At least Jingyang has cooler places in summer.

Li Zheng whispered: "Your father is here to come to escape the summer heat, but I won't charge the rent in other courtyards, but you have to pay for all the expenses on weekdays. In other words, your father is here to escape the summer heat, but you can't eat and drink for nothing."

Li Lizhi smiled and said, "I'm going to write a letter to my father now."

Although the profit of repairing the drainage channel in Chang'an City is not too high, the 5,000 guan per year in the future can also be regarded as one of the capitals for retirement.

Li Zheng came to Jingyang Academy. There are only a few masters in Jingyang Academy today. Zhang Gongjin, who came to the academy to teach, Li Chunfeng, Chu Suiliang, Sun Simiao, and Yan Liben.

Each Master has a separate room, which is considered a place where they work.

On weekdays, Sun Simiao and Zhang Gongjin didn't stay in the academy for too long, and they were busy with their own affairs after class.

What caught my eye when I walked into Yan Liben's office was stacks of drawings.

Yan Liben raised his head and saw Li Zheng a little surprised, "You don't see you walking around the academy on weekdays."

Li Zheng sat in front of Yan Liben and said, "I'll discuss with you about repairing the drainage channel in Chang'an City."

Yan Liben put down the brush in his hand, took out a letter and said, "A few days ago, a memorial was sent to me and also talked about repairing the drainage canal in Chang'an City. However, is the 120,000 guan of silver too little? Even if this money is enough to order the drainage canal in Chang'an, it may even be compensated in the end."

Li Zheng nodded and said, "You don't have to worry about this. I have a drawing here and you can take a look."

Yan Liben took the drawing handed over by Li Zheng with a doubt, looked at the content on it and said curiously: "Is this?"

Li Zheng explained: "This is a model I improved based on the idea of ​​prefabricated plates. In fact, we make the stone troughs of these drainage channels according to the size and build them directly into the drainage channels."

Yan Liben looked up at the drawings and looked up at Li Zheng, "This method really saves time and effort, and also saves money."

The drawings are filled with rectangular hollow grooves, with openings above them.

After looking at it for a long time, Yan Liben said: "If this happens, not only will the ditch be very clean, but it will also be very convenient to repair it in the future. How did Chang'an Order come up with this method?"

Li Zheng shook the fan and smiled awkwardly.

Some fantastic ideas are really useful. Yan Liben nodded and nodded, "If you do this, it will indeed make the cost very low. The originally complex renovation fortifications will be much simpler."

After saying that, Yan Liben said again: "I will arrange for the students to design the sizes, and then arrange for them to try it out."

Li Zheng said: "I'm working hard."

Yan Liben bowed and said, "I have learned a lot from you, but I can't say I'm working hard. If you have more advanced skills, I'd like to learn more."

As he said that, Yan Liben took out the ditch in Chang'an City and began to design the drawings.

When he walked out of the academy, Li Zheng met Li Ji again. Now Li Ji looks a bit fatter in middle age.

Li Ji sat lazily under the shade of the tree, with a pot of wine beside him, and was drinking chewy bites with the wine bowl.

Li Zheng walked closer and saw that there were still ice cubes in the wine.

"General Li Ji is having a good life."

Li Ji looked up at Li Zheng and said, "I have been fighting in the north and north for the first half of my life. I haven't lived a good life well. I want to live a comfortable life in the second half of my life."

Sitting next to Li Ji, Li Zheng said, "Your Majesty is coming to Jingyang to escape the summer heat in a few days."

"After summer, Chang'an, it will be so hot that it will make people unable to live. Most wealthy families will buy houses outside and go to the summer heat every year."

After saying this, Li Ji stared at Li Zheng and said, "How is the matter with the five surnames?"

Li Zheng said: "Now it has opened a breakthrough."

Li Ji whispered: "I heard that the Lu family has lost Fan Yang?"

"Now Duan Lun is watching in Fan Yang." Li Zheng said relaxingly while sitting on the ground, leaning against the big tree, "It was said that the scholars of the Lu family who caused trouble gave Duan Lun the chance to start. However, I think there are many tricks in this matter, just say that those scholars will not cause trouble sooner or later? But after Duan Lun arrived in Fan Yang, he caused trouble?"

Li Ji smiled and said, "It's really a coincidence."

"Are there no His Majesty among those scholars? The timing of this divine assist is too soon."

Li Ji smiled and said again: "Those old guys of the five surnames are not easy to deal with. In the past, the five surnames would underestimate them. Now you print thousands of books a day, and the five surnames would be afraid of you."

Li Zheng said, "The General has something to say."

Li Ji whispered: "Li Zheng, you are a smart person, but most of the smart people in the world can't live long because they are too smart."

"The general mentioned Yang Xiu next to Cao Cao, his fate is indeed not very good."

Li Ji took a sip of wine and said, "But there is a big difference between you and Yang Xiu. Sometimes when you think about it, you are wise and foolish. Many people think you are stupid. You love money and don't have power. This is your always reliance. If you take a few more steps forward to power, the abyss in front of you may be a thousand feet tall."

"Why is the general of the land so deep today?"

Li Zheng asked as he looked at him.

Li Ji sighed: "I am going to Lingyan Pavilion."

Li Zheng nodded, "General Li Ji is the founding general, so it is natural to go to Lingyan Pavilion, of course I have to go to."

Li Ji took another drink and said, "I have to say that I have always been obeying Li Jing's military strategy, Zhang Gongjin's strategy, and Yu Shinan's talent and knowledge, but I am not convinced by Cheng Yaojin, an old man. Why is my ranking in Lingyan Pavilion below Cheng Yaojin!"

After saying that, Li Ji took another sip of wine.

It turns out that Li Ji was drinking because he was not convinced of Ling Yange.

Looking at Li Ji's expression of annoyance, Li was about to get up but found that Li Ji's big hand was pressed on his shoulder and could not stand up no matter how hard he was.

"General, I'm still making soup at home. I'm afraid it will be messy if I don't go."

After saying that, Li Zheng was about to stand up, but he saw that Li Ji still had no intention of letting go.

Looking back, Li Ji was staring at himself with an old face, "General, if the wine is not enough, I'll go to our wine cellar to get some more."

Li Ji's eyes were covered with bloodshots, "Li Zheng, I usually see you as a smart boy. Is there any way for you? Lingyan Pavilion has not yet announced the list. It would be too late to let His Majesty re-arrange it now."
