People in Datang have been expelled from school

Chapter 580 Accident at Yumen Pass

Li Lizhi looked at Li Zheng patiently guiding the little son to do the questions.

Wu Mei sorted out the accounts at the side, took a look and said, "Chang'an Ling is really a gentle person."

Li Lizhi said with a smile: "That's why you haven't seen him asking for money."

Wu Mei lowered her head and continued to sort out the accounts.

Li Yifu hurried over, "Ling Chang'an, Master Yan and Master Tie seem to have finished their work."

Seeing Li Yifu coming, Xiao Si said: "Brother-in-law, if you have something to do, you can do it first. Mingda can also ask Brother Huang and Sister Huang."

After speaking, Xiao Sizi ran into the house. Although Xiao Sizi was very sensible, she was also very shy of strangers, and basically did not show her face in front of strangers.

Li Zheng walked out of the house and said, "How is it?"

Li Yifu said, "Master Yan and Master Tie have already finished that thing, and it is now in the blacksmith's shop."

Li Zheng followed Li Yifu to the blacksmith shop, and there were many people here.

Yan Liben is directing a group of craftsmen to assemble.

Li Zheng stepped forward and looked at the two huge things in front of him. The front part of the rotary machine was cast by Tie Da with iron materials, and the second half was made by Yan Liben and these carpenters.

This rotary machine is also manual, not fully automatic.

However, it is more convenient to print than the current book printing house that needs to be molded continuously.

The drum-type rotary press is also the prototype of the printing press of later generations.

The drawings are still found in the system library. The printing speed of the rotary machine is very high, with an average speed of 50000 prints per hour, but this semi-automatic rotary machine should be able to reach a speed of about [-] prints per hour.

Yan Liben and Tie Da seemed to have some headaches with these things, and they didn't know how to assemble them.

Seeing Yan Liben's annoyed expression, Li Zheng stepped forward and began to assemble it under the eyes of everyone.

In the field of production, the application range of rotary machines is also very wide, such as die cutting and assembly line assembly.

The paper can be printed on one side by passing through an impression cylinder, as long as the cylinder is installed on the rotary machine.

That is more than ten parts.

After Li Zheng assembled all these parts, Yan Liben was still at a loss.

"Li Zheng, what are you all about?" Yan Liben couldn't help but asked.

"It's a semi-automatic device with good dimensional accuracy." Li Zheng looked at Yan Liben's expression. Yan Liben is very busy recently. After Li Shimin's other courtyard is built, he still needs to make this rotary machine. A new school will be built soon.

It's like there's endless work to do.

Li Zheng said to Yan Liben: "This is just a prototype. In fact, there are still many things that need to be built."

"and also?"

Li Zheng said with a smile: "The next thing is much simpler, Master Yan might as well rest for a few days."

After finishing speaking, Li Zheng beckoned to Li Yifu, "Order, one thousand guan for each."

A group of craftsmen were all laughing, a thousand pennies is indeed a lot of money.

Li Zheng said to everyone: "Go back and rest for a few days, you will still be busy in the future."

Li Yifu also said: "Everyone, follow me to collect the money."

Li Yifu took the people away, Yan Liben was still standing there, looking at the rotary machine in front of him, "Li Zheng, I still don't understand the relationship between this thing and printing."

Yan Liben really couldn't understand the ten-meter-long rotary machine in front of him.

Li Zheng explained: "Master Yan can be understood as web printing, have you seen the hook on it?"

Yan Liben nodded.

"Through the rotation of the handle at the rear, the paper is conveyed, and the roll paper is directly embossed out through the printing plate. Now our printing shop uses a single cycle, that is, one template prints one page, and the advantage of the rotary machine is continuous printing. In the printing process, the ink is on the semi-finished paper, and it is printed, pressed, and discharged from the rollers one by one, and the printing is completed."

Yan Liben's expression was a little twitchy, "The old man still hasn't understood."

Li Zheng explained again: "To put it simply, it is unwinding, printing, drying, and cutting. Basically, it is on one assembly line. We can save a lot of steps and save more labor."

Yan Liben still looked confused.

"Master Yan, let's go rest first. When the work is really finished, we will know what's going on. In fact, this is just a prototype."

Yan Liben nodded, "Maybe the old man is really too tired, the old man went to rest first."

Li Zheng looked at Tie Da on the side again, "You know what this is."

Tie Da shook his head and said: "The villain doesn't understand either. Although he doesn't understand, the villain knows that as long as there is something that he can't understand, it must be something very powerful."

You see what a simple sentence, what a simple truth.

In fact, this rotary machine is very large, its height alone is as high as a person, and its length is more than ten meters long.

This type of rotary press refers to the prototype of the industrial printing press of the later nineteenth century.

However, after the complete assembly line is built, the next factory building, paper raw materials, and construction are another very complicated issue.

Finally saw the progress.

Li Zheng asked Tie Da to recruit a few people to put the wheel loader in an idle granary in the village, and wait until the factory building was built before using it.

The boundary of Gaoling is still being reclaimed, and the old village head and a group of villagers basically spend a day here.

Picking up the hoe, Li Zheng also joined the team of reclamation.

The old village chief actually didn't like letting Li Zheng do farm work.

The magistrate is also the most promising child in Jingyang, how can he do this kind of rough work.

It's also a joke to say it.

But no one will stop Li Zheng from doing farm work.

When it was time for a break at noon, Li Zheng was eating a piece of cake and looking at the scenery in the field.

Li Yifu gave the craftsmen their wages, and came to say: "Chang'an Order Xu Jingzong has come."

Xu Jingzong also came running all the way, "Chang'an Order, something happened."

Li Zheng ate the cake without a bite, "What happened?"

Seeing Xu Jingzong panting, Li Yifu handed Xu Jingzong a water bag, "Drink your saliva first, and then speak after you have breathed."

Xu Jingzong drank water, calmed his breathing and said, "Something happened at Yumen Pass."

"Go on."

Li Zheng was eating the cake, and from a distance, he saw a group of officers and soldiers driving to Li Shimin's other courtyard. From here, he could see the situation of the other courtyard at a glance. It seemed that the news had also come from Chang'an.

Xu Jingzong lowered his voice and said: "After this Changsun Chong left Yumen Pass, he ordered a general to guard Yumen Pass. I don't know what happened. It seems that there was some conflict. As a result, the Western Turks who were stationed at first suddenly went to attack Yumen Pass. , Seeing that Yumen Pass is in chaos."

Li Zheng frowned and said: "How is the situation now? Didn't Chang Sun Chong mobilize a lot of soldiers and horses to go to Yumen Pass?"

Xu Jingzong shook his head, "I don't know what the situation is now, I should be able to hold the Yumen Pass."
