Only one night later, not even one night, Wang Qian's emotionless voice sounded outside the door. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Under the service of Lao Zhong, he put on his clothes and didn't even have time to eat, Feng Zhidai's horse face appeared in front of him.

"I said chestnut, can you hurry up? I've been waiting for you for almost half an hour, and my dad said we have to get the finished salt out today, or you'll clean me up! ”

"Cleaning you up, isn't it about me and my?" Zhang Yi was holding the willow branch and the snow-white salt at the same time, and he didn't pay attention to the distressed Wang Qian's gaze on the side, brushing his teeth, and after brushing his teeth, he cleaned his mouth with water before he arrived: "Besides, isn't it just to get some salt?" Mere trifle! Wait for buddy to eat first! ”

Wang Qian's face immediately darkened, a pair of huge fists were bruised, he was already trying his best to suppress his emotions, if it wasn't for Feng An's explanation, he really had the urge to pull away this lazy thing in front of him! It's already an hour, and the sun is about to come out in front of him, and he's still grinding, doesn't this kid know how much more salt he can boil out a minute earlier?

Slowly drank a bowl of gruel, as for the next meal, he didn't move, a large ball of boiled vegetable dumplings sprinkled with a few grains of salt was disgusting at first glance, compared to the kimchi he made in Haifeng, it was simply a heaven and an earth.

When the group came to the beach, there was already a large group of government soldiers sitting in groups of three or five waiting.

"Second son, Wang Xiaowei ....."

One by one, the veterans straightened up and saluted respectfully, and then waited for the order.

Looking at the cauldron propped up next to him and the pile of items listed last night, Zhang Yi nodded. Without a hint of discount, the vat is definitely big enough to be smashed even if Sima Guang picks up a stone, and there is also linen, and a whole dozen horses are neatly put aside, and even the wood of the branch jar is freshly cut cypress, which shows that both Feng Ang and Wang Qian attach importance to this matter.

"Look at the process, I'll just do it once and then you'll do it." Zhang Yi beckoned two sturdy veterans to help, first hoisted the large vat on a stand made of cypress, and then instructed them to make a small hole in the bottom of the vat.

"Okay, why do you make a hole?" Feng Zhidai was very disdainful when he saw Zhang Yi's loser's behavior, and although he didn't stop it, he still muttered out.

"Do you understand filtering? It is to filter out the impurities in the seawater! .....”

After talking endlessly, looking at the blank looks of everyone in front of him, Zhang Yi felt that his words were in vain. He now felt that the saying, 'The people can make it, but they can't know it!' How true that is, because it's really hard to explain it to them.

When you tell them that they make a hole in the bottom of the tank so that the sea water can flow out of it, they will ask you why you don't just scoop the water into the iron pot..... Zhang Yi wondered, if he could directly scoop seawater into the pot and boil salt, he would still use it to teach himself?

Ignoring these uneducated fellows, after seeing that the veteran had opened a small hole under the tank according to his own requirements, he spread the sackcloth in the inner and outer three layers of the tank, and then 'popped the cleaned pebbles!' After pouring into the half of the jar, the burlap began to spread, and at last the whole jar was only the top of the jar, and there was a little space left for pouring water into it.

"Make a stone ladder suitable for you to go up and pour water here, and then you will add water to this place on the stone ladder!" Zhang Yi gestured while beckoning the rest of the people to follow his practice to erect a few more of these vats next to him.

There are a lot of impurities in seawater, and just preliminary filtration can not meet the requirements of direct consumption, what he has to do now is to filter it several times to achieve the best filtration effect under limited conditions.

Just made a sample, Zhang Yi was tired, it was really not a physical work, seeing the veterans one by one still energetically busy Zhang Yi felt that he should repair his body in the next few days, if according to the current situation for a long time, he estimated that it would not be long before he would become a waste of meat.

In less than half an hour, the five large vats were propped up, all of which were paved with stone and linen cloth with reference to Zhang Yi's template.

"Can it be done?" Feng Zhidai watched the veteran keep pouring seawater from one tank, and then took the bucket to catch it and walked towards the other tank, and after several repetitions, his heart became more and more bottomless.

In his opinion, this is not salt making at all, but a child's house, if he hadn't seen the snowflake salt taken out by Zhang Yi earlier, he probably wouldn't have doubted it, but affirmed it.

Not only him, but Wang Qian, even the veterans who worked felt unreliable, and they could make snow-white salt by pouring the seawater around?

"What do you think?" Zhang Yi smiled at Feng Zhidai, then squatted down and lit the firewood under the iron pot, and said: "There are some things that you look simple, but in fact, there is a lot of knowledge in them, and with your current wisdom, you can't understand this, just like the filter I just told you, you don't know what the purpose of doing this is!"

For them, I just need to tell them what to do, but you must know that the reason why I constantly filter the seawater is to remove the things we don't need, and the last thing I keep is the seawater with a lot of salt, and after steaming, we can get the salt we need!

Of course, even our repeated filtration is actually only edible, and it is still a long way from becoming the purest salt! ”

Can't explain too much to Feng Zhidai, if he explains too much, he needs to add chemical knowledge to it, so that the little knowledge he has can not only not help him, but it is very likely that he will get into the horns of the bull, and from then on, he will not be able to protect himself and become a fool.

As for Wang Qian, it is much simpler, since Zhang Yi dares to do this, in his opinion, he is absolutely 100% sure, in addition to staring at Zhang Yi's every process without blinking, he even sent out a team of people to be vigilant, if there is the guy who eats the leopard's gall dares to peek at the side, I believe that Changdao in the hands of those veterans will definitely cut off those people's heads without hesitation.

The seawater gradually turned from grayish white to colorless under the continuous filtration, and then it was poured into the iron pot, watching the solution tumble and bubbling in the pot Zhang Yi finally had time to rest, all he had to do now was to wait, and after the water was completely evaporated, something would be revealed that surprised everyone.
