There are laws in every world. The laws ensure the stability of the world's timelines. When the laws are destroyed, loopholes will appear one by one. Managers born from the laws have to repair the loopholes and find out the reasons for the disappearance of the laws.
When managers cannot find the reason for the disappearance of the laws, they can only choose to restart the world, experience the new world system again, re-establish the laws, and maintain world stability.
Xihan is the manager of the world where the rules suddenly failed. After re-establishing the system, he abolished his own cultivation and memory, starting from the first timeline, and re-wrote the rules. Without memory, if the manager still cannot solve the problem at the end of all timelines, the manager will be destroyed along with the world.
Ling Ao followed his master Xihan into the timeline to find and rebuild the world.
