The Reborn Aristocrat's Daughter

Situ Xin was highly intelligent, but because she had been an orphan since a young age, she was quite unemotional.
During her last mission, she was betrayed by "one of her own." As her soul was in the process of Soul Formation, she was saved by the Phoenix Jade Pendant she wore, allowing her to be reborn as a fetus in her mother's womb. Moreover, she carried a space with her.
Let's see how she lives a different life after being reborn in 1988.
