Arctic Circle.
Right now, Lu Zhou is in a research laboratory inspecting a stone. If Chu Zixuan was here, he would instantly recognize the stone to be similar to the one he'd seen in Sky Stone Village!
He was rather content at the moment, with physicists, biologists, historians, and chemists all gathered here. In the past, humans weren't this unified; even deciding on a collaborative project required assessing its pros and cons...
Shortly after, experts of various disciplines began inspecting the stone with their knowledge and techniques.
Once their examinations were finished, Lu Zhou quickly asked, "What is this?"
The archaeologist started, "Based on the stratigraphy, this stone first appeared on Earth around a million years ago..."
The other scholars agreed, "Indeed, this thing has been on Earth for about a million years!"
Lu Zhou frowned and said, "So you're saying that this stone isn't a product of Earth?"
"Correct!"
