The extraction of salt is not easy, and in ancient times, the easiest to extract was the well salt mine and the lake salt mine.

The salt extracted from these salt mines is the easiest to extract, and of course, the most important thing is that these salts are not toxic after extraction.

But there is also a kind of salt mine, the production of table salt is not less than well salt and lake salt, or even more, but this salt mine is poisonous.

That is the stone salt mine, not to mention the salt produced by the stone salt mine, and there are many distributions in the mainland, but it is poisonous, and the stone salt is poisonous, which is the most fatal defect.

Poisonous things must not be sold, even if it is the Wang family, he will not touch it, it is thankless.

The Wang family also has a stone salt mine, and at first they wanted to extract the refined salt in it, but no matter what method they used, they couldn't do it.

On the contrary, just three years ago, the Wang family had a fatal accident because of the stone salt mine, and finally lost money.

This time, Chu Feng was aiming at this stone salt mine, using stone salt to refine edible refined salt.

The utilization of salt ore is still very low, so there is no need to worry about the amount of salt ore.

Why is the cost of official salt high, the refining technology is insufficient, and whether it is well salt or lake salt, they are more in some coastal areas.

So the cost of transportation is also a big problem, which increases the cost.

But there is no need to worry about the stone salt mine, not to mention far away, near Chang'an City, according to Chu Feng's understanding of the stone mine salt mountain range, there is more than one.

In this way, the transportation cost will naturally go down.

"Chu Feng, do you know that once you make better salt, then the Wang family will definitely kill you at all costs?"

Qin Qiong frowned, after he learned about Chu Feng's salt making, he called Chu Feng to the room to talk secretly.

"If people don't offend me, I won't offend people, the Wang family has long wanted me to die, since that's the case, then let's see whose means are powerful."

Chu Feng knew that Qin Qiong cared about himself, so he explained very calmly.

"Alas, all be careful." Qin Qiong sighed, he was afraid that something would happen to Chu Feng, but in the same way, he also hoped that the salt industry would not be monopolized by the Wang family.

………

The Wang family, originally Wang Si and they were still waiting for Li Shimin's compromise, but what they received was the news of the price reduction of official salt.

Wang Si's hand shook, "Second brother, are you telling the truth?" ”

"This is true, and now many people have already gone to buy official salt." Wang Fen, the chubby middle-aged man from before, spoke.

"This group of Diao people, yesterday they were indignant and condemned the official salt, but today is positive enough, how can this official salt be as good as the salt of our Wang family?" Wang Ming, the third elder of the Wang family, also said angrily.

"Master, why don't we just lower the price back? As a result, there will inevitably be no market for official salt. Wang Fen looked at Wang Si and opened his mouth to suggest.

"No, if we lower the price, then wouldn't it be tantamount to us compromising with Your Majesty?"

"Once we reduce the price, won't everything be in vain at that time, and what will others think of our Wang family." Wang Ming didn't wait for Wang Si to speak, and immediately objected.

"What the third said is right, we can't reduce the price, otherwise we will lose all our efforts."

"The cost of official salt is higher than ours, and now that they are selling at a loss, the Tang Dynasty is newly established, how much loss can the imperial court bear?"

"Tell our people that there is no need to reduce the price, and we must also send someone to purchase official salt and hoard it, once the official salt can't support it, it's time for him to beg us."

Wang Si said with sharp eyes.

The imperial power really made him jealous, but if he really wanted to fight to the death, then Yang Guang's fate would be Li Tang's fate.

"Gao, I'll do it." Wang Fen nodded when he heard this.

Wang Fen immediately sent someone to the official salt sales office to buy salt, but when he went, he found that there was an additional sign with a purchase restriction here.

There was no such thing in the previous news.

Of course, Wang Fen didn't know that Chu Feng was deliberately playing tricks on them.

Besides, even if he refines the salt in the stone salt mine, it will take time, and it will not be done in a short time.

So this limit is partly to extend the time.

After Chu Feng's tossing and turning several times at night in Chang'an City, no brother dared to violate the curfew now.

After all, they were all scared, and anyone with a discerning eye knew that Li Shimin was now protecting Chu Feng.

Three days later, Chu Feng was called into the palace by Li Shimin again, for no other reason, the things that Chu Feng asked him to build had already been built.

