Marin watched melancholy as the young men and big girls in the fields bent over to harvest, and felt a little distressed. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 However, as soon as he turned his head, he saw Ada and his wife Lisa (Mona Lisa, please refer to the previous book for details) sitting on the edge of the field and painting leisurely, so he painted an oil painting of a farmer's harvest.

Marlin was amused - you old boy, but at ease. People work hard, and you don't invent a machine to help, don't you have a big brain? If you also invented the robot lion, why don't you invent a harvester......

"yes, I almost forgot Ada's mechanical talent!"

Then, as expected, Marin ran over and interrupted the idle painting between Leonardo da Vinci and Lisa and the flirtation between husband and wife:

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

"Don't do it! The old man has a business! Leonardo da Vinci curled his beard and was very dissatisfied with Marlin interrupting the sweetness of his husband and wife. It's also that Marin is usually easy-going, and if he is replaced by another nobleman, he doesn't dare to be so casual.

"Do it if you don't do it, or I'll let Karn carry you to do it!" Marin said without looking back.

"It's really ungraceful...... Da Vinci also said, how can he really not do it. After all, Marin was his food and clothing.

So, he was not ashamed, kissed Lisa on the edge of 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 Leonardo da Vinci rushed to Marin's temporary residence manor out of breath, Marin teased:

"Ada, why are you just gasping for a few steps? It won't be a kidney loss, right? I'm not talking about you, pay attention to moderation, you're not a young man like us, don't sing all night......"

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

Marin took out a quill and parchment and began to paint, letting Leonardo da Vinci sit down and drink some boiling water first.

However, Leonardo da Vinci did not sit there while drinking water, but stood curiously and watched Marlin draw......

When Marin painted a little half, Leonardo da Vinci became a little interested. Because, he could see, it was a machine. And machinery is one of the things that Leonardo da Vinci was interested in. Otherwise, in 1515, he would not have created the "Da Vinci Robot Lion" to give to the French king. Moreover, most of Leonardo da Vinci's mechanical achievements were made in his later years, mainly after the 16th century. Therefore, for the entire time period, Da Vinci has not yet entered the robot maniac stage. Because, presumably, he also focused on music, painting, and dissecting corpses.

But in this life, under the guidance of Marin, Leonardo da Vinci put a lot of energy into the mechanical side, researching 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 is interested. So, he quickly became interested in the diagram of the steam engine drawn by Marin......

……

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

Why? Because Catholicism ......

The steam engine differed from inventions like the musket in that it did not require a horse, and God knows what kind of panic it caused when it first appeared......

If it had been done early but aroused the disgust of the Holy See, Marin himself, and Leonardo da Vinci, I am afraid that it is very likely that they will be regarded as heretics by the Holy See......

If it is regarded as a heresy by the Holy See, although it will not be burned at the stake because of the status of the princes, the princes in the German region who see themselves unpleasantly will definitely use this as an excuse to line up to beat themselves, destroy themselves, and then divide their property...... Even the pious religious soldiers under his command may abandon themselves because of this......

Although, it is also possible to make a steam engine that will not be rejected by the Holy See, but Marin is not willing to take this risk. This was the beginning of the 16th century, not after Protestantism had defeated Catholicism.

Watt: Where did they get the steam engine? Protestant-controlled Britain. Only Protestantism would be more tolerant of the development of science. In the old Catholic Church, especially when the Pope was still more authoritative, it was a very risky thing to build a steam engine.

But now, Marin felt that the time was ripe......

Why? Because Marin's father-in-law will soon become pope......

When Archbishop Rovere became pope, who would dare to say that Marin was a heretic? In particular, say that my son-in-law is a heretic, come on, come on, do you want to be excommunicated?

Therefore, under the premise that his father-in-law would soon become pope, Marin finally let go of his courage and planned to let Leonardo da Vinci start developing the steam engine. Moreover, the development of the steam engine did not happen overnight. By the time Ada got the practical steam engine out, it is estimated that Archbishop Rovere would have become the pope. When the time comes, with the endorsement of the pope's father-in-law, Marin can confidently and boldly use the steam engine openly.

Of course, in order to reduce the difficulty, Marin did not sketch a two-cylinder steam engine as soon as he came up, but a single-cylinder one. After all, it has to be taken step by step, obviously Ada will do a good job of a single-cylinder, and then go to a double-cylinder.

Even, Marlin knew the principle of the lightweight Green steam engine. However, because the Green steam engine rotates by throwing the cylinder, the cylinder cannot be bigger, otherwise it will not be shaken. Therefore, the Green steam engine is only suitable for the power of small boats, not for the power of large ships.

Marin is engaged in steam engines, so he is naturally going to equip big ships, so he is destined to make a small Green steam engine, and Marlin does not plan to do it first. Moreover, the shaft in the middle of the Green steam engine has high requirements for materials. Because, he not only has to be firm, but he must be able to tie the cylinder and not let the cylinder get off. It also needs to be elastic enough to allow the cylinder to rotate without restricting its movement.

Of course, if the Green steam engine wants to be engaged, it can also be done. However, because the Green steam engine could not be bigger, it was 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 watta steam engine, a rudimentary steam engine was invented to pump water from mines.

If a steam engine had been built to drive a water pump, it would have been much easier for Marin to drain the water in the swamp. Unlike now, you can only smoke slowly with Dutch windmills.

Marin gave Leonardo da Vinci a drawing of the Watt steam engine. Although it is an 18th-century technique, it can be used even if it is taken out. The most important thing is that the pattern of the Watt steam engine is the most memorable to Marin...... Because, since Marin was in junior high school, I have seen such a picture, I have seen it in high school, and I have also seen dynamic pictures in college, so I am naturally the most impressed......

After drawing the pattern of the Watt steam engine to Leonardo da Vinci, Marin explained some important points, and then told Leonardo da Vinci to pay attention to secrecy to prevent being discovered by the Holy See and recognized as heretical......

For this, Leonardo da Vinci didn't need to say about Marindo, after all, he was also a scheming person. Back then, in the basement of his villa in Milan, he had obtained many corpses for autopsy, which was also contrary to the Holy See's ban. So, he was very bold, but also cautious, and knew to avoid people.

Considering that this matter should not be made public, Leonardo da Vinci was like Marin asking for a group of young craftsmen from serf origin as assistants, rather than those old craftsmen who had been hired from Italy. Because, serf craftsmen are not easy to leak. After all, they couldn't leave easily without Marin's permission. Unlike those seasoned craftsmen recruited from Italy, they are guest secretaries, more free, and easier to leak......
