The original teacher of the police academy, Field Field Marshal was transferred to be a spy. He was sent to the prison to approach a man called Nie Fengyu. Not long after entering the prison, they found Nie Feng Yu. The battle field was getting closer and closer. As time went by, they were even attracted by Nie Feng Yu. However, Su He, the current warden and former classmate of Yuanye, warned him not to cause any trouble for Nie Fengyu. The mission went smoothly, but Zhan Ye never thought that Nie Feng Yu only treated him as a plaything. From the very beginning, his mission failed, and it wasn't just the mission that failed. However, when Nie Fengyu escaped from prison, he still brought Yuanye with him. However, right in front of everyone's eyes, Yuanye chose to leave him and walked towards the police on the other side. After failing the undercover mission, Field was transferred to a remote police station. Including him, there were only four people who met Qian Ye there. As for his new place, his new colleague, Zhan Ye, he had originally thought that he could start over there, but now, Nie Fengyu had appeared in front of him. Furthermore, this place wasn't unfamiliar to him … Only then did Field learn that he had not left the "prison."
