Prehistoric Battle Royale

The Amodo Protoss descended and the earth fell into an apocalyptic crisis. Humanity is forced into a game called [Prehistoric Dawn]. Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous. Nine prehistoric eras, nine (ten) world keys. Moving Maze, Night Storm, Minus 100°, Capturing a Mosasaurus, Being Chased by a Tyrannosaurus Rex for 24 Hours... The game levels are constantly upgrading, and people are dying every second. However... Where is the tenth key? Will humans win in the end? (A magically modified prehistoric world, the setting is bizarre, please enter with caution)
