Daming: I, Yang Xian, really govern Yang!

Chapter 165: Exchange distance for power

"How about it, I'll just say it's easy." Yang Xian turned to look at Hu Ye and smiled.

"Master Yang, you are so strong, of course it is easy."

Hu Ye still didn't believe it. In her opinion, it would take several cows to pull the water directly up from the bottom of the mountain through a rope.

She looked up at Yang Xian, the expression on her face was like looking at a monster. No wonder he could carry a bucket full of water with one hand so easily. He didn't even spill a drop of water all the way up the mountain.

"If you don't believe it, try it yourself." Yang Xian said helplessly.

The little girl Hu Ye was doubtful, so she walked over and took the handle handed over by Yang Xian. She subconsciously tried her best to spin it in a circle, but found that the handle seemed to be greased. She turned it in a circle with a slight flick.

Is this so easy?

There was an expression of disbelief on her face, and she tried to spin a few more times.

I found that the handle in my hand turned extremely smoothly.

Moreover, every time Hu Ye turned the handle in his hand a small circle, the water wheel beside him would rotate accordingly. After about dozens of turns, the wooden frame filled with water under the cliff would be transferred to the mountain.

Is this simply a miracle? !

"How did this happen?!" Hu Ye still felt a little unreal until the water was transferred up, and he was stunned.

"It's all thanks to the pulley block." Yang Xian pointed to the distance and said with a smile.

Simple high school physics, the force of the moving pulley is halved, the stroke is doubled, and the force of the gear shifting stroke is increased to shorten it.The more pulleys there are, the longer the stroke. To put it simply, distance is exchanged for force when the work is constant.

So although it's a little troublesome and requires a few more turns, it's completely effortless.

Compared to going directly to the mountain to fetch water manually, the time wasted is nothing.

Besides, later on, you can just find a donkey and throw it here and let it keep spinning.

By then, the water source on the mountain will be inexhaustible. Not to mention the four and a half acres that Hu Ye and his daughter have now, even if it is ten times more, it can fully meet the needs of field irrigation.

After the most difficult link is solved, the rest is simple. Just use the water truck to direct the water delivered to the cultivated fields.

This is not complicated. The waterwheel technology in the Ming Dynasty was very mature, and it didn't take long for the construction team brought by Yang Xian to complete it.

Hu Ye and his daughter just watched the water pass through the wooden boxes one after another, following the inertia, and finally poured on the cultivated land not far away.

In their eyes, Yang Xian, who could do all this, was no different from a god.

Uncle Hu's face was full of excitement. He pulled his daughter Hu Ye, knelt down in front of Yang Xian, and said gratefully.

"Master Yang's great kindness to us will never be forgotten in our lives."

"Get up, no need to be polite." Yang Xian smiled, stretched out his hand to help them up, and then said. "I am also entrusted by others to be loyal. If you really want to thank me, then go and thank Li Jin."

Hu Ye and his daughter said that Li Jin wanted to thank him, and Yang Xian wanted to thank him even more.

After another thousand thanks.

Yang Xian took a look at the sky and it was almost time to leave.

Yang Xian stood by the cliff on the mountain and looked into the distance. On a straight track, a speeding train was heading towards Dingyuan ahead.And this track will lead all the way to Zhu Yuanzhang's hometown, Fengyang.

Yang Xian wants to spread the tracks to all parts of the country based on the current stalls in Yangzhou alone. Not to mention a series of follow-up issues such as manpower and management, financial resources alone are not enough to support it.

Even now Yang Xian's Yangzhou can be said to be extremely rich.

Infrastructure construction is always the most expensive.

Take the construction of highways in later generations as an example. Generally speaking, the cost of highways per kilometer is between 5000 million and 1 million, and the construction distance (bid section) of highways is generally within 100 kilometers, which means that you have to It takes 100 billion to complete the construction of the expressway.

From project establishment, approval, land acquisition, and construction, the whole process lasts at least three to five years. If it goes well, it will be opened to traffic in seven or eight years and then the money will be collected. If it does not go well, it will take 10 years. There are also the above.

In addition to construction costs, there are also maintenance costs.A rough estimate is that the annual maintenance cost of a 100-kilometer highway is about 8000 million, including road maintenance, mechanical and electrical maintenance, personnel salaries, etc.The cost of maintenance every five years and major maintenance every ten years is calculated separately.The cost of overhaul can even account for one-third of the road construction cost.

So, how much can we collect in annual tolls for these 100 kilometers?At 5 cents per kilometer, assuming that 5 vehicles pass by every day, and each vehicle pays 50 yuan, the annual fee earned is about 9 million.Excluding the annual maintenance fee of 8000 million, it will take about 13 years to pay back the capital.But don’t forget that highways are repaired every five years and once every ten years.In these 13 years, billions of costs will be incurred.

In other words, even if the highway tolls are already so high, the return on investment is still far away.

In some places, there will even be losses for consecutive years.

The construction cost of rail trains cannot be compared with that of expressways, nor can their ability to make money.

At this time, the court's support is needed.

It's just that now, the Ming Dynasty's treasury is really too poor.

Although Yang Xian has taken several shots of cardiotonic pills in succession, it will take some time for them to take effect.

Now we can only wait for time.

Yang Xian originally thought so, but that day Zhu Biao suddenly came over and asked Yang Xian's train bureau to open the track to Peiping as soon as possible.

In terms of funding expenses, the imperial court will fully bear it.

If such a good thing comes to his door, Yang Xian will naturally not miss it.As for where the money from the imperial court came from, he didn't go into detail for a while. He just assumed that it was the imperial court's income from the sale of colored glazes with the Western Regions during these days.

As for why, the imperial court was eager to build roads.

The purpose is of course to open up the logistics and transportation of the border defense in the North.

With the existence of rail trains, the northern border troops will no longer have to worry about anything.

"Is the situation in the north getting tense again?" Yang Xian asked.

You must know that it has only been two years since the last time they repulsed the prairie cavalry that invaded the border.

And through the wool trade in the past two years, it stands to reason that the lives of the people on the other side of the grassland should be getting better and better. At this point in time, there is no reason to provoke the Ming Dynasty.

Zhu Biao looked solemn, nodded, and said, "Yang Qing, your guess is correct. According to reports from spies at the border, there are signs of Wang Baobao mobilizing troops. We must prepare early."

Wang Baobao?
Yang Xian nodded. It seemed that although Beiyuan's side had declined, there were still people with brains.

I know that if things continue like this, in ten or twenty years, even if they want to resist, they may not be able to resist.
