The overworked programmer Qin Jian suddenly died after working non-stop for several days. His soul transmigrated into the body of a provincial official in the Tianyuan Dynasty. He thought he find himself a pretty wife and enjoy life in the official mansion. But it turned out he was given the Heaven's Eye ability, which allowed him to see demons and other spirits. In fact, he's been sleeping with a major demon the whole time, which made everyone think he's a dangerous demon, too. Now he has to live with all sorts of demons, as he starts on a fantastic journey of demonic cultivation. (Source: Kuaikan, translated)
