Chapter 641: Lei Dun Body Tempering and Five-Fold Speed

Using the Lei Dun Chakra secret technique to forge and hone the body, in his view, had a high probability of reducing the difficulty of opening the Eight Gates and shortening the time required to open them.

After all.

The Eight Inner Gates he used were no longer the pure Eight Inner Gates, but the Eight Gates Lei Dun formed by using Lei Dun chakra to impact the gates!

Inside the canyon.

White lightning intertwined and exploded at the bottom.

Lu Chen glanced at his arm, which had been scorched by the exploding lightning, and shook it; the scorched marks quickly faded, returning to a fair and undamaged state.

"It's a bit over-concentrated... I need to continue adjusting..."

After Lu Chen pondered for a moment, he spread his palm, and lightning-attribute chakra flowed across his arm once again. He quickly compressed it, forming a flowing shape that adhered to and coursed through the inside and outside of his arm, then he released his control.

Crackle, pop!!

The lightning exploded again, and his arm was injured once more.

"The amount of chakra is still too large; I need to reduce it a bit more..."

Lu Chen's expression remained unchanged. After using Time Reversal to heal the injury on his arm, he continued his attempts.

The Lei Dun Body Tempering secret technique is a secret technique that uses lightning to stimulate somatic cells. It is not like Chidori, which simply flows on the surface of the palm or weapon; instead, it surrounds and intertwines through the entire interior and exterior of the arm.

And unlike Chidori, during this process, one cannot exert control over the lightning-attribute chakra, because if control is exerted, the lightning-attribute chakra will not form a stimulus to the body but will instead evolve into an ordinary Lei Dun ninjutsu.

The key to the Lei Dun Body Tempering secret technique is to create a portion of lightning-attribute chakra with the most appropriate 'amount,' and then release control over this portion of lightning-attribute chakra, allowing it to turn into lightning arcs and naturally erupt inside and outside the body.

This amount needs to be controlled very subtly. ===== CHAPTER 643 =====
