Reborn, I Have a Detective System

In his previous life, Shen Jiangheng died in the line of duty and was reborn to the day he just entered the police station. I unexpectedly discovered that it also had its own system, but what was both sad and happy was that the system was incomplete and needed to be constantly updated and improved by myself. Alas, well, in that case, let's see how he comes up with a new trick. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
