In the summer of Purple Star Calendar 3384, the Yincheng Criminal Investigation Bureau once again welcomed a group of young men who had just graduated from the police academy. What surprised the captain of the reconnaissance team, Zhou Long, was that he was not required to show up originally. He had always gone through a formal welcome ceremony, but was then called to hold an internal backbone meeting at short notice. He never thought that his fate would subtly change from here.

Strange events followed one after another, and they gradually realized that it was not just this city that was beginning to fall apart; and the clues traced back, eventually pointing to two words.
Concept: It's about two people who are both teammates and competitors.
