The seventy-sixth year of the Great Yao, August.

After the retreat of the day, everyone did not leave, but waited in front of the palace, a slip of rare mounts were moved by the guards, white toothed tigers, five or six meters tall orangutans, huge cats with horns on their heads and pure black bodies, and huge lizards like western dragons......

The red horned king, which is larger than the average horned cow, is not visible at all.

It's about the equivalent of an Audi A4 squeezed into a row of sports cars.

There is also a high-equipped Wuling Hongguang next to him - a black Langjun with the strength of a ground ring, his back is more than three meters high from the ground, two fangs poke out from his mouth, and he restlessly used his hooves to dig out two holes in the stone slab on the ground.

The guards not far away wrote it down in a small notebook and turned around to fine.

If it is somewhere else, if the front of the palace is destroyed, maybe the whole family will be reunited.

However, for Da Yao, the palace door has been accidentally injured and I don't know how many times.

The stone slabs in the Jinluan Hall have to be replaced every few days.

Everyone stood outside the palace and waited, chatting in groups, and from time to time they could hear someone asking what they were going to see this time.

After all, His Majesty left everyone behind with such fanfare, which makes people curious.

The last time I was in this situation, I watched something called a steam train.

I have to say that the steam train is really magical, you only need to fill it with some burning stones to keep running, you don't feel tired at all, and the strength is not small.

When everyone was chatting and discussing, the main gate of the palace was opened, and the empress's luan drove slowly out of it, and after a slight pause, she set off for the east gate.

Along the way, many people first cheered, and then followed all the way out of the city gate.

By the time the empress and others left the city, there were already nearly a thousand people behind them.

At this time, on the cement pavement outside the east gate, there was an object several meters long, wrapped in red cloth, and Ren Baqian sat on the side and looked up at the sky, followed by many students, and got up to meet everyone when he saw everyone coming.

"Prince Zhao, is there anything good for us to see this time?" Tong Zhenye stroked his beard and laughed.

Everyone has long understood that as long as there is something to show them, don't think about it, it must be made by Prince Zhao.

For what he made, everyone was still quite excited.

Every time, it will amaze everyone.

"You'll find out soon. Ren Baqian smiled at everyone, and looked up at the civilians who were following in the distance, this was a good promotion opportunity.

With today's performance, the new thing such as the tractor will inevitably spread in Lancheng, and when it is actually launched after a period of time, the people of Lancheng who have been waiting for a long time will be able to see the real face, and there must be people who are willing to try.

The only question is whether anyone can afford it.

Even if he is ready to sell it at a loss, the purpose is to promote this new thing, improve Dayao's transportation capacity, and reduce the use of manpower in many aspects, so as to improve the current shortage of manpower.

However, it takes time to promote, even if it is a loss of money, the price is a big problem.

At present, the largest customers are still the Ministry of Industry and the Ministry of War.

However, in Ren Yachi's view, the greatest value of the tractor is not only transportation, if you only talk about the transportation from Arashiki to Izumo, it is still the truck that is faster and has a lower technical content than the tractor.

In addition to being able to be used on various dirt roads in the south, tractors are also important to replace manpower, freeing up a group of laborers from the fields and putting them into factories or other places.

Ren Baqian wanted to reach out to support the empress, but the empress disappeared from Luan Jia in a flash, fell to the ground, and just behind Ren Baqian, she didn't look back and said, "Let's go, take a look at your new products." ”

Ren Baqian smiled helplessly, even if she was thirty-two months pregnant, the empress was still the empress, and she was not pretentious at all.

"Ladies and gentlemen, this is an epoch-making product. Ren Baqian said in a loud voice as he walked forward.

"That's what you said last time!" Qin Chuan said not far away.

"Epoch-making technology is coming too fast!" Ren laughed. "Or that this era will change very quickly!"

Walking to the tractor, Ren Baqian pressed his hand on the red cloth and turned to the crowd: "The last steam train, you can see its potential, with the steam train, you can connect the two distant places in one place, and within three days, you can transport 100,000 troops and matching materials to Izumo, and even Great Xia, which has completely changed the previous concept of war before the soldiers and horses are moved."

In the face of war, we are able to have faster reaction speeds and better mobility. ”

"The question is, where is the war coming from, and who is fighting?" Qin Chuan spread his hands, and if he fought again, there would only be Daxia and Izumo, but at present, he couldn't even eat Izumo, and Daxia was too busy to take care of himself, and it was foreseeable that there would be no war in ten or twenty years.

"War is just one example, more important is transportation. With Izumo, the price of iron in Arashiki is now only one-fifth of what it used to be, and the transportation of large quantities of supplies is still a problem. With trains, transportation will be easier, faster, and consume less manpower and material resources, which will naturally be worth it in the long run. Especially in the transportation of fresh materials, this is incomparable to land transportation. Ren Baqian said casually.

"If it weren't for those big iron eaters, the price of iron in Lancheng would have dropped to half of 10% now. Someone next to him whispered.

Ren Baqian looked at the past with horizontal eyes: "In the long run, just one iron, not all, grain, vegetables, fruits, cloth, minerals, do you still want to bring back Izumo's iron production in ox carts every year?"

The crowd burst into laughter.

It was an official from the household department who interjected, full of resentment.

In fact, not only him, but the entire household is not small.

Those steel mills and rails are like iron-swallowing monsters, like bottomless pits. In the past two years, at least more than half of the iron ore mined in Izumo has been invested, and there is not even a splash in it.

You must know that one meter of steel rail costs 100 catties, and the rail needs to be double-sided.

One kilometer is 200,000 catties.

It is equivalent to the annual iron ore production of Dayao before.

This number was calculated, which made everyone in the Ministry of Industry and the Ministry of Households feel a little dizzy.

Originally, Izumo produced about 22 million catties of iron a year, and less than 3 million catties of steel. In the past three years, with the large-scale use of steam engines in various mines, the iron output has increased to 40 million catties, and the steel output has approached 10 million catties.

Most of the steel production is put into rails.

In the past two years, only 100 kilometers have been laid, which is equivalent to 200 miles.

At the current rate of steel production, it will take at least 10 years to complete the railway.

However, this output is only now, and in Ren 80000's estimate, the iron output can reach 80 million catties and the steel output can reach 30 million catties within five years.

It seems like a lot, and if you calculate it carefully, it is only 40,000 tons and 15,000 tons respectively.

Not to mention compared with the Republic of China period, even compared with the Song Dynasty, it is far behind.

The biggest limitation is not only technology, but also the equipment and technology used today in mines and steel mills that are at least at the level of the middle of the Industrial Revolution.

However, the number of supporting technologies and personnel cannot keep up.

For example, equipment manufacturing, equipment maintenance, personnel training, and so on have formed shackles.

It will take at least three years for these conditions to ease, and five years before they erupt.

But the investment in steel alone is an astronomical amount, not to mention the manpower and material resources invested.

Even if the situation of the state treasury has improved greatly in the past two years, the annual investment is enough to make everyone in the household department feel painful.

This is true even if you know the significance of the railway.

Therefore, the people of the household department have resentment, and everyone does not think it is strange at all.

Whoever you change is distressed!

Not to mention the household department that has always been picky.
