Seeing Da Vinci nodding, Marin was overjoyed, and quickly took out the contract he had prepared a long time ago, ready to sign it on the spot.
After Da Vinci got the contract, he was taken aback. Because, Marin wrote 30 years in the contract period...
Thirty years, Da Vinci can't guarantee whether he can live to thirty years. In fact, this 30-year period is basically equivalent to the rest of Da Vinci's life, and he will work for Marin.
Therefore, Da Vinci hesitated... Even Da Vinci doubted whether Marin himself could persist for 30 years. Because Marin is a military officer, and he will fight for the emperor in the future. If Marin accidentally burps on the battlefield, how will Da Vinci arrange it
In this regard, Marin expressed generously that he was willing to add corresponding clauses to the contract, stipulating that if Marin died in battle, Da Vinci could leave freely. Of course, you can also stay and fulfill the contract, and the treatment can only increase, not decrease...
After all the words were said, Da Vinci no longer hesitated. He signed his own name on the contract, and Marin immediately signed his own name...
So far, Da Vinci has officially become a long-term mental worker under Marin, with a service period of 30 years...
Marin didn't let Da Vinci work immediately, but let Da Vinci relax for a few days. Then, the fat girl who looked like Teacher Da Vinci was left behind to have fun with Da Vinci...
A few days later, Da Vinci was almost relaxed, so he came to Marin's castle and started talking about work...
"Oh, Ada, have you had enough rest?"
"Enough is enough..." Da Vinci seemed to be blushing. These days, he finally lived like a normal man. Under the harmony of yin and yang, it is refreshing.
"Is that girl satisfied with her service?"
"Satisfaction is satisfaction, but you know, she's just a prostitute, I can't marry her." This is true, marrying a prostitute requires a very thick skin, and people who are not afraid of ridicule can do it .
The West is no better than the East, and Easterners can marry several. Of course, the Easterners did bring prostitutes home, but only as concubines, and no one wanted their first wife to be a prostitute.
For example, in the famous "Du Shiniang Sinks the Treasure Box in Anger", Li Jia was overwhelmed by love and wanted to marry Du Shiniang as his wife. But in the end, thinking about it, it was extremely difficult. Because, as a son of an official family, if he really wants to marry Du Shiniang, according to the ancient and harsh patriarchal system, Li Jia may be directly executed with a stick. The best result is nothing more than accepting her as a concubine. Therefore, under the temptation of Sun Fu, Li Jia agreed to sell Du Shiniang. It's not that Li Jia is ruthless, but that he really can't bear the pressure. If you want to marry a prostitute as your wife, you must be prepared to be beaten to death by the family law...
The same is true in the West. Moreover, the West is only allowed to marry one wife, and there is no such thing as taking a concubine. Therefore, when there is only one choice, no one wants to marry a woman who is a prostitute. Unless, this person really can't find a wife, and he can't care about being shameless...
Da Vinci was a smart guy, always has been. He quietly wrote down Da Vinci's manuscript, and also used the mirror image text that was convenient for secrecy, because he was afraid that the Holy See would find out that he was engaged in anatomy and natural science and would contradict the Holy See.
Therefore, such a smart person is unlikely to marry a prostitute as soon as his brain is hot. What's more, Da Vinci regarded this fat prostitute as the shadow of Sister Hynia.
"That's right. After a while, I'll send someone to Italy to help you find a well-bred lady... By the way, what are your requirements? For example, appearance, do you like fat or thin? Tall or short?"
"It's not urgent. I'll tell you after I think about it. My boss, tell me, what should I do now? I think, if you spend so much money and kidnap me yourself, you won't keep me in vain." Bar?"
"Of course, I invite you here because I hope you will help me with great things!"
"I like this saying, I Da Vinci, I was born to like to do great things!"
"Ada, have you heard of clockwork?"
"Clockwork? Of course, many famous craftsmen are now seeking to use clockwork to make clocks. I have seen it many times in Italy, and I am very familiar with some clockwork craftsmen..."
"You know how to make clockwork yourself?"
"No, but I've worked with craftsmen who can wind up clockwork, and I've bought clockwork..."
"Then do you know where there is a master who makes clockwork?"
"There are a few in Milan, and there are also Florence..."
"Great, write me a list, I'll send someone to recruit..."
"What are you going to do?"
"Two purposes, one is to make more accurate clocks..." More precisely, Marin is to make marine clocks.
The current clocks and watches have too much error, and it is difficult to calculate the longitude and determine the coordinates when used for large voyages. Therefore, Marin needs a more accurate nautical clock, that is, a more accurate clock.
"Although I am also involved in clocks and watches, I am not the top watch craftsman because I don't concentrate on studying this. However, I know a watch master. His name is Miller, and he is a famous watch master in Milan..."
