咣 Dang 咣 Dang 咣 Dang 咣 ... The noisy sound accompanied by the vibrations beneath him made Ren Baqian feel that he might fall apart at any time.

In the open space surrounded by a fence outside Lancheng, a circle of 400-diameter rails was laid on it, and a train pulling two wooden carriages was running along the rails, making a constant noise.

And Ren Baqian, the Empress and others were in the second compartment behind the train, and the thick smoke coming from the locomotive came along with the wind ...

"It's much faster than an ox cart," said Shang Shujiyan of the Ministry of Justice, feeling the wind blowing.

"And it's much smoother," everyone said.

With the roads of this world, coupled with wooden tires and shock absorption, even a car in the city needs to have a very strong hip, let alone outside the city.

After getting out of Lancheng, the speed of the ox cart is only slightly faster, it is a disaster, which can let you spit out all the internal organs.

"It just smells awful." Shao Nong Si Qing Yu Chang covered her nose.

"After all, there are advantages and disadvantages." Ren Baqian smiled, and then introduced to everyone: "This kind of train can reach 70 miles in half an hour, 140 miles in an hour, and can run up to 1,680 miles a day, from Lancheng to It only takes two days to protect the northeast government or the north government, and this is only the current speed. In the future, it can continue to increase, even double! "

"So fast? Does this thing need to rest?" Someone asked in surprise immediately.

"This is not a living thing, so you don't need to rest like a livestock. As long as you have enough coal, you can keep moving at such a speed." Ren Baqian explained to everyone.

"And this kind of train can pull a lot of cargo. The train made of metal has a load equivalent to about 60 carts. A trip can pull dozens of carts, which is equivalent to the load of more than 4,000 carts. You don't need to use so many people, and you don't have so much forage.

Not only can such trains carry a large amount of cargo, they can also be used to transport troops. In just two days, tens of thousands of troops can be sent to both the northeastern and northern capitals, which also saves a lot of time and food. Especially when there is war.

Both the speed and the load capacity are completely incomparable.

More importantly, with this thing, it will be much easier to rule the cloud country. No matter what happens on that side, you can respond to dispatching troops in a timely manner. A variety of materials can be shipped back to Izumo. "

"hiss--!"

Everyone took in the air.

Everyone may not be clear about the concepts of load and speed. But when it comes to the load of more than 4,000 ox carts, and two days, everyone immediately had a relatively clear concept.

You need to know that a horned ox is only over a thousand catties. As for the speed, it is even slower. It can go up to 100 miles a day at most.

In other words, a train runs for one day, which is equivalent to more than 4,000 ox carts for ten days.

The manpower, material resources and food needed for this is an astronomical figure.

Not to mention reduced time, even the ancients understand the value of time.

In this comparison, everyone in the field was trembling with emotion, one by one, as if they would be able to drive a train straight to half of the clouds tomorrow.

"The governor of Ren said what was moving and I was very moved. But you must know that the so-called railway tracks below alone consume more than 200,000 kilograms of steel, which is enough to arm 10,000 troops.

And from the foot to the cloud, thousands of miles, how much iron is needed? More than a million pounds! It is not necessary to have so much iron to empty Da Moshan, and the time required is even tens or hundreds of years. Tu Wan poured a basin of ice water directly on everyone and poured it from head to toe.

Everyone does not need to hold their fingers to count, just listening to these things under their feet actually consumes more than 200,000 pounds of iron, which is scary enough. Even more scary is the cost to spread from here to Izumo, that number has completely exceeded everyone's concept of number.

They always felt that number was inexplicably distant, as if it could never be completed.

Everyone stared at the map late, and then looked at Ren Baqian, not sure what to say.

"Isn't that impossible?" Someone sighed.

"No, no, no, my plan is ten years, connecting from Lancheng to Izumo, not to the northeastern capital." Ren Baqian waved his hands. "Listen to me."

"In fact, it is not as difficult as you think. Although iron ore is scarce in Dayao, it is not lacking in Izumo. As far as I know, there are seven iron ore mines in Iwun. I am afraid that there are still .

