Two months earlier, the Asgardians, instigated by the Order, had gone to war against the Caucasus kingdom, which had been controlled by the revolutionary army. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

It was a doomed battle, at least at first, as everyone thought.

The disparity in forces between the two sides was huge, the Caucasus kingdom was losing one after another, the eastern and western fronts were completely lost, and the third army drove straight in, and at the most terrible time, it was only forty kilometers away from the capital of the Caucasus.

Sixteen days ago, however, overnight, the tide turned.

The weapon called 'Redemption' was loaded in the hands of 2,000 members of the revolutionary army, and three hours later, this army of farmers, craftsmen, bankrupt merchants, and landowners, led by old soldiers, wiped out the third army, the most elite of the Asgardians.

Sixty thousand elite soldiers are buried forever in the snow.

It's like a ridiculous joke.

In the ensuing war, Asgard, which ranked first in the West in terms of national strength, was defeated one after another, and in just two weeks, it lost the territory it occupied in the Caucasus, and did not even dare to fight a frontal war in a short time, so it could only impose an economic blockade on the Caucasus by sea in a roundabout way.

For a time, all nations focused their attention on that weapon called 'salvation'......

Through crude workmanship and rudimentary technology, what they saw was an almost infinite potential for war!

Within a month, no matter how the Holy City banned and denounced it, the research institutes of every country were crazy about it, and even after half a month, there were already imitations that were not inferior to the original.

It's like a noble and powerful knight who died under the bolts of a peasant's crossbow.

The way of war has begun to change.

This is just an omen.

Even though the Hundred-Eyed One was defeated, it was still not a complete defeat.

At the very least, he threw the abyss into the material realm, and completely liberated the increasingly powerful nations from the yoke of the Holy City, and the Third Amendment Act was already in name only.

It is clear to all that a turbulent year is coming.

The revolution has only just begun, and no one can imagine how many monsters can be bred in this world after breaking free from the guardianship of the Order......

Ye Qingxuan looked at the Stirling external combustion engine, and after a long time, he suddenly asked:

"What did you use as a working medium?"

Ronald was silent for a moment, then replied, "After trying various gases, we decided to use mercury that has been transformed into alchemy. ”

"Oh?"

Ye Qingxuan smiled: "Why?"

That smile made Ronald a little flustered for some reason.

He coughed twice, collected his thoughts, and then explained:

"First of all, alchemy mercury is very sensitive to temperature, as long as the boiling point is reached, two standard units of mercury can be evaporated instantly, and below the boiling point, it can be instantly condensed and cooled, as long as it is sealed, as a working medium to push the piston, it is simply perfect.

Moreover, the way it is produced is nearing maturity, although it is slightly more expensive than gas, but in the long run. It's much less than the resources it would take us to re-research and popularize production. ”

"Oh, value for money?"

Ye Qingxuan's eyebrows raised: "This is not the way of thinking of ordinary researchers, it seems that Director Ronald, your talent is not limited to a small researcher." ”

As he spoke, he patted Ronald on the shoulder and praised:

"Not bad. ”

Ronald smiled reluctantly and continued: "And, with the current design, we have the flexibility to replace the external accessories.

In this way, it can be driven by any fuel, and it doesn't matter if it is solid, liquid or gaseous, as long as there is a matching combustion furnace, we can achieve full compatibility. “

"Popularity has increased dramatically. ”

Ye Qingxuan nodded and applauded: "Perfect." So how to solve the most important noise link?"

Ronald laughed at the mention of this.

"There's no need to worry about that. ”

He pointed to the components of the external combustion engine and said: "The biggest natural advantage of the external combustion engine driven by the Carnot cycle compared to the original steam engine is that the noise will be greatly reduced, and as long as the most basic sound insulation treatment is done, it will not cause any ether reaction."

And most subtly, we use alchemy mercury. Alchemical mercury absorbs the noise of an external combustion engine and produces an etheric reaction on its own, adding thrust to the machinery.

The only drawback is that the start-up process requires a long warm-up, but the new cycle designed by our formula requires external combustion only during the warm-up phase, and once the body is in operation and enters the inertia phase, the alchemy mercury absorbs the noise generated during operation on its own and provides power.

Moreover, the efficiency exceeds 60% of the original body. We only need a very small supply of fuel to keep the cycle going.

Although we can't complete the miniaturization, we have an incomparable advantage over the Ethernet engine.

By calculation, at the same cost, the ether engine can only drive one armor, while our external combustion engine can drive an entire factory!"

Speaking of which, Ronald could no longer hide his ecstasy and danced with his hands.

