The so-called banding together for warmth is nothing more than leveraging each other's strength; having people around can at least make evildoers less brazen, somewhat wary.
As for hoping to get help from neighbors, that's too naive.
The cultivation world is unknown in terms of cause and effect; without significant profit involved, regular cultivators won't get embroiled in disputes for no reason.
Of course, this refers to regular cultivators; as for the unpredictable evil cultivators, they are a different matter.
Moreover, banding together only mitigates risks with no strong intent; it can't truly make one completely safe.
For instance, the infamous Evil Thief Gang in the swamp might avoid houses with many residents when choosing targets aimlessly.
However, if they have a strong purpose and come specifically for you, it can't be avoided; at most, it makes them expend more effort, Restriction Talismans, or Array materials.
Therefore, safety ultimately relies on oneself.
