Since the beginning of Jianghu, people in Jianghu have been roughly divided into two categories, righteous and evil. However, justice did not defeat evil, and the world was controlled by the Demonic Cult. Sixteen years later, when the leader of the Demon Cult, "Domination", selected "Tian Xia", the elder sister of his twin daughters who inherited his gift of photographic memory in martial arts, as his successor, this decision completely aroused the sister "Number One"'s jealousy of her sister and hatred of her father. In order to become the leader of the Demon Cult, she did not hesitate to plot to harm her sister and imprisoned her father. However, Tianxia did not die. She was rescued by "Hope", the son of the leader of the Shande sect, the largest gang fighting against the devil at that time, but Tianxia lost her memory. During a sneak attack by the Demon Cult on the Shan De Sect, the Demon Cult members discovered that Tian Xia was not dead, so after learning the news, they immediately sent people to hunt down Tian Xia...
Can Tianxia regain his memory and escape pursuit? What will happen to the Demonic Cult in the end?
