I was a village chief in a primitive society

Su Bai was obviously stunned for a moment, he didn't expect that Yu Ying, who was originally a bit reserved, would say this.

But then I laughed, and of course I was still in a good mood.

He smiled and shook his head, ate the remaining milk potato balls, and continued to think about what he had just thought.

"How to implement paper money in primitive tribes? This is a big project."Su Bai murmured to himself.

Yes, what he has always been troubled about is making banknotes in the primitive era. This is not an easy task.

Su Bai thought that it would be impossible to replace currency with labor value all the time. For him, bartering can only last for a while.

When the tribe develops better and better, bartering will become a bit out of date.

For example, if you have something of high value in the future, how much do you have to bring with you? Things can only be exchanged when they come.

What's more, in addition to replacing some better things, you also have to exchange some necessities back. In this way, you have to bring a lot of things out of the tribe.

You can't let a tribe of people go out. Should most of the people go out? It would be better to live in the Yanlong tribe, but is this possible?

"In the primitive era, the biggest problem in reproducing paper money was technology and raw materials."

Su Bai kept frowning and said to himself:"There is another point that needs the most attention, and that is anti-counterfeiting technology."

It can't be too easy to make banknotes, right? Otherwise, everyone will imitate it, and there will be a lot of fake banknotes on the market.

This is a very fatal problem for the Yanlong tribe, so the first consideration is to prevent counterfeiting. Technology is done well

"Although most people in primitive tribes are simple-minded, it is difficult to guarantee that some are smart. If the anti-counterfeiting is not done well, it is only a matter of time before the production method is cracked."

Su Bai blinked his black eyes and kept tapping the wall of the cup with his index finger,"The materials should also be unexpected, as well as the coloring techniques........"

The material of the banknotes must be special, that is, the material must be unexpected, and the color must be strong enough to prevent it from fading in your hand.

When he thought of this, he began to wonder if there were any ready-made materials around him that could be used. After all, design comes from life.

"If we could have that kind of relatively tough plant and produce paper in the same way as papermaking, the paper would be particularly stiff and not easily damaged."

Su Bai took a quill pen to record and murmured:"This kind of tree has to have good water absorption, otherwise it will be difficult to color. I'm afraid it's not easy to find a plant that combines these two advantages."

He began to think about other things, that is, the templates of banknotes, such as one yuan, five yuan, ten yuan, etc. These templates must be different. That is, the patterns on each denomination of banknotes must be different. Different, the color also needs to be different. This is the best way to distinguish the denomination of banknotes.

"Why don't some copy it? The one-yuan banknotes are still green, the five-yuan banknotes are purple, and the ten-yuan banknotes are blue......."

Su Bai kept lowering his head while recording, frowning and said:"But this is not the most important problem. It is not difficult to choose the color of the banknotes. The difficult thing is how to get the color."

He shook his head and didn't want to think too much, and took out a new one. Start preparing the paper to draw the pattern of the banknotes.

Su Bai took out another pencil from the drawer and started sharpening it. There were still many useless pencils in the row of pencils he took out last time.

After preparing the paper and pen, I also prepared a small piece of wood that was flat and smooth. It was similar to a ruler on the earth.

There are also some figures carved on it with a quill pen, which are some weights and measures data.

"The one-yuan note can be simpler. Just draw a forest on it, and then add a lake. The lake in the forest is very nice."

Su Bai bit the end of his pencil and thought, and continued to mutter to himself:"In addition, you can draw a totem of the Yanlong tribe as the main pattern, followed by some small patterns......."

Various patterns began to appear on the light yellow paper. In addition to the original pictures, there were also more numbers, such as the capital number one, Arabic numerals, etc.

These are all designed according to the banknotes from the other side of the earth. They must be exquisite and unprecedented.

"What pattern do you draw on the five-yuan drawing? Su Bai pondered for a moment, then raised his head and said,"How about drawing some totem warriors?" I think it should be possible."

Su Bai thought of this and began to continue painting by asking questions to himself. A lot of inspiration suddenly appeared in his mind.

"swish swish......."

Suddenly, the sound of pencils rubbing against paper came from the living room. Yong'an Building is usually very quiet, but the friction sound at this moment seemed very loud.

More than half an hour later, Yanjiao was summoned and came to Yong'an Building from the big market.

He lowered his head slightly and asked,"Witch, what are your plans?"

"I would like to know if there are any trees or plants that are very tough or have strong water absorption properties?"Su Bai asked curiously

"A resilient plant? There seems to be a kind of grass that our warriors use to bind the meat of ferocious beasts so that it can be easily brought back to the tribe. Yanjiao looked serious and continued:"As for what Wu said about good water absorption, I'm not sure what it means.""

"That's right. Since I haven't successfully made paper, how can I know whether it has good water absorbency or not?"Su Bai smiled self-deprecatingly and continued:"You ask people to find a few more tough plants, send them all to the papermaking workshop, and ask them to make paper according to the previous steps."

"Why did Wu suddenly want to use other materials to make paper? Is it because the previous paper didn’t work well?"Yanjiao doesn't know about the banknotes.

"You will know later that besides making more papers of different materials, I have other uses."

Su Bai then took out a notebook from the drawer, handed it over and continued to give instructions:"Besides, send some of various plants to the workshop. I want to see different types of paper."

He knew that not all plants could be used to make paper, so he had to experiment more. After all, there was nothing much to do during the rainy season.

"I understand, it’s just witchcraft......."Yanjiao kept looking at the notebook, touched it several times and asked:"Is this also paper? Why is it completely different from the paper made now?""

"What do you think of the quality and aspects of this paper? How does it compare with the current Wolf's tail paper?"Su Bai asked.

This notebook is just the sign-in reward given by the system some time ago. There are several more.

"Very good, very good. In terms of color, feel and toughness, it is much better than the paper we are using now. Yanjiao said without hesitation.

The color of the paper in this book is really attractive. The white flowers are very beautiful..........................................
