Su Bo nodded: "The young owner wants to build a 'rail road'?" ”

Liu Bei was stunned: "What is the track?" ”

Originally. In the Qin Dynasty, there was a straight road with wooden rails! The carriage galloped on the wooden tracks, and the distance of the sleepers just controlled the speed at which the horse galloped. In this way, the arrival time between the stations can be precisely controlled.

The principle of the pre-Qin rail road is no different from that of the later railways. It's still a double line, but instead of being pulled by a locomotive, it's powered by a horse!

Of course, the 'rails' of the First Emperor are certainly not cast in iron. And laid with wood. The wood used for the track is hard and has been treated with antiseptic treatment, and it is still intact today.

However, most of the sleepers have rotted and have obviously not been embalmed. The material is not as hard as the track, but its general appearance can still be seen.

It is said that the roadbed is very strong, and the sleepers are laid on the roadbed. The softer material of the sleeper is not only to reduce the amount of work, but also to broaden the source of wood, but to choose it intentionally. Softer sleepers can be closely combined with rammed very hard roadbed. This makes the track smooth and the car can travel fast on it!

And the distance between the sleepers, dark and horse steps in tune. Once the horses are on the tracks, they can't help but gallop all the way. It is almost impossible to stay (the horse must land exactly on the sleeper with every step, otherwise it will break its hooves and die). There is another transfer station along the way. When transferring to the track of the post station, the sleepers are filled with wood and flattened, turning into a boardwalk, and there is no longer a partition. With a solid foot, the horse can gradually slow down and stop. Then the horses will be replaced by a special person and continue to gallop. In this way, the relay is extremely efficient.

Since the use of rails, friction is greatly reduced, so it is possible to pull a large number of goods at once. At that time, it was the most horsepower-saving method.

It is said that one day and one night can travel 1,200 miles!

This is more than double the speed of 600 miles of expedited. It is no wonder that the First Emperor was able to manage such a large empire without having to divide the feuds. And often launch large-scale military operations with hundreds of thousands of people at every turn!

This logistics is too powerful.

Pre-Qin ...... Is this really the case?

Su Bo said that there are relics in Nanyang. Why don't you ask someone.

Liu Bei found Huang Xu.

Huang Xu said that in the mountains of Nanyang, there is indeed a 'rail road' of the Qin Dynasty!

Liu Bei was silent for a long time.

Your Majesty the First Emperor, wouldn't you have traveled back in time?

In other words, Qin Zhidao, if all have laid this track. Think about how powerful the former empire must have been! At the end of the Qin Dynasty and the beginning of the Han Dynasty, the princes fought in a scuffle, and most of the tracks on the gallop road were destroyed. Later, Gaozu divided the world, and the states and counties all had granaries and arsenals. Troops can be sent nearby, so the rail route for large-scale transportation is useless. It has not been reproduced since.

However, if you think about it again, 'cars on the same track' at that time. Once the war starts, the scene of the world's carriages and galloping tracks should be so majestic!

O Gaozu!

In this world, is it a fluke to win?

Liu Bei couldn't help but let out a sigh of relief.

The only difference between the track designed by Liu Bei and the pre-Qin rail road is that it is made of iron.

Don't think about the railroad that runs through the world. Let's not talk about the current production of iron. It is paved on the road, and soon it will be torn down and used for other purposes.

However, in Xilinyi, it is still possible to build a railway track around the wall.

But when Su Bo calculated, it was still a huge amount of money.

It doesn't matter, the young prince can bear it.

Suber said that the rails were best cast with 'gray iron'.

Although the hardness of 'gray iron' is slightly lower, the brittleness is also small. Cutting, wear-resistant, and slippery are all very good. Nowadays, the axle is mostly gray iron casting. Liu Bei doesn't need to know details like this. Just leave it to Sub to complete.

Sleepers are easier to do. There are wild forests all around, and now they all belong to Liu Bei. Cutting down sleepers, and then doing antiseptic, can be very useful.

