Although most of the world has become a zombie heaven, there are still some people who have survived due to luck or other reasons, just like these students, and have built their own shelters.
Duanmu Huai's choice is simple — you stockpile food, I stockpile guns, and everyone has a bright future.
Instead of rescuing survivors everywhere, why not just take over the shelters directly?
Compared to a few stray ones like Xiao Mao, aren't the survivors in the shelters more numerous?
As for whether the other side is willing or not? That's not Duanmu Huai's concern.
The Tribunal is not some sentimental charity organization.
That's just how Duanmu Huai thought, and afterward, the Tribunal took in several waves of survivors. From them, Duanmu Huai learned that the city is indeed not completely overrun, and there are a few shelters, including one set up by the municipal government. So without saying a word, Duanmu Huai led a team to requisition them on the spot.
