After making up his mind, Yu Zhou will no longer keep it privately, his salt-making method is also simple, it is a boiling word, the history of boiling salt is a long time, as early as the period of the Yellow Emperor of Shennong, there was the Yellow Emperor's minister Su Sha's open sea to boil salt, so many of the origin of sea salt worshiped him as the god of boiling salt.

Yu Zhou's preparation method has been improved, first of all, the ancients only knew that boiling can get refined salt, but do not know why, according to the theory of later generations, the solubility of sodium chloride in cold water and hot water is about the same, and other soluble impurities such as magnesium chloride potassium chloride, the solubility of these things between cold and hot water varies greatly.

Taking advantage of this, Yu Zhou fully controlled the changes between cold and heat, and further improved the accuracy of salt.

Some people may ask, then why most of the later generations are dried salt instead of boiling salt, that is because boiling salt requires fuel, the cost has greatly increased, and there are many ways to deal with soluble impurities in later generations, which can be separated after a series of chemical reactions.

In addition, Yu Zhou also added another process to the boiled coarse salt, that is, the reverse use of brine to point tofu, since the brine can turn soybean milk into tofu, then adding a small amount of soybean milk to the brine can further separate impurities such as calcium chloride and magnesium chloride that can not be precipitated by boiling salt.

This is why Wei Hong smelled a trace of aroma in the refined salt made by Yu Zhou, and the cost of this process increased, but Wei Hong didn't care, his customers were all nobles of the Six Kingdoms who were not short of money, and of course good salt had to be sold at a good price.

And with this kind of refined salt, he can further curry favor with Ma County, the benefits of feudal society are once again highlighted, and then the mediocre monarch can ask his subordinates to be disloyal, and he can let his ministers die and his ministers have to die, but few people covet the secret recipe.

Once you come, grandpa passed it on to your father, and then you will die, and then your father will pass it on to your son, and then you will die, don't underestimate the integrity of the ancients, just like Cui Shu killed the monarch in the Spring and Autumn Period, killing two historians in a row, "The Twenty-fifth Year of Xianggong" is still faithfully recorded.

Getting such a secret recipe, Wei Hong was overjoyed, and the unhappiness of giving two percent of the profit in vain immediately disappeared, this is a treasure that can be heirlooms! With this thing, even for thousands of generations, the descendants of his Wei family can also live well!

Wei Hong thought optimistically, Yu Zhou didn't think so, anyway, it was something with little technical content, and how long it could be kept secret depended on the Wei family's ability.

He is already very satisfied, because he can get 20% of the salt profit without hard work, or Haiyan County, if he is allowed to make salt by himself, it will definitely not be so large-scale, and it is not as cost-effective as earning a star and a half.

As for Ma County's order, it will be left to Wei Hong to worry about, he has already given him a lot of ideas, and the secret recipes have been taken out, if it can't be done, it only means that it is not a person.

When both parties are satisfied, the atmosphere is more harmonious, after the door is opened, the old fox affectionately took Yu Zhou's arm and asked them to stay for a few more days, and Yu Zhou pushed the boat down the river.

In the evening, Wei Hong, who had experimented with the secret recipe, was even more enthusiastic, and the virtuous nephew and nephew kept shouting, and a banquet was pushing the cup and changing the lamp, and the plan was staggered, which made Wei Han wonder who was the son of the Wei family.

Xiang Ji's temper is straight, but he is not stupid, seeing this posture, he knows that the matter of Haiyan must have an eyebrow, and he happily drank a few more glasses, because as soon as the matter is over, everyone can cross the river to find his uncle.

When the banquet dispersed, Jing Xiao took the initiative to find Xiang Ji: "I'll go with you!" ”

Xiang Ji squinted: "How do you know we're leaving?" ”

"Hmph, you've been noisy across the river for the past few days, and today you suddenly had a drink, you must be leaving."

"Are you eavesdropping?"

"Still eavesdropping? Your voice is never lowered, and the things in your heart are written on your face! ”

Xiang Ji was speechless for a while, so he had to fork his head: "The Wei family has your friends, why do you want to go with us?" ”

"When I was born, I had a witch wish, saying that I was the destiny of the Heavenly Evil Lone Star, look at your face and see if you can be killed by me!"

According to Xiang Ji's usual temperament, he couldn't stand the excitement and nodded in agreement, but when he came down the mountain, Fan Zeng and Mrs. Xiang had an explanation, asking him to listen to others more, and secondly, this Jing Xiao's temperament was really unpleasant, and after thinking for a while, he simply ridiculed him.

"You are injured, but the two blood holes in your shoulders are about to be recuperated for a month, what's the matter, you are not afraid of dying halfway?"

Jing Xiao sneered: "Do you think you were joking when you asked you to hold me to block the arrow?" Not only will I go with you, but Situ Yi will also be with me. ”

"Situ is proud of righteousness, quite in line with my taste, what are your skills?"

"Zhong Liyi's martial arts are stronger than mine, but he must not be able to beat me, this is my ability!"

Xiang Ji was about to ask questions, when Yu Zhou walked over from the side: "Brother Yu, bring it, anyway, we will stay for a few more days, and his injuries will be better by then." ”

"Why wait?"

"After the matter was discussed, I wrote a letter for Zhongli to send back to the mountain, and asked Chen Ying to come and continue, and I will count on him to handle it in the future."

Xiang Ji nodded and said, "That's true, but why do we bring this braggart guy?" ”

"Brother Yu, you must know that martial arts emphasize one courage, two strength and three kung fu, even if Brother Jing Xiao's martial arts are slightly weaker than Brother Zhongli's, but his courage is numb, presumably his shots are all life-fighting moves, right?"

Jing Xiao snorted coldly, noncommittal.

"I'm curious, you are so good at martial arts, and you have Situ Yi as your company, how did you get caught?"

"Don't ask what you shouldn't!" After Jing Yu finished speaking, he turned around and left.

Xiang Ji stepped forward: "See, I don't like him, you just spoke for him, but none of them were good." ”

Yu Zhou didn't dare to say that he could completely see through people's hearts, and the feelings in Jing Xiao's dead fish eyes made him even more incomprehensible, but one thing was right, if he wanted to enter the heart of such an arrogant person, he had to do it for a long time.

Situ Yi's virtue is trustworthy, but as long as he can treat people sincerely, his character is almost the same, and I have heard that Jing Yu was originally also a cheerful temperament, but I am afraid that there is something inconvenient to talk about in that national funeral.

Exploring other people's secrets is not necessarily a good habit, at least at the wrong time will only attract disgust, Yu Zhou doesn't want to be annoying, even if the other party is a slightly weird guy, he can accept it.

"Let's go, Brother Yu, let's go enjoy the sand bath for a few more days, why haven't I seen Long Ji?"

Xiang Ji's face suddenly became much weirder: "He heard you say that it would be more refreshing to bathe with some salt in the sand, and then go to see a doctor for ulcers......"

"How is this possible? How long did he bathe? ”

"It's not a long time, it's just that the banquet is coming, so I dragged him out in a hurry, and I just broke a few skins."
