[Edge: Drug Enforcement Twins]

He is Lu Chenzhou, a top undercover soldier who once went deep into the drug den, but was labeled a "problem person" due to "violations". With unhealed scars and an incomprehensible past, he was transferred to the city's anti-drug detachment; he is Shen Zhiyan, a technical elite parachuted from the provincial department. He has repeatedly solved major cases with data traceability, but has never set foot on the real crime scene, and is regarded as a "keyboard warrior." With a single order, the sharpness of the practical school and the calmness of the technical school were forced to bind. The first partnership at a high-speed rail station went from tit-for-tat to unexpected complementarity - Lu Chenzhou used micro-expressions to identify drug dealers, Shen Zhiyan intercepted the contact person with data flow, and the three words "White Faced Buddha" suddenly burst out of the drug dealer's mouth, like a key, prying open the huge drug network hidden in the darkness of the city. A life-and-death anti-drug war, a road of redemption from confrontation to side by side, in the rain of bullets and the maze of data, the sharp edge will emerge, and the two will sharpen together.
