Drift Building

The old era collapsed and the laws of physics were distorted. After the "red rain" falls, urban buildings collectively wake up and turn into "building monsters" of various shapes. They follow some ancient call and form a huge migratory torrent heading west. The surface of the earth is divided into eighteen "divine punishment areas" full of Cthulhu-style pollution. Only by passing the trial of the "Drifting Building" can one reach the ultimate temple.
