He Demotes His Wife to a Concubine and Expects Her to Endure It? She Turns to the Regent

[Reborn woman vs. transmigrated woman + demoting a wife to concubine + groveling to win her back + no reconciliation after the relationship breaks + political intrigue] In her previous life, Lin Ruotang used her dowry to start a business and support the marquis's household. She built a new residence and helped Sheng Yan enter government service, making him one of the capital's rising stars! Yet he despised her low birth as the daughter of a concubine. While she was pregnant with their first child, he coaxed her into drinking a potion that would make her infertile. After she miscarried, she could never conceive again. He used this as an excuse to bring Lin Ruyue into the household as his wife, demoting Lin Ruotang to a concubine. Worse, he falsely accused her of having an affair with his younger brother, then drowned her in a pond in the dead of winter. Reborn, Lin Ruotang decides to plan carefully and live for herself! Demote her from wife to concubine? She divorces him! Trying to win favor by entering the household while pregnant? She'll bring in a bedchamber maid first and have her give birth to the eldest son born of a concubine! And the Lin family, who think they're the legitimate main branch, have been living off her and using her money to handle everything. Now she'll make them pay it all back! - Sheng Yan never imagined that timid Lin Ruotang could grow claws. He only demoted her from wife to concubine, and she immediately demanded a divorce! Does she think she can stand up to him just because she's spread her business across Shengjing? She's a lowborn daughter of a concubine. Without the marquis's household to rely on, how could she manage such a vast enterprise? He'll wait for her to come begging! - Xie Mo, the jade-faced King of Hell, is the feared chief of the Inspectorate. Everyone in the capital knows that offending him is worse than offending the King of Hell himself. And yet he grants every request from the madam of the Sheng household, and always follows through.
