Rules, in ancient times, the word "rules" and "rules" were two tools. Rules were naturally compass, and rule was a tool used to draw straight lines.

These two tools became the originator of ancient measurement.

It is precisely because of this that Xiao Ming no longer needs to worry about how to produce tools such as compass and rulers, because it already exists in the Great Yu Kingdom.

Now unified weights and measures are nothing more than improvement, not subversion.

So, he asked Chen Wenlong to bring a compass and a ruler, and he measured the size of millimeters, compared with the size of millimeters in the technology library, and used a compass to cross the ruler. Every step of the compass was one millimeter. At this time, Xiao Ming pointed the next point.

When a compass finished walking one meter, he stopped, and then continued to draw vertical lines on it, clarifying millimeters, centimeters, and marking them.

In order to pursue your accuracy, he spent an hour working hard before he perfectly drew this ruler.

At this time, he looked at the ruler in the technology library. There was basically no error, and there was no way for him to have micron-level errors.

Moreover, the current Qingzhou Industry is enough to use the ruler he drew. After all, the machinery produced at this stage cannot be without errors.

After making this ruler, Xiao Ming handed the ruler to Chen Wenlong and asked him to produce according to the ruler's standards and apply the ruler to all workshops in Qingzhou.

"Your Highness, is it really okay to change the weights and measures of the Great Chongqing Kingdom?" Chen Wenlong was still used to the weights and measures of the previous weights and measures, so he felt a little awkward when he saw the ruler.

Xiao Ming said: "This is not only a matter of weights and measures, but an industrial problem. If Qingzhou's industrial products are produced in this precision size, it will not be so easy for outsiders to imitate Qingzhou's products without using the same standards. Moreover, once the tool is produced and the lathe is put into use, Qingzhou may have to produce more precise industrial products in the future. How to produce without such fine sizes, the lathe will also need seal carving sizes."

Chen Wenlong seemed to understand, "It turns out that this is the reason, because the official is stupid."

Then Chen Wenlong continued to ask: "Your Highness now values ​​this knife. Could it be that your Highness wants to have a new masterpiece?"

When Chen Wenlong mentioned this, Xiao Ming's heart suddenly felt a stir. It was now the 18th century. In modern times, the West had eliminated the flintlock gun and replaced it with a flintlock gun. Now the Great Yu Kingdom does not even have a musket or a bird gun. The step that was pulled down was too big, basically equivalent to the West driving a steamship in the late Qing Dynasty, while the Qing Dynasty was still in the era of sail warships."

Therefore, the reason why he was anxious about knives was that once the lathe had qualified knives, he began to produce precision seamless steel pipes.

That's right, he mastered the technology of forging steel pipes by coiling iron, which can also be used to produce muskets.

However, the production of artillery, steel workshops, glass workshops and other industries has made slaves short of it.

So at that time, between producing artillery or muskets, he had to have a choice. In the end, he chose artillery because artillery is more technically easier to produce, and iron mold casting artillery technology is enough to enable artillery to be produced quickly.

At that time, the muskets had to be beaten and forged one by one by one. Even so, their ability at that time was only able to produce a combroach. In the Battle of Cangzhou, he used at most hundreds of combroach guns to resist the 100,000 barbarian army. This combroach may not even be effective on the city walls as well as bows and arrows, because according to data records, well-trained combroach gun shooters can fire 2 bullets every 3 minutes.

This fatal speed is also the reason why Xiao Ming did not intend to produce a combroach. It is stupid to produce a backward firearm when the West may have completely eliminated the combroach.

So his goal is to directly produce flintlock rifles, shorten the generation difference of weapons, and not waste time producing outdated weapons.

However, this cowlin gun can also be used, because once the flintlock gun appears, it will inevitably lead to snooping by all forces in the Great Chongqing Kingdom. At that time, it is also possible to push the cowlin gun as a shield.

Although Xiao Ming now has this idea, the structure of the flintlock rifle is more complicated. This barrel is only one of them, including a spring, and the excitation structure needs to be manufactured.

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

In view of this, Xiao Ming did not answer Chen Wenlong's question, but called him and went there.

After all, Chen Wenlong is an official, not a technician like Chen Qi, so it is useless to say more.

After instructing the production of tool molds, Xiao Ming went to the palace. After a while, it was already noon.

When he passed by Dongshi, he suddenly heard a familiar melody. When he heard this sound, Xiao Ming smiled knowingly. Ziyuan was very skillful in doing things.

This version of the white-haired girl in the Great Yu Kingdom has been staged in the folk.

"Zhao Long, Zhao Hu, accompany me to see you?" Xiao Ming asked with a smile.

During the Spring Festival last time, Zhao Long and Zhao Hu were not in the palace, but went home for the New Year. When they learned that the drama in the palace was very exciting, the two of them were looking forward to it.

Moreover, the two of them also heard the words at the forefront of the drama, and when they heard them, they immediately understood.

"Your Highness, is this the white-haired woman?" Zhao Long and Zhao Hu said happily.

Xiao Ming nodded, "That's right, you went home for the New Year at that time and didn't have the chance to see it. Now you can really enjoy it."

When the two of them heard this, they nodded.

After saying that, the three of them walked towards a stage in the East City.

The reason why Xiao Ming wanted to join in the fun was not to relive the drama, but to see the reactions of the people. He could count on the white-haired woman to pass on the folk to other vassal states.

This will achieve his purpose.

"Their daughter has to spend money on my father and I can't buy it..."

When the three of them arrived, Xier on the stage had to finish singing her own lyrics and surrounded many people on the stage to watch.

They were all blinded. In such an era of lack of entertainment, there were too few entertainment projects. Today, with such unique dramas, the people could no longer move.

"What kind of drama is this? Why have I never seen it before?"

"Yes, this song is strange, but it sounds very nice."

"It is said that this is Chen Laoshi's opera troupe. He used to sing Liuzi opera, but now why do you sing this?"

“…”

Standing on the stage, the discussions of the people came into Xiao Ming's ears.

On the stage, Xier sang the opening song and began to enter the plot. At this time, the people's discussion stopped, but instead became immersed in the performance of the drama. This down-to-earth drama made the people quickly immersed in it.

Xiao Ming never watched the show. At this time, Zhao Long and Zhao Hu also stared at the performance on the stage. In addition to the status of the people around him, he nodded slightly satisfied. It seemed that this new type of drama was very hopeful to spread among the people.
