In this short scene, Gu-changge tells his brother that he is fated to kill him. He tells him not to go too far if he insists on supporting the girl. He also tells him that he has changed his mind about killing his brother. He says that he had planned to make him hate his brother and then let him slip away, but now he thinks that killing him is a good idea. He asks the other party if they want to go along with the killing of his brother, and they all agree to go. He then tells them to watch out for the seventh princess, who is the master of his sea king palace, and tells them that he will save them if he kills him. If he does kill him, he will be able to capture the love of the seven princess, and also gain favor from the master. He explains that each of his swords has a little power, which is why he threw the girl to him. The blood and energy in the girl's body can be used to strengthen the muscles and bone in the body. He warns his brother not to be proud of himself, because one day he will trample him underfoot, and if he wants revenge, he can prove it to him
