Wen Lele conjectured, "Maybe they had already left using another route. After all, whoever comes here would have to come using the main route. Since someone has already gone inside, we might have made a wasted trip this time. But we can't be too sure either."
"If it were that easy to go in, would I have had to come a second time?"
"You have a point," said Wen Lele.
"Lele, wait above ground when we go inside later, alright?"
Wen Lele was obviously reluctant to do so. Thus, she said, "Let's go down together."
"If all of us go down together, how are we supposed to come out if someone fills the hole? It's better to be safe than sorry," said He Yi.
"There isn't a single soul in sight. Who's going to fill the hole? I must go in with you guys to get an eye-opener."
Seeing that there was no way to convince her, He Yi decided to give in and allow her to go in with them.
