After reaching the cave entrance, Ye Chen could clearly feel a breeze blowing out from inside. When he pushed with his hand, it seemed as though a stream of air was pushing against him.
If he didn't apply force, his hand would likely be pushed back out by the air pressure at the entrance.
"So, Ye Chen, what's the situation down there now?"
Anying and Lin Yaru watched anxiously. Ye Chen descended to the cave entrance and seemed to stop suddenly at the exit, so they didn't know exactly what was happening on his side.
"Nothing unusual. Just like you said, there's a pressure difference inside the cave. The pressure pushes all the mud outwards. I just tested it with my hand, and even if we want to go in, we'll need to apply some force to squeeze through this spot."
