Chapter 136 High potassium manganate, the method of making oxygen
The necromancer pulled Gretchen away without any explanation, muttering and complaining all the way. He didn't stop until he entered his tent, dragged out a suitcase from the bedside, and dumped it on 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.
Grete 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. Didn't you go
Being a scout means basically killing people!
"Can't pick one out? Still don't know him?" Seeing Grete's face full of surprise but not taking action, 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, I can't use it, but you should be able to..."
Grete had no time to refuse. He was just thinking about taking 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 is an alchemical material. I don't know how it got mixed 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." Gretel held it up like a baby, looking left and right. The color, shape, and luster were all familiar to him. He had been familiar with them from junior high school to college. When he saw this thing, he
This thing is not stable in nature and easily decomposes. I don’t know which master synthesized it. If it is really potassium permanganate, it can solve 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. When Linn didn't accept it, 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 Gretel's residence. Gretel cleared the table and dragged out the alchemy box. When he turned around, he saw Linn sitting there bored, and simply put it in his hand.
Stuffed a stack of papers:
"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 topics, they were all new ones he had never seen before. He didn’t have time to take a closer look and raised his head and shouted:
"Have you sent it yet?"
"Some are posted, some are not! You take a look first!"
Grete was busy setting up stands, alcohol lamps, and various test tubes and flasks without looking back. Lynn couldn't call him back, so he could only start from the first article "Some records of observing cork, onions, meat and blood using a homemade microscope."
"Started to read. As I read, I felt like a mouse falling into a rice vat, and even Grete's humming voice could no longer be heard.
Grete is indeed humming. He did do the experiment of heating and decomposing potassium permanganate to produce oxygen when he was in middle school. However, the details need to be recalled carefully. And to recall this kind of thing, instead of endorsing it, it is better to hum a song
:
"Fifty-six ethnic groups, raise the valence~~~" No, I sang the wrong words, try again;
"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 alkalis, 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 the skin will be oxidized!"
Oops, I just remembered after humming this sentence! I just took the test tube with my hand...on my hand...the skin on my hand...touched a little potassium permanganate powder! Flush quickly!!!!
Grete hurriedly rinsed his fingers. Fortunately, everything went well in the subsequent experiments. Gas came out of the tube, and soon it was filled with a bottle. Grete lit a small wooden stick and shook it until only a spark was left at the top.
Hold your breath and poke the mouth of the gas bottle:
The fire is bright!
Pure oxygen!
"yeah!"
Gretel cheered. The necromancer raised his head blankly. Gretel smiled and waved to him, then took a small amount of potassium permanganate powder and put it into the test tube. He held the test tube in his hand and held his breath while meditating.
Outline the spell model——
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 he modified it, the air-sifting configuration pointed to the test tube, and at the same time, he added a slight spell configuration to heat the test tube to a certain temperature. Alas, when he improved this magic before, he used mercury oxide to heat and create oxygen, which was very expensive.
, it took a very long time. Fortunately, he found potassium permanganate!
three!
two!
one!
Spark magic!
let's go!
There was a crackle and explosion. The subtle spark technique, which could only ignite paper and dead leaves, exploded on the mud floor in the center of the tent into sparks much brighter than before!
This spark even alarmed the Necromancer. Linn raised his head from the paper, looked at Grete, 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 magic!"
Chew the paper, read the experiment, and then look at the spell model diagram drawn by Grete, try to memorize it, and meditate hard. The spell model is not difficult for Master Lin En, but you need to understand this paper, understand the principle of combustion, and then use the principle to achieve
The idea of a new spell is too difficult. Grete experimented and explained again. After talking all the time, Linn finally understood it.
More than an hour later, the two mages were carried by the barbarians one by one, and 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 Sphere!
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:
