{Su Xiao}, a recent graduate, rented a cheap rental house in the old city, only to find that the wardrobe was a crack connecting different time and space - sometimes the green bricks and black tiles of the alleys of the Republic of China appeared, sometimes the neon raindrops of the future city came, and even the brocade of the ancient palace could be touched. In an accident, she broke into the Republic of China to rescue a female writer who was being hunted, and received a "time and space diary" as a gift. Only then did she learn that the wardrobe is the "time and space anchor" that maintains order. Once destroyed by an evil organization, the entire city will fall into time and space turmoil. In order to protect her home, Su Xiao teamed up with a professor from the history department next door to use the code book brought back from the Republic of China, repair fluid obtained from the future and other items across time and space to set up a "time and space barrier" in front of the wardrobe, successfully preventing the crisis. The wardrobe finally returns to its normal style, but the time and space diary in the drawer still hides the unfinished secrets of time and space.
