The emperor wants to take a car to Chengtian Mansion, so what else can I say? No matter how much I do, I have to make it.

Wang Xuan stopped talking nonsense and started to take people to make equipment.

In fact, the equipment for manufacturing steam engines is nothing more than drilling machines and grinding machines, because the copper pipe that connects the steam is similar to the gun barrel, and the manufacturing method of steam pistons is also somewhat similar to that of the gun barrel, but the requirements are higher.

Of course, Wang Xuan only knew how to build these two equipment, and he could not build other milling machines, boring machines, etc., so he could only do something about these two equipment.

Yang Cong was not idle either. The professor's disciple had already spent too much time. In addition, the development time of this steam engine has almost a year passed, and there is no trace of this steam locomotive.

He promised Jiajing that he would build a steam locomotive within three years, otherwise Jiajing would be really annoyed by his untrustworthy person.

The emperor's anger is not a joke, so hurry up and make it happen.

He took the initiative to design the rails and carriages, and began to build them day and night with the help of carpenters and blacksmiths.

This rail is not very difficult, it is just I-shaped steel. It can be made by finding a way to cast it carefully. With the current technology of the School of Physics, he doesn't even have to worry about casting. He just needs to draw a simple cross-sectional view.

After the rails are cast, there are not many places to be processed. Just try to smooth the two sides that come into contact with the wheel, and then make a few holes to connect the sleepers. Other sides basically do not need to be processed.

This car is a bit troublesome. The trouble is mainly at the bottom of the car. Don’t look at the few wheels below, there are actually many things. Not only do the wheels have to be designed and cast, but the connecting rods, axles, and steering devices between the wheels must be designed one by one.

As for the real carriage above, it is the simplest, just like building a house, except that the main structure of the house is iron square and iron plate, rather than wooden square and stone.

He originally thought that the wheels, axles and connecting rods under the car were troublesome, but everything else was fine, but he never thought that he had just cast the rail samples and he was in trouble.

This trouble is not technical. It is quite troublesome to grind the two sides of the rails, but with a grinder, it only takes some time and labor. As long as you arrange more people and build more grinders, processing the rails will be quite fast.

The main problem is that the railway tracks consume too much iron. He processed a few of them slightly, and the iron stored in the School of Physics would consume almost the same amount.

Of course this is not possible. You must know that the track he is making is only one meter long. Even if it is a single-driving lane, it takes thirty rails to be a distance of one mile. The capital is nearly two thousand miles away from Chengtian Mansion in Huguang, and requires 50,000 or 60,000 rails. The demand for this iron is not a small part.

Nowadays, salt and iron are controlled by the court, and they are not something you can buy with money. There is no such thing on the market.

In desperation, he had no choice but to go into the palace again to find Jiajing.

His entry into the palace at this time once again aroused Yan Song's alert, because his disciple Li Chunfang had just won the top scorer in high school. If he took advantage of the opportunity to make a comeback at this time, I'm afraid Jiajing would agree without thinking.

Jiajing was naturally very happy when he heard that Yang Cong was coming. This kid is not simple. He can do whatever he wants. He can defeat the Tartars, eliminate pirates and Japanese pirates, and recover Annan. There is nothing he can't do. He even teaches the top scholar in high school when he goes to run a college!

To be honest, Jiajing wanted Yang Cong to come back and continue to work in the court at this time. Unfortunately, there was no suitable position at this moment. Otherwise, Jiajing would probably take the initiative to find Yang Cong.

Now Yang Cong actually came to him, so that was naturally the best.

After the monarch and ministers greeted each other, Jiajing said kindly: "Qingfeng, I didn't expect that you were so good at teaching. Li Chunfang, Chen Lian, Yang Jisheng, one top scholar and two top players. I was shocked when I heard that they were all your disciples."

Upon hearing this, Yang Cong hurriedly said modestly: "I dare not take credit for me. The reason why they can get such good grades is mainly because they study hard and hard, and I just supervise them."

Jiajing smiled and said, "There are so many scholars in the world, and there are not 100,000 people who work hard or 8,000. Why haven't I seen a few people who have done well in the exam? Okay, don't be humble. By the way, you come to find me. Are you unable to stand the loneliness and want to come out again?"

Yang Cong shook his head repeatedly and said, "No, there is still a lot of things happening in Weichen Academy, and I'm afraid I don't have time to come out to work for the time being."

Upon hearing this, Jiajing said regretfully: "Oh, that's the case, then why are you looking for me?"

Yang Cong quickly explained: "Your Majesty, that's right. I didn't tell the emperor last time that the fire of the five elements can also push the cart of thick gold. After hard research, I finally came up with a feasible method. However, this method requires a lot of iron and stone, so I want to ask the emperor to give some iron and stone to make the cost."

Upon hearing this, Jiajing couldn't help but say surprise: "Oh, have you really thought of a feasible method? What method, how much iron and stone is needed?"

Yang Cong explained: "This method is quite complicated, so I won't talk about it here. At that time, the emperor will understand when he sees the real thing. As for iron and stone, I guess it will take at least five or six million kilograms."

Five or six million pounds!

Jiajing was shocked when he heard this. Why did the imperial court control iron and stone these days? It was because the traitors used iron and stone to make weapons to rebel. The swords, guns, swords and halberds did not have much technical content. Ordinary blacksmiths would build them. If someone used iron and stone to make weapons to rebel, wouldn't it be troublesome?

Of course, Jiajing did not suspect that Yang Cong wanted to rebel. The key is that the demand for iron and stone is too great!

You should know that ordinary weapons are only about ten pounds, five or six million pounds, which is enough to build weapons equipped with 500,000 and 600,000 troops.

Jiajing couldn't help but ask, "Why are you using so much iron and stone? Can you use it to pave the road?"

This was originally a joke because he couldn't figure out what he needed to do.

Unexpectedly, Yang Cong nodded seriously and said, "The emperor is wise, and the empress needs to use these iron stones to pave the road."

ah!

Jiajing couldn't help but say in surprise: "It seems that ordinary bluestone slabs are enough to pave the road, why use iron and stone?"

Yang Cong explained calmly: "Because this thick gold car weighs tens of thousands or even tens of thousands of kilograms, if it is directly on the road, the wheels will definitely fall into the ground and cannot get out. Therefore, Weichen wants to lay the railway tracks on the road in advance and let the thick gold car drive on the railway, so that there is no need to worry that the wheels will fall into the ground."

ah!

Upon hearing this, Jiajing couldn't help but be stunned: "There are nearly two thousand miles from the capital to Chengtian Prefecture. Are you planning to lay two thousand miles long railway tracks?"

Yang Cong nodded without hesitation and said, "The emperor is wise. It is because I want to lay such a long railway track that I need so much iron and stone."

Then there is nothing I can do, I can only give it to.

Jiajing thought about it for a while, and finally nodded and said, "Okay, just transfer it from Xuanfu Town. You happened to have opened an iron ore there at that time, and a lot of storage there have been there now.

It seems a bit troublesome to allocate from Jizhou Town, but it is better than going to mine again.
Chapter completed!
