The Four Pillars

Zhao Mangshan, Xu Shuiwan, Wu Mian, and Wang Maiyan graduated from Jinxi University. After failing their job interviews, they were assigned to the narcotics squad led by Chen Weihua at the Public Security Bureau in Bingji City.

During a raid on drug dealers, Zhao Mangshan and Xu Shuiwan worked in perfect sync to intercept a fleeing vehicle. While undercover, Wu Mian and Wang Maiyan used their wits to stay in control of the situation and successfully close the net. Faced with a major cross-border case, the four worked with police from other regions. Zhao Mangshan and Xu Shuiwan went undercover, while Wu Mian and Wang Maiyan gathered intelligence, bringing down the drug-trafficking network.

They became the backbone of the frontline narcotics unit, earning the new generation the title of the "Four Pillars."
