When they opened their eyes again after five hundred years, the two people exchanged fates - the Sword Immortal became Su Xiaojiu, a useless disciple of the Immortal Sect, with a broken spiritual root and suffered all kinds of humiliation; the Demon Lord became A Ying, a low-level servant of the Demonic Path, who was poisoned and his life was hanging by a thread.
What's even more terrible is that a soul contract of life and death binds the two together. If one loses, both will suffer. If one party dies, the other party will be buried with him.
The former rivals who fought to the death are now forced to work together to survive.
