"How?" Seeing Su Jinyu appear in the house, Yan Yu handed over a glass of water and asked in a low voice.

Taking the cup, Su Jinyu shook her head.

"There's no way around it, after all, neither you nor I are healers." Seeing her shake her head, Yan Yu sighed in his heart.

Indeed, those patients are pitiful, but they are just ordinary people, and there is nothing that can be done to help these people.

The only thing that can be done is to try to purify the sea salt, or send something that might be prevented to where it is needed.

"Or ...... I'll leave later, I'll stay with you for a while, although the recipe is for you, but the matter of sea salt purification, it may be faster with me. ”

I said it before, Fang Zi handed it over to Yan Yu, and Su Jinyu went back to Suicheng, but when something like this happened suddenly, she was a little entangled.

"It's okay for a few days, no more than half a month." Silent for a moment, Yan Yu knew Su Jinyu's temperament too well.

If she wasn't allowed to stay, she would have been thinking about it, and it wouldn't be good for her body.

But if you let her stay, it can't be too long, after all, her body is more important.

Su Jinyu nodded hurriedly, she didn't plan to stay for a long time, under normal circumstances, according to the formula, that is, in a day or two, you can get the result.

After that, it will take a long time, and she will definitely not wait forever.

I want to stay, on the one hand, I hope to help find a way, and secondly, I want to see if there will be any changes in the space in a few days.

After discussion, in the next few days, several people drove the carriage and walked around Jiangcheng.

In addition to checking on the people living outside the city, stop by and find a quieter place to prepare for the purification of sea salt.

It's better to be quiet about this kind of experiment, and when it's completely done, the DPRK and China agree, and it's not too late to be known by others.

Here, Su Jinyu and the others are busy, and in the capital, Pei Yi is also busy.

The emperor decreed that the throne was passed to him, and now the palace and the palace are all in charge of the new emperor's accession to the throne.

The news was sent from the capital, it was sent to Suicheng, Pei Yi didn't know about them going to Jiangcheng, and he didn't know that a letter came from Jiangcheng, which was for him.

Finally, Su Jinyu and the others chose a place that looked good, there were no people around, and it was not far from the seaside, so they could try.

Before that, Su Jinyu considered taking seawater home and experimenting at home.

I don't know if there will be any strange taste when the sea salt is purified, and if you make it at home and be thought to be doing something bad, it will not be good.

The recipe that was to be handed over to Yan Yu before, Su Jinyu had read it many times, and all the things she needed had been bought.

At this moment, she sat on the sidelines and watched everyone busy.

Some fetch water, some make fire, she is a little embarrassed, but it is really inconvenient to mix, otherwise it will become a mess.

Soon, the pot was set and the fire was lit, and about that, the main thing was to listen to George.

His home country, Linhai, purified the salt in the seawater in this way, but in the end, it was somewhat poisonous.

The steps in the early stage are the same as those on Su Jinyu's prescription, with George here, which is still very easy to do.

The seawater was steamed and boiled until it eventually became a grain of salt, the color of which was similar to what George had seen in the past.

He told everyone what he had seen and seen.

"What's next?" Everyone's eyes fell on Su Jinyu, she looked at the recipe, and asked everyone to follow the steps to put other things into the pot together and continue to stir-fry.

"Will this work?" George was curious, but his men didn't stop.

"I don't know yet, although there is a recipe, but the specific ones have to be debugged according to themselves."

The method of purification is written on the recipe, but how much salt is purified by seawater, and how much salt can be left after this salt is purified again, it is unknown.

In the beginning, there is a high chance of failure because the dosage needs to be tried slowly.

Or maybe the method didn't fully grasp and failed.

But don't be afraid of this, if you take your time, you will always make progress little by little, and finally get the answer.

Sure enough, the first time failed.

So they cleaned the pot with clean water and poured it back into the seawater, this time, before it could condense, they added something to it.

The second time failed again, only two experiments were done, and in the afternoon, the group packed up their things and went back to their lodgings.

I wasn't really busy that day, but everyone was quite tired, and after eating and washing, I went to bed early.

Originally, Su Jinyu still thought that she wanted to go to the space to have a look, but she lay down for a while and fell asleep.

It's dawn to sleep.

After eating in the morning, the group went to yesterday's place and continued the experiment, just like yesterday, both times failed.

So the third, fourth, and fifth days......

Although it failed every day, it was not without gains, and the second method on the first day, after constantly changing the dose, looked like it had changed compared to before.

This made everyone excited, so they kept changing the dose according to the current method.

On the eighth day, at last, the purified salt was completely different from before, or at least it looked very different.

But when you taste it, there is still a little bitterness, and you have to remove all this bitterness before it can be considered complete.

"Things have come to this point, don't you stay any longer, go back to Suicheng, right?"

That night, Yan Yu discussed with Su Jinyu, and what he originally said was no more than half a month.

Now that everyone has the hang of it, it's good to keep trying.

"Having said that, as soon as I leave, you will be left alone, but I am afraid that I will not be able to keep busy, and I will delay time."

As I said before, when Su Jinyu went back, Lu Zhewen escorted her two children.

This time is busy, and everyone can come in handy.

If Su Jinyu leaves, there will be at least four fewer people, and there will be three left, and the labor force will be seriously insufficient.

"Isn't there someone in the shadows to protect them, let them help." Yan Yu had thought about this matter a long time ago and felt that there was no problem.

"After all, you're in charge of protection, how are you?" After listening to him, Su Jinyu couldn't help laughing.

"But...... I just remembered that I had been busy for the past few days, and I almost fell asleep when I came back, and I didn't have time to look in the space. ”

Let Yan Yu help him guard it, and Su Jinyu went to the space.

To her surprise, the seeds that had been planted before actually grew!

You know, those new seeds didn't move every time they were planted, and she thought that the new ones were the same.

Hurriedly came to the front, Su Jinyu carefully checked, and all the plants that grew were the same plant, and they smelled a little indescribable.

It's not like something that blooms and bears fruit, it's just a plant.

"What is this?" After staring at it for a long time, Su Jinyu got up to find the answer.

Since it is produced by the first wall, there should be an answer if there is output, otherwise I don't know what it is when I plant it, so how to use it?
