A major disaster in 2248 caused the world's civilization to basically disappear. The world's environment was severely polluted, sea levels rose, and the continental plates deconstructed one after another and collided again to form three new continents. The world's population plummeted, and all of them concentrated in the underground world near Mount Kailash to avoid disaster. This hiding place lasted for 700 years, which is known as the "Ark Age" in history. During this period, all humans unified their language and only used "Ancient Chinese Language". After another 1100 years, that is, 1800 years after the cataclysm, mankind ushered in a new era. This is the era of the "Arena of Glory", where the arena replaces war, and gladiators replace warriors.
