after walking around, an xiaowan couldn't help but sigh at the "sky" and the weather system.
this was probably the first time that humans had successfully migrated underground.
this place was not as damp and cold as a basement. instead, it was as warm as spring all year round. he wondered how much energy these things consumed every day.
" there are countless solar panels outside. we've seen them along the way. " Huo Shen seemed to have seen through an Xiaowan's thoughts and suddenly said.
an xiaowan reacted and immediately nodded.
"So that's what the solar panels are for!" she took a deep breath and couldn't help but widen her eyes and sigh, " "in that case, all the equipment here might be powered by solar energy. I don't need any support at all. It's so environmentally friendly."
Huo Shen nodded slightly and squinted his eyes.
