World view setting
The Time Management Bureau has a "Time and Space Restoration Department" to repair key nodes in history through special media. The restorer needs to hold the "time token" to carry out the work, and each time he travels through, the vitality of the token's related objects will be consumed. Ginkgo leaves are a symbol of time, and broken veins can cause memory dislocation.
Time and space restorer Jiang Yan and inspector Shen Zhao met at the Time Management Bureau. When they jointly performed the task of restoring history, they discovered that there was a mysterious connection between each other's memories. The cracked celadon from the Ru Kiln of the Northern Song Dynasty, the flame poetry paper from the Bookstore of the Republic of China, and the gilt chime bell from the Music House in the prosperous Tang Dynasty, these three time and space tokens lead the two people to the core truth of the corridor of time.
As the mission progresses, Jiang Yan discovers that Shen Zhao arrives at the accident scene early every time, and the copper key around Shen Zhao's neck can actually open the secret room of his childhood fire memory. When the thousand-year-old ginkgo bloomed and withered at the same time, the two finally understood that the so-called restoration of time and space was just looking for the possibility of reunion in seven hundred and twenty reincarnations.
