The raw materials that limit the yield are always the raw materials, and the cultivation of herbs is not as good as grain, so it is not easy to promote them. Moreover, herbs depend on the season. However, elixirs cannot be provided seasonally and must be produced throughout the year.

Yunyao produced glass, built a greenhouse, and solved the seasonal problems. Then he promoted medicinal materials in the Royal Farm. Originally, the grain produced by the Royal Farm was the royal special supply, but now it is not necessary. He would rather go out to buy grain and meat than solve the raw material problem first.

Li Shimin supports Yunyao very much because he wants to see how Yunyao upgrades the industry. So as long as he can support it, he supports it.

The ministers now know that the elixir was actually produced by the royal family, not a secret medicine in the Western Regions at all, but the effect is indeed very good, but the output is not high. So His Majesty is anxious and knows that everyone needs elixirs, so he strives to promote the production of medicinal materials and expand the production scale. The elixir will definitely be enough in the future. At present, everyone can only tolerate the current situation of high prices and low volume.

No matter how high the price is, you have to buy it, although they are not useful. It is worth it to be able to use money to revive your strength, no matter how expensive it is.

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

Li Shimin was surprised that his daughter not only knew how to refine elixirs, but also glass. Is it an ancient recipe? In fact, glass is just burning sand, which means that the temperature requirements are relatively high. Yun Yao improved the blast furnace, found coal, and increased the temperature of the furnace to 1,500 degrees. This was definitely the high temperature in ancient times.

In fact, glass was found very early, and it was not easy to burn it into glass. In the Eastern Jin Dynasty, the glass products and craftsmanship circulated abroad were recorded. However, the most magical part of this record is not glass, but the location, in Lingnan. In other words, this glass was uploaded from the sea to the Central Plains, which once again proved that the Maritime Silk Road in the Tang Dynasty was already very stable, so the Maritime Silk Road was opened to manage and collect taxes.

It can be seen that the Maritime Silk Road was no later than the Eastern Jin Dynasty, and it may have even started during the Han Dynasty, and even existed in the pre-Qin period. After all, there was a record of Xu Fu taking 5,000 boys and girls to sea. In the First Mortal, there was a case of Jiang Taigong going to sea to find Huaxu Kingdom very early. Although Yun Yao no longer had six hundred years in the mortal world and had 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 Han, when the official first determined the maritime trade route, and Yun Yao was still serving his sentence in heaven.

Burning glass requires temperature, so after the blast furnace of 1,500 degrees appears, burning glass is no longer a problem. In fact, royal craftsmen in the Song and Yuan dynasties had mastered the firing of glassware for royal use, but this thing was really very low in output and had no economic benefits. It can only be said to be a luxury product and was burned. However, glass is very important to science, for example, greenhouses solve the problem that glass cannot produce economic benefits.

Although a greenhouse is very expensive, as long as you can plant medicinal materials continuously all seasons, you can keep making money.

Glass can also make containers, microscopes, glasses, mirrors and other commodities. Although it is expensive, it can also make money, which is much better than burning luxury goods for the royal family. Therefore, the technology of the Central Plains aristocrats is not behind, but they are all at the highest level and have no motivation to upgrade.

If you just make a **, there is no profit, you will naturally be said to be a ** depressed and a strange and lewd skill. Therefore, you must upgrade.

Since they have technology but no direction, Yun Yao will bring direction and direction to make money when they come. Realizing that glass can produce economic benefits, someone will definitely start studying glass in the future.

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

"For the production of a elixir, there are so many supporting technologies. No wonder capitalism can promote the development of science and technology." To make money, it is indeed the enthusiasm of capitalism. Unfortunately, due to the endogenous contradiction of overcapacity, capitalism has to make money. It is no longer making money for upgrading industries, but making money for making money, concentrating all the working capital in society, and ultimately leading to the stagnation of social development.

In order to produce elixirs, the problem of raw materials must be solved. In order to solve the need for a greenhouse, in order to solve the problem of greenhouses, glass furnaces have been built and glass has been produced, and a batch of derivative products have emerged. The use of these derivative products will give birth to new industries.

For example, the silver mirror reaction on the back of the mirror can open the branches of chemistry.

In short, because he can make money, Yunyao is a time traveler who does not take detours or wastes money, so he plays with industrial upgrading just like a Rocket. Back then, the market was not enough in Linzi, but now Yunyao is facing the entire Tang Dynasty as a market support, and the products produced are not afraid of being unable to be sold. With a good cycle and new investments are constantly coming in, Yunyao continues to expand production.

A year later, the scale of elixir production was formed. In Li Shimin's stunned gaze, the Chang'an merchant who was ready brought the elixir and rushed to his agency area and began to expand. He really covered ten roads in one breath, which was even more devastating than Li Shimin's battle.

Li Shimin watched with greed as a large amount of currency gathered in Yunyao's hands. She was only four years old this year.

"Every time I'm worried about raising military funds, but Yun'er can collect money in large quantities. I'm jealous." The border has not yet been pacified, and Turks, Tuyuhun, and Goguryeo are still beside the bed. So now, saving money is to fight a few battles to determine the world. I'm worried about military spending, but my daughter is making money. He wishes he could take military spending from his daughter, so he would start the war immediately.

"Although she makes a lot of money, she spends more money. Now the debt she borrows is higher than that of mountain. Although these are voluntary investments, if they cannot make a return, I don't know how Yun'er will face the creditor. And these things are all caused by the prince. Once something happens, everyone will not give the prince a good face. They are only nine and four years old. Do you have to take care of it?" Empress Changsun was really frightened. These two children are too brave. They really dare to collect any investment. They are really not afraid of the business being ruined and cannot get out of the market. "It's also my fault. I was too careless at that time and let them do whatever they want. Now they can't stop it. Within a year, they have raised more than 100,000 chunks of funds, which is terrible." These money are all from others. How dare the two children do this?

Li Shimin said indifferently: "The sales of elixirs are very good. Even if the business is ruined, the prescription alone is enough to mortgage. And the more money they borrow, the more others cannot let them lose. The more they need to ensure that the business can continue. So don't be nervous, I think Yun'er has his own sense of responsibility and will not implicate the prince."

When Yun'er was born, there were strange phenomena in the sky, so she was definitely not an ordinary child. So Li Shimin was looking forward to her growth very much. Moreover, she was a daughter, and she would not threaten the imperial power and would not rebel if she had the ability.

This is to underestimate the women of the Tang Dynasty. There are many princesses who rebel in the Tang Dynasty, let alone the famous Wu Zetian. Unfortunately, the princess rebelled was a matter of the future, and Li Shimin could not predict it. If he knew, he would definitely be worried that Yunyao would follow the Xuanwu Gate Incident.
