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

The regent rushed to the military supplies warehouse as quickly as possible.

Sure enough, I saw my fiancée commanding ten engineering soldiers to transport a batch of cement and paint.

In her own hand, she held a basket of chalk soil.

Yan Yang stepped forward and asked, "What other wonderful ideas have you come up with?"

Seeing the eldest princess's attitude of doing something big, he knew that she was going to do something new again.

When Mu Tingxue saw a thin layer of sweat on her fiancé's forehead, she understood that someone had tipped him off and he had run all the way from the military training school.

"Making chalk."

"What is chalk?"

There was no ready-made chalk in Mu Tingxue's Cangbi Vase space, so she could only tell the truth: "You will know when it is made. But before that, I want to borrow your arsenal or ordnance factory to help me create it. Two molds.”

"no problem!"

Yan Yang readily agreed, "The military factory is nearby. The ordnance is located in the city."

To be precise, the military factory is a small town.

The best blacksmiths and weaponsmiths in the world were recruited, and they were forged in countless kilns day and night.

This extremely large arsenal is controlled by the regent.He not only controls the world's arsenal, but also controls the world's iron weapons.

Salt and iron are heavily taxed, and private weapons are not allowed to be made privately. Once discovered, it will be a crime of rebellion.Even the number of bows and arrows used by hunters needs to be registered with the local county government and recorded.

"The mold is not complicated. Just wait a moment and I will draw it."

Mu Tingxue took the pen and paper from her fiancé, and after three strokes, five divided by two, she finished the drawing.

"Somewhat like a honeycomb."

Yan Yang looked at the things on the drawings. The paintings she drew were very realistic and three-dimensional. They were completely different from traditional landscape paintings, with "hundreds of holes."

Mu Tingxue said: "Just let the military factory be restored to the same proportions. I've marked the length and width."

Half a day's work.

The military factory made the chalk-making tools that Mu Tingxue wanted.

It is a rectangular parallelepiped with about [-] circular holes densely packed inside, and under each hole is a thin cylindrical shape the size of a chalk.

"Crush chalky soil into powder."

Mu Tingxue does not need to do the breaking steps herself.

Yan Yang was very diligent and fetched a grinder and a mortar: "Are you talking about the Guanyin soil in the basket?"

The soil of Guanyin soil is relatively soft, so it was ground into white powder without any effort.

"It turns out this is the Guanyin soil that people eat during times of famine."

Mu Tingxue was a little surprised. She only knew that it was the main raw material for making chalk. Its chemical name is chalk soil. It is widely distributed in hilly areas and sandwiched among the rock formations on the mountains. Its main component is calcium carbonate.

"Ah."

Yan Yang has never eaten it, but he has heard that "when the army builds camps, it is sometimes used for painting. In the past few years, the army's food and salary were not enough, so some soldiers would eat a little when they were very hungry."

Mu Tingxue said: "You must not eat it anymore. The body cannot absorb this kind of Guanyin soil. It will make people feel full. Eating too much will cause constipation, indigestion, and death from bloating due to hunger. "

Yan Yang looked at her with much gentler eyes, no longer as fierce as before: "You exchanged potatoes for so much military pay, and there will no longer be hungry soldiers eating Guanyin soil."

Guanyin soil, which is powdered chalk soil, was ground out by the Prince Regent.

Mu Tingxue added a little more gypsum, which has the effect of accelerating solidification.

Then, pour the powder into a wooden barrel, add an appropriate proportion of water, and stir.Then pour into the chalk grinder.

Use a thin wooden board to scrape the white slurry floating on the grinding tool into another spare bucket.

Less than a quarter of an hour.

"Solidified."

Yan Yang was surprised to find that the white slurry in the mold turned into a white solid.

Mu Tingxue turned the chalk grinding tool upside down, placed it on the bamboo table and knocked it gently. A total of four hundred white chalks fell out of the round holes of the grinding tool.

"Put it on the bamboo board and let it dry for a while."

The October sun was not bad. It didn't take long for the chalk to dry and become hard.

At noon, Mu Tingxue asked the engineering soldiers to build a blackboard on a prominent wall in the Zhenbei camp, somewhat similar to a bulletin board.

It has also solidified and dried in the shade at this time.

She took out a piece of white chalk and wrote on the blackboard of the military camp's bulletin board - Root out evil and protect the country.

