When fang returns to the kingdom of Lu, he will have already killed the king of Luzhengheng. The king's highness is eager to protect the king, like a watchdog of the Fang family. The highness tells fang that he has just returned from five years of exile in the sixth realm, and that he cannot even meet his old man. Worried that the king will die soon, fang tells the highness that he can cure the king with a sixth-ranking morning dew pill. Believing that the poison is so strong that it can be cured in only two days, the old man urges fang to return. He also tells changlin that fang has poisoned Lu with the scorpion king poison. .
