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

Tubo people are also very discerning, so they eat carefully.

He was afraid that he would make some noise and annoy the diners in the room, and then throw him out - among other things, he knew very well that he could not provoke any Tang people in this room.

Fortunately, Tang people regarded him as air and didn't pay much attention to him.

Jiu'er called You Xia'er and quickly counted them.

After the Tubo people carefully finished their meal, they ordered three taels of wine and drank it down, and finally counted the number.

There are 420 plants in total, and 72 live plants. The remaining 2000 plants are either dead or have incomplete root systems, so they are discarded.

The good product rate of more than 80.00% is considered very good at the moment.

The first 1000 plants were purchased according to the previously agreed price, and the next [-] Yinxuan plants were not wasted, and were purchased at the price of ten plants per penny.

The Tubo businessman was so happy that his face was wrinkled.

He buys locally, hires a child for a penny, and can dig hundreds of plants a day. The more than 1 yuan only took him nearly ten days and more than ten pennies.

When the remaining merchants came over, they were so angry that they learned that someone had already taken the first step.

but…

Yin Xuan wanted all the rubber grass they brought, but instead of the high price of five renminbi for one plant, he bought it for ten stalks for one renminbi.

A total of more than 50 plants were harvested, and by the way, there were more than 3 plants that were dead and "unusable" according to Yin Xuan's judgment.

The planting period of rubber grass is in March and April.

We have to wait until the spring of the next year. Yin Xuan asked You Xia to transplant them into the greenhouse so that they can take care of them. Yin Xuan's requirements are not high, at least...can't wait until the beginning of spring for all of them to die.

As for those that were dead and could not be replanted, they were regarded as Rao heads, and Yin Xuan begged them all—at least they were not completely dry, and they could still be used for experiments.

Efficient rubber production requires an industrial base.

Yin Xuan will not be able to get the chemical reagents he needs for a while, such as low-temperature buffer solution, acetone, etc., let alone magnetic extraction.

Therefore, we can only choose the most stupid method-dry grinding.

Firstly, the grass roots are ground, then artificially vibrated, and finally the rubber filaments and the surface of the root system are separated by air blowing.In this way, crude glue can be extracted.

Further purification is simpler, as long as the coarse rubber is soaked in hot water, wait for a period of time, and what floats to the surface is pure rubber.

only……

The amount of rubber extracted is very small.

These more than 3 trees were eventually extracted to about ten catties of rubber.

Follow the method one by one, and extracting the rubber is not difficult. After seven or eight days of tossing, it is also done.

It’s just that the efficiency is too low. There are more than 3 rubber grasses, about 1000 two hundred catties, but only ten catties of rubber can be produced in the end...

However, the difficulty is not in extracting rubber, but in processing rubber.

Without machines, it is very difficult to process rubber into the shape you want purely by hand.Moreover, this rubber extract has a certain shaping ability, but it is far behind those high-quality products in later generations.

High cost, long process and low quality.

But... let's make do with it, otherwise what else can we do?

Yin Xuan didn't rush to think about rubber processing, because... New Year is here.

It's another new year.

They even lived in Yin Xuan's house with Li Yingzi and Fang Yiyu. Of course, they lived in the guest room.Li Jing's mind is very stable, knowing his daughter's nature.

Fang Yiyu blocked from left to right, but he couldn't stop her.His wife also contributed to the flames by packing clothes and jewelry for Fang Yiyu, for fear that her daughter would just talk about it but actually refuse to live there.

Is there such a mother?
But he also knew that this was really a good thing for the Fang family.

Now that His Majesty is cleaning up the aristocratic family, his family Qinghe Fangshi will inevitably be hit, marrying Yin Xuan, among other things, at least his own branch will be able to live a prosperous life in the next three generations.

It's just... He really couldn't bear to part with such a daughter who looked like flesh in the palm of his hand.

Fang Xuanling and Li Jing had a lot of conflicts about whom to marry Yin Xuan for the second time now.Changsun Wuji's mentality is very peaceful, you can fight as you like, and he has no objection when his daughter is the last to marry.Although... the eldest grandson has been entangled for a long time, insinuating that he wants to get married.

This New Year is more lively than ever.

Although only one square city like Datong has become an industrial zone, a group of people have copper in their hands, and even other people are more or less stained with oil and water.

In Chang'an City, every household bought pork to buy pork, and some people even bought a mutton with a sling of copper coins.

Firecrackers are essential.

As soon as the New Year's Eve enters, the sound of crackling resounds throughout Chang'an City, and bright red cannon paper is flying all over the sky. Everyone must say congratulations and well-being when they meet.

Small citizens are more willing to say "get rich". They don't pay much attention to social status, or it is not the time to pay attention to it. They only think that it would be better if they can eat a few more pieces of meat next year than this year.

For Yin Xuan.

The biggest achievement in this New Year is "accidentally" eating two more fresh red apples.

Li Shu entangled tightly, and Yin Xuan took a bite.

The most courageous one was Li Yingzi, who had no sense of presence in the past, but on the night of the second day of junior high school, she planned an attack. Rather than saying that Yin Xuan bit the red apple, it was better to say that he was bitten by the red apple.Finally he bit back.

Li Lizhi shrank aside, not daring to speak.

after new year.

Li Shu still had to put on a show, but Li Yingzi had already put on a woman's hair bun.

Fang Xuanling's face turned green. Originally, he had the upper hand in the confrontation between him and Li Jing, but he never expected that he would be tricked by a little girl.

Of course... there was more than one reason for his face to turn green.

Li Yingzi is like this, what about her daughter?

Damn it, Yin Xuan is really quick and ruthless in his strikes.

He was about to drag Li Jing to drink some wine, but when he turned his head, Li Jing disappeared. He had already gone to the teahouse to discuss marriage with Wang.

His own daughter is like this, Fang Xuanling still has the nerve to fight with her?

If you have the ability, let your daughter also wear a woman's hair bun.

Yin Xuan has been busy with other things these days, and the scale of the textile factory will definitely expand in the new year. He asked people to do a survey, and farmers around Chang'an are very willing to plant cotton.

The bicycle factory should also reserve a piece of land.

Therefore, the location of the rubber factory couldn't fit in Datongfang. He bought some land in Da'anfang and planned to build the entire Da'anfang into a rubber factory.

Neither the Chang'an County Government nor the Jingzhao Mansion were hindered by Yin Xuan.

Bought without a hitch, built to spec.
