Yun Yao's business is very profitable, but in order to develop quickly, she borrows more money. Even the queen felt scared, more than 100,000 guan is not a small amount of money, this is more than 1,700 taels of gold.

Since the fourth year of Wude, after the copper coins of Kaiyuan Tongbao were minted, the market was stable and the prices were low. I don't know how many properties can be found in the long-term resettlement office for 1,700 taels of gold, and Princess Zhu Yun is only four years old, and she has such a huge amount of money in her hands, how can she not be worried? The investment has to be repaid, what if it can't be replaced?

Although Li Shimin is optimistic about the business of the pill, Empress Changsun feels that as long as it is a business, there is no guarantee to make money, and there will always be profits and losses. And if she can make money now, according to the courage of Zhu Nu, a little girl, she may not be able to make a big deal with her small, she will definitely dare to accept more investment. If you encounter a situation where the capital turnover is not effective and you can't pay dividends in time, it will be troublesome.

Yun Yao threw a lot of money, once there is a problem with the return of funds, then the investor is not going to blame her? Worrying is not unfounded, after all, doing business can go wrong at any point. Especially after Yunyao expands like this, after spending all the money, once it is too late to withdraw the funds, there will be big problems.

It's not wrong to be worried, but Yun Yao doesn't care at all, if there is really a situation where the capital turnover is not working, she can also borrow money again, or even issue bonds, or open a money bank, there are many ways to raise funds. Besides, he has the prince's brother and the emperor's father, isn't their reputation worthwhile?

So she's unstoppable.

The agency rights of the Tang Ten Dao have all been decided, the pill merchants transport the pills from Chang'an to the east, west, north and south to sell, and the pricing power is handed over to them, although the pricing can be controlled in Chang'an City, but outside, the whip is out of reach, so it is simply not stipulated. Yun Yao couldn't control their greed.

In fact, there have been a large number of pill scalpers in Chang'an, who buy at low prices, hoard Juqi, sell at high prices, and make a lot of money as soon as they turn their hands.

From books such as "Guanzi", "Salt and Iron Theory", "The Biography of Goods and Colonies", "Three Kingdoms" and other books, we know that in fact, the gameplay of economic means is basically like this, and even in the period of Sun Quan of the Three Kingdoms, he also harvested the wealthy families in Jiangnan through the coinage right. His methods are also very direct, originally if a copper plate is one dollar, then he slightly increases one-tenth, and the direct price is ten yuan. It stands to reason that the value of metal currency is proportional to its weight, and it is one-tenth heavier, that is, 1.1 yuan, which is not worth ten yuan at all. But Sun Quan directly stipulated that this was ten yuan, and then used 1.1 weight currency to buy ten yuan of goods.

Trade wars and currency wars are not unusual, so various economic links have long appeared, such as scalpers, which are really bustling all over the world for profit, and all the hustle and bustle in the world are for profit.

By the time of the Tang Dynasty, foreign wars were no longer profitable, and even after the destruction of Goguryeo, no actual ruling force was formed, and then there was a Bohai State, which only belonged to the Tang Dynasty. After arriving in that place, the Khitans established the Liao State and the Jurchens established the Jin State.

The main reason is that the Tang Dynasty is surrounded by small countries, and it is a waste of money to fight down, so trade has become the main foreign mode since the Tang Dynasty. As long as the two Silk Roads are in their hands, there is no motivation to fight out at all, and now there is no such thing as mining and oil that can make money, so the great unified dynasty after the Tang Dynasty is not very happy to fight it.

Of course, the Song Dynasty does not count, because the Song Dynasty was not unified at all, neither the Northern Song nor the Southern Song Dynasty completed unification, and a large amount of land was lost.

Among the three dynasties of the Yuan, Ming and Qing dynasties, the Ming Dynasty did not expand outward, but Zheng He went to the West to strengthen the Maritime Silk Road.

It was also the expansion of the Yuan and Qing dynasties, because they both entered Huaxia from the outside, and they did not accept the rules of Huaxia's game from the beginning, but after they lived down, they would know that Huaxia's game was really lying down and counting money, and there was no need to fight to the death.

The attitude of the Central Plains towards the vassal countries and barbarians is also very casual, as long as everyone does business. However, when the colonists slashed the butcher's knife at the barbarians, the game that had lasted for thousands of years of Chinese civilization was destroyed, and the Chinese civilization realized that the colonists were still playing the game of Spring and Autumn.

Since reunification, the mode of survival of the great powers has changed, and the millennium of continuous exploration has brought about tremendous changes both internally and externally.

Yun Yao thought that if he really didn't have any money, he could form a Datang mercenary, although Datang didn't make money from wars, but it was still possible to make money by renting out soldiers, especially those small countries around it were not peaceful. Datang wants to raise soldiers anyway, so it is better to treat it as a business, and it is estimated that it can make a lot of money.

However, these must wait until Li Shimin has finished fighting the Turks, Goguryeo, and Tuyuhun. If there are no strong soldiers, it will be very unlucky if you have money and no soldiers, and if you are weak, you will not necessarily be beaten, and if you are weak and have money, you will definitely be beaten.

The Central Plains civilization is too rich, so that later, whether it is a foreign race or a feudal town, they all squeeze their brains to enter the Central Plains, if there is no army and the corresponding management system, then the money is also earned for others, and the Central Plains is at best a money jar, anyone can knock on it and grab it.

Yun Yao thought of military wars from trade wars and currency wars, and also had some thoughts because of his elixir business, after all, when the business started, there would be all kinds of challenges next, and there would always be a time when these three kinds of wars were used.

"Hey, it's not easy to concentrate on making money and upgrading the industry, internal and external troubles." Yun Yao said that it is not easy to be a civilization that makes money quietly.

But since you don't have to stop at the beginning, as long as you have the money to upgrade the industry, then the weapons and equipment will naturally rise, and you will naturally click on the scientific technology tree.

However, Yun Yao is really too difficult to be alone, and he still has to find a way to cultivate more scientific and technological talents. Why don't you open a school with the next sum of money? Or invent a printing press first?

Yun Yao has done it all over again in the first mortal world, and now she has done it again in the second mortal world, and she is very familiar with it, and even where she has the resources she needs, she has already backed it. It's just that many things in the first mortal world are directly used for mana, while in the second mortal world, you may need to find the corresponding materials.

For example, adhesives, lubricants, sealing rings, bearings and the like were all used in the first mortal world to replace them with the mana of the earth immortals. But in the second mortal world, you have to find different materials such as glue, grease, rubber, metal, etc., and the steps are much more troublesome.

There is no way, who let the second mortal world be completely handed over to the management of mortals, and it is difficult for immortals to interfere. Yun Yao is also theoretically a mortal now, so he can only do it in the way of mortals.

"It's better to invent the printing press first, and there is cheaper papermaking." Yun Yao made a decision to get the printing done first. After all, only cheap books can spread knowledge more widely.

By the way, the Chinese typewriter was also invented, and without computers and spells, it is not easy to type Chinese characters. But after all, it has to be solved, Yun Yao said that she has "Craftsman Technique", a bonus of craftsman spirit, since the invention of Yuanxi, as long as she wants to make any mechanism, there is always divine help.

So Yun Yao started to tinker again, anyway, she was not interested in the games of the royal family fighting for power, so it was better to concentrate on research.
