After discovering the body, everyone, led by Duanmu Huai, began... corpse scavenging.
That's right, this unlucky person evidently encountered some monster and was torn to pieces, with a large chunk bitten off. However, the issue isn't that; the problem is that the victim's equipment was... quite complete.
"The quality of the clothing is quite good."
Duanmu Huai glanced at the fragment of clothing in his hand and scanned it.
"It seems this group of underground people lived well."
"Is that so?"
"Of course, to be honest, I initially thought that in such an underground environment, it wouldn't be strange if they regressed to an era of primitive tribes wearing animal skins."
Duanmu Huai had quite a bit of experience with this; many Imperial relic planets were like this. Sophisticated technological civilizational ruins were inhabited by people living like primitive wild men... It is unclear how this cultural regression occurred.
