Actually, this should have been a foreseeable situation, with the sudden appearance of a large number of people in the wilderness, along with the constant nuclear radiation and seemingly permanent permafrost...
All the debuffs seem to have been collected, and it's normal for this world's harsh environment to cause large-scale famine in winter. And judging by their appearance, many people seem to have been hungry for a long time.
Yet, despite this, they don't look ugly like the starving and diseased people on Earth; instead, they all seem to have a "high attractiveness" filter, and the average attractiveness of the refugees in this post-apocalyptic nuclear winter world is surprisingly high.
This actually indicates that their level of evolution is quite advanced, at least in progressing to converge into a likeness of the "Venerable King," unlike in the Old Demon Emperor's world where everyone looks bizarre and grotesque.
