In the side hall,

At this time, only myself and Mi Zhen were left.

This made Zhang Xiu quite embarrassed. This is so inconvenient for a lonely man and a widow!

Moreover, a gentleman like himself doesn’t seem to be someone who shouldn’t do anything.

"General, it's getting late, let me change your clothes for you!" Mi Zhen's face turned red, and she lowered her head and said in a flies-like voice.

This is the first time her elder brother has pushed herself out, which is considered a political sacrifice. It has been destined since she was born in the Mi family.

"Well, yes, it's getting late."

Zhang Xiu found that she was still suitable for sleeping with a wife. Sleeping like this kind of girl is somewhat guilty, or a responsibility, after all, she cannot be ruthless!

Forget it, this kind of girl is not provoked now, let’s talk about it when she gets married!

Zhang Xiu made up his mind and stopped thinking about it.

There is no way, the little girl is not skilled in her movements, and she can’t compare with the young woman!

After changing clothes and going to bed, Zhang Xiu promised that he had done nothing!

…………

The next day, at the polder.

The fields just released yesterday.

The water of the poldered fields is deeper today, which means that there are more and more fish that can be eaten inside.

After a while, the people caught a lot of big fish.

"Wen Ruo, these silver carp, bighead carp, and carp are not small, and they can't finish eating so much for a while. I want to cut off these fish bladders to make tinder oil."

"As for fish, it can be marinated and eaten for a hundred days, this way, it can save food, and the second is that the fish is extremely nutritious, which is better for marching and carrying."

Zhang Xiu looked at Jia Xu and asked.

"Lord, it's feasible to make tinea oil by fish bladder, but it's impossible to marinate so many fish. Nanyang has little salt, so it can only be supplied by Yuncheng or Xuzhou sea salt."

"However, these supply units have long been monopolized by the aristocratic families. Now, the price of salt in Nanyang and even Jingzhou has always remained high. The coarse salt that people eat costs 1,500 yuan per stone."

Jia Xu quickly dissuaded.

Nanyang is short of salt. If it weren’t for some salt dealers, ordinary people would probably have no salt to eat.

"One thousand five hundred coins per stone?"

Zhang Xiu frowned slightly and gradually shone.

During this period, he worked hard day and night, but he threw some ways to make money aside.

"Is this the price of coarse salt?"

Zhang Xiu suddenly said something and confused Jia Xu's question.

Xu Shu next to him continued: "There are only a lot, and ordinary people usually buy coarse salt from some salt dealers, and the price is about 1,200 yuan."

"As for fine salt, it costs at least three thousand coins per stone, and the quantity is limited, and it is fought over by countless families."

Zhang Xiu nodded while pinching his chin.

Since ancient times, the official business of salt and iron has been very high because salt is the lifeblood of the people and is usually necessary to eat.

Tie controls rebellion. In ancient times, catching salt dealers was like killing drugs now.

"Salt is the lifeline of the country, how can it be transported by other places?" Zhang Xiu said in a deep voice, and then said, "Wenhe knows where there is a salt mine in the surrounding rivers?"

Zhang Xiu checked that the Han Dynasty mainly produced salt in Yuncheng and sea salt, and there were also many ordinary small halide salt mines. However, rock salt was everywhere at that time.

However, it is praised as "toxic salt" and no one dares to eat it!

It is not difficult to purify this thing. He specially consulted the information in his previous life, but it has not been implemented yet, so there is no big problem.

"Salt mine? Is the lord talking about poisonous salt?" Xu Shu frowned and continued. He had been to Jingzhou for several years, so there were not too many such poisonous salt mines. He could find one in almost dozens of miles along the river.

Zhang Xiu nodded, "Can Yuanzhi know where there is a toxic salt mine."

"Lord, there are poisonous salt mines everywhere. What should I do if my lord is looking for it?" Xu Shu asked in confusion.

