I was a village chief in a primitive society

Yanjiao came to Yong'an Building with broad steps, carrying an animal skin bag in one hand.

After getting permission, he walked into the living room and reported:"Witch, there is a strange thing"

"weird stuff?"Su Bai's thick black eyebrows raised

"This is it. We can’t even tell what it is. Will Wu know it after taking a look?" Yanjiao handed over the animal skin bag.

When he saw the contents of the animal skin bag, he was a little confused at first. After studying it for a long time, he still couldn't find a reason, so he thought of showing it to Wu.I think that there are many things that witches know, and there are many ideas in my mind. I will definitely know what these things are.

"Where did this come from?"Su Bai slowly opened the animal hide strap and looked at the things inside.

"It was Xiguo who asked the soldiers to bring it back, saying that they found it on the way to build the road and it was left from a tree. Yanjiao said

"Coming down from the tree, there is nothing but resin."Su Bai speculated.

He looked at the dark black liquid and couldn't explain why. On the other side of the earth, these things are usually asphalt or some black numerical values.

Of course, this was also the beginning. Hearing that these things flowed from trees, he had the preconceived notion. But after studying it carefully for a while, he found that it was not just resin.

Because the smell was particularly familiar. , there is an indescribable feeling of familiarity, but I don’t know what it is.

"Wu, you better not get too close, be careful this thing is poisonous. Yanjiao said worriedly.

When he took the thing and inspected it, he didn't dare to get too close because he was afraid that the gas emitted by the thing would be poisonous.

And he didn't dare to touch the liquid directly with his hands. He also took a few Poke with a small stick to see

"This thing is not poisonous, it's just that this thing is a bit familiar."Su Bai frowned and said

"How does the witch know that this thing is not poisonous? Does Wu know this thing? Yanjiao asked curiously

"If this thing was poisonous, this animal skin bag would have been corroded long ago."

Su Bai weighed the bag and continued:"And there are many people who have handled this liquid. If something really happened, those people should have been in trouble long ago."

What's more, the smell of this thing feels very familiar to him, as if he has smelled it somewhere on the earth.

"Wu, what is this? If it doesn't work, have them get rid of it all."Yanjiao said in confusion.

He felt very strange when looking at these things. He always felt that these things seemed to be of no benefit. He wanted the soldiers to get rid of these things quickly to prevent the dark black liquid from flowing out from contamination. The newly paved road

"No, these things might actually come in handy."Su Bai raised his hand and said.

He really felt that these things looked familiar, but he didn't dare to make a conclusion easily. He wanted to study it again.

"Wu, can this thing still come in handy?" Yan Jiao looked at the dark black thing with a bit of disgust.

Su Bai looked at the thick liquid for a while. The more he looked at it, the more his brows relaxed, and a smile slowly began to appear on his face.

He raised his head happily and said in surprise:"Isn't this just rubber? This is a good thing."

No wonder he always feels that this thing is very familiar, and there is always an indescribable feeling.

It turns out that this thing is rubber from the other side of the earth, and it is even worse.

"rubber? Wu, what is rubber?" Yanjiao asked curiously. This was the first time he heard this unfamiliar word, and he was very puzzled when he saw Wu's excited expression.

It seemed that this black thing was really useful, but he couldn't see how it was useful. Okay.

Could it be that this thing can be eaten? Or maybe it can heal injuries? In short, Yanjiao doesn’t understand.

"This thing is called rubber, and it can be of great use, especially in the development of tribes. This thing can be of great help."The corner of Su Bai's mouth raised in a nice arc.

There are many things that rubber can do, such as rubber shoes, rubber tires, rubber shock absorbers, etc.

This thing can also play a big role in the development of the tribe. With the strength, Su Bai had wanted this thing for a long time.

People thought that after a while they would ask people to go to the forest to find rubber trees or rubber grass, but they didn't expect that now it was delivered to their door.

"Wu, can this thing really help the development of the tribe?"Yanjiao can't believe it.

This thing looks dark, and it's really hard to imagine linking it to the development of the tribe.

"Of course, you will know later. Are there many of these things in the forest?"Su Bai asked.

He had just carefully studied the black rubber in the animal skin bag and found that the concentration of this rubber was particularly pure.

There are two types of rubber on Earth, one is natural rubber and the other is synthetic rubber..Synthetic rubber is naturally artificial rubber, and natural rubber is rubber that is extracted from rubber trees and then processed.

"I don’t know about this yet, I haven’t heard them talk about it. Yanjiao shook his head.

"Let them see if there are many of these things in the forest. If there are many, let them bring back some more."Su Bai ordered.

He was already thinking about how to prepare rubber boots, as long as there are enough raw materials.

This thing has come in time. If it is made quickly, this thing can be of great help in the rainy season.

"yes."Yanjiao turned around and left.

"Tap tap tap......"

An hour later, Xiguo received the order and hurried back to the Yanlong tribe, and came to Yong'an Building to report on his work.

He stood very straight, with a very excited expression on his face, and he did not expect that this thing would be useful.

I thought to myself that it was indeed right to report to the witch. As expected, the witch’s knowledge was countless times better than others.

"Wu, you said it.......rubber.......Trees are everywhere near the forest."Xiguo said quickly

"That’s a lot, right? It's really great."Su Bai said with suppressed excitement.

It would be nice to know that the quantity is large, so that you don't have to worry about not having enough raw materials.

"Wu, the soldiers have begun to collect the water flowing out of these trees........rubber."Xiguo is still very unfamiliar with this vocabulary.

"Well, let’s get a batch back temporarily, don’t make too many at once." Su Bai warned.

He wanted to get a batch first and come back for an experiment to see if the experiment can be successful. If the experiment is successful, he would not be in a hurry to get more.

Anyway, he is the only one who knows the purpose of this thing, and others don't. What can this be used for?

"clear."Xi Guo responded..........................................
