Yu Xiao Qian

In the legendary Nine Cities, Fan Yun, a fallen noblewoman, crosses paths with Qi Zheng, the cunning and ambitious city lord. What begins as suspicion soon turns into an alliance as they navigate power struggles, hidden schemes, and shifting loyalties. Together, they must face challenges that test their convictions and discover trust, friendship, and love along the way.

New SWAT instructor Tan Yan and Captain Liao Bu Fan, who had difficulty cooperating, gradually become united in their thinking. The SWAT team also gets better and better under their leadership. Tan Yan mistakenly became a "hero" in a case, gave up his "honor" after discovering the truth, and successfully completed the task of the "Hidden Front" plan.
