After Being Reborn and Exchanging Marriages, I and King Li Jianxian

Rebirth? Rebirth! Rebirth? In her previous life, Qi Jinxi accidentally married into the Pei family, and her children both died unexpectedly. Her husband just did nothing for the sake of his concubine, and even said that the children were not his children. With all her thoughts in despair, she burned down the entire Pei family. In the blink of an eye, she was reborn. A system that claimed to accompany her mother told her that it was her mother's points that allowed her to be reborn, hoping that she would have a new life and a new way of living. However, she felt that something was wrong everywhere around her... There is another reason for the marriage exchange. The half-sister seems to have memories of past lives? The guard who used to be by his side appeared in advance, and even had a new identity? There seems to be something wrong with me. What do I always forget? "You? You want to marry me?" "Axi, can you trust me?" "Axi, if you don't want to marry me as your princess, then I can go to your princess's mansion and be your princess, okay?" In this life, Gu Chengyuan doesn't want to make the same mistakes again, he just wants to be A Xi day and night.
