When he was twelve years old, my grandfather used a drop of his heart to sign a blood contract for his grandson who was afraid of the dark. The guardian spirit is a drowned girl named Liu'er.
From then on, there was a shadowless girl beside young Wang Niansheng. She watched him grow up, accompanied him to travel across mountains and rivers, and slayed demons. He taught her to feel the warmth and coldness of the world again, and she protected him from the disaster of life and death.
But Liu'er is a ghost. No body temperature, no heartbeat, no shadow in the sun. This is the iron rule that humans and ghosts follow different paths, and it is also the gap between them that can never be crossed.
The countdown to the Ghost King breaking the seal has started. Thirty years later, Wang Niansheng will face not only a life and death battle, but also a choice that is destined to be unsatisfactory——
Should she keep her identity as a person, or become an "existence" like her.
