Chapter 578 To Practice Detoxification, First Go to the Workshop Next Door for a Meal
Serila pouted her lips, with an unhappy face, and threw antidote spells one by one.
Elder Erwin sat cross-legged by the water, resting his fingers on a clump of long grass, closing his eyes and meditating. The grass around me is swaying slightly, and it seems to be communicating with the surrounding nature.
Bernard had nothing to do and had already squatted down to help the miners break rocks.
Apa... I'm very sorry. Gretel's ability to detect emotions can't tell what the expression on Apa's face means.
However, the silver moon deer's body shimmered with light, and the antidote spells were thrown out one by one. The faces of the miners who were treated by him were full of gratitude, and some had tears in their eyes. They had already knelt down to the giant deer.
Obviously, Apa carried everyone this time and became the most powerful healer besides Gretel.
Then, the most difficult task was left to Gretel:
How to teach this targeted detoxification technique - cadmium to the teacher and Cerela?
In other words, how can their detoxification skills be able to identify things like cadmium?
"Grete, can you show me what the cadmium you are talking about looks like? I can't figure it out based on the paper alone!"
Serila threw a circle of detoxification spells and jumped over to ask again. Grete had a bitter look on his face. He supported his right elbow with his left hand, raised his right hand, and rubbed his temples:
"Don't worry, wait until I think about it..."
The easiest way, of course, is to give them a piece of cadmium metal, even a pinch of powder. But it's a pity that Gretel doesn't have this thing in his hands.
Buy from council? Write to the magician who discovered cadmium to buy it? ...It's not that I can't afford it, but it takes at least a week or two to start, and it takes such a long time...
Cerela is going to explode!
So, refine and synthesize it yourself? Extract cadmium from the waste mine in front of you?
How to refine it?
I thought high school chemistry was too difficult and didn’t teach it. In college, I thought inorganic chemistry was too easy and didn’t teach it...
A sideways glance showed that Miss Silver Dragon had not exploded. The silver-haired girl's cheeks were bulging and she stared at him with a little grievance:
"Grete, so that cadmium... what does cadmium look like in the blood? Can you get rid of it together?"
The look in the blood... Gretel thought for a moment and finally understood what Serira was asking. Wait, is it the cadmium element that the detoxification technique removes, or is it the molecules formed by cadmium in the body?
Ah, I remembered it. As for the molecules formed in the body, cadmium combines with substances inside the human body to form metallothionein, or MT for short...
As an emergency surgeon, Grete was impressed by this emergency medicine stuff because a student used "I Am MT" to fill in a song, specifically about metallothionein. It became very popular in the department at that time, and people sang it everywhere.
However, what is the molecular structure of metallothionein, just... Forgive Grete, he is not a big guy in molecular biology, and he really has no idea.
——Wait a minute, when he conducted targeted detoxification, he also directly targeted the cadmium element! I didn’t even consider what would happen to the remaining parts of metallothionein if the cadmium element was removed...
Well, in theory, that protein molecule should denature and then be excreted on its own. Considering that the content of cadmium in the human body is not large, and blood cadmium and urine cadmium are measured in micrograms, denatured protein molecules should not have much impact on the human body.
So the problem is back to the same place. How to lock cadmium element?
——Even if you give me some cadmium oxide or cadmium sulfide!
Gretel frowned and held his chin, squeezing his brains out. A gust of wind blew, and Apa snorted suddenly and came over to give him a hug. Grete was caught off guard and leaned to the side, almost rolling into the stream:
"Appa! What are you doing?"
The Silver Moon Deer grunted and scratched the ground with its hooves. Grete held the stone with one hand and grabbed the antlers with the other, and finally climbed up. What is this for? Work done? Still angry?
He followed Apa's gaze and looked to the side, only to see another puff of yellow smoke coming from the top of the workshop in the distance. It flutters and fills the valley.
It is conceivable that on rainy days or when the airflow is relatively quiet, these smoke and dust will fall to the ground, contaminating the soil and water sources...
No wonder Appa was angry. The high-level monsters in the wilderness possess healing abilities and are instinctively sensitive to the natural environment. With the natural environment ruined like this, Apa probably had the intention of demolishing the workshop——
The premise is that it must clearly recognize that workshops are the main culprit of environmental pollution.
By the way, what does this workshop produce?
For this kind of question, Grete decisively called the person in charge to ask. Although the steward only knows a little bit about it, he can still point out the direction for Gretel:
"It seems like they are making ore ingots... lead ore, zinc ore, etc. By the way, they also seem to be making dyes? Several times when I came back from them, I saw white and yellow powder on the road..."
Hmm... Gretel twirled his chin with his thumb in thought. Lead seems to be a famous dye, and the powder used to paint the face was called "lead powder" in the past. No matter what compound it is, it must contain lead;
As for zinc, zinc oxide is white. One of the powders he used for the sunscreen magic he had been experimenting with before was zinc oxide;
Yellow...what dye is yellow? sulfur? Are there any others?
