Inside the canyon.

White thunder intertwined, exploding at the bottom.

Kaede Ye glanced at the arm that had been scorched by the blasted thunder, and shook his arm, and the scorched marks quickly faded and returned to a white and undamaged state.

"It's a bit too condensed...... We have to keep adjusting......"

After Kaede Ye pondered for a while, his palm spread out, and the thunder attribute chakra flowed on his arm again, and was quickly compressed by him, forming a flowing form, attaching and flowing inside and outside the arm, and then letting go of the control.

Cracking sound!!

The thunderbolt exploded again, and his arm was injured again.

"The amount of chakra is still too large, we have to reduce it a little more......"

Kaede's face remained unchanged, and after recovering from the arm injury with a time rewind, he continued to try.

The Thunder Escape Body Forging Secret Technique, which uses thunder to stimulate the flesh cells, is not like a thousand birds, which simply flows on the palm of the hand and the surface of the weapon, but from the inside and outside of the entire arm.

And unlike Chidori, in this process, the thunder-attribute chakra cannot be controlled, because if the control is applied, the thunder-attribute chakra will not form a stimulus to the flesh, but will evolve into an ordinary thunder ninjutsu.

The key point of the Thunder Escape Body Forging Secret Technique is to create a part of the thunder attribute chakra with the most appropriate 'amount', and then let go of the control of this part of the thunder attribute chakra, so that this part of the thunder attribute chakra turns into a thunder arc and naturally explodes inside and outside the body.

This amount needs to be controlled very delicately.

If you are bigger, it is equivalent to using a Thunder Escape Ninjutsu on yourself, which will naturally injure your body, and if it is too small, it will not be able to play the role of forging your body.

Among the information about the Thunder Escape Secret Technique extracted from the three generations of Thunder Shadows, what was missing happened to be the problem of how to control the 'quantity', so this part of Maple Night could only try it by himself.

Of course.

Because he has the ability to turn back time, he can use the most brutal methods to test, and he doesn't need to deduce it carefully little by little.

The second-generation Thunder Shadow who created this ninjutsu back then, increased the amount of thunder attribute chakra little by little, and finally reached the most suitable level, and sorted out a complete set of cultivation methods, which took a long time, and Kaede Night could greatly shorten this time.

Half a day passed.

At the bottom of the canyon.

Kaede Ye looked at the thunder light wrapped around his arm, staring intently until the entangled thunder light gradually faded away, revealing an arm that was not unusual.

"That's it."

Kaede clenched her fists, feeling that her arm was not damaged at all, only a slight tingling, and her toughness seemed to have improved.

Cracking sound!!

After determining the extent of the chakra created, Kaede Ye sat there cross-legged, and the chakra in his body suddenly surged, turning into a thunder-attribute chakra, crackling and swinging, covering the surface of his body in an instant.

Different from the state of the Eight Gates Thunder Escape, the thin layer of thunder light covering the surface of the body was more similar to the form of the third generation of thunder shadows and the fourth generation of thunder shadows, but it looked much weaker.

Zizi!!

The thunder-attribute chakra is constantly intertwined inside and outside Kaede Night's body.

The power of these thunder attributes, under the indulgence and uncontrolled nature of Kaede Night, began to naturally erode every cell of the body, but the degree was just right, and it would not cause damage.

Under this erosion and stimulation, Kaede Ye felt that his whole body was heating up, and every cell seemed to be undergoing the tempering of the thunder attribute chakra.

"It doesn't seem like there's a problem, that's how it should be...... After that, it is a matter of gradual adaptation, gradually increasing the magnitude of the chakra, until the body becomes more and more accustomed to the flow of the thunder chakra......"

After feeling it for a while, Kaede Ye realized that there was nothing wrong, he closed his eyes slightly, and began to practice at five times the speed.

It is worth mentioning.

Just a few days ago, the ability to speed up time has been improved again, and the upper limit has been changed from four times the speed to five times, and the range of time flow rate changes has been increased by a part.

It's just that the ability corresponding to 'Scale III.' is still in the fog, and the fog has only faded a little, and it will be difficult to unlock it in a short time if it doesn't seem to have any special changes.

Zizi!!

If you stand not far away and look at Kaede Night at this time, you can see that Kaede Night is in a strange state, and the position of the whole body seems to have become a fast-forward picture of several times the speed.

The white lightning arcs that kept popping up from the surface of his body, the speed was normal, but the speed of these lightning arcs was not normal, but was born at an extremely fast speed.

The thunder attribute chakra of the quenched body, after turning into a thunder arc, is already an out-of-body ninjutsu, and is no longer controlled by the time flow rate of Kaede Night, but in the state of time acceleration, he will use a higher frequency to create more thunder attribute chakra.

And because his body was in a state of time acceleration, he could still bear the effects of these denser lightning arcs normally, and his cultivation speed was still improved, but this increase was not simply corresponding to the multiplier of time acceleration, but was more complicated and could not be accurately calculated.

Three days later.

Kaede Night completed the most preliminary tempering.

He spent a little time deducing the strength of the next stage of thunder attributes, and then continued to start a new tempering and cultivation.

As time passed, he continued to improve the strength of the thunder attribute, and his physical body became more and more in line with the power of the thunder attribute under the tempering.

In this cultivation process, Feng Ye also confirmed one point, that is, this kind of 'thunder transformation' of the body will indeed help him further open up the Eight Gates of Thunder Escape!

After exercising for half a month, he had clearly noticed that when using the Eight Gates of Thunder Escape, the damage of the Thunder Attribute to the body became much lower, and if he only opened the Fourth Gate, he didn't even need to use Time Rewind to recover, so he could resist that part of the side effects.

"In this way, there is indeed hope to open the eighth gate."

Kaede Ye muttered in her heart.

It was almost impossible for him to open the eighth gate before, because the eight doors of Dunjia belonged to the ninjutsu that was easy first and then difficult, and the more difficult it became from the third gate, the more difficult it became, and when he opened the sixth gate, his physical age would probably grow to about twenty years old, and when he opened the seventh gate, he was afraid that he would have to be over thirty years old.

Although he could use time acceleration to speed up this process, the actual age growth of his body would not change, unless he reversed it by going back in time, but in that case, all the previous cultivation results would be invalidated.

When a ninja reaches the age of 30 or older, the only thing that can be further improved is mental power and combat experience, and the physical body will hardly be improved again.

Forty years old is the peak that can be maintained, and after that, it will gradually start to decline.

If you can't open the eighth gate of the Eight Dunjia by the age of forty, you will probably never be able to open it, because your body has already begun to age.

Not everyone can get to the eighth gate.

Even the seventh and sixth gates are enough to trap the vast majority of ninjas.

But the Thunder Escape Body Forging Secret Technique made Feng Ye see the dawn of opening the eighth gate, because the cultivation of this ninjutsu could make it easier for him to open the next few doors!

Maybe cultivating this secret technique will take him a lot of time, it will take a year or even years to reach a sufficient level, and it will slow down his progress in opening the sixth gate in a short time, but in the future, it will allow him to open the eight doors to the final eighth gate!

Open to the eighth gate.

For him, it means invincibility.

In the state of time acceleration, open to the eighth gate, let alone Madara Uchiha, even if it is a large barrel of wood Kaguya, I'm afraid I won't be able to withstand his blow!
