Qingchuan County, a quiet small county on the southwest border of Dayin, was peacefully broken by a bizarre "corpse burning case in a theater." Yi Xiaoyao, the county police chief who was only sixteen years old, took charge of the case with his extraordinary talent and family skills.
During the investigation, he met the mysterious girl Su Qingyuan who was looking for her relatives. Later, best friend Shen Mo, Jianghu knight Xie Feng, Qingyuan's maid Wan Qing, and Liu Mansion's daughter Liu Yueyao joined one after another. Six boys and girls formed the "Youth Detective Team" and uncovered the conspiracy behind the case.
Since then, strange cases such as "strange diseases in fishing villages", "theft of ancient temples", and "murders with nursery rhymes" have followed one after another. Team members each perform their duties and work together in perfect harmony. When they solved the mystery, they found that these cases were related to the "Wei Party Unjust Case" many years ago.
As the investigation deepens, they not only have to face the murderer and complicated cases, but also deal with pressure from the local government and the court. The relationship between Yi Xiaoyao and Su Qingyuan also heated up while fighting side by side. They set out from Qingchuan and traveled to many places, eventually uncovering all the truth, bringing justice to those who had been wronged, and finding their own growth and destination.
