During the Yuanhe period of Xianzong (806-820 AD). Reason for selection: After the Anshi Rebellion, the Tang Dynasty turned from prosperity to decline but was striving for a complex period of resurgence. The separatist rule of vassal towns, the exclusive power of eunuchs, fierce party disputes, and sharp social conflicts provide rich soil for various cases, and may collide with the protagonist's modern concept of "Zhongxing". Shen Mo (modern name: Lin Mo) was a senior front-line criminal police officer who died in the line of duty and traveled through time. The soul travels to Shen Mo, a young detective from Wannian County (the eastern half of Chang'an City) who just died due to an "accident" while investigating a case. Solve the bizarre and intricate unsolved cases in Chang'an City. The conflict and integration of modern legal concepts, criminal investigation technology, the social system of the Tang Dynasty, and the world's sophistication; the protagonist's personal identity and struggle to integrate into the times; the insignificance and persistence of trying to single-handedly leave a "mud claw" mark in the torrent of history.
