It's not that hard to open a hospital in another world, right?

Chapter 224 Success, but what about my oxygen cylinder? !

The dwarves in the entire Mithril District looked at Gretel with the eyes of a savior.It was he who, regardless of his own life, rescued Elder Tarbert;
It was him who accepted the task of the Magic Council to improve the method of mithril smelting;

That is, after he has been here, the Magic Council can smelt Mithril by itself, without the need for Elder Tarbert to work hard to use divine magic;
It is him who now stands up and says, let me think about the way to increase the output of semi-finished products!
Gretel stepped forward confidently...or seemed confident.Because the temperature of the fire pool (or furnace, or whatever) is not high enough, it is impossible to produce Mithril semi-finished products stably. For this reason, Gretel has long guessed and made many plans for this.But these plans...

Gretel decided to try it manually first.He hung a full set of magical defenses on his body, walked five meters away from the fire pool carefully, and took out a tube of potassium permanganate.Bow your head, concentrate, and adjust your direction——

The hand of dragon's breath!

Fan-shaped, extremely high-temperature white fire sticks to the magma, jets out, and rolls one meter away 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 an instant, the long-handled spoon used to hold the ore burst into flames, and the handle of the spoon was burned directly, and the ore sank into the magma with a "gudong"...

"Uh……"

Gretel quickly stopped casting spells and looked at the old dwarf in embarrassment.Old Theon was unusually calm, leaned over and picked up a ladle again, and scooped a handful from the magma.Bend your arms, look down, and nod 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 bent a little bit, and at least 50% of the respect was contained in Gretel's eyes:
"Your Excellency, thank you for your help. As long as this kind of flame continues to burn, it will definitely not be a problem to double the output of Mithril."

Gretel didn't get the meaning of what he said at all.A spoonful of half-molten ore stretched out in front of him, hot air rushed towards his face, Gretel jumped back reflexively, and took a few steps back:

Don't come here!

My [Cold and Heat Resistant] 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 Charmander?I am not stupid!It is enough to verify that the high temperature can help refine the ore. The next thing can be done by machines, and it is absolutely impossible to do it manually!
Gretel nodded at him carelessly, turned around and walked away.As I walked, I thought: So how to increase the temperature of the furnace? ——Which kind of furnace is the iron-making furnace?blast furnace?Open hearth?Converter?
Forgive Grete for only knowing these names, and he has no idea what one looks like. Even if he puts the picture in front of him and asks him to look at it repeatedly, he may not be able to connect it correctly.

What's inside the furnace like?Where does the fuel come in, where does the ore come in, where does the oxygen blow, where does the molten iron come out, no, where does the mithril semi-finished product come out?Gretel once scribbled with a pen, and the result of the smearing was that there were seven or eight messes on the paper...

And, the hearth seems to use refractory bricks, what are the ingredients and firing methods of the refractory bricks?

I don't know, I don't know, bye.

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

Whether there is oil in this world, Grete doesn't know, anyway, he has never seen it.

Burn hydrogen?
It's too dangerous, and Gretel doesn't want to blow himself up.

Thermite?

Gretel secretly reminded himself, remember to take the electrolytic smelting technology over later, and make some magnesium and aluminum for himself to play with...

Therefore, among all the technical routes, only two words are left for the one that seems most likely to succeed:

Oxygen blowing.

How much do you blow?
do not know.

What is the partial pressure of oxygen?flow?pressure?
do not know.

Where do you blow it from?

do not know either.In Gretel's mind, there was only the word "oxygen blowing" alone.

As for how to blow it...

Gretel took out a bottle of oxygen—saved during the process of electrolyzing water—and pulled out his followers from behind:
"Is it possible to move the gas in this bottle to - or blow to - directly above the fire pool, and come into contact with the magma?"

"no problem!"

Aurora Wharton gears up.He pointed at it casually, and the mouth of the bottle burst.Before the oxygen in the bottle escaped—maybe it escaped, but it was invisible to the naked eye—the translucent force field rolled, and a ball of white light exploded in the magma pool.

"That's it!" shouted the braided dwarf. "That's the fire!"

Then, white light flashed, gone, gone, gone...

Half of the dwarves looked at Gretel, half of the dwarves looked at Aurora, and 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 stance, his chest heaving, and the muscles in his arms bulging.He stared back at Gretel and nodded heavily:

"Come!"

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

"No. The burning time is too short, at least double it. Your Excellency, do you have a solution?"