Yan Yang looked at the small piece of white chalk, glowing with magical power in her hand. First she wrote an inspiring slogan, and then, with a few random strokes, she sketched some lines in the lower right corner of the blackboard. Mountains, rocks, water.

After a while, it became a picture of a thousand-mile country!

The picture is not very detailed, but at first glance, it is particularly shocking!

Mu Tingxue drew the first issue of Zhenbei Army's blackboard newspaper on the spot. On the left side, he wrote vertically: The motherland is in my heart.

In the middle, there is a commendation column: a list of special military merits, first-class military merits, second-class military merits, third-class military merits, and the best soldiers of each month.

Yan Yang was completely dumbfounded. The names of these people with military merits were on the blackboard. Doesn't this mean that they were hung in the most conspicuous place every day and that the entire army was constantly reporting praises?

After a while, many soldiers gathered in front of the blackboard.

"Does it have my name? I can't read."

"Yes, you are a third-class meritorious officer. The names of Mr. Qin Xiaohou and the Prince Regent are at the top."

"Hey, you have such a long face! It would be great if I could also read."

"I want to go to the blackboard too!"

……

Mu Tingxue pointed to another blackboard and said, "We can organize it and use chalk to write on the blackboard to teach the illiterate children how to read."

Literacy is always good.

Yan Yang understood her intention and praised: "You made the chalk mainly for use by Mr. Jiaoyu from the Imperial City Academy."

Mu Tingxue said: "The cost of chalk is very low, and it can also be used by students who cannot afford pens, ink, paper and inkstones."

She took out a half-meter wooden blackboard.

I wrote his and my own names, and then circled them carefully.

Yan Yang's pupils shrank and his heart beat wildly: "Don't wipe it!"

Unfortunately, it's late.

Mu Tingxue had already taken a rag and wiped it off: "After wiping it clean, you can continue to write. You can write as many words as you want, saving money on paper and pen. If you are not satisfied, you can erase it immediately."

Yan Yang stared at the rag and pursed his thin lips.

He is satisfied!

Very satisfied!

He picked up a piece of chalk, wrote the two people's names on the small wooden blackboard again, and circled them carefully.

The corners of his lips were slightly upward again.

Mu Tingxue couldn't help laughing. She looked at her fiancé and remembered a sentence: A man will remain a boy until he dies.

"Are there any mines nearby that are rich in chalky soil?"

"Yes, there is a Guanyin Mountain two miles east. The mountain is covered with Guanyin soil."

"Okay, let's build a chalk factory there."

Because of the chalk manufacturing process, it is very simple and only requires a large number of molds.With Guanyin Mountain as your back, you can eat the mountain as your back.

In just three days, the chalk factory recruited a group of workers and started production.

One mold can produce four hundred pieces of chalk in less than a quarter of an hour.Mu Tingxue asked the Ordnance Factory to rush out a thousand molds, five hundred of which were used to produce the cheapest white chalk.

The remaining five hundred are used to produce colored chalks.Just add ancient dyes to the raw material liquid.

The old rule is to focus on both the low-end market and the luxury market.

white chalk, a penny a box, a hundred sticks each;

Colored chalk, ten cents a box, with ten colors to choose from;

Hagoromo's dust-free chalk is coated with a thin layer of glaze so that no dust will fall off when writing. It costs ten taels of silver per box, making it one of the most affordable luxury items.

Dust-free chalk carving, chalk carving roses, chalk pagodas, chalk carvings of auspicious animals, chalk carvings of famous paintings, and sealed with thin glaze, the colors have been increased to fifty kinds, 100 taels of silver per box.It’s the Rolls-Royce of chalk!

The goods are ready.

The next step is to prepare for the opening of the Imperial City Chalk Shop. The store was chosen by Yan Yang.

"You're not going to hang this in the center of the shop to show your affection, are you?"

Mu Tingxue felt a little ashamed when she looked at the small wooden blackboard with their names written on it and hearts painted on it.

Yan Yang raised his eyebrows: "Yeah."

"Ahem, it doesn't quite fit..."

"very suitable."

He just wanted to show it to everyone in Yundu, including those who coveted his wife and the woman named Su.

"Otherwise, you can take it off. I'll use colored chalk to draw you a bigger and better confession on the blackboard."
