"Look at this, I specially designed it. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info called ......" Liu Mu didn't finish speaking, Dugu Lanruo said: "This is called Surprise Deer, there are many orchards in the Northern Dynasty There is this, which is used to prevent birds and beasts from harming the orchard." ”

"Okay. So what about this? Willow pointed to his little fountain.

Dugu Lanruo shook her head: "I can't think of why the water flows to a high place." ”

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

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

Qingheyu.

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

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

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

"Come, let my wife see the capital of arrogance for her husband." Liu Mu pulled Dugu Lanruo into his workshop in Qingheyu.

Dugu Lanruo was very surprised: "I only knew that you had a workshop in Turbidity River Valley, but I didn't expect that Qinghe Valley also had one." ”

"I asked the old wolf to take the gold medal given by the sage to scare the Sanyuan County Order, and then sealed all the roads on both sides of Qingheyu and Zhuoheyu, and only said that this is the place where the palace tribute is to be made."

Before arriving at the workshop, Liu Mu wrapped Dugu Lanruo tightly with a clean white linen, and then changed his clothes and took Dugu Lanruo inside.

"This is a seal?"

"It's not a seal, it's wooden, pottery, iron, copper, lead. Recently, several craftsmen of the former Sui Dynasty have restored a recipe from the Han Dynasty called white copper. This is called movable type printing, and the material of the characters is still being experimented with, which is a very money-burning place. ”

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

There were already arranged plates that were being tried to be printed, and the foreman's brows were twisted, and it was clear that progress was slow.

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

"Lang Jun, at the moment, we think copper, white copper, and lead are all good. But the difference is in the ink, we think that the ink should be glued, but what glue to add, how much glue to add is very difficult. We have tried pine, bamboo, and charcoal in ink materials, which is different from writing and is somewhat difficult. ”

The foreman looked ashamed, they were all craftsmen of the Great Sui court before, and their skills were extraordinary.

They were taken out of the coolie camp in Yangzhou, and they were fed, drunk, and clothed, but there was no real finished product in a month.

I can't help but be ashamed that I haven't made a jar of good ink.

"I remember what I said, there is no problem that cannot be solved by a carriage of copper coins, and if a carriage is not enough, another carriage will come. All I know is that this ink is for printing, and it must be good to use without fading. Then the difficulty is, the material of the printing plate, the formula of the ink, and the texture of the paper. ”

"That's what Lang Jun said."

"I don't know how to print plates, I don't know how to make ink, and I tell you about papermaking, cotton stalks are good. But maybe there are other good things, don't rush, let's try slowly. Before the New Year, whether it is paper, ink, or printing board, as long as there is one thing brilliant. You know, Silla was at war with Gogura. ”

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

Liu Mu smiled: "There is a city in Goguryeo that has been captured, and there are six thousand Goguryeo maidservants. Think for yourselves. ”

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

After leaving the workshop, Liu Mu asked Dugu Lanruo: "You say, can I tear the door valve?" ”

"No, it's not enough. Books are mostly in the gate, and your printing skills are very good, but what is the use of not having books to print. Even if you have a book to print, there will be a book in the market and a gate valve. ”

"Reasonable." Conception nodded: "So, let's look at the second one." ”

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

Second, Dugu Lan couldn't close her mouth in shock.

It was a yellow copper coin with a Tang-style princess on the obverse. In the Tang Dynasty, princesses of different status levels use different headdresses on formal occasions, this is a Lingyun bun, and it is a phoenix style.

There are only two princesses in Datang who are qualified to take such a head at the moment.

One is the eldest princess of Tong'an, and the other is Dugu Lanruo, the princess of Changpingxiu.

The relief on this copper coin is extremely clear and detailed, and it is obviously a young woman, so it can only be herself, and there is a row of small characters underneath, which must be seen carefully.

Commitment to mint money.

Looking at the back again, there are four words: two vertical and two molds.

Vertically is the word Changping, which looks like Li Shimin's flying white body, and then it is a text and two characters written horizontally in Lishu. If you look closely, there is still a row of small characters in the bottom circle, which reads Tang Wude in the seventh autumn.

"It's ......." If Dugu Lan is a little afraid, will she trespass if she does this.

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 in several critical positions.

"Brother Yan." Yanagi called out to a man who was busy working on the drawings.

Yan Liben.

Later generations know that this is a painter who has left a name for eternity, a famous painter. But who knows, Yan Liben is a good official, and Di Renjie was discovered by him and activated.

Of course, at the moment, Yan Liben's other talent is being used by Liu Mu.

Engineering.

Ge Liben, his brother Yan Lide, and his father Yan Bi were all first-class engineering masters. His brother was extremely accomplished in architecture, while Yan Liben was attracted by Liumu's super stamping machine, so he let Liumu turn here.

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

In the workshop, I saw several huge wooden wheels with a diameter of two zhang slowly rotating, one after the other. The final force was only applied to the tiny disc of the craftsman's table.

"Stop, readjust the third round." Yan Liben heard Liu Mu call himself, but he didn't look back, still paying attention to the hydraulically driven press.

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

"Graphite red copper bearings, and then dripping oil. I remember that there was a trial production in Yaozhou. Liu Mu asked puzzled.

Yan Liben shook his head: "I've also heard about that, it's easy to use but it's difficult to build, and it won't be able to make such a big one this year." Let's use it first, I don't think these things can only exert half the power without a good shaft. ”

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