Who violated the jade emperor's will in the journey to the west?

I forgot my name. A dragon king went against the jade emperor's will. A fisherman gives a fortune teller a golden carp every day, and he tells the fisherman when to get off the net and catch the fish. This let the dragon king in the water know. The dragon king turned into a man and went to the fortune teller to smash the venue and let him calculate when it would rain. The fortune teller told the Dragon King when and how many hours it rained. The Dragon King said that if it didn't rain, I would smash your shop. As a result, the Dragon King received an imperial edict from the Jade Emperor as soon as he got home, telling him that it would rain tomorrow, and the time and point of the rain were exactly the same as those calculated by the fortune teller. At this time, one of the dragon king's men told the dragon king that it would be different from the fortune teller's calculation when it rained. Later, it rained less the next day, and finally he was sentenced to death for not raining according to the jade emperor's will.
