Seven hundred years ago, the magic lamp in the sky fell into the Sea of Embers, and the "night tide" began to exist in the world. When the night tide comes, the dead will knock on the door, forgotten sins will be resurrected, and the town must rely on the "everlasting light" to dispel the strangeness.
The young man Xu Zhaoye was born into the lamp-shou sinner clan. Ten years ago, his father disappeared in a light disaster and was considered a traitor by the world. Xu Zhaoye guards a broken lantern building in a border town and makes a living by lighting soul lanterns for the dead. Until one night, the lights in the town went out, and my father, who had been dead for ten years, came home carrying a black lamp and said, "Don't believe in the lights in the sky."
From this moment, Xu Zhaoye was involved in the huge whirlpool of the magic lamp falling into the sea, the secrets of the dynasty, the annihilation of the lampkeepers, and the resurrection of the corpse deep in the sea of embers. Along the way, he meets the cold-hearted female swordsman Wen Shuang, the prince Xie Linchuan who hides his sword in his smile, the girl A Luo who carries demon blood, and a group of people who all have their own scars.
He originally thought he was going to clear his father's grievances, but later he discovered that his father was not a traitor and the lampkeeper was not a criminal. The real betrayers of the world are those who sit high in the clouds and feed darkness in the name of light.
