I am not a knight, reborn as an old sword

After figuring out the key points, Liuyun comforted Tsunade and others, saying that he would send someone to investigate the matter, and then returned to the ninja school.

Tsunade and the three consultants had no choice, because there was no clue about the matter, and it would take more than a day or two to investigate it, and it was very likely that it would never be found. After all, the Book of Seals was stolen silently, which was the first time in Konoha's history. If the person who stole the Book of Seals destroyed it, I'm afraid that even if I investigated it for another hundred years, there might not be any results.

Fortunately, Liuyun knew all the contents of the Book of Seals, and he could write another Book of Seals if he wanted.

At least the inheritance of Konoha's forbidden techniques and secrets would not be lost.

As for what the person who stole the Book of Seals would do, it was not something they could control, and they could only deal with it when the time came.

As a time traveler, Liuyun naturally knew the secrets of the ninja world. As long as the tailed beasts did not get into trouble, the final boss Kaguya would not appear, and Liuyun would always be able to occupy the dominant position.

After all, he is now the God of Ninjas, and is recognized as the most powerful being in the Ninja world.

When it comes to combat power, no one knows how strong he is better than Liuyun.

Even if Hashirama Senju is reborn, he can't be his opponent.

So, Liuyun is not weak at all.

However, he secretly sent people out to find the whereabouts of the Sealed Book, and also contacted Esdeath to let her pay attention to this matter.

Next, Liuyun trained students in the genius class while creating and researching some ninjutsu, secret techniques and the like.

In addition, he also needs to learn the sealing technique.

For this reason, he also sent people to find the ancestral hall of the Uzumaki clan, and found some information about the sealing technique from it for research.

Especially the death masks, each of which represents a death god of the Shikigami Fujin.

These death masks are all sealing props made by the ancestors.

And each death god is actually the soul of the ancestors of the Uzumaki clan.

The more Liuyun studied these sealing techniques, the more he found them to be profound.

He even discovered that the sealing technique involved the soul, the mystery of time and space.

Time passed unknowingly, and in a blink of an eye, three years had passed.

Under the guidance of Liuyun, the students in the genius class had made great progress.

Among them, Aburame Tone was favored by Liuyun for her special abilities and became Liuyun's bodyguard.

Hyuga Neji, Xiao Li, Tiantian and others had graduated a year early.

And this day was the beginning of another graduation exam for the Ninja School.

Under Liuyun's evil taste, he refused to let those under the age of twelve in the genius class graduate early, and let them concentrate on graduating with other ordinary students this year.

He even specially transferred Naruto back to take this graduation exam.

Although the plot has deviated too much from the original, under Liuyun's forced evil taste intervention, the twelve little strong men in the original still took the graduation exam together.

The graduation exam project is very simple, which is the use of the three body techniques.

After Liuyun's special training, the students in the genius class all have at least the strength of Chunin.

Among them, Uchiha Sasuke, who is more talented, has even developed his Sharingan to the state of three magatama, and his strength has reached the level of a special Jonin.

Even Hinata has the strength of an elite Chunin.

However, everyone is still a student and has not yet become a ninja of Konoha, so even though they are very strong, they can only participate in the graduation examination according to the process.

After passing the examination, they will be assigned to a Jonin instructor to carry out tasks like everyone else.

"I really don't know why Principal Liuyun wants us to take this boring graduation test. With his power, he can just give us a ninja forehead protector!"At the test site, a student from the genius class complained as he watched other ordinary students take the simplest three-body test one by one.

This test was a unified test for all students who reached the age of twelve. If they passed, they would become Genin, and if they failed, they would continue to repeat the grade.

"Principal Liuyun certainly has his own intentions, we just need to listen to him, why are you nagging!" Another student from the genius class shouted at him.

""Wow! It's Sasuke! It's Sasuke from the genius class!" At this time, a scream rang out.

Sakura from the ordinary class looked at Sasuke with amorous feelings, and screamed at Sasuke with loving eyes.

Sasuke glanced at Sakura coldly, thinking that she was really noisy, and quickly performed a transformation technique, successfully passed the test, then took the forehead protector and turned away.

At this time, in the yard of Liuyun's house.

Liuyun was sitting opposite Kakashi and drinking tea.

On the coffee table, there was a crystal ball, and the scene of the test in the class was reflected in the crystal ball.

This crystal ball was specially asked by Liuyun from Sarutobi Hiruzen. When he had nothing to do, he would do some things to spy on other people's lives.

Although it is incredible that such a thing happened to a ninja god like Liuyun, Liuyun had no choice, because this world lacks entertainment. In addition to studying ninjutsu, he always has to have some amateur program fun. It is also fun to spy on others with a crystal ball.

No wonder Sarutobi Hiruzen would research this ninjutsu.

"Liuyun, you are really giving me a difficult problem. Sasuke has already learned Chidori and his Sharingan has reached three magatama. I don’t have anything to teach him."Kakashi protested to Liuyun,"And with his current strength, I am afraid that even I may not be able to suppress him, right?"

Because Liuyun wanted Kakashi to become Sasuke's and their jonin mentor.

But Kakashi knew that after Sasuke opened the three magatama Sharingan, his strength should be comparable to that of an ordinary jonin. Although Kakashi is an elite jonin and has now opened the Kamui Mangekyō, it is still very stressful to lead a student like Sasuke.

"Oh, by the way, I plan to let you take care of Naruto for the time being." Liuyun said again.

Kakashi immediately broke out in a cold sweat:"Liuyun, you think too highly of me. Sasuke is fine, but why do you let me take care of Naruto? Isn't he a member of your [Beast] organization? Are you so confident that he can follow me on missions?"
