I'm a Policeman, but I'm Given the Skills of the Underworld

Lin Yun traveled through the world of film and television and became a policeman. Bound with a god-level capture system. Catching criminals earns points. If you successfully capture a Class A wanted criminal, you will also receive additional rewards. With double protection, Lin Yun felt stable. Unexpectedly, the system's rewards made Lin Yun dumbfounded. Reward 1: Iron marbles are comparable to flying knives, with perfect hits Reward 2: The two golden fingers can be used to explore hills and caves, which is extremely powerful. Bonus 3: Shrinking your bones and disguising yourself can fool facial recognition technology These skill rewards are not available to Lin Yun. These are all the old nine skills. I'm a police officer, not a grave robber. What I need is criminal investigation and firearms skills. But Lin Yun later discovered that this world was not an ordinary world. In this world, tomb robbing cases occur frequently, and all kinds of strange cases emerge one after another. Old Nine Skills... This novel and its characters are purely fictitious.
