The three of them didn't stop too much, they ate something and set off, and it was a bumpy ride, and it almost turned Huo Guang's stomach out for three days in a row.

Resting at the post station at night, I have to say that the Han Dynasty spent countless hours of time, energy and money on such a long national highway.

In the end, their end point is Jiaoxian, a small county town located on the Jiaodong Peninsula, it is said that the fief of Emperor Wu of the Han Dynasty was the Jiaodong area, so the national highway was specially built to this side, and also helped this side to develop.

There is still a day's journey from the salt field here, continue to play southeast from Jiaozhou, there is no national highway, only ordinary roads, there is no way to make the steel horse travel quickly, can only use the speed of an ordinary horse.

The end point of the destination, the salt field, Huo Guang looked at the map and the approximate location seemed to be near Qingdao, of course, the port city was not of great use in this era, and it was not vigorously developed, and it was still very desolate here.

After walking for a day and a night, I finally arrived at the salt field in Jiaodong.

There are three salt farms in this area, belonging to Jiao County, there is no specific name, the locals call it Qingyan Town, hundreds of families work here, one of which is the salt farm of the Sang family.

In such a small place, Sang Jin didn't have so many scruples, and opened his hat to introduce Huo Guang: "Of the three salt farms here, our Sang family's salt farm is the largest, half of the locals work in our salt farm, and we also pay the taxes for the salt households. ”

The people in the salt works need to pay more taxes because they have stable jobs and incomes, which is equivalent to the treatment of large enterprises.

Soon came to the Sangjia salt farm, covering a large area, boiling the sea boil wave needs the site to dry salt, generally or mainly dry, because the fire to cook has to consume wood, have to spend money, direct sun drying will reduce a lot of expenditure.

Salt in the salt works simply do not need money, transportation and preservation are the places where money is spent.

The person in charge of the salt farm is a side of the Sang family, and it is said that Sang Jin's cousin is named Sang Bo, a young man of twenty-five or sixteen years old.

Because the three of them were particularly conspicuous riding steel horses, Sang Bo took the three of them to the salt field first and introduced them to Huo Guang: "The Sang family is in this salt field, and the average daily salt last year was 120 stones, and now the scale is still expanding. "Of course, the Sang family is not just such a salt farm.

"Yesterday there was a letter before you arrived, it was a carpentry manufacturing drawing, I have ordered someone to build it overnight, fortunately the production process is not complicated, the first purification tool has been done."

As he spoke, he brought Huo Guang into a fully fenced room in the salt farm, and had already arranged a place to prepare for the production of purified salt.

Huo Guang looked at the venue and said, "Let a few of your family's most experienced and flexible workers come in." ”

The people had already been arranged, and Huo Guang didn't hide anymore when he saw the people coming in, and began to teach them how to make pearl salt.

First of all, the salt is dissolved into a saturated solution, in fact, these workers know this step many times, but because they don't know filtration, they can only say that after dissolving, remove some visible impurities, ordinary salt after this operation The taste and appearance are not much different, only some high-quality salt needs to be done like this, and the quality cannot be improved too much if time is wasted, and the price cannot be increased.

But unlike them who selected impurities that were visible to the naked eye, Huo Guang began to filter, and when the first filtration was completed, it was visible to the naked eye that a lot of impurities had been stored on the filter cloth, and once again filtered with a finer filter cloth, and those impurities that were difficult to distinguish with the naked eye were also extracted.

Then it was boiling, and after boiling out the salt, Huo Guang used a saturated salt solution to rinse the precipitated salt in their incredible eyes.

I don't understand, I don't understand, but I'm amazed.

While washing the salt with salt water, he said: "This step you don't look at the change, you can effectively remove the bitterness in the salt, so that the taste of pearl salt is better than ordinary salt, it depends on this step, you must use salt water that cannot dissolve salt to rinse, and after repeated rinsing many times, the pearl salt is completed." ”

Huo Guang didn't intend to teach them the principle, which obviously couldn't be explained as Huo Guang's random idea, and the operation could be said to be discovered occasionally.

After the operation they didn't understand, the pearl salt was completed, and a group of salt workers were also shocked, but they didn't expect the pearl salt to be completed so easily, as long as this process was seen, it could be easily stolen.

Sang Jin said a little incredulously: "Ah Guang, is it that simple? ”

"That's right, the basic process is like this, that is, you can't rush when filtering and cleaning, you have to take your time." Huo Guang didn't hide it.

Sang Jin immediately reacted, once this kind of process is leaked out, it will be made public immediately, so the opportunity for them to take advantage of it will be gone.

Their Sang family still has to rely on pearl salt to quickly occupy the market.

Sang Jin called all the workers present together, and said bitterly that the production process could not be leaked, which can be said to be a combination of grace and power.

Huo Guang and Gan Fu were on the side, and Gan Fu asked curiously: "The process is so simple and easy to get started, as long as you try two more times, you can basically be proficient, are you not afraid that the Sang family will regret it?" ”

"Although it looks simple, but I was also lucky to find a way, the Sang family has such a big family business that doesn't count, the head of the Sang family still wants to save face."

"In front of money, face is not worth mentioning, it seems that you don't know much about businessmen." Ganfu said with a knock on the side.

"Gan Fuzi, I don't think you understand businessmen, and the head of the Sang family will not break his word."

"Why?"

"Because my brother Huo Qu is sick."

"Just because of that?"

Huo Guang said patiently: "The businessman talks about interests, as long as the pearl salt can help the Sang family make money and occupy a large market share, he will not break his promise, he will give me what should be given, or he must give it to me, because in the face of the huge amount of money, they think that my brother will definitely care behind his back, and they break their promise, isn't this just going against my eldest brother?" The Sang family has a big business, and he is not reasonable to do it against his brother, do you think he dares? ”

"But what if you can't make money?"

"If you can't make money, don't count me if you lose money."

"You're really slippery."

"How's that, smart, did you have the idea to teach me how to make a steel warhorse?"

Ganfu smiled and shook his head, "Only honest and simple people can learn to make mechanical creatures. ”

"If you don't want to teach, just say it, don't fool me." Huo Guang glanced at Ganfu.

Ganfu became interested: "Then the old man will test you again, these workers, if they want to expand the constant, they have to teach them the method, there are many people, how to ensure that the method is not leaked." ”

"The leak will definitely be leaked, but we have to find a way to delay it for a year and a half."

As he spoke, Huo Guang looked at Sang Jin, who was talking bitterly about the stakes with the workers, walked up to her, knocked on the big funnel used for filtering on the side, and everyone looked at him.

Huo Guang pulled a stool and sat down, and said to everyone with a cold face: "Pearl Salt is the first project I have cooperated with the Sang family, I don't want any leaks or other problems, if, I mean, if Pearl Salt appears in any other place on the market, I won't verify, I won't ask, I will blame everyone present, all of you." ”
