I became a witch, but I started the industrial revolution

"The Orc Empire has more fighting races. With yours, I think I have completed the Orc tribe encyclopedia~"

Elsa looked left and right, and exclaimed in amazement from time to time, especially when she looked at the passing orc lolis with fiery eyes from time to time...The furry ears on the top of their heads scared every little baby who passed by them so much that they covered their heads.

Even the kitten adopted by Medea was lying on her chest trembling and not daring to move.

Chapter 102: Gunpowder? A strange and ingenious technique.

Main Continent

Kingdom of Puerente

Royal Academy of Magic Alchemy

"boom!"

A crisp gunshot rang out in the shooting range of the institute.

Looking at the light on the target, the dean of the Royal Academy frowned. He turned to look at the dean of the Alchemy Academy who had put down his gun and was reloading: "Level 2, is this the weapon you mentioned that has emerged in the subcontinent? Is it worth wasting my time with such power?"

The king, who was visiting the place, heard that there was some new stuff and came to see it. After seeing its power, he was a little disappointed. A casual spell from an intermediate magician could have such power.

And looking at how slowly the Dean of the Alchemy Academy reloaded bullets...if it were a magician, he would have probably fired three magic bullets in that time, so there would be no way he would give the opponent so much time.

"and many more..."

The dean of the Royal Academy suddenly realized something and after carefully feeling it, he came to the conclusion: "This thing has no magical fluctuations?!"

The king also became interested after hearing this. He took the gun from the other party and, under his guidance, ignited the match and fired a bullet: "Oh my! You really don't need magic power. Interesting~"

"Yes, Your Majesty. It is not the magic elements that stimulate the energy, but the black powder inside. It is called black powder."

The dean of the Alchemy Institute picked up the small cloth bag and poured the black powder from it onto the table to show the two people: "This is not a product of alchemy. It is just a mixture of various inconspicuous natural products in the world. It will explode violently when it encounters open flames."

"And the mortals in the subcontinent bound them in iron pipes, using them as the propulsion energy for the marbles and turning them into offensive weapons for the military to use."

The Dean of the Royal Academy lit a flame on his fingertips, which touched the black powder on the table. With a bang, the powder quickly burned and emitted a large amount of smoke: "Interesting~"

"but...."

He shook his head in contempt. "It's just mortal wisdom. Energy is too complex and its form is too single to be transformed. It is totally incomparable to the plasticity of magic."

The king played with the crudely shaped matchlock in his hand, and laughed at the matchlock that was slowly burning and emitting white smoke: "Can this be used by the army? What a strange and ingenious trick."

"Although I am a little surprised that such a thing was created, it is still futile for civilians to use it to fight against magic. It cannot change anything. The mecha soldiers will be killed as many as they can cover with a range magic."

The dean of the Royal Academy nodded in agreement. Although the power was quite impressive, it was only at the level of an ordinary low-level or mid-level magician.

Even the most common soldiers in the kingdom’s army are at the intermediate level, and after putting on magic armor, it is very difficult for such weapons to even break through their defense.

But the dean of the Alchemy Academy who brought the muskets didn't think so: "Although these things can't pose any threat to us, their creativity makes me feel a little uneasy..."

"They completely abandoned the magic route and developed a weapon of this power. A new kingdom rose in the subcontinent because of the emergence of this weapon. This is something we should be vigilant about."

The scene fell silent. The emperor looked at the matchlock gun and pondered what the dean of alchemy had said. Suddenly, as if he had thought of something, he asked, "Did the steam engine that doesn't require magical elements also come from the subcontinent?"

"Yes..."

Hearing the answer, the king narrowed his eyes, he felt a hint of threat from these things.

At this time, the president of the Royal Academy stepped forward and said, "I have also seen those so-called steam engines. The outer shell is just a piece of iron that an ordinary blacksmith can hammer out, and the steam inside is also water vapor."

"Like these so-called black powders, they are all very common materials in nature. The mortals in the subcontinent are used to primitive life. Maybe they still climb trees to pick fruits to eat. Hahaha, it is very normal for them to accidentally discover these materials in nature."

