I don't want to be a saint

Chapter 176 Can also filter arsenic?

In order to confirm the conjecture in his heart, Guo Yi couldn't wait to walk towards the sand dunes.

Jiang Yan yelled: "Erlang, drink some tea first to relieve fatigue!"

"No! I'll talk about it when I get back." He replied without looking back.

Seeing his appearance, Jiang Xu couldn't help following him curiously: "Erlang, what are you going to do?"

"Go and confirm my conjecture!"

guess?

Funny!Jiang Xu muttered something, but the movements of his feet were not slow, so he quickly followed.

The entire sand dune is a continuous piece, ups and downs, and the end can't be seen at a glance.And it was barren, with only a few very sparse weeds.

Due to years of wind and sun, the upper layer of the sand dunes is already very loose, and as long as the wind blows, it will be full of wind and sand.

But at this time, it was calm and windless, only the scorching sun was shining all over the sky.

I saw that on the sand dunes, a layer of white matter appeared occasionally, somewhat like frost and snow in late autumn.Moreover, there are many animal footprints in the distance.

really…

You know, the sand dunes are very barren, and there are not many weeds to eat.Then these animals come here for only one purpose, to eat salt!

Like humans, they also need a certain amount of salt intake.

He found a piece of sand and stone, and opened the flying sand on it, took some powder from the sand and stone with great effort, and put it into his mouth without hesitation.

Bitter...salty...astringent, and some strange flavors.

And Jiang Xu, who was next to him, saw his movements and couldn't help imitating him out of curiosity. He took some powder and put it in his mouth.

Phew... poof... vomit... cough cough cough cough

"It's so bitter!" Jiang Xu kept spitting there.However, seeing that Guo Yi didn't spit it out, he was still savoring it carefully.

So, unwilling to admit defeat, he buckled some more, hesitated for a while, and put it in his mouth.

"Toxic!" Guo Yi kindly reminded.

scare!
Jiang Xuxuan was so scared that he didn't die, so he quickly vomited: "Bah, bah, bah! Puff...poof"

"Let's put it down, just that amount, it won't kill anyone! I won't eat it either!"

Uh... Only then did Jiang Xu realize that he had been cheated on, so he couldn't help but glared at him viciously.

"Let's go, go drink tea and take a rest!" Guo Yi said, clapped his hands, and went back the same way.

Seeing him going down the mountain, Jiang Yan couldn't help asking curiously: "Can Erlang get anything?" As he spoke, he handed over a bowl of tea.

"Yes!" Guo Yi nodded and said, "This is a good place! Not only is there brine underground, but the sand dunes above also contain salt, and the content is not low!"

Salt in the dunes?
Jiang Yan was very puzzled when he heard this.I can't help but turn my head to look, these sand dunes seem to be no different from ordinary soil dunes?

It looks like they are all mounds, and they are everywhere when the wind blows.He looked at it for a long time, but he didn't see that he was ugly and Yinmao.

Simply, he stopped thinking too much and asked Guo Yi what he thought: "What does Erlang mean?"

"Do an experiment first, and if it works, we'll do both!"

The sand must be ground into powder first, and then a simple filter device should be made to filter out the toxic substances.

Fortunately, Jiang Yan was very considerate and recruited not only masons, but also several carpenters.

The filtering device is very simple. Find a few earthen jars, and open a hole under the earthen jars, fill them with coarse sand and fine sand in turn, and put charcoal in the last two earthen jars.

When finished, stack them one by one.

Then, pour the sand that has been ground into powder into water to dilute it.You get mixed brine.

It is not as pure as underground brine. After all, underground brine is a few meters or more than ten meters deep underground, and it is very pure after being filtered by layers of soil.

Next, pour the diluted miscellaneous salt brine into the filter device, flow through coarse sand, fine sand, and charcoal from top to bottom in sequence, and drip into the wooden barrel below.

Jiang Xu squatted aside, watched patiently, and asked curious questions from time to time.

While doing it, Guo Yi explained to him: "This is the simplest filter device, which can filter out the toxic substances in the brine, leaving only relatively pure brine.

When you can't find clean water in the wild, you can also use this method to pour dirty water in to get clean water. "

"Can also filter arsenic?"

Uh... Guo Yi couldn't help but have black lines all over his head, so he shook his head and said, "I haven't tried it! If you are interested, you might as well give it a try!"

This kid is too out of his mind.

And Jiang Yan was behind him, slapped his eldest son on the head, and scolded: "Don't talk nonsense! What kind of arsenic is not arsenic, that's something you can play with?"

Guo Yi raised the corner of his mouth and said leisurely: "It is a good thing to have the spirit of exploration!"

"Stop talking nonsense!" Jiang Yan glared at him angrily.

At this moment, Chen Guangming came over from a distance and shouted loudly, "Erlang, in your opinion, how should this salt farm be built?"

He is the steward of the Liuzhihe Saltworks, so he was dispatched here, so naturally he also came as the steward.

That being the case, he has to take up his airs and responsibilities in managing affairs.He is very open about this.

When Guo Yi heard this, he couldn't help standing up, handed over the task of filtering the brine to Jiang Xu, and walked towards Chen Guangming.

However, Jiang Xu did not accept this task, and directly spoke to his father, stood up, and followed closely behind him.

"Is there a river here?"

When Chen Guangming heard it, he was a little confused and shook his head: "I don't know! I'm not a local!"

After finishing speaking, he suddenly came to his senses and greeted a local person loudly: "Old Lu, you bastards, is there a river nearby?"

river?
The visitor shook his head: "No! The nearest river is twenty miles away!"

After finishing speaking, he raised his finger and pointed: "Go straight west from here, go straight for about ten miles, and then go south for a few miles, and you will reach Bashui! It is a big river!"

Bashui is an important branch of Dajiang.When passing Jinghu North Road for the first time, it separated from Dajiang and turned south. After making a big circle on Jinghu North Road, it continued to flow eastward.

When Guo Yi heard this, he couldn't help being very distressed. Without rivers, waterwheels cannot be used, and without waterwheels, there are no water quilts and water mills.

If purely using manpower to grind sand and gravel, what is the labor cost?

Moreover, being far away from the river also means lack of domestic water, which is a big problem for people to eat horse chews every day.

You know, the ground is full of brine.I don't know where to go.

Hemp egg!

No wonder humans have always lived along rivers since ancient times.It's like Tokyo City in the Zhou Dynasty, just beside the Yellow River.

But what you need to know is that the banks of the Yellow River are higher than the city walls of Tokyo.

Once the Yellow River breaks its banks, it will flood Tokyo.A vast ocean flooded the country.

Historically, the city of Tokyo has been flooded several times.

But that's the case, Tokyo City has never moved...

well!Do not move!
