Su Haitang, a modern cultural relic restorer, was involved in a rift in time and space while repairing a box of ancient rouge inscribed with "Misty Rain Pavilion" and fell into the turbulent Republic of China. The rouge in her hand is the token of the secret place "Misty Rain Pavilion" in the Jianghu, which contains a treasure map that can overturn the current situation. Chu Yichen, the son of a warlord who was ordered to track down the secret treasure, met her unexpectedly during the hunt - the jade pendant around his neck matched perfectly with the rouge box she brought.
As Rouge's Begonia was stained with blood in crisis after crisis, the two discovered that this box of Rouge not only bound them to fate across time and space, but also hid a mystery of life and death that the previous generation had not been able to solve. When the mechanisms of Yanyu Pavilion are opened layer by layer, they must not only fight against the pursuit in the dark, but also face: Is this time traveling an accident, or is it a reincarnation that has already been written?
