Those who wonder why the inside of an ice hut does not melt when you make a fire fundamentally lack understanding of the concept of cold.
Most people find it hard to comprehend how one can still freeze to death indoors in winter even when the air conditioner is set to maximum heat and full power.
But many people from the north can understand.
If modern heating with air conditioning can't achieve it, how could a fire meant to warm just one person possibly do so?
"Ice has excellent insulation properties. The outside and inside are two completely different temperatures, so the inner layer of ice and snow will indeed melt a layer. But with the subsequent rush of cold air, it will refreeze, turning into ice blocks. That's why lighting a bonfire in a cave will not only not melt the snow house, but it will actually make it harder,"
Bi Fang shivered and briefly explained before continuing to dig out snow.
