Walking out of the eldest grandson's harem, Li Chengyang was in a daze and didn't know what to do.

Now that he has nothing to do, the biggest thing has been settled, Li Gu has won the true biography of Li Chengyang, and the previous few guards have made Li Gu feel like an instructor, as if he has returned to his youthful years, and now even if Li Chengyang forces him not to go, it is estimated that he will not agree.

Don't worry too much, anyway, the back and forth is the set of discipline, some formations or something are still the original moves of the Tang Dynasty, Li Chengyang doesn't know any moves, the boxing method taught by the instructor has been forgotten, and now I only vaguely remember a few names in my mind, what lunges to punch, bounce the crotch and elbows or something.

It has its own merits with the popular step-by-step assassination moves of Datang, but fortunately, it is good to be lazy and continue to use the original method.

walked back to the East Palace, turned left, swayed right, there was no one in the palace, there were two or three guards scattered outside the palace, Li Chengyang even had the mind to buckle a basket and catch birds.

Walking into the kitchen, I looked at the dazzling array of ingredients and had a thought, looked around, and was attracted by a jar of salt.

Picked it up and looked at it carefully, twisted a pinch and put it in his mouth to taste it carefully, frowning.

Salt is fine salt, just looking at the appearance and the salt in the previous life, it is no different, too, the things used in the palace seem to be the best, but you can still feel a little bitter taste when you put it in your mouth, and the bitterness from the tip of your tongue made Li Chengyang smack her lips.

There is something to do next, get some good salt out, the salt will definitely not be sold, at least not now, maybe when the time is ripe, Li Shimin will take out the salt and tea as part of the bargaining chip with the family.

Oh, yes, salt can also be sold to the grassland, a small amount of salt, not a big deal, and the previous plan to sell tea, through the people in the market, to get a certificate to sell salt, disguised as a small family, it is a simple matter.

You don't need to sell too many things, salt is a huge profit, and it is better than tea.

If you look carefully on the grassland, you can still find some anti-greasy vitamin supplements, but salt? Completely dependent on Datang.

Salt in the Tang Dynasty fifty wen a catty, put on the grassland can be more than dozens of times, and never worry about the market, as long as the salt is transported to the grassland, then someone must buy it, this is not to worry at all.

Sitting on the threshold of the kitchen, carefully thinking about the steps of salt making, now Datang's salt industry has a mature technology, and the magazines that can be removed have been removed, and the coarse salt eaten by the people in circulation on the market is now a large piece of salt, which is yellow all over the body, and the whole is translucent.

Li Chengyang can't make salt, but how to purify Li Chengyang can, isn't it just to make some charcoal and filter it in the upper pot and steam it, charcoal will suck most of the magazines away, and the remaining salt is the top fine salt.

Do it when you think of it, Li Chengyang stood up and beckoned the guards to put on a few more carriages, and they will definitely buy a lot of salt in a while, are you prepared.

After leaving the palace, he went straight to the East Market, the amount of salt sold was too large, and the West Market was full of small stalls and shops, which could not meet his needs.

walked to the back door of Yuelai Restaurant, said hello to Xiao'er, took a hundred taels of silver, and came to the largest shop with the guards.

"King?" Li Chengyang looked at the huge sign hanging directly above the shop and read it out.

I didn't expect this to go to the old enemy's shop, and I don't know what happened to Wang Xiao now, don't care about it, buying salt is a serious matter.

As soon as he entered the store, Xiao Er greeted him warmly: "Guest officer, what kind of salt are you going to order, coarse salt, fine salt, and fine salt, and even if you plan to order salt there, there is a way, but the money is enough."

As he spoke, Xiao Er pointed in the direction of the palace and rubbed his fingers vaguely.

"How do you know what I want to buy? I haven't said a word yet", Li Chengyang asked Xiao Er curiously, he didn't believe that Xiao Er would say this to anyone, if that was the case, they would have closed down their shop a long time ago.

"Where this young master says, it depends on your dress, dressed simply, but this jade pendant on your body shows your identity, where is this ordinary person can have, just by virtue of this, you are a nobleman, besides, you are still followed by guards, at first glance, it is a big family", Xiao Er did not hide it at all, with his years of experience, people of the age of this little boy in front of him love to listen to these useless words.

Sure enough, Li Chengyang nodded with satisfaction, touched it in his arms for a long time, took out the one hundred taels of silver, and stuffed it into the small second-hand: "Change it for coarse salt for me, fill the car outside, if it's not enough, you're telling me, and if it's enough, the rest will be rewarded to you."

Xiao Er looked out, there were a total of four carriages, one cart was loaded with 4,000 catties, and he still had a dozen taels left, which was really worth living.

"Come, Childe, please inside, I'll call someone to load the car for you" Xiao Er's enthusiasm suddenly grew a few degrees, and his body bowed to ninety degrees, and he directly greeted Li Chengyang into the inner room, and after serving a pot of tea, he went to the backyard to greet and load the car.

Li Chengyang drank tea leisurely, and finally he also enjoyed the taste of being rich is uncle, this money was not spent in vain, it was not that he wanted to spend this money, he was really afraid that if he didn't spend a little bit of this little two, it would make something bad, and spend money to buy peace, after all, he really didn't have a good impression of the family.

