuke had a surprisingly good New Year after the disappearance of the Uchiha clan.

He also discovered a very 'terrible' fact: he didn't seem to hate the feeling at parties.

I shook my head and threw away the mess. What am I thinking? I am the last Uchiha. A man with a blood feud. How can I indulge in such childish play?

"What are you thinking about, Sasuke?" a question suddenly came from behind.

"Let's think about the next time we get together." Sasuke regretted it right after he said it. He turned around suddenly and found Aoba smiling at him from behind.

"Oh, it seems that the last gathering was quite effective. Let's keep up the good work."

"That's enough. I have fulfilled your request. Now you should fulfill your promise." Sasuke tried to act cool. But in Aoba's eyes, this was just a child's play.

"Well, I will not go back on my promise to you. Today I am here to fulfill my promise. I remember that you have the dual attributes of lightning and fire, right?"

"Yes."

"That's good. My technique is a lightning-style ninjutsu."

"Lightning escape?" A trace of doubt flashed in Sasuke's eyes. Because according to his intelligence, Aoba is a wind escape ninja, good at wind-based ninjutsu.

"Haha, we are Ninja Sasuke. You must remember to always keep a trump card for yourself. A trump card that can help you turn the tables at the critical moment of life and death. Only in this way can you be a true ninja."

"Trump card? I understand."

"Very good, now let's officially begin. Before learning this technique, there is a prerequisite. You need to be proficient in the changes of lightning chakra."

"Chakra changes?" Konoha's ninja school would never teach such advanced knowledge. In fact, at Sasuke's age, it was a little early for him to learn this.

If it was someone else, Aoba wouldn't teach like this. But Sasuke doesn't care. As the reincarnation of Indra, he is one of the two biggest hangers-on in the world. So, it doesn't matter if he squeezes a little more.

Sasuke always thought he was a genius. In the ninja school, he was the first in all the practical courses. To him, those things were very simple and easy to understand.

But after he started learning Aoba's ninjutsu, he felt for the first time what difficulty was. Difficulty beyond imagination. For three consecutive days, he practiced desperately, but he couldn't even complete the so-called chakra attribute change.

In other words, he was not even qualified to learn that technique. This made Sasuke a little frustrated. But at the same time, he was somewhat relieved. Because in his opinion, the more difficult this technique was, the greater the possibility of defeating Uchiha Itachi. He now believed that Aoba had not deceived him.

In fact, for Aoba, Uchiha Sasuke's progress is already amazing. To release conventional ninjutsu, you need to condense chakra and then make a seal.

The process of forming hand seals is actually the process of transforming chakra into ninjutsu.

But Aoba's ninjutsu does not have seals. In fact, all the ninjutsu developed by Aoba himself are sealless ninjutsu. Because the development of seals is a very dangerous thing. Even if you can see the effect of each seal. But once they are combined, they may not achieve the desired results. It may even cause backlash.

Therefore, developing a ninjutsu with seals is a very dangerous thing. Here we have to talk about the second generation Hokage, Senju Tobirama. This guy has all kinds of forbidden techniques, and he didn't die during the whole process, which really made Aoba a little bit difficult to understand.

But he himself would not take such a risk. Apart from the already formed ninjutsu, he would not cast a seal if he could not cast a seal on the other ninjutsu he developed. In fact, Aoba's bottom line was one seal.

In other words, the ninjutsu he developed could only form one seal at most.

At the moment, he was teaching Sasuke his own trump card ninjutsu, Lightning Release. Flash, which was the ninja world's version of a certain railgun.

The principle of this technique is to use lightning to create an electromagnetic acceleration track, and then launch the iron ball. As we all know, electromagnetic acceleration consumes a lot of energy. Therefore, this technique also consumes a lot of chakra.

The most important thing is that Qingye found that he had no chance to use the seals in Naruto to complete the two changes of electromagnetic conversion and acceleration. Even if he could, he felt that he would need at least twenty seals.

Such complicated ninjutsu is pure nonsense in actual combat.

So Qingye used a dumber but simpler method. He used his super strong chakra control ability to forcefully complete this series of changes on his hands, and then directly launched the metal ball.

Without the seal, the transformation of lightning attribute chakra must be completed, and at the same time, the electromagnetic conversion and the launch procedure must be completed. The whole process is not a question of whether it is difficult or not. It is simply too damn difficult.

Even someone like Aoba, whose mental power was extremely strong and whose chakra control was almost like cheating, took several months to barely complete the whole process.

