Most of the merchants need money or goods that can be exchanged for money, although they also need food, but the quantity is relatively small, because most of the things they sell are luxury goods. If they exchange it for food, they can't transport it back, so they can only exchange it for money or other items like silk.

Now Fan's Manor offers them a new choice.

"Why do you think about these rich people? What I should think about is to make the poor rich, and let the poor have something to eat, and the rich people have food in their warehouses, and the food is about to go bad, and there is no way to sell it, the main reason is because these poor people can't afford to eat.

However, if the poor can afford to eat, they will not farm for these big landlords, and the big landlords will not have enough food, which is also a very big problem.

The big landlords of later generations were still able to grow enough food, because they did not use much manpower, and the output of grain increased many times.

The goal is just to let them have a house to live in and something to eat, and it was very difficult to live in a house in the era of Kezhi. ”

Fan Jingjing knows that among the people of Chang'an, she is a successful person, but she just wants to feed thousands of people, which is actually very difficult for Datang, and it is unimaginable in many people's imagination.

Unless thousands of people in the Fan family manor are made their slaves, there is no problem with the slaves to eat well, but Fan Jingjing lets them work for themselves, and they are not only full, but also very rich.

How thick the track should be has something to do with the negative gravity above, Fan Jingjing is not ready to make a slow train all at once, Datang is still the era of manpower, and it has not yet reached the era of mechanization, she thinks that the trolley is still one of the important means of transportation in the mountains.

The rail cart can also push very heavy things, the important thing is that it is monomeric, so the overall negative gravity is not strong, and for the laying of the foundation, the requirements will not be many.

And the first to occupy the land, can help the later upgrading, if the train is really invented in the end, you can also change the track laid at the beginning into a special track for trains, without the need to levy roads, of course, Fan Jingjing knows that the later development will leave more space on both sides of the track.

At the very least, there is no way to build some old buildings on both sides of the track that must be preserved.

It needs to be preserved, and it is roughly a celebrity building.

People who will become celebrities should be more faceless, Fan Jingjing believes that they should not build their own houses in places with obvious violations, there are not many settlements now, there are not many houses that need to be demolished to lay tracks, and laying tracks is equivalent to occupying the territory, even if you need to pay some money, compared with the application of tracks, it is much worse, not to mention that if it is open to ordinary people, the imperial court should not be able to collect these money.

However, if the magistrate wants to make money, he will see the needle, and in order to prevent problems in the future, it is better to occupy the land with the consent of the local government.

Just like the emperor doesn't want to care about these things, there is still the queen who can take care of it, and when it comes to the interests of the Tang Dynasty, he will generally approve it.

As long as it doesn't involve national affairs and court affairs, the queen still has some rights.

What's more, these things are beneficial to the imperial court, even if they will be expropriated by the imperial court in the end, as long as the imperial court can make good use of this land and continue to develop the railway, even if in the end, it doesn't matter if all these properties are contributed to the country.

She believes that her children and grandchildren may not only produce good people for generations, and there will definitely be losers.

In order to maintain development, in fact, there must be many patriots who continue to develop for the country with patriotism.

In fact, Fan Jingjing knows that the easiest way to increase food.

It's like the ocean taking.

The current numbers, and the technology, can't make the ocean extinct.

In the future, if there is a crisis of extinction in the ocean, it should be considered by the current generation, because the crisis must be the result of ocean exploitation, and the result of marine exploitation may be due to too many human beings, which will cause the crisis of biological extinction.

Tell the present people early that they can only be used as a joke, because they do not live in a hypothetical environment, and they do not have a sense of crisis.

Unless a disaster has ever happened.

But before the Tang Dynasty, people only felt that the population was too underpopulated, but they did not feel the crisis of overpopulation.

The crisis of overpopulation will probably not be felt until after the Ming Dynasty, because after the Ming Dynasty, people have given birth to too much, there is no way to solve the food problem, and new food has not yet been transmitted to the Ming Dynasty.

In fact, in the Ming Dynasty, if there was no grain coming in one after another, there was no way for the population to increase later.

Many people will starve to death, only some of the rich people will be able to live a good life, and the number of rich people will remain at a fixed number, because in particular, when more assets are collected, the number of people will slowly decrease, because when they get too much, there will be more waste, and the rest will not be given to some poor people to eat, they will feel that since they earned it, why should they give it to others?

This is not to say that they are wrong, but if they don't give the excess to some people who are too poor to live, and let these people protect them, it is likely that there will be more people who can't eat, and they will fall in love with him, and find that he has no one to protect, so they bite their teeth, and in the end they feel that it is not difficult to shake easily, so more people gather and bite.

In the end, the rich man has no way to maintain his wealth. No matter how many people there are, the sperm whale can only die in the end.

If you want to know about the orbit, you can only find Jiang Blacksmith, because this matter is all handed over to him, and he is required to keep it a secret.

Even if you want to use rails, it is not something that ordinary iron can do, and you have to find a way to reduce the cost and let the trolley pass smoothly, so the surface of the iron is very smooth and there can be no bubbles.

It is very difficult to do it for the era when Datang pays attention to handiwork, so Fan Jingjing also talked to him about the problem of the lathe, the quality of the iron with the lathe will slowly improve, of course, there are many tools, but Fan Jingjing can't remember anything else, he can only think back a little when he sees it, and make some points, whether the points are effective or not, only Jiang Blacksmith can understand, Fan Jingjing can't figure it out.

"We have built the rails, and in the tests we have carried them every day with a car carrying ten stones, and then we have tested the wear and tear of the rails.