“Make salt,”

"Make salt?" Xu Shu and even Jia Xu were stunned. The former said anxiously: "My lord must not. Although poisonous salt has a salty taste, it is accompanied by bitterness. Eating too much can make people's whole body purple, and it may even cost human life. It must not be eaten!"

"Lord, what Yuan Zhi said is right. If you eat this poisonous salt a little, you will suffer from diarrhea. Even if people in ancient and modern times have no salt, they dare not eat poisonous salt."

Jia Xu nodded as well. After all, this is not a joke. If this poisonous salt is edible, then Jingzhou and other places will not be short of salt.

Zhang Xiu pursed his lips, not knowing how to explain it, but he felt helpless. This salt ore is edible, but even the salt ore can not turn purple even if it is eaten together!

"The reason why it turns purple is because the salt ore contains other impurities, which can be fatal. Just filter and decompose these impurities, and what is left is refined salt."

Zhang Xiu thought about it and gave a rough talk.

Jia Xu and Xu Shu looked at each other but didn't understand very well, but they caught the point of Zhang Xiu's statement.

"Lord, can you turn poisonous salt into table salt?"

The two of them looked forward to it, but they were still a little unbelievable, because the salt mine cannot be eaten and passed down for thousands of years, and it has long been deeply rooted in people's hearts. How can they be made into salt, and it is also refined salt?

"It should be able to be made, just try it."

Zhang Xiu was not sure, after all, he didn't have enough confidence to know the principle.

Hearing the sound, Xu Shu said anxiously: "I'm sorry General Hu goes ten miles south of the river. If I remember it well, there should be a poisonous salt mine, and I'll pick it up some."

"If it is feasible, the people of Nanyang will never be controlled by others anymore, and the price of fine salt is very expensive, which is really a big income."

Hu Cheer responded and led dozens of riders to take chisel bags and galloped away.

A few moments,

Backyard of the mansion,

At this time, a lot of things were placed in the yard.

A stone mill, a simple funnel, a large piece of linen, a steamer, etc., a few large jars, and some bean-sized nitrate plates.

The salt of the nitr plate will adhere to the blood of the vessel after a long time of boiling salt. It is quite common, and this is also the key to decomposing these poisonous salts.

Hu Cheer was very strong and drove the stone mill and soon crushed the chiseled stone salt into powder.

"Salt powder is put into the tank and add water."

Zhang Xiu recalled the salt making process and directed.

After adding ten kilograms of salt powder in a row, Zhang Xiu personally took a wooden stick and started stirring. The salts needed to be completely dissolved into the water.

Not long,

The salt water in the tank was completely dissolved, emitting a scent of mud and smelling extremely unpleasant. As for the salt water in the tank, it turned yellow-brown and looked a little disgusting.

Seeing that it was almost done, Zhang Xiu ordered: "Hu Er, go and fold the linen twice and seal it at the entrance of another water tank."

Hu Cheer nodded.

Seeing that the mouth of the water tank was sealed, Zhang Xiu grabbed the mouth of the tank with both hands and slowly poured out the salt water in the tank.

A long time,

After pouring a tank of salt water, I saw that a lot of residue, various small stones and unknown crystals were filtered from the four layers of linen.

Uncovered the linen, although the salt water in the tank was a little lighter, it still turned yellow-brown.

"Come again!"

Zhang Xiu rinsed the water tank and put it in the pavement.

After filtering several times, Zhang Xiu stopped until the brine turned pale yellow and impurities were not filtered out.

"Master, that's fine?"

Xu Shu raised his eyebrows and asked.

Zhang Xiu shook his head, and the next step was the last step of filtering.

He took the soybean-sized nitrate plates prepared in advance next to him, wrapped them all in a linen, and stuffed them under a wooden funnel.

After setting up the funnel, a new tank was placed under it. Zhang Xiu reminded: "Hu'er, you come this time, the speed is slower. If I remember it well, this time it should be salt water."

"No," Hu Cheer nodded.
Chapter completed!
