Chapter 221 Success, but where is my oxygen bottle?!
The entire Mithril District’s dwarves looked at Gretel as if they were a savior. It was he who, risking his own life, rescued Elder Talbot;
It was him who took over the task of the Magic Council to improve the method of mithril smelting;
That is, after he comes, the Magic Council can smelt mithril on its own without Elder Talbot having to work hard to use magic;
It's him who is now standing up and saying, let me think about ways to increase the output of semi-finished products!
Gretel stood up with full confidence...or seemed to be full of confidence. Because the temperature of the fire pool (or furnace, or whatever) was not high enough, Mithril semi-finished products could not be stably produced. For this reason, Gretel
I have already made speculations about this, and have made many plans for this. But these plans...
Grete decided to try it manually first. He put a full set of magic defense on his body, walked carefully five meters away from the fire pool, and took out a tube of potassium permanganate. He lowered his head, concentrated, and adjusted the direction——
Dragon Breath Hand!
Fan-shaped, extremely high-temperature white fire spurted out against the magma, rolling past one meter in front of the old dwarf. The old dwarf quickly picked up the ore, stretched it into the white fire, and shook it gently. In just a moment, it was used to
The long-handled spoon holding the ore burst into flames, the handle of the spoon burned off, and the ore sank into the magma with a "dong" sound...
"Well……"
Gretel quickly stopped casting spells and looked at the old dwarf awkwardly. Old Theon, however, was unusually calm. He leaned over and picked up another long-handled spoon and fished a handful out of the magma. He bent his arm, looked down at it, and nodded with satisfaction.
:
"Not bad, very useful."
He half-turned around, stretched his arms, and handed the product in the spoon to Gretel. The old dwarf's stocky body even slightly bent, and the look he looked at Gretel contained at least 50% respect:
"Your Excellency, thank you for your help. As long as this flame continues to burn, doubling the production of mithril will certainly not be a problem."
Gretel didn't get the meaning of his words at all. A spoonful of half-melted ore was stretched out in front of him, and steam of steam hit his face. Gretel jumped back reflexively and took a few steps back:
Don't come over here!
My [cold and heat resistance] can't even withstand boiling water, and the magic defense on my body can't withstand molten steel!
And, do you think I will stand here for eight hours a day, cosplaying a humanoid fire dragon? I'm not stupid! It's enough to verify that high temperature can help refining ore. The next thing can be done by machines, not by humans.
Come and do it!
Grete nodded to him casually, turned around and walked away. As he walked, he thought: So how to increase the temperature of the furnace? - What kind of furnace is used for making iron? Blast furnace? Open hearth? Converter?
Forgive me that Grete only knows these names, but has no idea what any of them look like. Even if you put the pictures in front of him and ask him to look at them repeatedly, he may not be able to connect them correctly.
What does the inside of the furnace look like? Where does the dye come in, where does the ore come in, where does the oxygen come out, where does the molten iron come out, no, the mithril semi-finished product comes out? Gretel once scribbled it with a pen, and the result was paper
There are seven or eight more messes...
Also, the furnace seems to use refractory bricks. What are the composition and firing method of refractory bricks?
I don’t know, I don’t know, goodbye.
Of course, there are other ways to increase the combustion temperature. For example, add fuel? Add gasoline, add diesel, add kerosene?
Grete doesn't know if there is oil in the world, since he has never seen it.
Burning hydrogen?
It was too dangerous, Gretel didn't want to blow himself up.
Add thermite?
Grete secretly reminded himself to remember to bring over the electrolytic smelting technology later and make some magnesium and aluminum for himself to play with...
Therefore, among all the technical routes, the one that seems most likely to succeed only has two words left:
Blow oxygen.
How much to blow?
have no idea.
What is the oxygen partial pressure? Flow rate? Pressure?
have no idea.
Blow from where?
I don’t know. In Gretel’s mind, there are only two words “blow oxygen” alone.
As for how to blow...
Grete took out a bottle of oxygen - saved during the process of making electrolyzed water - and pulled out his follower from behind:
"Is it possible to move - or blow - the gas in this bottle directly above the fire pool and make it come into contact with the magma?"
"no problem!"
Aurora Wharton was gearing up. He pointed a finger casually, and the mouth of the bottle exploded. Before the oxygen in the bottle could escape—maybe it had escaped, but it was invisible to the naked eye—a translucent force field rolled up and exploded in the magma pool.
A ball of white light.
"That's it!" the braided dwarf shouted, "that's how big the fire is!"
Then, the white light flashed, gone, gone, gone...
Half of the dwarves looked at Gretel, and half of the dwarves looked at Aurora, then followed Aurora's gaze and then looked at Gretel...
Gretel shrugged and took out another bottle of oxygen. This time, the old dwarf at the edge of the fire pool took a posture, his chest rose and fell, and the muscles on his arms stood tall. He turned back to stare at Gretel and nodded heavily:
"Come!"
