Su Huai, the real young master of the Hou Mansion who had been mistakenly replaced for seventeen years, returned from the border town surrounded by mountains of corpses and seas of blood. He thought he could regain family ties, but found that his biological parents and elder brother only preferred the scheming fake young master who occupied his identity. They treated him with indifference and contempt, and regarded him as a stain on his reputation. Su Huai did not beg or entangle. After seeing everything clearly, he resolutely established himself as a widower and severed ties with the Hou Mansion. Relying on his superb autopsy skills, he repeatedly solved strange cases, step by step from the bottom of Kyoto to the top of power, making the entire Hou family regretful for what he had done. In the process, he met Xiao Changyuan, the Prince of Jing who was also trapped in the quagmire and disguised himself as cold. The two souls abandoned by the world attracted each other, redeemed each other, and finally joined hands to overlook the mountains and rivers thousands of miles away.
