" You guys actually didn't add salt!!!"
Liu Xuan exclaimed.
This was what happened.
On this day.
Liu Xuan was training with the soldiers in the valley.
After the training, it was time for lunch.
For a moment, cheers continued.
Liu Xuan noticed the excited looks of the soldiers and was immediately curious.
They were curious about what kind of food could make them so excited.
Therefore, he also ordered a military meal to try it.
The food in the military camp was very simple. It was just a big pot of hodgepodge.
All kinds of meat and vegetables were cooked together.
There was no doubt that its appearance could not be compared to the food of the future.
Liu Xuan took a bite and frowned.
The taste was too light, as if there was no salt.
Looking up to his side, he saw Guan Yu, Zhang Ren, and the soldiers not far away eating happily.
Liu Xuan was confused and couldn't help but ask,""Yun Zhanggong Yi, don't you think this meal tastes very bland?”
Hearing this, the two of them were stunned before nodding.
"Since you feel that the food doesn't taste salty, why can you eat it so happily?”Liu Xuan was even more puzzled.
He felt like he had forgotten something.
"Lord County Governor, you don't know!"
Guan Yu explained," The world isn't peaceful these days. The price of salt has soared. One jin of coarse salt can be exchanged for nearly 80 to 90 jin of grain. Although this meal tastes bland, at least it can be tasted salty. It means that the chef added salt when cooking. It's already very good!”
"That's right, Lord County Governor!"
"It's already very good to have a salty taste!" Zhang Ren echoed.”
"Salt!"
Liu Xuan finally realized what he had forgotten.
This matter was salt production!
The importance of salt was self-evident.
If a person's body did not replenish enough salt for a long time, it would become weak.
Therefore…
Salt intake was very important if an army wanted to maintain its strongest combat effectiveness.
Liu Xuan rushed back to County Governor Manor and summoned Tian Chou and Jian Yong immediately.
"Lord County Governor, may I know why you have suddenly summoned the two of us?”Tian Chou asked.
"Zitai, Xianhe, do you know where there are salt mines under my Daijun?”Liu Xuan asked.
"Salt mine?"
"Salt mine?"
The two of them looked at each other and saw confusion and confusion in their eyes.
"County Governor, there's a salt mine next to the riverbank north of Dai County…" Jian Yong replied.
"Good!"
Liu Xuan was overjoyed.
"Lord County Governor!"
Tian Chou's face was filled with anxiety as he hurriedly said," You can't eat that salt mine. That's poisonous salt. If you eat that salt, your entire body will turn purple. If you eat too much, you'll have diarrhea until you die!"”
"That's right, Lord County Governor. That poisonous salt can't be eaten!”Jian Yong said.
Facing the anxious gazes of the two people, Liu Xuan waved his hand and said with a smile,"What if I say that I have a way to detoxify the poison in the salt?”
" What?!"
" Is Lord County Governor's words true?”
The two of them stared at Liu Xuan with anticipation.
"Have you ever seen me lie?”Liu Xuan said.
"That's great, that's great!"
After getting Liu Xuan's affirmative answer, Tian Chou was so excited that his face turned red. He kept pacing back and forth in front of Liu Xuan.
He had been worrying about the problem of salt for a while.
Now that salt was so expensive, Liu Xuan promised that all the laborers and soldiers would be provided with food.
Since the food was included, then the food must be symbolically added with some salt.
Although he didn't put in a lot, there was nothing he could do!
He had a lot of mouths to eat!
The Construction Corps had more than 40,000 people. Including the 7,000 soldiers, there were about 50,000 mouths.
Even if they only put a little salt in their meals, they would need to use 300 to 400 catties of salt every day.
Three to four hundred catties didn't sound like much.
However, this was only a day's supply!
This was a huge expense!
But now!
His county governor actually said that he had a way to remove the toxicity of the poisonous salt. How could Tian Chou not be excited?
"D-Dare I ask, Lord County Governor, how, how should I remove the toxicity of the poisonous salt?”Tian Chou asked shakily.
"Follow me!" Liu Xuan said.
Soon after, the group of people followed Liu Xuan and hurried to the salt mine in the north of Dai County.
Salt ores could not be eaten directly because they were mixed with various impurities such as nitre, phosphorus, and potassium.
The poison that Jian Yong and Tian Chou mentioned was caused by impurities such as nitre, phosphorous, and potassium.
Therefore…
It was actually very simple to remove the toxicity in the salt mine, and that was to purify it!
Liu Xuan ordered people to dig out a large piece of salt from the salt mine, then asked people to borrow a stone mill from a nearby village.
Next, he first ground the large salt mine with a stone mill, then put the ground salt mine into water, allowing the salt that could be dissolved to dissolve in water.
Then, it was filtered.
The filter was made of several layers of gauze wrapped in charcoal. In order to filter it cleanly, it was filtered seven or eight times.
The purpose of filtering was to filter out toxic compounds such as nitre, phosphorus, and potassium.
After the filtering, the water in the bucket could be called salt water.
Finally, the fire boiled the salt water and evaporated the water, causing the salt dissolved in the water to separate.
Under everyone's bright gazes.
The water in the pot gradually evaporated.
On the bottom of the pot, there was a thick layer of beige substance.
"County, County Governor, this, this…This can't be…This can't be!!!”
Tian Chou looked at the layer of white substance at the bottom of the pot. His eyes widened as he asked with a trembling voice.
Liu Xuan smiled and nodded.”
