Lin Bei is an intern at the zoo. He is responsible for shoveling poop, feeding, and being bossed around by old employees every day. Until one day, a group of lions lay down in front of him and called "King", and a group of monkeys handed him bananas and begged him to become the king of the mountain. Colleagues thought he was good at imitating animal sounds, and his boss thought he was unlucky, until the circus next door came to destroy the place, and the animals collectively went on strike and rebelled. Lin Bei snapped his fingers, and all the animals in the city lined up to work! From the time he was expelled to when everyone in the city begged him to be the one to speak, he only spent seven days as an intern.
