Chapter 289

Before ancient times, the word "rule" was used as two tools: rule and moment. Naturally, rule is a compass, while moment is a tool for drawing straight lines.

These two tools became the forefathers of ancient measurement.

Because of this, Xiao Ming doesn't need to think about how to produce tools like compasses and rulers, because Dayu already has them.

Now unified measurement is just an improvement, not a subversion.

So let Chen Wenlong take a compass and a ruler, and he will measure the size of millimeter. Comparing with the millimeter size in the science and Technology Library, he uses a compass to cross on the ruler. Every step of the compass is a millimeter. At this time, Xiao Ming points the next point.

When a compass finished walking one meter, he stopped, and then continued to draw vertical lines on it, specifying mm, cm, and marking.

In order to pursue your accuracy, he was busy for an hour before he drew this ruler perfectly.

At this time, he looked at the ruler in the science and Technology Library. Basically, there was not much error, but there was no way for him to deal with micron level error.

And now Qingzhou industry with his ruler is enough. After all, the machinery produced at this stage can not be error free.

After making the ruler, Xiao Ming gave it to Chen Wenlong and told him to produce it according to the standard of the ruler and apply it to all workshops in Qingzhou.

"Your Highness, is it really OK to change the weights and measures of Dayu?" Chen Wenlong is still used to the old weights and measures, so when he saw the ruler, he was a bit awkward.

Xiao Ming said: "it's not only a matter of weights and measures, it's a matter of industry. If Qingzhou's industrial products are produced with this precision size, it's not so easy for outsiders to imitate Qingzhou's products without using the same standard. Moreover, once the cutting tools are produced and the lathes are put into use, Qingzhou may have to produce more precision industrial products in the future, without this precision How to produce the size of, when the time comes, the lathe also needs the size of seal cutting. "

Chen Wenlong seems to understand, "it turns out that this is the reason. It's because the subordinate is stupid."

Then Chen Wenlong continued to ask, "Your Highness values this knife now. Will your highness have a new masterpiece?"

When Chen Wenlong mentioned this, Xiao Ming was shocked. Now it is the 18th century. In modern times, the West has eliminated the firerope guns and replaced them with flint guns. Now the state of Dayu does not even have a firegun or a shotgun. This is too big a pace to be pulled down. It is basically the same as that in the late Qing Dynasty when the West was driving a steamship, while the Qing Dynasty was still in the era of sail warships. "

Therefore, the reason why he is anxious about cutting tools is that once the lathe has qualified cutting tools, he will start to produce precision seamless steel pipe.

Yes, he mastered the technology of rolling iron to forge steel pipes, which can also be used to produce muskets.

But the production of guns, steel workshops, glass workshops and other industries had been stretched by slaves.

So at that time, he had to have a choice between the production of artillery or muskets. In the end, he chose artillery, because it was easier to produce artillery in technology, and the iron mold casting technology was enough to enable the rapid production of artillery.

At that time, the muskets had to be hammered and forged by craftsmen one by one. Even so, the ability at that time was only able to produce the muskets. In the battle of Cangzhou, the muskets could resist 100000 barbarian troops with hundreds of muskets at most. I'm afraid the muskets were not as effective as bows and arrows on the city wall, because according to the records, the trained muskets could fire 2 bullets every 3 minutes.

This deadly speed is also the reason why Xiao Ming didn't plan to produce the firearm. It's foolish to produce a kind of backward firearms when the western countries may have completely eliminated the firearm.

So his goal is to directly produce flint guns, shorten the generation gap of weapons, and not waste time to produce old weapons.

However, it can also be used, because once the suifa gun appears, it will inevitably cause the prying of all forces in the state of Dayu. At that time, it is also possible to push the rocket gun as a shield.

Although Xiao Ming now has this idea, the structure of the flint gun is more complicated. The barrel is only one of them, and there are springs and excitation structures that need to be made.

These two things don't have to be barrel simple at all.

In view of this, Xiao Ming did not answer Chen Wenlong's question. Instead, he let it go.

After all, Chen Wenlong is an official, not a technician like Chen Qi. It's useless to say more.

After giving orders for the production of cutting tools and moulds, Xiao Ming went to the palace. As soon as he went, it was noon.

When he passed Dongshi, he suddenly heard a familiar melody. When he heard the sound, Xiao Ming would smile. The aster is very efficient,.

This version of the white haired girl in the state of Chongqing is staged among the people.

"Zhao long, Zhao Hu, accompany me to have a look?" Xiao Ming asked with a smile.

During the last Spring Festival, Zhao long and Zhao Hu were not in the palace. Instead, they went home for the Spring Festival. When they learned that the drama in the palace was wonderful, they were looking forward to it.

What's more, they also heard the words at the front of the play. When they heard them, they immediately understood.

"Your Highness, is this the white haired girl?" Zhao long and Zhao Hu said happily.Xiao Ming nodded, "that's right. You didn't have a chance to see it when you went home for the new year. Now you can really enjoy it."

Two people smell speech, nodded.

After that, they walked to a stage in the east city.

The reason why Xiao Ming wants to join in the fun is not to relive the drama, but to see the reaction of the people. He can count on the white haired girl to spread to other vassal states through the folk.

Only in this way can his goal be achieved.

"My father can't buy my daughter's flowers if she has little money..."

When the three arrived, Xi'er on the stage was about to finish singing her own lyrics and surrounded many people on the stage to watch.

In such an era of lack of entertainment, there are too few entertainment items. Today, with the emergence of this kind of unique drama, people can't move.

"What kind of play is this? I've never seen it before

"Yes, the singing is strange, but it's very nice."

"It's said that this is Chen Chengzhen's troupe. They used to sing Liuzi opera, but now how can they sing it?"

“……”

Standing on the stage, the common people's comments spread to Xiao Ming's ears one after another.

On the stage, Xi'er finished her first song and began to enter the plot. At this time, the discussion of the common people stopped, but they were intoxicated in the performance of the drama. This kind of grounded drama made the common people quickly enter.

Xiao Ming never went to the theatre. At this time, Zhao long and Zhao Hu were also staring at the performance on the stage. In addition to the state of the people around him, he nodded slightly with satisfaction. It seems that this new type of drama is very promising to spread among the people.
