Chen Nan killed Nangong Ye and suddenly thought of a divine skill regarding the Blood Transformation Technique found in the memory he seized from an Earth-level killer before. He regretfully licked his lips; unfortunately, the Heaven and Earth Unification move was too strong, directly turning Nangong Ye into minced meat.
This Blood Transformation Technique can absorb the blood qi within a cultivator to strengthen oneself. What's more, it can absorb seventy percent of the opponent's power for one's own use. However, the side effects are significant; this additional seventy percent power can only last an hour, after which it rapidly wanes, leaving one even weaker than before.
But for an assassin, the most critical part of an assassination is just a few breaths of time, so an hour is quite sufficient.
