Klein Cube

They say that a cube has only six faces, eight vertices, and twelve edges. Maybe we can survive just by getting past these copies. But when someone gets the real face and asks this question, there is only a cube on it that is no different from the one in the math book. When the past and future no longer exist, and only the present exists forever, where will you go? -------------------------------------------------- Li Jinyan is a very strict person. If someone suddenly told her that the world was going to explode, she would never believe it. Unless she really saw the small apartment she had lived in for more than a year slowly falling upside down, and she and the person next to her both had the same cube tattoo. She thought maybe it was time to go crazy. She opened her mouth and saw the world making way for her words.
