Lin Yan, 26 years old, was the youngest head of the serious crime team of the Nanjiang City Criminal Investigation Detachment. He was professional and sharp, but while hunting down a serial murderer, he lost consciousness in a sudden explosion.
When she opened her eyes again, she was lying in a bumpy carriage, wearing coarse linen clothes, and beside her was a wailing maid. The original owner was Shen Yinghe, the daughter of the magistrate of Linshui County. She was plotted against because of her father's investigation, and she managed to escape before being killed by her enemies. She was on the run. The real cause of death of the original owner was excessive fear - that is to say, when Lin Yan traveled through time, the owner of this body was already scared to death.
Lin Yan spent three days digesting the reality and another three days to figure out the situation. She didn't have any golden fingers, no system, and no space. The only thing she brought with her was the criminal investigation thinking carved into her bones.
She made a decision: not to return to Beijing to visit relatives or to seek refuge in the countryside. Instead, she took on Shen Yinghe's identity and returned to Linshui County to find out who the case files in Father Shen's hands pointed to.
This is where the core conflict of the story unfolds - a modern criminal policeman who believes in evidence, logic and procedural justice is thrown into an ancient officialdom where power is supreme, torture is the rule, and human lives are as little as trivial.
Linshui County is peaceful on the surface, but in fact there are turbulent undercurrents. The half-volume account book left by Shen's father was not involved in an ordinary murder case, but a private salt smuggling network involving the county magistrate, county magistrate, local gentry and even state officials. More importantly, the end of this network faintly points to the capital.
Lin Yan has no official position, no real power, and even basic personal safety is a problem. All she can use is her own brain - the logic of on-site investigation...
