How long does it take for the 20,000 cavalry troops in the Tang Dynasty to reach two thousand miles away? At least fifteen days! Li Chengqian quickly gave a number in his heart! Because it is impossible for cavalry to set off directly without taking anything, food, supplies and supplies need to be carried, and even cavalry in a hurry cannot rush forward every day.

Otherwise, even if you arrive at the destination, you will not have any combat power. This is a huge gap. Fifteen days and one day... When they arrive, the daylily will be cold.

When the movement speed of the scenery outside the window remained stable, Li Chengqian and the others calmed down. However, looking at the scenery outside the window, everyone was not sure how to express it. At this speed, even if the war horse speed of the big man they were in was a little faster than this, it was not much faster.

The point is that war horses will be tired, and war horses cannot run so far with hundreds of tons of things.

"I understand what Chief Huo means. I'm afraid he wants to negotiate with his father to build this railway to the Tang Dynasty, and at least he needs to build it to Chang'an." Li Ke hesitated for a moment, and then said, "But I'm afraid the father may not believe such a thing, so Chief Huo Gang asked his elder brother to write this thought."

Li Chengqian nodded, and they also thought of this. Do they need such a thing? I'm afraid it's needed, because although Li Chengqian and the others don't know much about what technical crushing means, they know that if they don't have a train, the gap between them and the big man will become bigger and bigger.

The gap between the two is already very big now. If there is no train, think about the Han controls the entire territory, and the Tang controls the entire territory. The time gap between the two is too big. Even the so-called 800-mile rush cannot be faster than this.

The scenery outside the window was still moving backwards quickly. In just a while, they estimated that they had traveled at least dozens of miles, and were pulling nearly 500 tons of supplies forward. If a carriage was used, how long would it take for such a large amount of food? At least 800 carriages to travel a day, and they only had half an hour now.

This is the gap. For example, the transportation of materials such as grains, the consumption of personnel on the road is also huge, but such transportation methods will reduce the loss of these grains on the road to the limit.

Not only grain, but also other cloth, and various materials will be transported faster, which is of great benefit to the operation of business.

"You all want to observe, especially Huai Liang and Baoqi. You are experts in this regard for military applications, so you must give me advice on this."

"Yes!" Cheng Huailiang and the others agreed immediately.

"Everyone, you guys can think of it. You can tell me about the plans for trains in all aspects." Although Li Chengqian had various ideas in his mind, he was the only one after all, and he might not be thinking about it so much. If so many people think about it together, there would be no big mistakes.

"Yes." Everyone else nodded.

Li Chengqian and the others soon stood up and began to observe around them. At this moment, in front, behind and even in the middle, Lu Feng and the others were constantly busy, mainly observing the operation of the train's steam engine and other aspects. If there was no problem, they were not going to stop, but arrived directly at the Industrial City.

This is also the first time that the steam engine is fully operational under heavy load. It is not only for the locomotive, but also for the railway, and even the link components of each carriage, etc., which are the biggest tests.

Li Chengqian and the others have noticed that on both sides of the railway, every three kilometers away, there is a man in a uniform holding a green flag next to the railway, and there is a red flag in his other hand. So it looks like a red flag, it should be prohibited.

This was what Li Chengqian guessed, and he definitely didn't know the specifics, but no matter what, Li Chengqian still needs to observe these details carefully, and he was also thinking about what benefits the entire railway would get if the railway was built to the Tang Dynasty.

There are actually many problems with steam trains in history, but what is different from Dahan is that the casting process of Dahan far exceeds the casting process of steam trains in history at the same time. It was not until the 20th century that it was estimated that it was similar to the casting process of Dahan now.

But for now, Dahan's application of power is still in the theoretical laboratory stage, and is currently conducting large-scale research and development and use, but it is estimated that it will be put into use soon.

With Huo Gang, there is no need to take detours in power research, just conduct alternating current directly. In this regard, you only need to constantly teach them to learn. A new group of children who have started to receive education in these aspects from an early age. In a few years, when they grow up, they may be the first group of children who truly receive modern education in the Han Dynasty.

