Wen Lai was a Sixth Rank Esper, but his ability was not water-based, so he still needed an oxygen tank to breathe underwater.
Almost all the explorers were the same, and they communicated through electronic devices.
The moment they heard their captain Wen Lai's words, the other three squad members erupted.
"What? More than twenty Energy Stones?"
"Holy shit, Captain, you're amazing! You actually found twenty Energy Stones in one go!"
"Hahaha, looks like we'll each pocket another four or five Energy Stones!"
Two or three months had already passed since Viteo sent people to begin exploring this underground river.
Starting from the lake above, they had surveyed almost the entire downstream stretch of the underground river, all the way to its outlet into the Pacific Ocean.
In fact, the river's current had washed most of the Energy Stones into its lower stretches.
As for the upstream section, where they had to travel against the current, they had only explored ten to twenty li so far.
There was no helping it. Viteo's explorers followed the Energy Stones, burrowing wherever they found the most.
Wen Lai's squad was small. As the Energy Stones they found downstream grew fewer and fewer, they decided to begin exploring upstream.
Some others had the same idea as Wen Lai's squad.
