In the last years of Dayin, demon disasters occurred everywhere. In order to buy medicine for his master, Xie Zhao, the last disciple of Qingyang Temple, joined the Demon Suppression Department as a night patrolman. On the first night after joining the company, he was locked into Yizhuang by his colleagues and faced alone with the evil spirit of the five internal organs, which also awakened the Thief of Heaven. From then on, every normal attack may steal the enemy's energy, blood, martial arts and magical powers. Others kill monsters to get pills, but he regards the monsters as treasure houses. When the demon tide sweeps across Kyushu, Xie Zhao steals all the demons' life treasures with one sword strike and walks out on his own path to immortality.
