In Cangxuan Continent, the boundary monument changed. Ten thousand years ago, the Demon Lord was sealed by the gods with a demon sealing formation and fell asleep at the foot of Fuzhou Mountain. He set a curse before sleeping. He will come back ten thousand years later. At that time, Cangxuan Continent will sink into the dark sea and never see the light of day again. After Yu Lan's death, he happened to be reborn on Shangguan Lan who died in Fuzhou. Shangguan Lan was originally the carrier of the Demon Lord's resurrection and was given immortality in Fuzhou.