This railway is calculated at 4,000 li. According to the standard rail, 200 kilograms per meter requires 40 million kilograms of steel.

Even the smallest type of iron ore, one million jin of iron ore can be mined. According to the content of 50%, there are enough 50,000 jin of iron and steel, which is enough to build such a railway.

Larger small iron mines can build ten such railways, and medium-sized iron mines can build a hundred.

So you don't need to worry about the amount of steel consumed. Izumo has enough steel reserves to consume.

As for mining, that's not even a problem. As long as a prisoner of war digs ten pounds of iron a day, it is more than three thousand pounds a year. Izumo's iron ore is not Damosan. Adults don't think they can't even mine ten pounds a day by themselves. One hundred thousand prisoners of war can dig up the iron ore we need in two years. "Ren Baqian directly put aside the others and used numbers to calculate for everyone.

As for the mining of iron ore, that was not a problem at all in his eyes.

The people in this world are much better than the people in the world. If there are problems, there are so many masters who can solve them. If they do n’t work, they can also transport mining explosives, which is much more than the previous mining methods of the earth. , The difficulty has been reduced too much.

"And we can build a steel plant directly in Tohoku, Tohoku. After smelting in Tohoku, to lay a railway directly from there. Even if it fails in the end, those rails can be used for other purposes, but it consumes a little manpower and Just forage, it still consumes prisoners of war, we can still get a lot of steel.

If it is, then this is a matter of great success, and the Izumo area will be firmly in the hands of the empire. "

After Ren Fan said, everyone began to think deeply.

"Although I don't know exactly how much is needed, but the reason Ren said is correct." Qin Chuan scratched his head. "Master Ren must have better insights than the old man, and the old man thinks it works."

To know that this railroad track can really be realized, then the Ministry of Defense is also the beneficiary. The troops can be freely transferred. Thinking about it makes him feel excited, and he immediately speaks.

"The old man thought that what Ren said was true. If this happened, the entire Izumo area will be between His Majesty's palms, even if it is worth paying some." Shi Qing slowly said.

"Old man seconded." Kou Zhehai nodded.

"Master Ren's knowledge and ability, the old man knows." Tong Zhenye smiled, and then his voice turned: "But Izumo really has so much iron?"

"Sure, and certainly. Iron is one of the most common substances in nature. As long as iron ore is formed, the amount will not be too small. And I am speaking in the most conservative terms, and can be found at the level of Izumo prospecting. The mines are mostly open-pit mines exposed on the ground. The reserves and ore quality may be higher than I said.

Especially three of these iron ore are very close, and it is likely that a large iron ore is buried underground.

The location of these three iron mines is exactly where the soldiers from Zidong are now guarding.

As long as the front is pushed forward, these three iron ore will fall into our hands. "Ren Baqian said.

As soon as this remark was made, there was no remark about Tu Hong.

After all, if such a railway achieves what Ren Baqian said, it would be too valuable and worth the risk.

Besides, they don't need to pay much.

Whether it is a mine or a captive, it is all Izumo. The most important food and grass problem can be solved by the high-yield foods such as pumpkins and sweet potatoes brought by Ren Baqian.

What they have to do is to lay down Izumo, which is already planned.

Everyone has long coveted Izumo's riches.

Even if there is no such goal ~ lightnovelpub.net ~ everyone will not let go of this fat, let alone this fat is already on the chopping board.

Today, Dayao has sent 60,000 reinforcements to the Northeast Metropolis, and the original Northeast Metropolis has a total of 70,000 troops. It is close to the country ’s original military strength, and all have been invested in Izumo.

Izumo has now lost a quarter of the land, and the country is in a panic.

Everyone jumped off the train and watched the train run for six full hours beside them. As Ren Yaqian said, without any slowdown, they returned to the city to arrange the next thing.

The looting of iron ore and the laying of railroad tracks have become one of the most important things in the hearts of everyone.

And Zizhu Academy should continue to improve the train design to ensure that there are no problems. If you can double the speed like Ren Baqian said, everyone will wake up laughing.

Let them lay down Da Xia, they said nothing and immediately prepared for war.
