Xu Xin said to Xu Ying, who seemed lost in thought, "I say, you took Wenxi down there, didn't she end up not being much help? From the looks of her energy, it's like she's been idle for a long time."
"Huh? Who said that!" Xu Ying snapped back, displeased, "Even though the underground human base can't manufacture weapons at the moment, we can still mine for minerals. Sister-in-law discovered many mineral sites down there and even helped modify the mining machines and tools, greatly increasing mining efficiency!"
"...Wenxi can modify mining machines?"
"Of course, you didn't think Sister-in-law's abilities were limited to making handheld mining picks, did you?" Xu Ying tapped her own head, "That's a capability we developed standing on the shoulders of alien technology. It can't be that shabby!"
"True. But, with that being said..." Xu Xin looked at her with some surprise, "Does this mean... you've already gained control over the underground world's power?"
