TRITENT Ⅱ

In the plot, while investigating a pyramid scheme, Cui Tiejun, Xu Guozhu, and Pan Jianghai discover that a key suspect is linked to a murder case from twenty years ago. To thoroughly investigate this case, the three veteran officers establish the Trident Working Group with the support of Director Guo. With the assistance of their apprentice Xiao Lü and young police officer Xu Man, the Trident Working Group successfully aids various police units in solving multiple major cases, ultimately revealing the truth behind the twenty-year-old mystery.

As the investigation deepens, the Trident team finds that all clues lead to a criminal organization called "Qingshan Society," which attempts to monopolize the market through a virtual currency known as "Yunmaobi." The Trident team faces numerous challenges and ultimately eradicates this criminal organization that has plagued Ping'an Province for years, successfully capturing the main perpetrator, Zhou Mao. Once again, the Trident protects the lives and property of the people in Ping'an.
