The Rise of the European Emperor

Malin looked sadly at the young men and big girls in the field, bending over to harvest, and felt a little distressed. However, as soon as he turned his head, he saw Ada and his wife Lisa (Mona Lisa, you can refer to the previous book for details) sitting on the edge of the field and painting leisurely, and he painted oil paintings of farmers harvesting.

Marin was happy--you old boy, laid back. People work hard, you don't invent a machine to help, don't you have a big brain? Also invented the robot lion, why not invent a harvester...

"Yes, I almost forgot about Ada's mechanical talent!"

Then, Marin really ran over and interrupted the painting leisure between Da Vinci and Lisa and the flirting between husband and wife:

"Ada, come here, I'll find a job for you!"

"Don't do it! The old man has a business!" Da Vinci's beard curled up, and he was very dissatisfied with Marin's interruption of the sweetness of his husband and wife. It was also Marin who was usually easy-going, but when it was replaced by another nobleman, he didn't dare to be so casual.

"You have to do it, or I will let Kahn carry you to do it!" Marin said without looking back.

"It's really not graceful..." Da Vinci also said, how can he really quit. After all, Marin is his parents.

So he was not ashamed, kissed Lisa by the field, said goodbye to his wife, and sprinkled a handful of dog food on the young man who was harvesting wheat in the field...

When Da Vinci rushed to the manor where Marin temporarily lived, out of breath, Marin teased:

"Ada, why are you breathing so much after walking these few steps? You won't suffer from kidney failure, right? I didn't tell you, you have to pay attention to restraint, you are not a young man like us, don't sing every night..."

"Don't talk nonsense, the old man is very restrained, and God is the master..." Da Vinci blushed, obviously lying.

Marin took out a quill and parchment and began to paint, letting Da Vinci sit and drink some water first.

However, Da Vinci didn't sit there while drinking water, but stood on the side curiously watching Marin's drawing...

Da Vinci became a little interested when Marin had painted for a half-hour. Because, he saw, it was a machine. And machinery is one of the things that Da Vinci was interested in. Otherwise, in 1515, he would not have made the "Da Vinci Robotic Lion" and gave it to the King. Moreover, most of Da Vinci's mechanical achievements were made in his later years, mainly after the 16th century. Therefore, for the entire time period at present, Da Vinci has not yet entered the stage of robot madman. Because, he probably also focused on music, painting and dissection of cadavers and so on.

But in this life, under the guidance of Marin, Leonardo da Vinci put a lot of energy into mechanics, studied devices such as clockwork clocks and clockwork muskets, and also came up with a sextant. Of course, as long as it is science, Leonardo da Vinci was interested. So, he quickly became interested in Marin's drawing of a steam engine...

...

In fact, Marin had long planned to take the steam engine drawings to Leonardo da Vinci for study. However, the previous political environment did not allow...

Why? Because Catholic...

The steam engine is different from inventions like the musket because it doesn't require horses, and God knows what kind of panic it will cause when it first appears...

If it was done early, but it aroused the disgust of the Holy See, Marin himself, and Da Vinci, would probably be regarded as a heresy by the Holy See...

If it is regarded as a heresy by the Holy See, because of the status of princes, although they will not be tied to the stake and burned to death, those princes in Germany who are unhappy with themselves will definitely use this as an excuse to queue up to beat themselves and destroy themselves. and then divide up their property... Even the devout soldiers under my command may abandon themselves because of this...

Although, there is also the possibility that the steam engine will not be rejected by the Holy See, but Marin is not willing to take this risk. Because, this is the beginning of the 16th century, not the stage after Protestantism defeated Catholicism.

Where are the watts and their steam engines? Protestant-controlled England. Only Protestantism will be more tolerant of the development of science.

In the old-fashioned Catholic Church, especially when the Pope was still relatively authoritative, it was a very risky thing to engage in steam engines.

But now, Marin felt the time was right...

why? Because Marin's father-in-law is going to be Pope soon...

When Archbishop Rovere becomes Pope, who dares to call Marin a heretic? What's the matter, saying that my son-in-law is a heretic, come come, do you want to be excommunicated?

Therefore, on the premise that his father-in-law would soon become the Pope, Marin finally let go of his courage and planned to let Leonardo da Vinci start developing a steam engine. Moreover, the development of steam engines was not achieved overnight. By the time Ada came up with a practical steam engine, it is estimated that the Archbishop of Rovere has become the Pope. At that time, with the endorsement of the Pope's father-in-law, Marin can use the steam engine publicly with confidence.

Of course, in order to reduce the difficulty, Marin did not draw a sketch of a twin-cylinder steam engine, but a single-cylinder. After all, it is necessary to take it step by step. Obviously, Ada will make a single cylinder, and then go to a double cylinder.

Even Marin knew the principles of the lightweight Grimm steam engine. However, because the Green steam engine rotates by throwing the cylinder, it is impossible for the cylinder to be larger, otherwise it will not be able to be thrown. Therefore, the Green steam engine is only suitable for the power of small boats, not suitable for the power of large ships.

Marin's steam engine is naturally to be equipped for large ships, so it is destined to be a small Green steam engine, and Marin does not plan to do it first. Moreover, the shaft in the middle of the Green steam engine also has high material requirements. Because, he must not only be strong, but also be able to tie the cylinder so that the cylinder cannot be thrown off. Moreover, there must be enough elasticity to ensure that the cylinder can be rotated without restricting the movement of the cylinder.

Of course, if the Green steam engine wants to do it, it can be done. However, because the Green steam engine cannot be made larger, it is not very practical in industrial and agricultural production. It is better to build a large single-cylinder steam engine first. Even if it cannot be used to drive the ship for a while, it is good to use it to pump water. In fact, in the early 18th century, before Watt invented the Vata steam engine, someone invented the humble steam engine to pump water in the mines.

It would be much easier for Marin to drain the swamp if he had a steam engine to drive the water pump. Unlike now, it can only be smoked slowly with a Dutch windmill.

Marin gave Leonardo a drawing of a Watt steam engine. Although it is a technology from the 18th century, it can be used when it is taken out. The most important thing is that Marin has the deepest memory of the drawing of the Watt steam engine... Because Marin has seen such a picture since junior high school, he has seen it in high school, and he has seen dynamic pictures in college, so he is naturally the most impressed. ...

After drawing the diagram of the Watt steam engine to Da Vinci, Marin explained some key points, and then told Da Vinci to keep it secret to prevent it from being discovered by the Holy See and identified as a heresy...

For this, Da Vinci does not need to say Malindo, after all, he is also a man of scheming. Back then, in the basement of his villa in Milan, he had brought many corpses for autopsy, which also violated the Holy See's prohibition. Therefore, he is very bold, but also very cautious, knowing to avoid others.

Considering that this matter should not be made public, Leonardo da Vinci, like Marin, asked a group of young artisans from serfs to serve as assistants, rather than those old artisans invited from Italy. Because, serf artisans are not easy to leak. After all, they couldn't leave easily without Marin's permission. Unlike those experienced craftsmen recruited by Italy, who are guest ministers, they are more free, and it is easier to leak secrets...
