Space Returns to Before the Doomsday

In 2040, after a blizzard that lasted for half a month, the earth was foggy all year round, natural disasters continued to occur, food production was greatly reduced, wild beasts were rampant, and the end of the world was coming. The city was the first place to suffer. Zhao Qian only lasted a year before starving to death. Unexpectedly, I discovered that I was reborn two years before the end of the world, and had a portable space. This time she must be fully prepared before the end comes and find a way out for herself and her family. She will do her best to protect those who love her. For those who hate her, don't blame her for not lending a helping hand. This article has a golden finger - the heroine will be extremely lucky. If you don't mind, don't enter. Ps: I've been watching a lot of disaster movies recently, and my imagination has been enlightened. I hope you all like them.
