Reborn as the Lord of Another World

Chapter 23

"Come on, try putting these two iron plates together," Roland said.Anna stretched out her fingers and pressed them on the seams of the iron plate. Flames spurted out from between the fingers, and the joints melted at a speed visible to the naked eye.

"Reduce the firepower and try again from the back."She nodded and did it again. The two iron plates are spliced at 90 degrees and are firmly welded together.

Roland carefully inspected the joint and found that the effect was just as he imagined - a perfect weld without any flaws. If a littleAfter polishing, the traces of fluid during the melting of iron are removed, and the two iron plates are almost the same as the forged bodies formed in one go.

"Very good, Miss Anna, it's simply great," Roland couldn't help but admire, "Next, let's connect the other two iron plates.""What is this? An iron... bucket?"

"No, it's a cylinder," he corrected."Cylinder?" Anna repeated in confusion.

"Yes, it can be used to fill the air," Roland pointed to another square iron plate, "See the small hole on it? The air comes from thisThe small hole enters the cylinder and pushes the piston. Well, the piston is an iron plate with a slightly smaller inner diameter than the cylinder. It can move freely inside the

cylinder. "Even Anna was confused in front of so many coined words, "What are these...cylinders, pistons, etc., for?"

"To make a machine that can move automatically."

The steam engine brought the motive force required for mankind's first industrial revolution and completely liberated manpower and animal power.

Its schematic diagram is familiar to every robot dog. To put it simply, it is an enlarged version of a water kettle. Boiling steam is introducedThe cylinder drives the piston and connecting rod, converting thermal energy into mechanical energy.

The principle is extremely simple, but that doesn't mean it's easy to manufacture. The difficulty lies in the sealing of the cylinder and piston, as well as the manufacturing of the gas pipeline. MetalWhen you don't have enough processing skills, it is simply impossible to forge a qualified cylinder by hand.

However, Anna’s ability perfectly made up for her shortcomings in craftsmanship.Roland only needs to design four iron plates of the same size in advance, have them cast and polished by the blacksmith shop, then use straight plates to fix the shape, and then Anna will weld

them to get a square cylinder with extremely high rigidity. With the help of the witch, he did not have to build a cannon barrel boring machine and then process a round cylinder like the traditionalproduction process. The same goes for other large parts. They can be made into small pieces first and then spliced together. In this way, even a small workshop like a blacksmith shop can jointly

manufacture all the parts needed for a steam engine.In fact, before welding was invented, people could only rely on bolts or riveting to connect small parts, and the inside of the cylinder must require smooth, regular connections.

Obviously this can't be done.The only problem is the tube. There is nothing special about its production method. A long piece of iron plate is heated until red hot, then placed into a grooved mold, and hammered into shape

with a hammer. This is also the barrel of a front-mounted flintlock gun. The production method. It's just that the barrel still needs to be straightened, rifled, etc., which is more complicated.The trouble is that Roland can't call the blacksmith to his back garden, the witch can't be exposed for the time being, and blacksmithing is really not his own.

strengths. In desperation, he had no choice but to let the chief cavalry do it for him while he commanded from the side.After three days of struggling like this, Roland finally built the first steam engine in the backyard.

"Is this your infinitely powerful thing?" Carter frowned and looked at this strange machine. He was first sure that this thing had nothing to do with cult rituals. Every iron knot on it was installedby himself, making it look like a sealed stove. It would be unreasonable if demons could be attracted to it.

But how do you move a bunch of iron lumps? It looks very clumsy and has no legs. Is it possible that it can still survive?

But in Roland's eyes, this seemingly simple machine exudes industrial beauty. Standing on the shoulders of giants, he naturally did not follow the route of Newcom steam

engine, Walter steam engine, or improved steam engine. His first prototype was a high-pressure steam engine with a double connecting rod and a sliding valve. Its production isnot much more difficult than the most primitive steam engine. The key lies in some innovations in thinking.

"You'll find out later."Roland poured a bucket of water into the steam room and asked Anna to light the firewood.

Ten minutes later, the water was boiling and rolling. Soon, there was a crackling sound in the cylinder, and Roland knew that it was the cylinder being heated.Expansive sound. The iron plate of the piston is thinner, and the expansion deformation is greater than that of the cylinder body, and it will eventually press firmly against the cylinder wall.

