People in Datang have been expelled from school

Li Zheng looked at the sky of the village and said: "Speaking of this kind of words is always very heavy, everyone has to go through this."

After receiving the account from Wu Mei, Li Lizhi said: "We bought another fifty stone coal mine from Li Xun. She agreed quickly and was willing to give us a lower price."

Li Zheng said: "She will weigh the pros and cons. If she refuses to lower the price, she will purchase less in the future."

Li Lizhi said: "Even if the profit is reduced, she still wants to keep the business in Guanzhong. This woman understands it very clearly."

Looking at Li Lizhi's expression, Li Zheng said: "Why do I feel that you and her have a feeling of matching each other."

Li Lizhi raised her chin arrogantly and said, "Is there? I don't think she will be my opponent."

Li Zheng nodded decisively, "Well, you are very confident."

Glancing at Li Zheng pretty, Li Lizhi said: "You didn't give it to me. Jingyang has such a large scale of operation. In your words, we have the best foundation and brand. If we operate in the past few years, we will The business that Jingyang goes out of is all rushing for."

After several years of precipitation, Jingyang's business is indeed the best now.

And there are guarantees.

After Jingyang's operation reaches a certain scale, it is also a kind of dependence for others.

As long as the business does not go wrong, everyone is willing to make money.

Changan
Li Shimin saw a memorial that Shanhaiguan needs to be rebuilt.

Holding an oil lamp in his hand, Li Shimin looked at the Shanhaiguan map hanging on the wall, and looked for the location of Shanhaiguan.

Li Shimin said in a low voice, "What's going on in Shanhaiguan?"

Wang Ding replied: "Shanhaiguan is adjacent to the East China Sea to the east, and the sea wind is strong, and the seawater erosion is serious. It was discovered a few years ago during the Eastern Expedition to Koguryo, but it is more serious now and urgently needs to be repaired."

Now there is no shortage of money in the court, Li Shimin nodded and said: "I will discuss with Fang Xuanling and the others, let the household department prepare it."

Wang Ding bowed and said, "Here!"

Shanhaiguan need to repair?
Li Zheng, who was in Jingyang, soon got the news from Xu Jingzong.

Li Zheng called Li Yifu again and asked, "How many members of our engineering team can be transferred now?"

Li Yifu took out the dossier and said: "Master Yan's road construction work is coming to an end, and many manpower has been spared. Now we can transfer more than 1000 people."

It is a big project to repair Shanhaiguan.

Li Zheng looked at Li Tai who was cleaning the stables and said, "His Royal Highness King Wei."

Li Tai, who was busy shouting in the stables, poked his head out and said, "What's the matter?"

Li Zheng smiled and said, "Does His Royal Highness King Wei want to go to Chang'an?"

Li Tai glanced at Chang'an's direction and said, "No."

Li Zheng still looked at him, "Why?"

Li Tai shoveled the horse manure onto the cart and said, "Every time I go to Chang'an, I feel bored."

Walking into the stables, Li Zheng said again: "Then you can't stop contacting your father, queen and queen, right?"

Li Tai stopped the movements of his hands and relaxed his waist slightly, and said, "I often ask people to contact me by letter, besides, my father, queen, and queen know about my situation in Jingyang."

The prince is here in Chang'an now, and the prince is backed by the eldest grandson's family.

Entering Chang'an is like entering a quagmire filled with muddy water.

Those schemes and tricks will come out of the way.

It's not that Li Tai is unwilling to fight Li Chengqian.

I don't know what drained Li Tai's fighting spirit.

Li Zheng said to Li Tai: "Then you write a letter quickly, saying that Jingyang's engineering team can take over the repair work of Shanhaiguan."

Li Tai frowned and said, "You want to do business with my father."

Li Zheng smiled and said, "His Royal Highness King Wei is really smart."

Li Tai smiled disdainfully and said, "I already know what your engineering team is for."

Seeing that Li Zheng had prepared his pen and ink, Li Tai also stopped his movements and began to write a letter.

Halfway through writing, Li Tai looked up at Li Zheng.

Li Zheng wondered, "What's wrong?"

Li Tai bit his pen and said, "What about the price? What price is right?"

Li Zheng said: "Don't write the specific price first, just say that the price is suitable and absolutely affordable."

Li Tai looked at Li Zheng with a guilty conscience, and still wrote down what Li Zheng said.

After writing a letter, Li Zheng swiftly prepared the sealing wax and handed it to Xu Jingzong, saying: "Send it to the palace as soon as possible, and say that His Royal Highness Wei Wang gave it to His Majesty."

Xu Jingzong left in a hurry after receiving the letter.

Li Tai scratched the back of his head and said, "Do you think I was blackmailed by you?"

Li Zheng spread his hands and said, "Did I threaten His Majesty? Not at all."

Li Tai frowned and glanced at Li Zheng, "Forget it."

After speaking, Li Tai plunged into the horse pen and started working.

Li Zheng said to Li Yifu: "You go back first and sort out the number of people and the roster that can be arranged."

Li Yifu nodded and said yes and went to work.

Li Zheng returned home and came to his study.

In fact, there have been several repairs to Shanhaiguan in later generations.

Li Zheng took out some historical records of building materials.

As early as in the cement of the Roman era, scientists discovered a lot of mineral high-alumina tobernaite, which is volcanic rock.

This substance will become stronger after being exposed to seawater.

Volcanic rocks can be obtained in the Changbai Mountain area north of Shanhaiguan.

Combining volcanic rock with ordinary cement can create buildings that are resistant to seawater corrosion.

This is not difficult.

According to the drawings recorded in historical materials, Li Zheng sketched the appearance of Shanhaiguan. Historically, Shanhaiguan has been rebuilt several times.

In fact, during the Ming Dynasty, Shanhaiguan was refurbished several times.

Moreover, Shanhaiguan in the Ming Dynasty was directly connected to the East China Sea.

Li Zheng began to outline the appearance of Shanhaiguan according to the blueprint of Shanhaiguan on the Great Wall of Ming Dynasty.

Xu Hui saw that Li was drawing something carefully in the study.

Put a cup of tea aside.

Xu Hui stood by for a while, it seemed that Li Zheng didn't notice her.

I also didn't want to disturb Li Zheng at this time.

Xu Hui walked out of the study lightly, and closed the door for Li Zheng.

Li Zheng sketched the drawings of the Great Wall of Ming Dynasty, from the thickness of the wall to the height, and various dimensions.

After working until night, Li Zheng finally finished the blueprint.

The drawing is not complicated, but it is based on the current situation of Shanhaiguan, and some modifications have been made on the style of the Ming Great Wall.

Drawing drawings is not too difficult.

If Li Zheng doesn't cook on weekdays, Xu Hui cooks most of the time.

Xu Hui's cooking skills at home are those of Li Zheng's recently.

At home, Xu Hui was the first to follow Li Zheng.

Xu Hui is also the person who has the deepest knowledge of Li Zheng's culinary skills.

Li Zhi came back early, saw Li Zheng and said: "I heard that the teacher is going to take over the fortification of Shanhaiguan."

This matter cannot be hidden, Li Zhi wandered around the village with Shangguanyi all day long, it was difficult for him not to know.
