In the Imperial Study, the emperor was reading the letter sent by Zhao Yao. This letter detailed the production, usage, and maintenance of various watermills.
After reading, the emperor excitedly shouted a few times, "Excellent."
Seeing the emperor's jubilant and excited demeanor, Sun Kui was very curious. He thought to himself: What has Prince Han done this time to make His Majesty so happy?
"Sun Kui, go and summon Prime Minister He, Grandmaster Liu, the Minister of Revenue, and the Chief of Staff of the Ministry of Industry."
"Yes, Your Majesty." It seems that Prince Han has achieved something significant again this time.
A short while later, Prime Minister He and the others appeared in the Imperial Study. The emperor showed them Zhao Yao's letter.
After reading it, Grandmaster Liu and his companions all exclaimed, "Excellent."
The Chief of Staff of the Ministry of Industry held Zhao Yao's letter with both hands, staring intently at the various diagrams of watermills on it.
