Marin was very depressed when he thought that four particularly large territories, namely the Kingdom of Bohemia, the Kingdom of Hungary, the Principal of Silesia and the Principal of Moravia, were about to miss their own family.
In the evening, Marin tossed Angela hard and asked for it several times. Angela panted and asked in confusion:
"Dear, why are you so excited today? You almost tormented to death..."
Marin did not hide it from him and said his thoughts. When Angela heard it, her eyes shone a little. You know, those were four large countries. Moreover, the Bohemia Kingdom was also the leader of the four secular elected emperors of the Holy Roman Empire.
Then Angela said with all her eyes:
"Or why should we let Caesar marry Anne of Bohemia? That's the king of Bohemia! After becoming the king, he will be a prince!"
Marin shook his head, not to mention that the Kingdom of Hungary is a powder keg area. It is far worse than that of Britain if it does not rely on the sea and is not suitable for the development of large-scale navigation.
Moreover, my territory is only separated from Britain from the North Sea and is not far away. If I get the Kingdom of Bohemia, the Kingdom of Hungary, Silesia and Moravia, not to mention the problem of wars over there, it is even too far from East Friesland and is far away from thousands of mountains and rivers, and it is difficult to manage, it is also a big problem.
However, regarding the UK's plan, Marin did not tell Angela to avoid Angela's sluggish words and accidentally telling her.
Then, Angela felt that it seemed good to let her second son be a Bohemian king and electorate. So she took the initiative to pounce on Marin and tangled...
Marin was speechless, but still put his face on him...
The next morning, Marin felt aching and her body was extremely deficient. He rubbed his waist while muttering:
"No wonder the emperors of China died long ago. Kang Mazi has been the emperor for 61 years, and they have been in power for a long time. Moreover, it was because he ascended the throne at the age of 8..."
"Huh... it's not right. Not only did his grandson Qianlong have a bunch of people in the palace, but there were also Mama Rong (Xia Yuhe) on the banks of Daming Lake outside... Why could he live to be 89 years old? Could it be that he has a secret recipe for ancestral inheritance? Well, he still has to send someone to the Ming Dynasty to find such a secret recipe for ancestral inheritance..."
Anyway, Marin discovered that after traveling through time, his body did not improve except for his better brain memory.
In short, he is still in a normal body. However, after long-term exercise of martial arts, his body is stronger than that of ordinary people.
Rubbing his waist and stepping on the "Space Step" (not the dance space step of MJ, but the light space step of Armstrong, which looks like a staggering footstep, authentic space step...), Marin came to the office in the front yard of the palace and began to process the critical documents...
Soon, Jeffrey suddenly came to Marin's office and invited him to attend the road completion ceremony...
"The road completion ceremony? I have to attend such a small matter?" Marin was surprised.
Jeffrey was actually a little surprised, so he asked:
"Duke, didn't you let me pay special attention to the construction of the volcanic ash (cement) road?"
"Volcanic ash?" Marin was stunned for a moment, then suddenly reacted:
"So it's a cement road... OK, I'll go right away, you go and prepare the carriage and guard!"
Soon, the four-wheeled spring shock-absorbing carriage was ready. Marin and Jeffrey took the carriage outside the carriage, which was booked with a high protective force. The carriage was surrounded by fierce guards wearing chest armor.
Under the escort of a large number of guards, Malin's carriage quickly arrived at the edge of the cement road outside the north gate...
After getting off the bus, what Malin saw was a neat and flat rural cement road, which was similar to the cement road in Marlin's hometown in later generations.
This is a standard rural cement road with a width of 3.5 meters and a thickness of 20 cm. Moreover, on the cement pavement, Marin asked people to cut every few meters, which is said to prevent the pavement from expanding or shrinking.
In fact, the fly ash cement used in Malin paving cement roads is a cement variety with low expansion coefficient and good crack resistance. Thanks to Malin, it was because of the fact that he built a salt boiling base, otherwise, there would not be so much fly ash supply. In later generations, ordinary cement roads used the simplest silicate cement. Only reservoirs, coastal defense, river defense and other projects would use cement with good waterproof and corrosion resistance such as fly ash cement.
It is possible to pave the road with fly ash cement, and it is only 3.5 meters wide to pave rural cement roads, so it is OK to not cut the knife. Of course, it is better after cutting the knife.
In addition, the cement pavement is not smooth. Otherwise, on a rainy day, people can "skate" on the cement pavement. On the cement pavement, the construction staff used thin lines to bounce many shallow poles. Although the depth is very shallow, the friction coefficient of the cement pavement has increased a lot, but the friction is not high compared to the dirt road. The most important thing is that with these very shallow poles, even if it rains, the cement pavement will not slip.
