American Detective: Unlock Detective Dee from the Beginning

On the first day after traveling to the world of American TV series, Lin Yan awakened the god-level system. "The Memory Archives can unlock the abilities of all domestic detectives such as Di Renjie, Song Ci, and Yan Shuangying." Before I could be happy, the system popped up: "Insufficient energy and will go into sleep soon. It can be recharged only after solving the case." Lin Yan looked at his new body - 22 years old, he had just joined the LAPD for three months, and he was not even familiar with a gun. And his first case: a secret room shooting, with zero physical evidence, and the whole team was helpless. He took a deep breath and opened the only function in the system that was still available - the deduction platform. Di Renjie, lend me some brains.
