I am the cook, but I am Li Er's son-in-law

"As for the material of the joint, I have some clues. It's cheap, practical and durable." Yin Xuan rubbed Chang Sun's head again, "I'll try to see if I can get it out."

The little girls didn't doubt that he was there, and they all nodded in agreement.

The material Yin Xuan mentioned is rubber.

Yin Xuan has been thinking about this matter since he made the bicycle.

There is nothing that can be done about the rubber tree. That thing is now rooted in America, and it is impossible to expect an oak tree to float to the land of China alive and fall into the hands of Yin Xuan.

But... Rubber trees are not the only thing that extracts rubber.

Rubber tree, rubber grass, guayule, these three plants can extract natural rubber.Of course... the remaining two are naturally incomparable with rubber trees.

The rubber tree collects the glue, a knife, a bucket, cut on the bark, and wait for the white glue to flow out of the tree bit by bit.

However, things like rubber grass and guayule do not contain much colloid, only a few percent or less.

How much is it...Yin Xuan forgot.

Thinking of this, Yin Xuan clasped his hands together, thanking the Almighty ex-girlfriends, Wuliang Tianzun.

There is no need to think about guayule, this thing is also born in the American continent.

But... rubber grass can be considered.

To put it bluntly, rubber grass is actually a dandelion. When you go out to play, you will come across a dandelion. It is a small white tuft of pompoms. When you pick it up, the white juice that comes out is the glue that can extract rubber.

However...most plants of the dandelion genus cannot be used as raw materials, and they still have to be subdivided into rubber grass.

This kind of plant is now widely distributed in Tubo territory.

Tubo...

Let Linlang Pavilion put up a sign to collect it, and you can also hang one at the door of the restaurant.

Tubo merchants recently got a piece of news.

The county magistrate was collecting something called "rubber grass", and he didn't need hay, but the kind that could survive and grow, and he charged a high price.

A rubber grass was offered at a high price of five cents.

good guy...

If you get a car here, can't you get rich?
The Tubo merchants became excited, not only because they encountered an opportunity to make a fortune, but more importantly, this was an opportunity to connect with Yin Xianbo.

Maybe there will be a chance to have a meal at Tongfu restaurant.

That's the gourmet food of Tongfu Restaurant...

Unless they go all the way to Kucha and Gaochang, they won't be able to eat even a bite in this city of Chang'an.

However... there is an upper limit to this quantity, Yin Xuan only needs [-] plants.

Tubo merchants, as well as people from other countries, are busy now, and they all want to be the first to return to Chang'an City and deliver the ten thousand rubber grasses to Yin Xuan.

What is rubber grass...

They don't know very well, and there is no such thing in medical books.

However, Yin Xuan has a sticker to draw it. The leaves are like Persian vegetables, with long stems emerging one by one, which is also very recognizable among the weeds.

Yin Xuan didn't know whether this kind of grass would grow in winter, but anyway, it was these merchants who were in trouble, and I hope they have some skills to find this thing.

Chinese New Year is approaching.

It's just been a month or so.

A man wrapped in a black padded jacket with plateau red face appeared at the door of Tongfu restaurant, followed by a carriage pulling goods.

But he just stood at the door, looking into the restaurant on tiptoe from time to time, but he didn't dare to go in.

Zhao Yue looked at him for a long time, making sure that there was no danger, and seeing Li Yuan still playing mahjong, he relaxed his nervous mind and walked towards the man who obviously did not look like a Central Plains man.

"I saw you wandering around the entrance of the restaurant for a long time, what's the matter here?" Zhao Yue walked over and asked.

The Tubo man scratched his head and said, "The county uncle Yin of the Tang Dynasty said he wanted to buy rubber grass. I brought a batch here. They are all alive and can be planted!"

Zhao Yue nodded, and didn't intend to welcome him in, but just ordered: "Then you wait here, and I will invite the shopkeeper over."

He went in to report, and Yin Xuan came out after a while.

"Where's the grass?" Yin Xuan's eyes widened.

Tubo merchants greeted him: "It's in the car."

As he spoke, he called the men around him to remove the box from the carriage, and opened the box as he spoke: "I'm afraid that these things will die on the road, so the villain deliberately put all the dirt in And dug it up."

Inside the box was a square of earth, covered with a layer of grass.

Yin Xuan picked up one, shook off the soil, revealing the intact root system, and pinched off one of the stems, and the milky white juice soaked out.

Plants in the dandelion family are very recognizable.

Yin Xuan was sure that this was what he wanted, nodded in satisfaction, and directed to Jiu'er who followed him out, "Go and call some people to come over and take an inventory of things."

"Remember, as long as it is alive, not dead, especially the root system, and don't be careful not to let other similar weeds fish in troubled waters."

Jiu'er nodded, and trotted towards Huaizhen Square.

Yin Xuan glanced at the uneasy Tubo merchants again, and waved his hand: "It's okay to wait outside, if you're hungry, then come in and have a meal."

After speaking, he went straight in.

But the Tubo merchants and those guys hired by him still dare not move.

Zhao Yue said softly: "Since the shopkeeper said so, if you want to, just go in and eat."

"But it can only be you."

The Tubo merchant nodded again and again, took a deep breath, and bravely walked in. With Zhao Yue's assistance, he ordered a portion of Damo Fengshali and Huoyanshan.

In addition, there are two bowls of rice and a corn.

Of course it's not free food, you still have to hand over the money obediently.

The other diners in the restaurant frowned, without hiding it, and said bluntly: "Why did you put Fanzi in?"

Datang is a very inclusive country, but it is also a very exclusive country.

We can do business, and you can call me big brother, but if you want to be my family, this is not acceptable.What's mine is mine, and what's yours...is also mine. I just borrow it from you for the time being. One day, you have to give me back what I want.

Tongfu Restaurant is in Chang'an, it is like a "sacred place".

Datang people come in to eat, regardless of origin.

But those are also Datang people. In their hearts, whether it is Tubo or Turks, when will these people be compared with Datang people?

Zhao Yue explained: "He brought the rubber grass, which is a very important item for the shopkeeper. If it is what it is, half of it will depend on this thing."

"That's why the shopkeeper allowed him to come in for a meal."

On "once" he bites extremely clearly.

Only then did the other guests reluctantly nodded their heads, and made great contributions to the shopkeeper. This reason is acceptable.
