Once, a red-eyed golden eagle ventured into the poisonous swamp in hopes of finding food. It was known to have a strong resistance against poisonous gases, but before it managed to find any food, it had already suffocated and died as a result of the colorful and yet poisonous air.
All the beings that lived in the poisonous swamp were equally poisonous. A small bite was fatal. There was not even a cure that one could use. Therefore, all the mortals and devils would avoid this place at all costs.
Nonetheless, it was a heaven for all the poisonous beings in the world. There were the poisonous snakes, frogs, scorpions, and even centipedes. All these poisonous animals lingered around almost everywhere in the swamp and could hide easily in a pool of mud or the bushes. These creatures would attack any passer-by with their fatal strikes.
