However, this idea was still difficult to achieve.

Currently, Qin Feng's《 Primordial True Dragon Technique》 had reached its limit. For a bottleneck, simply wanting to break through to the Tenth Perfection was very difficult.

"Looks like I can only try out this astral wind …"

Astral winds were a type of wondrous wind. It existed in certain s.p.a.ces in the void and was all-pervasive. If one encountered it, they could almost reach the point where all living things could be destroyed.

Compared to the gale and gale released by the martial cultivation, it was even more terrifying and astonis.h.i.+ng.

"Phew!"

Qin Feng slowly exhaled a mouthful of impure qi. With a slight movement of his fingers, he extended his palm out of the cave.

"Pa Pa Pa!"

In the blink of an eye, Qin Feng's body stiffened. Not only that, that terrifying astral wind was even more so as it swirled around Qin Feng's palm.

"Hiss!"

The intense pain and the freezing feeling caused Qin Feng to feel as though his body didn't belong to him at all.

swish *

"Boom!"

The astral wind and icy aura quickly appeared outside of the cave and fiercely collided with each other. The terrifying force caused the mountain to constantly tremble and rocks to roll down.

"Refine …"

The blood energy filled up and forcefully turned into a scorching energy that circulated around his body. Relying on the huge amount of energy nouris.h.i.+ng his body and his blood energy, that cold energy was quickly refined into nothingness by Qin Feng.

Only strands of astral wind remained within his body.

He wanted to master the characteristics of this astral wind, and the best way was to merge with it, and then let himself become like the astral wind. He wanted to master the characteristics of this astral wind, and the best way was to integrate with it, and then let himself become like the astral wind.

"Roar!"

However, the moment Qin Feng began to comprehend this astral wind, it was as if the astral wind had left the reins and fiercely galloped into Qin Feng's body.

Face, neck, arms... The muscles all over his body showed signs of twitching.

At this moment, Qin Feng's skin, flesh, tendons, bones, and marrow … Everywhere he went, he was being tormented like he was in purgatory.

"You … "Master!"

Qin Feng, who was curled up on the ground, howled with all his might.

This kind of feeling was enough to make one go crazy.

"Puff …"

He couldn't help but spit out a mouthful of blood.

This mouthful of blood was astonis.h.i.+ngly powerful, and carried with it an intense aura of tearing. It had actually ruthlessly pierced a deep hole in the ground.
