In the misty rain in the south of the Yangtze River, Jiang Yan, a folding fan strategist, Li Zhao, a cold-faced swordsman, Xiao Man, a smart girl, and Pei Ye, a wild swordsman, meet unexpectedly due to a bizarre murder case. The four of them formed a team by mistake to investigate the case. His reputation spread throughout the world.
After that, the four-person team traveled all over the country and embarked on a journey of investigation. Every life and death battle makes their friendship deeper and deeper. They trusted each other in sword fights, supported each other in the bloody storm, and became legends among people in the world of punishing evil and promoting good.
However, there is a turbulent undercurrent behind the calm. As the ancient monster beast reappeared in the world, the foursome died and dispersed. The four people who once laughed proudly side by side finally parted ways, leaving only a glorious and sad legend that gradually faded over the years and became a sigh after dinner among the people in the world.
Purpose: growth, friendship
