Overview
A suspect evaporated strangely in the detention compartment of Dongcheng Police Station. Agent "Mozi" (played by Gu Tianle) worked hard to arrest and search, but there were still no clues and clues. When he was puzzled, Mozi received incredible news that the fugitive was exposed in the archives of the police headquarters in the city. In the anti-locked warehouse, the hidden criminal was shot in the chest and killed on the spot. How on earth did he escape from the East City cell, sneak into the archives of the headquarters, and get from one "secret room" to another "secret room"? Headquarters experts confirmed that 9,999 bullets were killed, originating from Mozi's police gun, so he became the biggest suspect. The cause of death of the lurking criminal is treacherous, and the background is complicated. Mozi was complicated by fate, and it was difficult for me to distinguish between hot and strange cases when facing the enemy.
