Crossing Wu Dalang starts from selling cakes

Chapter 459 Fire and water are impenetrable!

Song Huizong was stunned: "Wu Aiqing why is this? These banknotes are exquisite in workmanship, wouldn't it be a waste to throw them in the water!"

Wu Zhi smiled and said: "Your Majesty, you will find out later, everyone, please take a look!"

While speaking, Wu Zhi's right hand pointed to the water surface of the copper basin full of water on the ground, and everyone's eyes also gathered.

The banknotes in the water are in a floating state. The paper after being stained with water does not sink in water like ordinary paper, and it shows signs of breaking when pulled.

Instead, Wu Zhi reached out to pick it up, and shook it twice in front of everyone. The water droplets on it actually spilled out one after another, and fell to the ground with a ticking sound.

It turned out that the water did not contaminate the banknotes at all, and it was in the form of a round bead attached to the surface. If you flicked it lightly or wiped it off, the water bead disappeared.

The paper money is still the original paper money, and there is no damage.

You must know that this is paper currency, but it has such an effect, which has greatly enhanced its preservation.

Song Huizong got up, came over curiously, held it in his hand, looked at it, stroked it, and found that it was clean and tidy, the color had not changed, there was no fading, and there was no water, and it was already dry.

This made Song Huizong look weird.

Guo Feiming next to him also took a look, including the other ministers who looked at it curiously.

They are almost unbelievable.

Song Huizong asked in surprise: "Wu Aiqing, why is this? Why don't the banknotes get wet?"

"Yeah, it's strange!"

"It's just an anecdote. I've never seen this kind of paper. It's incredible!"

The courtiers also mobilized their curiosity.

At this time, Wu Zhi smiled and said: "Your Majesty, it's actually very simple, because when I made this banknote, I processed some details and sealed a layer of wax on both sides of the banknote.

This kind of wax has been processed in several layers in the production of paper. After chemical action, it is slightly baked with fire to attach it, so that there is waterproof wax on the banknotes.

And the paper is not one layer, but several thin layers inside, basically all of them have been treated in this way.Even if the banknotes are soaked in water for many days, the color, pattern and structure will not be damaged. Even if there is damage, the amount can still be identified. If the people suffer from floods, the money can still be exchanged at the Dasong Bank New banknotes, so the problem of blisters is basically solved. "

Wu Zhi's words made the expressions of all civil and military officials present change again and again.

They have never heard of such a technology.

How can a banknote do this?

Before Wu Zhi finished speaking, he continued: "Not only is it waterproof, but the wax layer of this banknote can be preserved for a long time!"

"Six months, or a year?" Guo Feiming asked immediately.

Wu Zhi shook his head.

"Can it be preserved for more than two years?"

Wu Zhi said: "If there are only a few years, the waterproof effect is unnecessary. The waterproof wax layer of banknotes made by the truth can be preserved for at least 100 years!"

s...

Everyone took a deep breath.

It's hard to imagine a piece of paper kept for such a long time.

This is just paper, not metal. If it can be kept waterproof for such a long time, it can indeed solve the impact of water damage on banknotes.

The common people are also assured of using it.

Wu Zhi smiled and said: "This wax layer is made of a natural mineral, and it cannot be melted away in 100 years, so the waterproof effect is excellent. The waterproof problem that the adults questioned before has been solved now."

Guo Feiming: "Mr. Wu, how can you guarantee that the banknotes will be waterproof for so many years? The banknotes have just been made, and they haven't been used for such a long time, so they don't know the effect at all."

Yup!

It hasn't been used for such a long time, how do you know it has this effect?

Isn't this an obvious loophole?
Is it Wu Zhi's nonsense?
Wu Zhi: "Master Guo doesn't need to question this. This kind of wax layer has been recognized by professionals for such a long time, and it has nothing to do with banknotes. Master Guo, if you don't understand some things, you will inevitably be ignorant. If you don't believe me, you can find someone who specializes in this area It will be clear for experts to understand!

The main research and development of our banknote factory is how to integrate paraffin into banknotes. As for things like paraffin, they have already passed the test and are not released just now. "

At this moment, a courtier said: "What Prime Minister Wu said just now, the effect of paraffin wax is indeed true. There is a fellow in the lower official who makes this kind of thing, and it can indeed be preserved for a long time!"

The minister said a fair word and popularized some common sense to others, so that Guo Feiming, who didn't know professional knowledge, immediately shut up.

Of course, paraffin wax can evaporate after a long time in a high temperature state, but in ancient times such a climate reached [-] degrees, not many, so it can actually be stored for a longer period of time.

What Wu Zhi said was just a conservative estimate.

Song Huizong had a wonderful expression on his face, and thought this banknote was really interesting.

Guo Feiming said again at this time: "Since waterproofing has such an effect, then it's fireproof!"

Yup!

What about fire protection?
Wu Zhi smiled and said: "Since it can be waterproof, it can also prevent fire! Please see!"

While Wu Zhi was speaking, he threw the banknotes in his hand directly into the brazier.

At this moment there is a flame burning in the brazier.

Throwing it in, some flames sputtered out, everyone held their breath, especially Zhao Heng, Guo Feiming, Wang Wei and others stared at the brazier.

If they are shocked by the waterproofness of banknotes, then it is absolutely impossible for them to be waterproof.

Because water and fire deal with paper money, it is definitely the flame that occupies the absolute destructive power.

That is, metal can be turned into a puddle of water under the burning of the flame. Can the banknotes withstand the burning of the flame?
After about a minute, everyone felt that the banknotes should have been burned.

There was charcoal fire inside, and Guo Feiming was still a little surprised, expecting Wu Zhi to make a fool of himself.

With such flames, not to mention banknotes, even wood has long been turned into carbon.

Wu Zhi, Wu Zhi, let me see how you end up this time!

However, thinking that it is impossible for a dignified military minister to do such a stupid thing, he must have tried it before, so he took it out to do it.

After reading this, Guo Feiming became nervous again.

At this moment, Wu Zhi stretched out his hand and quickly took out the banknotes, which were still hot.

When I took it out, the banknotes were a little black.

Guo Feiming was overjoyed, if it is burned like this, it will most likely be impossible to use, that is to say, it is basically abolished.

Then Wu Zhi wiped it with his hands. Miraculously, after the layer of black carbon ash on the surface of the banknote was wiped off, the clean and new color of the banknote reappeared in the eyes of everyone.

Even the head portrait of Taizu is still vivid in the upper right corner of the banknotes, and it is well preserved.

This……

Guo Feiming: "Are you all right?"

Zhao Heng looked suspiciously, how did this happen?

"This is really a strange thing! The banknotes are impenetrable by water and fire. Could it be that someone has cast some spell on the banknotes?"

Many ministers sighed.

Wu Zhi said with a smile: "Spells? How can there be any spells? If I knew spells, wouldn't the Song Dynasty have already leveled the world and become the only big country!"
