Zheng Zhou thought carefully and asked, "Qin Lang, when will I notify my family?" ”

"How many people are in your family?"

"There are three of them, and there is a son and a daughter in the family, who are taken care of by the eldest brother."

Qin Mu nodded, "Eldest brother? What does it do? ”

"My eldest brother mainly helps people repair houses in Luoyang, such as repairing leaks, repairing stairs, paving roads, etc., and doing some miscellaneous work."

Qin Mu crossed his fingers with his mobile phone and pondered for a long time.

Ancient architecture was originally the pinnacle of craftsmanship, and some of the carts before the horse were replaced by the current reinforced concrete.

"Then he knows how to cast a mold?"

Zheng Zhou scratched his head and asked, "Most of these inverted molds are used for gold and copper, but very few are used for architecture, not that they can't, but the manpower carving is more beautiful." ”

Although the manpower carving is exquisite, it is too time-consuming, and it takes too much manpower and material resources to reproduce it on a large scale.

Take the ancient tombs of the past dynasties, each tomb has a stone statue standing on both sides of the Shinto road, and their manufacturing process is mostly stone carvings, and its exquisiteness can be said to be lifelike.

It was not until the middle and late Qing Dynasty that the stone statues poured out of cement were born.

"Well, I know what to do, so you recently contacted your eldest brother and asked him to go back and find the lime, and then I wrote a recipe for him to go out and give it a try."

Zheng Zhou's face was full of doubts, "What is this going to do?" ”

Several others said.

"Don't ask, what Qin Lang tells you to do, you can do it."

"Steal the fun, some of us are going to be executed soon." Wang Xiao of the Ministry of Officials squinted at Li Qingsheng of the Criminal Department and said.

Li Qingsheng pretended to be calm, "I'm not like you, I completely believe in Qin Lang, he must have his intentions in doing this." ”

He was born in a big family, but his ancestors were given the surname by Emperor Taizong, and now that Empress Wu is in power, Emperor Taizong's grandsons will not be spared, not to mention that he is a prisoner who has been disconnected from the family, and his hope can only be pinned on Qin Mu.

Qin Mu has a lot of knowledge in his head, he likes these popular science and manufacturing videos when he goes to work and fish on weekdays, and since he has experienced torture, these memories have become clearer and clearer.

In addition, he also has a lot of e-books and other things in his mobile phone, which is something to read for fun when camping in the wilderness.

Looking at the phone, Qin Mu remembered that his power bank needed to be charged.

Take a small solar panel out of your bag and place it in the small window of the cell to charge it.

These things are all necessary for camping, but the main reason is that he doesn't want to spend money to go to the hotel to charge his power bank and other equipment.

A 100,000 mAh power bank, flushed with a solar panel, at least more than half a month to be charged.

As long as the board is not broken, his phone will always be charged.

Zheng Zhou suddenly thought that he still had eight days left in his sentence, so he eagerly asked Qin Mu, "When can I get out?" ”

Qin Mu glared at him and replied, "Then it depends on whether your eldest brother is interested or not, if he can't make what I asked for in a day, then you don't want to go out for a day." ”

As a person from the Ministry of Industry, he must make cement that can impress the martial arts, and it is roughly estimated that it will take at least a week.

Qin Mu took out the banknote and handed it to Zheng Zhou, "I said you write." ”

Zheng Zhou didn't slack off, picked up the pen and stared at Qin Mu with big eyes.

"Lime, clay, iron ore, according to a certain ratio of the fine, grinding into powder, and then put into the cave, drying to remove water, and then grinding again to form flour, grinding process repeated more than three times, each time mixed with water solidification after testing the hardness, to be almost the same as the stone to be considered a success." Qin Mu said slowly.

Zheng Zhou took the pen and looked at Qin Mu in surprise, "What is this?" ”

"It's called cement."

"Cement?"

Others listened to the ingredients and methods as if they were making porcelain or something, and the name was like a child's living mud and playing at home.

Can this thing save people?

"Can this so-called cement save my life?" Zheng Zhou was a little hard to believe, and more than that, he didn't understand.

Qin Mu smiled slightly, "Of course that's not enough." ”

Then he took out a pen from his bag and used his mobile phone as a ruler to draw a pattern.

"With this, you won't have a problem going out at all." Hand the paper to Zheng Zhou, "Take it to your eldest brother first, let him make this thing at any cost, otherwise, I won't be able to save you." ”

The others looked at the image on the paper with their heads hooked, and for a moment they couldn't recognize what it was.

Zheng Zhou took two pieces of paper and ran to the door of the cell in a hurry, his head squeezed into the crack of the door and shouted: "Brother jailer! Jailer brother! ”

This is Qin Mu's maximum, he just knows the production technique, as for the fine proportions, he can't do anything, interlacing is like a mountain, everything is left to professionals to explore.

Zheng Zhou and the jailer agreed on the price, and the jailer agreed when he saw that the content on the paper was not prohibited.

Zheng Zhou sat down in front of the cell door with a relieved sigh of relief, a smile of salvation on his face.

Inside the Lichun Palace.

Empress Wu sat at the desk and carefully studied Yu's advice today.

At this time, Shangguan Wan'er came to the desk with a tray and really came with a cup of tea.

Empress Wu put down the paper and suddenly asked, "Wan'er, do you think this deflation will happen in my Datang?" ”

Shangguan Wan'er put the tea in front of Empress Wu, straightened her posture and replied: "Wan'er grew up in the palace since she was a child, and she has little contact with the common people, and rarely uses coins, gold and silver to buy things. ”

Empress Wu nodded slightly, most of the people in the palace were from famous families, and they had long been separated from the people, and many things could not be judged accurately.

It can directly obtain the demands of the people and directly recruit talents from all over the world for their own use.

"However, Wan'er knows that once the coins are in the hands of a few people, there will be extreme exploitation, and they must not be degraded to thousands of years ago when bartering was carried out."

Empress Wu's brows furrowed with a little helplessness, "It's a trouble to mint too few coins, and if you make more coins in the future, it's not worth it, it's a big trouble." ”

She knew in her heart that most of the coins produced went to the hands of officials, families, and squires and landlords, and the coins of the Tang Dynasty were for the people of the Tang Dynasty, not stored and rotten in the treasury.

"Although my Datang is prosperous, there are many more crises behind this prosperity than imagined.

Now the Shaofu Supervisor will let all localities make money every year, but the effect is very small, and it has been delayed again and again, in the final analysis, there is still a lack of red lazuli and a manpower-saving manufacturing process.

And that group of corrupt officials who are crazy about accumulating money! ”

The more Empress Wu spoke, the more angry she became, and her tone became heavier and heavier.

"Why don't you make coins out of paper?" Wan'er said suddenly.

Empress Wu smiled disapprerovingly, "Wan'er, this paper is okay for calligraphy, writing and painting, but it is not only easy to be damaged when making coins, if it is counterfeited by people with ulterior motives, how can ordinary people distinguish it?" If you print too much, you may not even have enough paper in the end. ”

She looked at the paper on the table again and asked, "Wan'er, read the contents of this paper." ”

Shangguan Wan'er read it carefully, with a puzzled expression on her face.

"This way of writing is very strange, and a lot of it is verbal, is the Queen Mother suspected that the content was told to Yu by others?"

"Let's just wait."
