Xiaomei's Antarctic expedition team froze itself without receiving any materials. In the meantime, someone else's freezer ran out of power, which was actually Xiaomei's last one (CG said it had been an hour). After the overall power shortage, the base system moved all the remaining power to Xiaomei's freezer, so Xiaomei's freezer could still be maintained, and others' freezers could not work because of no power, resulting in death.
