Li Shimin is able to accept new things, but he ignored the development of Youzhou in the past, and in the future, Zhou Zhou not only has a prosperous business, but also treats craftsmen as the highest in the world.

Steam power is a concept, and they see it as nothing more than a device that provides heating.

The winter heating application in the palace of Wagang City is similar to that of a steam boiler, but it is obviously different from steam power.

The crawler transportation used in mining is steam power to drive the crawler to run, and when the eldest grandson Wuji asked people to take the equipment back, he organized many craftsmen to start researching.

Li Shimin also took a look at the past two days in three days, and he was very interested in the railroad cars that could move, and the thought of being able to develop vehicles that could move between cities was like getting results as soon as possible.

The principle of steam power is not responsible, as long as you have seen it, you can understand what it is, and it is difficult to understand that it is difficult to apply.

"Mowgli, how is the steam engine being studied, can it be imitated?"

"Your Highness, I have asked all the generals in Wagang if they want to build a simple boiler, but nothing else can be done."

Technical support is also required to prevent it, and steam boilers are not so easy.

Li Shimin's face is obviously not very good-looking, and being able to understand but not being able to make it is equivalent to looking at it.

There is no way to prevent the equipment from being disassembled into parts, because most of the parts are turned on steam-powered lathes and are not forged by hand.

"And the iron used in the steam engine is different from the ordinary iron, which should be made by a technology in Youzhou, even if the imitation boiler is at most enough for heating, it cannot drive any equipment without so much power, and it is easy to have an accident."

The iron used for the steam engine made the blacksmiths know at a glance, and the forging method they had never seen before could be seen at a glance, and no matter how much money they were given, there was no way to imitate it.

Li Shimin had no choice but to give up temporarily when he heard such news.

He hadn't paid attention to these things before, and the skills of the craftsmen and craftsmen had never been valued, and he also saw these drawbacks.

Think about the reason why Youzhou can develop in addition to encouragement, but also pay great attention to the skills of craftsmen, as far as the carriage is concerned, first there was a new type of bearing to make the carriage more labor-saving when pulling, and then there was the invention of the load-bearing plate to increase the load of the carriage, and later the manufacture of hollow rubber tires.

These technologies have had a huge impact on the changes in the horse fleet in the past few years, and people can't pay attention to it, just like now all the carriages in the caravan carriage field are made in Youzhou.

Because only Youzhou can buy a new type of carriage, this business alone is beyond the reach of other forces.

Li Shimin is a real project, and now there are rail cars that can replace horse-drawn carriages, and if they can really replace horse-drawn carriage transportation, there is no need to worry about the shortage of horses.

Then there are Youzhou bicycles that are now almost popular, saving a lot of time in short-distance travel.

I heard that the income from the bicycle made the city guard make too much money, even the tax revenue in Youzhou is about the same.

You must know that the value of a bicycle is 100 yuan, so it is in short supply, if this kind of transportation tool is introduced to the battlefield, although it is not as convenient as horses, but it can also save a lot of time on the road.

Although the price is more expensive than that of horses, there are many advantages, such as the bicycle only needs to be pumped without fodder, and it is very convenient to carry and walk.

If bicycles are applied to warfare, there will be many surprise attack squads, and Li Shimin will definitely arrange this if he has such technology.

It's just that bicycles are only used for daily transportation in Youzhou, and there are also many tricycles, which are said to be of great help to the business of merchants.

The popularity of bicycles has begun to affect the business of caravans in Youzhou City, because after the popularity of bicycles, merchants can deliver goods by themselves, so that they can solve a lot of money, and without business, the express delivery business will naturally be affected.

However, these Wagang cities are the same, Li Shimin can only be envious, he also wants to carry out these things, but the conditions do not allow it.

The railroad car thing really shocked many people, and many people have only heard of the new gadgets in Youzhou.

So it doesn't have much impact on ordinary people.

What's the use of envy, most people are still running around for life, where do they have the heart to think about other things.

Li Shimin thought a lot, learned about the situation in Youzhou, and then compared the situation in Wagang City, and realized that the strength of the two sides was too different.

If you want to catch up, you can't do it.

"Mowgli, Youzhou's bicycle is a money-making project, what do you think if you also build one in Wagang City?" Li Shimin asked.

"The technology of the bike is a problem." The eldest grandson Wuji said.

"If you buy key finished parts and then assemble them in Wagang, what do you think?" Li Shimin continued.

Changsun Wuji thinks about it, the parts of the bicycle are very simple, but they can't build them, but it's okay to make some wooden handlebars and pedals, but it's better to buy them directly.

"Your Highness, the parts of the bicycle are all whole, and it is not cost-effective for us to let the craftsmen build the soldiers, unless Youzhou can provide production equipment, it is said that they are all made of steam equipment, and whether Youzhou is willing to sell it is not necessarily able to agree." The eldest grandson Wuji said.

If it were replaced, he might not really agree, how could such a profitable thing be sold to others.

Li Shimin thought the same in his heart, but he knows the business model of Youzhou very well, and everything is possible only with money.

He knew very well that what Li De asked the craftsmen to study would eventually turn into profits, so he said that there were not many businessmen investing in the various workshops in Youzhou.

For example, the paper workshop, which they thought was a business that was to be in the hands of the imperial court, was not kept secret by the city guard in Youzhou at all.

As long as you meet the conditions and have the money to invest, you can get the technology.

The eldest grandson Wuji saw that Li Shimin was interested in Youzhou's technology, and if he really wanted to be able to get bicycle processing equipment, it was really a profitable industry, but was it really possible.

"Would Wuji be willing to go to Youzhou to talk about cooperation?" Li Shimin said suddenly.

The eldest grandson Wuji was very reluctant in his heart, but after all, he was not an ordinary person, he really couldn't help himself, so he could only answer yes.

So in the cold winter, Changsun Wuji set off with a caravan, the purpose of this trip is mainly to talk about cooperation, in order not to go in vain, this time the caravan will also make a purchase in Youzhou.

Youzhou City guarded the mansion, Li De learned that the eldest grandson Wuji came to discuss the matter and received it in person, no matter how much Li Xiuning had a relationship, he couldn't help but give Li Shimin some face.

He also wanted to meet the future Tang Dynasty first brother.
