I'm Twinned with a Scumbag. When I Become a General, He Eats the Chaff.

[The heroine has a double life with a scumbag boy + a strong woman + a career + abusing the scumbag and getting slapped in the face] In her previous life, Lin Yi, who was born into a general family, worked hard to support her husband-in-law, from an unknown student from a poor family to a powerful first minister. However, Pei Yanchu once had a brilliant career. He took off his disguise and took advantage of General Lin's death in battle to kill his wife at the hands of robbers, then turned around and married his childhood sweetheart Bai Yueguang. On the wedding night, Lin Yi, who faked his own death and lurked in the house, sent Zha Fu and Qingmei to hell. —— But she didn't expect that she and the scumbag husband were both reborn on the day they first met. In this life, Lin Yi turned to support his cousin, vowing to completely crush Pei Yanchu's dream of being the chief assistant. Later, he joined the military camp, studied military strategies, and diligently practiced the skills of killing enemies, just to protect his family and the country. Pei Yanchu, on the other hand, firmly believed that without Lin Yi in this life, he would still be able to take the position of chief minister, and married his childhood sweetheart without hesitation. Unexpectedly, his career was smooth sailing in his previous life. In this life, his official career was repeatedly hindered, and he could not even pass the imperial examination. Bai Yueguang, who had been steadfast to him in his previous life, also tore off his mask, abandoned him in pursuit of glory and wealth, and switched to the arms of others. In the end, Pei Yanchu, who was completely defeated, suddenly realized how important he had missed. He knelt in front of her: "Yiyi, I was wrong. I am willing to spend the rest of my life to atone for my sins. I just ask you to give me another chance." Lin Yi smiled coldly: "I have already given you the opportunity in my previous life. In this life, you only deserve to atone for your sins!"
