I was a village chief in a primitive society

The next morning, Coco went straight to the laboratory as soon as she woke up.

She couldn't wait and didn't want to waste any more time, if Su Bai hadn't forced her to have a good rest last night.

I'm afraid that Coco was already in the laboratory last night, so how could he wait until the next morning?

"It’s still that familiar laboratory, I miss it so much, I’m back again."

Coco felt a sense of intimacy when she opened the door, and her golden eyes kept scanning everything in the laboratory. The blonde girl felt so surprised. She didn't expect the witch to maintain the place so well, and her nose felt a little sore for a while.

Coco instantly felt more respect for Su Bai. This place was originally a temporary laboratory.

She originally thought that after leaving, it would become a room again, or else it would be used as a storage room or something like that. After all , there are many good things in the Yanlong Tribe. For safety and privacy, it is definitely better to keep them close by.

Yong'an Building is the best place, not to mention that the second floor is where Su Bai often works. It was natural for the laboratory to be converted into a storage room, but instead of being like this, it was kept intact.

For Coco who loves experiments very much, this is undoubtedly the best gift.

"I will definitely not disappoint Wu's expectations and develop banknotes no matter what."Coco instantly became more competitive with herself.

The blonde girl pulled out the stool and started straight away.

She began to sort the materials that the maids had brought in this morning. After sorting them, she began to think about what Su Bai had said to him yesterday.

That is, the texture, toughness, anti-counterfeiting, etc. of banknotes, all of which must be reflected on banknotes.

"It seems a bit difficult to achieve, but that doesn't dissuade me."Coco started to cheer herself up again.

The blonde girl took the lead in laying out the papers made of four kinds of plants. Her golden eyes were so close that she almost touched them.

"The first type of paper is paper made from red knot trees. The overall color is light pink and it feels softer to the touch."

Coco held the paper towards the window, letting in the outside light,"This kind of paper is not suitable, it will rot easily, let alone coloring, it will not last thirty days."

The blond girl carefully recorded the characteristics of the first type of paper, because she would report to Su Bai at that time. After she finished speaking, she picked up the second type of paper and began to look at it. The raw material of the second type of paper was the stone thorn tree.

The paper made from the thorn tree is gray in color and looks tough and indestructible.

"The texture of this kind of paper is very good, and the softness and hardness in the hand are just right, which matches the toughness Wu mentioned."

Coco thought thoughtfully, and continued to mutter to himself:"I just don't know how good the coloring is. I have to try this to know."

The blond girl immediately picked up the small cup next to her. The cup was filled with just boiled water.

Without any hesitation, Coco poured the water directly on the paper made of the stone thorn tree, but only poured a small area.

Then. Drops of water fall, and those water droplets float directly on the surface of the paper, looking like water drops on a lotus leaf.

"Does this count as a failure?"Keke raised her eyebrows slightly.

She had never thought that this would happen. Then she poured more water on it and found that the scene just now still appeared.

"The coloring is not good, even water cannot penetrate, so how can the color still adhere to the paper?"

Coco shook her head in disgust, and then put a whole piece of paper into the water cup, but she was still indifferent. It took a while for the paper to be soaked with water. The blond girl roughly calculated the time. From the paper into the water cup, it was completely The soaking time is about five minutes.

There is a small alarm clock next to Coco, which Su Bai gave to her specifically so that she can calculate the time more accurately.

Since the establishment of the laboratory, Su Bai has Because of her, the experimental time must be rigorous, and you can't mess around.

"I thought I had found a good piece of paper, but it had been soaked in water for too long. Wu said that it was probably not perfect."

Coco put the paper aside without hesitation and prepared for the experiment on the third type of paper.

For no other reason, when Su Bai taught her, she said that the coloring experiment can be tested with water.

Anyway, it's time to The coloring process also involves dipping the pigment into the paper, so it is simplest and crudest to test with water in the early stage.

The third type of paper raw material is more special, it is a raw material called fluorescent grass.

Fluorescent grass is not It’s hard to find, usually only found in caves.

Although fluorescent grass is hard to find, once you find it, there are a lot of them, because fluorescent grass appears in patches.

The function of fluorescent grass is just like the name , as the name suggests, it emits a faint fluorescent color, but the color is very weak. The overall color is like a firefly. If you don’t look carefully, you won’t know that this fluorescent grass is fluorescing. The

Yanjiao people are looking for materials to make When I was shopping for paper, I happened to find fluorescent grass, so I took it back together to see if it could be made into paper. The paper made from fluorescent grass is similar to the paper made from Pennisetum. They are both a little light yellow and not as bright. How to make it pure white and flawless

"The paper is too thin, and it looks like it will break if it is blown by the wind."Coco curled her lips.

The blonde girl put the paper on the table again. Just when she got up to pour herself some water, she discovered something different.

"Eh? There's a little bit of a shimmer, which is......"Coco made a sound in surprise.

She immediately adjusted her sitting position and picked up the paper to read, but when she just picked it up, the glimmer disappeared immediately.

"Ah? Is it my imagination? Why are you missing again?"Coco immediately turned the paper left and right.

She saw that the glimmer of light that had flashed by disappeared immediately, and the paper turned into the same appearance as usual.

Coco recalled her actions just now, as if she was getting up to pour the paper. Water.

Then she immediately looked out the window and saw the bright weather and dazzling sunshine outside.

Coco's mind was running rapidly and she was surprised:"Is it possible that there is light, so this little bit of light cannot be displayed?"

The blond girl thought of this, and immediately stood up and closed the window. She leaned against the window to block the sunlight.

Then she pulled a piece of animal skin to cover her head, and she put the paper into the animal skin with excitement.

She I want to use this to prove whether the paper will emit a faint light in the dark state..........................................
