Tang Dynasty good brother-in-law

Chapter 253 Changping Money

"Look at this, I specially designed it. It's called..." Before Liu Mu finished speaking, Dugu Lanruo said, "This is called Jinglu. There were many orchards in the Northern Dynasties that had this to prevent birds and beasts from harming the orchard."

"Okay. What about this one?" Willow pointed to his small fountain.

Dugu Lanruo shook her head: "I can't figure out why the water flows to high places."

"Haha, let me tell you, there has been a technology called siphon since the Han Dynasty..."

For five days, Liu Mu and Dugu Lanruo did not leave the manor, until five days later, when the servants, maids, and maids sent by the palace arrived, Liu Mu and Dugu Lanruo were not in the manor.

Qinghe Valley.

"Husband, you shouldn't refuse the Zheng family's overture."

"Little Zheng's family, I can cripple them in a few days." Liu Mu said endlessly.

Dugu Lanruo sighed slightly: "Husband, don't be arrogant."

"Come on, let my wife see the capital of her husband's arrogance." Liu Mu dragged Dugu Lanruo into his workshop in Qingheyu.

Dugu Lanruo was very surprised: "I only know that you have a workshop in Zhuohe Valley, but I didn't expect Qinghe Valley to have one."

"I asked the old wolf to take the gold medal given by the sage to scare the Sanyuan county magistrate, and then sealed off all the roads on both sides of Qinghe Valley and Zhuohe Valley, and only said that this is the place where palace tributes will be made."

In front of the workshop, Liu Mu wrapped Dugu Lanruo tightly with a clean white linen cloth, and then he changed his clothes and brought Dugu Lanruo inside.

"Is this a seal?"

"It's not a seal. Wooden, pottery, iron, copper, and lead are chosen here. Recently, several craftsmen in the former Sui Dynasty restored a formula in the Han Dynasty called white copper. This is called movable type printing. Now the word The materials are still being tested, and this is a very expensive place.”

Liu Mu took Dugu Lanruo to another room in the workshop.

There are already arranged plates that are trying to print, the foreman's brows are wrinkled, and it is obvious that the progress is slow.

"Don't worry, just succeed next year." Liu Mu comforted.

"Lang Jun, we think that copper, white copper, and lead are all good materials. But the ink is bad. I think glue should be added to this ink. It is very difficult to add what kind of glue and how much glue to add. We have to try the ink material. Over pine, bamboo, and charcoal, this printing is different from writing, and it is somewhat difficult."

The foreman looked ashamed. They were all craftsmen of the Sui court before, with extraordinary skills.

They were picked up from the coolie camp in Yangzhou, and provided with food, drink and clothes, but there was not a single real finished product in a month.

I can't help being ashamed that I didn't even make a jar of good ink.

"Remember what I said, there is no problem that a cart of copper coins can't solve. If a cart is not enough, another cart is needed. I only know that this ink is used for printing, and it must be easy to use and not fade. The difficulty is, The material of the printing plate, the formula of the ink, the texture of the paper."

"Lang Jun said so."

"I don't know printing plates, and I don't know how to make ink. Let me tell you about paper making. Cotton stalks are good. But there may be other good things. Don't worry, let's try slowly. Before the New Year, whether it is paper, ink, or printing As long as there is one good one. As you know, Silla and Goguro fought at each other."

The craftsmen couldn't understand what war had to do with them.

Liu Mu chuckled: "A city in Goguryeo was captured, and there were six thousand Goguryeo maidservants. Think for yourself."

After speaking, Liu Mu pulled Dugu Lanruo and turned to leave, leaving behind all the craftsmen who were stunned.

After leaving the workshop, Liu Mu asked Dugu Lanruo: "Tell me, can I tear apart the gatekeepers?"

"No, that's not enough. There are many books in the aristocracy, and your printing skills are extremely good, but what's the use of having no books to print. Even if you have books to print, the market has books, and the aristocrats will have them."

"That makes sense." Conception nodded: "Then, let's look at the second one."

Dugu Lanruo was very surprised, her husband was determined to fight against the powerful.

The second thing is that Dugu Lanruo couldn't close her mouth in shock.

It was a bright yellow copper coin with a Tang style princess portrait on the front.In the Tang Dynasty, princesses of different status levels used different headgears on formal occasions. This is the Lingyun bun, and it is the phoenix style.

Datang currently only has two princesses who are qualified to make such a head.

One is Princess Tong'an, and the other is Dugu Lanruo, Princess Changpingxiu.

The relief on this copper coin is extremely clear and the lines are meticulous. It is obviously a young woman, so it can only be me, and there is a row of small characters underneath, so you can see it clearly.

To cast money.

Looking at the back, there are four characters in two vertical lines and two moulds.

Vertically there is the word Changping, which looks like Li Shimin's Feibai script at first glance, and then there are two characters written horizontally in official script.If you look closely, there is still a row of small characters in the bottom circle, which says the autumn of the seventh year of Tang Wude.

"This..." Dugu Lanruo was a little afraid, whether she would overstep if she did so.

Liu Mu didn't answer, but took Dugu Lanruo into a workshop, which was heavily guarded, and there were beds and crossbows in the dark at several important positions.

"Brother Yan." Liu Mu called to a person who was busy with the blueprint.

Yan Liben.

Later generations know that this is a painter who has left his name through the ages, a famous painter.But who knew that Yan Liben was a good official, and Di Renjie was discovered and employed by him.

Of course, another talent of Yan Liben is currently being used by Liu Mu.

engineering.

Ge Liben, his elder brother Yan Lide and father Yan Bi are all first-class engineering masters.His elder brother has extraordinary attainments in architecture, and Yan Liben was attracted by Liumu's super punching machine, so he let Liumu come here.

The side portrait of the princess on the copper coin was painted by Yan Liben himself.

In the workshop, several huge wooden wheels with a diameter of two feet were slowly turning, one inside the other.The final force only acts on the small disc on the craftsman's table.

"Stop, and readjust the third wheel." Yan Liben heard Liu Mu calling him, but he didn't turn his head, still focusing on the water-powered punching machine.

Yan Liben turned around when the craftsmen over there started working: "Let me tell you, this method needs to be changed, and the key lies in the shaft. Whether the transmission part is a belt or a steel tooth, the problem of the shaft will not be solved. It will take less than half a month to replace the shaft."

"Graphite red copper bearings, and then drip oil. I remember that there is a trial production in Yaozhou." Willow asked puzzled.

Yan Liben shook his head: "I've heard about that too. It's easy to use but hard to make, and we won't be able to make such a big one this year. Let's just use it first. I think these things can only play half of their power without a good shaft."

"You think I don't want to." Liu Mu handed Yan Liben a cloth to wipe his sweat: "I wish I could build a guy that can fly in the sky tomorrow, do you think it's possible?"