The second time, he opened the oxygen bottle, cast a spell to transfer the oxygen, and the flames rose. The old dwarf raced against time, shook the ore into the white fire, took it back, looked at it, and sighed:
"No. The burning time is too short. It needs to be doubled at least. Master, is there anything you can do?"
Yes, there is. However, a large amount of oxygen and air flow must be maintained... This is the time to test the industrial strength!
"There is a way! But this requires the support of the parliament - leave it to me and wait!"
Grete turned around and said goodbye. He returned to the Tower of Babel and went to Laboratory 3 on the 375th floor. The laboratory was in a mess. A new group of people had been working on it. The previous sinks, graphite rods, bottles and jars had all disappeared. It was about
The electrolytic smelting has been successful, the project team has been cancelled, and the magicians have gone back to their homes to find their mothers.
Gretel was stunned. He stood at the door of the laboratory for three seconds and let out a scream:
"No! Where are the people! Come back here!"
What are the by-products of the electrolysis process? What is the most efficient way to use magic to evacuate? Separate air at low temperature and high pressure to produce oxygen. Have those magicians got their livers out? At the end of the day, leave two tanks for pure oxygen.
Ah ah ah ah ah!
He turned around in circles at the door of the laboratory, and then in circles, like a melted candle, and squatted down dejectedly. Aurora Wharton quickly came over to pull him:
"Boss, it's okay. I'll take you to find someone. They are all my senior brothers and sisters. I'm familiar with them!"
"Auro," Gretel looked at him with dull eyes:
"Tell me, how come they run so fast? They didn't even write a paper! They could have written several papers just on the separation and measurement of air, so why did they run away???"
"That... that, boss," Aurora scratched her hair:
"Perhaps they are waiting for you to write? After all, it is you who proposed the plan. They cannot write without permission and rob you of the honors and rewards you deserve?"
Gretel: "..."
He later remembered that there is another thing called a corresponding author. The boss is responsible for selecting topics, finding funding, accepting projects, and controlling the overall situation. Under the guidance of the boss, capable researchers are responsible for leading the team and working independently.
.
Of course, such researchers are most likely qualified to be the first author, rather than the second author and third author.
"... Let them write it. After they finish writing it, it's okay to show it to me and I'll be the corresponding author. - What I want now is oxygen! Oxygen!"
As long as my patient can breathe oxygen, and when he has difficulty breathing or during surgery, there is not enough oxygen to breathe, he doesn't care at all about whose name is on those papers.
The project team that was on the verge of dissolution, or in other words, had been disbanded, once again started to move efficiently.
After learning that Gretel had a way to improve the output efficiency of semi-finished products, magicians immediately followed his request and rushed up and down. They built a force field box and filled it with air until it could no longer be filled.
Until you go in. Then, throw [Freezing Ray], [Frost Breath], [Ice Ball], [Northern Wind]...
"Good! It's starting to liquefy! Turn it all into liquid! Then raise the temperature a little bit..."
booooooom!
At the foot of Igor Peak, the stone flat that is exclusive to the Thunder Horn and is specially used for experiments with explosive hazards shook. The next moment, a bright light shone from the Babel Tower, and Carlisle's Grand Master penetrated it.
Mysterious lock, flying down from the peak at high speed:
"What are you doing!"
"Uh... Gretel wants that fire gas. All the ones we made before have been used up..."
Facts have proved that without a great magician above level 13 present, relying solely on force field barriers to liquefy air or something like that is not something you can do casually...
Regardless, Gretel got what he wanted:
Master Carlisle took the lead and took the three highest-level students to cast spells together. Finally, without the blessing of the mage tower, pure oxygen was separated with bare hands;
Another great magician personally took action and created a thick steel cylinder using strong steel mixed with fine gold, which was used to make knight weapons;
After filling, it was sent to the Mithril District. The Alchemy Guild of the School of Change, the great magician responsible for maintaining the magic circle, buried pipes in the wall to blow the oxygen in the cylinder directly to the top of the fire pool.
Oh, by the way, the pipe is still retractable. It can be stretched out when oxygen is blown, and retracted when oxygen is not blown, so as to prevent oxygen from spraying out from the top of the cave, which is too wasteful...
"Mithril ore smelting, the first oxygen blowing experiment, begins!"
Gretel was in the middle giving orders. Aurora Wharton sat in the corner of the mithril forging room, hanging a [Barbarian Power] on herself and holding the rotating valve of the oxygen cylinder with both hands. The Dumfries Master stood in another corner.
Inside, I pressed the button protruding from the pipe on the top of the cave...
The air flow hissed. Soon, the magma rolled around the edge of the fire pool, and the flames turned from gold to white, rising upwards.
"The next step is to experiment again and again to find the right flow rate... The Magic Council replaces the gas bottles at regular intervals and collects the used gas bottles. This is a job that everyone can do. Oh, by the way, you have to be careful.
Don't let the gas cylinder explode..."
Gretel hummed a song and walked out. Not long after, the dwarves burst into heartfelt cheers in the cave behind them.
"Ah, by the way! Where's my oxygen! Leave a bottle of oxygen for me!"
