The little girl had been keeping an eye on the pink mist all along.
It appeared in old miner Miles' records and was often accompanied by extremely high humidity and temperature, causing what should have been a cool, dry mine to have an extreme heat sensation of over 50℃.
But realistically, this is impossible unless the bottom of the mine leads to an underground magma lake; otherwise, the overall temperature here cannot exceed 45℃.
Therefore, a more reasonable explanation is that the so-called high temperature is also an illusion given by "it," a false neural sensation.
It is worth mentioning that the moment Yun You began to feel the high temperature was precisely an hour after her HazMat suit was breached by the first vengeful corpse and when her wound contacted the mist.
