The Rise of the European Emperor

Marin was very depressed when he thought that the four particularly large territories of the Kingdom of Bohemia, the Kingdom of Hungary, the Principality of Silesia and the Principality of Moravia were about to miss him.

In the evening, Marin tossed Angela hard and asked for it a few times. Angela pestered Marin breathlessly after finishing the incident, and asked suspiciously:

"Dear, why are you so excited today? I almost tossed people to death..."

Marin didn't hide it from him and spoke his mind. Angela's eyes lit up when she heard it. You know, those are four countries with a large area. Moreover, the Kingdom of Bohemia is also the head of the four secular electors of the Holy Roman Empire.

So, Angela said with bright eyes:

"How about we let Caesar marry Anne of Bohemia? That's the king of Bohemia! After becoming an elector!"

Marin shook his head, not to mention that the Kingdom of Hungary is a powder keg region. Just not relying on the sea, not suitable for the development of large-scale navigation, is far worse than the United Kingdom.

Moreover, his territory and the United Kingdom are only separated by the North Sea, and they are not far away. If you get the Kingdom of Bohemia, Hungary, Silesia and Moravia, not to mention the problem of wars over there, it is too far from East Frisian, separated by thousands of mountains and rivers, and difficult to manage. a big question.

However, regarding the British plan, Marin did not tell Angela to avoid Angela being lax and accidentally saying it out.

Then, Angela felt that it would be good for her second son to be the king and elector of Bohemia. So, she took the initiative to pounce and entangled Marin...

Marin said with tears in his eyes:

"It's impossible for a woman to get pregnant. Because your mouth is facing down, the liquid drains directly."

"Then you go up and down, I want to have another son and become the king and elector of Bohemia!" Angela said stubbornly.

Marin was speechless, but he was still very embarrassed...

The next morning, Marin felt very sore in his waist, and his body was depleted. While rubbing his waist, he muttered:

"It's no wonder that the emperors of Huaxia died early. Kang Mazi has been emperor for 61 years, and he has been in power for a long time. Moreover, that's why he ascended the throne at the age of 8..."

"Huh... That's not right, his grandson Qianlong is also very rambunctious. Not only are there a bunch of them in the palace, but there is also a mammoth Rong (Xia Yuhe) by the Daming Lake outside... Why does he live to be 89 years old? Could it be? , he has an ancestral secret recipe? Well, I still have to send someone to Daming to find such an ancestral secret recipe..."

Anyway, Marin found that after he crossed, except for the better memory of his brain, his body hadn't been strengthened. You can't fight ten one at a time, and you can't count women in one night...

In short, he is still a normal body. It's just that after long-term training in martial arts, the body is stronger than the average person. As a normal man, if there are many times at night, it is inevitable that you will have back pain and vain steps...

Rubbing his waist and stepping on a "spacewalk" (not MJ's dance spacewalk, it's Armstrong's lithe spacewalk, which looks like a staggering, authentic spacewalk...), Marin came to the palace The hospital's office, began to process urgent documents...

Soon, Jeffrey suddenly came to Marin's office and invited him to the road completion ceremony...

"The road completion ceremony? You want me to attend such a trivial matter?" Marin was surprised.

Jeffrey was actually a little surprised, so he asked back:

"Lord Duke, didn't you make me pay special attention to the construction of the volcanic ash (cement) road?"

"Volcanic ash?" Marin was stunned for a moment, then suddenly reacted:

"It turned out to be a cement road...Okay, I'll go right away, go and prepare the carriage and guards!"

Soon, the four-wheel spring shock-absorbing carriage was ready, and Marin and Geoffrey rode into the carriage of the carriage, which was covered with tinplate and had a high degree of protection. Around the carriage, there were fierce guards wearing chest plate armor.

Under the escort of a large number of guards,

Marin's carriage soon arrived at the edge of the cement road outside the north gate...

After getting off the car, what Marin saw was a neat and flat rural cement road, similar to the cement road in Marin's hometown in later generations.

This is a standard country concrete road with a width of 3.5 meters and a thickness of 20 cm. Also, on the concrete pavement, Marin had people cut a knife every few meters, supposedly to prevent the pavement from swelling or shrinking.

In fact, the fly ash cement used in Marin paving cement road is a kind of cement with lower expansion coefficient and better crack resistance. Fortunately, Marin set up a cooking salt base, otherwise, there would not be so much supply of fly ash. In later generations, ordinary cement roads use the simplest Portland cement. Only in reservoirs, coastal defense, river defense and other projects, cement with good waterproof and anti-corrosion properties such as fly ash cement will be used.

The road is paved with fly ash cement, and it is a rural cement road that is only 3.5 meters wide, and it is also possible not to cut a knife. Of course, it's better after cutting the knife.

In addition, cement pavement is not smooth. Otherwise, on a rainy day, people can "skate" on the concrete road. On the cement road, many shallow bars were played by the construction workers with thin lines. Although the depth is very shallow, the friction coefficient of the cement road has been improved a lot, but the friction is not high compared to the dirt road. The most important thing is that with this very shallow "bar", even if it rains, the concrete road will not be slippery.

In fact, the cement road was repaired more than a month ago. It's just that the cement pavement needs to be air-dried. So, after waiting for more than a month, when the cement road was completely dry, I invited Geoffrey to check it out.

