[No System, No Golden Finger, Slow Burn, Ghost Cultivation, One Female Lead, Careful Planning, Lay Low when it's wise and act without hesitation when it's time]
Wu Xuan transmigrates only to be targeted by a female ghost and reduced to the lowest kind of ghost slave.
First, he takes control of a ghost domain and scares to death the bandits lurking near his corpse, then devours their blood essence.
After breaking free of his status as a ghost slave, he plots to destroy the evil spirits and vengeful ghosts who controlled him.
He later possesses Zi Qingyan, the young master of the Zi household, and cultivates as a ghost cultivator.
Through a stroke of luck, he exposes the Seventh Prince's scandal of refining pills with the bodies of young boys and girls, helps imperial envoy Wei Huaiting control a flood, and joins the Purple Condensation Immortal Palace as a descendant of the Zi household, beginning his path as a ghost cultivator.
In a cultivation world that treats ghost cultivators as mortal enemies, he advances carefully, transforming from the lowliest ghost slave into the revered True Lord of Divine Darkness.
The mysterious veil covering this world is gradually lifted.
The immortals sit high above, preying on the people and devouring all living things, heedless of the collapse of the Heavenly Dao and the ruin of reincarnation.
Yet one lone ghost cultivator must rebuild the Underworld, protect countless souls, ascend the tower to become an immortal, and restore the Dao with his own body.
