The years have flown by, and in the blink of an eye, a month has passed in a hurry.

And Naruto also stayed in the sealing class for a month.

This surprised Tsunade, originally she thought that Naruto would be able to return triumphantly from the sealing class in one day, and then learn the Yin Seal the next day, understand the art of Baihao on the third day, and become a teacher on the fourth day.

Tsunade knew it was, but hadn't Naruto been all along?

Could it be that the steps in the past were too big, so it got the egg?

"Mute, Naruto hasn't been here in a while, has he?"

The afternoon sun shone in the Hokage's office, and it was so warm that you couldn't help but want to sigh.

So Tsunade sighed and stretched lazily.

The deep V open-cut blouse pulls out a striking curve in this lazy waist, showing the forbidden temptation.

Shizune was stunned when asked, and his expression suddenly changed for a moment before he remembered that there was such a person as Naruto.

Tsk, it's been a long time since I've seen that guy.

He replied, "Calculate the time...... I should have beaten that guy to join the sealing class...... I don't think I've seen it before......"

Tsunade's chair turned, the sunlight entered his eyes, and he couldn't help but sneeze and muttered, "Oops, maybe that guy is also thinking about me as a master, huh...... Then should I go to the sealing class and see what that little guy is up to? ”

Silent and speechless, my heart clearly said that you want to meet that guy......

Without Naruto's-stirring stick coming out to stir things up, how comfortable these days were, no thrilling flesh jumping, no thunderstorming, and no one grabbed the guinea pig with her.

Thinking of the guinea porpoise, the silence is very satisfied, and the guinea porpoise has been a lot more obedient recently.

So he incensed it on the forehead of the guinea porpoise.

The guinea pig hummed and chirped very much, and felt that pigs should be like this.

But well...... In retrospect, it seems like I've been bored lately......

This idea is so dangerous, the guinea pig shook his head again and again, he didn't think about the guy who lost his conscience.

So...... What is Naruto doing?

In a separate room in the Sealing Class, Naruto sat in a small room of more than ten square meters, with all sorts of things piled up next to him.

Open, rolled scrolls were scattered all over the floor, and there were many prosthetic parts, wooden shells, alloy shells, and so on.

Some parts are also printed with strange symbols, those are the marks left by the sealing technique, which is also the subject of Naruto's current research, and the method of sealing the chakra is integrated into the prosthetic leg, so as to reduce the loss of chakra and increase the volume of the prosthetic limb that can be controlled.

Prior to this, after coming to the Sealing Class, Naruto spent a day scanning all the books that the Sealing Class could open to him, and that night Naruto began to study the Four Elephant Seals on the Forbidden Scroll with these huge knowledge points.

Because Naruto found that the Four Elephant Sealing Technique was easier than the Filthy Earth Reincarnation, of course, learning knowledge had to start with the simple.

So with the help of the knowledge system formed by the memory, Naruto understood quickly.

For the knowledge points that you don't understand, they are also separated, and they ask different people for advice.

In two days, Naruto thoroughly understood the theoretical knowledge of the Four Elephant Seals, and on the third day, there were some problems in practice, and he summed up the problems and asked someone for advice again, and on the fourth day, he finally learned the Four Elephants Seal.

On the fifth day, Naruto began to study Filthy Earth Reincarnation.

After studying the Filthy Earth Reincarnation, Naruto discovered that the knowledge points contained in the Filthy Earth Tensei were really ...... It's hard.

The most important thing is that there are many knowledge points that cannot be asked, such as the principle of the reincarnation circle to gather souls, and the corpse raising involved in preserving the corpse coffin of the reincarnated person of the filthy soil after the second step is successfully performed.

So Naruto could only pick out the knowledge points involved in the taboo, and first get the other knowledge points, the contract used in the Filthy Earth Reincarnation Circle, and the psychic used after reincarnation.

Contract and psychic, these two can be seen as one, equivalent to the full version of spiritism.

It's not a spell, just a handprint, it's all the knowledge points from how to make a contract scroll to sign a series, the fifth day begins to learn theoretical knowledge, the sixth day practice summary, the seventh day of casting again fails to summarize and find someone to answer questions, and the eighth day finally succeeds.

