Release that Witch

23. Chapter 23 Sources of Power

    “Come on, try putting the two iron plates together,” Roland said.

    Anna held out her finger and pressed it on the seam of the iron plate. The flame is ejected from the fingers and the interface melts at a rate visible to the naked eye.

    “Reducing the firepower, come back again.”

    She nodded and did it. The two iron plates are spliced ​​at 90 degrees and are firmly welded together.

    Roland scrutinized the lower interface and found the effect as he imagined—a perfect weld without any flaws. If it is slightly polished, the fluid traces from the molten iron are removed, and the two iron plates are almost the same as the once-formed forged body.

    “Very good, Miss Anna, it’s great,” Roland couldn’t help but admire. “Next, we’re connecting the other two iron plates.”

    “What is this?” Made of iron…bucket

    “No, this is a cylinder,” he corrected.

    air cylinderAnna Confusedly repeats.

    “Yes, it can be used to fill the air,” Roland pointed to another square iron plate. “Do you see the small hole above? Air enters the cylinder from this small hole and pushes the piston—呃, which is an iron plate that is slightly smaller than the inner diameter of the cylinder and can move freely in the cylinder. ”

    Even Anna, in front of so many words, stunned his head, “That these…Cylinder, piston or something, what is it for? ”

    “In order to build a machine that can move automatically.”

    The Steam engine brings the driving force needed for the first industrial revolution of mankind, completely liberating manpower and animal power.

    Its schematic is familiar to every mechanical dog. Simply put, it is an enlarged version of the kettle. The boiled steam is introduced into the cylinder, pushing the piston and the connecting rod to convert the thermal energy into mechanical energy.

    The principle is very simple, but it does not mean it is easy to manufacture. Its difficulty lies in the airtightness of the cylinder and the piston, as well as the manufacture of the gas pipe. When metal processing is not enough skill, it is a fantasy story to try to forge a qualified cylinder by hand.

    However, Anna’s ability to make up for the technical flaws.

    Roland only needs to design four iron plates of the same size in advance, let the blacksmith shop cast and polish them, then fix them with right angle plates, and then weld them with Anna to get square cylinders with extremely high rigidity. With the help of the witch, he didn’t have to build a cylindrical boring machine like a traditional production process to make a circular cylinder. The same is true for other large components, which can be made into small pieces and then spliced ​​together, so that even a small workshop like a blacksmith shop can work together to make all the parts needed for the Steam engine.

    In fact, before welding was invented, people could only connect small parts by bolts or riveting, and the inside of the cylinder must be smooth. Conventional connections obviously cannot do this.

    The only trouble is the gas pipe. Its production method is nothing special, burn a long iron plate to red heat, then put it into the groove mold, hammer it with a hammer and hammer to form, this is also the method of making the front gun barrel . However, the barrel still needs to be straightened afterwards, and the drill line is expanded, which is more complicated.

    The trouble is that Roland impossible to call the blacksmith to his back garden, the witch can’t be exposed for a while, and the iron is not his own strength. In desperation, he had to let Chief Knight do the work and command himself.

    After three days of tossing, Roland finally spelled out the first Steam engine in the backyard.

    “Is this your most powerful thing?”Carter frowned at this strange machine, and he first confirmed that it was not related to the cult ceremony. Every shovel above was put on by him and looked like a sealed stove. It would be unreasonable if Devil could be attracted to it.

    But how do you move a pile of shovel? It looks awkward and has no feet. Is it possible to fly?

    But in Roland’s eyes, this seemingly simple machine exudes the beauty of industry. Standing on the shoulders of the giants, he naturally did not take the Steam engine – Watt Steam engine – the route to improve the Steam engine. His first prototype was a high-pressure Steam engine with double-link and sliding valves. . Its production is no more difficult than the original Steam engine. The key lies in some innovative ideas.

    “You will know when you are.”

    Roland poured a bucket of water into the steam room and let Anna ignite the firewood.

    Ten minutes later, the water was boiled and the Qianlong curled up. Soon, there was a buzzing sound inside the cylinder, and Roland knew that it was the sound of the cylinder being heated and expanded. The iron plate of the piston is thinner, and the expansion variant is larger than the cylinder, and will eventually firmly adhere to the cylinder wall.

