Archaeologist Lu Zi accidentally triggered a mechanism during an ancient tomb excavation and traveled to the modern city. On the surface, he appears to be a gentle antique shop owner, but in fact, he is taking every step of the way, using knowledge about the future to plot revenge. His former best friend Zhao Heng pushed him into a grave in order to seize the family property. Now Lu Zi returns and vows to uncover the truth of the past. Under the strong suspense tone, he and the cool policewoman Su Wanqing went from testing each other to solving the problem together, weaving a love network in a series of mysteries. Every unsolved case points to a conspiracy from twenty years ago, and Lu Zi's "white and black" nature is gradually revealed - he is both a victim and a hunter who controls the overall situation. When the truth approaches, the betrayers will eventually face the judgment from the depths of time and human nature.
