Gu Che, a young social worker, accidentally inherited an abandoned scenic spot far away from the hustle and bustle of the world - Cuiying Lake Resort. Thought he was just inheriting a pile of broken bricks and huge debts, he soon discovered that this huge ruin was far from as dead as it seemed.
In the empty management office, an ancient music box that had been carefully wiped automatically played sad music; deep in the uninhabited wooden building, an old hidden mirror reflected a pale figure that should not exist; the door leading to the underground was crazily hit by an invisible force in the middle of the night, accompanied by a whisper full of resentment...
Curiosity-seeking Internet celebrities, weird acrobatics classes, and profit-seeking e-commerce platforms have barged in one after another, trying to extract value from this desolate land. However, like pebbles thrown into a deep pool, they have disturbed the "things" sleeping here layer by layer. Gu Che gradually realized that what he inherited was not property, but a heavy curse, a terrible duty from the family lineage to guard the "Xujie".
Deep in the center of the lake, the muffled sound of chains being dragged becomes increasingly clear, and the shadows in the mirror get closer and closer. When the ancient seal gradually fails and the suppressed terror is about to awaken, Gu Che must find a way to survive in this forgotten land, or be buried with it.
——What you inherit is not an inheritance, but the duty to guard the abyss. When the final sonata sounds, will it awaken the sleeping terror, or become the eternal night watchman?