In fact, this cement road was repaired more than a month ago. However, the cement road surface needed to be air-dried. So after waiting for more than a month, Jeffrey was invited to inspect the cement road surface after being completely dry and hard.
Jeffrey remembered that Marin had said that this road was very important and he wanted to follow up in person. Obviously, this road was very important to Marin, so he invited Marin to attend the road completion ceremony. Well, this kind of ceremony was also "invented" by Marin...
The so-called road completion ceremony is actually to let Marin unveil the plaque and then ride the carriage back and forth on the road.
Marin happily let his carriage on this small cement road that is only more than 3 kilometers long...
After getting on the cement road, the carriage quickly accelerated. On such a flat cement road, the carriage ran rapidly. Later, when the carriage started to speed, it basically didn't take too much effort to run on the road, and it was directly driven forward by the inertia. Even the horse wanted to stop, but was pushed forward by the carriage behind...
This chapter is not finished yet, please click on the next page to continue reading the exciting content later! If the horse pulling the cart can speak at this time, the horse will definitely say:
"My mom, I can't stop at all!"
The horse ran desperately. If it slowed down, the carriage behind it was still pushing the horse forward, as if it would not slow down. This made the horse very depressed, so it kept running. Fortunately, under inertia, the horse did not pull the cart too hard at this time. Unlike those mountain roads with great resistance, if the horse did not pull, the cart could not move.
Soon, the more than three kilometers of cement road ended. However, at this time, the speed of the horse and the carriage 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. When the coachman saw that the road was over, he quickly braked manually. The brake was on the left, and a simple lever principle - the front is a long arm, which extends all the way to the left hand side of the coachman. The back is a short arm, and the top is connected with something with a lot of friction. There is no rubber at the moment, and the friction is made of leather.
The coachman raised his long arm with his left hand up. The leather friction pad leaned on the wheel and rubbed against the wheel, trying to stop the wheel by relying on the friction. However, unlike the brake pads in later generations on the inside of the ring, 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 coachman's right hand also began to pull the reins and control the horse to stop...
Unfortunately, the carriage ran too fast this time. Not only did the horses find it difficult to stop for a moment because of inertia, but there was also a very harsh sound of brakes on the wheels - there was no way, who said the carriage was too fast...
Fortunately, there were no lakes or cliffs in front. After a distance after getting on the dirt road, the carriage actually stopped. The coachman was so scared that he apologized to Marin repeatedly. After all, this was a serious mistake.
Marin did not blame the coachman because he knew that people of this era probably did not have enough convenience for cement roads. Therefore, it was nothing wrong to make any mistakes. Moreover, he also had no problems.
At this time, Marin's attention was completely attracted by this rural cement road that was leading the era for hundreds of years. Just now, he clearly felt that the carriage had thrown the highest speed ever. Although it could not catch up with the cars of later generations, it would definitely be able to catch up with the electric car. In the past life, Marin rode the second-hand electric car and could reach a speed of 26 yards. This time, the carriage almost ran the speed of the electric bicycle on the cement road.
In this era, even on the relatively flat Roman Avenue, the speed of the carriage rarely exceeds 20 kilometers per hour. That is because there are uneven areas between the stones on the Roman Avenue, which increase friction and causes a small vibration of the carriage. Therefore, the speed of the carriage generally does not exceed 20 kilometers per hour. Of course, if you encounter a Ferrari-level horse-drawn horse and run hard, you can break through this speed, but it is rare.
But on rural cement roads, even ordinary carriages can easily run at speeds of more than 20 kilometers per hour. The only problem is the brake problem.
Marin planned to study the simple foot-mounted brake system in later generations so as not to brake with the left hand and pull the reins with the right hand, but the result was that neither side could be done well...
Moreover, Malin found that after running down 3 kilometers, the horse pulling the cart was not tired at all, and he looked very energetic.
No wonder, when the speed of the carriage is increased, the inertia of the carriage and the small friction coefficient on the road surface make the force required for the horse to pull the carriage much smaller. On the contrary, when the horse wants to slow down, it is often pushed forward by the inertia of the carriage. Therefore, the horse pulls the carriage and walks on the cement road, which saves a lot of effort than on dirt roads and cross roads. In this way, the distance of the carriage continuously travels is much longer than on other roads. In this way, the average distance of the carriage travels by an average of a large distance. It is not a myth, even twice.
It would be amazing for ordinary carriages to run 100 kilometers a day on ordinary roads. Because after a carriage runs for an hour, it would have to stop and rest. It would not give people a rest, but a horse would rest. Otherwise, the horse would be exhausted. In ancient Roman times, on the Roman Avenue, stagecoaches could only run 160 kilometers in 24 hours, and they had to rest and change horses in the middle. Otherwise, the horse would not be able to bear it.
