After eating at the restaurant, Su Jinyu was not in a hurry to go home, she wandered around the street, and by the way, she wanted to find a shop where she could buy salt and stone directly.

This is naturally not easy, after all, the salt in the hands of salt merchants is purified after salt stone.

Moreover, it has to be mixed with toxic salt, and even if everyone knows about it, it can't be directly put on the surface.

Therefore, after walking for more than half an hour, Su Jinyu couldn't buy it, but she was not depressed, so she simply bought some fruits and went home.

Washing the fruit and taking one of them, she leaned back in her chair and pondered the back that she had passed when she went out.

Although it doesn't look like Yan Yu is dressed up, the back is ......

After all, it's her own man, even if she changes, she still recognizes it.

But since he has changed, it means that what he is experiencing now is very difficult and dangerous, so she will definitely not be able to recognize him, so she can only wait, waiting for him to come to her.

Su Jinyu knew in her heart that if Yan Yu really ran into trouble, even if he knew that he had come to Yancheng, he would not take the initiative to come to him.

After all, if you come to yourself, you may bring danger to yourself.

This kind of thing, according to his temperament, will definitely not do this, and I don't know, is he and Lu Zhewen still acting together at the moment?

After eating the fruit and throwing the core aside, Su Jinyu washed her hands and lay on the bed.

There is no result today, and she plans to go out again, even if she buys poisonous salt stones, it will be a good thing.

Thinking in her heart, she soon fell into a deep sleep.

Yan Yu already knew that Su Jinyu came to Yancheng, but Lu Zhewen didn't know it yet.

In contrast, progress on his side was not as smooth as Yan Yu's, but again, his security was higher.

Lying in his room, he pondered what to do next.

It's not that he doesn't do much, but he is very worried that his actions will expose him and even implicate Yan Yu.

After all, some of the people in Yancheng were subordinates of the Six Princes, and some were still familiar with him.

Even if he had found a substitute for the dead ghost before, if he appeared and showed a little bit of his feet, he would definitely be discovered soon.

After tossing and turning, he couldn't figure out what to do for a long time, so he simply sighed and simply rested.

This night, neither he nor Yan Yu slept well, Lu Zhewen didn't know what to do next, and Yan Yu was worried about Su Jinyu.

Even if she knows that she has space and knows the rest, she will still be worried.

In contrast, what Su Jinyu said was quite good, and the next morning, after breakfast, she went out refreshed and continued to look for the unrefined salt stone.

Naturally, it was not easy to find in Yancheng, so she suddenly thought of the short-term job that worked for her before, so she went to find one of them with the idea of trying it out.

"Salt Stone? What does Childe want to do with that? When I heard that she wanted a piece of salt stone, I was a little surprised.

"Don't do anything, it's just curiosity, this is Yancheng, I heard that some of the salt stones are very beautiful, I pondered, it's good to put it at home, it's a thought."

Smiled in response to the short-term work, chatting before, she said that she was from Suicheng, and said that she was only staying here for a short time, and she would go back in the future.

Naturally, the short-term workers would not suspect anything, and now she said that she was at home, and she only thought that she wanted to take it back to Suicheng.

"That's right...... To tell the truth, the general salt stone is not as good as the poisonous salt stone, if the son is just placed at home, why not buy a poisonous one directly, as long as the son does not lick it, it will not be poisoned. ”

After all, it's the local people, and they know better about this.

Su Jinyu couldn't wait for the poisonous salt stone, and her eyes suddenly lit up, "Really?" Toxic salt** good-looking? Can I buy it? ”

"Hey, what to buy, I have it at home, just give you two yuan." The short-term worker has a good impression of Su Jinyu, after all, he is generous.

"I'm so embarrassed, if there is a normal salt stone, find me a piece too, I can have a comparison."

"The money still has to be given, and in gratitude, I have to invite you to drink!" The short-term workers are also very good, and Su Jinyu naturally wants to repay the favor.

"If Childe insists, then listen to you!" Laughing in response, soon, the short-term worker brought Su Jinyu two poisonous salt stones, and a non-toxic one.

The non-toxic ones are relatively small, after all, after purification, salt is very expensive.

The poisonous one is bigger, which fits Su Jinyu's thoughts.

gave the money to the short-term worker, and took him to the tavern for a drink, Su Jinyu returned home with her harvest satisfied.

The salt stone was placed on the table, and she didn't rush to do anything, but first looked carefully.

Indeed, poisonous salt stones are obviously more poisonous than non-poisonous ones.

In addition to this, there are many places that are also different.

With one of the poisonous salt stones, Su Jinyu entered the space and found a recipe to purify the poisonous salt stones according to the above methods, and make the salt purified by this salt stone non-toxic.

The recipes in the space are simple and complex, but overall, they are relatively easy to operate.

This is a good thing, after all, it is easy to operate, which means that after mining salt stone, the amount of salt produced can be greatly increased, and more importantly, it is easy to operate, and the price of salt will be reduced.

At that time, the people could afford to eat it, and it was still non-toxic, and even if they bought it and knew how to purify it, they could become non-toxic, so as not to harm the whole family.

The last time I came in for the experiment, it took a day and a night, this time Su Jinyu had a long heart, and deliberately brought food in, and while waiting, she ate while looking at the recipe.

It's also a blessing to her that this space is really a blessed place, otherwise, when purifying, those smells or something, really make her panic.

Poisonous salt stones want to be purified and then turned into non-toxic salt, although the operation is relatively simple, but the time it takes is more time than usual.

When Su Jinyu came out of the space again, it was not only a day and a night in the past, but it took another day more than the last time.

But fortunately, the purification was successful, and the salt turned into toxic salt stone was non-toxic.

Not only that, the color of the salt is whiter than that purified from non-toxic salt stone.

This kind of appearance looks more expensive than the original salt, but in fact, the cost is very cheap.

Looking at the purified salt, Su Jinyu couldn't help but think about it, if she wanted to buy a poisonous salt mountain and purify it herself......

Is it possible to spend the least amount of money and get the most benefits?

In contrast, it is clear that purifying non-toxic salt is much more profitable than making sugar from sugar cane or sweeteners.

But this money is very difficult to earn, and she definitely can't do it herself.

Thinking of this, Su Jinyu's eyes suddenly lit up, and she thought of a suitable person.

She had always been a resolute person, so she immediately went into the house, found a pen and paper, and wrote a letter.

There was someone in the shadows to protect her, so she thought of finding someone and asking him to send the letter to the capital......
