บท 638: Discovering Trace

Bei Feng was unmoved as he focused on the fifth section of his spine.

Large amounts of golden blood appeared from the silverish blood, forming a new piece of spinal bone.

The new bone was golden, filled with intricate patterns.

Bei Feng's aura began rise rapidly as his cells transformed. As soon as the spinal bone was formed, the blood that flowed from it became golden.

Originally, the percentage of golden blood in Bei Feng's body was already 30%, but in the instant that the fifth section of spinal bone was remolded, it'd reached 35%!

Bei Feng looked at the small increase in golden blood in his body, and muttered to himself, "Looks like it'll be harder and harder to form more golden pure Yang blood Qi the further I advance. It might not be possible to completely change all my blood into the golden one in the Thousand Year King realm."
