Daming: The system rejected my request for salted fish

The second is the carving technology. The patterns and texts on the banknotes are all hand-carved by masters.

There is also micro-carving technology, the complexity and sophistication of which are beyond the imagination of ordinary people.

In addition, the ink is also specially formulated, using red, blue and black colors for complex overprinting.

In addition, the treasure notes have various official seals of the imperial court, which contain hidden anti-counterfeiting marks.

The ink used for key official seals is also unique to the imperial court, and its production methods and raw materials are all under the control of the imperial court.

So after listening to Wei Wu's words, Zhu Yuanzhang immediately said with great certainty:

"No, in the seven years since the Baochao was introduced, there has never been a case of counterfeiting."

Then Wei Wu spread his hands and said:

"That's it, a silver note is simply a larger-denomination treasure note!"

After Wei Wu finished speaking, Zhu Yuanzhang pondered for a while, then shook his head and said:

"That's different. The largest denomination of Baochao is only one guan, which is one tael of silver. Counterfeiting is not only troublesome but also very risky."

"As you said, silver bills are used for settlements between merchants, so the maximum denomination is probably five hundred taels or even one thousand taels."

"If one forged document can be exchanged for a thousand taels of silver, there will surely be daring people who will take the risk, and the consequences will be endless."

After Wei Wu's previous explanation, Zhu Yuanzhang had a basic understanding of economic issues.

But precisely because of this understanding, one will be more cautious. After all, the face value of one thousand taels of silver is too large.

He couldn't imagine how serious the consequences would be if it was forged and printed on a large scale.

A single tael of Baochao could cause such a huge hidden danger, let alone a silver note of one thousand taels.

In fact, Wei Wu also understood that there is no perfect anti-counterfeiting method in this world.

Even the high-tech anti-counterfeiting measures of later generations are still being cracked by criminals who make counterfeit money.

But the emergence of silver bills was inevitable. If you want to develop the economy, you must get money flowing.

The trading behavior of merchants is the key to making money flow.

Fortunately, if it is an anti-counterfeiting measure, he happens to have an anti-counterfeiting measure that is absolutely impossible to crack in this era.

So after Zhu Yuanzhang finished speaking, Wei Wu immediately responded.

"Uncle Zhu, I know what you're worried about, but we can't give up on it just because it's risky."

"Regarding the issue of banknotes, we can improve anti-counterfeiting measures and update them every five or ten years."

"This will greatly reduce the risk, and compared with the benefits of silver bills, these risks are completely worth taking."

"The most important thing is that I have the anti-counterfeiting measures for banknotes, and I guarantee that no one can crack them and forge a fake."

After saying this, without waiting for Zhu Yuanzhang to ask, Wei Wu simply flipped his wrist and took out an iron bucket from the system space.

Zhu Yuanzhang and Zhu Biao looked carefully and saw strange patterns and incomprehensible words printed on the iron barrel.

As the two of them watched, Wei Wu casually placed the bucket on the table and then spoke:

"This thing is called color-changing ink. As long as we have it, no one in the world can forge our banknotes."

In fact, when Wei Wu first received this from the express delivery, his first reaction was to print money.

After all, the phrase 'I'll handle the color-changing ink' is so famous.

However, this fame was only for Wei Wu. For Zhu Yuanzhang and Zhu Biao, they had never heard of it.

However, based on the literal meaning, we can probably guess what it is.

So after Wei Wu finished speaking, Zhu Yuanzhang immediately raised questions.

"Color-changing ink? Xiao Wu, do you mean this ink can change color at will?"

"No, but it's almost the same. I'll show you the details and you'll understand."
