Earth Barn

(Die Jia Die Jia: The author's level is limited. Although it is said to be science fiction, many parts may be very silly and the descriptions are average, but it should still be readable) One year, the earth fell into despair due to overpopulation and environmental collapse. The food crisis has reached a critical point, traditional agricultural technology can no longer break through biological limits, and alien colonization is also impossible. In just a few decades, sea levels rose and the climate changed drastically. Humans were forced to retreat to a few high latitudes, and the population dropped sharply. Human beings will break through the difficulties of survival in a different way and witness their true universe in the long years.
