Chapter 366 Magic Hand-Rubbed Sealing Ring

Gretel worked hard for half an afternoon, using up 20% of his mental energy, before announcing that the day's treatment was complete.

Thank God, thank earth, thank the world for its well-known rules. The caster's daily spells are limited, and the caster has to sleep every day to recover his spells. No one will force healers to work overtime, and forcing is useless...

So at dinner time, Grete closed the stall and claimed that the treatment was over, so no one complained. And he hurriedly took two bites of rice, then took today's harvest and knocked on Archmage Serrano's door.

"Come in!"

As soon as Grete pushed the door open, he immediately stepped back and cast a bubble spell on himself. ——The room was filled with smoke, half gray and half white, and the Tyndall effect of the chandelier was very obvious. How many people were having a meeting here just now, and how many cigarettes were smoked!

It’s simply unbearable!

You have to endure it even if it is unbearable. Grete walked in using the bubble technique. As expected, the room was full of people, filled with smoke, and everyone's face was illuminated like a ghost by the lamp. Archmage Serrano glanced at Gretel and pointed casually:

"Sit down.—What's the matter?"

"Uh, I'll come back later?" Grete looked left and right. This posture obviously meant that the conversation was not going well, which made a group of old men choke up and started smoking. Doesn't it seem appropriate to talk about his little things now?

"You're all here, sit down and listen." Archmage Serrano ordered casually. In the past few days of communication, he had a good impression of Gretel, and he didn't mind letting this little fourth-level mage join the meeting. With a wave of his hand, a soft wind blew out, pushing Gretel to sit on the edge.

As soon as he sat down, a bald magician next to him slapped the table: "Those stinky rocks! They are so stubborn and won't give in at all! Isn't it just ore? The explosives are all given to them, so there is no need to dig them out with pickaxes. Just drag it out, that’s it, and sell it at a high price!”

"Drink them to death!" Another magician also complained. "Every time we exchange materials, we can obviously buy food, but we have to buy wine! We also need to buy spirits! If one person drinks less, he can save ten kilograms of mine!"

"Can't the mine tunnel be modified? Or use something to make it easier for them to pull it? A magic puppet?"

"You're kidding! That's too expensive! You might as well increase the purchase price!"

The magicians were all talking. Archmage Serrano suddenly remembered something and turned his head to ask:

"Harry, what you said last time -"

He made a push-and-pull gesture. The magician named Harry shook his head:

"That won't work. I tried it for fun, but when I really made it work, the air leaked too much and couldn't be sealed. I tried gum, gum, twine, and raw lacquer, but they either didn't work or were too damaged. quick."

Grete kept listening with his ears pricked up. When I heard this, my heart suddenly moved:

"Sir, what are you talking about?"

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

"I remember you also used this in your mage tower, and Norward also published a paper——"

As he raised his hand, the phantom immediately rose up and occupied the entire coffee table. Gretel understood immediately:

He knows this thing! Steam engine!

To be precise, it is a reciprocating steam engine. He also built one in the mage tower to generate electricity. It is indeed a good way to use it as power to pull the mine cart up from the mine. If it can really be popularized, the dwarves can save most of their labor, and they don't have to complain about too much work, but their income has not increased...

But steam engines are not very efficient. As this Master Harry said, most of the steam was lost. The bonding ability of twine and raw paint is really a headache. It almost leaks while working, and needs to be repaired and sealed every three days. If you want to seal it well, you can only let the transformation mage personally go into battle 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!" Grete held out what he just bought in the afternoon. A bunch of small 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 over:

"Oh, rubber ball. What's wrong?"

This thing is useless. Just cut from the tree, before it dries, you can also apply it on cloth or the outside of leather shoes to make raincoats and boots. After it's dried, it's good for nothing except cutting it into small balls like this to amuse children...

"Sir, would you like to put sulfur together with it?"

"How to try? Heat it?"

"Uh...probably...?"

Poor Grete didn't know anything except the words "vulcanization reaction". He was completely at a loss as to what the ratio of rubber to sulfur was, whether heating was needed, to what degree, whether a catalyst was needed, and whether it should be placed in a solvent...

He didn’t study chemical engineering!

Fortunately, everyone present, in addition to Archmage Serrano, also had two mages from the School of Change. The three people each took a rubber ball, added sulfur, and played with it in different ways.

The stars in the void are dotted and rolling. Gray rubber and light yellow sulfur were kneaded into a ball by invisible hands, and flames, lightning, and various energies shuttled back and forth. Some emitted black smoke, some emitted flames, and some scattered into fine sand. Grete looked left and right, sighing secretly:

The mage deserves to be the most productive person. He really doesn’t have the ability to create chemical reactions by hand...

Three magicians, more than a dozen plans, started at the same time. If one type doesn't work, change to another; if it doesn't work, change to another. The left and right sulfur is a stock material, and the rubber ball was contributed by Gretel, but it can't be wasted.

Soon, Master Harry shouted in surprise:

"Changed, changed! Softened!"

He summoned the mage's hand and rubbed it back and forth in the force field, kneading the soft rubber. After squinting his eyes for a while, he suddenly tapped the space bag and poured out a steam engine that was half a person tall and a person long.

The rubber in his hand changed shape arbitrarily, suddenly flew up, and smeared firmly on the steam engine.

Before Gretel could react, there was a gurgling sound, followed by flames rising. The steam engine roars, the water vapor rolls, and work begins!

The mages were silent again and again. Everyone can see that this kind of sulfur-added rubber ball has good elasticity, density, and heat resistance, and is very suitable for use as sealing material on steam engines. The only question now is how long it can last.

besides……

"How much of this material is there?"

Grete picked up a corner of the space bag and poured it down. Balls, large and small, rolled out one after another, and soon there was a pile of half a square meter on the coffee table. He spread his hands:

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

Just, it was a coincidence that such a useless thing could be brought to the Dwarf King's City...

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

As a sealing material, rubber is much better than the previous raw paint + twine.

That'll do. Natural rubber and the like can be imported on a large scale. Take advantage of the fact that no one else knows the use, so hurry up and grab the goods! shopping!

So, when the negotiations resumed, Archmage Serrano slammed the table and refused to give in:

"It's impossible to lower the price of ore! - At worst, we will provide a batch of power to help you drag out the ore!

By the way, let’s order a batch of machines like this..."

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

Perfect!

Happy Mooncake Festival!

I don’t know what I was thinking at noon, but I actually wrote it as Zongzi Festival...

Please subscribe, ask for monthly tickets, ask for recommendation votes, ask for book reviews, ask for all kinds of...

Little Gretel took the magicians on a side road.

In fact, rubber cannot withstand the high temperature and pressure of steam engines. Later, it relied on processing accuracy. The sealing gasket was made of copper... Copper is relatively soft and easy to deform. It can be glued when screwed on... (I asked my family who works in a power plant. The old man, did he use rubber as a gasket? He gave him a good slap)

But of course, compared to the silk seals used by Watt at that time, rubber still tastes good^^

ps: Thanks to Song of Thorns for giving me a lot of chapter recommendations...

In the past two days, I re-read "The Chronicles of Ding Wei" and started watching "The Chronicles of Qinggui". I couldn't stop watching it. It smells so good.
