I was a village chief in a primitive society

Su Bai brought Hu Er Niang to the Scientific Research Department, ready to test the latest research products.

Since he became the shaman of the tribe, he has tried every means to improve the quality of life.

After all, the living environment in the primitive era was very harsh. Since the living environment cannot be changed, then the quality of life must be changed.

"witch!"Jue immediately greeted him.

He is the head of the Scientific Research Department, and he is over thirty years old. He can be regarded as an old man in the tribe.

"How are the curtains you developed?"Su Bai asked.

The curtains used in Yong'an Building are rewarded by the system. They are very good in shading and texture.

But it is not enough for him to use alone. Curtains are a necessity of life, and research and development is urgent.

Once the rainy season arrives, It will rain all the time and the light will definitely not be good.

If you open the windows, water vapor will drift in, and people will easily get sick. But if you close the windows, it will be very stuffy and there will be no air circulation at all.

It is the same in summer. Although it will be cooler if you open the window, you will also be tortured by direct sunlight, which will make the room even hotter. Although it is a good idea to use leaves to block the sun, there will be no wind blowing in at the same time, and the room will be very stuffy..At this time, curtains are the best regulator. As long as there are curtains in front of the windows, many problems can be solved.

"Wu, we are working hard on research and development, and we have developed several samples. Do you want to take a look?"Jue said respectfully

"Show it to me."Su Bai ordered.

The Scientific Research Department has been developing many new things since its establishment.

Of course, the research and development materials for these new things are all provided by Su Bai, otherwise people in the primitive era would not understand these.

"yes."Jue immediately asked his apprentice to bring over the curtain samples that he had made these days.

Since it is still being tested, the curtains will not be made directly, but only a rough sample.

Jue handed over several small curtain samples. He walked over and said respectfully:"Witch, look at what needs to be improved."

He was trying his best. Ever since he received the task of developing curtains, he has been busy with it.

Su Bai picked up a gray-brown curtain sample and it seemed that the size was just right in his hand.

He wrinkled as soon as he took it. Frowning, he asked,"Is this made of the same material as linen?"

The feel of this small curtain is so familiar, it's the same as the linen he just took over the development of the tribe.

"Yes, witch."Jue saw Su Bai frowning and starting to sweat, and immediately explained:"We wanted to try different things, so we also chose linen material to try it out."

He regrets it very much now. Not to mention how young Wu is, but the sense of majesty radiating from the inside out is really intimidating.

Not to mention that Wu is frowning now, he must be angry.

"It’s okay, linen curtains are a bit luxurious, and many people can’t afford to replace them with linen curtains."

Su Bai put down the curtain sample and continued:"As for other tribes, we cannot let them replace these curtains."

"Wu, isn’t this a product that can buy us a lot of things? Why not let other tribes switch? Yuying asked curiously

"Silly girl, curtains require a lot of materials. If we really use linen to make curtains, we will waste a lot of linen. Sha

Lan stood up and continued:"And after those people change back, they may not really use them as curtains. Doesn't this make those people cheaper?""

"It turns out that linen cannot be used as the raw material for curtains."Yu Ying said immediately

"I understand, I have written it all down, and I will continue to develop materials suitable for curtains."Jue immediately responded.

He felt relieved when he saw that Wu was not angry, but picked up the second curtain sample and started to look at it.

"The light transmittance of this material is good, but it is a bit hard and uncomfortable to hold in the hand. How can the wind still enter the room?"

Obviously, Su Bai was also dissatisfied with the second curtain sample. The texture was like the kind of socks that had been washed and dried casually. They were so hard that they could not move.

"Wu, we don’t think this part is suitable. It’s indeed too hard, and it might even hurt people."

Jue laughed awkwardly. When this curtain was developed, he also laughed at himself like this.

Su Bai didn't say anything, just nodded lightly, picked up the third curtain and started to look at it.

He nodded thoughtfully. Head, said:"Although this curtain is soft, it has poor light transmittance."

Su Bai held the curtain and looked at the top of his head for a long time, and found that it completely blocked the sunlight above.

"This is also our problem. With the lessons learned from the second piece, we just want to improve the softness. Who knows?......"He lowered his head in embarrassment.

Su Bai looked at the last curtain sample left. He picked it up and looked at it for a while before shaking his head and saying,"This piece is too heavy. It must have used a lot of materials, right?"

Curtains are not luxury goods, they are just a kind of luxury goods. Daily necessities are unnecessary if the materials and costs are too high.

People in primitive tribes now exchange labor value for food, items, etc. If the curtains require a high labor value when they are launched, I am afraid no one will be willing to exchange them.

"Yes, these curtains are not ideal. We are still in the process of research and development and will definitely combine these advantages to make them."Jue said immediately.

He was already sweating a lot, and he was quite nervous.

"You can try to find more materials in the forest. There are many plants in the forest, and you are not sure which plant fiber will be suitable." Su Bai reminded.

He didn't want the people in the Scientific Research Department to be too rigid. They should learn to use everything around them.

Instead of consuming the original things in the tribe all the time, it is even more important to innovate when there is no clue.

"Thank you Wu for the reminder. I will take people to the forest to start looking for materials later."It suddenly dawned on him.

He had always relied too much on witches, and for a moment he forgot about the forest that he had been relying on for survival.

It had fed generations of people, and many things in the tribe almost came from the forest.

"Pay more attention to plants with large leaves. If they feel light and flexible, you can bring them back and try them out."Su Bai warned.

The curtains of primitive tribes can only rely on plant fibers. Weave several of them together to see the effect.

Materials like nylon and polyester on the other side of the earth are not available here, so we can only use local materials.

"Got it, I wrote it all down."Jue said immediately.

The apprentices beside him also nodded repeatedly, thinking that listening to the witch's speech was really beneficial..........................................