"Mortals in the subcontinent have lived for thousands of years, and this is the only thing that can cause minor damage to a magician. A magician can be killed with a flip of the hand."

Hearing the words of the Royal Dean, the king's vigilance immediately disappeared and he laughed: "That's right, thousands of years of development is just like this. Without magical talent, they will never be able to compete with magicians."

The dean of the Alchemy Institute also felt that what the two said made sense. He looked at the musket handed back by the king, and then thought about the magic machine that was more than ten meters high and driven by the king. He shook his head and stopped worrying about it:

"Your Majesty and the dean are right. I am making a big fuss."

"Well... don't worry too much about the subcontinent, they are just a bunch of uncivilized barbarians. Our focus now should be on our 'good' neighbors, whose hands are starting to get dirty again."

"Hmph, these hairy, dirty orcs have become more and more unscrupulous recently. It seems that they have forgotten how it felt to be chopped into pieces by the mecha army!"

At this time, the "female barbarian" leader Medea was taking Elsa to visit the secret experimental base of the Seris Federation, where all the current experimental-level black technologies in Seris were gathered.

Some cannot solve the material manufacturing costs, some can only make noise, and some are simply disposable consumables. In any case, they are technological creations that cannot be taken out of the laboratory in a short period of time.

Medea brought her here to visit, not only because these strange things themselves were interesting, but also to send a signal to Elsa.

See, I trust you so much that I even open up my most secret secrets to you.

She wasn't afraid of messing up and having the information leaked by Elsa. First, even someone like her who had direct insight into future technology and knew the outcome, the countries she controlled couldn't meet the technological requirements, let alone outsiders.

Second, because they are naturally on the same front, there is no possibility of betrayal

Strictly speaking, the witch clan is a large and extremely closed family. She has to demonstrate her own value in order to get more care and resources from the family.

Just like the last time the Federation was attacked by the Iron Giant, if it weren't for Shirley, she and a group of ordinary soldiers would have to die before the attack could be resolved.

Apart from anything else, just having two more white-haired people as guests in Seris would be like a piece of meat bun delivered to your doorstep if the enemy causes internal trouble in the future.

Many black technologies are actually creations of magic, such as the magic rifle that Mi Wei now carries with her like a baby.

This combination of magic and technology is extremely dark whether in this world or in the previous life. All theories and data are obtained through laboratory experiments bit by bit, and no one can provide help.

In addition to those black technologies, there are also some experimental-level technological creations that cannot be mass-produced for the time being, but prototypes have already been made.

For example, the magic engine, which is the previous engine that relied on the explosive spray of magic dust to increase the power stroke, was sealed because it could not be mass-produced due to the difficulty of cylinder manufacturing and the energy requirements were too harsh.

The sealing technology is just not produced in large quantities. Media has never stopped investing in technological upgrades. It has now achieved an inline 6-cylinder engine like a mechanical piston fuel engine, and also has an experimental prototype of a turbocharger.

But these little gadgets are not the point. What she wants to show Elsa is a huge monster.

A real big one!

【Airship】

Chapter 103 Black Technology, Airship

The two of them took a car to a huge warehouse located in the valley. Why is it called huge?

Because its land area completely fills the entire valley, the entrance of the valley is where its gate is located.

As the doors were opened and closed one after another and they walked inside, Elsa, who had been careless, looked at the huge structure in front of her, which she could not even see the top of when she looked up, and her eyes widened.

"The Seris airship is 128 meters long, with a full rigid frame and seven helium-filled airbags inside. It has a diameter of 15 meters, four on the top and six on the bottom. It has four parallel-cylinder magic engines that can turn 6 degrees. It has a speed of 365 kilometers per hour, a flight altitude of 4 meters, and a load capacity of 60 tons."

Medea walked to the bottom of the airship with his hands behind his back, looked up at the airship that was so tall that he couldn't see the top, his eyes were full of heat, the propeller fighter was simply weak in front of it.

Reality is so magical. With the same level of technology, we can only make biplane propellers on airplanes, but once we open our minds, the technical difficulty of airships is actually similar.

After all, the flight control systems such as rudders are common to airships and airplanes, except that airships use steel cables for transmission.

