The middle-aged man's name was Niu Yishou.
Niu Yishou had a characteristic: he always liked to hold back in his actions.
When he was young, Niu Yishou served in the military. He could have gone further during those years in the service, his rank could have been higher, but precisely because of his tendency to always hold back, he ended up being forcefully retired after saving something for himself during a mission.
After his retirement, Niu Yishou was directly assigned to Tianhai City. After more than a decade of struggle, he had finally become the chief of the police station.
After dismissing his subordinates, Niu Yishou directly pushed open the door to the interrogation room and walked in.
Upon entering the interrogation room, Niu Yishou was immediately surprised.
At this moment, Zhu Bufan was sitting leisurely in the interrogation room with his hands in his pockets, legs crossed arrogantly, showing no fear of whatever was outside.
