Chapter 137 Potassium Permanganate, a Method of Producing Oxygen (First Update)
Chapter 137: Potassium manganate, a method of producing oxygen (first update)
The necromancer pulled Grete away without any explanation, muttering and complaining all the way. He kept shouting until he entered his tent. He dragged a suitcase from the bedside and threw it onto the table:
"These are my trophies! Come here, see if there is anything you can use, and just take it!"
Under the candlelight, all kinds of rings, necklaces, and amulets were dazzling, making people suspect that he had robbed the jewelry store.
Gretel slowly opened his mouth. He looked at Linn, then at the pile of things on the table, and then at Linn - how many people have you killed? It's been less than a month since the war started. You're not going to be a scout, you're just going to kill people!
"Can't pick one out? Still don't know him?" Seeing Grete's face full of surprise and refusing to do anything, Lin En simply took the initiative to introduce him:
"This ring should have a [cold and heat resistance] stored in it. It's quite useful. I already have one. You can take this;
I don’t recognize this talisman, but looking at the spell circuit above, it should be an offensive spell. You can try it;
This necklace has the power of light, so I can’t use it, but you should be able to..."
Gretel had no time to refuse. He was just thinking about grabbing something casually, even if he accepted the other party's favor, when he glanced at the pile of things, and his heart suddenly jumped:
"Wait!—what is this?"
"This?" Lin En followed his fingertips and saw a bottle of inconspicuous purple-black powder. It flickered slightly under the candlelight, reflecting a bit of metallic luster. He said indifferently:
"Purple scale stone, an alchemical material. I don't know how it got in - it's useless, and it's not easy to put away. It turns into a ball of black ash if you leave it alone. Are you interested? If you want, Take it.”
"I'll take half of it." Grete held it up like a baby, looking left and right. The color, shape, and luster were all familiar to him, and he had always been familiar with them from junior high school to college. When he saw this thing, his instinct shouted four words:
"Potassium permanganate! Potassium permanganate!!!"
This thing is not stable in nature and breaks down easily. I don’t know which god synthesized it. If it was really potassium permanganate, it would have solved a big problem for him.
Gretel asked Linn for a brown bottle, carefully poured half of it in, corked the bottle and handed it back. Seeing that Lin En didn't answer, he forced it into his hand:
"This thing is useful! If it is what I think it is, it will definitely be of great use! Hey, come with me, and after I verify it, I will tell you how to use it!"
Linn followed him out suspiciously, winding all the way back to Grete's own residence. Grete cleared the table and dragged out the alchemy box. When he turned around, he saw Linn sitting there bored, so he simply stuffed a stack of papers into his hand:
"This is the result of my recent research. You look at it first, and by the way, this is a microscope. You also play with it first, and wait for me to do the experiment! I'll call you when I have the results!"
Lin En was caught off guard and was stuffed with a lot of articles. When he flipped through the questions, they were all new ones he had never seen before. Before he could take a closer look, he raised his head and shouted:
"Have you sent it?"
"Some are posted, some are not! You look first!"
Gretel was busy setting up stands, alcohol lamps, and various test tubes and flasks without looking back. Lynn couldn't call him back, so she could only start reading from the first article, "Several Records of Observing Cork, Onions, Meat and Blood with a Homemade Microscope". As I read, I felt like a mouse falling into a rice vat, and even Grete's humming voice could not be heard.
Gretel was indeed humming. He did do the experiment of heating and decomposing potassium permanganate to produce oxygen when he was in middle school, but the details need to be recalled carefully. As for recalling this kind of thing, instead of endorsing it, why not hum a song:
"Fifty-six ethnic groups, raise the valence~~~" No, I sang the wrong words, start over;
"Fifty-six elements, increasing the valence," put down the stand;
"Brothers and sisters of the fifty-six ethnic groups are oxidized." Put down the alcohol lamp and find something to raise it up;
"Fifty-six kinds of acids and bases, put into one sentence," put the sink on the other side of the bracket;
"Potassium permanganate, potassium permanganate, potassium permanganate!" Fill the gas bottle with water, turn it upside down, and put it into the sink.
Hmm, now it's time to heat it up. Grete hummed more and more happily, and the pitch was a little higher:
"Potassium permanganate, a method of producing oxygen," scoop out a little potassium permanganate powder, put it into the test tube, plug it with a cork stopper and a glass tube;
"High potassium manganate, heat the cotton in the fortress," I remember, I put the cotton in first;
"High~~~Potassium manganate, the test tube is slightly downward," no problem, adjust the angle and fix it on the test tube rack;
"High potassium manganate, don't touch the test tube with your hands when doing experiments, otherwise your skin will be oxidized!"
Oops, I just remembered after humming this sentence! I just took the test tube with my hand...and the skin on my hand...touched a little potassium permanganate powder! Flush quickly! ! ! !
Grete was hurriedly rinsing his fingers. Fortunately, everything went well in the subsequent experiments. Gas came out of the tube, and soon a bottle was filled. Grete lit a small wooden stick and threw it until there was only a spark at the top. He held his breath and poked the mouth of the gas bottle:
The fire is bright!
Pure oxygen!
"yeah!"
Grete cheered. The necromancer raised his head blankly, and Grete waved to him with a smile, then took a small amount of potassium permanganate powder and put it into the test tube. He holds the test tube in his hand, holds his breath and concentrates, sketching the spell model in meditation——
In every fire magic, there are two basic configurations: one is used to gather "phlogiston", and the other is used to filter "good air" that can attract phlogiston.
After his modification, the air-sifting configuration was pointed at the test tube, and a slight spell configuration was added to heat the test tube to a certain temperature. Hey, when he improved this magic before, he used mercury oxide to heat to create oxygen, which was very expensive and took a long time. Fortunately, he found potassium permanganate!
three!
two!
one!
Spark magic!
let's go!
There was a crackling explosion. The subtle spark technique, which could only ignite paper and dead leaves, exploded on the mud floor in the center of the tent with sparks much brighter than before!
This spark even alarmed the Necromancer. Linn looked up from his paper, looked at Gretel, and asked him what happened with his eyes. Grete came over with a happy smile:
"I have improved a magic! Let me tell you about it! - Hey, you first read the article "Using Heated Mercury to Demonstrate the Nature of Combustion"! Look! Look! After reading it, I will tell you how to use the magic!"
Chewing papers, reading experiments, and then looking at the spell model diagrams drawn by Gretel, trying to memorize and meditate. The spell model is not difficult for Master Lin En, but it is too difficult to understand this paper, understand the principles of burning, and then use the principles to arrive at new spell ideas. Gretel was experimenting and explaining again, and when he was all done talking, Linn finally understood a little bit.
More than an hour later, the two mages were carried by the barbarians one by one. They slipped out of the military camp like the wind and went far outside the camp to test their magic.
Spark magic!
Extremely bright sparks.
Burning Hands!
A blazing white, far more intense cone-shaped pillar of fire.
Blazing ball!
The burning fireball flew far away, and the power of the explosion in the air caught up with the higher-level fireball technique!
Master Lin En stared at the fireball, dumbfounded. When he was finally able to speak, every syllable he spoke was trembling slightly:
"Gretel, you...do you know what you gave me?!"
