In the canyon.

Arcs of lightning intertwined and exploded.​​

Yeruashi looked at the hand that was charred by Raiton and clenched his palm, the damage began to quickly disappear, soon the hand returned to perfect condition.

"It was too much...it is necessary to continue the adjustment..."

Yeruashi shook his head, the silvery chakra of the Raiton attribute surged into his palm again, enveloped it and penetrated the flesh, and then ceased to be controlled and turned into aggressive lightning.

Crack!!

There was another explosion and the arm was damaged.

"The concentration is too great..."

Erase remained calm, he restored the hand with the ability to reverse the flow of time and continued attempts.

Tempering the Flesh with Raiton, this is a secret technique that uses Raiton to stimulate the cells of the body, it is not like Chidori, when using which lightning flows over the surface of the palm, instead it penetrates the user's flesh.

And unlike Chidori, in this process, the chakra should not be controlled, because being under control, it will not become an irritant to the user's flesh.

The essence of the Raiton Flesh Tempering Technique is to concentrate the required amount of lightning attribute chakra, and then strip it of control so that it becomes aggressive lightning and naturally engulfs the user's flesh.

If the concentration is too high, it will be like attacking your own body Raitonjutsu, which of course will lead to the destruction of the flesh, and if the concentration is too low, the lightning will not be a powerful enough stimulus for the cells.

In the information extracted from the corpse of the Third Raikage, the fragment that described the control of chakra concentration was most damaged, so Yeruashi can only try to figure it out on his own.

Sure.

With the ability to reverse the flow of time, he can roughly test everything on himself, there is no need to be careful and double-check each conclusion.

In the past, when creating this technique, the Second Raikage was extremely careful to increase the concentration of Raiton, until gradually he achieved the d.e.s.i.r.ed result. It took quite a long time, but Yeruashi can act much more aggressively and greatly reduce the time.

Half a day later.

At the bottom of the canyon.

Yeruashi stared intently at the arcs of lightning that pierced his palm, after a while they dissipated without causing any visible damage.

"It fits."

Crack!!

Having determined the necessary degree of concentration of the chakra, Yeruashi sat on his knees and concentrated, in the next moment his chakra flashed, turning into a Rayton, arcs of lightning enveloped the entire body.

It wasn't like a Thunder Gate, where the body is wrapped in a thin layer of Raiton when opened, but rather a weakened version of the Lightning Chakra Mode of the Third and Fourth Raikage.

Crack!!

Lightning continued relentlessly to penetrate the body of Erase.

In the absence of control from Yeruashi, Ryton began to naturally affect his flesh, but due to the proper degree of concentration, the cells were not damaged.

During the irritation and stimulation of the flesh, Yeruashi felt heat all over his body, it seemed that every cell in his body was being tempered by Raiton.

"There seems to be no problem with this, the degree of concentration is satisfactory....then it is necessary to adapt, gradually increasing it, until every cell in the body adapts to Ryton..."

After analyzing his condition and finding no problems, Yeruashi closed his eyes and activated the five-fold acceleration state of the time stream.

The other day, his ability to accelerate the flow of time improved, the upper limit increased by one more unit.

But the new ability was never unlocked. Although the fog surrounding the Roman numeral three is gradually dissipating, it doesn't look like this process will end any time soon unless there are some unforeseen changes.

Crack!!

If you look at Yeruashi from the side at this time, you can see that the arcs of lightning intertwining on the surface of his body began to behave a little strange, their number increased dramatically by several times.

The arcs of lightning that enveloped and permeated Yeruashi's body were moving at normal speed, but the speed of their generation had increased dramatically.

At the time of loss of control and contact with aggressive lightning chakra attribute of the Ryton is the ability accelerate the flow of time, in fact, this is equivalent to the release of the usual Litonjua, but he is Erase continues to be in an accelerated state, which leads to generation of a larger number of Ryton.

Being in a state of accelerating the flow of time, the flesh can normally tolerate the impact of an increased amount of aggressive lightning. The speed of practice has increased, but this acceleration is not just equivalent to the degree of acceleration of the time flow, everything is much more complex and cannot be accurately calculated.

In three days.

Erase has completed the initial phase of hardening.

After spending some time adjusting Ryton's concentration, he moved on to the next stage.

As time passed, he continued to increase the degree of concentration. Passing through the hardened flesh of Erase became more and more adapted to Ryton.

As he continued to practice, Yeruashi confirmed his assumption that Raiton's Flesh-Hardening Techniques actually had an effect on the Thunder Gate!

After practicing for about a couple of weeks, Yeruashi noticed that the damage received by the body when opening the Thunder Gate was noticeably reduced. Now, when opening the fourth gate, he doesn't even need to use the time-reversal ability to recover, the body is able to neutralize most of the side effects on its own.

"Now I really have hope for the opening of the eighth gate."

Yeruashi nodded in satisfaction and whispered.

He had previously concluded that he would probably not be able to open the eighth gate, because after opening the third gate, the time and effort required to open the next one began to increase too much. By the time the sixth gate opened, his body would be about twenty years old, and by the time the seventh gate opened, he would probably be over thirty.

Although he relies on the ability to accelerate the flow of time to open the gate faster, it also accelerates the aging process of the body, and if you try to neutralize this effect with the ability to reverse the flow of time, the results of training will be canceled.

When the age crosses the thirty-year mark, the shinobi can only continue to develop the spiritual aspect and build up the skill, but the physical body can no longer be improved.

Until the age of forty, you can continue to maintain your physical condition at its peak,and then it will gradually deteriorate.

If a shinobi practicing Hachimon Tonko doesn't open the eighth gate before the age of forty, he will probably never be able to do it again, because his physical fitness will begin to decline.

Only a few are able to open the eighth gate.

The vast majority of practitioners will be stuck on opening the seventh or even sixth gate.

But having mastered the Technique of Tempering the Flesh with Raiton, Yeruashi found hope for the opening of the eighth gate, because the practice of this technique can significantly facilitate this process!

Perhaps this practice would take a long time, and it would take more than a year to reach the required level, which would slow down the Thunder Gate practice in the short term, but in the future, it would allow him to reach the eighth Gate!

Opening of the eighth gate.

For Erase this means becoming invincible.

Opening the eighth gate in a state of accelerating the flow of time, not to mention Uchiha Madara, even if Kaguya gets in his way, she probably won't be able to withstand a couple of blows!
