In the bizarre modern city "Floating City", young antique restorer Lin Weilan guards a small shop called "Zi Xin Zhai", maintaining a peaceful life with his ingenuity in restoring cultural relics. She is good at catching glimpses of fragments of history from damaged utensils, but she avoids talking about her vague childhood memories and an unsolved case left by her family. Until a bizarre "curse of ancient mirror" incident broke into her life - a Qing Dynasty bronze mirror accidentally caused a series of strange accidents during restoration, and all clues pointed to an archaeological project that the Lin family suddenly interrupted twenty years ago.
At the same time, the mysterious and low-key Shen Yanzhi appeared in Floating City as an "ancient book researcher". He seemed to know Lin Weilan's past well, but he was secretly investigating the forces related to the Lin family's old case. As Lin Weilan continues to discover hidden secret messages, symbols and tampered history in the process of restoring cultural relics, she is forced to be involved in a conspiracy that spans decades: the mysterious death of the archaeological team, the concealment of the family elders, the secret manipulation of the powerful people in the floating city... Shen Yanzhi's attitude of being both good and evil and his repeated acts of helping make Lin Weilan waver between trust and caution. In the process of tracing the truth, the two not only have to decipher the codes hidden in the antiques, but also face threats from reality and inner fears. When the dust-laden secrets were gradually revealed, Lin Weilan discovered that she was not only a bystander to the family story, but also the key to solving all the mysteries. Shen Yanzhi's true identity and his deep connection with the Lin family's old cases are also gradually revealed amid layers of fog.
