During the third year of the Sui Dynasty, Emperor Yan Jian founded Jiejianfu, a spy agency to aid in his military campaigns. A caravan carrying tribute from Yutian was attacked and destroyed on a snowy night. Feng Xiao, a high-ranking officer at Jiejianfu, was dispatched to look into the incident. In Liugong Town, he encountered Cui Buqu, an agent from Zuoyueju, who was also there for his own assignment. Initially at odds, the two agents clashed in a contest of intellect before realizing their cases were connected by a shared adversary. Their collaboration uncovered the existence of a vast organization known as Yunhai Shisanlou.
