The New Civilization of Witches

Chapter 23: A new source of power

"Come, try to combine these two iron plates together" Roland said.

Anna's finger pressed the iron stitch. A flame was released from his finger, melting the interface with a speed visible to the eye.

"Reduce firepower and start again with the reverse side."

Anna nodded and did it once more. Both iron plates are welded firmly at a 90 degree angle.

Roland carefully examined the interface and found that the effect was exactly what he had imagined

- perfect welding without defects.

With a little polishing, traces of iron liquid can be lost.

There is no difference with modern welding techniques.

"That's great, Miss Anna, it's amazing!"

Roland excitedly exclaimed, "Furthermore, we should also weld these two iron panels together."

"Whatis that?

"Iron... bucket?"

"No, it's a cylinder" Roland corrected.

"Cylinders?" repeat Anna, confused.

"Yes, the cylinder can be filled with air"

Roland pointed to another square piece of iron,

"Did you see a small hole on it?

Air can get into the cylinder through that small hole, and push the piston.

Nah,

and because the piston diameter is slightly smaller than the cylinder diameter.

Even the genius Anna, in front of so many unknown words, had a question mark over her head,

"this.cylinder, piston, and so on, what do they do?"

"They are needed for the purpose of making machines that can move automatically."

The steam engine brought the first industrial revolution, it was the driving force behind human development, completely replacing humans and animals in the workforce.

It was a schematic diagram that every mechanical engineer was familiar with, to describe it in simple words,

it was a larger version of the kettle. Once the water boils, the resulting steam will be induced into the cylinder.

There, it will push the piston connected to the mast. Like this, heat energy is converted into mechanical energy.

The principle is very simple, but that does not mean it is easy to make.

The difficulty lies in the sealing of cylinders and pistons, as well as the production of gas pipes.

Without proper metal processing skills and relying solely on manual forging, making usable cylinders would only be a dream.

However, with the help of Anna's abilities, she could make up for their lack of manufacturing skills.

After much planning earlier, Roland came up with a design using four iron plates of the same size, like this,

so that the blacksmith can easily grind it.

Then the iron plates will be welded together at a 90 degree angle with

Anna's. Like this, it is possible to get a very rigid square cylinder.

With Anna's help, she didn't need to use the traditional production process. They first created a tube-shaped drilling machine,

and then process it to make a circular cylinder. Other large parts can also be divided into small parts and then welded together. In this way,

it is even possible to produce it in a small workshop. In this way, they were able to produce all the components needed for the steam engine.

In fact, before the invention of welding, one could only rely on the splicing of small pieces by way of bolted or riveted.

Since the internal cylinder had to be seamless, the normal connection method was clearly unable to do this.

The only problem is the gas pipe.

The production process is not special, it needs to be heated to red, and then the groove can be hammered into the right shape;

it is also a method of producing a front-loading flintlock gun barrel.

Later the barrel only need straightening and counterbored rifling etc, nothing too complicated.

The problem was that it was impossible for Roland to summon the blacksmith to the garden behind the castle, as it was still unknown that Anna had not been executed.

Blacksmithing was not one of their strength, but in a desperate attempt, they had to let the head knight do it, under Roland's own control.

Reigning.

After waiting for three days, Roland finally had the first steam engine standing in his backyard.

"This is the powerful machine you're talking about?"

Carter frowned while looking at the strange machine, but he had confirmed directly that this machine had nothing to do with magic.

Each of the iron plates was personally shaped by itself, and to him, it only looked like a closed furnace.

It was impossible for the devil to be attracted to him.

But how could it move a pile of chunks of iron upwards?

It looked extremely clumsy and had no legs, was it possible that he could fly?

But in Roland's eyes, this simple-looking machine exuded the beauty of modern industry.

Standing on the shoulders of giants, he naturally did not need to find

A newcomer steam engine - or Watt steam engine, instead he built a better steam engine.

Its first prototype was already a high-pressure steam engine with double connecting rods and sliding valves.

To make it better than most original steam engines, the key lies in some of the newer innovative ideas.

"You'll understand soon."

Roland poured a bucket of water into the steam room and told Anna to light the firewood.

Ten minutes later, the water was boiling. Immediately, a creaking sound could be heard from the cylinder.

"Isn't this a water kettle?

I don't think it's really a furnace, Carter murmured.

