Exploring Again

After lights out, outside Room 23 in Zone C.

Shang Jianyao and Long Yuehong—who were wrapped in thick, military-green cotton coats—met up and shone their flashlights at the brownish-red wooden door with white numbers.

"Are we really going to give it a try?" Long Yuehong was still a little timid now that they were going ahead with the plan.

Shang Jianyao took out an electronic card with his other hand and calmly said, "Pay attention to my condition. If anything goes wrong, shout immediately."

"Shout?" Long Yuehong subconsciously asked. Wake him up?

Shang Jianyao held the door handle with the flashlight and replied seriously, "Shout for help."

Long Yuehong was speechless. He then took a deep breath and got his lungs ready, prepared to shout at any moment.

Shang Jianyao gently pried open the lock and slowly turned the doorknob. He pushed the door forward bit by bit as if it weighed more than 500 kilograms.
