I was a village chief in a primitive society

Just as the paper was stuffed into the animal skin by Coco, what appeared in front of her was a piece of paper with a light green color.

This scene is exactly what the blonde girl expected. The paper made of fluorescent grass will glow in the dark.

"This is so amazing. I didn’t expect paper made of fluorescent grass to glow. This is the first time I’ve seen it."Keke was very shocked.

She had never heard of fluorescent grass before. She only heard a rough description from the person who sent the paper.

I heard that this kind of grass is like a predator and emits a little bit of fluorescence. To attract some flying insects and the like.

When mosquitoes land on them, the vines in the middle will stretch out to capture the prey, and then stuff it into the mouthparts near the roots for a feast.

Yes, such a nice name, And it sounds indifferent to the world, just like the piranha, it is a carnivorous plant.

"If this could be made into banknotes, would it be able to have a natural anti-counterfeiting mark?"Coco murmured to herself.

She pulled off the animal skin covering her head and returned to her position thoughtfully.

First she poured herself a glass of water, and then she fell into thinking.

Of course, She didn't stop when she was thinking, but she was doing experiments.

She poured water on the paper, but the paper was soaked in an instant, and it would rot when touched.

The whole process only took more than ten seconds. , the blonde girl was completely confused by this scene.

"The quality is really average. Although this may be developed as an anti-counterfeiting feature on banknotes, it is too intolerant to moisture. Coco looked at the mess of paper on the table with disgust and muttered:"I'm afraid it will rot in the middle of painting, right?""

The blond girl picked up the fourth type of paper. The raw material of this paper is more common, which is the hollow tree.

This is the hollow tree that is now used as a water pipe by the Yanlong tribe. It is relatively common and easy to obtain.

In the Li tribe, it is not Far away, there is a large hollow forest, which can be said to be inexhaustible.

"The color of the paper is quite good, rather white. Wu said that white paper is better paper, and it can be exchanged for many things."

Coco murmured to herself while shaking the paper, wanting to test the flexibility and the sound it produced.

Because Su Bai told her that good paper is shaking when , is not easy to crack, and does not allow for wrinkles.

The most important thing is that the sound when shaking is quite pleasant, and the tones emitted by many papers are different.

To this end, Keke has also experimented a lot This time, even if the first three types of paper are shaken, they all make different sounds.

The first kind of paper made from red knot trees makes a softer sound when shaken, that is, the sound is not the same. It doesn't sound very good.

When it is shaken, it is easy to wrinkle, but it does not have any cracks.

The second kind of paper made of stone thorn tree has a harder sound when it is shaken. It is said to be unpleasant, just like It's like the sound made by steel plates.

It's dull and heavy, and the overall tone can be said to be the worst among the four types of paper.

But it still has advantages, that is, when shaking, the paper does not wrinkle. Cracking and other phenomena.

No matter how you shake the paper, it will appear as it is, that is, there are some wrinkles where you hold it.

Of course, you cannot directly knead the paper. No matter what kind of paper, you can do it like this If you rub it, it will wrinkle into a ball.

The third kind of paper is not so good. When you shake it, the whole paper will crack.

Not to mention wrinkles, the whole paper will no longer exist. In fact, The property is a bit stretched.

Now it is the fourth type of paper. When shaking, the sound is the best.

But there is also a disadvantage, that is, wrinkles are easy to form, and when they are formed, they are very frizzy, and there are some in the wrinkles. fine hair

"Sure enough, there is no perfect paper. Each type of paper has its own advantages, but it also has various shortcomings."

Coco put down the paper with a slight disappointment and continued:"It would be nice if the benefits of these pieces of paper could be mixed together and the disadvantages eliminated, but obviously, this is not realistic."

The blond girl sighed and looked at the several papers in front of her.

She didn't know how to start. She originally thought that no matter how good these papers were, one of them would always be good, right? But it turned out that one Not suitable for making banknotes

"Eh? No, I can ask the workshop to produce more different types of paper. Where is this? How could I give up so early?"

Coco immediately became energetic and continued to murmur to himself:"I think it's better to go to the workshop in person, so that I know what to do."

The blond girl doesn't want to stay in the laboratory anymore. She's on pins and needles.

It's better to go directly to the source to find out what's going on. Maybe this way she can get a clue faster.

"However, the papermaking workshop is relatively confidential, and it is one of the important workshops of the Yanlong tribe. I am afraid I will not be allowed in."

Coco instantly felt a little disappointed and muttered:"It would definitely be different if I could go in and have a look, but I can't make it difficult for the witch to do it."

The blonde girl thought of this and began to prepare for other experiments.

She wanted to see if it would be better to start from other places first, so there is no need to stick to the paper all the time.

"Wu said that banknotes must be colored, and they must not fade easily, and the colors must be difficult for others to imitate."

Coco frowned and murmured to herself, her slender fingers kept moving back and forth on the materials on the table.

For a moment, the blonde girl fell into a bottleneck and didn't know how to start.

This was all within her scope of cognition. I'm outside, so I don't know what to do in the first step or how to do it.

"Let’s first classify these materials that can be adjusted into colors, and then proceed to the next step."Coco cheered up again.

Her golden eyes scanned the materials on the table, and she began to take out wooden bowls one by one and sort the materials.

That is, the red paints were together, the yellow paints were together, and so on. It takes a long time to classify.

Because the materials on the table are also found by Yanjiao, various fruits, plants, stones, etc.

As long as they can produce color, most of them are It was placed on the table.

There were all the materials, and Su Bai seemed a little confused about where to start.

But if he wanted to really study it, it was not impossible, but he didn't have that much free time to spend on it.

In addition, the blond girl She likes experiments very much, so I just let her come here to give her some exercise.

"According to what Wu said, there is still a long way to go."

Coco rolled her eyes cutely, took a sip of water and started to devote herself to her work..........................................
