In fact, at the end of the Eastern Han Dynasty, people's purification of salt was already a lot of progress, but they did not have a better means to remove impurities, nor did they have a good instrument for screening impurities.

The ancients did not know the adsorption of activated carbon, and the use of charcoal can play a role in the final purification, which is currently only known to Liu Jing, so Liu Jing has confidence in purifying coarse salt.

Hearing that Liu Jing was going to purify the coarse salt, the family was very curious, and immediately got together, watching Liu Jing experiment, Guan Yu, He Gui and Diao Chan gathered there, waiting for the moment when Liu Jing created a 'miracle'.

Liu Jing first took a small bag of coarse salt for experiments, asked Guan Yu to crush the coarse salt with a stone mill and water, so that the coarse salt was fully dissolved in the water, and then smashed the charcoal and wrapped it in fine linen.

Then find a large funnel and fill the funnel with fine linen wrapped in crushed carbon, and then wrap the funnel with a wide fine linen cloth and sink it in the middle, and then ask Tang Zhou to pour the dissolved coarse salt with the magazine into the funnel to remove the magazine.

Eventually, the barrel was filled with a slightly pale white transparent liquid that flowed out of the funnel, and all the impurities in it were gone.

Tang Zhou was surprised, picked up a scoop, scooped up a little salt water, tasted it, and suddenly felt a strong salty taste on the tip of his tongue, but the bitterness in the original coarse salt disappeared.

Liu Jing looked at the wooden barrel with satisfaction, didn't care about Tang Zhou's surprised gaze, let him light the fire again, and poured the salt water into the iron pot to boil.

When the water dried, only a thick layer of salt remained, Liu Jing asked Guan Yu to pound the ground with a mortar, poured it into powder, and then let everyone present taste it, this taste didn't matter, everyone present suddenly felt that the whole person was not good!

This is the real salt, the real salty feeling, they have never tasted such pure saltiness in their lives, and they immediately covered their mouths, took the saliva in their mouths, and couldn't bear to swallow it.

Is this effect still selling? Isn't the customer's demand the market? If such salt is put into mass production, what kind of concept should it be? Liu Jing didn't dare to think about it, his heart was very happy at the moment.

As long as the money can come in a roar and the wealth is accumulated as soon as possible, he will be able to develop his own people as soon as possible, and build an armed force that is truly led by himself in the name of sweeping bandits.

This time, Liu Jing decided not to find an agent, but went directly to the battle by himself, with Guan Yu, an amazing general, by his side, plus his own 'foresight', step by step, slowly developing, not worrying about not being able to develop!

After getting a purer salt, Liu Jing did not delay, so he made a small package, took the fine inkstone, and took Guan Yu directly to Zhang Song's house.

On the tenth day of the sixth month, the scorching summer heat enveloped the whole earth, and the branches of the trees cried day and night, as if they did not know tiredness.

On this day, Zhang Song was splashing ink in the study at home, he was wearing a simple thin gown, but his sideburns were still oozing with sweat drops the size of beans.

The subordinate hurriedly ran in, and said that Liu Jing asked to see him.

When Zhang Song heard this, he immediately put down the brush in his hand, took a wet towel, wiped his hands and face, and said to his subordinates: "What? Liu Gong is here? Please, please, it's a hot day, don't let him wait outside for a long time! ”

Liu Jing walked in with Guan Yu one after the other, and handed over the inkstone to his subordinates casually, and smiled at Zhang Song: "Jing occasionally has to go out to negotiate, and he has to meet a good inkstone. ”

Zhang Song said politely: "Liu Gong will come when he comes, why be so polite, what is the business like recently?" Can Pu Yuan use it easily? ”

As soon as they met, the two of them were polite, Liu Jing greeted Zhang Song as usual, and praised Pu Yuan by the way.

After the greetings, Liu Jing changed his words, and then said casually: "Ziqiao, I have an idea recently, I don't know if it's feasible or not, so I specially asked you to discuss it!" ”

When Zhang Song heard Liu Jing's words, he was stunned, and secretly said that Liu Jing's business has done well this month, and he has become a business star in the entire Nancheng, is it possible that he feels that his foundation is more stable, and he has started Xu Wen's idea?

After Zhang Song finished thinking about it, he wiped the sweat droplets on his forehead with a wet towel, and said easily: "What does Gong Liu think, but it doesn't hurt to say it!" ”

Liu Jing pondered for a moment, and said: "I think that the sale of illicit salt is very profitable, our Zhuo County is surrounded by mountains and rivers, and the salt mines on the mountains outside the city controlled by the government are rich in resources, which is a big fat, but it has always been controlled by the Zhang family.

I heard that most of the money they get from selling salt is in their own pockets, and they do tricks in the account books, and they evade taxes by tens of thousands of taels every year, which reduces the county's financial revenue by half!

I thought about it and thought about it, it is better to let the government carry out competitive management, and the two families will operate private salt together, so that there is an opponent, and his Zhang family will not dare to do more tricks and feet in the account books, and our county's financial revenue will also have a qualitative improvement, and the county keeper's political achievements will be a big cut? ”

Zhang Song thought about Liu Jing's thoughts for a while, and there was a trace of worry in his heart, because the salt merchants in Zhuo County have always been controlled by the Zhang family, firstly, because the Zhang family has a relatively complete purification workshop, and secondly, because the Zhang family has a relatively familiar distribution network.

The sum of these two conditions is the reason why the Zhang family has always been able to monopolize the salt mines in Zhuo County, and even in the entire Youzhou, the Zhang family is also a well-known salt merchant, of course, he is only a small salt merchant, compared to those salt merchant giants in the south of the Yangtze River, his Zhang family is still much worse.

Liu Jing's involvement in the salt mine, although it is not a difficult matter, but it also directly began to snatch food from the Zhang family's tiger mouth, the Zhang family will definitely not give up, and they have already had a holiday with the Xu family, but this time they provoked the Zhang family again, I don't know if Liu Jing can hold it down.

Zhang Song thought for a while and then said worriedly: "Liu Gongna, your idea is good, although the sale of illicit salt is allowed by the government, it is not difficult for me to give you a permit."

But have you ever thought about the influence of the Zhang family? It is not so easy to snatch food from the tiger's mouth of the Zhang family. Besides, the Zhang family has monopolized the salt mines in Zhuo County for more than ten years, with deep roots and a huge business network, why should you compete with him if you are a novice? ”

Liu Jing knew that Zhang Song would have this concern before he came, so he specially brought a bag of pure salt, he slowly took out the package, and said with a smile to Zhang Song: "Ziqiao, you know me, I, Liu Jing, have never fought unprepared battles, No, you taste what this is!" ”

Guan Yu understood, immediately took the package and took two steps forward, and handed it to Zhang Song.
