Indeed, as you suggested, Wei Yingyue carefully explored the area and soon expressed joy in her voice: "There really is a crack, but it's not very large, just enough for a fist to go through.
You listened and deliberately shifted your body, causing some debris on your back to rustle and fall.
Wei Yingyue was startled and quickly looked at you, asking, "What happened to you?"
"It's nothing, I'm just trying to find a way out. If we wait for those above to dig here, it might be too late. At this point, self-rescue is necessary."
Upon hearing this, Wei Yingyue quickly squatted up and reached out to move some debris from behind you.
"Wait, don't do that!" You hurriedly said.
Wei Yingyue looked at you; in the darkness, they seemed only able to make out each other's eyes and facial outlines: "Tell me what to do."
"Squat at the position of my abdomen. This way, when I shift my body, the small debris won't hurt you."
