Rebirth: After Being Buried Together, I Sent My Mortal Enemy to the Throne

[Double heroines + dual lives + 1v1 + a little trickery] The scolding little troll Yan Chen vs. The half-blood Shirogiri Heiroku Princess who has been secretly in love for many years Jiang Yuemian is an old monster who has lived for a thousand years. One day while going down to the grave, she dug a joint grave. A closer look revealed that it was the tomb of Wen Shuyao, her sworn enemy from a thousand years ago. She was ready to loot all the burial objects of her sworn enemy. Suddenly, I realized why this man buried her with her, Jiang Yuemian's clothes. The "wife" buried together in the tomb is her, Jiang Yuemian, and her mortal enemy? Her nemesis likes her? She was about to give it a good stroke when she was hit in the back of the head by a boulder and fell into coma. After waking up, she went back to when she was 20 years old. The system in her mind told her that her mission was to assist the Sixth Princess in ascending the throne. Alien blood? Ascend to the throne? Jiang Yuemian: Can you go back? I can't do it, I will turn into Momo. But why did Wen Shuyao ascend to the throne before she had done much?
