The semicircular rock wall at the center suddenly began to rain down—oh, no, upon closer inspection it was not rain, but rather black characters that were as tiny as raindrops!
A bizarre scene appeared!
These little characters continued to fall like grains of rice, piling up incessantly. At first, they accumulated in the center of the space, but soon spread outwards.
"We can't go on like this; the space will be completely filled!" Cao Shan urgently shouted, "Let's get out of here, quickly leave this place!"
However, when Cao Shan turned and rushed towards the passage, he was horrified to discover that the passage had disappeared!
The rock wall was intact!
"What, what's going on!?"
Cao Shan kept slapping the rock wall, but even as his hands became painful from the hitting, the wall remained as it was.
"It's over, it's all over, we're done for, this thing is actually a trap!"
