After solving his father's problems, Master Wu tells his son to focus on practicing his magic. He wants to see King Lu, but the old man is too busy. Master Wu scolds the brat for interfering. He says that the dagger in his hand is a magical weapon, which can break through spiritual power. The old man says that they are honored guests at the royal palace, and that Master Wu should not be so indifferent. He tells the brat to go first and look at the depths of imperial city formation, and then he will go ahead to meet the brat. The brat says that he is too naive to believe that there is such a powerful formation in such a small kingdom, but Master Wu says that if he is cocky, he will break the formation for him. The second master, Yao xi , is rumored to be a gentle and domineering man, but he is said to use the jasper lake to draw thunder into his body, which penetrates the chrysanthemums and the brain and goes straight to the profound.
