For the people of the grassland, they must maintain their fighting form and maintain their safety at any time, so they cannot have too much burden on their bodies.

Since the main theme has been decided, it is relatively necessary to explore the opportunities and dangers of the north-west.

With such careful thinking and exploration, coupled with the advice provided to them by Fan Jingjing, they can roughly find out the direction.

In the books, they learned that the northwest was not really very poor, because the northwest had many products they needed, and even if they wanted to buy them, they had to spend a very expensive price to buy them, but if they started to transport materials from the northwest in large quantities, the price would naturally not be able to maintain a high price, and the price would soon collapse.

But the crash doesn't mean that these essential items can't be sold, and when the price drops, people start using them, such as leather clothes that they don't normally have access to.

Even people can start a lot of design, and other industries will be created.

After staying in the Fan family manor for a long time, they no longer have the same closed ideas as before, all the business, all the development in their minds quickly passed over.

Now they know that the reason why no one continues to develop many things is because there are not too many idle people, and if many people are not engaged in agriculture, it will cause a large amount of food shortage, so the local government attaches great importance to grain production.

If there is a shortage of food, the local government will even start to arrest people from the neighborhood and let some people start farming.

Of course, the introduction of meat in the northwest can make up for part of the food demand.

There is no way for people to continue working in the workshop, because without food, even if you work in the workshop, you will not be able to earn enough money to buy food.

Although the price of food is usually low, it determines whether people can do jobs other than food.

Agriculture was fundamental, and no dynasty had ever been able to take it lightly.

The development of business activities in the northwest is a big project, and it can not be done in a day or two, and the three of them can probably understand why Fan Jingjing wants to develop in the northwest, and develop in the northwest, Fan Jingjing can win more freedom, and she can sneak out when she arrives in the northwest in the future, not to mention that her industry is between the northwest and the imperial court, and she can also have one more reason to report.

The imperial court will not let the nobles have no way to manage their own property, and in addition to letting some stewards manage their own property, their own supervision is also very important.

However, this project is really a big project, if this business is easy to do, others have already done it, but when Fan Jingjing has thought about more than half of the things, then the difficulty of development in the future has actually been reduced a lot.

It's just that there are a lot of people who have to be deployed.

Some things that can't be done have to find another way, if all can be done, in fact, the development of the entire business route, no one can even compete with them, because every time you can't do it, in fact, it is a slowdown in speed and an increase in cost, which is actually bad for their business development, but although there are disadvantages.

If they can turn the northern barbarian land into their production base, as well as a livestock base, then they can produce a large number of meat products and transport them quickly.

But these meats can also be produced in Datang.

According to Fan Jingjing's guess, calculated from the local water speed, this place is probably transported down, and it doesn't even take four days, although the distance is very far, if you use the road to walk, in addition to facing a lot of dangers, more importantly, it takes a month for horses to walk on the road, but from the transportation of water transportation, it can be said to take a straight line, and it is the most gentle route, and it can also be transported in large quantities, it can be said that it can do what rail transit can do. However, if rail transit uses iron, there will be a lot of theft problems, and it will also cause a lot of dangerous problems, so we must find a way to solve this problem, or replace it with other worthless metals or non-metals, because iron can be smooth and wear-resistant, and there is a way to become smooth with other things.

For example, using jade or other gemstones, but the same jade or other gemstones will also cause the problem of theft, not to mention that jade and gemstones are not so pressure-resistant, which will cause greater losses.

Therefore, the whole cost will increase a lot, it is better to use iron, but the value of iron is a very important value in the grassland people or the Tang Dynasty, and there are blacksmiths everywhere, although they will not use the blast furnace to make iron, but they can burn the blast furnace, and then practice from the items they need.

In many places, even the government may support the local production of ironware, and theft occurs, after all, stealing from the scene and transporting goods to the city is a commercial act for them, and it is not beneficial for them, but if the transport of guests, only some people, can enjoy this right.

In any case, this has nothing to do with the average poor, the poor can make money by stealing iron, even if you can catch one or two, you can't catch a group of people, you have to patrol at any time, but there must be no way to supervise anyone on patrol at any time, so although the transportation system has an idea, there is no way to build it.

It is useless to wrap the ironware, because the ironware has to go through continuous wear and tear, and this friction must be consumed by the iron, although they do not understand the principle of this aspect, but since Fan Jingjing said so, they believe so, so in terms of long-distance transportation, in addition to the river, there is a very big problem in land transportation, even if the amount of bicycle transportation is not as good as the rail transportation designed by Fan Jingjing.

And rail transportation, because there is a fixed route, and even the route design is relatively gentle, so although the project is very large, but after it will be really opened to traffic, it will really become very fast in their imagination, not to mention that in Fan Jingjing's ideals, these cars are developed with electricity, and the development of electricity is maintained at a fixed speed.

Under the situation of Fan Jingjing's demonstration, they can see that these can almost be said to save a lot of manpower and material resources, that is, they will save a lot of transportation time and costs.

The more I studied the content summary given by Fan Jingjing, I found that there were many things that could be thought about deeply.

In the past, when they were doing business, they didn't think so comprehensively at all, but when Fan Jingjing was thinking, it was much more comprehensive than them, whether it was transportation, or live food, supplements were placed in it.
