此文自动翻译Introduction:Because both the crystal earth and the earth are spherical, it is easy to be reminded that the crystal ball is clear and transparent, which is my ideal future world, so I drew this work. Crystal balls are divided into three layers: the first is where people live, the second is where cars can drive, and the third is nature, so that nature will not be polluted. The sky is blue in the crystal ball, the sea is blue, the air is fresh, there will be no haze, there will be no traffic jams, this is my ideal future undersea world.
