บท 459: Chapter 459: Pill Refinement Mastery, Peak Grade Fifth Revolution

Ning Fan touched the large green wooden cauldron. His palm felt a cool and heavy sensation from it.

The power of his medicine soul condensed into a vortex at the center of his palms. The thick medicine qi trapped inside the large cauldron was being absorbed by the vortex and it fused into his medicine soul.

The green color on his medicine soul became fainter while the color of black became more concentrated.

The blackness began to spread nearly all over his medicine soul. Ning Fan knew that if the color of black covers his medicine soul entirely with only a tinge of green left, would mean that his pill refinement mastery had advanced to the Peak Fifth Revolution.

Green was the color of a Fifth Revolution medicine soul, black was for that of a Sixth Revolution medicine soul and purple was for a Seventh Revolution medicine soul.
