Ling Feng, inside the Bamboo House, knew nothing of Queen Medusa and Zi Yan's visit. At that moment, he had already entered the crucial stage.
As Ling Feng refined it step by step, streams of scorching, invisible energy surged around him. Like long, unseen serpents of searing heat, they coiled over his body before following his breaths inside.
Under the ceaseless infusion of energy from the fallen heart flame, rapid changes were taking place within Ling Feng's body.
