Ye Yuan considered the feasibility of the plan Xu Hang had proposed.
Although these lifeboats were only the size of an oil drum when compressed.
Even so.
Sending dozens of such lifeboats into the underground river through that sinkhole would not be a simple undertaking.
After all, the sinkhole's depth was right there. Even for Xu Hang and his people, it presented a certain degree of difficulty.
Otherwise, those geographers would not have abandoned their research into the underground river because of the sinkhole's depth.
Naturally, other factors were involved as well.
But the main issue was still that the sinkhole was too deep, making it inconvenient to transport much of the equipment down.
If that sinkhole had only been a few dozen meters deep, would you believe that underground river might already have been developed into a tourist attraction?
"I'll think of a way around that. As long as we can confirm that our method will work, that's enough."
Xu Hang saw the hesitant expression on Ye Yuan's face.
He knew what Ye Yuan was worried about.
But what worried Ye Yuan was nothing to Xu Hang.
Just now, after Ye Yuan had given a clear answer that it was feasible to approach those mutant beasts through the underground river, Xu Hang had made up his mind.
Not only did he intend to transport the lifeboats down through that sinkhole.
If possible, he also wanted to take control of that underground karst cave.
After all, it was a massive natural underground cavern.
Was there any place more suitable for conducting certain secret research?
So, if he had to choose between expanding the cave entrance and making a rapid descent through the sinkhole.
He would naturally choose the latter.
Not only would the latter save time, it would also avoid