"Famous watch master? Can I please move?"
"You can knock out the brought..."
"Well, that makes sense..."
"What's the other use?"
"A trigger for a musket?"
"What? Use a clockwork to fire a musket? It's a bold idea. What's the specific principle?" Da Vinci was an inventor in the first place, and he was very interested in new inventions.
"It is to use the clockwork to accumulate energy first, and then use the trigger to loosen the tightened clockwork, so that the steel wheel driven by the clockwork will rub against the flint and ignite the gunpowder..."
"What a genius idea..." Da Vinci was a military contractor and knew weapons. He thought about it, and found that the idea was really good, so he admired it aloud.
"Hehe, it's a pity that I don't know how to make crafts. I heard that you are good at this, so I invited you to develop this..."
"I can't do it alone, because I'm not good at making clockwork. So, I need a few craftsmen who are proficient in making clockwork to help me make clockwork..."
"That's no problem. I'll send someone to Italy to recruit right away. However, those craftsmen can help you make the clockwork, but don't let those hired craftsmen participate in the development and manufacture of the spring-fired revolver..."
"You want to keep the secret?"
"Yes, I have a revolver that doesn't require a matchlock. I can equip my cavalry with this. In this way, my cavalry not only has impact power, but also has long-range attack power."
"With all due respect, it is very difficult for cavalry to aim while riding on horseback. Moreover, cavalry is unlikely to use long-barreled muskets, only short guns. Such muskets have a relatively short range..."
"You are right. Although the effective range of cavalry with short guns may be within 30 yards, that is not the most important thing. I can equip light cavalry with such muskets to use against plate armor knights. My light cavalry, can At a certain distance, hit the plate knight with the musket, and the plate knight is unlikely to catch up with my light cavalry, and it is impossible to escape... "
"However, the musket can only be fired once, and it is very troublesome to finish reloading..."
"Of course I know, but I can let my cavalry carry five or six revolvers..."
"That's okay? However, the manufacturing cost of a revolver with a clockwork is very high? You know, such a precision device is very labor-intensive and requires high-quality materials. Therefore, the price of a revolver is It will probably be more expensive.”
"I know, but I don't plan to equip many such cavalry. Moreover, this kind of cavalry is specially used to deal with the opponent's plate armor knights. You don't need too many people, just need to be large..."
"What you said is very reasonable. Such an army is indeed the nemesis of the plate armor knights who run slowly..."
"Of course, I'm a war genius..." Marin didn't want Bilian to put gold on his face...
In fact, this branch of arms was indeed rampant in the 16th century. His title is called "Knight in Black Shirt", which is an important arm of Germany. The black-shirted knights under the command of Charles V once defeated the French plate armored knights by relying on their revolvers and muskets.
However, this is only suitable for attacking the plate armor knights popular in this era, and the spear infantry phalanx without long-range firepower. When the Europeans abandoned the bulky plate armor knights, the black shirt knights were easily bitten and chased by the opponent's light cavalry. After the 17th century, most infantry used long-barreled muskets. The short guns used by the black-shirted knights can't compare with the long-barreled infantry models at all, and they can only court death when they shoot at each other. Therefore, the black shirt knight began in the late 16th century and gradually disappeared. However, the sister unit of the black-shirted knight, the dragoon, has become very popular and has become an important mobile firepower unit...
In this way, Leonardo Da Vinci took over two engineering projects in one breath-a clock using a clockwork, and a revolver using a clockwork. Among them, the watch that uses a clockwork, Marin, can be slowed down, but the revolver gun that uses a clockwork needs to be developed as soon as possible, and it must be kept secret...
Moreover, the difficulty of firing a musket with a wheel is much smaller than that of a clockwork. After all, clockwork clocks require high precision. As for the rotary gun, it only needs to be able to rub sparks and ignite the gunpowder. Therefore, the difficulty of the two is not at the same level.
The only disadvantage is that the cost of the musket is very high due to the use of a complex spring. But this is also the technical barrier that Marin set up for the poor nobles - not that you can't make it, but that you can't afford it because the cost is too high...
To be honest, Marin can completely let Da Vinci engage in flintlock guns. Moreover, the cost of flintlock guns is much lower, which is convenient for large-scale installation. However, flintlock guns are easy to imitate. If Marin's opponents were equipped with flintlock guns on a large scale, then Marin would dig a hole and bury himself. Therefore, Marin, who is not short of money, decided to develop a revolver that only local tyrants can afford to equip, so that those poor monarchs can't afford to equip it even if they have learned the technology.
You know, the black-shirted knights in Marin's preparation plan each carry several revolvers. If you don't have strong financial resources, the general lord can't afford to equip...
