During the day, Gu Yesun is the most famous antique restorer in Lancheng. A pair of skillful hands can restore broken time treasures to new life. He lives a plain and warm life with his five-year-old daughter Gu Qinghe alone.
However, whenever night falls, he will hold up an ancient bronze lamp and become a "spiritual man" wandering in the shadows of the city.
This ancient lamp named "Du Ling" is the destiny of the Gu family passed down from generation to generation. It has no smart panel and will not issue tasks. It will only use the most primitive methods - temperature, light and shadow, and even resonance to guide Gu Ye to find those "reverberations" that are bound by obsession and linger in the world.
What he has to do is not to slay demons, but to listen, understand, and personally make up for their regrets during their lives, and light up the last journey to rest for them.
Originally, this was his only secret. Until one day, my daughter Qinghe pointed to an empty corner and said in a childish voice: "Dad, was that aunt crying in the corner the one you brought home last night?"
Gu Yesun's world was suddenly reconstructed at that moment. He not only wants to protect the boundary between man and spirit, but also protects his unique daughter who can see everything.
Under the neon lights of this bustling city, there are countless unknown joys and sorrows hidden. And Gu Yesun and the light in his hand will be the only warmth in the eternal night.