You've said that there's no way to really achieve it until the results are shown, and the biggest problem is actually rust.

As I said, rust is not too much of a problem, and if the car rubs back and forth on it every day, there is no chance to upgrade it.

But there may be a risk of rust at the bottom, because only the upper half is rubbed. ”

Fan Jingjing's brows furrowed, this problem is a big problem, once rust occurs elsewhere, it may collapse, there is no way to carry so much weight, and if it is not inspected in detail, such a loss may make the car unable to push halfway, and it must be repaired at any time.

"He also told us that there are some alloys that can make iron that doesn't rust, and we've been working on this part as well, and it might take a while.

It would be nice if you could provide some examples......"

"How do I provide an example?"

"The suitcase you brought at the beginning should be a product of Shuiyun Palace, and it should not be rusty, right?"

"You said the trunk?" Fan Jingjing was surprised, Jiang Blacksmith still remembered her suitcase, she hadn't rummaged through the suitcase for a long time, the contents of the suitcase had already been taken out and put in the wardrobe, and those clothes were not suitable for wearing in this place, so they were all put in the cabinet and did not move.

As for the seeds in the suitcase, they had already been scattered by her in the fields, or in the barren mountains and mountains, and with the help of condensate, they had also matured and grown, and there were hardly any seeds that did not sprout, unless there was something wrong with the seed in the first place.

Where Fan Jingjing bought seeds, it seems that she is still relatively honest, if she has the opportunity to return to the era of science and technology, she must help him give him a big thumbs up.

"Okay, I'll hand over the iron products on my body to you, and I hope you can research qualified steel as soon as possible."

"Actually, your initial plan should be achieved, now we have experimented for fifteen days, and it is a non-stop day and night to transport hundreds of pounds of things back and forth, and another fifteen days of experimentation, to make sure that there are no dents, basically it's okay.

However, I think that if the problem of rust is not solved, it is actually very unsafe, because iron products can be easily stolen if they are placed on the ground, and they must be replaced from time to time, after all, these things cannot be exposed to the sun and rain. However, the cost of iron is very expensive. ”

"Don't you know that iron can still be recycled and re-refined?"

"We know that rusty iron has a lot of impurities, and if you make it again, you won't be able to make good things."

"Not all iron tools have to be very tough and durable, different things need different iron tools, if you are a little more skilled, you can make tungsten steel, maybe we can invent the light bulb."

Fan's Manor is electrified, but these stores must constantly generate electricity, once it rains heavily, there will be problems with power transmission, and there will be power outages, so there are still candles or other things that can be lit in Fan's Manor, but in normal times, people will use the power to make some products when the electricity is sufficient during the day, because electricity has slowly begun to make electricity products to increase the benefits of life since the emergence of electricity.

And many of these people are princes and princesses, because they were the first to learn Fan Jingjing's physics, especially Li Chengqian and Li Lizhen, and now studying things is equivalent to studying crazy.

Every thing they produce, if it can be manufactured in large quantities, it can be sold very well, so that they can make a lot of money, although they are princes and princesses, it does not mean that they have the freedom of money, the money they earn, Fan Jingjing's Fan family manor will not hack them, it is clear that the money will be sent to them, after they use the money to do a lot of things they want to do, although they find that if they can invest in production, they will be able to make more money.

In many cases, they do not sell their intellectual property rights to Fan Jingjing, but put them into production themselves.

This is also what Fan Jingjing is happy to see, the reason why she acquired intellectual property rights is just to let people know that intellectual property rights are valuable, and if they are produced well, they will be more valuable, but when the prince and princess began to snatch intellectual property rights with her, she had a little headache.

Fortunately, now they are looking at things that make money, and things that make money sometimes seem to be very superb on the surface, but in fact they are not necessarily very wide at the application level.

There are always many things in the world that are beyond her imagination and beyond her control, if Fan Jingjing is in the era of science and technology, she will not want to control other people's lives at all, she just wants to live her own life and let others not bother her.

Fan Jingjing introspected deeply, and after coming to Datang, her desire to control seemed to have improved a lot.

"Actually, after a while, we will be able to research some new recipes, and the updated recipes will have to be re-experimented, and let the rails go into the mountains, which is the best way to develop them.

It is indeed the easiest way to transport it by cart, especially for those who do not want to walk on their own. ”

Blacksmith Jiang knew Fan Jingjing's plan for the amusement area, and the first places to use these railways in the later stage would be these amusement areas, and they would not be spread out outside until they were mature.

The biggest reason is that iron is a very expensive material in Datang, and sometimes it is even used as money.

So if these things are put outside, then people will come to steal, so they can only be used on their own territory, and the tourist area is currently more crowded, and the opening of the railway can attract more curious people to know.

However, if the problem of theft is not solved, the traffic can not really be promoted, and only cement roads can be used, after all, no one should steal cement roads, so it is useless to steal.

Fan Jingjing suddenly thought that there seem to be a lot of caves on the Loess Plateau in the north, the caves are warm in winter and cool in summer, and they are the most suitable for summer living, but unfortunately there are no related materials in the Guanzhong area, and the loess is not available everywhere.

Fan Jingjing wants to find a loess cave to live in, because she really can't stand the summer steaming, although the environment of the Fan family manor is already very good, but the whole summer is still very hot, if there is a cave to live in, the life of confinement is estimated to be not so difficult.

But if she wants to leave the Fan family manor, she has to endure the toss of the road, and she can't bear it, she wants to lay a section of railroad track to the Loess Plain.
