Supreme Pharmacist System Chapter 233: “Cash Crowd”

And when it comes to arsenic, the centipede grass has to be mentioned.

Removing heavy metal pollution such as arsenic and mercury is a problem that has long puzzled scientists.

But then scientists discovered a strange phenomenon: In some arsenic-contaminated land and water bodies, most of the plants have died, but the centipede grass, a fern, is safe.

After testing, scientists found that the 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, the arsenic content of Centipede Grass is 200,000 to 300,000 times higher than that of ordinary plants. It is rich in a large number of toxic substances and is an arsenic-resistant plant.

If the 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 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, there are already scientists working on "cultivating metals".

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

He planted a super-enriched nickel tree in a 50-acre nickel-contaminated area. After cutting the bark, a blue-green liquid would flow out, like gum, and 1/4 of it was nickel. The ore content is high.

The metal is then extracted and purified for sale.

In addition, the smelter also pays him a high environmental management fee.

……

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

The black youth followed, and he pointed to the roots of several needle trees he had cut from the middle and said, "The last time I cut down these shrubs, the sap from them got on my hands, I felt very uncomfortable, and then I went home and soon my hands became like this."

Zhou Wen studied it carefully.

This is a type of shrub known locally as a "needle tree". It is covered with sharp barbs and is very ugly. It is commonly found in rainforest areas.

Don't look at it as a shrub, but its root system is quite developed. It belongs to deep rooted plants. Its main root can penetrate more than 5 meters underground, and some can even reach 10 meters.

So if unsurprisingly, there should be arsenic in the ground, otherwise it doesn't explain areas where hyper-accumulated arsenic plants grow, while other plants are unaffected.

There are more than a dozen needle trees here.

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

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

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

The needle tree is obviously frightened. It is obviously incomprehensible with its IQ. Why can primates understand its language?

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

While collecting samples, Zhou Wen asked, "By the way, is there arsenic ore underground?"

The needle tree does not speak.

Zhou Wen "clicked" and broke a branch.

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

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

The needle tree shivered.

Zhou Wen: "Is there any?"

Needle Tree: "Yes!"

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

After Zhou Wen collected the samples, he turned around and asked, "Where is this 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 trees in the east, where he was poisoned."

"How far is it?"

"A mile or so."

Zhou Wen looked at the sky and said, "Let's go, take me there to see."

Black youths are lazy and unwilling to take him there, including those local people who are unwilling to run away.

Zhou Wen said to the black youth: "Take me there to see, and I will help you heal. I believe you have also gone to the hospital for treatment. This kind of metal local poisoning is difficult to cure. Except for me, No one can cure it!"

The black youth discussed it with everyone.

These people are all close relatives. I heard that Zhou Wen can help young people and old men treat diseases on their hands, and they all agreed.

Zhou Wen led a security guard and followed the crowd into the thorny woods, while the rest stayed where they were to watch over the vehicles.

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

A mile is approximately 1600 meters.

Walked almost an hour through the rough, thorny jungle to get there.

"Hey, it's here." The black young man said, pointing to a dark bush ahead.

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

There are a lot of needle trees here, there are twenty or thirty trees by sight.

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 collected, "Is there arsenic ore underground?"

Without waiting for the needle tree to answer, he first snapped a branch with a "click", causing the needle tree to 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'll show you one first."

Needle Tree: "But I was about 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 returned.

They were out of the woods just before the sun went down.

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, about 6-10 days."

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

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

There is a reason why Zhou Wen is so enthusiastic.

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

The second is the underground arsenic mine.

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. If it is developed, the investment will also be huge.

It's good news anyway.

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

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

……

……

The next morning at nine o'clock.

Lin Gaoxuan waited for an afternoon and an evening, but Zhou Wen didn't take the initiative to come, but Tang Wannian's call came.

"Okay, I see..."

Lin Gaoxuan hung up the phone with a dark face.

The next moment, a head came out of the air-conditioning quilt. It was Shen Yujie, with a peach blossom face and a curly hair on the corner of her mouth. She asked with a charming smile, "How is it, is he coming?"

Lin Gaoxuan secretly hated: "This **** has been abroad for two months, and his brain has been damaged. No matter what anyone says, he will not listen."

Shen Yujie asked, "What should I do?"

Lin Gaoxuan thought about it for a while with a gloomy expression on his face, and finally found that there was no way to get the other party temporarily except to make a phone call himself.

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

The call was quickly connected ~IndoMTL.com~ and Zhou Wen's voice came from inside, "Hello, who is it?"

Lin Gaoxuan sneered and said, "Dr. Zhou is really busy with people. So many people can't help you, and I want to call you personally. You are very good."

Zhou Wen: "Who are you?"

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

Zhou Wen: "Nonsense~ If you don't say it, how can I know who you are?"

Lin Gaoxuan: "...I'm Lin Gaoxuan."

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

"Beep..."
