Chapter 224 Success, but Where Is My Oxygen Bottle? !

The dwarves in the entire Mithril District 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;

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 now stands up and says, let me think of ways to increase the output of semi-finished products!

Grete stood up with confidence...or seemed to be confident. Because the temperature of the fire pool (or furnace, or whatever) is not high enough, Mithril semi-finished products cannot be stably produced. For this reason, Grete has already guessed, and has made many plans for this. Are they just these plans...

Grete decided to try it manually first. He put a full set of magic defense on his body, carefully walked five meters away from the fire pool, and took out a tube of potassium permanganate. Lower your head, concentrate, adjust direction——

Dragon Breath Hand!

Fan-shaped, extremely high-temperature white fire sprayed out against the magma and rolled 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, the long-handled spoon used to hold 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 Xion was unusually calm. He leaned over and picked up another long-handled spoon and fished a handful out of the magma. He bent his arms, looked down, and nodded with satisfaction:

"Not bad, very useful."

He half-turned around, stretched his arms, and handed the product in the spoon to Grete. The old dwarf's stocky body even bent a little, 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, steaming hot air hit his face. Grete 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, COS the humanoid fire dragon? I'm not stupid! It is enough to verify that high temperature can help refining ore. The next thing can be done by machines, not by humans!

Grete nodded to him casually, turned around and left. As I walked, I thought: So how do I increase the furnace temperature? ——What kind of furnace is used for making iron? blast furnace? Open hearth? Converter?

Forgive me that Gretel 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 fuel come in, where does the ore come in, where does the oxygen come in, where does the molten iron come out, no, where does the mithril semi-finished product come out? Gretel once used a pen to smudge, and as a result, there were seven or eight messes on the paper...

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, bye.

Of course, there are other ways to increase the combustion temperature. Like, fuel? Add gasoline, add diesel, add kerosene?

Gretel didn't know if there was oil in the world. He had 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 partial pressure of oxygen? flow? pressure?

have no idea.

Blow from where?

do not know either. In Gretel's mind, there was only the word "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 Walton is gearing up. He pointed casually, and the mouth of the bottle exploded. Before the oxygen in the bottle could escape—perhaps it had escaped but was invisible to the naked eye—the translucent force field rolled up, and a ball of white light suddenly exploded in the magma pool.

"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...

Grete shrugged and took out another bottle of oxygen. This time, the old dwarf on the edge of the fire pool took a posture, his chest rose and fell, and the muscles on his arms stood high. He turned back to stare at Grete and nodded heavily:

"Come!"

The second time, open the oxygen bottle, cast a spell to transfer oxygen, and the flames rise. The old dwarf raced against time, shook the ore into the white fire, took it back to look at it, and sighed:

"No. The burning time is too short. It must be doubled at least. Mr. Master, is there anything you can do?"

Yes, there is. However, a large amount of oxygen is required and the 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 left. Return to the Tower of Babel and touch Laboratory 3 on the 375th floor. The laboratory was in a mess, and a new group of people had been working. The sinks, graphite rods, bottles and jars before had all disappeared. Probably because the electrolytic smelting has been successful, the project team has been cancelled, and the magicians have gone back to their homes to look for 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 about the by-products of the electrolysis process? How to use magic to vacuum the most efficiently! Use low temperature and high pressure to separate air and produce oxygen. Have those magicians got their livers out? At the end of the day, leave two pure oxygen tanks for me!

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 came over quickly to pull him:

"Boss, it's okay. I'll take you to find someone. They're all my senior brothers and sisters, and I'm familiar with them!"

"Auro," Gretel looked at him with dull eyes:

"Tell me, why do they run so fast? They don't even write a paper! They can write several papers just on the separation and measurement of air. Why did they run away???"

"That...that, boss," Aurora scratched her hair:

"Perhaps they are waiting for you to write? After all, it was you who proposed the plan. They can't write without permission and rob you of the honors and rewards you deserve?"

Gretel: "..."

He later remembered that there was something called a corresponding author. The boss is responsible for determining the topic, 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 to be qualified to be the first author, rather than the second author and third author.

"...Let them write. After they finish writing, it's okay to show it to me. I'll just call you the corresponding author. - What I want now is oxygen! Oxygen!"

As long as my patients can take in oxygen and have enough oxygen to take in when they have difficulty breathing or during surgery, whoever’s name is on those papers will not care about them at all.

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. Build a force field box and fill it with as much air as possible until no more air can be squeezed 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..."

BOOOOOOM!

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 Tower of Babel, and Archmage Carlisle penetrated the mysterious lock and flew 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 really not something you can do casually...

Regardless, Gretel got what he wanted:

Archmage 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's 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 above the fire pool.

Oh, by the way, the pipe is still retractable. It extends when oxygen is blown, and retracts when oxygen is not blown, so as to prevent oxygen from spraying out from the top of the cave, which is too wasteful...

"Mythril ore smelting, the first oxygen blowing experiment, begins!"

Gretel is in the middle and giving the orders. Aurora Wharton sat in the corner of the mithril forging room, hung a [Barbarian Power] on herself, and held the rotating valve of the oxygen cylinder with both hands. Wizard Dumfries stood in another corner and pressed the button protruding from the pipe on the top of the cave...

The air hissed. Soon, the lava rolled around the edge of the fire pool, and the flames turned from gold to white and rose 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 takes back 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 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!"
