In this era, there was no such thing as a mining tax, and the main mineral products in circulation were iron products.

At this time, people's understanding of mineral deposits was relatively shallow, and they basically knew about gold, silver, copper, and iron, which were once used as currency exchange.

Even if other mineral deposits are discovered, they don't know how to refine and use them, so they can only use them to refine the elixir for the emperor to seek immortality.

This is enough to prove that except for the traditional metals such as gold, silver, copper and iron, most of the mineral deposits have not been rationally used in the social economy.

Therefore, before Guo went on a large scale to mine the raw materials for making gunpowder, there was really no one who knew that sulfur and saltpeter were used for such purposes, and they were all used to refine the elixir.

After Guo established the Duchy of Wei, he began to design some systems for mineral deposits.

At the same time as the official management system of salt and iron was established, a system was established that all mineral deposits should be returned to the public and private mining was not allowed, and laws were established to confirm it.

The mines were all under the management of the government, and the government sent people to mine them, and then made them into various finished products, or turned into commodities for sale, or turned into weapons and put in arsenals, or sent to the central government to mint money.

Then all revenues go to the state treasury.

Although it is said that a part of the annual treasury revenue is allocated to the inner treasury for royal funds, it is obviously not worth mentioning compared to the huge expenditure of Guo someone.

Therefore, Guo thought of taking the initiative to send people to explore undiscovered mineral deposits to come to mining, using the manpower and material resources of the two caravans to organize mining and production, and the income obtained was charged to the inner treasury to increase the source of income of the inner treasury.

The courtiers didn't dare to talk nonsense.

If they make more money, will they not receive much reward?

The emperor is so capricious.

So Guo praised Su Yuan happily.

"You've done a good job."

Guo looked at Su Yuan: "Su Yuan, you are responsible for this matter from beginning to end, so I will leave the matter of mining to you, and you will send people to connect with the Cao family caravan and the Mi family caravan." ”

Su Yuan was obviously surprised.

"Your Majesty, old slave...... The old slave just wants to serve His Majesty and doesn't want to do such a thing. ”

Su Yuan immediately knelt in front of Guo Peng.

"I didn't let you go, you are still waiting by my side, opening the mine is opening the mine, you just send someone to watch it, do you think I need you to go to the mine to pick a hoe in person?"

Guo Peng patted Su Yuan on the head: "I'm going to set up a new official office in the inner court dedicated to managing mining operations, just right, aren't you jokingly called the head of the eleventh prison?" Let him sit down, what is the name of this eleventh prison? ”

Guo Peng walked around in front of Su Yuan and suddenly smiled.

"If you have it, let's call it Dongchang."

"East ...... East Factory? ”

"Well, Dongchang."

Guo Peng said with a smile: "There is nothing else to mean, I suddenly feel that this name is very interesting, this East Factory, just take charge of mining affairs, you are my personal internal official, you will take care of it, I can rest assured, the internal official has a very heavy authority to supervise the money, and the mineral income cannot be handed over to the internal official supervisor to manage." ”

Guo Peng patted Su Yuan's shoulder.

"Get up, factory."

"Your Majesty...... Old slave, old slave dare not be called such a title. ”

"I gave it to you, you just take it, what, don't you want it?"

"No, no, no, the old slave doesn't dare, the old slave ...... Old slave thank you Your Majesty Longen! ”

Su Yuan knelt down again.

"Well, then go ahead and do it, do a good job of all the mines, mining, smelting, and then make a profit, the more money I make, the more money I have, the more I can do things, you don't have to care about other things, the sky is falling, I will hold it, you can give me all the strength to open the mine."

Su Yuan nodded immediately.

"The old slave understands."

So, in the first month of the fourth year of Yande, the Dongchang of the Department headed by the eleventh eunuch of the Inner Court was born.

Unlike the Ten Eunuchs of the Inner Court, the headquarters of the East Factory was set up outside the palace, and in order to facilitate mining, the members were not all eunuchs, but also normal men.

Su Yuan, the factory prince in charge of the East Factory, was the eunuch next to Guo Peng, so the East Factory was also one of Guo Peng's directly governed departments, which was responsible for the income from mining and then sent the income from mining to the inner treasury and handed over to Emperor Guo Peng for free disposal.

By the time the courtiers learned the news, it was already February of the fourth year of Yande.

The news that Yu Ban led the army to pacify the Fuyu Kingdom came from the eastern Liaodong frontier, and the opening of Pingzhou was officially completed.

Then the courtiers heard the news that the emperor had set up the eleventh department of the inner court, the East Factory, which seemed to be the department to manage the income from mining.

Later, when the emperor officially announced that the East Factory was responsible for the income from mining, the courtiers knew that the emperor had quietly made an established fact for everyone to bear.

The emperor searched for mineral deposits throughout the country to open mines, and all the income from mining was collected into the inner treasury and returned to the emperor for free expenditure.

Although it is said that the mine was explored and mined by the emperor himself, isn't your emperor doing this to rob the treasury for money?

This time it is not a competition with the people, but there are still courtiers who discuss this matter, the emperor did not do well, and there is a suspicion of eating ugly.

In response to this criticism, Guo Peng issued an edict, saying that the inner court would pay taxes in full accordance with the laws and regulations of the imperial court to lead the caravan to operate the mines, and the taxes would not be less than a penny.

But this money, the emperor is going to decide.

Everyone understands that this is the biggest concession the emperor can make, and if he does it again, the emperor will be angry.

Nothing can make the emperor angry, this is something that everyone agrees on.

After that, Guo Peng opened the inner treasury and took out a large amount of property and sent it to Liaodong to reward the soldiers, and the courtiers completely shut up and didn't dare to say anything more.

Guo Peng did this to tell the courtiers that the inner treasury was his personal small treasury, but when necessary, he would also take it out for the imperial court.

If you don't let me open the mine, you will pay for this money, and I will have no money.

This matter is confirmed for Guo Peng.

His inner treasury has an extra source of wealth, and his future income can be expected, so he doesn't have to shrink back in many things, and this time he will have more rewards for the soldiers of Liaodong.

However, Yu Ban was able to destroy the Buyeo Kingdom in such a short period of time, which Guo Peng did not expect.

Later, after the joint recital of Pingzhou Assassin Shi Lusu and Zhengbei General Yu Ban was sent to Luoyang, Guo Peng learned how Yu Ban destroyed the Buyeo Kingdom within a month.

To be precise, it's a simple decapitation tactic.

Yu Ban didn't tell anyone, and personally led the cavalry to run hundreds of miles to smash the Buyeo King City, wiped out the Buyeo King and the royal family, and directly wiped out the Buyeo Kingdom.

The reason is very simple, Yu Ban received a secret report, saying that the king of Fuyu was hiding the daughter of Gongsun Du, with bad intentions, and there was a possibility that he would secretly help the remnants of the Gongsun clan to occupy Liaodong.

After Yu Ban learned about it, he decided to keep quiet first, and then personally led his troops to attack for hundreds of miles, and unexpectedly attacked the capital of Buyeo State, destroying Buyeo State in one fell swoop.

Then the Wei army arrived quickly and pacified the other forces in the Buyeo State that had not yet reacted, and the Buyeo State was eliminated in only a month.

Eliminated the restless existence that might grow in the future and threaten the safety of Pingzhou in the Wei Empire.