Where are the difficulties of airships?

Aerodynamic shape?

When the airship was first developed, after summarizing a large number of accidents, the olive-shaped shape was finally adopted. At the same time, the use of airbags was changed to modular independent airbags after a large number of tests.

Fire and explosion?

Hydrogen, which is easily flammable, is also the cause of frequent fire accidents. Helium is safer and more efficient. However, the value of helium was too high in the past, and few countries could afford the cost of using helium in manufacturing airships.

But she didn't care! She had all the helium in the world at her disposal.

Helium can be extracted from natural gas. Helium is extremely active. Other gases will basically be condensed into liquid under cooling and condensation. Only helium can remain in a gaseous state, thus completing the initial extraction.

Secondary processing and purification uses activated carbon for further purification before use.

Its nearly 5000-meter altitude ceiling also made it invincible at high altitudes. Not to mention ordinary magicians, even she could only watch and get beaten on the ground.

Even though it is covered with airbags, its external metal frame and distributed airbag design may not be able to do anything to it even if it is shot by a large-caliber heavy machine gun.

If you want to kill it with one shot, you have to be at least at the Saint level.

Moreover, this 100-plus meters is only for the initial trial production. Once it is verified to be feasible, the diameter can be doubled, doubled again, and doubled again!

Airships are different from airplanes, and are designed based on the same concept as ships. Theoretically, as long as the volume does not reach the limit, the larger it is, the more economical it will be. In calculations, it is safe within a diameter of 500 meters.

"How about it? Do you want to try to sit on it?"

Aisha swallowed and said, "This... this can move?"

"nonsense!"

Mitia rolled her eyes at her and said, "I brought you here because we're going to take off for the first time. Why would I bring you here if you can't move?"

Since it was not filled with hydrogen, there was no risk of explosion. Having experienced actual experience with it in her previous life, Medea had no fear of this big thing, but was more curious about it.

Unfortunately, although airships are good in every way, they have high requirements for weather. For example, they are not suitable for taking off on windy and rainy days. They are also extremely afraid of sudden crosswinds, which can easily disrupt the balance of their flying posture.

As the test flight team boarded the airship and entered the cockpit and power compartment one after another, the two also boarded the airship.

At this time, the airship was in a state where gravity and buoyancy were relatively offset, and it was suspended at a height of two meters above the ground.

As the roof of the warehouse was opened under hydraulic power, a large amount of ballast water inside the airship was discharged. The four propellers located at the lower middle section turned upward, and the hull began to slowly float up and leave the warehouse.

The ascent was perfect as the weather was good so there were no unexpected events.

The airship remained suspended until it reached the predetermined ceiling of 4500 meters, and there were no problems with the entire structure.

In fact, the design ceiling of the submarine is around 5000 meters, but there is no need to reach such an extreme. Basically, above an altitude of 2000 meters, the people below are already out of sight.

Elsa has been observing the operation of this big guy with curiosity, her face full of disbelief.

As a dragon girl, she could naturally fly and could fly to such a height, but she had never imagined that a group of useless people who didn't even have much magic power and whose lives were ridiculously short could actually create such a miracle.

Hearing the cheers coming from the cockpit and engine room, and looking at the clouds outside the window, Elsa finally exclaimed: "It's incredible..."

"What do you think about using this as a mobile aerial warehouse and dropping a bunch of bombs on the enemy's heads?" Medea suddenly said with his arms folded.

"...Your idea is a bit bad!"

'But it is indeed very feasible. No one and no weapon can attack it at this height. This height is even more disgusting to me. The magic power consumption is too high. It is not worth it.'

'But how do you get this down?'

"Well... it's going to be slower to descend... we have to inject compressed air into the small airbags inside the airbags to increase the density of the airbags, and the propellers have to work in reverse to increase the thrust. Overall, it consumes a lot of energy."

Medea touched his head. The issue of raising and lowering airships was a thorny problem in his previous life. It was easy to raise them and to move them, but it was difficult to lower them.

After all, if you raise it up, you just need to add water, but if you lower it down... No! If you lower it, you just need to add water!
