Different from "the sky is distant and the land is also distant, and the agricultural machinery can run", the high-rise buildings for planting can be used everywhere, and the sloping fields that are not suitable for terraced fields can also be used as long as the water pressure can be pressed. Two or three acres of flat land can be used to build buildings, and tall buildings can also be built in the forest. Agricultural machinery pays attention to "vastness and flatness", while as long as high-rise buildings can jump up and the water pressure can keep up. One stresses horizontal and the other stresses vertical, which is easier to achieve? It would be a miracle if a tall building with the same or similar planting area as the existing farmland could be built outside the existing farmland!
