The knife slowly passed through the copper piece, and the copper chips fell down in rolls.

Yang Yan was very serious and almost as if no one else was around.

Later he took a caliper made by Chen An to measure the size, and then another knife was made.

The last few parts that came out were polished and combined. Yang Yan pulled it and said, "It's very smooth."

“What about the gap?”

If the gap is too small, it will easily get stuck; if the gap is too large, it will be difficult to make deviations when pulling the crossbow machine.

The hand of using the crossbow must be stable. If the gap between the crossbow machine is too large, it will definitely not be accurate.

“Not big.”

Yang Yan handed the assembled crossbow machine to Chen An.

Chen An pulled left and right and said with satisfaction: "The gap is very small, just right."

"Is this a crossbow?"

Fu Bi frowned and said, "I have seen it, and it looks a headache, but he can easily create it alone. Is it the credit for this thing?"

He patted the earth machine tool and thought this thing was really ugly.

"Absolutely." Chen An said: "In the past, the construction of crossbows required one by one, which was a waste of effort, and it was not even possible for old craftsmen to build them. Now Yang Yan has created this machine tool, which requires only one person to operate, and it can continuously process the parts of the crossbows, and there is another advantage..."

“What are the benefits?”

"That's to exchange with each other..."

Chen An pointed at the several made crossbow machines beside him, and some students brought it to him.

"Disassemble and mix together."

Several crossbows were disassembled and the parts were mixed together.

"Prepare it!"

When assembled again, no one could find the parts of a crossbow just now, so they had to mix it up.

After the mixing and assembly, Chen An took it to check it out and it was correct.

He looked up and said to Fu Bi and Bao Zheng, "Do you two husbands know about this benefit?"

"Save trouble." Bao Zheng is not a warrior after all, so he can't say anything.

Fu Bi is also a two-knives. He picked up a crossbow machine and pretended to say, "Can you..."

Although he was a Privy Councilor, he didn't know anything about weapons at all. It was rare to know a crossbow machine.

So he pretended to study, but in fact he wanted Chen An to say it quickly.

"There are all kinds of things on the battlefield. For example, both crossbows are broken, but the broken places are different. At this time, you can exchange them and make one of the two crossbows together."

Do you understand this?

Fu Bi nodded and praised: "I have heard a lot of news about weapons being damaged in the Privy Council. Most of the sizes made by those craftsmen are different. They cannot be dismantled and repaired, so they can only be scrapped... This method is good."

The craftsmen process crossbow machines, of course the sizes of which are different, but the machine tools are different, even if they are just earth machine tools.

"This is just one of them," Chen An said: "The other advantage is... in the past, I had to cut things, but I could only use craftsmen to polish them slowly, but this bed could succeed at once... The things it processed were roughly the same in size, that is, as long as dozens of such beds were made, the energy source would be continuously built to create crossbow machines."

Chen An was happy in his heart and looked at Yang Yan with appreciation, and naturally praised him. "In the past, people built things one person had to cover from beginning to end, but with this bed it was different. The bed was cut into pieces, and the people below polished it according to the standards, and then assembled... That speed was so fast, and it also saved labor."

This is the assembly line of the Song Dynasty version!

As long as it is needed, the Song Dynasty can create countless beds and then create countless magical crossbows...

"Countless divine power crossbows are arranged in an array... When I think about it, I think Bianliang is as stable as Mount Tai, good! OK!"

Fu Bi said happily: "What if it is something else? It can be created?"

“A lot of things can do.”

Yang Yan was a little nervous and rubbed his hands, "It's OK to drill holes or chips."

"good!"

Fu Bi said with a flushed face: "I heard that you were concentrating on miscellaneous studies and didn't go to the imperial examination?"

Yang Di's blood was boiling outside the door.

The old Yang family is about to develop!

The prime ministers praised my son several times in a row. Is this going to be developed?

Yang Yan nodded, "Yes. Miscellaneous studies are endless. Students feel that they cannot explore clearly in their entire lives. They have no time to write poetry and articles..."

