Spring Return from Night Prison

It tells the story of Xia Limeng, a female beggar on the run who accidentally witnesses the assassination of Shuoting Proton. Because she looks similar to the deceased, she is forced by Gu Changfeng, the leader of the bad guys in Dayong, to replace the proton to avoid war between the two countries. During the day, she pretended to be a sick and foreign hostage, dealing with envoys, officials and assassins; at night, she was bound to the "Night Prison Bad Person System" to investigate cases, perform autopsies, and track down the real murderer. In order to survive, she gradually gathered the low-level informants, established a dark night intelligence network, uncovered the war conspiracy behind the proton case, and moved from being a chess piece living for others to using her own name to control her destiny.
