I'm so Pregnant, My Dear, I've Seduced the Powerful Ministers into Submission.

Shen Zhiyi has been married to Xie Sian for three years, but the marriage has not yet been consummated. Her mother-in-law drugged her and sent her to her husband's bed in order to have a legitimate grandchild. But her husband abandoned her like a worn-out shoe, called her a slut, and even left her to a servant. She broke into Xie Changyan's yard with hatred. Mr. Xie: "Do you know what you are doing?" Shen Zhiyi: "I know, give birth to a child for the eldest brother. Anyway, their surname is Xie. It doesn't matter whose it is. Third Master, please help me." Shen Zhiyi didn't want to, but they forced her to a dead end, so she had to live for herself. Fortunately, the cold-hearted uncle helped her give birth to her eldest son with a cold face and a warm heart. She thought the child's surname was Xie, but why did he end up with the surname Huang?
