In a distant place, there is snow all year round, no one, no grass trees. There are just a group of holy elves. They look strange. They have no splendor in the snow. Their two black toes walk very fast. Their eyes have no color, and you will find that these strange little guys hide their eyes when their pupils contract. They feed by looking for creatures in ice caves. When they are quiet, their eyes are like frosted glass, which will only make people feel like two bright spots on their bodies, without any temperature. Only when you exercise, will ripples appear from the depths of the pupil and pass the whole eyeball from the inside out. Of course, I don't know about life on any planet.
