People in Datang have been expelled from school

Chapter 848 Talking about Repair

Several women in the hall were talking, and Li Zheng didn't listen to what they said.

I was thinking about how to make mosquito coils in my mind. I remember that the earliest record of mosquito coils was in the Southern Song Dynasty.

But earlier, incense was used to repel mosquitoes.

If you really want to go back, there was such a technology as early as the Qin and Han Dynasties.

There is no incense in the Lizheng Hall, which is mainly due to the cause of Empress Changsun.

The maid came over and said a few words beside Empress Changsun.

Li Xun and Wang Qiaoer stood up and said, "Queen, we both have to go to see the elders in Chang'an, so we will leave first."

Hearing what the two of them said, Empress Changsun said with concern: "Aren't you going to stay for dinner?"

"The elders had agreed in advance, but they just didn't want to go."

"That's right, you still have to respect your elders, and I won't embarrass you two, if you must stay next time."

The two daughters bowed and bowed after hearing what Empress Changsun said.

After they left, Queen Changsun's smile disappeared and she stood up and said, "Let's stay and eat."

The maids began to tidy up the Ganlu Hall, and the meals were being served on the dining table one by one.

At noon, Li Shimin came to Ganlu hall.

Prince Li Chengqian followed Li Shimin.

Everyone sat down, Li Chengqian asked Li Zhi, "Did you study well in Jingyang?"

Li Zhi replied sensiblely: "Recently I have been studying some mechanics, such as air resistance, buoyancy, pressure, and interaction force. These days, I am studying water pressure."

"Water...water pressure?"

Li Chengqian didn't understand for a moment.

Li Tai said: "Does the prince know what water pressure is?"

Li Chengqian: "..."

The scene in front of him was very interesting. As the elder brother, Li Chengqian wanted to preach to Li Zhi with a stern face, but he was a little speechless at the moment.

Li Tai said with a smile: "Child slave, the crown prince has always been helping the emperor with state affairs. His Highness the crown prince will not study this kind of thing."

Li Zhi nodded, "In fact, the principle of water pressure is not difficult to understand. If you want to learn it, you can ask the young slave."

The little son who was sitting next to the queen mother also said: "Brother Huang, my son is also learning mathematics recently, and he has already learned algebraic operations."

"Algebra..."

Li Chengqian looked at Xiao Si, who was not yet ten years old.

Li Shimin looked at his sons and daughters sitting on their respective desks. It had been a long time since he had seen Xiao Si and Zhinu. The two children had changed a lot, especially Zhinu's body grew so fast that he had already grown so tall before he knew it. .

Xiao Si's complexion is also much better than before, and there are more smiles on his face.

Li Shimin said, "Let's eat."

Everyone started to eat.

Xiao Sizi and Li Zhi, who were used to eating at a big table as a family, obviously didn't adapt to the old rules of the palace. This kind of eating at separate tables always didn't feel like a family eating together.

Because everyone was sitting at their respective tables, far apart, there was an inexplicable sense of alienation.

The little boy struggled to drag his desk, and sat at the same table with Li Lizhi, sitting next to his sister. The little girl grinned at her father.

Li Shimin didn't blame him, he just smiled.

Sitting next to his imperial sister, Xiao Si finally had the appetite to eat.

Li Zheng was eating the food at his table, but the braised pork in the palace was a bit too sweet.

Probably too much sugar.

And the things in front of him are all meat, but there is no vegetable.

Looking at it this way, it really seems that you, Li Shimin, are very wealthy. It is a big business to invite people to eat. During this period of time, Li Shimin has earned a lot of money. In addition to the two years of bumper harvests, tax revenue and weapon business, Li Shimin’s income is very good. .

After the meal, the little Sizi and the eldest grandson Queen, Li Zhi left.

Li Chengqian and Li Tai also left.

Wang Ding walked into the Lizheng Hall, and there were only four people left in the hall.

Li Shimin looked at Li Zheng and Li Zhi and said, "How are you preparing for the repair of Chang'an City?"

Li Lizhi first said: "Father, my daughter has calculated an account for the repair of Chang'an City, excluding manpower and other miscellaneous expenses, it will roughly cost 12 guan."

"12 sticks!"

Hearing this number, Li Shimin looked at his daughter in surprise, Li Zhi could still say it.

Li Lizhi took out a pre-prepared file and said: "This is calculated by my daughter based on the current situation in Chang'an. There are drainage canals in Chang'an's streets with a total length of 31 kilometers, and the drainage channels are all over Chang'an. At that time, houses will need to be relocated." The rectification, as well as the filling of the terrain, counting all the costs, the amount of 12 guan is very appropriate."

Li Shimin looked at his daughter, feeling a little complicated at the moment.

Li Lizhi went on to say: "Father, Jingyang cannot do business that loses money."

After the words fell, a young eunuch came up and said, "Your Majesty, Zhongshuling and Dushangshu have arrived."

Hearing that Fang Xuanling and Du Ruhui had come, Li Shimin felt relieved and said, "Let them in quickly."

Looking at Li Shimin's posture, it seems that today is really prepared.

Fang Xuanling and Du Ruhui walked into the hall and first saluted.

Li Shimin said, "Fang Xuanling, Du Ruhui, tell me your views on the renovation of Chang'an City."

Fang Xuanling and Du Ruhui looked at Li Zheng and Li Lizhi together.

Li Lizhi said: "Father wants to build Chang'an City. We in Jingyang thought that the fortification was huge and required a lot of manpower and material resources. According to our current estimate, the cost should not be less than 12 guan. What do you two think?"

Fang Xuanling said: "Princess Changle, 12 guan is not a small amount. If you take out 12 guan, how much can Jingyang earn?"

Hearing this, Li Shimin nodded secretly. Sure enough, Fang Xuanling was very reliable, and used Jingyang to counter it.

Du Ruhui said: "Chaozhong can let Jingyang earn some money, but it's 12 guan, isn't it a bit inappropriate?"

After the two finished speaking, Li Lizhi tapped her fingers on the table as if she was thinking.

Li Shimin looked at Li Zheng, wanting to see how long this kid could sit still.

After thinking for a while, Li Lizhi said: "The order of Zhongshu and Du Shangshu mean that 12 guan is too expensive?"

Fang Xuanling smiled and did not speak.

Li Lizhi went on to say: "If you think the price is too high, Fuhuang and Chaozhong can of course find other people to rebuild the drainage canals of Chang'an City. Others may ask for a lower price, but do they have the construction ability of Jingyang? How long will the construction period be?"

"It took Jingyang only nine months to repair the [-]-kilometer-long official road. May I ask Fang Xiang, Du Shangshu, can you find something as efficient as Jingyang?"

Fang Xuanling said again: "Then how long can Jingyang give us?"

Li Lizhi said, "Six months."
