When Sun Xiangfu came to the car yard, he was immediately amused by this rather joyful thing in front of him, which was a walk-behind tractor!

"The front of the car doesn't look big, is the horsepower enough?" Sun Xiangfu looked at the front of the car, which had been wrapped in an iron shell.

Sun Xiangfu said that it is not big, in fact, it is much larger than the front of the walk-behind tractor in later generations, and even slightly larger than the front of the Shenniu 290. It's just that it is smaller than the size of the steam engine that Sun Xiangfu imagined, which can drive thousands of catties of goods.

"It's big! We loaded 5,000 pounds of goods on the carriage, and we were still able to maintain a speed and drive easily, and we could even climb a slope of more than 30 degrees. Yu Jie explained with some pride.

Since Marseille went to specialize in electric power research, Yu Jie has become the chief engineer of car manufacturing research, this is the third trial of steam-powered vehicles, and all aspects, in the eyes of these technical research and development personnel, have become perfect.

"Really? How many gears are there in the power design? Sun Xiangfu said, he had already sat directly in the driver's seat, and Li Chengqian, Li Tai, and Li Ke, who had already seen two tests before, were watching some changes in the front of the car.

"Four gears, the first gear can reach five miles per hour, the second gear is doubled, ten miles, the third gear is doubled, twenty miles, the fourth gear, and then doubled, forty miles. The load is five or six thousand catties, which basically does not affect the speed.

What's more, we've added a reversing gear, which allows you to control the speed of reversing with the handbrake. Yu Jie pointed to the front of the car and introduced Sun Xiangfu.

"Really?" Sun Xiangfu said with some surprise.

Reversing gear, but they did not solve the problem in the first two tests, this time, it was also solved, although the speed of 20 kilometers per hour, there is a bit of slag, and the speed of any tractor in later generations can reach 40 kilometers per hour, but considering that it is a steam-powered tractor, this is actually quite good, can have such a speed, or because of the fuel it uses, is the reason for refining high purity gasoline, however, after several generations of improvement, it still has a lot of room for improvement.

In one day, five or six thousand catties of goods can be transported to a place eight or nine hundred miles away, which has crushed all existing land transportation, not only the speed is more than twice as fast, but the transportation cost has also been reduced several times.

Because of the carriage to pull such a heavy cargo, at least two horses pull together, a day down, at least six to eight times to change horses, this is a dozen, and can only walk two or three hundred miles a day, once the time is stretched two or three times, the whole person eats horse chewing and labor costs, will increase several times, the price difference, so it arises.

Of course, this load, and the later generations of internal combustion engine walk-behind tractors are still huge, the later generations of twelve-speed walk-behind tractors, even if the load is five or six tons, can run faster than it, strong power, is the characteristics of the tractor.

"Get started, children, get in the car, Daddy will take you around Weinan City." Sun Xiangfu smiled and saw clearly the designs of the gear and handbrake and foot brake, and he was very familiar with grabbing the two handles of the tractor.

"This, you haven't learned how to drive, can you drive it well?" Yu Jie said with some concern.

"Remove the word 'what', such a simple thing, can it still be difficult for me?" Sun Xiangfu smiled.

At this time, on the tow box of the car, Sun Jing and Sun Wanting, the two big ones, had already taken the lead and climbed up, and then reached out to bring Sun Feng and Sun Wanyu to the top of the tow box.

Sun Xiangfu liked their kind of unity and tacit understanding that they did not need to explain, and after Li Chengqian, Li Tai, Li Ke, Cheng Chumo Yujie and others sat down along the door panels on both sides of the trailer, the car finally moved.

"Babble, Boom, ······Boom, Sun Xiangfu grabbed the gear bracket in the center of the handrail, hit the first gear first, and the car was very fast, and he left the factory building and ran out of the road.

"Oh, run, run······"

In the trailer box, the children cheered proudly, Sun Xiangfu had a lot of dealings with this kind of agricultural machinery and equipment in later generations, driving a tractor, a cultivator, a threshing machine, it was easy, which is why he was able to make a lot of suggestions when Yu Jie developed this car.

"Sit tight, I'm going to speed up!"

Sun Xiangfu dialed the gear again, and soon, the car shook and entered a faster speed mode, which is the steam engine, which is not as easy to control as the internal combustion engine, and the speed is doubled every time the gear is raised, a little too fierce, he thinks it should be divided into six to eight gears, and gradually increase from low speed to full speed.

Of course, this kind of low-gear conversion, there will not be too much bumps, and when the last third gear is changed to four gears, everyone feels that it almost has the speed of a galloping horse, and you can slightly feel a little whirring wind in your ears.

The speed is 20 kilometers per hour, and if you drive back to Chang'an from Weinan, it will take two or three hours! Sun Xiangfu naturally will not suffer from that sin, in the chatter of the children, Sun Xiangfu is also talking to Yu Jie, and Li Chengqian about some of the disadvantages of this tractor, so that the final production version can be more perfect.

