The pitter patter tells gao that they've been trying to figure out a way to manage the laws of nature, but they haven't found anything. He tells the pitter to look at the waterfall, because it's only a source of water for the rangs. A few years back, an elder tian found a baby boy floating in the waterfall. The lord thinks that the baby floated from the river and entered the outside world, presumably from the ring. After following along the river, they found the entrance. The ring has created a magic circle that only dragons can pass. Therefore, mortals are unable to enter and exit the realm. gao asks if they can go look for the underground river to see if there's an entrance to the river. The patter says he's not in such a hurry. He's already found the mushroom. He says that if they follow the river to the swamp, they can reach the swamp in two hours, which seems like a good idea. He also says that the ring needs to keep the river a secret, since it seems like the prince wants his people to stay in the realm, not leave it. The Pitter patter puts down his sword, and gao tells him that his brother is a prince. He was born into the royal family, which means he has always been a noble gentleman. He compares his brother to the eldest son of the emperor, who is the heir to the throne. He and his brother are very similar
