Laying Low in the Hehuan Sect, I Prove the Great Dao Through Yin and Yang

[No System] [Decisive and Ruthless] [Never Gets Pushed Around] Shen Li, a lowly office worker who has just transmigrated, suddenly discovers that he has become the lowest-ranked furnace vessel in the demonic Hehuan Sect, a useless piece of trash! His daily task is to help the sect's disciples cultivate through yin-yang union, absorbing the yang energy from their bodies to boost his own cultivation. His predecessor had just been drained to death, giving him the chance to transmigrate. This is bad, this is really bad! Is he going to be drained to death by the demonic sect's disciples just like his predecessor? Just as despair takes hold, a battered little cauldron appears in his dantian. The Yin-Yang Creation Cauldron contains a Pool of Yin-Yang Creation. It can devour and absorb the energy of yin-yang union, returning double the energy to him, and can also copy one of the other person's spiritual roots. With the Yin-Yang Creation Cauldron in hand, Shen Li keeps a low profile as he steadily grows stronger. Then one day, he suddenly realizes that he has become invincible!