    “Is this not boiling water? I didn’t expect it to be a stove,” Carter muttered.

    When the cylinder was filled with steam, Roland was excited. The piston begins to push the link outward. When moving to the apex, the other link pulls the sliding valve, which in turn pushes the piston inward. The two connecting rods rotate with the wheels one by one, and as the firepower increases, the speed reaches a peak quickly.

    The machine made a harsh roar, and the exhaust snoring snorted and sighed with white air, and there was an unstoppable momentum.

    “This is what you said…The power hidden in nature? ”Anna asked dumbly.

    The Chief Knight was incredibly unbelievable. The last big iron wheel was built with great effort. Now it is spinning like a feather, standing on the side and even feeling the airflow from the wheels. This can only show that the strength of this shovel in front of it is so big that it is amazing.

    His bottom of heart gradually rose a little uneasy.

    His Royal Highness said that it can replace manpower and animal power. If it is not to lie to himself, when it replaces the horse to pull the chariot, it is because of this brute force that only ten Knights are hard to resist.

    It takes fifteen years to build a qualified iron furnace to train a qualified Knight, but it takes only three days. It took only a week to count the time the blacksmith built the parts.

    It does not require feeding, is not afraid of cold and hunger, and is not afraid of arrows and guns. As long as the front corner is fitted with a corner, it can slam on the battlefield.

    At this rateIs it necessary for the traditional Knight to exist?

*******************

    In the evening, when Roland returned to the bedroom, he saw Nightingale again.

    She didn’t wear Hood this time, sitting at the table with a smile on her face, and playing with a few pieces of parchment in her hand. “It seems that the rumor outside is really unbelievable. It is said that the Four Prince does not learn anything, and his character is bad. In fact, he does not make much more than the court master. What is drawn on this paper is the design of the iron stove? You call it…Steam engine, right? ”

    I am going, can you leave some privacy, if you want to come, you want to leave, you think this is your home! Roland’s heart was awkward, and the face still replied innocently. “It’s a design, but without Anna’s help, it’s just a drawing.”

    What it does

    “A lot, mining, drainage, smelting, forging, and wherever it takes a lot of effort, it can make a difference.”

    “Then I took it,” Nightingale rolled the sheepskin paper into the robes. “The Operation Association also has people who can control the flames.”

    Hello?

    She waved her hand and stopped Roland’s protest. “Of course, I am not taking your things in white. You should check this first.”She put a small group of white things on the table.

    Roland walked over and pinched it with his fingers and found that it was actually a roll of paper.

    He gently unfolded and swept his eyes. “This is…”

    “The secret letter used by the pigeons,” Nightingale said in a playful tone. “The recipient is your Head maid Tyre, hey, it seems that your harem is not stable.”

    “I haven’t touched her,” Roland frowned.

    Tyre, the woman in memory seems to have followed her very early. The original Four Prince was very interested in her, but she could not succeed in several harassment. This time, Border Town simply upgraded her to Head maid and waited for herself. Her room was arranged next door. Didn’t expect to be the eyeliner arranged by the Royal Brother Royal Sister?

    Although the letter was not signed, according to the content, in all likelihood, it was from the hands of the brothers and sisters. The letter said that the last failure made the owner very unhappy, and the next time he ran into Longsong Stronghold, he would never be allowed to fail again. Ok, in fact, you have succeeded, he thought, otherwise he will not become Roland Wimbledon.

    This letter is unlikely to be forged by Nightingale, because only those who participated in the plot will know the first assassination plan. And if Nightingale wants to kill himself, there is no need to be so troublesome.

    “You stole from her?”

    “Your Head maid is not that stupid. She is going to burn after reading it. It’s a pity that when she saw it, I happened to be behind her,” she made a bag-adjusting action. “So, what are you going to do? Need me to help “handle”? ”

    Roland naturally understood that the treatment in her mouth was What does it mean, hesitated for a moment, he finally nodded, “I am bothering you.”He really has no confidence in doing this kind of thing himself, “if you can…Ask me for who is the person behind her. ”

    “As you wish, Your Highness,” Nightingale smiled and bent down. “So, this scroll is a reward.”
