Myth Rebooted: Dimension Arrival

My name is Zhang Jian, and the environment I am in at the moment is very strange. I am probably in the same place I was in my own home 20 years ago, around 2003. At first I didn't notice anything unusual and thought someone was playing a joke on me. Until I accidentally looked out the window. Only then did I realize that an office building that was supposed to stand in front of my home had disappeared, and was replaced by a small pond that should have disappeared long ago. In addition to the difference in time, I also found that I seemed to be the only one here. This may sound strange. When I go out to search these days, I always find nothing and no one around. But after night falls, I can always vaguely hear strange chattering sounds like human speech. What's even more strange is that the buildings and trees around my house are showing a crumbling decline. There is a grain station not far away, and a vegetable market where the food is always fresh even though there is no one around. After these few days of exploration, I have to believe that this is not my original world. I should have come to a different world. This novel and its characters are purely fictitious.