Jeffrey remembered that Marin had said that the road was so important that he wanted to follow it himself. Obviously, this road is very important to Marin, so he invited Marin to attend the road completion ceremony. Well, this ceremony was also "invented" by Marin...

The so-called road completion ceremony is actually to let Marin unveil the plaque, and then personally ride the carriage back and forth on the road.

Marin happily let his carriage ride on this small cement road that is only more than 3 kilometers long...

After getting on the concrete road, the carriage quickly accelerated. On such a flat concrete road, the carriage ran fast. Later, when the car got up to speed, it basically didn't need the horse to use too much force, and galloped on the road directly by inertia. Even the horse wanted to stop, but was pushed forward by the carriage behind...

If the horse pulling the cart could speak at this time, the horse would definitely say:

"Niang Xipi, I can't stop at all!"

The horse ran desperately. If it slowed down, the carriage behind it still pushed the horse forward. It seemed that the horse was not allowed to slow down. This made the horse very depressed, so it kept running. Fortunately, under inertia, the horses did not pull the cart too hard at this time. Unlike those mountain roads with high resistance, the car can't move if the horse is pulled.

Soon, the more than three kilometers of cement road came to an end. However, at this time, the speed of the horse and the carriage had reached a very high value. The horse wanted to stop, but was held back by the carriage and continued to move forward...

Fortunately, European carriages have brakes. The driver saw that the road was coming to an end and hurriedly braked. The brake is on the left, a simple lever principle - a long arm in front, all the way to the left-hand side of the driver's side. At the back is a short arm, with a high friction thing attached to the top. There's no rubber right now, that friction material, it's made of leather.

The driver raised his long arm with his left hand, and the leather friction pad leaned on the wheel and rubbed against the wheel, trying to use the friction to stop the wheel. However, unlike the brake pads of later generations, which are on the inside of the rim, the brake pads at this time are actually on the outside of the wheel, and the friction is also on the outside of the wheel...

At the same time, the driver's right hand also began to pull the reins, and the horse also stopped...

It's a pity that the carriage ran too fast this time. Not only was the horse difficult to stop for a while due to inertia, but there was also a very harsh braking sound from the wheel - no way, who called the carriage too fast ...

Fortunately, there are no lakes and cliffs ahead. Some distance after the year on the dirt road, the carriage really came to a stop. The driver was so frightened that he pleaded with Marin again and again. After all, this was a serious mistake.

Marin didn't blame the driver, because he knew that people of this age underestimated the convenience of concrete roads. So, there is nothing wrong with making a mistake. Also, he didn't have a problem himself.

At this time, Marin's attention was completely attracted by this rural concrete road that was hundreds of years ahead of the times. Just now, he clearly felt that the carriage was thrown at the highest speed in history. Although it still can't catch up with the cars of later generations, it will definitely catch up with the battery car. In a previous life, Marin was able to pull up to a speed of 26 yards when he rode that second-hand battery bike. This time the carriage was on the cement road, and it almost ran out of the speed of an electric bicycle.

In this day and age, even on the relatively flat Roman avenues, the speed of carriages rarely exceeded 20 kilometers per hour. That's because there are uneven areas between the stones on Roman Avenue, which increases friction and causes small vibrations in the carriage. Therefore, the speed of the carriage generally does not exceed 20 kilometers per hour. Of course, if you encounter a Ferrari-level pull horse and run hard, you can break through this speed, but it's rare.

But on the concrete road in the countryside, even an ordinary carriage can easily run at a speed of more than 20 kilometers per hour. The only problem is the brakes.

Marin intends to let people study the simple foot braking system in later generations, lest the coachman brake with his left hand and pull the reins with his right hand, and both sides can't do well...

Moreover, Marin found that after running down the 3-kilometer road, the horse pulling the cart was not tired at all, and he looked very energetic.

It is no wonder that on the cement road, when the speed of the carriage is raised, the inertia of the carriage and the small friction coefficient of the road surface make the force required for the horse to pull the carriage much smaller. Conversely, when the horse wants to slow down, it is often pushed forward by the inertia of the carriage. Therefore, horses pull carts and walk on concrete roads, which saves a lot of effort than on dirt roads and cross roads. In this way, the distance that the carriage continues to travel is much longer than on other roads. In this way, the average daily distance traveled by the carriage will also increase by a large margin. Even, reaching twice is not a myth.

An ordinary carriage can run 100 kilometers a day on ordinary roads, which is amazing. Because, after running for an hour, the carriage must stop to rest. Not for people to rest, but for horses to rest. Otherwise, the horses will be exhausted. In ancient Roman times, on Roman Avenue, the stagecoach could only run 160 kilometers in 24 hours, and it was necessary to rest and change horses in the middle. Otherwise, the horses can't take it.

On the concrete road, the horse pulling the cart has less effort, and the rest period is longer, so it can naturally run farther. If the horse is better physically, it is not a myth to drag a horse-drawn carriage on a concrete road for 200 kilometers a day... If it is a double horse-drawn carriage, the speed should be faster. Of course, this is a manned vehicle, and it is not difficult to pull up a horse. If it is a truck with a heavy load, the speed will be much slower... After all, the pulling force of the horse is far behind that of the machine... The average car has more than 100 horsepower, and it can stand up to hundreds of horses...
