Two Months

Wen Leyang's body has been upgraded twice now. It was only after the Yin and Yang forces have been fused completely that his actual power received a qualitative leap. The Poison of Life and Death in his body has absorbed the utmost poisons of the Five Elements but this had only enhanced the Yang's disposition in him. In order to really upgrade himself, he still needs an equal amount of malevolent Yin forces from the Corpse Poison as a supplement. 

This matter was directly related to his cultivation method and actual power. Wen Leyang's heart wavered from unease as he listened to the explanation. It took him a moment before he reacted to the situation and asked Guo Huan, "Why had you not told me that earlier?" Guo Huan had pretended to be comatose all along yet he seems to be able to speak impressively with sound reasoning right now. It was certain that he had spent some time pondering on this matter in the past.
