Supreme Pharmacist System

When it comes to arsenic, we have to mention centipede grass.

Removing heavy metal pollution such as arsenic and mercury has been a problem that has plagued scientists for a long time.

But later scientists discovered a strange phenomenon: in some land and water bodies with serious arsenic pollution, most of the plants had died, but the fern such as centipede grass was safe and sound.

After testing, scientists found that centipede grass not only has a strong super-adsorption capacity for arsenic, but also has a certain effect on the adsorption of other heavy metals.

After testing, Centipede Grass is 200,000 to 300,000 times more arsenic than ordinary plants, and it is a plant that is resistant to arsenic poisoning.

If centipede grass is used to extract heavy metal pollutants such as arsenic in the soil, and then harvested and incinerated, the amount of toxic waste gas will be greatly reduced, and the ash after incineration can also be turned into mineral resources for smelting.

Under ideal conditions, the arsenic content in plants can be as high as about 20%, which is equivalent to a mineral resource.

And as far as Zhou Wen knows, some scientists are already researching "farming metals".

Alan Baker, a botanist at the University of Melbourne, for example, is practicing this model.

He planted super-rich nickel trees in the 50-acre nickel ore-contaminated area. After cutting the bark, a blue-green liquid will flow out, like gum, and 1/4 of it is nickel, which is more than the ore content of the nickel smelter. high.

The metal is then extracted and purified for sale.

In addition, the smelter has to pay him a high environmental management fee.

...

Zhou Wen stepped forward to check those hyper-accumulated arsenic plants.

The black young man followed, pointing to the roots of some needle trees that he had cut off from the middle, and said: "When I felled these bushes last time, the sap on them stained my hands, and I felt very uncomfortable at that time, and then I went back to I went home, and soon my hands became like this."

Zhou Wen studied it carefully.

This is a kind of shrub plant called "needle tree" in the local area. It is covered with sharp barbs and is very ugly. It generally grows in rainforest areas.

Although it is a shrub, its root system is quite developed. It is a deep-rooted plant. Its main root can penetrate more than 5 meters underground.

Some even can reach 10 meters.

So if it is as expected, there should be arsenic mines underground, otherwise it cannot explain the area where hyper-accumulated arsenic plants grow, but other plants are not affected.

There are more than a dozen needle trees here.

Zhou Wen and the bodyguard asked for a dagger, and cut a knife on the stem of the needle tree.

Needle tree: "Knock you...it hurts me to death."

Zhou Wen: "Shut up, I'm collecting samples!"

The needle tree was obviously frightened, and it obviously couldn't understand it with its IQ. Why can primates understand its language?

And at this moment, a milky white liquid flowed out from its cut stalk, and fell to the ground with a "tick-tick".

While collecting samples, Zhou Wen asked, "By the way, are there arsenic mines underground?"

The needle tree does not speak.

With a "click", Zhou Wen broke a branch.

Needle tree: "Knock you...it hurts me to death."

Zhou Wen: "Is there an arsenic mine underground? If you don't say anything, I'll uproot you later."

The needle tree trembled.

Zhou Wen: "Is there any?"

Needle Tree: "Yes!"

Zhou Wen: "Then I won't pull you out today."

After Zhou Wen collected the samples, he turned around and asked, "Where is there such a similar plant?"

The old black man with moderate arsenic poisoning pointed to the east side and said a few words, and the young black man translated: "He said that there are still in the woods in the east, and he was poisoned there."

"How far is it?"

"A mile or so."

Zhou Wen looked at the sky, and before he had time, he said, "Go, take me to have a look."

Black young people are lazy and don't want to take him to see it, including those locals who don't want to run away.

Zhou Wen said to the black youth: "You take me there to have a look, and I will help you heal your hands later. I believe you have also gone to the hospital for treatment. This kind of local metal poisoning is difficult to cure. No one can cure it except me. cured!"

The black youth discussed with everyone.

These people were all relatives, and they all agreed when they heard that Zhou Wen could help young people and old men treat their diseases.

Zhou Wen led a security guard and followed the crowd towards the thorny woods, while the rest stayed where they were and took care of the vehicles.

