It is always the raw materials that limit the production, and the cultivation of medicinal herbs is not comparable to grain, it is not easy to promote, and medicinal herbs also depend on the season. However, the pill cannot be provided seasonally, and must be produced all year round.

Yunyao produced glass, built greenhouses, and solved the problem of the season. Then there is the promotion of medicinal herbs on the royal farms. Originally, the food produced by the royal farm was specially supplied by the royal family, but now it is not needed, and I would rather go out to buy grain and meat, and I must first solve the problem of raw materials.

Li Shimin is very supportive of Yunyao because he wants to see how Yunyao upgrades the industry. So as long as it can be supported, it is supported.

The ministers now also know that the pill is actually produced by the royal family, and it is not a secret medicine of the Western Regions at all, but the effect is indeed very good, but the yield is not high. Therefore, His Majesty is anxious and knows that everyone needs pills, so he makes every effort to promote the production of medicinal materials and expand the scale of production, and the pills will definitely be enough in the future. At present, everyone can only put up with the status quo of high prices and low quantities.

No matter how high the price is, you have to buy it, even if they don't use it. If you can use money to reinvigorate your strength, no matter how expensive it is, it is worth it.

Of course, Li Shimin would never let anyone know that this elixir was refined by his daughter.

The daughter can not only refine the elixir, but also the colored glass, which surprised Li Shimin, is it also an ancient recipe? In fact, glass is just burning sand, but the temperature requirements are relatively high. Yun Yao improved the blast furnace, found coal, and raised the temperature of the furnace to 1,500 degrees, which is definitely the high temperature in ancient times.

In fact, the glass has been there for a long time, but it is not easy to burn into glass, and there is a record of the glass products and processes that have been circulated abroad in the Eastern Jin Dynasty. However, the most amazing part of this record is not in the glass, but in the location, in Lingnan. In other words, this glass was transmitted to the Central Plains from the sea, which once again proved that the maritime Silk Road was very stable in the Tang Dynasty, so the city shipping department was opened to manage and collect taxes.

It can be seen that the Maritime Silk Road was not later than the Eastern Jin Dynasty, and may have even begun in the Han Dynasty, and even existed in the pre-Qin era, after all, there were records of Xu Fu taking 5,000 boys and girls to sea that year. And in the first mortal world, there was a long time when Jiang Taigong went to sea to find Huaxu Kingdom. Although Yun Yao has been in the mortal world for six hundred years and has not paid attention to the maritime trade in the second mortal world, it must have been very early, and it was basically perfected by the Tang Dynasty.

In fact, the exact time was during the reign of Emperor Wu of the Han Dynasty, when the official first determined the maritime trade route, and Yun Yao was still serving a prison sentence in heaven at that time.

Burning glass requires temperature, so after the advent of 1,500 degree blast furnaces, burning glass is no longer a problem. In fact, the royal craftsmen of the Song and Yuan dynasties have mastered the firing of glassware for royal use, but this thing is really very low in production and has no economic benefits, it can only be said to be a luxury product, burned and played. However, glass is important for science, for example, greenhouses solve the problem that glass does not produce economic benefits.

Although the cost of a greenhouse is very expensive, as long as you can grow medicinal herbs all year round, you can continue to make money.

Glass can also be used to make containers, microscopes, glasses, mirrors and other goods, although expensive, but it can also make money, but it is much better than burning luxury goods for the royal family. Therefore, the skills of the nobles of the Central Plains are not lagging behind, but they all stay at the level of playthings, and there is no motivation to upgrade.

It's just making playthings, and there is no profit, so it will naturally be said to be a plaything and a trick. So it has to be upgraded.

Since they have technology but no direction, then Yun Yao came and brought direction, a direction that can make money. Realizing that glass can produce economic benefits, someone will definitely start working on glass in the future.

With glass, many derivative products can be made, mirrors, glasses, binoculars, Yun Yao said that these things are all made by the way.

"For the production of an elixir, there are so many supporting technologies, no wonder capitalism can promote the development of science and technology." In order to make money, you have to overcome difficulties, which is indeed the enthusiasm of capitalism, but unfortunately in the end, because of the endogenous contradiction of overcapacity, capitalism has to go to the point of making money, no longer to make money for the sake of upgrading the industry, but to make money for the sake of making money, and to concentrate all the liquid funds in the society, which eventually leads to the stagnation of social development.

In order to produce pills, the problem of raw materials must be solved. In order to solve the problem of raw materials need greenhouses, in order to solve the problem of greenhouses, glass furnaces have been built, glass has been produced, and a number of derivative products have appeared. And the use of these derivative products will give rise to new industries.

For example, the silver-plated silver mirror reaction behind the mirror can open up the branch of chemistry.

In short, because he can make money, Yunyao is a traverser who does not take detours and does not waste money, so playing industrial upgrading is just like a rocket. Back then, in Linzi, the market was not enough, and now Yunyao is facing the entire Datang as the market support, and the goods produced are not afraid of not being able to sell at all. With a good cycle and new investments coming in, Yunyao will continue to expand production.

A year later, the scale of pill production was formed, and in Li Shimin's stunned gaze, the Chang'an businessman who had been prepared quickly rushed to his own agency area with the pill and began to expand.

Li Shimin watched with greed as a large amount of currency gathered into Yun Yao's hands, she was only four years old this year.

"Every time I worry about raising military salaries, Yun'er can collect a lot of money in her hands, and I look red." The border pass has not yet been pacified, and the Turks, Tuyuhun, and Goguryeo are still on the side of the couch. So now the frugality is to fight a few big battles that will determine the outcome of the First World War, and he is worried about the military expenses, but his daughter is accumulating money, and he hates to take the military funds from his daughter, so that he can start the war immediately.

"Although she makes a lot of money, she spends more money, and now her debt is higher than a mountain. Although these are voluntary investments, if you can't return the capital, I don't know how Yun'er will face the creditor. And these things are all done by the prince, once something happens, everyone will not give the prince a good face, they are only nine and four years old, are they a little careful? "The eldest grandson queen is really frightened, these two children are too bold, they really dare to accept any investment, they are really not afraid that the business will be yellow, and they will not be able to get off the stage." I also blame me, I was too careless at the time, I let them come nonsense, and now I can't stop it if I want to, within a year, they have raised more than 100,000 yuan, which is terrible. "This money is someone else's, how dare the two children do this?

Li Shimin said indifferently: "The sales of the pill are very good, even if the business is yellow, just the prescription is enough to mortgage." And the more money they borrow, the more people can't let them be yellow, and the more they have to make sure that the business can continue. So don't be nervous, I think Yun'er has her own measure, and she won't affect the prince. ”

When Yun'er was born, there was a vision in the sky, and it was definitely not an ordinary child. So Li Shimin is very much looking forward to her growth, and she is still a daughter, and she will not threaten the imperial power if she has the ability, and she will not rebel.

This is to underestimate the women of the Tang Dynasty, there are many princesses who rebelled in the Tang Dynasty, not to mention the famous Wu Zetian. It's a pity that the princess's rebellion is a matter of the future, Li Shimin can't predict the prophet, if he knew, he would definitely worry that Yun Yao would follow the Xuanwu Sect's changes.

Therefore, Yun Yao was reincarnated as a princess, which made Li Shimin a little less suspicious and a little more father-daughter relationship.