They will also support the entire Han Dynasty's next article.

Time flies very quickly. Just over an hour. After more than two hours, the black smoke from the industrial city in the distance was clearly visible and was constantly approaching, and the train had begun to gradually slow down.

Li Chengqian looked at the sun in the sky. In just over an hour, the road of more than 200 miles was completed. Nearly 500 tons of supplies were transported with them. If these 500 tons of supplies were transported by carriages, it would take about 800 carriages to transport for two days, and it would take at least ten hours a day to walk.

The train only takes more than two hours. If possible, at least 5 trains can be taken every day. If these patrol members also start patrolling at night, then these trains can even start at night because there is no place to see the road on these tracks, and you just need to keep moving forward.

In fact, the railways of this era are indeed the same. What is different from later generations is that it is unlikely that the railways of this era will hire all personnel to monitor all railways, so a barrier remover is installed in front of the locomotive, which is only a little higher than the railway track. If there are trees or other obstacles falling on the railway track, the barrier remover can directly shovel the obstacles without affecting the operation of the train.

When we arrived at Industrial City, everyone got off at the railway station of Industrial City. There were more large buildings around it. This was the first time that Li Chengqian and his friends entered the interior of Industrial City. Not to mention anything else, the chimney, which was at least dozens of meters high or even hundreds of meters high, shocked them.

How huge should the fired things beneath such a high chimney? And you can see from a distance that the huge steel structures of more than ten meters high were forged. If the craftsmen of the great man were to build this huge steel column structure, the more than a dozen craftsmen would probably not be forged in less than a year.

Even forging cannot be so neat, because when constructed, how can such a huge steel column structure be turned over? How great is this force required? And they don’t know how the so-called gantry crane is forged like this.

They really don't know the principles and so on.

Standing here, Li Chengqian suddenly felt a kind of hesitation. It was a kind of thing. He was obviously standing in a treasure house, but he didn't recognize the treasures around him at all. At this time, Li Chengqian suddenly realized why the education of the Han Dynasty did not teach the so-called Four Books and Five Classics, the words of the saints. Under such an industrial system, what is the use of the words of the saints?

Can the Saint Words build a train? Can such a huge industrial city be made?

It is not possible that the craftsman system of the great man was published in the entire newspaper. They have read that newspaper. The craftsman status of the great man is so high that when he reaches his peak, it can be said that it is no different from Fang Xuanling and Du Ruhui. Although there is a difference in specific power, there is really no difference in social status and other aspects.

Even higher than Fang Xuanling and others! Because according to the newspaper, prime ministers like Fang Xuanling and Du Ruhui can be trained in batches, but a top craftsman, oh, the man calls him a scientist, a top scientist, that is not trained in batches. Every top scientist, talent, hard work, luck, etc. are indispensable.

Therefore, every scientist is given by God, and the newspapers of the Han Dynasty are promoted in this way. Therefore, the Han Dynasty gave these scientists a very high status, so the industrial city of the Han Dynasty has today.

And not only that, now all the people, merchants, and even some large families in the Han Dynasty hope that their children will study and become a marked scientist one day. Such an atmosphere is not available to the Tang Dynasty. As for the words of the Four Books and Five Classics that the Tang Dynasty truly valued, the words of the saints such as the Four Books and Five Classics are just the basis here.

Some people may study in depth. The great man called these people literary writers, but most people did not learn these. Most people would learn different disciplines such as mathematics, physics and chemistry, and the great man called these disciplines science.

Here, Li Chengqian felt the prosperous era in the Spring and Autumn Period, where hundreds of schools of thought flourished and hundreds of schools of thought! Now the Han Dynasty has already had this trend. And the Tang Dynasty... Li Chengqian suddenly understood Li Shimin a little, because the Han Dynasty and Huo Gang could be said to do whatever he wanted, but the Tang Dynasty and Li Shimin could not do this, at least Li Shimin of the Tang Dynasty could not do this at present.
