Chapter 205 Rubber
On the side of the pottery basin, there is a totem composed of a pictographic "Tao" character and a pictographic "Tang" character.

Tao Tang clan?

Li Yan was taken aback, put down the pot quickly, and asked, "Patriarch Nanmang, where did your pottery come from?"

The Nanmang patriarch replied with a smile: "It was exchanged with a tribe in your surnamed alliance, called the Taotang tribe. That tribe comes once a year and exchanges a lot of goods with us every time."

"Tao Tang Tribe?" Li Yan thought for a while and asked, "Clan Chief Nanmang, how much is this pot worth?"

Nan Mang patriarch said: "A woman and a man!"

At this time, Qiao on the opposite side also said: "Our area is short of mud for making pottery, we can't make pottery, and none of us know how to make pottery, and there are very few tribes here. The Taotang tribe is a very good tribe. They come to trade with us every time with a lot of goods.”

Then, Joe took out another piece of yellow dry mud, and continued: "The sulfur we used was brought to us by the Taotang tribe. This scoop of sulfur only needs a piece of animal skin. The Taotang tribe also said that this Brimstone is worth two hides outside, but they only need one hide when they sell it to us, they are so kind!"

When Li Yan heard this, he blushed immediately, thinking, that Taotang tribe is too bad, 30 yuan of animal skins can be exchanged for a big basket of sulfur!

Li Yan rolled his eyes, and quickly took out two clay pots and a catty of sulfur from the gemstone.

This person from the Mu League was not surprised that he had a prismatic gemstone, but they were extremely surprised when Li Yan took out the "precious" goods such as clay pots and sulfur.

Li Yan said truthfully: "Guys, in fact, these pottery and sulfur are not worth so much outside. For example, a piece of animal skin can be exchanged for so much sulfur from me."

"What? Can a piece of animal skin be exchanged for so much?"

"Didn't the Taotang tribe say that sulfur is very precious? And that pottery too?"

When everyone heard this, they were all surprised, and some even showed anger. The Taotang tribe traded away many men and women, as well as a large amount of raw materials such as animal skins and horns, from the Mu surname alliance every year!
"Patriarch Yan, are you lying to us?" Youmu still couldn't believe it.

"How could I lie to you? You give me a piece of crocodile skin and this pile of sulfur, you take it away!" Li Yan said, "You give me thirty animal skins for this clay pot, take it away too!"

Not to mention, the suspicious person surnamed Mu really brought the animal skin and exchanged the goods that Li Yan put next to him. He still looked at Li Yan's expression when he took it, but Li Yan never showed dissatisfaction Abandon.

Patriarch Nanmang thought for a while, and then asked: "Patriarch Yan, our area lacks clay, sulfur, and obsidian. Look, we don't even have many pottery here to greet you. You Jiang tribe can make pottery, right?"

The current pottery industry of the Jiang Tribe is on the rise. It can produce thousands of pieces of pottery a year, and the output is still increasing. They are worried that there is no place to digest it.

This was exactly what Li Yan wanted, so Li Yan replied: "Patriarch Nanmang, our Jiang tribe has a lot of pottery and a lot of sulfur, I am happy to exchange pottery and sulfur with you, but obsidian, I can't help it. "

"Hehe, no problem, no problem!" Nan Mang patriarch suddenly smiled.

This Nanmang tribe is close to the swamp and is rich in animal skins. This is what the Jiang tribe needs. In the future, the raw materials of the Jiangnan leather factory can be imported from here.

Li Yan looked around the city, thought for a while, and said, "Nanmang patriarch, our Jiang tribe needs animal skins, and your sorcerer's tool called the guide stone."

"Guide stone? This is no problem, it's not a big deal!" Nan Mang patriarch said politely, the materials for making guide stone are not difficult to find.

Continue to eat.

The food of this Nanmang tribe is very rich, the barbecue is delicious, the grilled fish is also good, and all kinds of fruits are very delicious. For example, there are yellow fruits like donuts that attract Li Yan's attention. Li Yan peels off the yellow skin As soon as I ate it, it turned out to be a banana. However, there are many seeds in this banana, and the shape is a circle. It is probably the ancestor of bananas.

However, what made Li Yan even more excited was that he also found several sweet potatoes.

These sweet potatoes are only the size of a fist, and taste crisp and sweet. Sweet potatoes are a good species and a high-yield crop.

Li Yan told the patriarch of Nanmang that he wanted some sweet potatoes, and the patriarch of Nanmang readily agreed.

Li Yan thought for a while, and then asked, "Clan Chief Nanmang, do you have any special products here?"

"A special product?"

Patriarch Nanmang thought for a while, and ordered someone to find a gray-black basket.

The surface of this basket was covered with a layer of black mud, and it was filled with water.

"We still have this kind of tree mud! This is a container made of tree mud and baskets. It can hold water, but it can't be used for cooking. The Taotang tribe has changed a lot here!"

"Oh?"

Li Yan took the gray-black tree mud basket. When he touched it, he felt that it was soft and elastic, and the surface was a little hard. It felt like touching a football with water in it.

Li Yan touched it, looked at it for a while, and thought of the tree sap collected by this tribe when he came in before.

He suddenly realized that this is rubber, natural rubber. The ancient Indians used natural rubber to make many tools. Natural rubber is the most widely used industrial raw material. Moreover, adding sulfur to natural rubber can cause vulcanization reaction, making various kinds of tools. Various types of rubber products!
Although natural rubber can be used, its stability is poor, it will melt when preheated, and it cannot be exposed to sunlight. However, the properties of rubber after adding sulfur ratio will change qualitatively. It can be made into car tires and rubber. Bottom shoes!
However, at present, this kind of rubber is best made into a rubber bucket, just like the rubber basin in front of you, which is used to hold water. The rubber bucket is light, durable, and easy to make. It is very useful for watering or transporting water. , It is more real than a complicated tool like a wooden barrel!
Li Yan was overjoyed, smiled, and said hastily: "Patriarch Nanmang, I want to exchange this kind of rubber with you, which is tree sap. How many trees of this kind do you have?"

There is a lack of pottery in the swamp area. The tribes of the Mu Alliance all use natural rubber to make buckets, but this bucket cannot be dried in the sun, and it must be kept away from fire sources. The temperature in the storage place should not be too high. It cannot be compared with pottery.

Li Yan promised to give them pottery in exchange, and now that Li Yan is still interested in these rubbers, the Nanmang patriarch is naturally happy to come in time.

"Patriarch Yan, there are a lot of these rubber trees in our area. If you want, I can exchange them all for you, but you have to exchange them with us in pottery."

"This is no problem." Li Yan was overjoyed.

Just when everyone was chatting happily, a beast-skinned man ran in.

"Great chief, people from the Taotang tribe are here!"
