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

Chapter 210 This is what Mithril should do to increase production!
After successfully rescuing Master Tarbert, Gretel suddenly became invincible in the forging area.Not to mention that dwarves nodded and smiled at him walking in and out. Gretel wanted to enter the Mithril area to take a look. The braided dwarf who blocked the way yesterday also stepped aside without hesitation and led him in:
"Go this way! - Walk close to the wall, be careful, you'd better pick up the shield... Forget it, I'll get it for you..."

Gretel reached out and picked up an iron shield. He tried harder, but he still didn't lift it up.He wanted to try again for the third time, but the dwarf with the braided beard had snatched it away. With one arm raised high, he raised the iron shield above his head...

Gretel hid behind the shield the whole time, not daring to take a quick step, nor did he dare to take a slow step.A half-inch-thick rectangular iron shield is on the outside, black and dark, looking like a copper wall and iron wall.Well, I have to say, it still feels very safe.

what?
Shield?Mage armor?

That kind of fully transparent thing, after it is released, it will be invisible in a flash, and it doesn't feel like it at all, okay!
Gretel followed the braided dwarf and saw the original appearance of the Mithril mine, the crushed and washed ore powder, and the crumpled and pitted intermediate product after being rolled in the fire pool.As the braided dwarf walked, pointing at the products of each stage, he babbled to Gretel:

"Actually, digging mithril mines is very troublesome, but as long as you find a good mine, you can still produce a lot of ore. It's okay to make ore powder, but it's just everyone working hard and wielding a hammer. If you want to burn it piece by piece like this It's not easy, without a good enough fire pool, it can't be burned at all. We only have this fire pool here, and there seem to be only three fire pools in the whole kingdom..."

Understand that the difficulty of smelting semi-finished products lies in the combustion temperature.In the future, you can recommend things like coke, blast furnace, oxygen blowing, etc. to them.Grete nodded in understanding, and continued to listen:

"This is the best pool of fire, I can't walk through it. Only old Theon can stand by the side of the pool here. He is the only one with the most poisonous eyes, who knows when to fish..."

Hmm, so most people can't get past it and need a robotic arm?If you still want to master the flame temperature, consider a metal thermometer?
"But it's actually not too difficult to fish things. With good luck, old Theon can fish several pounds a day. But in the end it's made into Mithril...just..."

His eye circles suddenly turned red.The stocky man with about the same height and diameter squatted down, and instantly changed from a square cube to a flat pier:
"Except for high-level divine arts, nothing can do... Only the master is carrying it... You magicians have been urging, always urging, the master must be strong, obviously tired like that, and still refuse to stop for a day... ..."

"That's why the council sent me here." Gretel followed him and squatted down, and the height difference between the two narrowed down a lot.He bent down slightly so that he could look directly into the other person's eyes:
"The council sent me here to find other ways to increase production so that the master would not be so tired. Don't worry, I won't urge the master... By the way, when I use magic to make mithril later, can you let me Shall I watch?"

"Just watch!"

The braided dwarf took Gretel around a long way, found a place in the deepest part of the Mithril area, and settled him down.Gretel squatted on the ground, with his back against the cave wall, poking out one eye from behind the iron shield, and continued to watch the smelting of divine arts:

Alas, the braided dwarf has already knelt on the ground to pray, and I have to support this shield by myself, it's so heavy...

Gretel knelt on his knees, crossed his forearms to form a triangle, and supported the shield with all his might.Not far from the front left, the magic on the high platform has already started. A round translucent cover is suspended in the air. At the bottom of the cover, the gray half-finished Mithril sinks quietly there, looking harmless to humans and animals.

The dwarves continued to pray.Once, twice, three times, the voice became louder and louder, and finally, a blazing white light suddenly lit up inside the circular translucent cover!

Gretel: ! ! !

With sharp eyes and quick hands, he used his left shoulder to support the iron shield, and with his right hand, he took out the piece of glass that had been painted with ink ten times, and held it up to his eyes.With the protection of the glass sheet, the white light is much gentler. Gretel muttered while observing:
"...Why does it look so much like an arc..."

Regardless of whether it is an arc or not, in short, there may be a direction.Although Gretel was a clinical medicine major in his previous life, he had also heard of the use of electrolysis to smelt metals—at least, he still knew about electrolytic aluminum.As for whether this white light is electricity...

Gretel took back the glass piece, fumbled in the interspatial bag, and took out a long wooden stick with a magnet attached to it.Holding his breath, he stretched the wooden stick out of the iron shield, trying to level it as much as possible.Half a minute, 1 minute, the outstretched right hand began to tremble, and the silk thread tied to the magnet also rippled slightly.

Gretel: "..." How come the more you live, the more you go back. In the previous life, you won't shake your hands even if you pull a hook!Forget it, it's probably due to supporting the iron shield with his shoulders. The shield is too heavy, which affects the power of his right hand...

Gretel thought for a moment, gave up the wooden stick, and grabbed the end of the silk thread that tied the magnet with the magician's hand.This is really useful, the magnet swayed twice and then it quieted down, hanging in the air without moving.

Gretel waited patiently for a while, the prayer sounded again, and the white light shone into the void again.And the magnet that Gretel was hanging in mid-air also started to rotate slightly.

The magnet turns!

There was no one running over with a magnet, and the big iron shield and other iron objects did not move... The magnet turned inexplicably, considering the strong magnetic field, considering the electromagnetic reaction, considering...

Consider, the white light in that magical mask is a strong current!

In the darkness, Gretel's eyes became brighter and brighter.

Early the next morning, Gretel returned to the mage towers at the top of the peak with a thick stack of papers on the electrolytic mithril experiment, and found Archmage Carlisle again.

"Master, I have a few ideas about the method of mithril smelting..."

Holding the pre-clamped bookmarks, he divided the thesis into several parts.Each section has text, diagrams, instructions, and large, blank forms to be filled out.Master Carlisle opened them one by one, and the more he looked, the more he frowned:

"Method [-]: Make mithril powder into thin rods, insert pure salt with graphite thin rods, heat until the salt melts, and turn on electricity... The formula of the thin rods needs to be tried, the heating temperature needs to be tried, and the current needs to be tried... It may take To be carried out in a vacuum, possibly in...a gas...see the appendix for the method of gas production..."

"Method [-]: Fill the graphite crucible with quicklime, bury the steel mesh in the quicklime, and fill the mesh with Mithril ore powder... Increase the temperature, and conduct electricity in the molten salt of quicklime...Temperature and current need to be tried..."

"Method [-]: Compress graphite powder and mithril powder, insert molten salt, and conduct electrolysis at a certain temperature..."

Master Carlisle saw his temples throbbing wildly.Finally, he pushed the paper in front of Gretel and crossed his fingers:
"What about your temperature? What about the current? How do you make the thin rod formula? Do you conduct electricity in a vacuum, or in... what gas? Do you know the detailed method?"

"do not know!"

Gretel held his head high, confidently:

"It's because I don't know, that's why I want to try! Now I have an idea, a direction, no one, and no strength to do experiments. This is not——

Come to the parliament to apply for the project! "