Fu Bi looked at him and asked seriously: "I am willing to be an official because of this?"

Yang Di was so anxious outside that he wanted to rush in, but two big men at the door were staring at him coldly. If he dared to step over the line, he would definitely kick him over.

Son!

Go to the imperial examination!

Go to the imperial examination!

Yang Di wanted to scream, but he was worried that he would anger Fu Bi and Bao Zheng. Then his son would not have any benefits, and he would lose someone.

"Yes."

Yang Yan said calmly: "The Attorney said that whether it is farming, doing business, or being an official, he should have some ideals. The ideal of students is to be strong and prosperous. The rise and fall of the world is the responsibility of every man."

"It's a strong and prosperous Song!" Fu Bi was in a daze, "I thought so and did it like this back then, but..."

They are just losers, now they are old. Looking at the young Yang Yan in front of them, Fu Bi couldn't help but think of his past.

At that time, Fu Bi was a tough guy. He would rather die than retreat when he negotiated with foreign affairs...

"At that time! There are so many opponents." Fu Bi smiled bitterly and said, "I am afraid. Now I am looking at you waiting for vitality... Anbei."

Shen An responded, and Fu Bi said, "Teach these young people well. The Song Dynasty needs young people who do not care about fame and fortune. Don't let them follow our old path."

Shen An glanced at him, "Yes."

Fu Bi and Fan Zhongyan jointly innovated the Song Dynasty, but eventually fell into trouble. Now in his late years, he can see young people set out again and want to make modifications to the Song Dynasty again. Fu Bi was very excited.

"I feel old when I see them." Bao Zheng also sighed a little, "Golden fat pill, Shenwei crossbow, what else is there in the future? I will wait and see. If I can make a good thing and have a rich appearance, what should I say..."

He looked at Fu Bi with a little provocation.

Fu Bi smiled and asked Yang Yan: "It's so good. I'm going to report this to the official family. It's just a trivial matter to come from a Jinshi."

Yang Di felt his legs were a little soft outside the door, his lips were trembling, but he couldn't speak.

Shen'an opens academy, but what should the students do?

Bao Zheng had been thinking about this question for a long time, but he was worried that he was alone and could not help but drag Fu Bi into the water, making him feel very happy.

"Okay, I'm also considered one of them!"

Yang Di slowly leaned against the door, his cheeks trembling, unable to believe that this was the prime minister of the Song Dynasty.

"Is this...is this my husband?"

The big man outside the door looked at him coldly, "What do you think?"

"My son, I agree! I agree quickly!"

The people inside were shocked by the shout. The two big men grabbed Yang Di and prepared to gaggle and drag it away.

"father."

Yang Yan rushed out, and Chen An shouted from behind: "Let him go."

Yang Di got free, and the first thing he did was to go in and salute, and then said flatteringly: "I have met two husbands and attendant, and the villain Yang Di... The son was young and ignorant, and the villain apologized for him."

"Dad."

Yang Di saluted, and Yang Yan couldn't help but get angry when he saw him so flatteringly.

Yang Di glared at him and looked up and said, "The son is ignorant, but he is ambitious in his studies, and he is honest and serious in his work... If he is an official, he will definitely not let down the official's kindness and the kindness of his two husbands... The villain will remember it for the rest of his life, and his descendants will remember it..."

He had met many officials in layman businessmen and knew how powerful these people were, so he smiled habitually, "If the dog dares to forget, the villain will break his legs..."

Don’t forget if others help you. Ten or twenty years, you will never forget your descendants. You must repay when you have the ability.

This is faithfulness!

People who have no faith cannot stand. People of this era are well aware of this and pass it on to their descendants as family mottos.

"Dad!"

Yang Yan's face turned red with anger.

The first idol of young people is mostly father, but the tall father used to be flattering at the two prime ministers, and he was very flattering...

Yang Yan was disappointed and even more embarrassed and upset.

But Fu Bi and Bao Zheng thought this was normal. Fu Bi smiled and said, "This matter is simple, just look at the back."

Bao Zheng said: "I guarantee this matter, so I will definitely not be wrong."
