Under the lid, a handful of table salt made everyone puzzled.

It was Lin Su, who looked calm and relaxed.

"That's right, since Mr. Lu is a salt merchant, of course I want to sell you salt, if it's something else, wouldn't I have found the wrong owner?"

Lin Su nodded with a smile.

"Guogong, please forgive me for being stupid, I really don't know the agreement of Guogong?"

Lu Junren frowned slightly.

The salt mine is owned by the state, and he wants to buy it for himself.

I'm afraid this is not something that a national prince can do.

"Mr. Lu, may I ask, what is this?"

Lin Su sold a pass and opened another lid.

"Xixia Qingyan, this is not difficult for me."

Lu Junren looked at the cyan green salt, as a salt merchant, how could he not know.

"So, what about this?"

Lin Su finally opened the last lid.

I saw that in the porcelain plate, a handful of white fine salt appeared in front of me.

When he saw this, Lu Junren was stunned.

The wheelchair stepped forward and gently pinched it.

"It's salt...... But it's not green salt, and the texture is more delicate than green salt......"

Lu Junren took some salt and put it in his mouth.

"Some tastes similar to Song salt, but it is purer than green salt, I don't know Guogong, where did you find this?"

As a businessman, Lu Junren instantly saw a business opportunity.

If you can sell this fine salt, it will naturally go to the next level.

But where did Lin Su find such a treasure in such a short period of time?

"I just want to know, is this a treasure?"

Lin Su didn't answer, but sat on the chair with a smile.

"Of course, if the prince has this thing, I am willing to go through one or two, as many as I want."

Lu Junren does not deny that this fine salt is indeed a treasure.

"Five? It's too high, if you count it, fifty wen and one or two are enough! ”

Lin Su's words made him even more confused.

Leng Ling was also surprised.

A thousand copper coins are called consistent, and Lu Junren bid five yuan, but he only needed fifty yuan.

has always talked about high prices, but how can he still lower the price by himself.

"Guogong, Lu has never traded like this in his life, I don't know what Guogong's intentions are?"

Lu Junren vaguely felt that Lin Su played a big game of chess.

I became a chess piece, and I was in the chess game, and I didn't know what was going on at all.

"Fifty wen and one tael of salt, the people can afford to eat, otherwise wouldn't it become the exclusive enjoyment of high-ranking officials and nobles, it is not reasonable, and it is not in line with me!"

Lin Su's words finally made Lu Junren have an epiphany.

"Guogong is really broad-minded, it is Lu...... Shame on you! ”

With this refined salt, I don't want to make money, but I want to benefit the people.

This made Lu Junren, who didn't have much nostalgia for his family and country, suddenly have a sense of shame.

"Mr. Lu doesn't need to be too humble, you and I stand at different angles, naturally have different ideals, I won't talk about the big truth, in fact, this refined salt is also obtained in Mr. Lu's house, that is, the coarse salt you see!"

Lin Su no longer sells Guanzi, because he knows that if it is useful, one sentence is enough.

As he spoke, he reached out and grabbed the coarse salt like rock sugar.

"Taste...... Wrong! ”

Lu Junren, who has been fighting with salt all his life, is a little unconvinced.

What is the taste of Song salt, how can he not know, and how can it be compared to refined salt.

"Of course not, because I used purification technology to filter impurities, according to my calculations, seven taels of coarse salt, you can extract one or two taels of refined salt, Mr. Lu should know, what does this mean?"

Lin Su smiled and swept the coarse salt in his hand.

These words made Lu Junren suddenly stunned.

The amount of seven to one extraction greatly reduces the cost.

And there's more to it than just being cheap.

"If it is really as Guogong said, this refined salt can not only benefit the people, but also cut off the arm of Western Xia, and from then on, green salt will be extinct in the world!"

Lu Junren's words made Lin Su nod with satisfaction.

"That's right, so if this treasure is sold to Mr. Lu, it should be able to exchange it for some military expenses, right?"

The green salt of Western Xia has always been the salt only available in the border areas.

It has also become the main way of private salt.

The price doubled again and again, if it was a tael of green salt and shipped to the south, the price was comparable to silver.

So over the years, I don't know how many people have sold illicit salt for the sake of this outbreak of business.

But if there is the refined salt extracted by Song Yan himself, then not only will there be no smuggling of green salt, but it will also hit the economy of the entire Western Xia.

"I just don't know, will this extraction technology be very complicated?"

Lu Junren did not make judgments.

Everything is what Lin Su said, and he has never seen it to be true.

If the process is complex, the labor loss will also increase.

"Of course, the extraction technique is not complicated, but because it is a secret, I also ask Mr. Lu to come with me, and I will personally operate it for you."

Before negotiating the price, Lin Suke would not let his technology be shown to others casually.

So he took Lu Junren all the way to his previous carpenter's house.

As for the others, they are all waiting outside.

"Mr. Lu, this is the purification process, I'll do it again!"

Lin Su pointed to the wooden barrel cauldron in front of him, this was the extraction tool he made.

"Then it will be bothering the country."

Lu Junren sat in a wheelchair and watched Lin Su's operation.

He took about a pound of coarse salt, and Lin Su put it in hot water to dissolve it.

The thoroughly melted brine is then poured into a bucket.

The top is wrapped in two layers of satin to form the effect of a filter.

The diluted brine was filtered for the first time.

In this way, one-fifth of the original brine disappeared, and he poured the brine back into the original pot.

After boiling it thoroughly, the water vapor is discharged by distillation.

"Mr. Lu, come and see!"

When Lin Su opened the lid of the pot again, a layer of fine salt appeared in front of Lu Junren's eyes.

Distillation technology is an invention of later generations, which is absolutely something that has never happened before for Lu Junren.

"Guogong Dazhi, I didn't expect to have such ability, Lu really admires it!"

Lu Junren stretched out his hand, took a little salt from the pot, and put it in his mouth.

Sure enough, it tasted exactly the same as just now.

When everything is clear to him, such a magical place really makes him feel ashamed.

As a conservative businessman, he had to re-examine the somewhat young man in front of him.

He has long heard of the bravery on the battlefield.

But today's appearance of the wheelchair and purification technology made his impression of Lin Su completely collapse.

"Mr. Lu, I wish us a happy cooperation!"

Lin Su smiled and handed over a glass of wine.

With this purification technology, he can not only obtain a large amount of military spending, but also subvert the current pattern.

"Ahem, ahem, ahem......"

Before Lu Junren could speak, the strong smell of wine made him cough lightly.

"By the way, this is the wine after the purification technology, the taste is a little strong, Mr. Lu should be careful!"

Lin Su smiled faintly, in the experiment last night, he also purified the wine of the Great Song Dynasty.

The hand in front of me is holding a high-altitude wine of more than 50 degrees.

Compared with the liquor of the Song Dynasty, which is similar to beer, the quality has changed amazingly.