"Lead the way, let's go take a look." Gretel ordered without hesitation. The steward had a bitter look on his face: "Don't go...it's very dirty over there...it smells bad...just call people over, there's no need to go there..."
"I'd better go and see for myself. There are some things that I can't explain clearly."
Facts have proven that the combination of high-level priest + high-level mage + high-level warcraft is always detrimental.
Grete walked to the door of the workshop with the bubble technique above his head. Before he could stand still, the door of the workshop opened quickly, and a steward wearing a short coat, high leather boots, and shiny buttons on his chest walked out quickly.
"My dear spellcasters, I have come here without warning, but I apologize for not being able to welcome you from afar. My lords, may I ask why you are here..."
"Let's take a look at the products you have here. If they meet our needs, we might buy some."
The workshop manager's expression froze. He really wanted to say, "The goods in our workshop are sold in bulk and not retail." But looking at the people in front of him, he didn't dare to say so. Please, the other party is a high-level spell caster!
Not to mention buying a little, even if you grab a pack, as long as the workshop is not demolished, the boss will probably not do anything... Although he is a warrior himself, he is not even at the level of a knight and cannot be beaten at all...
Gretel easily stepped into the workshop's warehouse. Box after box, bottle after bottle of various products, a dazzling array of products before your eyes:
Lead ingots;
zinc ingots;
Submarine (Grete thinks it should be zinc oxide);
Scattered yellow…
"So what is this?"
Gretel stared at the bottle of yellow powder and tried hard to use his brain. That thing is somewhere between lemon yellow and orange, and sometimes it has a bit of orange, which doesn't look too pure. His intuition told him that this was something related to cadmium, so what exactly was cadmium?
Cadmium oxide?
No, cadmium sulfide!
It's cadmium sulfide!
The light yellow color should be cadmium sulfide, also known as cadmium yellow. It is a widely used dye, mostly used for coloring enamel, glass and ceramics... Yes, that's it!
Gretel stretched out his hand and twisted it a little. Close your eyes slightly, use your mental power to lock the powder in your hand, and use it as a reference to activate the detoxification technique. A slightly yellowish light fell, shining on a young boy who was following them step by step:
"how do you feel?"
The boy burped violently and let out a breath of foul smell. Then, he moved his shoulders, moved his arms, and jumped a few times on the spot, with a face full of surprise:
"It seems much easier! Sir, what have you done?"
Grete smiled but said nothing. He turned around and handed the bottle of cadmium sulfide to Cerela:
"Try it, use this as a reference for casting spells?"
Cerira took it dubiously. Sneak out of the workshop, find a miner, take blood, apply the detoxification spell, and take blood again. The two identification skills fell, and the slender brows frowned tightly:
"Grete, that's not good! The effect is a little bit, but not very good. The cadmium in the blood is just reduced, not completely removed!"
"Emmmm, let me think about it..."
Cadmium is partially bound to metallothionein and partially bound to hemoglobin. So, do we still need to get the cadmium ingots out?
The workshop manager watched her running in and out with a nervous and distressed look on his face. Gretel smiled and threw him a gold coin:
"What, you can't bear to part with it? It's not like we won't pay... Besides, you've also been poisoned. Don't you need me to treat you later?"
When the gold coin was received, the workshop manager breathed a sigh of relief, and then his heart became anxious again. His eyes widened and he opened his mouth to ask. Grete had already pointed to the mine manager next to him:
"You go explain to him about poisoning or something. Well, let me think about how to get this thing out..."
Cadmium yellow... Cadmium yellow... Cadmium sulfide... Cadmium sulfide should be soluble in... soluble in...
By the way, according to its properties, it should be soluble in acid! Cadmium is more stable than zinc, so you can replace it with zinc...
"Bernard! Bring me a table!—Bring me some dilute sulfuric acid, and some zinc!"
Fortunately, these things are available in workshops. Gretel gave the order, and no one else was needed. The workshop manager who confirmed that he was poisoned had already driven the young boy into a frenzy:
"Did you hear that? Hurry up and help Master Mage get something! Dilute sulfuric acid! Zinc ingots! Act quickly! If you keep stalling, I'll fire you! - Master Mage, is such a big zinc ingot enough?... Just a small piece OK? Come on! Get the scissors quickly!"
Cadmium yellow dissolved in dilute sulfuric acid, and a beaker of light yellow solution appeared. Gretel carefully cut the zinc flakes into small pieces, threw them into the beaker, and kept stirring. Amitabha, God bless, God of nature bless, God of war bless...
Give me some cadmium anyway!
The light yellow color in the beaker is getting lighter and lighter. For a long time, among the zinc particles, there were very fine silver-white particles, rustling and falling.
Next, there is extremely boring inorganic chemistry work such as filtration, drying, and pellet pressing. After a long time, Gretel twisted a small handful of dust-like powder and handed it to Cerela:
"Would you like to try this?"
"okay!"
The silver dragon girl ran out happily. Elder Erwin watched silently, speechless for a moment:
Hey, now that I have a girl, I don’t need a teacher anymore?
