In The Age Of Rebirth, Orphan Girls Have Space

After her grandfather passed away, Lu Xiaoxiao, a girl living in the 23rd century, lived alone in the villa left to her by her grandfather, regardless of their relatives' disapproval. Suddenly, she discovered that her grandfather had left a space for her. She loved reading novels and started hoarding supplies for fear of the end of the world. When she ran out of money and planned to take a break, she was reborn in a place called Huaguo in the late 1950s and became the body of an 8-year-old girl named Lu Xiaoxiao, whose parents both died. Fortunately, the space has come with us, and I can live a good life even in this strange era (a one-on-one pampering story, the male and female protagonists are both clean, so feel free to enter the trap)
