Xu Xin pointed to the Crystal House beside him: "The Crystal House is indestructible, you can hide in there."
Everyone nodded very seriously.
"Got it, Brother Xin!"
"Understood, I'll tell the others!"
Xu Xin nodded, turned around, and walked back.
The defense line for this group of survivors is to use treehouse crossbows to cover the beast horde with firepower.
Enough to scatter the beast horde.
As for after the exploding crossbow bolts are used up, their own combat power is not strong, there's no need to take risks.
Behind him, discussions from the survivors could be heard.
"The Crystal House is actually indestructible!"
"Yeah, I heard that even the big shots' purple-grade steel weapons got dulled, and didn't damage the Crystal House one bit."
"So strong?! Then we can make the Crystal House a fortress..."
"Can't do that, the treehouse heavy crossbows need to be installed on treehouses."
