Chen Mo, who dropped out of college and was heavily in debt, found a job that was said to be "state-owned enterprise establishment, five social insurances and one fund, including food and accommodation" in order to make a living - working as a breeder at a "Shanhai City Endangered Animal Conservation Center" that was on the verge of bankruptcy. He originally thought that work consisted of shoveling shit, feeding people, and battling wits with mentally unstable colleagues. Until he discovered that the lazy cat taking a nap here could smash the alloy door with one claw; the old turtle turning its belly in the pond carried a Bagua array on its shell; the parrot that cursed him every day actually spoke the language of ancient dragons... And his seemingly unreliable colleagues: the alcoholic cleaning lady who is a master of talismans, the gossipy cafeteria Aunt Li who is good at refining ancient elixirs, and the bald director who holds a thermos cup all day long and once killed an evil god from outside the sky with a sword. This is not a zoo, it is a [prison] where countless ancient gods and demons are suppressed! His job is not as a breeder, but as a [Warden]! When the gods and demons resurrect, the city is about to collapse, and the most dangerous combat forces in the world are all on the feeding list of Chen Mo, the "trainee breeder". "Um... Brother Jiuying, can you pay for the food today? You have nine heads and you eat nine portions of my food!"
