“Woo woo woo woo…”

"Huff, hufu, hufu..."

Li Qingzhao, who witnessed the locomotive running with his own eyes, couldn't help but say excitedly: "Run! Running! Officials, look, this train is really running!"

Compared with Li Qingzhao, a group of scientific researchers who had seen steam locomotives running and had repeatedly experimented many times were also very excited, but they were far less excited than Li Qingzhao.

Liu Huiniang looked at it for a while and said, "Officials, we seem to have successfully developed it, but... the speed of this train is countless times faster than what the official said, and it is much worse than that of the horse."

The speed of this locomotive is much faster than the speed of the previous steam locomotive, which can reach a speed of about fifteen or sixteen kilometers per hour, almost equivalent to the speed of a person briskly walking. Moreover, because of the rails, it also solves the disadvantage of not being able to turn.

It can be said that human civilization has taken a whole big step forward.

Of course, this locomotive is still a long way from being put into use.

But despite this, Li Yan was still very happy to see that under his own leadership, humans finally developed the train.

Li Yan said to Liu Huiniang, Li Qingzhao, Baivalhan and others: "Although it is still very slow now, I believe that in the near future, it will definitely change human travel! By then, I will have to cover all areas of Dazhong. No, I will cover all the world. By then, it will only take one day from Tokyo to Yanjing, only three or five days from Yanjing to Khmer, and only more than ten days from Yanjing to the distant West!"

After listening to Li Yan's enjoyment, Li Qingzhao wanted to say: "This is simply impossible."

But looking at the steel monster running not far away and thinking about the miracles that Li Yan has created in the past, Li Qingzhao couldn't help but think of: "Maybe there will be such a day," she said.

Sudden!

A strange sound appeared in the locomotive that was still running!

Li Yan and others all raised their hearts, and Baivalhan even ran to the locomotive and asked, "What's going on?"

Not long after, the person in the locomotive poked his head out and replied loudly: "The turning rod is broken. The wood is not good. It must be made of steel!"

Slowly, the train stopped.

The main scientific researchers, including Li Yan and Liu Huiniang, all rushed to the locomotive, and Baivalhan even rushed to the locomotive directly to check the current situation of the locomotive.

After checking the locomotive inside and out several times, Baivalhan and others got off the front of the car.

Baiwaerhan came to Li Yan and reported: "Officials, the train we developed should have been successful, but it still has many problems. The main problem this time appears on the transmission components. I have just carefully checked it. Not only did the turning rod break, but other wooden transmission components also have cracks of varying degrees. These transmission components must be made of steel."

This is actually not a problem. It is now the R&D stage. Using wooden components can greatly shorten the R&D time. After all, wooden ones are much easier to make than steel ones. After the development is almost done in the future, it is enough to replace them with steel ones.

Another researcher, the contemporary Mohist master (the head of the contemporary Mohist school), said: "The material of this component is not a big problem. The real problem lies in the steam engine. The direction of the official proposed that oil replaces coal as the main power of the steam engine is not wrong, but the heat burned by the oil is far greater than that of coal. The steam engine we developed cannot withstand this heat at all. I just carefully checked the steam engine on the train, and after running for such a short time, it has become hot. Therefore, even if the components are not problematic, our steam engine cannot last for too long. Therefore, the steam engine needs to be improved. In addition, I think that at present, using coal as the main power should be enough, which can greatly reduce the difficulty of our research and development."

After coming to this era, Li Yan realized that he really underestimated the ancients.

In fact, both media and oil have been discovered and started to be used in this era, even earlier.

The records that coal was widely used in production and life were recorded in the Han Dynasty.

However, at that time, coal was not called coal, but was called Annihilation, Shi Ni, Black Pill, etc.

There is a record in the Book of Han that "Yuzhang produces stones, which can be combustible as firewood."

There are still records in many documents that coal was used as fuel to smel iron during the Western Han Dynasty.

After the Han Dynasty, there were more and more records about coal, such as the "Yuzhangji" mentioned the use of coal to cook rice, which shows that the use of coal was already very daily at that time.

In addition to iron smelting, cooking, and the Southern and Northern Dynasties, there are also records that people used coal to keep warm at that time.

By the Song Dynasty, there was a major change in the use of coal. The Song Dynasty began to use coke to smelting iron, which was a very important and epoch-making invention in the history of metallurgy. Compared with Europe, China was several hundred years earlier. At the same time, the Song Dynasty was also the most effective era for the development and utilization of coal in ancient times, and it was an era for the large-scale mining and widespread use of coal in China. It was also in the Song Dynasty that "coal" officially became the name of coal.

Oil has also appeared long ago.

Shen Kuo, a few decades ago, wrote in his "Mengxi Bitan Magazine 1": "There is oil in Yan's territory. It was said that Gaonu County produced fat and water, which is this."

Shen Kuo was just the first person to record oil in words. In fact, the Chinese have long known about the existence of oil and started using oil.

Therefore, it was natural for Li Yan to use coal and oil on the steam engine.

only

Li Yan's thinking runs too fast, and Bai Valhan and Mo Juzi's R&D capabilities cannot keep up with Li Yan's thinking at all.

Take this steam engine as an example.

Baivalhan, Mo Juzi and others were able to use coal to start the steam engine. Li Yan told them that they could use oil to start the steam engine, which resulted in their steps being too big and they were pulling the eggs.

but

These are all trivial matters.

As long as the direction is correct, you can improve slowly.

Li Yan ordered Baiwarhan, Mo Juzi and others to immediately improve the locomotive and launch the second generation locomotive as soon as possible.

At the same time, Li Yan asked someone to lay the railway tracks out of the Chinese Academy of Sciences and pass through all the downtown areas of Bianliang City.

Everyone in Bianliang City felt a little confused about the sudden appearance of the railway tracks and did not understand what the court was going to do?

Until a few months later, a giant steel beast rushed out of the Chinese Academy of Sciences.

Seeing this, people all scattered and fled, thinking that the "big beast" was coming to harm people!

When people fled to the distance, they saw that although the "big beast" looked very scary, it seemed that it could only run along the railway tracks.

More importantly, there was a person standing above the head of this "big beast".

This person... turned out to be their emperor.

At this time, the Chinese Academy of Sciences personnel who were mixed in the crowd explained to the people: "This is not a monster, but a train. It can carry people and things. It was developed by His Majesty and our Chinese Academy of Sciences researchers..."

Those who had not been hit by this kind of steel beast were shocked after seeing the steel beast roaring by, and were all impressed by Li Yan, who invented it.

Not long after, the court launched another thing called "textile machine". This textile machine can spin many cotton threads at a time, greatly improving the efficiency of weaving. Moreover, the quality of the cloth woven by the weaving machine is better than that of hand-woven.

After a while, people from the Chinese Academy of Sciences began to ride a group of monster cattle under the guidance of Li Yan, and bicycles were born.

Slowly, an industrial revolution forced by Li Yan, composed of steam engines, coal, iron and steel began to break out...
