A Zhu, the lantern keeper at the Forgotten River Ferry, holds a mysterious glass lantern. Over the past three hundred years, the strange movement of the lamp wick has broken the peace of the underworld. The originally pure blue flame turned into scarlet, and a flower bud emerged from the lamp. Inside the bud was the vague appearance of the young girl who was swallowed by the flames a hundred years ago.
As the black fireflies bring rotten odor and memory fragments, Wu Jiu, wearing a bronze mask, appears to collect debts. The words of the old shipowner reveal the past that was lit with the soul of Qing Heng a hundred years ago. When Qing Heng's soul was reborn in the lamp, A Zhu faced a difficult choice: abide by the law of equivalent exchange, or break the law and take her away.
And behind all this, there is an even more amazing secret. The sacrifice a hundred years ago was not as simple as it seemed, but a murder involving seven lives. The glazed lamp was actually a fire of resentment guarding evidence of guilt. A Zhu and Qing Heng are struggling in reincarnation and the truth. Their fate is closely connected with the glass lamp. In the fog of Wangchuan, the two will face Lord Ming's chess game together, uncover all the mysteries, and find their final destination.
