However, the long line of people was winding around the maze-like underground passage, while the surrounding light was getting dimmer and dimmer.
The carbon dioxide exhaled by hundreds and thousands of people froze the air, like a thousand-pound boulder pressing on everyone's heart.
Meng Chao became increasingly puzzled as he walked farther.
This did not seem to be the way out...
He had once sneaked into the underground passage.
Based on the flow of the air, as well as the aura from the end of the underground passage and the wilderness, he could determine the general direction of the exit.
The air in the passage before them was like a rotten swamp. It was completely frozen. He couldn't sense even the slightest ripple caused by the gentle breeze.
Sure enough, it did not take long for a large block to appear in front of them.
There was no way forward.
Other than where they came from, the other three walls were as hard as iron.
