The Rise of the European Emperor

When he made the hydrogen balloon himself, Marin found out that making a hydrogen balloon is also a high-tech...

There is no problem in this step of hydrogen production. Marin has zinc metal in hand, and dilute sulfuric acid can be diluted by scooping some concentrated sulfuric acid from the tank and adding water. But the collection of hydrogen seems to be a bit difficult. The main thing is to ensure that the hydrogen does not leak.

At first, Marin used wide-mouth bottles and found it difficult to keep the hydrogen from leaking. Later, he made it directly with a narrow-mouth bottle, and directly put a balloon over the bottle mouth to collect hydrogen.

But something went wrong with the balloon. Marin didn't have high-elasticity rubber in his hands, so he had to sew a simple balloon out of cowhide. However, the airtightness of this sewn balloon is not good, and there is a slight air leakage. Although gluing can solve the problem, the problem is that the quality of glue these days is very poor, but it does not have the ability of 502 glue in later generations. Marin can guarantee that the glue-bonded balloons of this era are fine if they are small, but they will definitely collapse when they get bigger. So, don't think about large manned hydrogen balloons or something.

In the end, Marin found a suitable hydrogen balloon raw material from the slaughterhouse-pig urine foam...

But what makes Marin depressed is that domestic pigs in Europe are smaller in this era, and their urine bubbles are also smaller. Looking at the pig urine bubbles that were obviously one size smaller than the pig urine bubbles he had seen in his previous life, Marin was a little speechless.

But in any case, the airtightness of pig urine bubbles is indeed much better than that of sewn leather balls, and it can also expand a little bit. Then, in the backyard of the Aurich Palace, I saw the bear child Caesar, with little Robert, who could not walk unsteadily, dragging a few pig urine and hydrogen balloons all over the yard...

Later, deeply inspired, Marin went to the slaughterhouse, made a cow urine bubble, and made a large hydrogen balloon. But I didn't expect that the buoyancy of this large hydrogen balloon was too strong. When young Robert took this large hydrogen balloon alone, he was almost taken away. If it wasn't for Marin's quick-witted eyes, the future Pope Robert might have risen to the sky with a balloon of cow urine... Then he would fall into a meat pie...

Then, Ferris, a pregnant woman with a big belly, exploded—she chased after Marin, trying to bite and scratch...

You know, Ferris regards Robert as the future Pope. After all, the temptation of "the Pope's mother" is too great for a woman. Marin was so messed up that she almost shattered her dream. In addition, the mother's love for the cub and the pregnant woman's emotions were inherently unstable, so she broke out.

If it were another woman who dared to do this, Marin would have suppressed it long ago. However, Felice was the Pope's daughter, her background was too big, and she was pregnant with his child, so Marin had to admit her wrongdoing, and finally calmed Felice's unstable emotions. It was also fortunate that he had practiced martial arts and hid quickly, otherwise he would have been scratched with a blood mark on his face.

Having learned his lesson, Marin quickly took away the large hydrogen balloon made of cow urine, leaving only the two sons and a few piglets to play with the hydrogen balloon.

...

Unexpectedly, this incident shocked Da Vinci.

After hearing about the hydrogen balloon that almost brought Robert Jr. to the sky, the greatest scientist of this era suddenly had a dream of flying:

"Grand Duke, you can make me more cow urine balloons, I want to tie them together and take me to the sky to see..."

Marin almost jumped up:

"Ada, why do you want to die so hard?"

"Death?" Da Vinci didn't understand.

Marin quickly made a wave of popular science:

"The hydrogen balloon itself contains flammable and explosive gas, and after the hydrogen balloon reaches high altitude, because the high air pressure is very low, the pressure inside the balloon is much greater than the external environment, and then it bursts and explodes by itself... Barabara... In short, go on The queen is dead!" Marin explained for a long time, his mouth was dry.

Da Vinci blinked his eyes and said:

"What is air pressure? How do you know high air pressure becomes low?"

