I am the son of Cao thief, start the awakening of the tyrant system

"No, brother Zizhong, you misunderstood me."

Cao Mao shook his head and smiled softly.

These words made the three brothers and sisters of the Mi family a little confused.

"Husband, if you don't plan to start with the salt tax, is it possible that you plan to sell salt?"

Mi Luyun was puzzled and authentic.

"The one who knows me is Lu Yun."

Cao Mao let out a long laugh, nodded and said,
"Yes, I plan to sell salt!"

Mi Zhu was taken aback for a moment, then smiled bitterly and said,
"My lord, selling salt is indeed profitable, but where do we get the salt?"

Hanoi County is located inland, far away from the sea. It is impossible to obtain salt by boiling seawater.

And if you want to resell your promise, the cost is too high, and the profit is meager, so it can be said that the gain outweighs the loss.

Cao Mao smiled mysteriously, pointing to the map of Hanoi County hanging on the wall behind him,
"In Hanoi County, there are a total of more than a dozen salt ponds. We can mine salt from these salt ponds and sell them!"

The three of them opened their mouths wide open, as if they were surprised by Cao Mao's thoughts.

It took a long time for Mi Luyun to be dumbfounded,

"Husband, don't you know that those mineral salts are poisonous and cannot be eaten?"

"Of course I know! But what if I have a way to make those poisonous mineral salts non-toxic?"

Cao Mao looked at the three of them with piercing eyes and said.

quiet!
The hall was quiet!
The three of them stared at Cao Mao dumbfounded, some couldn't believe their ears.

Mi Zhu was the first to react, and whispered excitedly,
"My lord, if you really have a way to make the mineral salt edible, then we will definitely get rich!"

At that time, Guan Zhong reformed the salt and iron monopoly system, and relying on the huge profits in the salt administration, Qi finally became the head of the Spring and Autumn Five Hegemons!
And the Mi family has lived in Xuzhou for a long time, so they naturally know how amazing the profit of the salt industry is.

It's just that Xuzhou Tao Qian will firmly control the Yanzheng at that time, and they have no way to start!
"Of course I have a way!"

Cao Mao brought the three siblings of the Mi family to a courtyard behind the mansion.

Although this courtyard is inconspicuous, the outside is full of soldiers in charge of guarding, fearing that even mosquitoes cannot fly in.

The three brothers and sisters of the Mi family followed Cao Mao into the middle of the yard.

I saw more than a dozen servants in the yard, busy with something.

Cao Mao led the three of them to a desk.

On the left are several off-white or even black salt blocks.

On the right is a pile of refined salt that is as white as snow and finely sanded.

"Do you think these two piles of salt have anything in common?"

Cao Mao asked.

The three brothers of the Mi family fell into deep thought.

After a while, Mi Fang still shook her head,
"I don't see any similarities."

The salt blocks on the left can be seen from those poisonous salt mines at a glance.

If you eat these mineral salts, you will suffer from vomiting and diarrhea in mild cases, and in severe cases you will die.

And the crystal clear salt on the right is all in the shape of fine sand grains.

Even compared with the fine salt produced by the Qingzhou Salt Factory, it is several grades higher!
How could the two have anything in common?

Cao Mao laughed but said nothing.

Mi Luyun at the side hesitated for a moment, then said softly,

"Husband, could it be that these refined salts... are extracted from mineral salt?"

"Not bad!"

Cao Mao nodded heavily!

"Impossible, absolutely impossible!"

"How could these refined salts be extracted from mineral salts?"

Both Mi Zhu and Mi Fang shook their heads.

"You don't believe it?"

Cao Mao squinted at them and said with a smile,

"Then follow me!"

He directed the servants in the yard to get busy.

The most fundamental reason why mineral salt is inedible is that there are too many impurities.

What is contained in it is basically the periodic table of elements!
Although the ancients did not know how to remove impurities, Cao Mao, as a traveler, naturally knew how to purify it!

Under his command, the servants first crushed the salt block, and then ground it into a fine powder with a millstone.

Then he found a sieve to remove the larger impurities.

The remaining mineral salt was put into a basin of clear water.

The two quickly merged together.

The servants found two more layers of sackcloth, covered the wooden basin, and then poured out the liquid in the wooden basin.

The liquid at this time is much clearer than before, and the impurities have almost disappeared.

But this is not enough.

The servants wrapped the crushed charcoal with two layers of sackcloth, and filtered it again.

At this time, the remaining solution, except for white, is already quite clear!

The servants set up a cauldron and began to boil the solution.

When the water in the pot was gradually boiled dry, the white salt appeared in front of them!
"You can try it, is it similar to the refined salt you usually eat?"

Cao Mao smiled lightly.

Impatiently, Mi Fang stepped forward, dug a piece with her fingers, and put it in her mouth.

For a moment, his face twitched, and he couldn't help winking.

But before he had time to rinse his mouth, he turned his head and said to Mi Zhu and Mi Luyun with ecstasy,
"Brother, little sister, this... this is really table salt, not bitter at all!"

Mi Zhu and Mi Luyun also looked dull.

If they hadn't seen it with their own eyes, how could they believe that those poisonous salt blocks would turn into white salt!

But after the surprise, the two couldn't help showing excited smiles!

In the refining of salt in the late Han Dynasty, most salt farms were set up by the sea.

Salt is refined by exposing salt fields to the sun and boiling salt with forage.

Because of this, after the salt was transported to inland Silizhou, Liangzhou and other places, the price of salt was more expensive than the price of meat!

It is no exaggeration to say that a catty of salt can be sold for one tael of silver, which is relatively cheap.

The method invented by Cao Mao is low-cost. If you open a saltworks in Hanoi County, it will be even more profitable than huge profits!

Even though the Mi family has a great career, the three brothers and sisters are also full of excitement, and even their breathing becomes short of breath!

"This kind of salt refining method, remember not to tell outsiders, understand?"

Cao Mao exhorted.

"understand!"

Mi Zhu nodded repeatedly.

Just kidding, such a way to make money, they will only tell others when they are full!

Mi Fang said cautiously,

"I don't know my lord, how do you plan to start refining and selling this refined salt?"

"I called you here today because I plan to hand over the salt business to the Mi family!"

Cao Mao said softly.

Hearing this, Mi Zhu and Mi Fang were overjoyed and said quickly,
"Thank you my lord!"

"Just remember, as long as the Mi family is loyal to me, I will definitely not treat the Mi family badly!"

Cao Mao said in a deep voice.

When it comes to doing business, the sum of Chen Gong, Pang Tong, Xu Shu, Jia Xu and others under him is probably not as good as the Mi family.

In addition, the Mi family followed all the way and paid a lot, so it's time to repay them.

"Thank you, lord, the Mi family will remain loyal to the lord from death to death!"

Mi Zhu and Mi Fang said in unison.

When they were forced to serve Cao Mao at first, they were really reluctant.