After drinking a pot of tea, Xiao Er also walked in with a fast cloth towel: "Childe, the cars are full for you, make sure that every car is full, otherwise you can take a look twice."

Li Chengyang waved his hand: "No need, I still believe in the reputation of the Wang family, ask more, how much coarse salt do you still have in this shop, why do you look so relaxed when you move out of this more than 10,000 catties, I will still come to buy some in a while, maybe more than this time, I don't know if you still have stock."

Xiao Er's cloth towel wiped the sweat on his head, and his big mouth leaked out two rows of white teeth: "Hey, what do you think you want to ask, this stock is not much, there will be 10,000 catties left, but it's not a problem, as long as you say hello in advance, within five days, this salt will arrive, it's not a problem."

"How many pounds is enough?".

"As long as you say it in advance and pay a deposit, you can do it as many catties as you want."

Li Chengyang sat in the carriage and thought about the scene just now, and couldn't help but feel a little chill in his heart.

How powerful is the family? Tens of thousands of catties of salt, said lucky, this is still a shopkeeper said, five days can arrive, if this is changed to transport troops, wouldn't it be five days to go straight into the heart of Chang'an, this is still on the surface, and I don't know how much power there is in secret.

Unexpectedly, I didn't learn about the internal situation of the Wang family from Wang Xiao, but I got the tip of the iceberg from the second little man in this shop.

Fortunately, these clans don't have any private soldiers, and they won't be able to do anything in a short time, otherwise they don't know how big the threat they will bring.

Pulled a cart of coarse salt to the palace, carefully examined it, and finally found a small pestle for grinding medicine, took a few pieces of coarse salt and threw it into the jar, and slowly grinded it.

After a while, a few catties of ground salt particles appeared in the pot in the kitchen, poured water and lit a fire to heat, and when the water was warm, the salt at the bottom of the water was gone.

What should I do next, I took a few bamboos prepared for Feng Li, chose a section that was not thick or thin, and cut it down, and put several layers of cloth on the bread, the charcoal is always prepared in the East Palace, and the best fine charcoal for the royal family, the quality is not good, and I want to use it to filter it will also get the best effect.

After laying a few layers of charcoal, looking at the dry charcoal is a little monotonous, I remember that I learned how to make a simple filter before, and it seems that I need to put something else.

Let's take local materials, find some sand to come out, and find some blades of grass, anyway, the filtering effect can be a little bit, whether he's right or not, anyway, these things are not poisonous, you can put them in, and each material is separated by a cloth, which is also used as a part of the filtration.

Looking at the finished filter nodded with satisfaction, full of sense of achievement, salt production is a secret in secrets, this is a big killer against the family in the future, with this method, most of the salt mines in Datang can prepare non-toxic salt, as long as this method is popularized, the price of salt will drop again and again, although it is still the lifeblood of a country, but it is functional, not economic.

When the time comes, a penny and a pound of salt, can your family still hold on to the salt industry? It's good not to go bankrupt.

So this matter can only be done by Li Chengyang himself, the guards outside are not at ease, it's not that they don't believe it, in case any of the guards inadvertently leak their mouths, then the bargaining chips in the game with the family will be reduced by one, and the gains outweigh the losses.

Place the strainer on top of another cauldron and take a spoon and pour the previous salt solution into the strainer spoonful.

After a few spoonfuls, the filter began to slowly ooze out pure salt water, and if you look closely, it is very clear, compared with the color of Huang Bulaji before it was not filtered, the filtered salt water has no color at all.

Reborn, as soon as he saw that this kind of filter made up from scratch was really useful, Li Chengyang's motivation came, and soon all the original liquid in a pot was filtered clean, and the cloth on the filter was dyed a little discolored, which shows how many impurities there are in the coarse salt that the people usually eat.

Since it's a test, there's no need for secondary filtering, and if you want to really sell it out in the future, you may still need to filter it again, but that's all for later, just filter it once now, anyway, it doesn't look like a difference from the previous life.

The fire was boiling, and I took a spoon and stirred it constantly, the water became less and less, and some white crystals gradually appeared in the pot.

There was less and less water, and more and more salt in the pot, until the water in the pot was completely boiled dry, and the salt in the pot had gathered a large pile.

Take out a small cluster and put it in your mouth, well, there is no bitter taste, and there is no messy taste, simple saltiness, compared with the fine salt on the side, I don't know how many times better it is just the appearance, there are also some small pieces in the fine salt, the salt made by Li Chengyang is as white as snow, and it will be broken into some powder when you pinch it lightly, and it is a valuable thing at a glance.

Five catties of coarse salt produced less than four catties of fine salt, part of which was lost and then filtered, and some of which ran away with the evaporation of water.

It's worth it, don't say four catties, even one catty is a big profit, this kind of refined salt is not something that can be obtained casually, and the price is all turned up and grown without rising a level.

filled a full can, and walked to the eldest grandson, looking useless by himself, this is still a professional to taste it.

In this palace, who is trustworthy and knows something about cooking, except for the eldest grandson?
