In the middle of the dungeon, Huanzi notices the prince's highness and asks him to follow him closely. He tells the prince that there is a hidden room in the dungeon and that the prince should get out of there. The prince is shocked at the sight of the room and asks what Huanzi is thinking. Huanzi tells him that the secret room is in the kingdom of the liu-yue, and that even the local people may not know about it. He says that he has already investigated the place and that he will tell the prince everything when the right time comes.
