Three Kingdoms: Opening War Strategy System

After the Liangzhou army in the northwest captured the Western Regions Kingdoms, the Dawan State and the Wusun Kingdom, it stopped the momentum of external expansion and gradually slowed down the military deployment that encroached on the enemy countries.

Because after seizing so much land, they need to spend manpower, material and financial resources to govern and develop and build.

Otherwise, it would really be empty Depot Mountain and I don't know how to use it!

The same was true of the Liaodong Army in the northeast, and generals such as Huang Zhong and Xu Huang, and civil servants such as Pang Tong, had been developing and building after capturing the various Guo Jia of the Yin Kingdom.

The materials of the Yin Kingdom were gradually mined, some were transmitted back to the Great Han, and some were realized on the spot.

The Union State Army and the Youzhou Army in the north are also managing grasslands, exploiting farmland and cultivated land, and exploiting forest and natural resources.

Li Dian and Lejin in the southeast also suspended their offensive routes against Java and Malacca, and instead worked hard to develop the Luzon islands.

The Jiangdong Army in the southwest, Zhou "883" Yu, Lu Su and other civil ministers, Sun Ce, Huang Gai and other military generals, are administering the countries in the Mekong River Valley.

At the same time, a naval base was set up in the Andaman Sea.

In the same southwest, the Yizhou Army and the Jingzhou Army who are now in the Shan State are still looking for countermeasures to open up the way to the Shan Country while governing the Shan State.

The ancient forest landscape is undeveloped and in a state of wilderness, especially in the Shan country.

It is full of tropical rainforests, as well as large and small mountains and rivers, which is very inconvenient for development and construction.

Even survival is very difficult.

If it weren't for the generals of the Yizhou Army and the Jingzhou Army, they all received ability bonuses and their physical qualities were different from ordinary people, otherwise it would be difficult to survive here for a long time.

Just a humidity, as well as a poisonous miasma, is very uncomfortable.

However, they did not give up this only way to the west, and this was also the only way for their Yizhou Army and Jingzhou Army to make meritorious achievements and wait for the generals.

The garrisons of these states and counties are the military deployment of today's Han military headquarters.

After they captured the strategic places in the surrounding areas, they chose to rest and recuperate to govern these places in preparation for the later Han to march into the world.

......

The Han army has been working hard to expand its territory, and those civil servants have not been idle, and have been governing the livelihood arrangements of the prefectures and counties of the Great Han.

Those scientists in the Hanke Academy are also not idle.

After decades of research and manufacturing, the steam engine finally came out.

Of course, in fact, the experimental products of the steam engine have been available for a long time, but the efficiency is not up to standard, and it is not as fast as the manual one.

However, the emergence of the steam engine represents the evolution of the beginning industry to the mechanical industry, that is, the reform of replacing manpower with machines.

Therefore, the research has not been abandoned, and has not been left behind. Until recently, there was finally a new breakthrough.

The efficiency of the steam engine was already comparable to the speed of a horse-drawn carriage.

When Liu Chen learned the news, he rushed to the Hanke Academy as soon as possible.

Together with Guo Jia, Xun Yu and Xun Yu, as well as Zhao Yun, Dian Wei and other important ministers of civilization and martial arts, all flocked to the scene.

"Your Majesty!"

When Liu Chen arrived, the whole of the Hanke Academy immediately saluted respectfully.

Liu Chen directly waved his hand to interrupt these red tape, and asked eagerly: "Take Xu to see the research results of the steam engine." "

"Yes!"

The group immediately went to the research and development park of the steam engine, and Liu Chen finally saw the current model of the steam engine, all kinds of them.

Some have been equipped on a train, and the ground is covered with rails, which are slowly running around the tracks.

Of course, this train has only one model style, which cannot be compared with the dozens of trains in later generations.

But it is already possible to show the movement of the steam engine, which converts the energy of steam into mechanical energy.

It is also installed on the loom, so that the machine runs automatically, eliminating the convenience of labor.

There were also ships mounted on battleships, propelled by steam engines, replacing the role of sails.

A variety of varieties to fill the R&D park of steam engines.

When Liu Chen and the Wen Chen martial generals behind him saw this scene, they were amazed!

They come to the Hanke Academy every year with Liu Chen, but the progress of steam engine research and development last year has not been so fast. (Read violent novels, just go to Feilu Fiction Network!) ）

If we talk about the steam engine we saw in previous years, it is as slow as a snail, and it is not as efficient as manpower.

Then last year's steam engine can already reach the slow speed of people.

And the current steam engine workmanship is completely comparable to the animal husbandry power such as horse-drawn carriages.

If it continues, it is only a matter of time before it is replaced.

"Can the speed of this steam engine be accelerated?" Liu Chen asked with some doubt.

Whether it was a train on the rails, a loom, or a steam engine on a battleship, the speed was very slow.

"Of course you can!"

The head of the Hanke Academy smiled lightly and waved his hand, and immediately a soldier stepped forward to operate....

The steam train, which was moving slowly on the tracks, gradually increased its speed, and most importantly, several soldiers boarded the train with Hanke bachelors.

This means that steam trains can carry people!

Hiss!

The sound of gasping for air sounded!

"This steam train, can carry people? The speed looks faster than a horse-drawn carriage! Guo Jia said with some shock.

The person in charge of the Hanke Academy said with a smile:

"We have tested that steam trains can reach a maximum speed of 75 km/h, which can completely replace horse-drawn carriages for long distances."

"Can this steam train run without sleep?" Zhao Yun asked in surprise.

"Exactly!"

The person in charge explains: "But there is a need for manual operation and supervision, and we are still commissioning EMMM safety valves.

Mainly using the lever principle and spring pressure adjustment..."

The person in charge even said several professional terms and terms, and everyone did not understand it. Of course, these are all court bosses, even if they don't understand, they have to pretend to understand very well.

Liu Chen asked with some doubt, "How did you solve the sealing problem?" "

According to Liu Chen's cognition, the difficulty of manufacturing steam engines is rubber, and rubber is only available in South America. Or extracted from oil.

Either way, it is not something that today's big man can do.

"Your Majesty, we use shaft sealing technology to seal with a toothed structure cross 1.6, and the joints are padded with brass and tung oil, etc..."

This person in charge of the Hanke Academy once again said a lot of nouns, and Liu Chen was a little embarrassed in his heart, and he had to calm his head.

In fact, in the eighteenth century, when Europe invented and improved the steam engine, rubber was not even used.

During World War II, European countries embargoed rubber against Dego, and it even used hemp rope and tung oil to seal it.

Of course, that's not the point!

Today, it is only the third century of the Great Han, who can already manufacture steam engines, and can already be put into use, gradually replacing manpower.

That's the point!

"Good! Very good! The research and development of steam engines of Hanke Academy of Sciences made Xu very satisfied! R&D personnel are rewarded! "

Liu Chen was overjoyed and waved his hand directly: "After the safety valve problem is solved, it will be put into use directly." The test site was chosen within the Jingshi Division! "。
