It's not that hard to open a hospital in another world, right?

Chapter 580 Eat fish grown in cadmium water, entertain benefactors~~~
The green tide surged and filled the valley.

The weeds are growing up like crazy.Floods over roads, shades houses, swallows water.In one moment, it overflows the head, in the next moment, the roots climb, and in the next moment, more plants emerge spontaneously.

In the blink of an eye, the appearance of the small village was not much different from the villages Gretel had seen in his previous life, where the villagers moved away and only houses remained.

In the distance, the exclamations and shouts of the villagers came with the wind.

In Gretel's mind, this green storm seemed to last for 10,000 years, and it seemed that it only lasted for a moment.After a long time, he leaned back, spread his limbs, and lay on the grass.The thin clothes were completely soaked in sweat.

He lay with his eyes closed for a long time, finally gathering some strength, and looked at the gray clouds in the sky:

"Teacher, I can only do this—"

Restoring soil pollution is an extremely difficult and lengthy process.As far as Gretel knows, the methods used in the previous life, but without exception, the cost is extremely high, and the effect is extremely slow...

And most of the time he can't.For example, what kind of foreign soil/replacing soil method, rinsing method, curing and stabilization method, electric repair method, and the like——

Soil replacement method, not so much soil;
The leaching method only washes the heavy metals on the surface into the groundwater, and it will also cause groundwater pollution;
Electric repair method, firstly, Gretel can't prepare such a large amount of electrolyte, secondly, he doesn't know how much voltage to pass through, and he can't generate electricity with bare hands like the teacher;
For the solidification and stabilization method, forgive him for only knowing about adding chemical substances to the soil, what to add specifically, sorry, goodbye.

Only phytoremediation can barely try.At any rate, he was a spellcaster of the natural department, so it was still possible to spawn weeds.

He lay still, but Elder Elwin was walking in the grass, identifying one by one.Recognize one tree, talk to Apa when you turn back, recognize another tree, and talk to Apa when you turn back...

Finally, with the help of Apa, Elder Erwin grabbed a plant with small white flowers that was one foot high and came over.Well, this thing consumes less magic power, and the effect of accumulating pollution is particularly good——

Mainly Appa said it was "extra strong in flavor".Bring it to Gretel and start teaching the students:
"Well, this Arabidopsis thaliana consumes less magic power, and the effect of accumulating pollution is particularly good. And it can grow for many years, grow a crop, cut it off, and grow another crop...Grete, remember, I will repair the lead and zinc later. Mine pollution, it is the most convenient to use, and its brothers and sisters can also..."

Gretel rolled half a circle on the ground with difficulty, looked up at the grass, and groaned in pain.

These things, they recognize me, I don't recognize them, what should I do?
But you have to remember it.Phytoremediation does not work overnight. It does not mean that the heavy metals in the soil can be removed by growing these plants once.

It takes many springs and autumns for plants to grow over and over again, enriching heavy metals, being recycled and treated, so that the heavy metals in the soil can gradually disappear.This time the spell can only be reduced a little bit.

"Grete, what to do with the grass?"

Gretel glanced at the long grass that had just been born, and wanted to hug his head and groan.You don't need to have studied soil restoration to know that these grasses cannot be allowed to wither and rot in place, otherwise heavy metals come from the soil and return to the soil.

But let him kill all the grass?

"Uh, in theory, they should all be recycled, carbonized, and then the metals should be extracted... It is possible to use the drying technique, but..."

It's not impossible, but just after they were spawned, they were killed with spells. Just thinking about that scene, Gretel felt a dull pain in his stomach.

And more difficulties are ensuing.In the distance, the shouts and cries of the villagers and miners spread along the road:

"My lord pastor! Our fields, fields, are all overgrown with weeds..."

"Master pastor, the road down from the mining area is overgrown with weeds, and the ore is not easy to transport..."

Oh.

If it's full, it's full.

Anyway, the food, vegetables, and all products grown on this land are inedible, and heavy metals will continue to accumulate after eating.As for the roads in the mining area, it's a big deal to mow the grass...

Mowing the lawn...

Gretel calmly took out a gold coin.After thinking about it, he put it back and took out two silver coins:

"Well, I'll hire you to mow the grass. One load of grass in this valley costs two copper coins, and five loads costs one silver coin. After cutting all the grass, the money you earn is enough for you to buy grain for a year. How about it? "

Two coppers bought a pound of flour, or a loaf of baked bread.If you use it to buy unground wheat, you can buy more.A strong laborer can mow a few loads of grass a day with ease.

Gretel crossed her hands happily.

Let someone else cut it, and I'm only responsible for carbonization—or seal the furnace and burn it directly.Hmm, the gentleman is far away from the kitchen, as long as I didn't kill it, I didn't kill it...

