Chu Zhao was originally the son of the last mausoleum keeper of the Great Xia Kingdom. He was born at a time when the world was about to collapse in troubled times. Twenty years ago, there was a supernatural riot around the world, the earth's veins collapsed, and Yin Qi poured into the stars. All nine kingdoms were destroyed, and only the remnants of Daxia were left to survive within the "Secret Ruins Barrier".
When he was eighteen years old, Chu Zhao was ordered to enter the ancestral mausoleum to turn on the "soul-suppressing lamp", but was betrayed by a traitor and sacrificed to the ancient evil god "Thousand-faced Lord of the Underworld". His body was burned and his soul was dispersed.
When he was reborn and returned, he was no longer a human being—but a spirit of the dead who had crossed the 30,000-year time gap and crawled back to the present moment from the mountain of corpses in the future and the sea of blood.
