You're Not the One to Be an Undercover Agent.

Lin Yi was reborn, returning to the day when he first participated in Operation Spring Thunder ten years ago. Unlike the youthful mood when he just walked out of the police academy, the hatred in his eyes was well hidden. All the betrayals in the previous life came to mind one by one, as well as the familiar face when he was shot in the dark... The joy of the plot is non-toxic, and the audience will move on to the main text. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
