(After being reminded by a book friend, the gossip seal in the previous chapter was changed to the four-elephant seal, but it did not affect the reading.) ）

"What the hell is your head?"

Tsunade stared at Hachiki Rinya strangely, his eyes wandering.

The more she thought about it, the more she felt that what Qi Mu Lin said was feasible.

The theory is feasible.

Although it will be much more complicated to operate, it will even extend the development cycle of this trick.

But with the Four Elephant Seals and other tailed beast sealing techniques in front of them, this idea is obviously correct.

It doesn't make sense that a huge chakra like a tailed beast can be used, but a little chakra of humans themselves can't be used, right?

Qi Mu Lin also cried and laughed: "As you can see, it's like this." ”

The question about the medical ninja training system that I mentioned to Tsunade earlier is based on the knowledge of the previous life.

But this time, it was a pure flash of inspiration.

It can even be said that when he watched anime, he didn't realize this problem.

It wasn't until he got to know the structure of the Yin Seal technique that he realized a problem.

A particularly important question.

As we all know, the so-called chakra amount does not refer to how many chakras are stored in the body.

In fact, the amount of chakra that ninjas often talk about actually refers to the total amount of chakra that a ninja can refine without being replenished or resting.

In simple terms, it can even be understood as the limit of physical and mental energy.

The quality of these two items directly affects the total amount of chakra.

But the embarrassing thing is that these two qualities are very confusing, and there is no formal way to improve.

At least for humans, it's a shackle that is hard to break.

But Tsunade is taking a different path.

She wanted to store the chakra and release it when she needed it.

At that time, the amount of chakra released will be comparable to that of a tailed beast.

Of course, this idea is probably not the first one that comes to Tsunade's mind.

Tsunade, however, was the first to tackle this problem.

She had successfully developed a way to store chakras, and now she was just the finishing touches!

At this time, Tsunade suddenly asked, "By the way, do you have any other ideas?" ”

This time, Tsunade also became aware of the idea of Rinya Hagi.

Inspiration is sometimes so important that a flash of inspiration can outweigh a decade of hard work.

Qi Mu Lin also thought about it and said, "Once the physical energy and spiritual energy are exhausted, people will die, am I right to say so?" ”

"That's right."

Tsunade nodded, a little strange why Qimu Lin suddenly got involved in this issue.

Isn't it the development of her trick that is being discussed?

But Qimu Pro is indeed not wrong.

It's okay to run out of chakra, but you must not refine chakra by squeezing your body.

This is something that everyone who embarks on the path of ninja will be told.

Because the refining method of chakra is very dangerous, as long as it is used all the time, it will squeeze the last trace of energy from the stem cells.

At that time, the cells will die in large numbers, and the person will die.

Qi Mu Lin also continued to ask: "If physical energy and mental energy are replenished, can people live longer?" ”

"This ...... Unlikely, right? Tsunade hesitated.

"Why can't it be? The reason why people die, in the final analysis, is actually caused by the aging of cells, if you can replenish enough energy for the cells, the body will not age, that doesn't mean that you don't die? ”

Tsunade rolled his eyes and said, "Your idea is good, but the aging of human cells cannot be stopped. ”

"Okay, then I don't have a doubt." Qimu Pro also spread his hands.

This was so angry that Tsunade almost vomited blood.

She wanted more ideas from Rinya Hagi!

And it turns out to be a Q&A?

In fact, Qimu Lin is also very helpless.

He just suddenly thought that the anti-aging effect brought by the Yin Seal was actually equivalent to maintaining the vitality of cells, so that the body would not become old.

So he suddenly thought, if the cells remain alive, will it be able to achieve the effect of prolonging life?

Besides, he doesn't even understand why cells age, so how can he give any opinion?

Also, in the original book, after Tsunade lifts the Yin Seal and exhausts the chakra, the body will age rapidly.

From this point of view, the Yin Seal does not really keep the body's cells in peak condition.

Of course, it's too early to tell.

I'm afraid that even Tsunade, the developer of the Yin Seal, didn't realize that this technique also had the effect of rejuvenation.

Facing Tsunade's cannibalistic gaze, Qimu Lin also said helplessly:

"What do you think of inspiration? Chinese cabbage? ”

"Hmm." Tsunade also understands that there is no such thing as a flash of inspiration, "Then if you have any ideas in the future, remember to come to me for details." ”

"No, non-existent."

