Xiangxue came over when she heard that, looked at the material of the clothes, even reached out to touch it, then raised her head: "This isn't cotton cloth!"
"Yeah."
Ling Feng nodded: "And it's not chemical fiber either, it's a very special kind of material!"
"Could it be that these people came from some civilized world we don't know about yet?" Xiangxue asked.
"That should be it!"
Ling Feng nodded, narrowing his eyes: "The universe is so vast, there must be countless civilizations out there. Having their own unique technology is perfectly normal."
"Anyway, they came to Earth, and for some unknown reason had an internal falling-out, so they never made it back. They also left a huge number of Energy Blocks behind here, which led to what happened today, right?" Xiangxue asked.
Ling Feng nodded: "You're right, that's pretty much it!"
