Dai Zi really didn't expect that Taichang would ask him if he would make money by selling paintings.

This can be said to be his family's business, so he naturally knew it very well.

Question: Is he a candidate of this class okay? Moreover, his answer sheet does not mention selling paintings, he is talking about the continuous bead gun!

Why did the emperor ask this?

He was stunned for a moment before carefully explaining: "The emperor, the student's father once said that gold and silver in troubled times, and antique calligraphy and paintings in prosperous times.

Now the Ming Dynasty is in a rare prosperous era, and these calligraphy and paintings must be very valuable.

However, if this painting is sold at a high price, it must not only be well drawn, but also be famous.

When my father was a scholar, the paintings he drew were not very valuable, and usually only cost a penny of silver.

However, after my father passed the imperial examination, the paintings he drew were valuable, and a painting could be sold for a few taels of silver.

Later, my father joined the disciple of Xie Bin, a famous painter in Jiangnan, and the paintings he drew became even more valuable.

Now my father can sell at least a few dozen taels of silver for a painting. It is very good to paint it, and it is possible to sell hundreds of taels."

Antique calligraphy and painting in prosperous times?

Well, only people have the leisure to collect antiques and appreciate calligraphy and paintings in the prosperous times. Antiques calligraphy and paintings in the troubled times are indeed worthless.

If a painting can sell at least dozens of taels of silver, then the magistrate is indeed boring.

Because the magistrate's salary for a month is not even a few dozen taels of silver.

This at least proves that Dai Zi's father was a honest official.

If you are a corrupt official, it will be different. After three years of Qing Dynasty magistrate, he has 100,000 silver silver and a nonsense painting!

As the saying goes, like a father, like a son, and this kind of character should be fine after a clean official.

Taichang nodded slightly, then asked again: "Do your father still like to study muskets?"

This one doesn't.

Dai Zi Lao said honestly: "Your Majesty, the student's father is just obsessed with painting, and he is also interested in mechanical equipment. The musket student's father has never studied it."

Taichang couldn't help but say curiously: "Who did you learn the skills of your musket?"

This is a long story.

Dai Zi thought about it carefully before explaining: "Your Majesty, the students have been studying with their father since childhood and are also interested in painting and mechanical equipment, so the students choose science.

Five years ago, when the student took the provincial examination, he did not pass the exam because he was young and did not do a good job in writing.

However, at that time, several mentors from the Jinling Academy of Sciences took a fancy to the students and deliberately left the students to teach them carefully.

After entering the Jinling Academy of Sciences, students occasionally saw Master Bi's masterpiece "Military Arts Pictures" and became very interested in muskets.

In recent years, students have been studying the skills of muskets while studying. Several mentors have also strongly supported them and collected various muskets for students.

Gradually, the students also gained some experience.

Then the students began to think about the bead gun."

It turns out that the genius trained by the Jinling Academy of Sciences.

very good!

Taichang couldn't help but feel relieved: "I will give you a lot of rewards to write down the names of your mentors!"

Dai Zi hurriedly bowed and said, "Thank you for your grace, the emperor."

Taichang nodded slightly, then asked again: "Have you tried this continuous bead gun?"

Uh, this one.

Dai Zi said awkwardly: "Your Majesty, because there are no precision machine tools at the Jinling Academy of Sciences, many parts cannot be processed. The students made a wooden model and tried it. The real student of the bead gun has not yet made it."

This is simple.

Taichang thought for a while, then said aloud to the door: "Cheng'en, please call Meng Hou and Chuyang over. In addition, he ordered people to prepare the Feilong warship. I want to go to Wubei City."

Wang Chengen outside the door quickly said respectfully: "Abide by the order."

Taichang smiled again and asked, "By the way, have you ever taken the words?"

Dai Zi hurriedly bowed and said, "Your Majesty, the student's name is Wenkai."

Taichang nodded slightly, then raised his hand and said, "Wen Kai, come here, I will tell you about the bullets and magazines."

