A long time ago, there was a terrible earthquake. As a result, the otherwise carefree monkeys had to flee to safety. With the passage of time, coupled with ignorance and superstition, monkeys gradually divided into two groups-tree monkeys and ground monkeys. Cam, the tree monkey, has always been the son his mother was particularly worried about, because he was not as honest as his brother. Cam was active, bold and always did something unexpected. There is a tradition in the tribes of counting monkeys that they should firmly hold on to the branches and never fall under the trees. Because in their view, everything is good at the top and bad at the bottom. Legend has it that the world under the tree is full of demons, and once it falls, it will be irrevocable. The other tree monkeys were very scared, but Cam didn't think so, and he was very curious about the world below. One day, while looking at the world below, Cam fell, and all his companions were sad for him, thinking that he was bound to die. But fortunately, Cam was saved by the King of the Earth Monkey who happened to be passing through the jungle and took him back to the palace for treatment. Cam soon recovered. As Cam expected, there is no devil under the tree, and the land monkey has evolved and developed to a certain extent, and its civilization is much higher than that of the tree monkey. But in contrast.
