Weird and Immortal Log

A video captured the disappearance of my hometown village out of thin air. Rushing back overnight, I met a black figure walking upside down on the road. It climbed onto my car and into my shadow, which now has two heads. When I returned to the original site of the village - the village was gone and only a wasteland remained. But the lychee tree in the village is still there, and the dents in the bark that I stepped on when I was a child are still there. The villagers told me: Chenjiacun? Moved away a hundred years ago. So what have I been living for these twenty years?
