The magical art was complex, and he had to maintain it for an hour. Li Ming could immediately feel how difficult the task was going to be.
He had obtained the [Yin Fire Bead Chapter] from Liu Mengyun and it was used to refine the yin fire bead he obtained from demons.
Ignorance could sometimes be the most terrifying thing.
Li Ming did not even consider whether or not he could refine the yin fire bead with his current cultivation. He simply followed the method in the [Yin Fire Bead Chapter] and carefully began to refine a yin fire bead.
Mysterious symbols continuously shot into the stalagmite fire and penetrated into the yin bead.
However, whether it was the stalagmite fire or the yin bead, they did not experience any changes.
As time passed, fine beads of sweat began to seep out of Li Ming's forehead.
The consumption of spiritual energy was just too much!
