At 10:15 in the morning, Song Cheng once again arrived at the containment zone holding high-risk prisoners.
The pure white, undecorated corridor stretched out in view, with bright lights evenly spread from the ceiling. At intervals along the corridor, dark red lights embedded in the walls, ceiling, and floor could be seen. Armed guards, fully equipped, vigilantly stood guard at the T-junctions at both ends of the corridor, and numerous sensors, monitors, and sentinel weapons were hidden within the ceiling's security modules.
Every few meters along the corridor, there were heavy gates. Some of these gates had green lights above them, while others displayed glaring red lights.
