I am an ordinary meteorologist who predicted in advance that an extreme weather doomsday would erupt in thirty days, yet I was mocked by my entire family. Resolutely quitting my job and selling all my assets, I joined hands with my friend Xu Nian to renovate a house, madly hoard supplies, and build a safe refuge. Alternating extreme heat and bitter cold swept across the globe, the city fell, and the relatives who once sneered at me begged on their knees for the door to be opened in minus forty-degree wind and snow. I set rules to take them in, and relying on precise meteorological predictions, I led everyone to seize the safety window period to scavenge for supplies and resolve the survival crisis. With underestimated professional knowledge, I guarded vitality in the doomsday, led survivors out of desperation, and rewrote fate.
