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

Chapter 366 Magic Hand Rubbing the Sealing Ring

Gretel worked hard for half an afternoon in the treatment and used up 20% of his mental power before announcing that the day's treatment was over.

Thank goodness, thank you, for the rules the world knows.The caster's daily spells are limited, and the caster has to sleep every day to recover the spells.No one will force a healer to work overtime, and forcing doesn't work...

So by dinner time, Gretel closed the stall, saying that the treatment was over, and no one complained.And he himself hastily picked up two bites of food, and holding today's harvest, he knocked on Archmage Serrano's door.

"Come in!"

As soon as Gretel pushed the door open, he immediately backed out and put a bubble spell on himself. — The room was smoky, half gray and half white, and the Tyndall effect of the chandelier was very obvious.Just now, how many people had a meeting here, and how many cigarettes they smoked!
Simply unbearable!

If you can't bear it, you have to bear it.Gretel walked in with the bubble technique, and the room was indeed full of people, filled with smoke, and everyone's face was illuminated by the lamp like a ghost.Archmage Serrano glanced at Gretel and pointed casually:
"Sit down.—what's the matter?"

"Uh, I'll come back later?" Gretel looked left and right.This posture obviously means that the discussion about something is not going well, and it suffocates a group of old men, smoking desperately.It seems inappropriate to talk about his little things now?

"It's all here, sit and listen." Archmage Serrano ordered casually.He had a good impression of Gretel in the previous days of communication, and he didn't mind letting this little fourth-level mage join the meeting. A soft wind swept out and pushed Gretel to sit on the side.

As soon as he sat down, a bald magician next to him patted the table: "Those stinky stones! They are so stubborn, they won't give up at all! Isn't it just ore? I gave them all the explosives, so I don't need to dig them one by one. Just drag it out, that's all, and sell it at a high price!"

"Drink them to death!" Another magician also complained. "For each exchange of materials, it is obviously enough to buy food, but I have to buy wine! I also need to buy spirits! If one person drinks less, he can also save ten catties of mines!"

"Can't the mine road be changed? Or, use something to make it easier for them to pull? Magic puppet?"

"Just kidding! That's too expensive! It's better to increase the purchase price!"

The magicians chattered.Archmage Serrano suddenly remembered something, turned his head and asked:

"Harry, that last time you said—"

He made a back and forth push and pull gesture.The magician named Harry shook his head:
"That doesn't work. It's okay for playing and playing. I really let it work. The air leaks too much and can't be sealed. I have tried gum, gum, twine, and raw lacquer. They either don't work or are too bad. quick."

Gretel kept listening.Hearing this, my heart suddenly moved:
"Your Excellency, what are you talking about?"

"You don't know?" Harry turned to look at him with a strange expression on his face:

"I remember that your mage tower also used this, and Novad also published a paper—"

As he spoke, he raised his hand, and the phantom jumped up immediately, occupying the entire coffee table.Gretel understood at a glance:

He knows this thing!Steam engine!

To be precise, it is a reciprocating steam engine.In the mage's tower, he also built one to generate electricity.It is indeed a good way to use it as a power to pull the mine cart up from the mine.If it can be popularized, dwarves can save more than half of their labor, and they don't have to complain about working too much, but their income will not increase...

But steam engines are not very efficient.As this Master Hari said, most of the steam escaped.The ability of twine and raw lacquer to bond is really a headache. It is almost leaking while working, and it needs to be repaired and blocked every three days.If you want to make a good seal, you can only let the magician of the transformation system go into battle in person, and use the shaping ability to directly rub it with your hands.

With this method, it is no problem for a magician to make one for fun, but if he wants to put it into industrial production, the cost is simply a joke.

Fortunately, this afternoon, he made an unexpected discovery——

"Look at this!" Gretel held out the things he just bought in the afternoon.A bunch of gray balls, big and small, ranging from the size of a fist to the size of a thumb, slightly elastic.All of a sudden, the eyes of the mages gathered:
"Oh, gumball. What's up?"

