An axe...
Xu Xin breathed a slight sigh of relief.
It didn't sound like a particularly powerful weapon.
"The mutant humans I saw in the underground city bear a strong resemblance to the appearance you just described."
He had previously told Ji Chaoyang about his experiences in the underground city, and Ji Chaoyang was aware that he had seen mutant humans there.
Ji Chaoyang remained silent for quite a while, contemplating something.
Xu Xin did not speak either, as he was also pondering how to survive the impending disaster.
After dozens of seconds, Ji Chaoyang spoke.
"Xu Xin, I'm afraid we're going to have to engage in a defensive battle," Ji Chaoyang's voice became somewhat lower, "In the icy cold, with outside temperatures at least tens of degrees below zero, most survivors wouldn't have the ability to go out. If these mutant creatures attack the treehouses, the survivors will have to defend themselves inside."
