Original Ruins

The story was originally a reflection on the whereabouts of human civilization. It used the exploration of extraterrestrial planets by an advanced civilization of another type of earth planet (the Reborn people) as a metaphor for individual stages of the development of earth civilization. Through the strength of Reborn civilization in the face of lower civilizations and its weakness in the face of higher civilizations, humans are warned to face the universe with caution and cherish the earth's environment for survival.
