...

Not long after Li Yan entered Bianliang City, he gave the Chinese Academy of Sciences a plot of more than [-] mu of land not far from the imperial palace.

At that time, Li Yan's actions made people dumbfounded.

You know, this area was prepared by Zhao Ji to expand the palace for himself.

Who would have thought that Li Yan would give all the tens of thousands of acres of land to the Chinese Academy of Sciences?

More importantly, who knows, what does the Chinese Academy of Sciences do?

When some people pass by the Chinese Academy of Sciences, they often hear some huge and weird sounds, such as the breathing sound of "wheeze, wheeze", strange screams like "wuwuwu", etc...

Because of this, some people speculated that Li Yan raised one or a group of mythical beasts or monsters in the Chinese Academy of Sciences.

Some people also speculate that the reason why the Chinese army is invincible in all battles is because of the help of these mythical beasts/monsters.

These people's speculations are actually not without any basis.

In addition to the strange noises coming from the Chinese Academy of Sciences, the emperor Li Yan ran to the Chinese Academy of Sciences every now and then, and stayed there for most of the day.

Some women in Li Yan's harem couldn't help but said sourly: "This Chinese Academy of Sciences is almost becoming the second home of the official family!"

The common people guessed that Li Yan went to the Chinese Academy of Sciences to personally feed the beasts/monsters and connect with them so that they would not rebel or even devour the Lord.

This also added a lot of mystery to Li Yan invisibly.

In this feudal society, this can actually strengthen Li Yan's rule.

Of course, the Chinese Academy of Sciences is not a place where Li Yan raises mythical beasts/monsters, but a national scientific research institute chaired by Li Yan himself.

As for those strange noises, of course they were not made by mythical beasts/monsters, but by the train developed by Li Yan himself.

When it comes to this train, we have to talk about steam engines.

In fact, as early as a few years ago, Li Yan, Liu Huiniang, Bai Varhan and others had already developed the earliest steam engine.

This is actually not difficult, even without Liu Huiniang and Bai Varhan, the two mechanism masters, with the theoretical basis provided by Li Yan, just find some people who are proficient in mechanism production, and you can build the earliest and simplest steam engine.

But the steam engine is easy to build, but it is difficult to apply it to industry.

At the earliest time, Li Yan wanted to put the steam engine directly on the ship, and wanted to build his own steel fleet.

But until now it has not been completely successful.

Later, Li Yan proposed the concept of trains.

The Chinese Academy of Sciences began a two-pronged approach.

During the development process, under the leadership of Li Yan, tens of thousands of scientific researchers made repeated improvements to the earliest and simplest steam engine.

Separate condensers, a heat insulating layer outside the cylinder, oil-lubricated pistons, planetary gears, parallel-moving connecting rod mechanisms, centrifugal governors, throttle valves, pressure gauges, and other technologies have been overcome one after another.

Finally, in the middle of last year, the Chinese Academy of Sciences developed the world's first industrial steam engine, which was more than three times more efficient than the earliest and simplest steam engine developed by Li Yan and his colleagues.

At that time, the earliest and simplest locomotive also came up with a plan.

This locomotive, Li Yan and others originally wanted to do it in one step, that is, directly use steel to develop it.

But this difficulty is really too great.

In the end, Li Yan and others could only settle for the next best thing, mainly made of wood, and only used steel to make its core area.

But even so, the difficulty is still very large.

Fortunately, there is Li Yan, a person from later generations, who guides this group of people who are willing to study.

Li Yan successively proposed concepts such as foundry, annealing, and polishing (in fact, these technologies already existed before that, but they were not used in industry), and Li Yan even led people to manufacture the earliest lathe All in all, Li Yan's military internships when he was a soldier were not wasted at all, and almost all of them were used.

More importantly, Li Yan can practice steel, which is the basis of industrialization.

The most important thing is that Li Yan's vision is far beyond that of people of this era. Often, a small idea of ​​his can wake up tens of thousands of researchers, and then make a big step forward in research and development.

Reduced section said.

After countless efforts by countless people including Li Yan, the world's first locomotive was finally developed.

And today is the day when the locomotive is tested.

On such a day, how could Li Yan, who has made great contributions to the development of the train, not come to witness it in person?

Therefore, Li Yan came to the Chinese Academy of Sciences early, and then together with all the scientific researchers looked at the big, stupid and ugly locomotive in Li Yan's view, and the six railroad tracks neatly arranged around the Chinese Academy of Sciences.

Speaking of this rail, there is also a story.

When determining the width of the rails, the researchers of the Chinese Academy of Sciences dared not make decisions without authorization, so they asked Li Yan to make a decision.

Li Yan clearly remembered that the rails of later generations were 430 millimeters, so the first idea was to give the Chinese Academy of Sciences this value.

But the problem is that the current unit of length is different from that of later generations.

I won’t talk about the unit of length before Dazhong, it’s almost always the same, and it always changes.

The length unit of Dazhong Dynasty was forcibly determined and enforced by Li Yan.

To this end, Li Yan also held a very grand ceremony.

At that time, Li Yan took a step in front of 10,000+ people, and defined that step as "one meter" - this unit of length is also called "Yanmi".

Afterwards, Li Yan publicly announced that this was the unit of length for his regime, and stipulated that one meter equals three feet, one meter equals ten meters, one meter equals one hundred centimeters, one meter equals one thousand millimeters, and three meters equals one foot. , 1000 meters equals one kilometer.

Even now, when Li Yan took that step, he was still in front of the Liaodong Palace in Seoul - there was a master Roman sculptor who carved a stone statue for Li Yan, and that stone statue replaced Li Yan and kept taking that step.

Li Yan's step is determined that it is impossible to be equal to one meter of later generations without any deviation.

Therefore, even if Li Yan gave the Chinese Academy of Sciences a value of 430mm, it would never be equal to the length of the train track in later generations.

Later, Li Yan figured it out, why should he worry about the width of the train tracks in later generations?I am the founder, and it should be the people of later generations who follow my own footsteps.

In the end, Li Yan repeated his old trick, took two steps, and stipulated that this was the width of the rails.

Ordinarily, the two steps Li Yan took should be two meters long.

But Li Yan's two steps were a bit small, and the result was only 870 six millimeters.

This becomes the fixed width between the rails in this world.

By the way, before developing this locomotive, Li Yan and the researchers of the Chinese Academy of Sciences had already developed a steam locomotive, that is, a car that can run under the drive of a steam engine. The speed of the car is four to five kilometers per hour, faster than people walking Going slowly and not turning corners.

But even so, that steam locomotive still brought great hope to Li Yan and tens of thousands of researchers, especially the latter.

This is why Li Yan and tens of thousands of researchers were able to develop the train.

And this moment is the moment to witness the miracle...