When the cylinder was filled with steam, a scene burst forth. The piston rod starts pushing outward, the,

and when your movement reaches its peak, another rod will pull the sliding valve, allowing the steam to push the piston inward again.

The wheels connected to the two poles will rotate very quickly through this movement, and with the increase in power, the speed reaches its peak very quickly.

The machine let out an ear-piercing humming sound, and white gas was ejected, producing a sort of unstoppable and imposing aura.

"That's what you call ... hidden forces in nature?" asked Anna, stunned.

The face of the knight's head was filled with astonishment, the huge iron wheel he needed to put up a lot of strength, he said,

now it's spinning like a feather. Standing beside the steering wheel he could even feel the fresh breeze - this only showed the tremendous power of the steam engine.

In his heart, a trace of anxiety gradually appeared.

His Majesty said that it could replace the power of humans and animals, he said,

and it doesn't seem like he's lying. When placed on a horse-drawn carriage, it would be very difficult for the 10 knights to resist its brute force.

Training a qualified knight took fifteen years, but the manufacture of such a machine only took three days.

If the blacksmith only worked part-time, it would still only take a week.

It does not require eating and is not afraid of cold or hunger.

It was also not afraid of arrows and swords. Just install a ram in front of him, and it could rampage on the battlefield.

As a traditional knight.is his existence still necessary?

In the evening, when Roland returned to the room, Nightingale once again waited for him.

This time, she did not wear her veil, and she smiled and sat down at the table. His hand played some parchment, though,

"It looks like the rumors outside are really unbelievable. They say the 4th Prince is stupid and has a bad character,

in reality, he should have no learning or skills. In fact,

compared to the great masters of the palace he would not have time for politeness. The picture on this paper, is this the plan for a steam stove?

You call it ... steam engines, right?"

Shoot it! Can't I get a little privacy?

Come and go as you wish, Do you think this is your home?!

In his heart, Roland cursed at him nonstop, but he still replied with a calm face,

"Yes, that was the plan, but without Anna's help, it would just be a picture forever."

"What can he do?"

"Many, these can help with ore transport, drainage, metal fabrication, forging, everywhere where strength is needed can play a role."

"Then I will take it," with these words

Nightingale picked up the parchment and placed it on her robe,

"Cooperation Witch Association has witches with fire power as well.

"Hi-i"

He shook his head to stop Roland's protest, "Of course, I didn't just take your things, look at this first before complaining."

He placed a small amount of white stuff on the table. When Roland went to the table, he discovered that it was actually a scroll of paper.

He gently expanded the scroll, and swept through the contents, "This is .."

"The secret letter sent by the pigeons,"

Nightingale explained to him in a pleased tone,

"the recipient is your maid Tyre, tsk, it looks like your harem is unfaithful."

"I haven't touched it yet" Roland frowned.

Tyre, he could remember that he seemed to be following her from a very early age, and the former 4th Prince seemed to be interested in her, she said,

but unfortunately he failed to successfully conquer it, he could only slightly harass it a few times.

Here, in Border Town, to prevent his personal servant's long wait, he obtained the room next to him.

He did not expect that this was actually an arrangement made by one of his siblings.

Although this letter was not signed, but according to its contents, he could judge, the letter was sent by one of his brothers.

In the letter it is revealed that the author is very unhappy with the last failure, the,

but the riot plans in Longsong Stronghold were not allowed to fail again.

Actually, the first plan must have worked, he thought, or he would never be Roland Wimbledon.

It is impossible for this letter to be faked by

Nightingale, because only the people involved in this conspiracy could know the first murder plot.

And if Nightingale wanted to kill him, it wouldn't be a problem for her.

"How could you steal this from him?"

"Your servant, Tyre, is not stupid, his intention was to burn the letter after reading it.

Unfortunately, he looked away when I was right behind him" He did a sweeping action, something,

"So, how do you want to handle this?

" Do you need my help to 'facing it? "

Roland naturally understood what he meant by 'deal', so he hesitated for a moment, then he finally nodded, nodding,

"I have to trouble you" He doesn't have the confidence to do this kind of thing on his own,

"if you can.. Ask him who the man in the dark is."

"As far as you are concerned, Your Majesty," Nightingale smiled as she saluted,

"Well, this is gonna be a gift for drawing a steam engine."
