Swap Relatives? I'll Leave It to You, and I'll Go into the Palace and Become a Queen.

Shen Zhiyi and sister-in-law Shen Yunzhao were both reborn. In this life, my sister-in-law begged to marry a poor scholar first, "giving" her the opportunity to enter the palace, and waited to see her die in the palace. Shen Zhiyi smiled. Sisterly love is deep, right? Give it to you. She didn't know that the poor scholar from the Gu family could indeed be granted the title of Marquis and Prime Minister—— But his mother can peel off the skin of his daughter-in-law, his sister can make her sister-in-law mad to death, and there are all those shady secrets... As for entering the palace? The emperor came to her every day and looked at her more and more wrongly. Later, the eldest sister knelt down and begged her for help. Shen Zhiyi touched her belly: "My sister gave me a good marriage, and I will give it back to you."