Yes there is.However, a large amount of oxygen is needed to maintain the air flow... This, the time to test the industrial strength has come!

"There is a way! But it needs the support of the parliament - leave it to me, wait!"

Gretel turned to say goodbye.Go back to the Tongtian Tower and touch the No. 375 laboratory on the 3th floor.The laboratory is a mess, and a new group of people have been working. The sinks, graphite rods, bottles and jars all disappeared.Probably because the electrolytic smelting has been successful, the project team was cancelled, and the magicians went back to their respective homes, looking for their own mothers.

Gretel froze.He stood at the door of the laboratory for three seconds and let out a scream:
"Don't! - people! Come back to me!"

What about the by-products of the electrolysis process!How to use magic for vacuuming is the most efficient!Low-temperature and high-pressure separation of air to produce oxygen, did those magicians come out of their livers!At worst, save two tanks for pure oxygen!
He circled around the door of the laboratory, and circled again, crouching down like a melted candle.Aurora Wharton hurried over to pull him:

"Boss, it's okay. I'll take you to find someone. They are all my brothers and sisters. I know them well!"

"Oro," Gretel looked at him with blank eyes:
"You said, how did they run so fast? They didn't even write papers! Just the separation and measurement of air, you can write several papers, why did they run away???"

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

"Maybe they are waiting for you to write? After all, it is your proposal. They can't write without authorization and rob you of the honor and reward you deserve?"

Gretel: "..."

He belatedly remembered that there was another thing called the 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, most of such researchers are qualified to be the first author, rather than aggrieved second author or third author.

"...Let them write it. After it's finished, it's okay for me to read it. I can just hang up as the corresponding author. ——What I want now is oxygen! Oxygen!"

As long as my patients can inhale oxygen and have enough oxygen to inhale when they have difficulty breathing or during surgery, whose name is on those papers, he doesn't care at all.

On the verge of disbandment, or in other words, the disbanded project team turned efficiently again.

Knowing that Gretel has a way to improve the output efficiency of semi-finished products, magicians immediately followed his request, running up and down as hard as possible.Build a force field box, fill it with air as much as possible, and press it until it can no longer be stuffed in.Then, throw [Frozen Ray], [Frost Breath], [Ice Hockey], [Northern Wind]...

"Very good! Starting to liquefy! Make it all liquid! Then raise the temperature a little bit..."

BOOOOOOM!

At the foot of Igor Peak, the stone flat dedicated to the Horn of Thunder, which is specially used for experiments with explosion hazards, shook twice.The next moment, a strong light shone down from the Tongtian Tower, and Archmage Carlisle followed through the maze and flew down from the peak at high speed:
"What are you doing!"

"Uh... Gretel wants the fire gas, we made it before, and we've used it up..."

Facts have proved that without the presence of a great magician above level 13, relying solely on the force field barrier to liquefy the air, it is really not something that can be played casually...

Regardless, Gretel got what he wanted:
Archmage Carlisle took the lead, leading the three highest-level students to cast spells together, and finally separated pure oxygen with bare hands without the blessing of the mage tower;

Another great magician personally made a thick steel cylinder out of strong steel mixed with fine gold, which is used to make knight weapons;

After filling, it was sent to the Mithril area, where the Alchemy Union of the Alteration School, the great magician responsible for the maintenance of the magic circle, buried pipes in the wall so that the oxygen in the cylinder could be blown directly above the fire pool.

Oh, by the way, the pipe can still be stretched. It stretches out when blowing oxygen, and retracts when it is not blowing oxygen, so as not to spray oxygen from the top of the cave, which is too wasteful...

"Mithril ore smelting, the first oxygen blowing experiment, start!"

Gretel was in the center and calling the shots.Aurora Wharton sat in the corner of the Mithril forging room, hung a [Brute Bull Strength] for herself, and held the rotary valve of the oxygen cylinder with both hands.Standing in another corner, Mage Dumfries pressed the button on the pipe protruding from the ceiling...

The air hissed.Soon, the magma rolled on the edge of the fire pool, and the light of the fire 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 regularly replaces the gas cylinders and takes back the exhausted gas cylinders. This kind of work can be done by anyone. Oh yes, and be careful Don't let the cylinder blow up..."

Gretel walked out humming a song.Not long after, heartfelt cheers erupted from the dwarves in the cave behind.

"Ah, that's right! Where's my oxygen! Leave me a bottle of oxygen!"
