This cave is indeed the lair of the Ice Beasts. Along the way, they avoided many Ice Beasts. For those they couldn't avoid, Qi Buyu acted as bait while Shen Wu and Wen Ran silently slipped behind the Ice Beasts and resolved them quietly.
Qi Buyu didn't know why he became the bait, but somehow, in inexplicable circumstances, he became the one doing the dirty and tiring work.
Qi Buyu had his opinions, but every time Shen Wu shared something enthusiastically with Wen Ran, Qi Buyu's opinions vanished. Yes, he was very self-sacrificing.
By the time they reached the deepest part of the cave, Qi Buyu looked as if he had been pulled out from a pile of trash. In contrast, the other two, Shen Wu was still in spotless white clothing, and Wen Ran's pink dress remained clean.
They really seemed like they were on a trip.
The deepest part of the cave was an open area where you could see white eggs everywhere. These eggs were large, reaching up to a person's knee.
