Kokushibo froze again.
This technique suddenly gave him a strange feeling.
For a moment, he could not tell which Breathing Style it was.
This charging technique had something in common with every Breathing Style, yet it was not any of them.
A tremendous amount of oxygen flowed along the paths of Su Chen's breathing, the air entering his lungs.

Bright, dreamlike, dazzling.
The light suddenly made Kokushibo feel as though a lifetime had passed.
