"What happens if this door closes?"
The four of them had not gone far. People tended to feel afraid when faced with the unknown.
They had to figure out how the door worked. If it suddenly closed and they could not get back, they would be in serious trouble.
Ke Meng looked back at the door. It stood in a dilapidated wooden hut, with four wooden posts supporting the structure.
Although the wood was rotten beyond recognition, it had to be highly resistant to poison to remain standing in a swamp like this.
Ke Meng walked around behind the door and looked inside the hut. There were only a few simple pieces of furniture. Two wooden walls had collapsed, and the ceiling was completely gone. If it rained, water would definitely pour in.
But when Ke Meng looked up, he saw a hazy gray mist hanging five meters above the ground, and immediately frowned.
The oppressive surroundings made him uncomfortable after all.
"We'll find out if we film it with a camera."
Ke Meng and the others waited for the cameras. There were industrially manufactured cameras, as well as special items capable of recording footage.
They started by recording a video with a camera, leaving Shirley in the swamp to hold it and film the front of the door.
Ke Meng and the others retreated through the door and shut it.
Once the doorway had gone pitch-black, Ke Meng waited five seconds, then pushed the door open and saw the green swamp again.
Shirley was still standing in the poisonous swamp. "The door is still here. I can feel it. It hasn't closed."
"Hmm." Ke Meng mulled it over. It was probably a matter of closing the door.
This door had not closed, so Ke Meng could push it open.
