When the only clue to his father's disappearance for three years - a mutton-fat jade pendant engraved with "Abyss" and a blood-stained map of Longyuan Valley appeared at the same time, ancient book restorer Chen Yan was forced to step into the cursed and forbidden place. It is said that the Abyss Jade Box contains the power to control people's hearts, which needs to be guided by the "Eye of Dragon Abyss", "Blood Pattern Key" and a sacrificial soul. The disappearance of the father and the cause of the death of the mother are closely connected with this jade box.
The fog in the valley swallows the direction, the "echo" connects the obsession, the masked box keeper, the scarred man whose identity is a mystery, the shadow of constant betrayal... Every step is on the edge of truth and lies. When Chen Yan discovered that the so-called "sacrifice" was actually a scam spanning three generations, and that he had already been the vessel chosen by the abyss, he had to make a choice between saving his loved ones and protecting himself - should he open the jade box and release the darkness, or cut off the chains of fate with his own hands?
