Police Academy Freshman: I Can See Crime Patterns

[Criminal investigation + hard-core crime solving + micro system + single female protagonist + logical reasoning + not brainless] On the day after the college entrance examination, Qin Shi had a problem with his eyes - he began to see strange lines on people's bodies. The system told him that it was called "sin pattern". It only appears in people who have sinned. But guilt marks are not evidence. It cannot be used to arrest people. Cannot be included in the file. It only tells him: There is something wrong with this man. As for what the problem is, how to investigate it, and how to prove it - it's all up to him. From the police academy to the grassroots police station, from third-tier cities to the Interpol headquarters, he relied on these eyes to enter one puzzle after another that others could not solve. Until he discovered that the person he respected the most also had a sin mark on the back of his hand. And behind that pattern of sin, it had been buried for thirty years.
