Lin Wu even saw two groups of survivors armed with various melee weapons facing off in a grain and oil shop on the business street. Lin Wu didn't want to stir up trouble, so he walked on the other side of the street, and moved forward relying on trees or cars to avoid getting shot. Even if the others didn't have guns, they might have bows and arrows or the like.