It was a year later that it could be used in actual combat.

Even so, it was still not fast enough in Qingye's opinion. When he could perform this move as Pao-jie did, it would be considered a real success. Moreover, this move consumed a huge amount of chakra. He could not use it many times. At present, it could only exist as his trump card.

While Sasuke was practicing, Aoba was also training himself. He was practicing the Rasengan. He was not afraid of the Third Hokage seeing him, and he even did it on purpose for him to see.

Rasengan is an S-level ninjutsu. It's not because this jutsu is difficult. In fact, the principle of this jutsu is very simple. It is many times simpler than Aoba's flash.

The difficulty of this technique lies in the control of chakra. By this calculation, Aoba's flash is probably more than twice as difficult as the Rasengan.

Because the original Rasengan did not have any chakra attribute changes. It was just a highly compressed chakra ball. However, Aoba's Flash required a change in chakra attributes to get started, and its difficulty was really sky-high.

However, once this technique is used, its power is beyond imagination. An iron ball is accelerated to a speed of Mach 10 or even higher in a very short period of time. Its penetrating power is beyond description.

Aoba developed this move to deal with the Uchiha clan's Susanoo. After all, that thing is almost absolute defense. Once it is activated, conventional ninjutsu can't even knock it off.

However, Susanoo is huge and relatively slow in movement, making it an excellent target for electromagnetic cannons. In this respect, this move is also very suitable for dealing with Uchiha Itachi. However, the prerequisite is that Uchiha Itachi must use Susanoo.

Of course, this trick is also true for the tailed beasts. The tailed beasts are huge and basically cannot dodge this high-speed ninjutsu. The effect should also be good.

In fact, this technique has another use, which is sniper.

There are many long-range ninjutsu in the ninja world. But Aoba has not found this type of super long-range sniping. Back then, Minato Namikaze was somewhat similar. But he essentially flew over and ambushed people.

Qingye's electromagnetic cannon can completely snipe the target from a few kilometers away. But this will cause an embarrassing problem.

That is long-range sniping, which requires visual assistance. Otherwise, it is impossible to hit accurately. And Qingye can't do this.

There are telescopes in this world, but telescopes and scopes are completely different. And Qingye used his own arm to perform this move. Even with a scope, it would be useless.

This problem is easy to solve in the ninja world. The Byakugan is one of the most perfect solutions. Imagine a Byakugan ninja who can spot the enemy from several kilometers away.

However, he stood there without moving. He fired a super long-range electromagnetic cannon directly, blowing up the head of the enemy hiding in the tree hole. What a thrilling scene.

But the reality is that Aoba doesn't have the white eyes. Moreover, the Hyuga clan is extremely closed. If Aoba has no friendship with the other party and rashly goes to the door and says that he wants to take a Hyuga clan member as a disciple, the other party will not accept it.

And from another perspective, Lightning Release Flash is a very dangerous ninjutsu. If this technique falls into the hands of someone with bad intentions, Qingye will not be able to sleep well at night. He can't teach it to others casually.

Sasuke is the lucky child of this world, so Aoba can make an exception. If others want to learn, Aoba will not teach them casually.

"Alright Sasuke, that's enough training for today."

"But Aoba-sensei. I can still..." Sasuke wanted to continue training, but Aoba interrupted him.

"Sasuke, have you forgotten what I said? More haste, less speed. This is not a technique that can be completed simply by working hard. During the training process, you need to constantly find your shortcomings and constantly adjust yourself.

Carefully feel every subtle change in the chakra. You can't do this when your body is extremely tired. So, listen to me now and go home to rest. We'll continue tomorrow."

"Okay." Sasuke was a little disappointed. But he was in a good mood at the moment. As long as Uchiha Itachi didn't provoke him from time to time, he was actually still a very good child.

In the original story, both Uchiha Itachi and Sasuke were too obsessed with the Sharingan. Itachi would occasionally pull Sasuke into the Tsukuyomi space, letting him watch the scenes of the night of genocide for three days and three nights. It was really a bit outrageous.

In fact, in Qingye's opinion, opening the Sharingan too early is not a good thing. It is stronger, but in addition to that, one is that this Uchiha's emotions are more extreme. Another is that it is extremely burdensome to the body.

Qingye even felt that Uchiha Itachi's poor health was related to the fact that he opened the Mangekyō too early.

Without the Eternal Mangekyo or Hashirama's cells, the side effects of the Mangekyo are really a bit too great.
