Ninja school teacher, I can become stronger by teaching...

"Don't move, let me test my ability first."

Kakashi said as he regained control of his body.

"Why should you play first?"

Obito was unhappy. This was their common body, why couldn't he try it first?

Kakashi was too lazy to argue with Obito, so he simply let Obito take control of the body first.

After a period of testing, Obito discovered that this body was indeed not weak.

Although it is impossible to launch a 70-meter Susanoo, the output limit is not low.

If a real fight breaks out, it's hard to say who will win or lose.

"You guys can just take the Potara earrings. You can practice combining them when you have time."

After the test, Mu Yue gave the Potala earrings to her disciple.

"Kakashi, you should focus on the Unlimited Technique for the near future. Master it first."

Then Mu Yue began to guide his disciples in their practice.

In fact, Mu Yue had already started teaching Kakashi to be shameless before his identity was exposed.

Firstly, there were very few people who had seen Sosuke use his unbridled power, and Konoha had kept the information about that battle top secret, so Kakashi had no idea that Sosuke had this ability.

Secondly, there is a huge difference between the initial stage of cultivation without lower limits and the performance of Mu Yue who has already reached the mastery level without lower limits.

Now Kakashi is only a few points away from the entry level of no lower limit.

"Ah."

Kakashi nodded and then asked Mu Yue a question.

"Teacher Muyue, can we use the Potara earrings to practice?"

When they just merged, Kakashi had an inexplicable feeling that practicing without limits would be easier for him.

Kakashi told Mu Yue all of his feelings.

"Of course you can, but you have to control the frequency. Don't do it too often, especially when fusing the soul and body at the same time."

Mu Yue thought for a moment and replied.

He believes that there should not be too many fusions, especially of souls.

It would be bad if two people get along with each other and their souls gradually become like each other.

"I'll pay attention."

Kakashi nodded in thanks.

A week later, Kakashi successfully mastered No Bottom Line.

He would fuse with Obito every day, and each of them would practice for thirty minutes during the fusion.

Shisui will also merge with Yamato to practice the changes in the nature of yang chakra and yang breathing.

Yamato's strength is far from his, but Yamato has Hashirama's cells in his body, which is a good thing for cultivating yang attributes.

About three months later, Mu Yue settled the disciple promotion rewards after a long absence.

[Disciples Uchiha Shisui, Uchiha Obito, Might Guy, Hatake Kakashi, Nagato, and Yamato have diligently trained under your guidance. Their overall strength has greatly improved, and they have been awarded the Sage Body.]

Looking at the message that suddenly popped up, Mu Yue couldn't help but reveal an expression of surprise on her face.

He had almost forgotten when the last time the disciple promotion rewards were calculated. He thought it was a benefit for the novice period and would disappear when the disciple reached a certain level of strength. It turned out that they were holding back a big one for him.

The moment Mu Yue obtained the immortal body, the aura surged, the chakra in his body increased rapidly, and Mu Yue's white eyes and black eyes automatically opened, replacing Mu Yue's original blue eyes.

“Did you get complementation?”

Looking at the chakra that was surging on the panel, even Mu Yue's expression showed a hint of emotion.

When Mu Yue's breathing stabilized, the numbers on the panel stopped jumping.

[Name: Hanyu Muyue]

【Chakra: 11.2 million】

His chakra soared directly by more than 6 million, which was much more than the chakra increased by the last time the Byakugan evolved.

Of course, this does not mean that the immortal body is more powerful than the evolved Byakugan.

Mu Yue believes that there are two reasons for this result.

First, chakra is one of the specialties of the immortal body.

Second, his eyes and the immortal body form a spiritual and vital complement.

If Mu Yue didn't have the evolved Byakugan, the increase in chakra would still be a lot, but it shouldn't have skyrocketed to over six million.

"Sure enough, in the Naruto world, if you want more chakra, you need bloodline."

Mu Yue couldn't help but sigh in her heart.

Compared to the chakra that the Sage Body and Sage Eyes brought him, all other rewards combined were just a drop in the bucket.

"The Yang attribute's changes have caught up. We need to find a way to raise these changes to the perfect level."

Mu Yue thought as she looked at the panel.

【技能：土属性查克拉性质变化（精通级：12600/15000）、阴属性查克拉性质变化（精通级：12100）、风属性查克拉性质变化（10600）、阳属性查克拉性质变化（精通级：9000）】

Mu Yue's original proficiency in the earth-attribute chakra nature change was not high, but after benefiting from the perfect-level wood escape, his proficiency increased all the way and surpassed other nature changes.

Now, even Mu Yue's lowest proficiency in the Yang attribute chakra property change has reached nine thousand points.

And because of the immortal body, Mu Yue's cultivation of yang-attribute chakra will surely go smoothly.

So he thought that he could now charge towards the perfection level of all chakra property changes.

Mu Yue had a hunch that if all seven chakra attributes reached the perfect level, his upper limit of strength would be greatly improved, and might even undergo a qualitative change.

Mu Yue fell into thought.

At this level of proficiency, it would take a very long time to advance through ordinary practice.

It's easy to deal with Yin and Yang that have training bonuses, but the wind attribute is difficult to deal with.

"Hold a large-scale lecture event and see what the lecture rewards are like."

Mu Yue decided to start a large-scale lecture to achieve perfect-level skills.

Because of the generous rewards of the advanced courses, he would occasionally write some lesson plans and wait for the right time to use them.

"I don't know if there's a higher rating than the advanced class."

