"What is it?" Li Ke became spirited and looked at Li with bright eyes.
"This?" Li Yin muttered to himself and pretended to be deep in thought.
Li Ke was a little anxious. This was an opportunity to show his face in front of the Emperor. After the court was dismissed, the Crown Prince Li Chengqian and the King of Wei, Li Tai, had organized their retainers to discuss this issue. As the King of Shu, he could not fall behind.
Seeing Li Ke's impatient face, Li Yin thought that he did not have any official position in the court. If he rashly entered the palace to offer advice to Li Shimin, it was inevitable that he would have the time to flatter and win favor. If he told this method to Li Ke, it would be much more effective than himself. Li Ke would also be grateful to him, but Li Yin was not the master who suffered losses." I can tell Third Brother this method, but Third Brother must give me Father's reward!"”|
Li Ke was delighted. Compared to his father's appreciation, this little reward was nothing. He said,"That's not a problem. Sixth brother, just tell me quickly. I'm really anxious to death!”
Taking Li Ke to the study, Li Yin picked up a piece of paper and drew out the plan of Chang 'an Fortress based on his memory.
Li Ke stood on the side and watched Li Yin draw out the 108 lanes of Chang 'an with a ruler from time to time. At this time, he couldn't help but feel a little magical. He didn't expect this sixth brother to be so well-hidden.
After drawing a preliminary plan, Li Yin drew some small lines on these roads and walked along the roads of Chang 'an City. Finally, he led this line to Jingchuan outside the city.
" Although there are five canals in Chang 'an, in the event of a rainstorm, the five canals will not only fail to drain the water, but will also cause the river to flow backward, making the waterlogging even more serious.”After finishing the drawing, Li Yin put down his pen and said.
Li Ke picked up the blueprint that Li Yin had drawn and looked at it again and again, saying,"Sixth Brother, what do these black lines on the road mean?”
"This is the root of solving the problem of Chang 'an's waterlogging, the underground pipeline!”
"Underground pipes?" Li Ke had never heard this new term before. He looked at Li Yin in confusion, waiting for his explanation.
"This is a facility buried underground.”In order to make it more vivid, Li Yin picked up a teacup and placed it in front of Li Ke." Do you see this teacup? The bottom of the teacup was pierced through. This was the pipeline. Now, the pipeline was buried underground, leaving a pipe opening on the ground. Once it rained, rainwater would enter the pipeline through the pipe opening and then flow to the downstream of Jingchuan outside the city. In this way, once it rained, the water would quickly dissipate, and the flood in Chang 'an City would be solved forever.”Li Yin studied engineering and construction, so he was naturally familiar with this problem. When he came back, he was already thinking about it.
"I see. It's really a divine plan. Why didn't I think of it?”Li Ke pointed to another line beside the pipeline." What is this line?”
"That was a rainwater pipe just now, and this is a sewage pipe!”Li Yin had been criticizing the toilet hygiene of the Tang Dynasty for a long time. He took this opportunity to solve it together. Before Li Ke asked, Li Yin continued,"This sewage is also drained, but it is not rainwater, but feces and urine. At the end of this pipe, build a huge manure tank. After settling, it will become natural fertilizer.”
Li Ke was stunned. He had never thought about this problem before. Now, the imperial court had sent people to pick out the feces and urine of Chang 'an City. Once the sewage pipeline was built, it would save a lot of money. Although he did not understand the manure pit at all, he could not wait to present this method to Li Shimin!
"Sixth Brother, you're really too smart!”Li Ke walked around excitedly. Li Yin was ashamed. This was not something he knew. It was plagiarism.
After explaining the general plan to Li Ke, Li Ke dragged Li Yin to discuss the specific details. After a day, Li Yin finally told him all the knowledge about the pipeline. Li Yin was tired and went to bed early, but Li Ke was excited all night as if he had lost his mind. The lights in the room did not go out all night.
The next day, Li Ke went to court as usual. He looked at the court full of confidence and smiled as he looked at his colleagues who were gathered together and still unable to do anything.
"Third brother is so happy and contented. Could it be that he has already solved the problem that father left behind?”Just as Li Ke was feeling smug, a voice came from behind him.
"My younger brother greets Your Highness the Crown Prince!" This voice was very familiar. It came from Li Chengqian, Li Shiming's Di son, the current Crown Prince.
"Third brother, please forgive me!" When the court session ended yesterday, he had also asked the officials of the Eastern Palace to discuss this problem and come up with a solution. Seeing that Li Ke had victory in his grasp, he could not help but ask.
"I only have some humble opinions!”Li Ke casually brushed it off.
Li Chengqian smiled. He knew that he couldn't get the truth out of Li Ke's mouth. Although his position as the Crown Prince was stable, he knew that the King of Wei, Li Tai, and the King of Shu, Li Ke, were both keeping an eye on him.
Just as he was thinking, Li Shimin walked into Taiji Palace and shouted,""Do you have a solution to the flood in Chang 'an?”
"Reporting to Imperial Father, your son has been thinking day and night and has thought of a way!”Li Chengqian bowed.
"Oh?" Li Shi Min looked at his favorite son and said,""Tell me!"
Li Chengqian said," The waterlogging in Chang 'an City is caused by the five canals being too narrow. I think that opening up the five canals will solve the waterlogging problem once and for all!"”
"The Crown Prince is right." Li Shi Min nodded in satisfaction.
" Father, I don't think it's appropriate to open up the five canals. Yesterday, when the court was dismissed, I personally investigated the situation of the waterlogging in Chang 'an. The five canals have all been flooded. If we open up the five canals, the flooding will be even more serious!”At this moment, the King of Wei, Li Tai, spoke.
Li Shi Min frowned," Then do you have a solution?”，He looked at Li Tai.
"Your son hasn't thought of a proper solution yet!”Li Tai looked ashamed.
After Li Tai said this, the court fell silent. Li Shimin said angrily,"Is it so difficult to solve the problem of waterlogging?”
Li Ke felt that the time had come. He stepped forward and said,"Father, your son has a good plan!”
"Ke 'er, tell me quickly!" Li Shi Min's heart was filled with hope.
At this time, Li Ke took out a blueprint from his sleeve and said,""Father, the solution to the flood in Chang 'an is on this map. Please take a look.”
"Hand it over!" Little Yellow Gate immediately took the blueprint from Li Ke and handed it to Li Shiming.
Li Shiming opened the blueprint and looked at the lines and points on it. He was puzzled."What is this?"
"This is the blueprint of the underground pipe network. This kind of pipe network is divided into sewage and rainwater…"
In the court, Li Ke talked non-stop, telling Li Shimin all the knowledge that Li Yin had taught him. He had the posture of arguing with the scholars. On the dragon throne, Li Shimin nodded repeatedly.
"Good!"
After Li Ke finished, Li Shimin shouted.
