Staring at the steaming ramen in front of him, Aoyagi was in a daze for a while before he barely picked himself up.

I practiced too much, and I lost my appetite at all, but I couldn't stop eating.

Sighing, Aoyagi rested his slightly trembling hands on the table. His arms were pressed against the table, sticky and awkward, reminding him of the fact that he was sweating profusely.

It's really uncomfortable, so it's better to finish eating and go back to washing.

"Aoyagi," Uncle Yile was a little strange when he saw Aoyagi not moving his chopsticks, "why don't you eat it yet." ”

With a smile, Aoyagi said, "I'm just waiting for it to cool down a bit." ”

"Then you can eat slowly." Although it was a little strange, Uncle Ichiraku turned around with a smile and finished speaking, busy making ramen.

Raising his sour arm and pinching the chopsticks, Aoyagi could only pick up a few noodles at a time and eat slowly.

The noodles are slowly chewed and swallowed in the mouth, and as the food fills in, Aoyagi slowly refreshes himself.

After dinner, Aoyagi immediately returned home.

Soaking in the warm water, Aoyagi squinted his eyes comfortably and let out a long sigh of relief. The muscles that were on the verge of the limit were relaxed in the warmth, and the whole person became lazy.

After receiving Jiraiya's guidance, Aoyagi spent the entire day practicing the body during this time, except for the early morning arcane practice to strengthen the body and spirit, tossing himself to the limit every day, resting properly before continuing, and so on until the sun went down. When you take a bath every day, it's a rare time to rest.

Leaning loosely against the wall of the barrel, Aoyagi gathered the chakra into his hand, and after a moment a long blue translucent sword extended from his palm, holding it for a while, and finally Aoyagi dispersed it.

The stability problem is basically solved, and now the chainsaw can be really developed.

In other words, in order to develop the chainsaw, it was originally to avoid too high requirements for control, so why should you first improve the control of the chakra and enhance the stability?

Originally, Aoyagi wanted to develop a chakra version of the chainsaw directly, but found it difficult to make the chakra flow at the edges. In addition, the thickness of the shaped chainsaw is not low, and in order to maintain stability and maintain the shape, the amount of chakra continuously output is not low, and when you want to make the edges flow, the consumption increases dramatically. After such a continuous output of chakra, Aoyagi's meridians ached faintly.

Development has entered a dilemma for a while, and in this situation, it is either a passive wait for the body's ability to withstand it to improve, or a change of strategy.

Aoyagi was unwilling to wait, recalling and deducing many times in the mental space, and after intermittent attempts in his leisure time in the evening, he probably figured out what the problem was.

After one attempt, Aoyagi discovered that a consistent and steady output of appropriate chakras could improve the stability of chakra mimic weapons. Then the stability of the chakra weapon is likely to be related to the vanished chakra.

And where did these vanished chakras go? It's an escape, right? Why does it escape?

Based on this conjecture, Aoyagi conducted a series of experiments, and finally got the answer, and also understood one of the keys to this ninjutsu.

Although the consumption of chakra is not low, it is not so high. The key is stability, or Aoyagi's restraint on Chakra is not strong enough.

If the chakra can't be restrained, the amount of escape will be large, so in order to maintain the form, Aoyagi must continue to output chakra steadily, otherwise the chakra knife will be shattered due to the escape of the chakra. For example, if you throw a cube of sodium nitrate into the water, it will soon break because the sodium nitrate dissolves in the water, and if you want to maintain your form, you have to keep throwing in sodium nitrate (chakra). Although the chakra does not dissolve as quickly as sodium nitrate, it is not slow.

When the chakra flows, it is like putting a glass rod and stirring it in a beaker, and the chakra will escape faster, and the consumption will naturally increase dramatically.

The rapid chakra escape adds to the difficulty of edge flow. A cloud of air spreading around, and an inflatable balloon, of course, is a balloon that is easy to control.

After figuring out this phenomenon, Aoyagi realized that he had to restrain the chakra from spreading, which would reduce both the consumption of chakra and the difficulty of manipulating.

And the method of restraining the chakra is somewhat similar to the spiral pill, which also requires the creation of a hard membrane-like thing to suppress the chakra.

At this point, Aoyagi finished bathing, went back to the bed in the bedroom, sat down cross-legged, and began to practice.

In accordance with the secret technique of strengthening the body, Aoyagi uses chakra to nourish the cells of the body. However, unlike the precise washing of stem cells that is performed every morning, the specific chakra is only roughly stimulated to the cells of the body.

The original intention was to speed up the strengthening of the body, but after the first attempt, Aoyagi unexpectedly discovered that this method had the effect of helping the body recover.

After adjusting the practice plan and exercising at high intensity for three consecutive days, Aoyagi's body was extremely sore and weak, and he couldn't even pick up a pen. After lying in bed for a long time, Aoyagi temporarily decided to take a day off.

Although it is a rest, you should not slack off, and you can do some light practice.

After Aoyagi underwent a daily secret technique to strengthen his body and spirit, and completed the tempering of his whole body's stem cells and sensory organs, he was bored and couldn't deduce ninjutsu with a pen. Seeing that it was still a long time, he simply practiced the original version of the strengthening secret technique, and used chakra to nourish the cells of the whole body.

Surprisingly, after practicing the secret practice, the body has obviously recovered and is a lot easier.

Aoyagi speculated that it may have been the chakra that stimulated various metabolic activities of the cells, speeding up the body's recovery.

The related mechanism may be that the chakra is injected into the cells to replenish the energy needed for recovery.

Compared with the cells using chemical reactions to obtain energy, which in turn supports metabolic activities and restores the state, the chakra that may be extracted is more efficient as the energy consumed by the cells.

Therefore, although it is also to consume energy and restore the body, it is more efficient to recover with chakra and can recover the body faster. Of course, energy consumption is also faster. After Aoyagi practiced the secret practice that day, he felt hungry an hour or two earlier than usual.

In the past, I only refined a few body cells, and the feeling was not obvious, but now I nourish the whole body, and the consumption is much greater.

Therefore, every night, after practicing the secret, Aoyagi will eat some more supper to replenish his consumption.

After supper, before twelve o'clock, Aoyagi turned off the bedroom light and fell asleep in the dark.

In a bright spiritual space, he began another job: studying ninjutsu......

And so the day ended.
