Black Dragon Code

"You, put these two pieces of iron together." The black dragon said, under the huge body, there were a group of silent spellcasters and red lotus goblins.

The caster nodded as he said, and held the two iron plates, flames spewed out from between his fingers, and the joints melted at a speed visible to the naked eye.

"That's it, reduce the magic power, and do it again on the back."

The caster did so, and the two iron plates were spliced ​​together at a 90-degree angle and firmly welded together.

This is not difficult, any spellcaster 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 joint. Longan's fine vision allowed him to clearly see the changes at the joint. A flawless and perfect weld suddenly appeared. If it was polished a little, it would polish and polish the traces of the metal fluid when the iron was melted. Two pieces of iron A plate is almost indistinguishable from a forged body formed in one shot.

In the field of welding, it is quite difficult to achieve a smooth and seamless weld, but everything can be easily solved by relying on supernatural power.

"Good job." The Black Dragon Emperor was not stingy with his praise: "Next, weld the other two iron plates."

"What's this?"

Luna popped out of his head and asked, "A metal...barrel?"

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

"Cylinder?" Luna repeated in bewilderment, looking at the welded barrel, which was just big enough for her to bathe in.

"You can understand it as a part of the magic core."

Caesar said, turning his eyes to another square iron plate: "See the small hole in the top? The air will enter the cylinder through here and push the piston. Well, the piston is a piece of iron slightly smaller than the inner diameter of the cylinder, and it can move freely in it. sports."

"Caesar, you made up a new word."

Even though she is used to it, Luna is still a little dizzy. At this time, it is almost the same for a master who studies magic to listen to the black dragon's explanation. It is difficult for the little guy to understand: "You can't just tell me what this thing is used for. Is it also an explosive weapon?"

"No, it's a production machine."

The steam engine, the most iconic invention of the earth, its appearance brought the driving force needed for the first industrial revolution on the earth,

After that, the earth's civilization increased productivity in a nearly leap-forward manner, liberating manpower and animal power.

The inspiration for making a steam engine comes from the red lotus goblins. A considerable number of them are as timid as a mouse. They are not interested in weapon research and development, and they dare not continue research on gunpowder. Instead, they are interested in the lid that keeps jumping when boiling water. Full of curiosity, he conducted research secretly in private, and finally came up with the frying pan incident, which alarmed the Black Dragon Emperor.

Caesar is also ready to shock the world, let's get the steam engine out first.

Its principle is not complicated. Simply put, it is an enlarged version of a boiling kettle. The boiled steam is introduced into the cylinder, and then pushes the piston and connecting rod to convert heat energy into mechanical energy and then output it outward.

The principle is simple, but it does not mean that it is easy to manufacture. The difficulty of this mechanical part lies in the airtightness of the cylinder and the piston, as well as the selection of the material of the transmission pipe. Before the metal processing level has reached a certain level, it is necessary to manufacture a perfect cylinder. The Arabian Nights, the red lotus goblins also died on this, but they didn't realize the problem.

It was not easy for the steam engine to come out. On the earth where Caesar lived, it came into being at the right time after the civilization had developed to a certain level and had sufficient technical reserves.

But in a world of bare-hand soldering and hand-kneading cylinders, manufacturing problems can be easily bypassed and solved.

Caesar only needs to design four iron plates of the same size in advance, provide the design drawings, and then let the goblin factory cast and polish them, and then fix the shape through magic welding, and then the formed cylinder can be obtained.

But this does not mean that everything will be fine. There are still troubles to be solved. The square cylinder cannot solve the problem of stress stability. The force in the cylinder is concentrated and distributed at the four corners. It is enough to destroy the weld, making it extremely difficult to maintain air tightness.

Under normal circumstances, the only way to solve this problem is to change the design or choose a higher strength material.

It is impossible to change the design, and it is impossible to change it in this life. Caesar only has this thing in his mind, and he can't get any more.

Higher-strength alloy materials depend on the development of physics and chemistry. Other countries in Elradia and the Black Wing Empire are not following the same path. This material cannot be imported, and the empire needs to spend money and time to accumulate materials. The library can only be manufactured after a large number of matching tests in the laboratory are successful.

Without the assistance of these supernatural forces, Caesar may have to wait a hundred years, but now, Caesar can allow spellcasters to use magic power to increase strength and maintain stability, making the current steam engine similar to The same thing as enchanted creations.

Of course, this does not mean that the steam engine always needs to rely on supernatural power, just like a toddler needs a walker. After the baby grows up and the scientific level of the empire gradually catches up, the steam engine can get rid of this constraint. Can be built and run normally even without a caster.

So several spellcasters, a group of red lotus goblins, and affiliated organizations played around the Black Dragon Emperor for two days, and finally assembled the steam engine in the arsenal camp.

In fact, there is a tool to replace the steam engine in Elradia, which is named by scholars as the "magic energy core". When needed, the magic power stored in it is converted into power output. Efficient and portable.

However, due to the high cost and difficulty of production, all such things are used by the ruling class, and it is simply impossible to mass-produce them.

"Your Majesty, this is what you said..."

The demilich Ren looked at this strange machine with doubts. It looked like a sealed furnace, covered with iron lumps assembled in various pieces, and looked a bit deformed. Although it had been blessed by magic power, it was not is some simple stability control magic.

How can it move without placing a magic core? Could it be that His Majesty the Emperor can still give it life? And this thing looks very clumsy, does it have hands, feet, wings, and what kind of movement does it have?

"Humph."

However, in the eyes of Caesar full of superiority, this seemingly simple machine exudes a different kind of beauty. This is the taste of industry, the fragrance of capital, and it is also the harbinger of the rise of the Black Wing Empire. another way.

He had the goblins pour two buckets of water into the steam room, and light the fire below.

Soon the water was boiled, gurgling and tumbling, and the crackling sound gradually sounded in the cylinder, which was the sound of the cylinder body being heated and expanded. The piston is relatively thin, and the expansion deformation caused by heat is greater than that of the cylinder body, and it will eventually be firm. against the cylinder wall.

The hesitation of different spellcasters, after seeing this scene, the eyes of the red lotus goblins burst into shining light. This is the scene of their experiment at that time. These little guys hurried forward, trying to get closer and observe carefully. .

When the cylinder is filled with steam, the door to a new world is opened, 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 back inward, the two connecting rods Moving fast back and forth, the additional rollers rotate rapidly, and as the firepower increases, the speed quickly reaches its peak.

The machine made a sharp piercing sound, and the exhaust port sprayed white mist, which was shocking.

"This... what kind of power?"

Ren asked blankly, as a semi-lich who is proficient in spellcasting, even if he saw the whole process with his own eyes, he still didn't understand what drove this "iron furnace" to move.