Hagi Lin also decisively refused, he felt that Tsunade had used himself as a creative ATM.

To be reasonable, he doesn't feel that he really feels that he is really comparable to those geniuses in the ninja world.

The only thing that is commendable is nothing more than the insight of the previous life.

Compared to the real geniuses of Senju and Orochimaru, he felt that he couldn't catch up.

At this time, Tsunade asked, "Since you think my trick is powerful, do you want to learn it?" ”

"This ...... Naturally, I want to learn. ”

Qi Mu Lin also hesitated for a moment, but finally affirmed.

Two months ago, he came into contact with Tsunade, and it was not a note that he was playing the Yin Seal.

But now he found that it was enough to directly use the system to improve, so that heart fell silent again.

However, since reading Tsunade's notes, he suddenly discovered that the Yin Seal is very similar to "Cultivating Immortals"!

So, he became eager to try again.

Always relying on the system to become stronger, so that he has a feeling of being subject to the system.

Now, there's another avenue in front of you, and there's no reason not to give it a try!

Besides, this is a "cultivation of immortals", and he also has a dream of immortals.

"If you want to learn this ninjutsu, you have to start with strange mechanics." Tsunade.

Qimu Lin also suddenly showed a bitter face.

Strange power pays attention to Chakra's explosiveness and control, and these two points happen to be his shortcomings.

Just as Qimu Lin wanted to ask if there was any shortcut, there was a knock on the door.

Knock knock.

"Who?" Tsunade screamed.

"Tsunade-sensei, it's me." Mikoto Uchiha's voice came.

"What's the matter?" Tsunade asked.

"Ah, it's not a big deal, I just want to ask, do you want to continue today's cultivation?"

Hearing this, Tsunade was slightly stunned.

She looked at the sky and saw that the sun was already shining.

It turned out that before I knew it, an hour had passed.

"Wait a minute, I'll change my clothes and come." Tsunade replied.

She is still wearing her pajamas.

Looking at Kiki Rinya, who was drinking tea to moisten his throat, Tsunade explained: "Take this note, you take it back and continue to study it." ”

With that, Tsunade walked to the room.

Until she walked into the room, on the eve of closing the door, she said suspiciously: "Don't peek, or I'll kill you!" ”

Qimu Lin, who had just taken a sip of tea, also spewed out suddenly.

He laughed and said, "Who are you and me?" ”

He suspected that it was Jiraiya's pot.

Tsunade must have been scared by Jiraiya, so he was suspicious.

But he's a decent man!

How could you go back and peep?

"Trigger D-Class Mission: A Glimpse of Truth in the Hole"

『Quest content: Voyeur Tsunade......

『Reward: Crystal)

“……”

This system is definitely poisonous!

……

When Hachiki Rin also walked out with Tsunade, Uchiha Mikoto was stunned for a moment.

And a change of clothes or something.

"Senior, you are ......"

"I encountered some problems in my cultivation, so I came to Tsunade early to solve my doubts." Qi Mu Lin also explained.

Ninjutsu, especially advanced ninjutsu, is very secretive.

Qimu Lin didn't get Tsunade's permission, so naturally he wouldn't reveal the Yin Seal.

He still has this sense of confidentiality.

"So? The seniors are really working hard, and I have to work harder. Uchiha Mikoto laughed.

"Where's Ukyo?" Tsunade asked.

"Ukyo-san, he doesn't seem to be in the room, and he doesn't know where he went." Mikoto Uchiha worried.

"He must have escaped, this guy wanted to play after he came to the national capital." Qimu Lin couldn't cry or laugh.

Although the time they have been together for a short time is still short, Hagi Lin also feels that he has seen through Ukyo.

That guy does things out of interest, so to speak, and does whatever he wants.

Fortunately, his nature is not bad, and he has never thought about doing anything bad.

"This kid is too lazy."

Tsunade was also so angry that his teeth itched.

Since she has been the instructor of the ninth class, Tsunade has no intention of getting by, even if it is Uchiha Mikoto, she is also responsible for guidance, and there is no ambiguity.

However, since you are a human being, you will inevitably bring personal feelings to your work.

