The story opens with a description of the dragon clan, which is considered to be the strongest of all mythical clans. It is rumored that their dwellings are filled with gold stolen from other clans. They come to their dwelling in a mountain far away from their usual dwelling. The narrator asks where the gold is, and the narrator replies that he does not want to live near such a dwelling. He wants to stay in a place where he can sleep on grass. He wakes up to the sound of a buzz and a growl, and he decides to build a castle. He has enough grass and mosquito to make a castle, but he cannot make it extravagant. He hears a rumor that a dragon is flying, so he tells the people to gather and build a house. He tells them that he is the king of the north mountain, and that he wants them to become his loyal servants. They are honored, and they eagerly await his orders. The rumor has spread throughout the forest, and now the king has brought along a demon advisor to help him build a new kingdom. Everyone is excited about the new king, but the narrator tells us that he has something wrong with the advisor. He says that the advisor seems happy for the king's sake, but that the humans are back. The king has to work hard to build an extravagant house for him.