The things in Xilinyi are another fresh topic after the martial arts field.

Determining the size of the track, Liu Bei then began to design the car building.

In other words, how many kinds of pavilions are there in Lousang?

Watchtower, warehouse building, city building, place building, heavy building, bridge building, pavilion building, ship building. Now, there will be a car building again.

It really lives up to the reputation of "Lou" mulberry.

The car building is similar to the ship building. It is nothing more than the hull that served as the base, and changed it into a carriage. Except for a set of movable vehicle-mounted double Weng septic tank, a water tank that is enough for a family to need for several days, and iron-clad doors and windows that can be fully closed into a box, it is no different from an ordinary pavilion.

The same is made of salted wood from Liaodong. Enameled iron, sufficient for fireproofing. The doors and windows open and close similarly to later motorhomes. On the top floor, there are also prospective buildings, women's walls, etc., which can be shot from a high position.

On the lower level of the room, there is a manual lever for the rail car. Just move the lever up and down, and the building can be on the track on its own.

Under the carriage, there are baffles on all sides, almost flush with the ground. In addition, the grass in the city is deep, and from a distance, it is no different from the heavy building standing in Lousang. No one would have expected that these iron-clad wooden buildings would be able to move back and forth!

Because it's all wooden. The building was built very quickly.

The prototype was soon built by a good craftsman led by Suber. The compartment was nailed with leather on all sides, and the floor was covered with carpet, which was indistinguishable from a tent. Wulian tried to sleep for one night, and her whole body was healthy and comfortable. That's called a sweet. He lifted the plank again and drove the rocker. The car building can move back and forth!

It's really suitable for nomads! This impressed Liu Bei.

In fact, Liu Bei can understand Wulian's persistence. When people go out, they often take a sip of their homeland, which is what it means.

Liu Bei has fulfilled his promise. Wu Lian then ordered the Yiluo people to move into the car building and 'move'. In the eyes of the Wuhuan people, a house that can be moved is safe.

Of course, this so-called 'security' is more of a psychological factor. Nomads, migrating with the grass. It's a matter of habit. Tether them to a fixed house, and even if the house is beautiful and strong, they will feel uneasy.

Liu Bei can completely understand.

After the beginning of autumn, there is a boat sailing into the water of the White Lake.

In addition to the Tian clan people who are familiar with each other, there is also a pair of mother and son in the boat. It is said to come from Huang County.

Words, to be attached to the young prince.

It is a pair of weak mothers and young children, and the guards do not suspect him. Then the floodgates were raised and the water bars were put in.

Tian's steward is familiar with Geng Yong. This brought the mother and son into the market building.

Along the way, the water pavilion is full of buildings, row upon row, stretching endlessly. In the middle of the boat road, pedestrians rub shoulders one after another, the streets and alleys are bustling, the traffic is busy, and the prosperity is endless. There are also many unknown heavy weapons scattered all over the place, presumably with their own functions.

Geng Yong was Liu Bei's first retainer. He does his best on weekdays and can be called virtuous. However, he also knows that compared to the lord Liu Bei, he is not good at understanding people. I heard that the mother and son came across the sea, and I thought of the tsunami in Huangxian County a month ago. This is clear.

Then he smiled kindly: "The two of you came from afar, and it was very hard to travel all the way. You might as well go to the guest house for a while. Wait for (Geng) Yong to show the lord first, and then make another arrangement? ”

"So, Lord Lao." It was not the mother who spoke, but the teenager.

Staring at the young man's shining eyes, Geng Yong remembered the first time he met Liu Bei in a trance. Since ancient times, heroes have come out of youth. There are Ganluo and Qin Wuyang in front. Today, there is Liu Bei, running for the cow. How do you know, is this non-young talent in front of you?

Geng Yong didn't dare to slack off. Ordered someone to send them to the guest house, chartered a fine house, and arranged their daily life to calm their hearts.

After his subordinates find out the origin of the assassination, it is not too late to report Liu Bei.
