Start Being a Vassal King Today - Chapter 230

[Chapter 230 Rules]

“Wait a minute, my father will go with you.” Wang Ying said.

Wang Chong jokingly said, “Dad’s iron cannon hasn’t been built yet?”

“Do you think Dad is half as good as you?” Wang Yingyou returned to a serious look.

He built eighteen gray iron cannons and white iron cannons that King Yan wanted, and it was time to report to King Yan.

The father and son arrived at the palace, and went into the study after the notification.

“Have you made the cannon?” Zhao Xu, who was still copying the textbook, was overjoyed when he heard this.

Wang Ying nodded, “As long as His Highness needs it, the Bing Zhan Division can manufacture white iron cannons in large quantities at any time.”

“Very good!” Zhao Xu said two words.

Through the monopoly, he did make a lot of money.

But once the monopoly rights are sold, they are gone.

In the future, he can only rely on the goods of the palace to make money.

But any goods will experience a process of rapid initial sales growth and gradual stabilization.

At this time, although the money was still coming in a steady stream, the income was basically stable.

If the four northern counties suddenly need large-scale expenditures, they may be stretched.

After all, if he wants the North Four Counties to catch up with the achievements of decades or even hundreds of years of development, he will have to spend a huge amount of resources in a short period of time.

This is the same as krypton gold in the game.

The solution to this problem is to continuously introduce new products.

Taken together, this amount is considerable.

For him, this low-profile version of the artillery is also one of the goods.

“Your Highness, I have lost.” Wang Ying said, and then Wang Chong said with a smile.

Zhao Xu is still in a good mood today.

So, he smiled and said to Wang Chong: “This king has expected it a long time ago, let’s talk about the spring steel problem?”

“How does Your Highness know?” Wang Chong asked in surprise.

Zhao Xuyu said to Wang Chong earnestly, “You still have a lot to learn. After the Science and Technology School is completed, you can come and listen to my lecture.”

“Yes, Your Highness.” Wang Chong’s eyes lit up. He has been looking forward to this matter , looking forward to the moon.

Now it’s finally time to start.

Then Zhao Xu told Wang Chong how to make spring steel.

Wang Chong was dumbfounded when he heard this.

“It’s that simple?” Wang Chong asked.

“Yes, it’s as simple as that.” Zhao Xu smiled.

In fact, the difference between ordinary steel and spring steel is a matter of “quenching and tempering”.

To put it simply, steel is forged into steel bars, and then baked in an ordinary furnace. This process is called medium temperature tempering.

The tempered steel bar will show the characteristics of hard inside and soft outside, and become elastic.

Not only Wang Chong, but also Wang Ying was dumbfounded.

He also didn’t expect that such a simple treatment could produce different steel.

From this, he thought that there seemed to be a lot of knowledge in this steel.

“Xiaguan is willing to admit defeat, and will concentrate on making firing devices from now on.” Wang Chong said obediently.

Zhao Xu nodded. Originally, he was just asking Wang Chong to take some snacks, but now his goal has been achieved.

However, in addition to the problem of materials, the manufacture of flintlock guns also involves a mass production problem like artillery.

The mass production of artillery was solved by iron mold casting.

But the flintlock has no such tricks as iron molds.

The only production method is assembly line production.

After all, it is estimated that it would take a month for a craftsman to independently build a flintlock from start to finish.

The assembly line only needs to manufacture the accessories and finally assemble them. ‘

However, in this way, the size standards of accessories have to be considered.

So he said to Wang Ying: “It’s just in time for you to come. This king will give you a more detailed measurement standard, and I will soon spread this set of measurement standards to the entire Yan County.”

“Measurement?” Wang Ying and Wang Chong looked at each other. One glance, waiting for King Yan’s next words.

Zhao Xu then explained to Wang Ying and his son what an assembly line is.

When the two heard the words, they suddenly realized, and at the same time they were very surprised.

They did not expect to be able to mass-produce flintlock guns through this method.

It does require a metric though.

“Meters, decimeters, centimeters, millimeters…” Zhao Xu picked up a pen and began to write on the paper.

While writing, he said: “What kind of measuring instruments are currently used by the military commander?”

“Rules, squares, and rulers.” Wang Ying said.

Zhao Xu nodded, gauges are compasses, which are used to draw circles, while moments are used to draw right angles, and rulers are lengths.

But these tools are not suitable for pipelines.

He felt that it was necessary to make a new measuring tool for Bingzhangsi, that is, a vernier caliper.

This is a high-precision measuring tool commonly used in contemporary manual work.

It is also a tool for checking workpiece dimensions.

With this, it is convenient to check the parts made by the craftsman.

But it was very difficult to make an accurate ruler in ancient times.

This is also one of the reasons why assembly line production could not be realized in ancient times.

But the question didn’t bother him.

He only needs one thing, and he can realize the contemporary scale in the four northern counties.

This is mercury.

Mercury is mercury, which was not difficult to find in ancient times.

To make a column of mercury, you need a closed glass tube in addition to mercury.

Now that Bing Zhansi has mastered the glass manufacturing process, blowing a glass tube is not a problem.

At that time, you only need to take a basin of mercury, take out the glass tube, fill it with mercury, and then buckle it upside down in the basin filled with mercury.

At this time, the mercury in the glass tube will drop, and a vacuum will appear.

The distance from the ground to this vacuum is 760 millimeters.

The reason is that the mercury column is used to measure atmospheric pressure.

At standard atmospheric pressure, the height of the mercury column is this value, and he also has the standard atmospheric pressure value of this area in his mind.

With this value, he can further subdivide it, let the craftsman divide the ruler evenly on the visual field of the naked eye, and get a high-precision ruler in Dasong.

Thinking of this, he explained the method to Wang Yingting.

The two fell into a daze again.

But after being sluggish, I am delighted. If I can get such an original ruler, Bing Zhansi will be able to polish fine accessories in the future.

“You guys prepare the things first, and I will personally participate. When the first original ruler is made, I will teach you how to make a vernier caliper.” Zhao Xu said lightly.

He didn’t do this before because the Bing Zhansi didn’t use such fine things.

But it will be different in the future.

Not to mention the flintlock, grinding tools such as drill bits also requires high-precision measurement.

With these high-precision things, the next step is to produce more compact machinery.

Otherwise it’s all bullshit.

“Yes, Your Highness.” The two agreed yes.

Nothing else to do, the two bid farewell to Zhao Xu.

After leaving the study, Wang Ying and his son looked at each other and shuddered at the same time.

Now what King Yan taught them is really beyond their comprehension.

Then they sighed at the same time, the two shook their heads and left, ashamed of themselves.

study.

After Wang’s father and son left, Zhao Xu sent someone to call Chang Wei.

He has an urgent matter that needs to be entrusted to him.