"Isn't this boiling water? I didn't expect it to be a stove," Carter muttered.When the cylinder was filled with steam, a scene that made Roland extremely excited appeared. The piston starts to push the connecting rod outward. When it reaches the

top, the other connecting rod pulls the sliding valve door, and the steam pushes the piston inward. The two connecting rods drove the wheels to rotate rapidly back and forth. Asthe fire power increased, the speed quickly reached its peak.

The machine made a piercing roar, and the exhaust wheezed out white gas, which seemed to be unstoppable."Is this what you said...the power hidden in nature?" Anna asked blankly.

The chief rider's face was filled with disbelief. He had spent a lot of effort to install the last big iron wheel, but now it was spinning as fast as a frog. Standing next to him, hecould even feel the vibration of the wheel. The air flow blowing against my face - this can only show that the power of the iron lump in front of me has reached an astonishing level.

A sense of uneasiness gradually rose in his heart.His Highness said that it can replace human and animal power. If you are not deceiving yourself, when it replaces horses to pull war wagons, just with this brute force, it will

I'm afraid even ten riders will be unable to resist.It takes fifteen years to train a qualified rider, but only three days to build such an iron furnace. Counting the time spent by the blacksmith crafting the parts

time, only a week.

It does not need to be fed, is not afraid of cold and hunger, and is not afraid of arrows or guns. As long as the front is equipped with a ram, it can run rampant on the

battlefield.In this case... is it still necessary for traditional riders to exist?

*********************At night, when Roland returned to the bedroom, he saw the nightingale for the first time.

She did not wear a hood this time, and sat at the table with a smile on her face, fiddling with several pieces of paper in her hands, "It seems that the rumors from theoutside cannot be believed. They say that the fourth prince has no academic skills and a bad character. It’s terrible, in fact it’s not much better than the palace master. What’s

drawn on this paper is the design of that iron stove? You call it... a steam engine, right?”When I go, can I still leave some privacy for others? I can come and leave whenever I want. Do you think this is your home? Roland cursed in his heart.

He still replied nonchalantly, "It's a design, yes, but without Anna's help, it's just a drawing.""What can it do?"

"There are many, including ore transportation, drainage, iron smelting, and forging. It can be used wherever strong gas is needed.""Then I'll accept it." Nightingale rolled up the paper and put it into her robe. "There are also people in the Mutual Aid Association who can control fire."

"Helloÿ"She waved her hands to stop Roland's protest, "Of course, I'm not taking your things for nothing, you should take a look at this first." She took a small ball of white stuff and

Put something on the table.Roland walked over, picked it up with his fingers, and found that it was actually a roll of paper.

He unfolded it gently and glanced twice, "This is..."

"A secret message delivered by a carrier pigeon," the Nightingale said in a joking tone. "The recipient is your maid, Tire. Tsk, it seems that your queen

The palace is not stable. ""I haven't touched her," Roland frowned.

Tyr, in his memory, this girl seems to have followed him for a long time. The fourth prince was originally very interested in her, but he harassed her several times but failed. This timewhen he came to Border Town, he promoted her to the rank of head maid and served him personally. Her room was arranged next door. Unexpectedly, it was actually the spy arranged by

Brother Wang and Sister Wang?Although the letter was unsigned, judging from the content, it was probably written by those brothers and sisters. The letter said that it failed last time

The master is very dissatisfied. Next time he takes advantage of the commotion in Longsong Fortress, he will never allow another failure. Well, actually you have succeeded,he thought, otherwise he would not become Roland Wimbledon.

It is unlikely that this letter was forged by Nightingale, because only those involved in the conspiracy would have known clearly about the first assassination plan.But if Nightingale wants to kill herself, there is no need to bother.

"Did you steal it from her?""Your maid is not that stupid. She planned to burn it after watching it. It's a pity that I happened to be behind her when she watched it," she said.

An action of changing the contract, "So, what are you going to do? Do you need my help to "handle" it? "Roland naturally understood what she meant. After hesitating for a moment, he finally nodded and said, "Sorry to bother you." This kind of thing

He really didn't have the confidence to do it himself, "If you can...ask for me who is the person behind her.""As you wish, Your Highness," Nightingale smiled and bowed, "Then this roll of drawings is the reward."
