Xie Zhiwei, the son of the former minister of Dali Temple, was wronged and executed by his entire family. He was judged not to live to be twenty because of his frailty. However, he escaped death by luck and became a sickly invalid in the eyes of the world. In order to protect himself and overturn the case, he was forced to marry Gu Lin, the ruthless Marquis of Jingan, who was in charge of the royal secret agency "Xuanjing Division" and became his "happy" wife. On the wedding night, a bizarre murder occurred in the Hou Mansion, and all clues pointed to no solution. Under everyone's surprised gazes, Xie Zhiwei relied on his extraordinary powers of observation and rigorous logical reasoning to point out the real murderer in an understatement on the sick bed, making him a blockbuster. From then on, a sick beauty in a wheelchair and a cold-faced "King of Hell" Hou Ye formed the most incredible detective team in Daliang. From the headless bride in the secluded house in the capital, to the secrets of the painted skin in the Jiangnan water town, to the sudden death of the general at the border fortress... In the process of solving each strange case, the two of them went from being testy and tit-for-tat rivals to becoming the only confidants who can hold their backs. Xie Zhiwei's "illness" is a disguise, and Gu Lin's "coldness" is a mask. The shocking conspiracy that destroyed the Xie family many years ago and the undercurrent in the court are once again surging. The two of them join forces, using each case as a knife to cut through the hypocrisy and use their bodies as bait to find out the mastermind behind the scenes. In the end, the injustice is avenged and the world is cleared.