This thing is useless.When it is just cut from the tree and it is not dry, it can also be applied on cloth or the outside of leather shoes to make raincoats and rain boots.After it's done, it's useless except to cut it into small balls like this to amuse the children...

"Your Excellency, would you try using sulfur with it?"

"How to try? Heat it?"

"Uh...probably...?"

Poor Gretel knew nothing but the word "sulfurization reaction."He was completely at a loss as to the ratio of rubber to sulfur, whether it needs to be heated, to what degree, whether to use a catalyst, whether to put it in a solvent...

He didn't study chemical engineering!

Fortunately, besides Archmage Serrano, there were two mages from the School of Change among the people present.The three people each took a rubber ball, added sulfur, and tossed it in different ways.

There are dots of stars in the void, constantly tumbling.Gray rubber, light yellow sulfur, kneaded into a ball by invisible hands, and flames, electric lights, and various energies shuttled back and forth.Some emit black smoke, some emit flames, and some disperse into fine sand.Gretel looked left and right, sighing secretly:
The mage is worthy of being the primary productive force. He really doesn't have the ability to rub his hands for chemical reactions...

Three magicians, more than a dozen plans, started at the same time.If one doesn’t work, change to another, if it doesn’t work, change to another.The left and right sulfur are common materials, and the rubber balls were contributed by Gretel, so they can be wasted.

Soon, Master Harry exclaimed in surprise:
"It's changed! It's softened!"

He summoned the Mage Hand and rubbed it around in the force field, kneading the softened rubber.Squinting his eyes for a while, he suddenly slapped the space bag and poured out a steam engine that was half the height of a person and the length of a person.

The rubber in his hand changed shape arbitrarily, suddenly flew up, and became a solid layer of paste on the steam engine.

Before Gretel could react, there was a sound of gurgling water, followed by rising flames.The steam engine is booming, steam is rolling, and work is started!
The mages were silent and silent again.Anyone can see that this kind of sulfur-added rubber ball has good elasticity, compactness, and heat resistance, and is very suitable for being used as a sealing material on a steam engine.The only question now is how long it will last.

and also……

"How much of this material is there?"

Gretel picked up a corner of the space bag and dropped it down.Large and small balls rolled out one after another, and quickly piled up on the coffee table in a pile of half a square meter.He spread his hands:

"That's all. I bought them all in that store."

So, it was a coincidence that such a useless thing was brought to the Dwarf King City...

In any case, with suitable materials, there is a solution.After two days and two nights of continuous testing, the magicians have been able to determine:

Rubber is used as a sealing material, which is more than a step higher than the previous raw lacquer + twine.

That's it.Natural rubber can be imported on a large scale.Take advantage of the fact that no one else knows the purpose, and quickly scan the goods!shopping!
So, when the negotiations resumed, Archmage Serrano slapped the table and refused to budge:

"It is impossible to reduce the price of ore! - Big deal, we will provide a batch of power to help you pull out the ore!
By the way, we ordered a batch of such machines..."

Steam engines can be imported in large quantities!Just in time to place an order!The craftsmanship of the dwarves is still trustworthy!
perfect!

Happy Mooncake Festival!
I don't know what I was thinking at noon, but I actually wrote it as Zongzi Festival...

Ask for subscription, ask for monthly pass, ask for recommendation ticket, ask for book review, ask for various...

　Little Gretel led the magicians to a fork in the road.

　　In fact, rubber can't withstand the high temperature and high pressure of the steam engine. Later, it depends on the processing accuracy. The sealing gasket is made of copper... Copper is relatively soft and easy to deform, and it can be glued when screwed on... (I asked my family to work in a power plant The old man, did he use rubber as a gasket and was sprayed by him)

　　But of course, compared with Watt's use of silk as a seal at that time, the rubber is still fragrant^^
　　ps: Thank you Song of Thorns for giving me chapter push...

　　In the past two days, I re-watched "Ding Wei's Chronicle" and started to watch "The Chronicle of Qing Gui". I couldn't stop watching it, it was so delicious
