After Zhu Linmiao's Yunnan policy was implemented, the Tusi would not only rely heavily on the food of the imperial court, but also the goods they produced would be purchased by the household family. If they commit any more misdeeds, the household department will only need to adjust the purchase price slightly to make them miserable, and as for the reduction of food supply, it will kill them.

Just when the toasts were excitedly discussing the good "money" Cheng, there were also discordant voices, and a tall and thin toast arched his hand and said: "Your Highness, the lower officials are not questioning the imperial court, but according to what His Highness said, every month, the household department will collect hundreds of thousands of catties of wood, iron, coal, etc. to ride horses, so many things and how to transport them?" The household department won't deal with me, and it won't be over in a month, right? ”

In fact, many of these toasts are quite business-minded, and they also know that if the "worthless" products at home are transported to Liangguang, no, they can be exchanged for a lot of silver just by transporting them to Kunming.

However, with the current transportation capacity of the Ming Dynasty, the cost of transporting these things to Kunming far exceeds the value of the items themselves. It is because they can only watch things rot in the mountains for generations.

As soon as the thin and tall Tusi spoke, many people around him immediately echoed, "The king's inspection is not bad. ”

"Yes, you have to be tens of thousands of strong people to transport so many things."

"The imperial court still has to transport grain to sell, and the cost of carriages and horses is even greater......"

Zhu Linmiao smiled slightly when he heard this, he had already made up his mind about transportation, otherwise he would not have proposed this strategy of "guiding the industrial structure of toast".

His solution is wooden rail transit.

In fact, as early as the 17th century, European miners began to try to build wooden rails in order to increase transportation capacity, but due to the lack of maturity of technology, it was not until the end of the 18th century that this mode of transportation began in England and spread widely throughout Europe.

Although the earliest wooden railcars were still dragged by horses or donkeys, their cargo volume was more than ten times higher than that of horse-drawn carriages on ordinary roads! It's also about twice as fast.

With the development of wood rail technology and the emergence of steam engines, the earliest steam trains were finally born.

Wood rail transit technology has been improved in Europe for more than 100 years before it matures, but for Zhu Linmiao, these technical improvements are just some small tricks, but people didn't think of them hundreds of years ago. Later generations of train tracks were much more complicated than that.

The most important technology of wood rail transportation is only a few points: the structural design of sleepers and tracks. This one is directly copied from the railroad tracks, and the material is replaced with wood. Later, it can also be added to the bread tin sheet outside the wooden rail.

Wheels with protruding edges. This is the easiest, as long as you draw a sketch, you can make it by a carpenter.

Brake system. In the early stage, wooden wheels and cowhide can be used, and when Daming's rubber is produced, it can also be replaced with rubber brakes.

Trigger system. Although this is a bit more troublesome, it can be ignored in the early stage. After the carriage is emptied, it can be carried directly on the track by manpower. After the construction of the wooden track network extends in all directions, it will be too late to slowly improve.

As for the carriage part, you can directly use the ready-made carriage carriage, which is still dragged by mules and horses.

The wooden rail technology looks very simple, but due to the greatly reduced resistance of the carriage and the ability to pass as usual in rain and snow, its capacity is thrown a few blocks away from the traditional carriage.

At the end of the eighteenth century, it was precisely because of the popularity of wooden tracks that the transportation cost of British mines plummeted dozens of times, but the transportation capacity increased more than ten times! It provided a steady stream of cheap raw materials for the British Industrial Revolution.

In fact, Zhu Linmiao has long wanted to engage in wood rail transportation, if Daming can popularize wooden rail, the transportation cost of various materials will drop significantly, and it will also play a great role in promoting the commercial development of the whole country.

In particular, the price of wood, ore, and coal will even be reduced by half, which means that the cost of producing guns and shipbuilding can be reduced by three or four percent in the future.

In addition, strong transportation capabilities are also of great military importance.

The first is the movement of troops, with tens of thousands of troops using rails to transport them, even faster than cavalry, but only a few thousand horses.

The second is that it will greatly improve the logistics supply capacity. In the wars of the 17th century, the transportation of grain and grass had a decisive impact on the situation of the war. Although Jianyu had a total of hundreds of thousands of Manchu and Han troops, they were at most able able to invade the south once every six months, and the reason for this was that they were dragged down by their logistical supply capabilities. If you want to transfer grain from Beijing and Shandong to the Jiangnan battlefield, the process of raising and transporting it will take at least three or four months.

Previously, Zhu Linmiao was fighting in places controlled by the Ming Dynasty, and the logistics were basically not a problem, but he knew that when the Ming army crossed the river and went on an expedition to the north, the battlefield was in the enemy-occupied area, and the logistical pressure would become very great.

Taking into account all aspects, it is advisable to start the wooden rail transit as soon as possible. This time, there is an opportunity to control the toast, so it is just right to carry out a pilot project in Yunnan first.

The construction cost of the wooden track is extremely high, and Zhu Linmiao roughly calculated that it usually takes nearly 700 taels of silver to lay a mile. However, there is a large number of cheap labor in Yunnan, and the timber is more or less, and the cost can be reduced by about 40%, which is very suitable for the pilot of the wooden track.

But even so, Zhu Linmiao's money is not enough to build a dense rail network in Yunnan. At the beginning of his planning, he only laid three lines: northern Yunnan, western Yunnan to Kunming, and from Kunming to Tianzhou.

After the materials are transported to Guangxi, they can be transported to Macao by river and land, and then sent to all parts of the country by sea from here. Even so, the completion of this wooden rail transit line will probably cost nearly one million taels.

He glanced at the questioning toast, and said loudly: "You don't have to worry about the problem of transportation, the imperial court has planned to build a wooden rail line in Yunnan, and hundreds of thousands of catties of goods are not a problem."

"As for the purchase of your property by the household department at a high price, this is the national policy of the imperial court to appease the Yunnan region, and it will not be changed overnight. After a long time, everyone will naturally know. ”

According to Zhu Linmiao's plan for a rich country in maritime trade, a large number of warships, merchant ships, and cannons will be manufactured in the future, and this little material in Yunnan may only be enough for four or five shipyards to consume, and it will produce as much as it wants.

As for the import of grain into Yunnan, it is not a problem, Jiangxi potatoes and sweet potatoes have been spread out and planted, and many people in Fujing and Guangdong have also tried it, and soon Guangxi and Yunnan will also start to promote it. It is foreseeable that this year's autumn grain harvest will be at least three or four percent higher than usual.

It is definitely not a problem for the surplus grain to feed these toasts, not to mention that they themselves are still producing grain for the time being, and when their own land is no longer grown, the Ming Dynasty has planted potatoes and sweet potatoes everywhere, and the grain has long been no problem.

With the personal assurance of His Royal Highness the Auxiliary King, the Tusi settled down. In fact, Zhu Linmiao didn't expect them to come according to their own intentions immediately, and when they saw the silver in the future, they would naturally try their best to produce what the court needed, and gradually no one would have the intention of farming anymore.
