Chen Zhiyue felt a sharp pain in his head, and his consciousness was struggling in chaos. In a trance, countless images flashed through his mind like a revolving lantern, including bustling cities with tall buildings, disputes in the streets and alleys, and majestic figures in police uniforms. When he regained consciousness again, he found himself in a small and dark room, the air was filled with dampness, and a slightly yellowed 1977 calendar hung on the wall.