Things are different now. Mu Yue is now the leader of the Ninja Alliance. His influence is far greater than that of the Ninja Master. He can easily call upon tens of thousands of ninjas, including even outstanding students like Jinchūriki.

If this still fails to trigger a rating above advanced, then Mu Yue can only assume that the highest rating for the course is advanced.

Even tens of thousands of ninjas and several Jinchūriki can't do it. Does that mean he has to capture a dozen Otsutsuki to come and attend his classes?

If he had this ability, he wouldn't need to attend classes.

I believe that Otsutsuki would not provoke a strong man like him just for a planet.

Mu Yue did what he said and quickly asked his subordinates to spread the news to warm up for his lecture.

If the teaching effect is not satisfactory, he will activate the shadow clone to practice Dafa.

Just go slow, he can't guarantee the rest of the time, but there will be no Otsutsuki coming to the ninja world in the next ten years.

Uchiha Madara is dead and only Black Zetsu is left, who can't cause any trouble.

Mu Yue has enough time to develop, so there is no need to rush.

After releasing the news, Mu Yue personally took action and used Wood Release to build a conference hall that could accommodate tens of thousands of people, specifically for lectures.

With the help of the Ninja Alliance, the news of Mu Yue's lecture spread throughout the Ninja World in less than a day.

In fact, the information technology in the ninja world is not particularly bad. Many of the things that Mu Yue had in his previous life are also available in the ninja world, but they are relatively backward.

The only reason they seem backward is that the ninjas have been at war for years and there is no soil for development.

After the Ninja Alliance was formed and the Ninja World temporarily achieved peace, information technology developed rapidly with each passing day.

"Master Ninja is finally giving another lecture, I have to attend!"

"Since our leader is willing to take time out of his busy schedule to give a lecture, I have to go!"

The ninja world became restless due to this news.

Needless to say, those ninjas who had listened to Mu Yue's lectures before were willing to listen to Mu Yue's lectures even if they had to pay.

"If the Fourth Hokage is giving a lecture, then we must support him."

"It would be a big loss if you don't attend Teacher Mu Yue's class."

Among them, the ninjas of Konoha showed great enthusiasm.

Other ninja villages had at most heard rumors about Mu Yue's teaching ability, but many Konoha ninjas had actually taken Mu Yue's classes.

This is also the reason why when Sosuke was at the peak of his fame, many Konoha ninjas still did not take his title of ninja master seriously.

In their hearts, Mu Yue's teaching ability has reached the super-god level of turning decay into magic. No one can match him, let alone surpass him.

In addition to announcing the lecture information, Mu Yue also sent separate invitations to the Jinchūriki and some powerful people in order to improve the quality of students in the class.

All the ninjas invited by Mu Yue readily agreed and said they would definitely be there.

If it was before the emergence of the Ninja Alliance, perhaps some people would refuse, but now Mu Yue's strength and identity have undergone a qualitative change. Even the Five Kage are not considered to be on the same level as Mu Yue.

Such a Mu Yue is certainly qualified and capable of teaching all the ninjas in the ninja world.

When Mu Yue announced the specific lecture date, all the ninjas in the ninja world started to move.

The strongest person in the world is still the strongest person in the gap.

If a ninja like this is willing to give a free lecture, then you have to go and listen even if you have to risk running into your mortal enemy.

After all, teaching ability is also one of Mu Yue’s well-known characteristics.

……

The day before the lecture began, ninjas from various ninja villages could be seen everywhere in Liudao Castle.

There are not only five major ninja villages, but also ninjas from various ordinary ninja villages.

Some ordinary ninja villages are led by their leaders, who bring most of the ninjas in the village to attend classes.

If it were in the past, such a thing would naturally not happen because it would be easy for hostile forces to steal the house.

But now the Ninja Alliance does not allow large-scale conflicts to break out among ninja forces. Those who dare to start a war must consider whether they can withstand the iron fist of the Ninja Alliance.

Those ninja village leaders who personally went to Six Paths Castle, in addition to being curious about the lectures of the strongest, actually also had the idea of ​​joining the Ninja Alliance.

The Ninja Alliance not only does not allow war, but also mobilizes a large number of ninjas to crack down on illegal ninjas throughout the ninja world.

Many evil wandering ninjas and underground ninja organizations were eliminated, which greatly improved the public security of the entire ninja world.

This has greatly compressed the living space of many small ninja villages.

Since there was no war, the number of escort commissions decreased significantly, and the commission income dropped sharply.

In this case, joining the Ninja Alliance is a good choice.

"It's the Fourth Mizukage, Yagura Karutagi!"

"That's the Godaime Kazekage Chiyo!"

There was a ninja standing on the street, and with a casual glance, he found many big guys that he would hardly see in his entire life under normal circumstances.

At Mu Yue's invitation, all five current Kage arrived at Liudao City.

At the same time, Mu Yue temporarily released the imprisoned shadows and allowed them to move freely in Liudao City.

These shadows are quite capable and can serve as excellent students, improving the quality of Mu Yue’s courses.

Since they have nothing to do anyway, they might as well attend the class and make some contribution to Mu Yue's strength improvement.

As for the Jinchūriki, except for the One-Tail Jinchūriki Gaara and the Seven-Tail Jinchūriki Kaede who were too young to come, the remaining seven Jinchūriki were all present.

Mu Yue could understand this. Gaara had only been born for less than two years. Even if he was brought here by force, he wouldn't understand and it wouldn't be of any use to him.

Mu Yue's system is very strict in terms of lecture evaluation. Not only does Mu Yue have to teach well, but students also have to study hard and learn something, so that they will receive good rewards in the end.
