In the deep ancient palace, candlelight flickered, Yun Heng picked up a bone jade that had been buried in dust for thousands of years, and his fate was deeply shadowed since then. Unlike the world's people who strive for immortality, he can hear the whispers of the dead and feel the mournful cries of ghosts. Every midnight, Yun Heng wanders through the gap between the human world and the underworld, unraveling obsessions that have been forgotten by the world, and also glimpses in the darkness the other side of the path to immortality: only those who protect the souls of the dead can truly inherit it.
But as the bone jade in his body gradually awakens, the ancient will in the darkness begins to revive, and the forbidden power that was once suppressed is ready to move. Yun Heng had to choose between the guidance of the ghost and the rejection of the fairy gate, struggling between light and shadow. His pursuit has long gone beyond becoming an immortal, but to uncover the forgotten truth behind reincarnation - who is controlling the fate of all living beings? Who is destined to bear the ancient curse?
The intertwining of spirit and flesh, the dance of good and evil, Yun Heng's path of cultivation is destined to be a lonely exploration dancing with the netherworld.
