The world was not like this. Deep in people's vague collective memories, there are residual images of the "old era": the steel city pierces the clouds, the invisible network connects everything, and the brilliance of knowledge and order seems to be eternal. However, everything ended in the "Great Fall" - it was not a meteorite impact or a virus leak, but a more profound and indescribable "rule distortion". The sky tore, casting strange colors that were not the light of the sun and moon; the earth surged, growing strange structures that violated the principles of geometry. Physical constants have partially failed, common sense logic has become fragmented, and most of the ancient civilization's creations have become twisted ruins, or "relics" that contain dangers and opportunities.
