Invincible Villain, I Am Evil

Who says the villain is just a stumbling block for the protagonist? Who says villains can't become emperors? When faced with a choice, Li Wuji chose to cultivate demons! But the system also has its own Xiao Jiujiu. In order not to be destroyed by the main system, he is willing to accompany Li Wuji and become the villain of the system. In order to prevent the plot from becoming so cruel, as he was besieged and killed by all the protagonists right away, the system allowed Li Wuji to be born into the Li family in Wuling City. With the Eternal God and Demon Body, Li Wuji can not only practice the righteous arts, but also practice the evil arts of the demon clan without any backlash. While others are working hard to cultivate and grab resources, the system is protecting the master tyrannically, and occasionally issues some tasks, all of which are god-level skills or heaven-level skills, helping Li Wuji become a peerless emperor!
