The whole family of villains criticized her wildly, but the princess treated her with medical treatm

"You're right."

Mu Tingxue couldn't help but glance at Yuwen Xiuzhu. This Beiyu proton had quite profound thoughts.

Isn’t that what modern society is like?

The marriage rate and birth rate are getting lower and lower, and the savings of three generations are spent on buying houses and cars. The final result is that young people who have received higher education are sober, and they even put forward the idea of ​​"I will give you leeks. "The seedlings are gone" and "the revenge of a slave is not to give birth to another slave".

"But, you are thinking a little too far. If we want society to develop to the stage you mentioned, there is still a long way to go. It will take hundreds of years to reach it. Let's think about something practical first, such as building more buildings. Build a school building to popularize education more, or add blackboards to every classroom."

"blackboard?"

Yuwen Xiuzhu looked confused, "What is that?"

"A teaching tool."

Mu Tingxue peeked into the classroom from the window just now, and her first feeling was - there was something missing, it didn't taste right.

A classroom without blackboard and chalk is soulless!

Blackboards were not widely used in schools around the world until the mid-[-]th century.In ancient times, teachers in private schools and great scholars in academies gave lectures orally, and once they heard it, they lost it.

There are so many extremely smart children, 90.00% of them are just ordinary people with mediocre intelligence.The teacher will tell you where to remember it.If there is a blackboard, students can take notes while listening to the lecture, and learning efficiency can be improved.

The blackboard can be made of cement or wooden boards.

Chalk is as simple as using lime. Just get a mold and you can mass-produce it by hand.

"To hang a blackboard on the wall, use cement first, then paint a layer of black paint on the outside."

Mu Tingxue had an idea in her mind and immediately put it into action.

The cement factory is in Baidizhou.When she returned to Yundu this time, she did not bring cement. There was no need to use cement to repair the Princess's mansion. She liked the antique architectural style.

The only way to get cement as quickly as possible is to find Yan Yang.

There is still a large amount of cement stored in the Zhenbei military camp.The Zhenbei Engineering Corps has completed the construction of cement roads leading to three salt-making plants, and is also preparing to use cement to build military campsite-style military dormitories outside the city, which are more spacious and comfortable than camp tents.

"Is Your Highness leaving?"

When Yuwen Xiuzhu saw her getting up to leave, a faint feeling of reluctance suddenly surged in his heart.

"Come back later."

Mu Tingxue didn't say much, and took a carriage straight to the Zhenbei Army camp.

*. *. *

The Zhenbei Army Camp is located at the foot of Yundu City.

Mu Tingxue has been here many times and is familiar with the roads.

Yan Yang's more than a dozen generals and generals, as well as school officers and sergeants at all levels, are all very familiar with the eldest princess. They treat her with respect whenever they see her, as if they regard her as their mistress.

"Where's the Regent?"

Mu Tingxue came to her fiancé's exclusive tent and looked around, but no one was there.

The glass on the table still had green leaves floating in it, and the tea was still warm.

"Shangzhuguo, he...well, he..."

The principal responsible for guarding the regent's camp had his eyes evasive and hesitant.

Mu Tingxue's bright eyes narrowed slightly: "What's wrong with him?"

Something must have happened.

The principal broke into a cold sweat and stood aside with his head lowered: "Shangzhu Kingdom is training troops in the west school field."

When Mu Tingxue heard that it was military training, she was not going to disturb him.

Supervising military training in Zhenbei is a job, just like going to the Hubu Yamen to handle government affairs.

So, she went straight to the warehouse of Zhenbei Military Camp.

With the tiger talisman in hand, the eldest princess can procure military supplies and weapons from the arsenal at will.

"Pack five hundred kilograms of cement."

"Your Royal Highness, what can you do with five hundred kilograms of cement? It's too little. You have to fill a cart at least."

"Enough is enough, too much is a waste."

It's just a blackboard. There are only three schools in total, and the total number of classrooms is no more than a hundred.Even if two large blackboards are built in one classroom, one steel plate trolley's worth of cement will not be used up.

Five hundred kilograms of cement were sealed, and two barrels of paint were taken.

The paint in ancient times was called lacquer, which was harvested from the lacquer tree. The lacquer turned black after being oxidized.Just perfect for painting the blackboard.

Mu Tingxue called about ten engineering soldiers and prepared to take them to the Imperial City Academy.

She doesn't know yet.

As soon as he left Yan Yang's camp, the elementary school guard on duty went to report the news.

Yan Yang was training at the west school field.

But at this moment, his brows were furrowed, his thin lips pursed tightly, and his whole body exuded an extremely cold aura.

Su Wanwan's eyes were as bright as spring water, and she held a purse with exquisite embroidery work in both hands and handed it over: "Your Highness the Regent, Wanwan used nine kinds of precious embroidery threads and spent three nights to embroider this with her own hands. Embroidered, given...given to..."

As he spoke, he blushed and lowered his head.

Yan Yang seemed not to have heard anything and walked towards the north with an expressionless face. He took down a red-tasseled spear from the weapons rack and continued to train.

Su Wanwan was treated like air, and her delicate body trembled slightly.

Since his father Su Shixing was seized power by Su Zixiu, the prince of Shenwei Hou, he resigned from the post of Commander-in-Chief of the Southeast Navy and took his concubine and favorite daughter with him to Yundu to take up the post of Guanglu Doctor.

Su Wanwan is the most favored daughter of the Su family. Even though she is a concubine, she has always been valued by her father, and her food, clothing, housing and transportation are all in accordance with the standards of a legitimate daughter.

Her father originally planned to pass the southeastern military power to her brother Su Zirang, but the unpopular legitimate son Su Zixiu hugged the eldest princess' lap, causing Su Zirang to lose the right to inherit.

The reason why she appeared in the Zhenbei military camp was to pester Yan Yang to give her purse.

It was because on the day when the regent led his army in triumph, the Su family's motorcade also happened to arrive at the gate of Yundu City.Su Wanwan was sitting in the carriage, lifting the pink curtain about a foot away, and saw the people of Yundu crowding the streets to greet the regent - his body was so tall and majestic, his outlines were delicate and sharp, and it was a picture that was enough to A handsome face that made women all over the city scream.

Su Wanwan fell in love with her at first sight!

After confirming her intention, she immediately took the initiative.

She is the daughter of the Su family. Her father and brother control 30 navy troops, while he is the head of the Yan family and controls 50 Zhenbei troops.These are the two largest military powers in Yunhuang.

Su Wanwan felt that she was very hopeful. She firmly believed that an ambitious and powerful minister like the Regent would not refuse a girl from the Su family to become a concubine!

If the Su family and the Yan family marry, then the regent can immediately get the support of the Su family's 30 naval troops. With the powerful alliance, from now on, he will be completely invincible!
