Before going back, Lu Qing asked Mr. Sanshan to name the school.

After thinking about it, Mr. Sanshan picked up his pen and wrote down three big words: Tiangong Institute.

"This is the name of the school of my nephew's daughter-in-law."

Lu Qing happily took the paper, dried the ink, said goodbye to Wu Sanshan and Han Shuo, and went straight to the small craftsman area.

Lu Qing took the three words apart and gave them to the mason, blacksmith and carpenter respectively.

After setting the size for them, rub down the words to be carved, and then give them three days to see who can carve them.

After returning that day, Lu Qing was elated and asked Huo Jing to find someone to mount the three words and hang them in the largest ladder classroom.

In the evening, when yumingchuan came back, he told Lu Qing another good news - the first phase of Wubao was completed.

"I'll see it tomorrow!"

Under the thin quilt, Lu Qing hugged yumingchuan's waist and rubbed his face around his neck. It's a good feeling that everything is in order.

"OK, but madam, if you rub around again, I can't control it." yumingchuan leaned against himself with a big hand holding Lu Qing's ass.

Lu Qing twisted him a few times and became honest. He didn't dare to move any more. However, after falling asleep, he was still dishonest. The whole man hung on yumingchuan like an octopus.

Yumingchuan sighed and felt that time was too slow. If he went on like this, his spirit must be consumed by this little thing.

Early the next morning, Lu Qing rode Xinghe and Yu Mingchuan rode Dahei and galloped all the way to their Wubao.

Xue Yan didn't come back last night, so he made do in Wubao all night.

The first phase of Wubao was built in the mountain. It was made of local materials, with the valleys on both sides as the walls. In addition, some holes were dug as windows, which can not only spy on the outside, but also arrange bows and crossbows.

What makes Lu Qing stunned most is that the mountain walls on both sides are chiseled into an outward inclined angle by them, so that even if the enemy gets under the fort, he can't climb at all.

This part belongs to the fortification. It is the area to build houses on this fortress hidden in the mountain. Construction has not started yet.

When Lu Qing passed by, he saw several craftsmen marking the upper open space of the bunker. When Lu Qing and Yu Mingchuan came, they saluted one after another.

Lu Qing only spent a few days with these craftsmen when he first taught how to use cement and steel bars. These people naturally admire Lu Qing from the bottom of their hearts.

They now use materials that they have never seen in their lifetime as craftsmen. The buildings they make are stronger than any work they do. With this skill, they can even be famous in the world in the future.

They did not expect that this handsome young man would pass on his amazing skills to them.

Lu Qing felt that these things might as well be scattered and used by everyone, so that she would take less risk.

Recently, their steel-making workshop and farm tools are almost finished, and Lu Qing asked them to make steel bars.

The process of steel bar is much simpler than that of making weapons, but there is a great demand, so now dozens of craftsmen are responsible for it.

Lu Qing plans to build two reinforced concrete bridges on the Beida River after the construction of Wubao, so he doesn't have to cross the floating bridge every day.

Xue Yan was very happy that his craftsmen had mastered the reinforced concrete technology. He decided to go back and use this method to reinforce his Wubao again.

Before that, they must build this ancient and rare strong fortress first.

Because of reinforced concrete, they can build higher buildings above the bunker.

At present, it is planned to build a five story castle first, with the largest area at the bottom, which is mainly composed of various halls.

The upper four floors are used for living.

The residences of Lu Qing and Yu Mingchuan are on the top floor, which is theirs.

Just looking at the design drawing, Lu Qing was very happy. Finally, there was a big house with a wide view to live in!

So after returning, Lu Qing announced the opening of Tiangong academy the next day!

Because the first lesson she teaches will be making glass!

Her big house must be bright and transparent, and can shelter from the wind and rain.

In the future, she and yumingchuan's children will live here, generation after generation.

In fact, the day before yesterday, Fang Jiming had announced the opening of the Tiangong Academy in the residential area, but those residents still didn't believe it. How could anyone be willing to teach their skills to others.

However, it is said that an old gentleman can teach children to read. It costs only five Wen a month for shuxiu, which makes most residents with children excited. They ask Fang Jiming how to sign up and where to take classes.

Fang Jiming arranged for a hand to take charge of the matter, so he continued to publicize the news that Lu Qing was going to teach.

Even, he asked Ye Qiu to write a few leaflets and put them in a prominent position in the East and West cities.

Now the two markets have become prosperous slowly. Many Hu and Han people come here to sell things. Even many residents of Fulu County, hundreds of miles away, come to do small business.

On the day before the class, a guest came to Beidahe.

It's not Li Liang, the general of the Li family, but Zhang Shi's eldest son. Maybe it's better to call him lord now, because Liangzhou has actually become an independent country, and the year names are all in his own.

However, due to Zhang Shi's name as an assassin of Liangzhou still hanging on the surface, it was not good to directly enfeoffe his son, so he gave Zhang Dan a virtual post as governor.

When Zhang Dan came to Beidahe, the first thing naturally was to find yumingchuan to convey Zhang Mao's meaning. Zhang Mao said that now he was looking for talents from Liangzhou for Li Zhi. He wanted to tell her about the marriage. When it was settled, he sent someone to propose marriage in Hedong.

As for Li Liang, he has been sent to Wuwei County. There is a confrontation with Liu Han. He will hand over short soldiers at any time. Naturally, he has no time to manage his sister's children and girls.

Lu Qing snickered for a long time after hearing the news.

Sure enough, Zhang Mao, the old fox, understood what they meant and did a good job.

Therefore, yumingchuan's attitude towards Zhang Dan is much better.

"I won't go back so early this time. My uncle heard that Beidahe has reclaimed 10000 mu of good farmland and uses stone as fertilizer. He is quite curious. I'll see what's magical."

Zhang Dan was very polite to Yu Mingchuan, and he didn't have the airs of a prince at all. He was like a teenager of the same generation.

Although yumingchuan didn't give him a cold face, he was very defensive in his heart. Lu Qing was worried that they were constantly building Wubao. He didn't know what would happen if Zhang Dan knew.

After going back that night, the couple tangled about it in bed again.
