Qu Jianlei gave a rough explanation of how geothermal heat formed, but Hua Xiezhi was focused on something else.
"I understood... but where did you get all this knowledge?"
Qu Jianlei found that a little strange too. He knew information was monopolized in the Wasteland, but... did even this kind of information need to be kept hidden? "Isn't this something that's not too hard to learn?"
"It's very hard!" Hua Xiezhi answered without hesitation. "I've never heard anyone mention it."

For Qu Jianlei and Hua Xiezhi, this expedition had been more than worthwhile.
Geothermal heat saved a tremendous amount of energy, not to mention... they had the meat of more than a dozen Golden Apes to eat.
Still, the
