He was once the "blood wolf" who intimidated foreign countries and was an immortal legend in the field of special warfare. Nowadays, he is just an unknown security guard in a middle school in a small town on the southwest border, trying to bury the past in the ordinary and heal the scars in silence. However, when the top international mercenary forces invaded brazenly, put all the teachers and students of the school at gunpoint, and issued cruel provocations through global live broadcast, he closed the door of the security room and took out the dusty tactical box. The legend was forced to wake up, and the blade was unsheathed again. This is not a rescue, but his announcement to the entire dark world - the return of the king.
