This messenger told the Jing River Dragon King that it would rain tomorrow, at the exact hour and with the exact number of raindrops. Yuan Shoucheng calculated it precisely without any discrepancy.
The Jing River Dragon King couldn't help but exclaim in alarm, "Is there really such an extraordinary person in this world? Could it be that I am going to lose?"
An adjacent strategist then said, "Great King, there's no need to worry. You are the Dragon King; if the Jade Emperor orders you to bring rain, you can just delay it a bit, or reduce the amount of rainfall. Wouldn't it be Yuan Shoucheng who loses then? Afterwards, just go right to his door, drive him out of Chang'an, and protect our aquatic tribes."
After hearing this, the Dragon King joyfully agreed, thinking, "That's right, I am the one in charge of rainfall. By withholding a bit and delaying, wouldn't Yuan Shoucheng lose? Then I can simply smash his signboard to pieces!"
