Xia Xiao dealt with stones every day, taking various kinds of stones into the space. Shitou had not woken up yet, and Zha Xiao was somewhat worried, even wondering if only an energy stone could awaken Shitou.
Upon bringing it into the space, Xia Xiao placed it beside Shitou, not knowing whether it would be of any use. Xia Xiao observed for a moment but couldn't discern anything; she didn't even know how Shitou absorbed energy.
However, when Xia Xiao was about to leave the space, Shitou spoke up, "Energy stone, where did you get this?"
"I found it by accident and brought it here, not sure if it's what you need."
As soon as Xia Xiao finished, Shitou said, "It's exactly this kind."
Shitou was extremely happy, "It's just that there's not much energy inside it."
"I've now joined the Geological Department, and the kids are older, so I can go out and do research with them. You don't need to sleep anymore, right? Come with me," Xia Xiao suggested.
