County Magistrate Du Xin stood in front of the peeling machine and observed. Sometimes, the shell would enter the kernel.
He squatted down and picked up an acorn kernel. He licked it with his tongue and smiled bitterly.
Pure wild acorns were like this. After soaking them in water for a long time, the tannins would be soaked out.
The commoners had a large number of acorns at home. They were afraid that there would not be enough food.
Before Du Xin became the County Magistrate, more than 90% of the commoners had plenty of time to eat acorn noodles every year.
They ate bitterly and did not have the time to soak the acorns. In addition, peeling the shells was tiring and delayed their work time.
"If you want to get rid of the bitterness quickly, it is best to use bamboo and tree branches to weave baskets in the river. In winter … … our river is not frozen. Try to be safe."
Li Yi pulled Princess Yongmu over to take a look.
If they used a large pond to soak the kernels, the tannins in the pond would be high and the shells would be soaked.
This was the stupidest method but also the most economical and labor-saving method.
"Now, it is mainly used for tanning leather. It is produced locally and sold in Chang 'an.
Li Family Zhuangzi's newspaper can help us advertise for free in small areas. It can be considered as helping the poor.
As for the price, you can consider it yourselves. If you think it is worth it, then it is fine.
Another use is to dig wells. It is easier to use tannin extract. "
When Li Yi said the words' helping the poor ', he suddenly remembered that Luo Nan was once a poor county.
At that time, the traffic was a few hundred times better than now, but it was still poor. One could imagine how difficult it was for the commoners now.
"Li Dongzhu, we don't know the price. Tell us what to do. We will listen to you and sell it to you."
Some commoners took over Li Yi's words and pushed the problem to Li Yi.
"Big Head Shi, are you crazy? You are asking Li Dongzhu for money. No, we will sell it ourselves. "Someone immediately rebuked the person who spoke.
"Isn't that right? If Li Dongzhu gives more, he will compensate. If he gives less, we will think that Li Dongzhu will earn all the money."
"Li Dongzhu, give us a rough price. We will change the price accordingly."
"Don't make things difficult for Li Dongzhu. Hasn't Li Dongzhu given enough benefits?"
The commoners at the side touched their consciences and didn't want Li Yi to suffer losses.
Li Yi smiled and nodded. "Alright! I can buy it. I can still make money. The purchasing price is different from the selling price. When the selling price is high, you can sell it yourselves. "
Li Yi was also not clear about the market. Other people had other ways of making leather, and the price of tannin extract was not easy to determine.
He needed to look at the cost of producing tannin extract for the local people, mainly the difficulty of obtaining the raw materials and the cost of time.
Next, the efficiency of tanning leather with tannin extract and the efficiency of other methods was calculated to produce a comparison.
Only then would he know how much he could sell it for. He also had a leather tanning business in Zhuangzi.
The other was drilling to see if the drilling platform with tannin extract could save labor time.
Another type was used to purify water. If the water was not clean, some tannin extract would be sprinkled in, and the dirty things in the water would be condensed together with the tannin extract.
In the 1990s, when the tap water was polluted, tannin extract would be given out and wrapped in paper for the residents to use.
"Purified water … seawater? Tannin? Voyage! "Li Yi suddenly knew how to sell tannin extract at a high price.
Purified seawater with tannin, added it to the boiler, and evaporated it using solar energy to make water for people to drink.
"The uses of tannin extract …" Li Yi began to speak as if he was giving a report.
The eunuchs and palace maids ignored the cold weather and grabbed their brushes to take notes.
When they heard the uses, they immediately understood that it was a technique.
The commoners seemed to have a tacit understanding and stopped talking. They listened to Li Yi. It didn't matter if they understood or not, they just listened.
They felt that Li Yi was very knowledgeable. Li Yi once threw out a lot of plagiarized poems, and the commoners in the county could still recite a few.
"Because the sea is vast, there will be many types of rubber people in the future." Li Yi sighed after he finished talking about the uses.
"Brother Yi, can tannin extract be used to turn seawater into drinkable water?" Li Chengqi was in charge of the sea, and he attached the most importance to this.
"Anyway, it is much better than drinking seawater directly. Drinking it directly will kill you. There is not only salt in seawater, but also other things.
In the future, people who go out to sea will sell tannin extract to them. Now …
From today onwards, boil water to soak the acorn shells, and then extract and dry them according to the method. We will buy them at a high price. "
Li Yi said and shouted to the people around him to hurry up and get to work.
He thought of the Department of Shipping in Guangzhou City. His men from Zhuangzi were officials there, including the Winged Knights.
"For those who are willing to make tannin extract, each family will be given five grams first. After that, we will calculate the amount according to the quantity."
Li Yi looked at the people in hemp clothing and decided to give them money first.
He wanted to send the tannin extract to the barbarians in Guangzhou and tell them that this stuff can turn the undrinkable seawater into drinkable water at a critical moment.
"Li Dongzhu, tell everyone, five grams is too much. How much do you want?" Du Xin stood up and asked on behalf of his people.
"One gram of processed powder, fifty grams." Li Yi quoted.
One hundred grams was five grams. He turned around and thought that he could sell it for one gram of five grams. No, fifty grams. Let's see if anyone wants to buy it.
When he first sold it, the price was even higher. One gram was one hundred grams. It was a life-saving item when there was no fresh water at sea.
"Okay, let's do it. After the meal, go back and look for acorns. If there is nothing to peel off, use your hands. Li Dongzhu will pay for it."
Shi Laoliu shouted loudly. The other people clenched their fists. They couldn't wait to keep Li Yi in the county.
Children were the happiest. When the adults were happy, they felt that the whole world was beautiful.
The sun was so bright, and the weather was not cold at all.
Li Yi went back and sat down for the meal. Li Chengqi asked: "Did you tell Bi Goo?"
"Pay taxes. You have to pay taxes when you go through customs. Thirty percent. You don't have to pay extra." Li Yi was generous. He never took the initiative to avoid paying taxes.
He told Bi Goo and Li Longji that he wanted to collect taxes. If he tried to find a way to avoid paying taxes, wouldn't his lifespan be deducted?
After Wu Jieyu knew the situation, she showed a vexed expression: "We can't keep it a secret. Otherwise, we should make it ourselves. In the future, we can plant a lot of it and spread it out."
Empress Wang looked at the happy people: "The people are benefiting. We are helping them. Uncle can make money by processing seawater with tannin extract today. Tomorrow, there will be other ways to make big money. "
"Yes!" Liu Jieyu agreed. She had a good impression of her son-in-law. Her son-in-law had many ideas. When he came out, how many good ideas did he come up with to benefit the people?
"No matter how many, as long as the barbarians don't learn it, we can still make money when we export it.
Moreover, it has a wide range of uses. We can't keep it a secret for export. We should help improve the people's living standards in the Tang dynasty. "
Li Yi didn't think of secretly making it himself and then exchanging it for money.
Oak trees were widely distributed in the Tang dynasty. The people ate them. It was the most convenient to make cold jelly.
At this time, Wang Wei came over and glanced at Li Longji and the others. Seeing that they didn't show any disgust, he stood behind Li Yi.
"Li Dongzhu, do you know that there are a lot of acorn insects here? Do you have a way to deal with it? "Wang Wei wanted to confirm Li Yi's magic.
Li Yi didn't answer Wang Wei's question. He turned his head and asked Princess Yongmu, "Wen Tian, what should we do if there are a lot of insects?"
"Can they be eaten?" Princess Yongmu asked.
