The Idle Wife Is in Power

She was the little-known third lady of the Chenhou family in Jiangnan during the Jin Dynasty. He is also a famous mecha general from another time and space. She has no knowledge of common people's affairs, and she lacks everything in virtue, speech and merit. Her hobby is mechas and her hobby is fighting. She is the failure among noble girls and the unsupportable Adou among concubines. So what? She has a big brother who protects her. Everything is easy to discuss, as long as you don't bother. There is only one thing: she wants monogamy and will never compromise!
