After Chongxi Entered the House, I Became the Prince's Sword

The day Shen Yanci was sent to the Zhenbei Hou Mansion, everyone in the capital was waiting to see the joke. After a sinful minister, a sick and frail prince, no matter how you look at it, it is a short-lived marriage that only brings happiness and prevents disaster. But no one knew that on their wedding night, Shen Yanci discovered—— The prince Pei Xingzhao, who was rumored to be too ill to get out of bed, was not a cripple at all. He didn't marry him for happiness, But to borrow his knife to open up old cases that had been buried for many years in the back house of the Hou Mansion. The death of the late wife, the seizure of power by the second wife, the old accounts of the border army, the mystery of the salt case, the extermination of the old clan... After uncovering one thing after another, Shen Yanci realized that he had never fallen into the game by mistake, but had been in it from the beginning. At first they used each other to test each other. Later, he became the only one who dared to give his back to the other party in this deadlock.
