Chương 305: The Blood Poison Gang 

Not to mention, the Broken Axe Gang had already been wiped out by him. There were no additional methods to obtain it. 

Similar to him, it was probably the rumbling thunder technique. The rumbling thunder technique, which was only at the fourth refinement level, was also somewhat useless. Although it had a reaction with the nine dragons true qi technique, its level was too low.

Qin Huai finally decided to refine the broken axe technique first. As for the rumbling thunder technique, he would have to wait and see. 

He closed his eyes and slowly activated the divine power book of a thousand creations, throwing the broken axe technique's blood essence into the ancient book. However, this refining process took a long time, so Qin Huai had only refined five layers in one night, allowing the nine dragons true qi technique to increase by another one percent, reaching six percent.
