A real disaster
Ren Xiaosu once posed a question while chatting with Yan Liuyuan. What would happen if the walls that protected the humans collapsed?
At the time, Ren Xiaosu didn't really pay much attention even though he was the one who raised the question. After all, they would just rebuild the walls if they collapsed. The important people in the stronghold would still be important, and the refugees in town would still remain refugees.
But it was different this time. The walls could collapse at any other time but now. There were wolves waiting outside of the walls; wild animals and poisonous insects were also escaping out of the Jing Mountain range. There were face bugs and the Experimentals!
The tectonic plate movement that caused the earthquake was like a black swan that flapped its wings and brought a disaster upon the stronghold.
