Datang is big, but there are also many problems. After the prince went to the county, he didn't sit back and relax.

There is also the problem of the army, it is still an old saying, the Tang Dynasty does not make money when it fights small countries, it loses money. But if they don't fight, the Tang army is not happy, because they are just waiting to make money from the war. If they don't fight, they will have no income.

There are also gate lords and aristocrats in various places, who still make trouble from time to time, although they are not talking about rebellion, but the policy of the Tang Dynasty is always discounted, either asking for money, or it is yang and yin.

Of course, all departments in the court want money when they open their mouths, and they want to compete with the people for profit when they close their mouths. Anyway, being an emperor is worrying about money every day, this needs money, that needs money, that needs money, that money needs money, and that money is needed for war, and peace also needs money, and there is no place where you don't need money anyway.

Today the water will be repaired, tomorrow the roads will be tidied up, and the day after tomorrow the ordnance will be renewed and the city walls will be renovated. In fact, the ordnance update is the least in a hurry, because several foreign wars of the Tang Dynasty have ended, and there are no small countries around that dare to make trouble. You can put knives and guns into Kuma and put Nanshan, but if you really don't update it all the time, you will inevitably have to suffer at that time.

So this is a very contradictory question, there is no enemy who can confront Datang, so why should Datang spend money to make more advanced weapons? Advanced weapons were invented when the two powers were in confrontation, and when one power became dominant, the weapons were useless, and at this stage, no matter how strong the weapons were, they were rusted in the warehouse, because there was no place to fight, and it would lose money to fight a small country, and there would be no goal in fighting a big country.

For a big country, it is not cost-effective to maintain a high cost of armaments, and there are various problems within Datang that cost money, so Li Shimin is ready to cut the budget of the Ordnance Administration. Because as far as the future is concerned, it is estimated that there will be no more large-scale battles in the next ten years, and even if there are small-scale conflicts, the old weapons will be enough.

This problem has also been encountered in the Qing Dynasty, before the First Opium War, the weapons of the Qing Dynasty have always been the top in the world, the question is who to fight? There is already a goal, and it is a loss to fight a small country, and it is enough to use a knife to kill chickens and fight a war of law and order with old weapons. There is no strategic goal at all, and naturally there is no need to develop advanced weapons, and then they will be taught by foreigners to be human.

From the point of view of studying weapons, it is best to have one enemy, otherwise advanced weapons are useless.

It's like a young couple living a life, the income of the young couple is fixed, but the husband wants to buy a game console, and the wife wants to buy some furniture for the small family. What is the use of a wife just saying that a game console? The husband can only obediently give the money to his wife. But if one day, the game console becomes a prop for several families to compare, then the wife will definitely support her husband to buy the game console.

If the Ordnance Department wants to budget for the invention of new weapons, then other departments will say in a minute that they can't use it to repair water conservancy and maintain the city wall. These are all really doing things for the people, and what's the use of inventing new weapons?

The war has ended, peace has come, the Tang Dynasty looks around, the Turks have been defeated, Goguryeo has surrendered, and the Tibetans have accepted the peace relationship, who else dares to challenge the might of the Tang Dynasty now?! No, it's invincible.

To create a new weapon, you must have an enemy.

Previously, Yun Yao thought that in order to maintain the combat effectiveness of the Tang Army, the Tang Army could be used as mercenaries, but mercenaries did not need any advanced weapons, and the old weapons could be improvised. But if you only use old weapons and do not develop new ones, you will still fall behind sooner or later.

"It seems that invincibility is also a disadvantage." Yun Yao thought to herself that it really made sense for the Heavenly Dao to make up for the deficiency, and Datang's attributes in all aspects were too rebellious, so that he didn't know what to do next.

Now, even if Datang discovers the New World, I'm afraid that there is no motivation to colonize, because the surrounding small countries have not been developed, so they will go to the colony for development? Isn't this sick?

Even Yun Yao could not convince the Manchu ministers to develop new weapons and maintain the expenses of the Ordnance Administration.

Because there is no enemy at all, if she wants to maintain the armament budget, she will definitely be labeled as a reckless soldier. So Yun Yao had nothing to say, he could only blame Li Shimin for being too active in the war and not leaving an enemy for Datang, even if it was an imaginary enemy.

There are many places to spend money, so we can only tear down the east wall and make up the west wall, but fortunately, since the official Shanhai, the salt and iron monopoly has always been the main source of income for the state treasury, and it is not so much that there is no money.

The treasury has money, but if there is money, it can't be squandered, Li Shimin is still careful in his calculations, and the money is spent on the blade. With the advent of peace, there are really more and more places to spend money. However, when all countries came to the court, trade was booming, and the rule of Zhenguan was still very golden.

Li Shimin thought of the industrial upgrading that his daughter had been talking about, so he was thinking about whether to set up an industrial bureau, an official of Zhengliupin, to make money specifically for Tang. In the past, the money earned by his daughter was given to shareholders and herself, although Li Shimin is also a shareholder, but this money is his own private money and does not belong to the treasury. And now he is thinking about whether to let his daughter make some money for the Datang treasury.

Although it is a petty official of the sixth grade, you can try it. Li Shimin wants to test the water with 100,000 guan first, if Yunyao can really make more money, then it is also possible for the Industrial Department to upgrade to the Industrial Temple, and when the time comes, it will be on a par with Dali Temple, Honglu Temple, etc., which is the fourth product.

If you earn more, you can continue to upgrade to the third product.

However, this matter still needs to be discussed with the minister, and after arranging the prince, it is time to arrange the princess. Yun Yao is also almost twenty years old, although she looks light and young, but her age has arrived, and it is time to take on more responsibilities.

The ministers still agree with Yunyao's earning ability, and they have also heard of Yunyao's industrial upgrading. Over the years, there have been many new things in Chang'an, which can be called the product of industrial upgrading. Stronger printing technology, stronger means of transportation, and more delicate small objects. These are all made by the princess, if you can really make money for Tang, of course it is a good thing, after all, there are more and more places to spend money, and you can't just throttle and open source.

And it's just the position of the sixth product, just to test the water. Besides, the princess makes money, and the minister spends money, why should they object? So it's easy to get through.

So Li Shimin drafted a decree to establish the Datang Industrial Upgrading Agency, and Yun Yao served as the commissioner, responsible for making money for Tang. From the official position of the sixth grade, the money is 200 yuan a year, 400 quintals of rice, and 20 yuan of miscellaneous expenses.

It's barely okay to live in Chang'an for 200 yuan, but fortunately, Yunyao doesn't need to rent a house, she lives in the Horse Mansion, and the carriage and horse fees don't cost money, and there are luxury cars to pick up and drop off. This feels like the rich second generation has experienced at the grassroots level of the company, it doesn't matter how much the salary is, what you want is this atmosphere, high-end apartments live, famous cars are driven, although you commute with grassroots employees, but people don't care about this salary at all.

Two hundred? This amount of money can't even support the pets of the Horse Mansion. Yun Yao's income is still his own invention dividends and fiefdom taxes. So this is really what it means, make an attitude.

"I didn't expect to be a princess, but I have to go to work." Yun Yao suddenly thought that this was the real punishment, isn't working in the mortal world a sentence? At the age of twenty, he began to grow old, but fortunately, Yun Yao didn't have to worry about material life, otherwise the punishment of Heavenly Court would be too cruel.

Go to work, just go to work, and start serving your sentence officially.