After a while, the car was on the main road in the city, and although most people would stop to watch the guy running forward, there was no look of disbelief in surprise, because, before, the car had already been tried twice.

Compared with the steamships that can be seen often at the Weinan wharf, it is not too unusual, and the factories have now begun to put on the operation, or are preparing to put on some steam equipment, some of which are even more magical than this tractor.

For example, in textile factories, there are steam-driven looms, which are constantly reciprocating, and can top the weaving volume of dozens of female workers every day, and they are still constantly experimenting and improving.

Almost all industries have made great progress in the development of more than ten years, which is why the income growth and prices of the people of Datang have only risen slightly.

In the process of the progress of the industry, the output of various industries is constantly improving, the cost is decreasing, even if the price of goods does not rise much, the profit space of enterprises has been steadily improving, which is why Datang and the countries of the Western Regions are now in such an unequal situation.

Why do they owe Datang so much money?

It is caused by complete asymmetry in the industry.

After Datang transformed all the inflationary pressures into these Western Regions countries, it was actually Datang's industry and commerce that defeated them.

When those kingdoms feel angry in the face of their own output, do you expect them to calmly confront you?

For example, a businessman in his country spends 20 yuan to support a skilled weaver who can help them weave 100 pieces of cloth a year, and they can directly spend 20 yuan to find a weaving factory in Datang, and they can buy 100 pieces of cloth with better quality.

You know, it is also a matter of spending 20 yuan to get 100 pieces of cloth, regardless of the quality gap, this businessman also has to invest in the production of cloth raw materials, but there are a lot, and the savings may be double the price, and countless times the time cost.

What can the rulers do when they put the things produced in their country on the market, and the price and quality are completely incomparable to the Datang production? The price is reduced, and it must be more than doubled, or even tripled, in order to be barely competitive.

But when the price drops by one or two times, they will find that the money they sell is actually a loss, and it can't meet the living needs of their own people at all.

If you don't recover the money from this outflow somewhere else, then after a long time, the problem will naturally come.

Although potatoes, sweet potatoes, corn and other crops were introduced from Datang, the yield they could grow was not as high as that of Datang, and although the food and crisis were not so serious, people lived, not just to barely survive, they would want to be better.

Among them, those who have money and the ability to learn will choose to go to Datang in order to change their lives, so their productivity will soon enter a vicious circle and become lower and lower.

Are there any self-sufficient countries?

Of course.

However, can these countries resist the temptation of Datang?

No way.

The principle of moving from thrift to luxury, and from luxury to frugality, is common in any race.

Even the princes of the Byzantine Empire can't resist the temptation of all kinds of commodities produced in the Tang Dynasty, and who else can resist them?

When you encounter an opponent like Datang, you can't compare to him in industry and commerce, and you will basically be defeated, which is nothing more than a few old empires that last longer.

The continuous loss of wealth will make a country's economy more and more tense until it collapses, people in this era do not know what economic regulation or trade restrictions, trade protection and the like, Persia, just think that they are on the thigh of the Tang Dynasty, and do not control their own flowers, and the first to mortgage the royal city and the palace to the empire of the Tang Dynasty.

Even in later generations, it is difficult for many people, or enterprises, to be freed from the road of borrowing, not to mention the people in this period when financial knowledge is in a blank state at all.

And the economic volume has reached the current level of Datang, playing with capital, you can easily play any country in the world, of course, playing military can easily play any country, but the reason why military restraint is maintained is because the problem of religious beliefs of the people in various countries is difficult to solve.

Among the surviving regimes in the world, only the Tang Dynasty was not politically swayed by religion and firmly established the path of scientific development, and the rest of the empires had their own beliefs.

For more than ten years, not all people in Weinan New Town have forgotten Sun Xiangfu's appearance, although he has a beard, his painting style has indeed changed, but after he drove a tractor around the main road in the city, the whole city exploded.

The managers and directors of each factory, in the escort of the tractor, got the purpose of Sun Xiangfu's visit to Weinan this time, and opened their doors one after another, and stood at the door of the factory with a senior management, looking at him with eager eyes, hoping that he could enter his own factory to inspect and guide, and perhaps, under his words, this industry will make earth-shaking progress again.

Shannan Road, Lingnan Road, Yunnan Road, Luosome Road, Dingxiang Road······

All right! Most of the people in the state of the country, when they saw Sun Xiangfu, they actually had a similar attitude to them, and even many people secretly set up a shrine for him at home to burn incense and worship.

At this time, in the divination pavilion of the eunuch of Chang'an City, Li Chunfeng, who was looking south, touched his beard with great satisfaction, and said, "The poor road has never been missed, Sun Zhengming's holy light has been revealed, and the sanctification of the Tao is not far away." ”
