The additional condition was that the Tang state's sphere of influence must allow trade, and the taxes to be followed must be carried out in accordance with the negotiated terms.

That is to say, the shops opened by the merchants of Youzhou to the forces of the Tang State must be subject to the restrictions on the negotiated terms in terms of taxation, which is very beneficial to the merchants of Youzhou.

Li Yuan had to agree for the sake of his Tang state, and the establishment of cooperation avoided war, and the joint troop dispatch operation between Taiyuan Fu and Wagang was also canceled.

Two months later, the Central Plains region became Youzhou's sphere of influence, Pei Qingxuan's work began to increase, and the integrated management of cities and counties had to occupy a lot of manpower and material resources.

Li De decided to build a large city in the Central Plains, called the Central City, which was still without a city wall, and began to allocate funds for implementation after setting up the plan.

The planning of the central city is even bigger than that of Youzhou, opening mountains and splitting stones, building bridges and paving roads, and the entire Youzhou force began to operate.

This result is what Tang Guo wants to see, and there is no time to develop Youzhou in the Central Plains, and there is no time to take care of other key business developments, where can you use swords.

The situation in the world has changed again, and Youzhou is the biggest winner in the battle of the Central Plains, and at the same time, it is really distracted by the Central Plains.

The Tang State suffered huge losses, and Li Shimin took a great advantage from it, but the internal affairs of the Tang State were still not resolved, and it can be said that they were even more intense.

Because Li Shimin's wings are stronger.

After the incident, Wagangcheng received the bicycle processing equipment made in Youzhou on time, and the factory building that had been busy for four months was ready to be completed.

Production can already start in the fifth month, and to Li Shimin's surprise, there is still a preferential price for purchasing bicycle production materials from Youzhou, but he is not responsible for transportation back and forth.

Although it is a discount, after the battle of the Central Plains, the cost of the bicycles they produce is still much higher.

The Youzhou market is still open for them.

Bicycles as a means of transportation have effectively accelerated work efficiency, especially tricycles have become the most important tool.

After the second bicycle production workshop appeared in Wagang City, it really alleviated the needs of the people in Youzhou.

The eldest grandson Wuji is now waking up with a smile in his dreams, looking at the bicycles produced every day, the cost is a little more expensive, but the sales price in Youzhou is still 100 yuan, and the tricycle is 500 yuan.

Why are tricycles so expensive, because tricycles use a lot of iron, and they are not ordinary small tricycles.

In order to meet the sufficient pulling force, the blacksmiths of Youzhou invented a double-row bicycle, the ordinary tricycle is powered by one person, and the double-row type is two people together and two self-confident chains drive the coaxial rotation.

Such a bicycle is called a cargo bicycle, which can carry twice as much cargo as a regular bicycle, and because it is used by two people, it saves a lot of effort.

The bicycle processing in Wagang City has now directly become a foundry, and their profit will be about 20% higher than that of Youzhou's processing, even in this way, they can earn 30 yuan for every bicycle sold.

It's like selling a bicycle in exchange for a horse.

The eldest grandson Wuji is in charge of this industry, and the demand for the people of Youzhou is simply shocking to him, and the 600 bicycles that were transported to Youzhou in just two months were all sold out in less than half a month.

600 bicycles is really nothing for a city with a population of one million in Youzhou, and 18,000 bicycles have been recorded in two months, which has to be concerned.

The eldest grandson Wuji is too conservative, and after getting such a sales effect, he immediately arranged to increase production, and production was in full swing.

Not only did they purchase materials from Youzhou for production, but they also began to officially provide raw materials for the materials they arranged themselves.

It's just that the price is much cheaper, the quality comparison is very critical, even if the quality can't catch up with Youzhou, but there is no problem at all with ten or eight years, no matter how it is iron, as long as it can not be destroyed, there is no problem at all.

It's just that key materials still have to be purchased from Youzhou, such as rubber tires, and this technology is not sold together.

Li Shimin now knows why Youzhou will build a rubber plantation in the south, and these are all windfall profits.

The eldest grandson Wuji really wants to follow the investment, but now the south is no longer what he wants, after all, it has become a Youzhou force, and he must be cautious in doing things.

If you want to invest in the construction of rubber plantations, you can only apply through the official application of Youzhou, but the classification of rubber is a strategic material in Youzhou, and no one else can apply except for businessmen registered in Youzhou.

If you want to control some people to be the boss behind it, I'm sorry that Youzhou's audit can't be passed, and even if it succeeds, the purchase and sales of rubber will be controlled by Youzhou.

At present, there is really no other way to sell it to Youzhou officials, and no one wants to buy it if you want to find another way, and if you want to use it, it is a matter that needs to be solved first.

Although they wanted to get involved in the money-making industry, they could only watch, which also made Li Shimin decide that he must pay as much attention to the innovation of craftsmen as Li De.

When the steam engine in the bicycle workshop really started, Li Shimin saw a new kind of power, and in his opinion, if these forces were mastered, they would definitely give Wagang City a new future.

For this reason, he did not hesitate to spend a lot of money to recruit craftsmen to start research on the steam engine, although the theoretical technology is very simple, but the cost of copying it is very large.

After the operation of the eldest grandson Wuji and others, the steam engine was not built, but began to imitate the water jacket furnace, there are many rich people, and a lot of orders have been received through the promotion of the family method.

So the blacksmiths in Wagang City were happy, and the steady stream of orders had been able to make them a lot of money.

The accumulation of Wagang City is increasing rapidly.

Li Shimin suddenly knew why Li De attached so much importance to craftsmen, although he regretted it a little too late, but for him he was trying his best to make up for it.

Looking at Li Yuan in Chang'an, the courtiers felt safer after paying the compensation, but they had to work hard because of the strength of Youzhou.

Li Yuan is a capable person, after this incident, he focused on business, not that he changed his mind, but reality had to let him do it.

The expenditure of one million guan in compensation has a great impact on the development of the Tang Kingdom, and the courtiers may not feel it, but as the emperor, he knows very well how long it will take to accumulate one million guan, not only a matter of time, but also to pray that the heavens will not make trouble for him.

Li De is currently studying what projects to come up with to recover some funds, the development investment in the Central Plains region is more than he imagined, and there is no way for the continuous expenditure not to be emptied even if it is the Youzhou treasury.

The main reason is that the basic development is too weak, and it is completely starting from scratch, especially when it comes to the construction of the central city, so that the people who have migrated in the past must not have a place to live.
