Da Qin: The First Emperor was reborn and made me the crown prince at the beginning

The first year of Tianwu has passed like this.

And on the last day of the end of the first year of Tianwu, Yingchen carried out the annual sign-in.

Specify the check-in.

Finally, the technical drawing that Yingchen dreamed of, the Watt steam engine, appeared!

It should be noted here that the steam engine was not invented by Watt.

Before Watt, there were already steam engines in England.

However, Watt's most important achievement was that he improved the steam engine of the past.

In a word, Watt's steam engine was three times more efficient than the primitive steam engine that preceded it.

More importantly, this steam engine can be used in the industrial industry.

Watt's steam engines are not only widely used in the mining industry, but also in smelting, textiles, machine building and other industries.

Originally, Jenny's spinning machine produced more than ten times as many textiles as before.

The advent of Watt's steam engine caused the production of these textiles to skyrocket fivefold in just twenty years.

More importantly, Watt's steam engine could be used on ships and trains.

Its appearance heralded the arrival of the age of steam and the age of trains.

The advent of railways has undoubtedly laid the foundation for a modern country.

As mentioned earlier, there is a limit to the area that a country can control in an era.

Generally speaking, the place that the center can reach within seven days is the land of Wangji, and it is also the place where the entire royal city has the strongest control.

For example, Guanzhong in the Qin and Han dynasties.

For example, Zhili in the Ming and Qing dynasties.

And if the center can be reached in half a month, it is the core area of a dynasty's rule.

For example, Longxi, Hedong, and Central Plains in the Qin and Han dynasties.

And if the center takes a month to reach, it is basically a place where the rule of the dynasty is relatively loose.

For example, Jiangnan and southwest China during the Qin and Han dynasties.

For example, Northeast China, Mongolia and other places in the Ming and Qing dynasties.

And if it takes more than a month, or even two or three months, to reach the place, then it can basically only have nominal jurisdiction.

For example, the Western Regions and the land of Nanyue during the Qin and Han dynasties.

For example, Outer Mongolia and Tibet during the Ming and Qing dynasties.

This is actually the time and distance of information transmission, which increases the difficulty of domination.

To put it simply, if a place rebels, it will take several months if the center sends an army to fight it.

How could this place be stable?

This is still the same sentence, the economic base, determines the superstructure.

Unless it is a sub-enveloping system.

For example, the Mongol Empire.

Genghis Khan once proudly declared that it would take a year for his country, from any of the south, east, west, and north, from the border to the capital of Mongolia.

Although this is the pride of Genghis Khan, it is also the dilemma of imperial governance.

As a result, Genghis Khan was able to divide his vast empire into several equal parts and give them to his sons and cronies.

However, as early as the reign of Genghis Khan, there were already signs of fragmentation of the Mongol Empire.

In the last years of Genghis Khan's life, his eldest son Jochi did not come to meet Genghis Khan very often.

Of course, this is also related to the suspicion of Jochi's background.

Because when Jochi was born, his mother happened to be captured by the beggars.

That period of history is also the most painful history of Genghis Khan. (Read violent novels, just go to Feilu Fiction Network!) ）

So for a long time, the relationship between Jochi and Genghis Khan was actually quite tangled.

Even Genghis Khan's other sons did not recognize this eldest brother.

And "Jochi" in the Mongolian language, it has the meaning of guest.

And after the death of Genghis Khan, the Mongol Khanate soon fell apart.

After the death of Möngke, the last Great Khan of the Mongol Khanate, the Mongol Empire ceased to exist in name only.

Therefore, even the Mongol Khanate could not avoid the state of separation due to distance, let alone other dynasties and states.

But with the advent of trains and railways, all this can be declared a reality.

Because trains are able to move twenty-four hours a day, as long as the fuel is with the driver.

The speed of the train is basically as fast as a galloping horse, basically reaching more than 40 kilometers per hour.

In other words, theoretically, if the train runs all the time, it can travel a distance of 500 kilometers a day.

Then starting from the center of the empire, within half a month, it will be enough to cross the entire Eurasian continent.

Therefore, this is also the absolute weapon of Great Qin to rule the world.

What's more coincidental is that the steam engine that Yingchen got by signing in this time has the most primitive ones, some after Watt's improvement, and some after Watt's, which have continued until the beginning of the twentieth century.

From this point of view, it is worthy of being the product of annual sign-in.

Moreover, once this steam engine is used on a ship, the speed of the warship will be far higher than the speed of the sail-controlled warship.

And with the steam engine, humans were able to dance hundreds of thousands of tons of presses.

In this case, the steel produced is far from the supremacy of the steel refined by the ancient method.

......

With Yingchen signing in and getting the steam engine, a new round of changes began to take place in the entire Daqin.

The most important thing is that the first navy of Great Qin in Han Xin's hand is about to be reequipped.

When the periphery of Zheng He's treasure ship was wrapped with a layer of iron sheets, and then equipped with the steam engine that Great Qin had just invented.

It's nothing short of terrifying.

On the other hand, in addition to the construction of cement roads, the construction of railways in Daqin was also slowly put on the agenda.

In July of the second year of Tianwu, under the hard work of Xu Guangqi and Song Yingxing, two great talents and a group of Mo family children, after half a year of hard research, the first day of Daqin's steam engine, the Tianwu steam engine, was finally announced.

Of course, in the process of studying the steam engine, Daqin's various science and technology are also developing rapidly.

The emergence of a machine is often brought about by hundreds or even thousands of other technological breakthroughs.

On the other hand, with the drawings and various data of the steam engine signed in from the system.

Xu Guangqi, Song Yingxing, and the children of the Mo family were able to reverse various science and technology.

In this sense, it is a mutually reinforcing relationship.

Soon, a kilometer-long railway track appeared on the outskirts of Xianyang City.

And on this day, the Tianwu steam engine was also successfully loaded on a locomotive with six iron wheels.
