Background: The earth’s environment is getting worse and worse, and extreme weather is becoming more and more serious. Hot weather can be as high as 50 degrees Celsius, and cold weather can be as low as minus 50 degrees. Humans have built a protective shield in response to extreme weather, using technological thermostats to control the temperature for human survival. However, the area and resources of the constant temperature protection shield are limited. Only the rich and powerful people on the earth have priority to enter. The rest can only draw lots randomly. Some are given one place per family, and some are given three places per family. Unlucky families Not even a chance to get into the thermostatic shield.

Player: The player is the young and promising village chief of Snow Mountain Village. Since the snow-capped mountains are far away from the city, there are very few opportunities for people to enter the protective shield. There is only one quota for their entire village. Everyone thinks that the village chief should be the most qualified to enter the thermostatic protective cover. But the village chief was unwilling to enter the thermostatic protective enclosure alone. He wanted to give the opportunity to his children. They have survived a spring and autumn, and many people have died this year. I wonder if everyone can survive this cold winter. There are not many animals left on the earth.