Bullets and magazines?

Dai Zi couldn't help but look confused when he heard this.

Of course he knows what the bullet is, what the problem is, what is the magazine?

At this time, Taichang had already picked up his pen and started drawing on the paper.

Seeing this, Dai Zi quickly came over carefully and looked carefully.

Taichang explained: "Wen Kai, look, this is the magazine, that is, the bullet bag drawn on your answer sheet.

The bag character is not vivid, because the one that holds bullets is also a metal shell, so it is more vivid with a magazine."

Oh, it turns out that the magazine is a bullet bag.

The emperor didn't explain that he really didn't know what the emperor was talking about.

Taichang has no painting skills. What he draws is an abstract picture, which is just a rough appearance.

However, this is not the point.

Immediately afterwards, he drew a few lines at the bottom of the magazine and explained: "Look, you can add shrapnel or springs under this magazine to push the bullet upwards.

In this way, you can easily bring the bullet into the barrel by simply setting up a movable snap above the magazine and connecting it to the trigger."

Shields and springs?

When Dai Zi heard this, he couldn't help but ask excitedly: "Master, what is a spring? Is it similar to a shrapnel effect?"

He knew about shrapnel because the flintlock rifle trigger device had shrapnel, but he had never seen the spring before.

Taichang nodded slightly and said, "Well, the effect of springs is similar to the shrapnel, but the spring is stronger and more durable than shrapnel.

As for what the spring looks like, you will know it when you see it."

When Dai Zi heard this, he couldn't help but say happily: "Students understand."

He was a little worried that the device that took the bullet out of the magazine was not safe.

Because the set of parts is too small and the structure is too complicated, if it is not done well, it will definitely not be able to hook the bullets in the magazine.

Now that's it, there's no need to worry about this problem.

Taichang then pointed to the magazine and explained: "Your magazine cannot be too big, it's enough to load ten bullets.

Because when the musket fires, the gun chamber will accumulate a lot of heat, and after firing ten shots, the gun chamber will probably be so hot that it will smoke.

If you continue to fire the gun, the chamber may deform, which will easily explode.

Moreover, after firing more than ten shots, the chamber may be burned red, and the lead will be lit as soon as it is hit by the chamber, which will make it easier to explode."

Dai Zi was stunned when he heard this.

It turns out that the more bullets there are in this magazine, the better.

He designed more than twenty bullets in the magazine at the beginning!

Because he had never participated in the battle, nor had he fired more than ten guns in a row, he didn't know that the chamber would smoke, nor did he know that the chamber would burn red.

He was stunned for a moment, and then he said sincerely: "The students have been taught."

Immediately afterwards, Taichang drew a pointed thing and explained: "I originally wanted to change the bullet structure. Since you designed all the semi-automatic rifles, then change them together with the bullet structure.

You see, we should make this warhead into a conical shape, so that the bullet can penetrate more and suffer less air resistance."

Air resistance?

Dai Zi asked carefully: "Your Majesty, please forgive the students for being stupid. What is air resistance?"

Taichang said in surprise: "Isn't this in your tutorial yet?"

Dai Zi shook his head without hesitation and said, "No."

OK, I don’t really know much about air resistance at this moment, and it will probably take a long time to form a science.

Taichang thought about it again, then asked: "You must have seen the Flying Dragon Battleship, right?"

Dai Zi nodded without hesitation and said, "Students have seen it. This time the students came here on the Flying Dragon Battleship."

Taichang nodded slightly, then asked again: "Where are hot air balloons, have you seen them?"

Dai Zi nodded without hesitation and said, "Your Majesty, there is a hot air balloon take-off and landing platform for Jinling Academy of Sciences. Students are lucky enough to sit in the hot air balloon to go to the sky."

very good.

Taichang then explained: "Since you have been on the Flying Dragon Battleship, you should know the external structure of the Flying Dragon Battleship.

The reason why the external structure of the Dragon Battleship is made into a sleek shape is to reduce the resistance to water.