Marin is about to cry - I'm a liberal arts student! Although the basic physical chemistry in middle school was okay, it was not a major...

Then, he had to take out the ultimate shield:

"This is what my teacher Einstein said..."

Da Vinci was even more confused...

In order to demonstrate the danger of hydrogen balloons, Marin detonated two cow urine hydrogen balloons in front of Da Vinci, and instantly burned a sheep as a test object...

However, Da Vinci was frightened, as were Angela and Ferris. After confiscating the children's pig urine bubbles with hydrogen balloons, Marin was also chased and killed by the two women for a while:

"Dare to give children such a dangerous thing to play with, do you want to kill them?" Even Angela, who was very gentle, was furious this time...

Marin wanted to cry without tears, so he had to sleep in the office alone at night...

Speaking of which, Marin was careless. Although the pig urine bubble hydrogen balloon is small, it is also filled with hydrogen gas. The two little guys are the age of bear children. If they accidentally touch an open flame, they may really be burned. Therefore, facing Angela and Ferris' questioning this time, he could only admit his mistake. If Da Vinci didn't want to play Feitian, Marin almost forgot the danger of hydrogen balloons.

...

Although the old boy Da Vinci gave up the unreliable plan of tying Feitian with a hydrogen balloon with cow urine because of the high risk, he still developed a strong interest in hydrogen and applied for more concentrated sulfuric acid to do experiments.

Marin took a look - is this worth it? Da Vinci was the only reliable scientist under Marin's command. If he was accidentally killed or burned while playing with hydrogen, his loss would be too great.

So Marin had to use something else to divert Da Vinci's attention:

"Ada, can you help me redesign a steering wheel system? The current steering wheel is a bit backward, and it can't be steered by one person..."

What Marin said was right. The steering wheel system, which was designed by a group of watchmakers before, used a lot of copper gears and copper rods as levers. Although it can be used, it only saves half of the force compared to the early rudder stock. That is to say, it used to be 4 sailors to turn the rudder when turning, but now only 2 sailors need to turn the steering wheel together...

That wasn't enough, though, and Marin felt that the later version with moving pulleys and ropes was better. However, there is a problem, that is, the ropes used for sailing in later generations are basically made of sisal fiber, which are wear-resistant and seawater-resistant special sailing ropes. But now Marin has only flax ropes, and the quality is obviously not up to standard. Therefore, Marin originally planned to let Da Vinci develop a new steering wheel system after the Mexican sisal was found. Anyway, it's useless to get it out now.

But seeing that Da Vinci was obsessed with dangerous hydrogen, Marin had no choice but to develop a steering wheel system that controlled the steering plate with a moving pulley rope. Anyway, get it out first, and then change the rope when you have sisal.

"It's time for Ada to stop now?" Malin breathed a sigh of relief.

When the new steering wheel system is developed, it is estimated that it will be a long time. Maybe Da Vinci has long forgotten about hydrogen...

But things backfired. A few days later, Da Vinci came to Marin with a stack of blueprints on his face:

"Grand Duke, I have researched..."

Marin:  …

"So fast?" Marin was a little surprised. He remembered that he spent a long time looking for the group of watchmakers to study the steering wheel system of the gear lever series.

But unexpectedly, Da Vinci raised his head suspiciously and asked:

"Does it take a long time? You have all come up with ideas. I will turn it into a real thing, won't it take a few days?"

Marlin's heart was instantly damaged by 100,000 critical hits...

"It seems that we don't understand the world of genius..." Marin sighed.

It was also because I thought it was wrong. The watchmakers in the past were only craftsmen at best. Who is Da Vinci? They are the top scientists of this era. At the same time, people's hands-on ability is also super strong, otherwise they would not be able to create a robot lion - although that was around 1516... If you use one identity to quantify Da Vinci's ability, then the academician of the Academy of Sciences and the academician of the Academy of Engineering, is The best description of Da Vinci's abilities...

Therefore, you can't look at geniuses in the eyes of ordinary people, they are not from the same plane as you...
