happily plucked the salt mushroom, and then began to collect the salt blocks.

The two of them were busy until the sun was overhead, and then they hurriedly carried the basket of salt back home.

When their father and daughter came back, Mrs. Su looked at so many pieces of salt and immediately smiled.

"I don't have to buy salt anymore, where did I get it? Take a graphite and crush it and put it away, and you can use it next time you cook."

It wasn't until this moment that Su Muyao didn't know that the reason why the salt she came here to eat had a bitter taste was because these salt cubes were directly mashed and used before they were refined?

Isn't it so scary? This can't be directly poisoned, right?

There are so many harmful substances in this, no wonder the average life expectancy of the ancients was not long.

Fortunately, in order to live a good life in ancient times, I made up a lot of knowledge in ancient times before I crossed over, including salt making.

"Grandma, this can't be eaten, there will be a slight poison in it, and if you eat it for a long time, there will be all kinds of problems in the body."

Old Mrs. Su looked at this big basket of salt cubes, and she only felt a lot of heartache in her heart.

"It's a pity, you can't eat it, what are you bringing back for?"

Mrs. Su wondered in her heart that she couldn't eat it, what was the use of bringing it back?

"Grandma, this is indeed the kind of salt you usually use, but this salt is a little bitter, and this bitterness is the impurities in it, if you eat too much of this impurity, your health will be bad."

Although Mrs. Su didn't understand much, after all, she had eaten this salt all her life, and she suddenly told herself that this salt was poisonous, and she really couldn't accept it.

Seeing that the old lady was deep in thought, Su Muyao continued: "This salt only needs to be purified to be edible, and there will be no more impurities, and it will not be bitter."

Old man Su also listened to the conversation between the grandfather and grandson at the door, and suddenly seemed to realize something.

I saw that Old Man Su went to the courtyard to bolt the gate first, and then hurried back to the stove room.

"Good baby, let me ask you, is this the green salt you are talking about refined by the dignitaries."

Su Muyao thought about it, the green salt they were talking about was actually the refined salt, but the refining method was different, but there were still a lot of dirty things in it.

nodded, "Grandpa, it's probably the same as you said, but my refining will be much better than green salt."

Mrs. Su didn't know, so she looked at her old man, "Why are you so excited?" ”

"Hey, old woman, you don't know that only people in the palace or dignitaries can afford to eat this green salt."

seemed to think of something, and then said, "In the early years, I went to work as a helper in other people's kitchens, and I met dignitaries, and people came to the store to eat, but they all brought their own green salt, and the salt was called a beautiful one."

As soon as Mrs. Su heard her old man say this, could it be that kind of salt is very expensive? I thought of so much refined salt that my little granddaughter took out some time ago.

Hurriedly took out the salt jar and handed it to the old man, "You see this is my good baby, I took it out for me some time ago, and all we have eaten in our family recently is this salt, can you take a look at the green salt you said?" ”

Old man Su held the salt shaker's hand and trembled, "This is better than green salt, it is even thinner and whiter, how can there be such white salt?"

Seeing the trembling hand of her old man, Mrs. Su snatched the salt jar.

"Look at your unproductive appearance, our good baby is a little lucky star, and God has to chase after the kind of good things that feed you in the future."

Old man Su smiled.

Here, Su Muyao found a suitable gauze from the space and found a clean wooden barrel in the kitchen.

Only then did he pick out a few small pieces of salt from the basket of salt that Su Laosan took back and put them in the basin.

Scoop water again, pour it in, add plant ash to boil and let stand before filtering.

Holding a large iron spoon and stirring it slowly, he covered one side of the barrel with gauze and began to pour salt water into the other bucket.

This is followed by a gauze filter, which can filter out the insoluble matter.

It took several rounds to pour the filtered water into the pot.

Looking at the large amount of impurities on the cloth, she knew that the so-called green salt was probably just a matter of melting the salt water and filtering it through the cloth, even if it was completed.

The salt that flows into the market is basically filtered and then sold to these people.

I didn't think about the impurities in it at all, and there may be trace amounts of toxins.

As soon as Su Muyao sat on the bamboo stool and planned to continue the fire, she was hugged aside by her grandmother.

"Just come to this grandma, what do you have to do and let your grandpa help you."

The old lady has already seen it once, and there is nothing special about these fires, just do it yourself.

Mrs. Su lit the firewood with flint and steel underneath, and Su Muyao began to use a spoon to continuously stir the salt water in the pot.

Just kept stirring, kept stirring Old Man Su on the side, and finally understood that his little granddaughter had to stir the water all the time, so he took the big spoon in his granddaughter's hand and started stirring in a good way.

Finally, crystals appeared in the pot.

"Grandma doesn't need to continue to add fuel to the fire"

When Mrs. Su heard this, she didn't continue to put firewood in it, clapped her hands and stood up, watching her little granddaughter standing on tiptoe and still busy on the stove.

Su Muyao was waiting for the embers and slowly dried the salt water in the pot.

After a while, what came out was the white crystal salt.

The salt in the pot has crystallized, and there are only two large bowls of salt when so many salt cubes are completed.

Old man Su only saw his little granddaughter's pot of salt water as if in a dream, which turned into the salt of this white flower.

said to his wife, "Wife, pinch me"

Mrs. Su pinched her old man angrily.

"It hurts, it's not a dream"

At this time, Old Man Su was already thinking about having this technology in his heart, whether to keep it private for himself, or to discuss it with the village chief and report it to the government.

This privately made crystal salt, that is a big crime of killing the head, if it is discovered, it will be connected to the nine clans.

But if you take the initiative to report that you have found a way to make crystal salt, there will only be a reward, no punishment.

But I am afraid that my little granddaughter will be implicated, after all, this method may offend many people, so forget it!

"Good baby, if you do this once, you can't do it in the future, don't say anything to anyone! Don't even talk about your father and a few uncles in the family."

When Mrs. Su saw her old man say this, she also had a plan in her heart.

This is indeed a very big event, if you let outsiders know that your little granddaughter may not be able to keep it.

They don't need to be rich and rich, they just want their little granddaughter to grow up safe and happy.