On the night of the ninth day, he stole the forbidden scroll that was not open to him, and the theft failed, and all the scrolls involving secrets had various encryption methods, which could not be done at Naruto's current level.

On the tenth day, Naruto borrowed it as a disciple of Tsunade instead of Tsunade, and there is a high probability that this trick will be discovered, but Naruto has no other way, in short, he will write it down in his head first.

When the time comes, if Tsunade asks, then he will pretend to be stupid or hob.

To Naruto's surprise, the Forbidden Book Administrator didn't suspect him, and asked him if Tsunade hadn't borrowed it before?

The moment he heard this, Naruto understood, it must be Tsunade who was also studying Filthy Earth Reincarnation.

Then Naruto successfully borrowed it on the grounds that he wanted to take another look, and what was even more amazing was that he didn't even need to write the file, and only said that he would return it within seven days.

Naruto's eyes were useless for seven days, and after five minutes of scanning, he returned the effort he had made to the toilet, only saying that he had misremembered and that Tsunade was going to borrow another book.

The administrator just gave him a blank look, and it couldn't have been smoother.

The knowledge points were successfully obtained, but because he couldn't find someone to consult, Naruto's progress slowed down, and it wasn't until the fifteenth day, after a large number of experiments, that he finally figured out the knowledge points about the gathering of souls, and then on the twentieth day, the corpse coffin of a mouse was successfully made, and the main theoretical knowledge was to let the creature enter a state of hibernation and ease metabolism.

This also applies to people, Naruto even made himself a coffin to sleep in, which feels so good that he freezes the time when the museum opens, and he can sleep until dawn every day.

The only flaw is the safety of the coffin, after all, after entering the state of hibernation, the person inside the coffin has almost zero perception of the outside, so it is relatively dangerous.

It stands to reason that on the twenty-first day, Naruto will be able to leave the sealing class and find Tsunade to enter the next step of study, and then he may really be able to complete the feat of becoming a teacher in thirty days.

But halfway through Naruto, he had other ideas, which he was doing right now, using the technique of sealing on his prosthetics.

The study is 10 days.

Naruto drew on a prosthetic leg, and the ink used in the sealing technique was a special ink, which could record the technique, which in Naruto's understanding was equivalent to the electronic integrated circuits of the previous life, and the various spell seals were electronic components.

Magical very.

However, drawing spell seals is a very mentally demanding job, and people with weak mental power can't do it.

There is no level setting for spiritual power in this world, and it is still determined by the amount of chakra.

Because chakra is a combination of spiritual power and vitality, people with a low amount of chakra must have a shortcoming in their vitality and spiritual power.

When Naruto finished drawing the last spell mark, he finally breathed a sigh of relief, closed his eyes and recuperated for a while, and then began to test after resting.

A prosthetic arm was extremely nimble in Naruto's hand to make various movements, and reacted so quickly that there was almost no delay, and it was clear that he had succeeded!

A sense of accomplishment came over him, and Naruto laughed contentedly.

So what's next?

Start developing a combat prosthetic? Well...... Quite interesting.

Or...... Practice reincarnation in the dirt?

Naruto had only been reincarnated as a rat before, but apparently that wasn't really a reincarnation in the true sense of the word.

Just as Naruto was thinking about what to do next, there was a knock on the door, and Tsunade's voice came in, "Are the people inside still alive?" Alive, a squeak in reply. ”

Naruto in the room blinked and replied, "Squeak! Chirping! ”

Tsunade outside raised his eyebrows and asked the embarrassed members of the Sealing Sect beside him, "Are you sure this room is Naruto and not a rat that has grown into a sperm?" ”

The young man in the sealing class who led the way tugged at the corners of his mouth in embarrassment.

I sighed in my heart, being able to talk to Hokage-sama like this, the people in this room are really the same as the legend, they are the celebrities around the Hokage.

Also, even he, who has been here for three or four years, has not been mixed in a separate room, so he can't compare......
