Chapter 327: Active Black Dragon

"You, put these two pieces of iron together." Heilong said, beneath the huge body were a group of silent casters and red lotus goblins.
The caster nodded, holding the two iron plates, the flames spouted between the fingers, and the interface melted at a speed visible to the naked eye.
"That's it, reduce the magic, and do it again on the back."
As the caster did, the two iron plates were spliced ​​together at ninety degrees and welded together firmly.
This is not difficult. Any caster with a certain level can do it, even Caesar himself. This psionic black dragon already has the ability to distort matter by will.
Caesar glanced at the interface. Longan's fine vision allowed him to clearly see the changes at the interface. A flawless perfect weld suddenly appeared. If it was slightly polished, the traces of the metal fluid during the melting of the iron were polished and polished. The plate is almost indistinguishable from a once-formed forged body.
In the welding field, it is quite difficult to achieve a smooth and seamless weld joint, but everything is solved by relying on supernatural power.
"Good job." The Emperor Black Dragon did not hesitate his compliment: "Next, also weld the other two iron plates."
"what is this?"
Luna emerged from his head and asked, "A metal ... bucket?"
"No, this is a cylinder." Caesar corrected.
"Cylinder?" Luna repeated in confusion, looking at the welded barrel, which was just enough for her to take a bath.
"You can think of it as a component of the core of magic."
Caesar said, looking at another square iron plate: "Did you see the small hole above? Air will enter the cylinder from here and push the piston. A piston is an iron piece slightly smaller than the inner diameter of the cylinder, which can be free inside. motion."
"Caesar, you make new words."
Even though she was used to it, Luna was still a little bit dizzy. At this time, letting a master who studies magic guides listen to the black dragon ’s explanation is almost the same. The little guy is difficult to understand:
You ca n’t directly tell me what this thing is for Is it also an explosive weapon? "
"No, this is a production machine."
The emergence of the steam engine, the most iconic invention of the earth, has brought about the driving force needed for the first industrial revolution of the earth. After that, the civilization of the earth has increased productivity with a near-leap attitude, and liberated manpower and animal power.
The inspiration for making steam engines came from the Red Lotus Goblin. A considerable number of them were timid like rats. They were not interested in weapon development and did not dare to continue research on gunpowder. Instead, they were about the lid of the kettle that constantly jumped when boiling water. Full of curiosity, he secretly researched in private, and as a result, the frypot incident occurred, which alarmed the black dragon emperor.
Caesar was ready to shock the world by hand, and talk about the steam engine first.
Its principle is not complicated. In simple terms, it is an enlarged version of the kettle. The boiled steam is introduced into the cylinder, which pushes the piston and connecting rod, converts the thermal energy into mechanical energy and then outputs it.
The principle is simple, but it does not mean that it is easy to manufacture. The difficulty of this mechanical part lies in the tightness of the cylinder and the piston, and the choice of the material of the transmission pipe. Before the metal processing level has reached a certain level, we want to make a perfect cylinder. Heaven and earth, the Red Lotus Goblin died on it, but they didn't realize the problem.
The real appearance of the steam engine is not easy. On the earth where Caesar is located, it also came into being at the right time after the development of civilization to a certain degree and sufficient technical reserves.
But in a world where cylinders can be welded by hand and rubbed by hand, manufacturing problems can be easily bypassed and solved.
Caesar only needs to design four iron plates of the same size in advance, give a design drawing, and then let the goblin factory finish casting and grinding. Then, by magic welding and then fixing the shape, a molded cylinder can be obtained.
But this does not mean that everything is fine, there are still troubles to deal with. The square cylinder cannot solve the problem of stress stability. The force in the cylinder is concentrated at the four corners. Even when the piston is acting at high speed, it does not consider the vibration of the machine itself. It is enough to destroy the weld and it is extremely difficult to maintain air tightness.
Under normal circumstances, if you want to solve this problem, you can only change the design, or choose a higher strength material.
It is impossible to change the design. It is impossible to change in this life. There is only this thing in Caesar's mind, and he cannot get it any more.
Higher-strength alloy materials depend on the development of physics and chemistry. Other Eladia countries and the Black Wing Empire do not follow the same path. This material cannot be imported. The Empire needs to use money to accumulate data. The library can only be manufactured after a large number of matching experiments in the laboratory have succeeded.
Without the help of these supernatural forces, Caesar may have to wait a little over a hundred years, but now, Caesar can let the casters use magic blessing to increase strength and maintain stability, and make the current steam engine similar to The same thing as an enchanted creation.
Of course, this does not mean that the steam engine always needs to rely on supernatural powers, just like toddlers need toddlers. After the baby grows up and the scientific level of the empire gradually keeps up, the steam engine can get rid of this constraint. It can be made and run normally even without a caster.
So several casters, a group of red lotus gnomes, and their affiliates accompany the black dragon emperor to play with him for two days, and finally built the steam engine in the arsenal camp.
In fact, there is a tool to replace the steam engine in Elladia. That gadget was named by the scholars as the core of magic energy. When needed, the magic power stored in it is converted into power output. The performance is consistent with the properties of the steam engine and more Efficient and portable.
However, due to the high cost and difficult production, all this kind of stuff is used by the ruling class, and wanting to mass produce is almost a fable.
"Your Majesty, this is what you said ..."
The half-lich Ryan looked at this strange machine with suspicion. It looked like a sealed furnace, covered with various pieces of iron goblets, and looked a bit deformed. Although it was blessed by magic, it was all It's some simple stability control magic.
How can it move without the core of magic being installed? Could His Majesty still give it life? And this thing seems awkward, do you have hands, feet, wings, and in what way?
"Hum."
However, in the eyes of Caesar's sense of superiority, this seemingly humble machine exudes an alternative beauty, which is the taste of industry, the fragrance of capital, and the foresight of the rise of the Black Wing Empire. This country is destined to go Another way.
He told the goblins to pour two buckets of water into the steam room ~ EbookFREE.me ~ and then lit the firewood below.
Soon the water was boiled, and grunted and rolled up, and the crackling sound gradually started in the cylinder. It was the sound of the cylinder's thermal expansion. The piston was relatively thin. The expansion deformation caused by the heating was larger than that of the cylinder, and it would eventually be firm. Abut on the cylinder wall.
The hesitation of different casters, after seeing this scene, the red lotus goblins gleam with a shining light, this is the scene of their experiments at that time, these little guys hurried forward, trying to get closer and observe carefully .
When the cylinder is filled with steam, the door of the new world is opened, and the piston starts to push the connecting rod outward. When the movement is reached, another connecting rod pulls the sliding valve, and the steam pushes the piston inward again. The two connecting rods One round at a time, fast movements, the installed rollers spin quickly, and as the fire power increases, the speed quickly reaches its peak.
The machine made a sharp squeaking sound, and the exhaust port purred and sprayed with white mist, which had a shocking momentum.
"What is this ...?"
Ren asked blankly, as a half-lich who studied the spell, even if he saw it in his own eyes, he still didn't understand what caused the "iron furnace" to move.