Therefore, compared to Uchiha Mikoto, Tsunade prefers Ukyo, who is cuter than a girl.

So, what was taught to Ukyo was also the medical ninjutsu that he was best at.

But Ukyo actually ran away?

"Why don't we go get him back?" Qimu Lin also said helplessly.

In fact, he is also worried that Youkyo will make trouble everywhere and end up getting into trouble.

Especially when this "temporary Konoha Mission" is under suspicion.

Tsunade snorted and said, "No need, you go to cultivate first, and I'll go and get him back in person." ”

Qimu Lin couldn't help but wonder: If Youjing is caught by Tsunade, I'm afraid it will be a good meal.

However, since Tsunade spoke, Hachiki Rin and Uchiha Mikoto naturally had no opinion.

After Tsunade left, the two traveled together and headed out of the city.

It didn't take long for him to arrive at the place where he cultivated yesterday.

There was no nonsense, and the two immediately began to cultivate.

Qimu Lin also took out his notes, directly skimmed over the content that he couldn't use for the time being, and directly found the part about strange powers.

The so-called strange power is actually to concentrate the chakra in one part of the body, and the effect of breaking the sky and the earth will burst.

Among them, the control of the chakra played a crucial role.

Therefore, to learn strange forces, we have to start with Chakra's control mechanics.

According to the notes, the so-called control is actually inseparable from a person's spirit.

To understand it simply, it is nothing more than to summarize it in four words.

Concentrate!

Feel the flow of the refined chakras carefully, and then control them.

Yes, it's that simple.

However, it is by no means simple.

That's right, when a ninja meditates, it is indeed easy to concentrate, and after training, the mind is free of distractions is also something that can be done in a short period of time.

However, it must be understood that when fighting, there is not so much time to hold your breath and concentrate.

Fortunately, Tsunade's notes have a very detailed explanation of this, and it is described in four words.

Skill comes from practice!

"I see, the so-called careful control is just the foundation, and when it is really used, it depends on the instinct that has been tempered thousands of times!"

Qi Mu Lin also looked at the description of the strange power on the note, and suddenly realized.

That's right.

Even a person with exceptional talent can hardly be able to concentrate and be distracted in battle.

Moreover, if the mind is focused on controlling the chakra, it means that it is difficult to notice other problems, and it may even reveal flaws for the enemy to take advantage of.

This is clearly not worth the cost.

"But in the end, the requirements for control are still very high, everything is difficult at the beginning, even if you want to achieve practice makes perfect, the first condition is to concentrate the chakra first, if you can't even concentrate, then there is no explosion, let alone form an instinct......"

Qimu Lin also smiled bitterly, this is his shortcoming.

However, things have to be tried.

It's not his style to give up without trying.

"Focus, it's easy to say......"

Qimu Lin also closed his eyes and held his breath to concentrate.

The sound of water, wind, insects and birds flowed in my ears.

Qimu Lin also began to regulate his breathing and thoughts, and restrain his distracting thoughts.

In the end, Hachiki Lin was also attracted by the gasp of Uchiha Mikoto.

Pit daddy, this is!

As soon as you close your eyes, you can have no distractions?!

Isn't this a must-have skill for a traverser?!

No way, Qimu Lin had to refine a little chakra first, and try to control it first.

"Huh?"

A surprised voice sounded, and the chakra, which had just been controlled, immediately dissipated.

Qimu Lin also opened his eyes with a strange expression.

"Chakra, is it so easy to control?"

He found that he could easily control a wisp of chakra.

And this is something that could not have been done before.

Now that it's suddenly done, it's not normal no matter how you look at it.

Qimu Lin, who did not believe in evil, also concentrated his mind again, controlled the chakra in his body, and slowly concentrated it on his fingertips.

When I opened my eyes, I saw a blue color spraying out from my fingertips.

It's light, it's thin, but it's there.

Qimu Lin was also stunned for a moment.

You must know that under normal circumstances, the chakra that is not controlled will disperse to all parts of the body and dissipate.

If the amount is not controlled, the whole person will be wrapped in chakra.

It's domineering, but it's also wasteful.

But the phenomenon of dissipating from the fingertips like the one now is a proof that the chakra is being guided in one place.

Qimu Lin also touched his head, his hair was still there.

"I'm not bald, why did I get stronger?" [.]