With a wave of his hand, the mountains and plains are full of weeds.Looking at the amount, it is not a problem at all to give enough money for food for a year.

Elder Erwin smiled and added:
"I will pay you on the spot for the grass cut today. In the next few days, I will call a pastor of the God of Nature to come and count the haystacks. Is that okay?"

That's great!The priests of the God of Nature have always had a good reputation among the poor. They are responsible for distributing money, and absolutely no one is worried about embezzlement of money!
The villagers went back with gratitude.Soon, there was cheering, and all the villagers who were free and able to move around tried their best to rush out.

You can't mow the grass, but you can still pull the grass!

Elder Erwin smiled and nodded to his disciples.Good job, ruined their fields, but did a good thing!
For the money, Gretel stayed another night in the village.Men, women, old and young went to battle together, and the miners also put down their work and worked hard.

By the time it was dark, the valley had been bald, and on the threshing ground at the entrance of the village, the weeds were so piled up that it was almost impossible to get down.And Gretel sent out dozens of silver coins!
rich!
Got money to buy food!

This winter and next spring, you won’t be hungry anymore!

If you work hard for a few more days and clean up the entire valley, you can save money to make some clothes, and maybe even repair the leaky roof!

Cheers came and went.Gretel walked slowly on the threshing floor with a smile, throwing spells casually:

Dehydration!
Dehydration!
Dehydration!
"By the way, do me a favor, sweep up all the soot!"

The villagers scrambled to rush out.Elder Erwin noted:
"What do you want these for?"

"Take it back and refine it!" Gretel said confidently:

"About the toxicity of cadmium to the human body, soil pollution, and treatment, use it as an experiment and publish an article! I have spent so much money, I have to find a way to earn some back!"

However, for the villagers, they don't understand what to do experiments, what to publish articles, and what to ask for rewards from the Magic Council after publishing articles.What they saw was only Gretel and his party working hard to treat the people here one by one;

In order to restore the water and soil here, a large-scale spell was also launched, which gave birth to plants in the entire valley;

Worried that they have no food to survive the winter, use mowing grass as an excuse to hire, send them money...

Good man!
The priests of the deity sect, one by one, are all extremely good people!

Since they are good people who help them, the villagers naturally have to do their best.It is rare for these pastors to stay overnight again. If you have any good things, take them out!

That night, under the dim oil lamp, Gretel saw wooden bowls, wooden dishes, wooden basins, and seven or eight dishes piled up on the table.There are green and green wild vegetables, which look like they have only been blanched in water, without any oil or salt;
Dried meat with an extremely suspicious color, probably smoked, and the carcinogen content is estimated to be very scary;
There was a fish caught in the afternoon. Gretel didn’t even need to dissect it, but he saw that its spine was bent, its ossification was not complete, and it looked like “I’ve already accumulated countless times of cadmium, and I’m already terminally ill”...

Can these things be eaten?
Gretel seems to remember that the concentration of heavy metal pollution in animals seems to increase exponentially compared to that in plants... How many times is it? 10 to the 3rd power, 4th power, or 5th power?

Eating it by yourself is a bit overwhelming; letting the villagers eat it, these things have accumulated a lot of toxins!No matter what I do, my conscience hurts...

He glanced at Elder Erwin. Elder Erwin didn't change his face. He picked it up and ate it. He was obviously used to the villagers' thanks;
Look at Cerilla, who looked bored and walked out of the house directly. Although the villagers looked regretful, they were not surprised. They obviously felt that "Missy should be picky";
Looking at Apa again, Apa has already started grazing grass, while eating, the white light on his body is shining slightly, obviously throwing detoxification on himself.

You, you are ruthless!
Well, cadmium accumulates mainly in the liver, kidney and bones. If you eat fish, you don’t eat these three anyway, and the accumulation of toxins in the muscles is still relatively small...

Besides, there is no detoxification technique!
eat!
Gretel forced himself to try to fill his stomach.By day two, he was thankful for his choice:

The food of the villagers was unpalatable, and the feast of the city lord was even more unpalatable!

"So it's completely cured this time, right? The strange disease won't reappear, right?"

The city lord Joan delivered a speech of gratitude, raised his glass, and asked seriously.Gretel looked at the veal, foie gras, and fried cod in front of him, and couldn't eat for a moment.

"There will be again. There will definitely be again. Five years, ten years, 15 years... Only that lead-zinc mine has been open, as long as that workshop has been open, toxins will continue to accumulate in the soil and water, and strange diseases What, there will definitely be more.”

He looked eagerly at the city lord:

"That workshop, can it be strengthened a little bit of protection, don't drain the waste water directly into the soil?"

"how is this possible!"
