Datang: Li Er, are you teaching me how to do things?

Chapter 194

The weather is getting colder and colder, and it is snowing again in Chang'an.

Today the roosters shrank and did not report the time on time.

Li Yun woke up at about 06:30 in the morning.

"Ding! Congratulations to the host for successfully punching in the card, and reward the host for the amateur primary knowledge specialization in coal mines."

A huge amount of information came into Li Yun's brain, which surprised him, this time it turned out to be about coal.

To say that the most important energy source for future generations is undoubtedly coal, followed by oil.

China in the later generations is the world's largest coal-producing country. Even if Li Yun doesn't understand, he still knows some coal mine knowledge. At this time, he received the information from the system.

Only then did I realize that coal was found in the Shan Hai Jing. At this time, coal was called graphite, or coal.

Before the Song Dynasty, coal was not a kind of fuel, but a kind of rock, which could be used to sculpt some handicrafts.

Other than that, no one burns with coal.

The biggest reason is that the gas burned by coal products is poisonous, and the ancients were afraid, so it was not until the Song Dynasty that coal was gradually used as fuel.

However, from the Song Dynasty to the Qing Dynasty, there was a full period of about 700 years. In fact, coal mining was relatively backward and relatively simple.

There is no large-scale excavation team, but scattered ones. The common people go to pick up open-pit coal when they have time, or dig coal in the hole when they have time.

Because of the gas, the ancients did not dare to collect it on a large scale, so the development was limited.

It was not until later that the great powers opened the gates of the Qing Dynasty with ships and guns that some modern ideas were introduced about coal mining, and large-scale collection began.

In fact, there is no innovation in mining technology, the most important thing is to greatly improve the ventilation, drainage and safety of coal mining.

It made people at that time realize that mining coal was not so dangerous, which made coal mines quickly become popular in China.

So if the system keeps rewarding Li Yun for his knowledge of coal mining, he can actually directly copy the specifications of the coal mining system of later generations to improve coal mining safety and coal mining efficiency.

This coal is an important state-owned resource, and coal mines of later generations need to apply to the state for approval.

Li Yun felt that if he mastered the coal mining technology, he could bring a very rich sum of money to Datang.

Then he got up and walked out the gate of the palace, looking at the vast expanse of whiteness, thinking of Tagulli who was playing in the snow in front of him a few days ago, he couldn't help but feel a little disappointed.

The matter in Longzhou has come to a perfect conclusion, everything has come to light, and Taoist Qingming has also received the justice he deserved.

He just returned to Chang'an from Longzhou yesterday, but Tagulli left a note and then left.

She wrote on the note that she still wanted to venture into the rivers and lakes, and when Datang attacked Kang, she would come back to assist Li Yun.

It will be more than ten years after the Tang Dynasty manages the Western Regions. As for the attack on Kang, I don't know if it will happen.

Li Yun naturally likes Tagulli, but even if he is the prince, he has no face to force him to stay. After all, he still has Wei Wanyu, Xiao Mei and Fang Yiyu, so he really has no face to keep Tagulli.

So he didn't go out to look for it, and let Taguli and her group of little sisters leave the East Palace.

"Your Highness, if you have something to do with your Majesty, please go over and discuss it with your Highness."

There was a message that the eunuch was coming, Li Yun nodded, then washed and ate breakfast.

An hour later, Li Yun came to the Tai Chi Hall and found that many people were here, including Wei Zheng, Changsun Wuji, Xiao Yu and others.

Sitting on the dragon chair, Li Er slowly explained the reason for summoning everyone today.

The Household Department, which was originally in charge of Xiao Yu, has been under increasing pressure recently. Datang is about to prepare for a war with Dong Tujue, but Datang does not have much money now.

Xiao Yu really had no choice but to report the truth to Li Er.

In fact, Xiao Yu cannot be blamed for this incident. After all, the taxes have been collected, and then the expenditures of various ministries have also been distributed. Now we have to prepare for a war of unknown scale.

The pressure on the household department is naturally very high.

Wars in ancient times lasted a very long time, and they were definitely not resolved in a few days as described in later novels.

For example, Cao Cao and Yuan Shao confronted each other in Guandu for several months. How much was the consumption of this war?

Also, the Mongols besieged Xiangyang. It took several years. How much was this consumption?
The war between Datang and Dong Tujue was naturally not fought in Datang, but in the grasslands. However, it is estimated that it will take two or three months to send troops from Chang'an, and the follow-up battle may also take several months.

Calculated in this way, if everything goes well, this war will take half a year. If it doesn't go well, it will take longer and consume more.

So Xiao Yu and other officials from the household department have aged several years recently, and they constantly deduce various situations and the money needed to deal with them.

There is no doubt that, no matter how you speculate, the Ministry of Finance does not have enough money.

Li Er understood this, so he didn't blame Xiao Yu, but called all the ministers over, and everyone brainstormed how to make money.

Li Yun thought of coal, and his heart moved, but he didn't immediately step forward to say it.

Because the current system rewards are not enough, he only understands some superficial coal mining business, which is not enough to support him to stand up and pretend to be a beep.

If the system rewards conveyed all the knowledge of the coal mine, then Li Yun would naturally be able to stand up and talk freely.

If Li Yun is silent, others will naturally not be silent.

The vast majority still suggested increasing the business tax, and no one said the agricultural tax.

Because whether it is Wei Zheng or Changsun Wuji, the status of farmers is actually higher than that of businessmen in their hearts.

In the eyes of these court chiefs, farmers are the foundation of a country, and farmers must not be messed up.

But merchants are the ones who can be sheared at any time. If the imperial court is in trouble, it is natural to take the merchants into action.

There are also a few people who oppose it, but there are only a few people, and it will not be successful.

So the vast majority of people later supported the use of businessmen.

At this time, Xiao Yu said slowly: "My lords, this year's commercial tax has already been paid, and even if the commercial tax is to be increased, it will have to wait until next year."

"What's more important is that the increase in business tax is not enough, we need more other means."

Datang’s commercial tax is generally ten-tenth tax, that is to say, ten percent of the goods are used to pay taxes.

In the eyes of later generations, it can be regarded as high, but in the feudal period, such taxes were very low, even lower than the taxes of the Song Dynasty, which had developed commerce and trade.

On this basis, even if the tax is increased, the commercial tax will not be very high.

So Xiao Yu felt that it was not enough at all.

Li Er frowned slightly, he had already advocated the simplification of life in the palace, he and Empress Changsun's clothes and food had been reduced a lot.

But the money saved is not enough.

All the princes in the court can think of is collecting taxes. As for other businesses, they don't have that idea.

Thinking of this, Li Er turned to Li Yun, "Prince, what do you think?"