At this point, the craftsmanship and speed of the royal family are still very reliable.

Li Shimin also read those things, and some of them he basically couldn't understand the usefulness.

"You kid can tell me now what you're going to do next, right?"

Li Shimin looked at Chu Feng and asked, he didn't expect that he had been fighting in the south and north for so many years, and now one day he would have to rely on a hairy boy.

"Stone Salt Mine, Your Majesty has mastered Chang'an City and the nearby Stone Salt Mine."

"Salt mines?" Li Shimin was stunned for a moment, "This thing will kill people, are you really sure?" ”

Li Shimin is not stupid, so when Chu Feng mentioned the stone salt mine, he knew that Chu Feng wanted to refine the salt in it.

"Your Majesty, rest assured, I, Chu Feng, don't do things that I am not sure of, as long as Your Majesty fully supports it." Chu Feng said lightly.

"I believe you, but around this Chang'an City, there are a total of three stone salt mines, two of which belong to the official family, and the other one does not belong to me."

"In the hands of the Wang family?"

When Chu Feng saw Li Shimin's embarrassed look, he immediately guessed it.

"Yes, in the hands of the Wang family, and it is the largest one." Li Shimin nodded.

"No, this stone salt mine can't continue to fall into the hands of the Wang family, once we make salt, the stone salt mine will not be toxic at that time, it will become a treasure, and it must be taken over in advance."

Chu Feng said with a resolute attitude, since he wants to attack the Wang family, he can't show mercy.

And once the salt is made, it is to subvert the Wang family and replace the Wang family, so the amount of salt will be very large.

Regardless of whether the Wang family has the technology in the end or not, as long as he controls the stone salt mine, he will control his lifeline.

After all, no matter how good the technology is, it also needs raw materials, and it is impossible to make salt out of thin air.

"But now that I have declared war on the Wang family, how can he hand over the stone salt mine to me?"

Li Shimin said with a frown.

Chu Feng also knew that if Li Shimin asked for this matter in person, Wang Si would definitely not give it.

After all, Wang Si is not stupid, and Li Shimin can't directly use imperial power to oppress the family.

If he could, he would have done it a long time ago.

The new establishment of the Tang Dynasty must not cause chaos, so to deal with the family, it needs to be justified and not cause chaos.

"I'll do it." Chu Feng thought about it and then spoke.

He definitely can't give the Wang family a chance, so now he can only do it himself.

"You're going?" Li Shimin was a little confused, "Do you think the Wang family will let you go and be willing to sell you the stone salt mine?" ”

Chu Feng didn't answer directly, but smiled, "Your Majesty, you have to pay for this money yourself." ”

After Chu Feng finished speaking, he directly retired and left, now everything is ready, only Dongfeng is owed, and it is enough to take the Wang family's stone salt mine.

After Chu Feng returned, he began to plan the matter of the stone salt mine.

First of all, Chu Feng let people let out the rumors, saying that he Chu Feng wanted to make salt, and he couldn't get used to the Wang family's monopoly on the salt industry.

Now that the price of salt has risen, this has attracted attention, so this kind of topic has also attracted attention, and it quickly spread and reached the Wang family.

"The head of the family, this Chu Feng is really unashamed, just because he still wants to get involved in the salt industry, I don't know how many people in the world want to get involved, but no one has a good end."

Wang Fen sneered, if it was so easy to get involved in the salt industry and move their Wang family, then His Majesty would not be so jealous of them.

"Yes, this Chu Feng really doesn't know that the sky is high and the earth is thick, offending our Wang family is already a dead end, and he even dares to speak wildly."

"Family master, do you know, what did this Chu Feng say, it is said that he said that he wanted to use the stone salt mine that our Wang family can't even do to extract salt."

"He wants everyone to know about the incompetence of our royal family."

At this time, Wang Ming also spoke, as if he had heard a big joke.

Wang Si was just about to speak, when someone hurriedly stepped forward.

"Family master, there is a person named Chu Feng outside who wants to see you."

"Chu Feng? He still dares to come, there is really a way in heaven that he doesn't go, and hell has no way to break in. Wang Fen immediately spoke.

"Master, I'll teach that kid a lesson."
