Datang: The prince of salted fish was overheard by Li Er

Thinking of this, Li You didn't say that he was going to leave, but stood quietly beside Li Shimin, waiting for the arrival of several people.

Soon, these four people appeared in Li Shimin's study.

Seeing Li You in the imperial study, the four of them were surprised again.

In the end, Wang Xiaotong said, "My lord, it's fine if you stay here. I was anxious because I couldn't find my lord when I went to the palace."

Seeing that Li Shimin was not ready to answer, Li You said, "I have something to discuss with my father, what's the matter?"

"Is there something wrong with the national debt?"

Wang Xiaotong shook his head, then turned to look at Dai Zhou.

Only then did Dai Zhou take over the conversation and said: "There is no problem with the national debt. We invited Mr. Wang to come over to help with the calculation."

"This time it was Datang coins that had an accident!"

This time it was Li You's turn to be surprised. He had just helped Kang Jie out of the siege, and Hou Junji sent troops out to Shicheng to exchange the gold and silver in Kang Yandian's hands. At this juncture, how could something happen to the Tang coins.

Under Li You's gaze, Dai Zhou talked about the past few days.

In fact, things are somewhat similar to the grassland bond incident issued by Li You back then.

In the past two days, someone came over with a large amount of Datang coins and asked to exchange them for gold.

"A lot? How many?"

"Isn't it according to the previous policy that [-]% of the gold and silver exchanged from Datang coins need to be kept in the household department?"

Dai Zhou said bitterly: "Go back to the prince, of course we dare not use this percentage."

"But this time, there are a total of 300 million Tang coins that came to be exchanged. The Ministry of Households really doesn't have so much money!"

Hearing this number, Li You was also surprised: "300 million, how could there be so many?"

"How many Tang coins have been exchanged now?"

Obviously, Dai Zhou had already done his homework before coming here. When Li You asked, he immediately replied: "Not counting the 200 million guan that I went to Shicheng to exchange this time, I exchanged a total of 460 million guan before!"

Speaking of which, it was the first time for Li Shimin to hear this number, and he was also very surprised by such a huge number.

"400 million guan! Is there really so much money?"

Obviously, Li Shimin was overwhelmed by this number.

Li You rolled his eyes at him impatiently and said: "Yes, father, the amount should be correct. Nearly 900 million of them were exchanged when the minister was still in the household department."

"In the past three years, in fact, it has only increased by 500 million."

"Most of the money has been used in road construction, farming and water conservancy in various places."

"In the past few years, Datang's annual tax increase is also due to these investments."

At this point, Li Shimin finally came to his senses.

Now Datang's annual tax has exceeded 300 million guan, a full increase of [-]% compared to three years ago.

Li Shimin was also overjoyed to achieve such an achievement under the circumstances of Datang's light taxation.

But now, Li Shimin finally understood how much work the household department had done behind such a huge increase.

Thinking of this sudden large amount of exchange, Li Shimin quickly asked: "Is there any problem with these Datang coins?"

Hearing this, Dai Zhou said hesitantly: "Actually, my first reaction was the same as your Majesty's, but after several inspection methods, we didn't find any problems."

"It is precisely because of this that the minister invited Mr. Wang to help us test the authenticity of these Great Tang coins."

Hearing Dai Zhou say that the authenticity cannot be checked, Li You also became serious, and asked, "Then have you checked the background of the person who came to exchange this time?"

"Sometimes, we can also see the problem from the person's background."

At this time, Fang Xuanling on the side said: "I have checked, and the people who came to exchange are not natives of Chang'an, to be precise, they are not citizens of Datang!"

"These exchanges were made by Persian merchants from the Western Regions. According to them, the money was obtained from their transactions in Datang over the past few years."

"Now they are preparing to return to Persia, so they are going to exchange the money into gold and silver and take it back at once."

Hearing this explanation, Li You also frowned.

The statements of these Persian businessmen are reasonable, and there seems to be no flaws.

But the more there is no flaw, the more Li You thinks there is a problem.

He said, "Dai Shangshu, have you accepted the money?"

Dai Zhou didn't quite understand what Li You meant, but he still shook his head and said, "Of course I didn't collect all of them. I used an excuse to verify the authenticity, so I only collected [-] coins for inspection."

Hearing this, Li You was finally relieved. Just now, he had already guessed the truth behind this matter to a close.

Li You said, "Dai Shangshu, you have done a good job. You can ask them to bring Datang coins to exchange in three days."

"There must be a problem with the source of this batch of Datang coins, but if we delay in exchanging them, I'm afraid Hou Junji will be in trouble when he sends them to Shicheng to exchange them for gold and silver."

"And this is what they most want to see. It is estimated that as long as there is any problem with our exchange, the news will resound throughout the Western Regions."

"After losing credit, it is even more difficult to promote Datang coins."

After Li You finished speaking, Li Shimin asked worriedly, "Your, are you sure you can raise so much money in three days?"

However, Li You smiled and said, "Money?"

"I won't give him money. Don't think that if you master the technology of Shence Mansion, you can really print Tang coins!"

"Most of these people's Tang coins must be fake. Let them exchange them in three days, just want to make a good layout and catch them all!"

Then Li You looked at Dai Zhou again and said, "However, to be on the safe side, after we go down, we should contact Chief Kang Jie to see if there is a shortage of Datang coins on the grassland."

"If nearly one-fifth of the Tang currency is really hoarded by these Persian merchants, then there will be a currency shortage on the grassland."

Dai Zhou quickly nodded in agreement.

Although Li You had already spoken, Li Shimin was still a little worried: "You'er, are you really all right?"

"If it's true, I can put it on for you from Neikuli first."

Hearing this, Li You looked at Li Shimin with a green light in his eyes.

[Li Er, your inner library is not bad! 】

[More than 100 million guan, you can take it out if you say it. 】

[It seems that in the past three years, you have really made a lot of money! 】

【Hmph, with so much money, you actually need to pay for the grandpa's palace repairs, so I don't want to find a way to drain your internal treasury! 】

Li You's greedy gaze made Li Shimin tremble, and he quickly said: "I can only pay for a part, and my internal treasury is not sufficient!"

"You'er, you have to take advantage of the limited few days to get this matter done. Even if it's fake, you must show sufficient evidence, and you can't let these Persian businessmen tarnish my Tang Dynasty's reputation!"

"My internal treasury, you'd better not think about it!"