There is a small road here. According to the black youth who led the way, it was stepped on by the South Africans who came to their village to steal baobab trees, and this place belongs to the territory of Botswana.

One mile is about 1600 meters.

It took nearly an hour to get to the place after walking in the rough and thorny jungle.

"Hey, it's here." The black youth pointed to a dark bush in front of him and said.

Zhou Wen stepped forward to take a look, and it was true.

There are many needle trees here, and there are twenty or thirty trees by visual inspection.

Zhou Wen collected samples in turn from several of the thickest needle trees.

Of course, I was scolded by the tree every time.

Zhou Wen asked the same question to the last needle tree he collected, "Is there arsenic mine underground?"

Without waiting for the needle tree to reply, he broke a branch with a "click", which made the needle tree squeak and scream in pain.

Needle Tree: "Why did you break my hand?"

Zhou Wen: "Kill the chicken to warn the monkey, do you understand? I'm afraid you won't tell me, so I broke one for you to see."

Needle Tree: "But I'm going to tell you."

Zhou Wen: "...I'm sorry."

The needle tree was sad for a while... Zhou Wen could feel its sadness, a very obscure plant language.

Then the oldest needle tree told Zhou Wen that there were rich arsenic mines under its feet.

Zhou Wen thanked it, and then returned.

Before the sun went down, they came out of the dense forest.

Zhou Wen used a biological antidote to detoxify two people who had been poisoned by arsenic.

"Because this is heavy metal poisoning, it needs a recovery period, maybe 6-10 days."

The black youth moved his palms and said happily, "I feel much better."

Zhou Wen nodded and handed over a business card, "That's good! This is my business card. If you have any questions later, just call me."

Zhou Wen was so enthusiastic, of course, for a reason.

The first is the super-enriched arsenic needle tree, which is very rare, and its root system is so developed that it can be called a "cash cow" whether it is used to control heavy metal pollution or to extract underground arsenic mines.

The second is the underground arsenic mines.

Arsenic is very valuable. The market price of 6N is about 1,000 yuan/kg, and the market price of 7N is about 2,000 yuan/kg.

Of course, this is also very polluting to the environment, and if it is developed, the investment will be huge.

But it's good news anyway.

Because of this, it is necessary to establish a good relationship with these locals in advance to facilitate some operations later.

After eating a distinctive local dinner, Zhou Wen and the others rushed to the hotel in the city to rest overnight.

...

...

Nine o'clock the next morning.

Lin Gaoxuan waited all afternoon and one night, but Zhou Wen didn't take the initiative to come over, but Tang Wannian called.

"Okay, I see..."

Lin Gaoxuan hung up the phone with a dark face.

The next moment, a head popped out of the air conditioner. It was Shen Yujie, with peach blossoms on her face and a curly hair sticking to the corner of her mouth. She asked with a charming smile, "How is it? Is he coming?"

Lin Gaoxuan said bitterly: "This bastard, who has been abroad for two months, has spoiled his brain, no matter what anyone says."

Shen Yujie asked: "Then what should I do?"

Lin Gaoxuan thought about it for a while with a cloudy expression, and finally found that there was no way to take the other party for the time being except for making a phone call himself.

"Let him be proud for a while, and see how I deal with him when I return to the country!" Lin Gaoxuan pressed Shen Yujie's head into the bed, took out his phone and dialed a number.

The phone was connected quickly, and Zhou Wen's voice came from inside, "Hi, hello, who is it?"

Lin Gaoxuan sneered and said: "Dr. Zhou is really busy with work, so many people can't invite you, and you want me to call you in person, you are awesome."

Zhou Wen: "Who are you?"

Lin Gaoxuan felt that this was the point of what he had said. It was impossible for the other party not to know who he was, and it was clearly intentional. He said coldly, "You really don't know who I am?"

Zhou Wen: "Nonsense~ If you don't tell me, how would I know who you are?"

Lin Gaoxuan: "...I am Lin Gaoxuan."

Zhou Wen: "I don't know! You made a mistake."

"Beep beep..."
