The prototype of the steam engine has been released. In the last few days, the design communication and exchanges between the shipyards brought by Zheng He were almost day and night, and gradually they had a direction.

Actually, it's not difficult.

Based on the current large ship Zheng He went to sea, structural changes were made.

It's simple to say.

However, only by actual operation can you know how difficult this is. It requires countless experiments, and each factor needs to be tested many times, such as draft. This problem needs to be derived from a series of data based on the experiment and then applied - this is not a big ship made of trees, but a steel, so the previous draft data was basically not referenceable.

Fortunately, there are professionals in this matter. At dusk, you only need to put forward ideas and then follow the professionals to sing flags and shout.

The days are rushing again.

Under the urging of dusk, Zhu Di asked Huang Yan to form a mission to North Korea. As for whether he would bring the tribute girl back in the end, Zhu Di did not give any instructions to see if the King of North Korea Li Fangyuan would be a human being.

Because of the reconciliation with Zhu Di, the Times Commercial Bank had no obstacles and vigorously entered the Urianha area. The construction of cement official roads was in full swing. My colleagues chose several important towns at dusk and set up a train foundry.

Shuntian one.

One is the Wuchang branch of nine provinces.

One is Xi'an, the ancient capital of the Six Dynasties.

Yingtian is one.

Four train foundries have started construction one after another and built production lines according to the design drawings - steam engines have been released. Although the steam engines needed by steel warships still require experiments, the trains need not be difficult. It can be finalized in a month at the latest.

However, because there are no serious railway tracks yet, there are only two railway tracks on all official roads, which are temporarily used as train tracks, so this train is mainly composed of three cars, so the requirements for steam engines are not high, and the main pursuit of speed is to be pursued.

In addition, the train casting reserves room for upgrades.

At the same time, Dusk summoned all the high-rise buildings of Times to Shuntian, held a meeting that lasted for several days. After discussing the railway track design drawings taken out by Dusk countless times, it was decided that Times Building will set up a separate railway company to conduct experiments first to see if the construction technology and technology can meet the requirements of enduring the weight of the train body of ten or even twelve and eighteen.

At the same time, the Times Commercial Bank sent a large number of outstanding geological personnel to survey geology nationwide, draw railway route maps, and prepare to start the construction of national railway network lines.

After the meeting was held at dusk, I went to find Zhu Di directly.

This matter...

Relying on the Times Business alone is a bit unsupported and requires stronger national strength, so at dusk, you have to find Zhu Di and let the Roads Department get involved.

Zhu Di was discussing the funeral of King Zhao with Li Qing, and Empress Xu was also there. When she heard that she was asking for a meeting in Dusk, she asked Li Qing to suspend it and asked Kang Ning to invite Dusk into the hall.

When I entered the hall at dusk, I found that Li Qing was there and Empress Xu was there too.

Suddenly I realized.

So he was a little embarrassed. He saluted Zhu Di first and then saluted Empress Xu. Zhu Di was exempted from the tribute, but Empress Xu did not. Looking at the dusk, he sighed for a long time and murmured that I treat you well.

I made you and the third sister a hand.

My fourth sister, I didn't say anything, and I married you.

Even Xiao Baoqing married into your Huang Mansion.

Why is the third brother still dead at your hands?

I felt guilty in my heart, not about Zhu Gaosui. If things happened ten thousand times, he would still kill Zhu Gaosui ten thousand times, but about Queen Xu. He sighed softly after hearing this, "Empress, I am sorry, some things are not something we want or not, but we are all driven forward by worldly affairs, and we can't help it."

Empress Xu was speechless.

Zhu Di coughed, "What's wrong with you?"

At dusk, he immediately took out the drawings and handed them to Corning. Zhu Di took them and took them, "This is your train. Why are there so many? There seems to be no big difference. It's just the change in the body of the car from three to more than ten."

Dusk nodded, "Because there are simple rails on the official road now, three-car trains can be used after they are built, but the load capacity is very small, and only more than a hundred people can be carried at one time. The function of transporting troops is slightly poor, mainly for cargo transportation. However, trains with more than ten bodies have huge loads. Once they are put into operation, there will be more than ten trains of 50,000 troops."

Zhu Di's eyes were bright, "Where is the speed?"

At dusk, "If the railway tracks are galloping continuously for twelve hours of day and night, it will probably be about 1,200 miles. After all, the safety of the simple railway tracks is not high."

Zhu Di was overjoyed, "One thousand two hundred miles a day?"

what does that mean?

It means that the army from Shuntian sent troops to attack Urianha. With everything ready, the army can only be deployed for one or two days before it can form a formation outside the Chen Jun Pass to kill the enemy.

This is something I never dared to think about before.

Even the Light Cavalry can't do it!

The most important point is that this is of epoch-making significance for support - the emergence of the train, and all the previous military tactics will be re-turned.

The Ming army had such mobility and could achieve the effect of crushing the enemy in almost any battle situation.

Invincible...

This is really invincible.

But Zhu Di obviously thought too well.

Twilight coughed, "Your Majesty, it's not that simple. Trains cannot be run casually. They need rails and coal as fuel supply. Therefore, this corresponding logistical support must now be prepared for the future."

Zhu Di nodded, "You talk about it in detail."

"The three-chamber train matter has been basically implemented, and you can gallop on any cement official road with rails. The problem is that the trains that have been raised on the body section require real railways - well, the railway is a railway track dedicated to trains, so it is called railways for short, which is more difficult than the construction of cement official roads."

Zhu Di waved his hand, "That's necessary to be repaired!"

Xun smiled and said, "Times Construction has established a railway company and is sending excellent geological personnel to survey the railway route map across the country. However, the problem still exists. Your Majesty, you know, this thing is very expensive. No matter how rich Times Commercial Bank is, it cannot support the construction of railways across the country, so this matter requires His Majesty to take action."

Zhu Di understood, "Then how much does it cost to build this railway across the country - well, the railway dedicated to trains do? "

Dusk thought a little, "The more manpower, the better. At present, the population of our Ming Dynasty has skyrocketed, and the demand for manpower is not large. Even if the local people in our Ming Dynasty are unwilling to build railways, we can recruit people from the Indochina Peninsula - to be honest, this is the best way, because at the current level, building railways will actually kill many people."

A fellow Taoist who dies will not die.

Otherwise, if I encouraged Zhu Di to attack the Indochina Peninsula, wouldn’t human resources also be of resource?

Zhu Di nodded, "Okay, where is the money?"

I had a headache at dusk. To be honest, how much does it cost to build a railway nationwide? Times Construction held a meeting for several days, but it didn't come up with a specific number. I couldn't even estimate the approximate number. Anyway, it must be astronomical numbers.

Because I haven’t built a railway seriously, I don’t know how much investment it takes per kilometer. Moreover, the cost will be different when building roads due to different terrain and soil conditions.

So he went to the big picture, "If you want to build a railway that runs across the country, I guess this project is impossible to achieve without hundreds of millions of silver."

Zhu Di took a breath.

Empress Xu on the side was shocked and inexplicably. She was like listening to the heavenly book. Is this something that humans can do?

Li Qing was also stunned, hundreds of millions of dollars in silver?

Just joke.

Kang Ning was dumbfounded. Even if you take the treasury to the sky, you can't afford so much money.
Chapter completed!
