In the next few days, Lu Qing focused on her Tiangong Institute, while Yu Mingchuan took Xue Yan to get familiar with their new inventions.

Like stirrups and horseshoes.

"Brother Mingchuan, all these things were made by Lu Qing?" Xue Yan is still floating after stepping on the stirrup to practice with Yu Mingchuan for a while.

If you step on this thing, you can fight steadily on the horse, even with a long gun. You don't have to worry about falling off the horse. How does the little girl's brain grow?

Yumingchuan nodded with pride on his face.

"Where the hell did she come from? Did you ask?"

In this regard, Xue Yan has become more and more curious.

"I won't tell you." Yu Mingchuan squinted at Xue Yan and continued to show him that the auxiliary soldiers spread salt on mutton and pork to make military grain.

"How can you be such a brother? Don't let me know anything..."

"Yes, how can you be such a brother? You always inquire about your brother and sister-in-law. What's your intention?"

Yumingchuan raised his chin and hated Xue Yanya.

"Wait, I'll ask her myself one day." before he finished, Xue Yan jumped away from yumingchuan.

"As long as you dare to approach her privately, all the green knives will be taken back."

"No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no

Xue Yan stopped and looked at yumingchuan with a flattering face. Yumingchuan was disgusted, but he continued to take him around.

Lu Qing has been a little annoyed recently, because as long as she teaches, Zhang Dan doesn't fall off. Even, he took a book and made records throughout the whole process.

Chen cangya painted her facilities on one side and did a good job.

Lu Qing wants to keep this man and specialize in engineering drawing.

Until a class, Lu Qing taught everyone how to put alkali when steaming steamed bread, so that the steamed bread would not be sour. Only then did he see that there was nothing painted on Chen cangya's drawing paper.

Zhang Dan still carefully wrote down every word she said, a hundred times more serious than those little people who just listen but don't remember.

After each class, Zhang Dan will find Lu Qing and ask some questions related to the course, and the questions are just right. They are basically the details Lu Qing didn't pay attention to when teaching.

Add these details to make this class perfect.

Lu Qing has an impulse to grab Zhang Dan's small book and print it.

When the Tiangong Institute opens for a year, maybe they can really compile a book called Tiangong Kaiwu.

I don't know what song Yingxing thought about this more than a thousand years later... (Note: Song Yingxing, the original author of Tiangong Kaiwu in the late Ming Dynasty)

Many farmers from all over the world are artisans.

After old man Liu taught everyone the skill of weaving baskets, he didn't see anyone else competing for business. On the contrary, the business of the old man's family became better. These craftsmen also began to teach their skills in the Tiangong Academy.

They spend their whole lives touching, crawling and rolling at the bottom. It's worth it if they can be called sir.

What's more, every time I sit in the first row, it's the prince of Liangguo! If you can be called Sir by the prince, isn't that the emperor's teacher?

This is just a good thing that smoke comes from the ancestral grave. After people know Zhang Dan's identity, their enthusiasm is higher and higher.

Therefore, one month after the opening of the Tiangong Institute, people came out to teach silkworm, weaving, planting, fishing and hunting, and even how to breed and deliver animals.

There is also an old man who said that he was born as a royal chef and insisted on teaching everyone how to cook Royal meals. In particular, there is a prince in front of him, and the old royal chef wants to show off his cooking skills.

As a result, because everyone was still poor, at the stage of food and clothing, they couldn't find those materials at all and scattered in a crowd.

It made the old imperial chef very sad.

Lu Qing couldn't bear it. He invited the old imperial chef to the soldiers' area and talked with him about how to cook delicious food with local materials. After that, the old imperial chef was greatly inspired and planned to teach again in three months.

A fat man named Guo Junda taught Lu Qing how to do business a month after his class in the Tiangong Academy of technology.

The fat man has a very flexible mind and an excellent memory. He can receive what he makes in the western regions and what price he can sell in all parts of the Central Plains. How much he consumes along the way and how much he finally gets.

So, when lying in bed at night, Lu Qing told Yu Mingchuan about it. Obviously, this person is more suitable for Liu Chen. Although Liu Chen is also good at doing business, he is directly slag by seconds compared with this fat man.

"Madam thinks it's easy to use. Just bring it and listen to her for her husband." Yu Mingchuan stroked Lu Qing's back with a smile and moved leisurely.

"Bah, I'm happy. Yumingchuan, I think you're getting darker and darker. You always pit me like this. You know what?" Lu Qing knocked off his hand and felt that he had become a cat again.

"Good, my name is Yulang. My wife is so capable. I'm really blessed to be my husband. Where can I pit my wife?" said yumingchuan, holding Lu Qing close and hugging her in his arms.

"Hum, you're always kidding me now. I'll tell you what's going on first. Just nod your head. You'll benefit again, and you don't owe me a favor, black hearted bastard!" Lu Qing angrily poked Yu Mingchuan's chest, but his fingers hurt.

"Whoever says I don't owe you, I gave myself to you. What you gave me is also for yourself. How can you say that I got benefits? These are your wife's, and so are I."

The finger was caught and put on yumingchuan's lip. The thin cocoon was gently rubbed and itched.

"These seven turns and eight turns are a mess. I just tell you that you can't wait for me to jump into the pit in the future. If you need anything, tell me directly. I'll give you what I have. Don't think I don't know you sent someone to stare at me all day." Lu Qing moved a little, and the itch will itch to his heart soon.

"It's good to have a wife. I want something from my wife now. If my wife has something, please give it to me." Yu Mingchuan's beautiful eyes suddenly lit up and looked at Lu Qing.

"What?" Lu Qing suddenly became alert.

Yumingchuan looked at Lu Qing's robe with a smile on his face. The next moment, he ran down very quickly

"Yumingchuan -" Lu Qing grabbed the bastard's head and blushed.

After another period of time, the weather was getting colder, Lu Qing had begun to wear cotton padded clothes, and the framework of Wubao had been built and was preparing to stop work.

After listening to Guo Junda twice, Lu Qing used her killer mace.

"Brother Guo, if I teach you a simpler accounting method, how about you come to our Yumen pass to do things?"

Lu Qing looked at Guo Junda with a smile, but the smile was too bright, and his teeth showed more, just like a wolf looking at a sheep.
