In the 23rd century, a girl named Lu Xiaoxiao lived alone in the villa left to her by her late grandfather. Her parents ignored her, and her relatives hated her. Suddenly, she discovered a hidden spatial pocket within the jade pendant her grandfather had left her. Being an avid reader, she began frantically accumulating material possessions, fearing the arrival of the apocalypse. Just as she was about to run out of money and planned to take a breather, she fell asleep and woke up reborn in a place similar to the 20th century, as an eight-year-old girl with the same name whose parents had passed away. Fortunately, the hidden spatial pocket had come with her, which allowed her to lead a fulfilling life even in this unfamiliar era.
