Rescued by a big fish while unconscious, the boy wakes up and finds himself in an illusory space. The little boy was guided by the fish elf, traveled between the heavens and the earth, and finally the big fish collided with a huge boat, the boy returned to the real world, it turned out that all this is the boy again under the tree to do a dream. After the boy left the hall, the fallen leaves gradually turned into fish elves and floated back into the fish. I do not know whether the boy dreamed of the fish elf, or the fish elf dream of traveling the world.