Ye Qingxuan was not as excited as he imagined, but did not have the slightest smile, but just bowed his head: "So, let's start the experiment now, I can't wait to see it." ”

Ronald was stunned for a moment and nodded hurriedly.

Soon, the cart carrying the fuel was brought up.

For the sake of safety, the others all withdrew dozens of meters away, and only Ye Qingxuan was able to stand in front of the external combustion engine.

Despite all the uncertainties surrounding the prototype, he didn't believe that a runaway external combustion engine had the ability to cause any damage to himself. It's just kidding, what neither the Hundred Eyes nor Arthur can do, if a broken machine can do it, then it can do a natural disaster.

After waving his hand and signaling Ronald to start, Ye Qingxuan waited quietly.

Ronald hesitated for a moment, then swung his shovel and lamely added coal to the combustion furnace of the external combustion engine, spending a few minutes before and after scattering it all over the ground.

Soon, after the refilling, a blazing flame rose in the burner.

Ronald in front of the furnace was already sweating.

Five minutes later, the huge external combustion engine after the preheating began to tremble slightly, like the low sound of a swarm flapping its wings, Ye Qingxuan heard the muffled sound of the piston running rapidly in the core.

Launched!

Alchemical mercury evaporates and expands, pushing the piston to run, and then condenses into a liquid again with the cooling flow at the other end, shrinking.

Huge power is born from the cylinder with the operation of the prototype, and it is continuously transmitted along the cables and mechanical structure, driving the large lathe that is the subject of the experiment in the distance.

The gearbox was running low and fast, the muffled sound of steel clashing and rubbing sounded, the lathe trembled, and the gears were running, and the headstock began to run.

The transmission chain began to rotate, and the solid pieces of steel were transported to the front of the tool holder, and there was a sharp sound, and in the loud and piercing sound, the steel was cut rapidly.

Everyone held their breath.

The heavy piece of steel is cut under the alloy turning tool, and after a dizzying series of intricate processes, a grinding and polished hollow steel shaft rolls off the transmission chain to the ground with a crisp sound in a few seconds.

The tester risked running up in small steps, pulling out various tools to check, and at the end, he raised his head excitedly and waved his hand in ecstasy.

Qualified!

At that moment, the suffocating atmosphere was broken, and all personnel let out cheers. The external combustion engine has finally taken its first steps and proved its industrial potential.

In the midst of the cheers, Ye Qingxuan suddenly stretched out his hand, directly skipped the control equipment in the test field, and pulled out a large amount of ether from the sea of ether, and the silver streamer rushed in.

In the snap of a finger, the alarm sounded.

In front of him, the location of the external combustion engine rose from a pure white area to a yellow area representing hidden dangers, and the external combustion engine shook and continued to operate, and even accelerated.

Five minutes later, Ye Qingxuan waved his hand again, and the ether density climbed straight up.

Red Zone!

The external combustion engine shook violently, bursting into a muffled sound, causing the aether in the air to burst into streamers, and countless ripples expanded and spread out to each other.

But it's still within the safe zone.

Under the influence of the external environment, the stability of the external combustion engine plummets, and even cracks appear on the main compartment of the body. Behind him, the researchers who watched from afar swallowed and spat, praying desperately for the external combustion engine to run steadily.

However, the noise is getting louder and louder, and the loopholes of the prototype are exposed.

The lack of perfect sealing caused the operation of the fuselage to be affected by the external environment.

Ye Qingxuan pondered for a moment and waved his hand again.

Black Zone!

In an instant, a loud roar erupted, and shattered gears flew out of the casing, tearing huge gaps in it. The gear fragments roared and stopped abruptly in front of Ye Qingxuan.

It was just an inch away from piercing his skull.

Everyone gasped.

The external combustion engine roared, gushing out a large amount of evaporated alchemical mercury, and then fell silent.

With its stoppage, everyone's faces turned pale.

Failed.

But in the silence, there was the sound of applause.

It's Ye Qingxuan.

He clapped his hands, stared at the broken external combustion engine in front of him, and smiled, full of joy:

"Very good, very good, I should say, beyond my expectations!

Mr. Ronald, what you and your research team have produced will shock the whole world!"

Ronald looked at him stunned, for a long time, and asked hesitantly:

"But it wasn't just now...... Is it broken?"

"The black zone is a forbidden area for machinery, except for a few simple machinery that can run stably, there is no condition for the operation of large construction machinery, right? Not to mention that there is no prototype that has been tested and inspected, it is already unexpected to be able to do this degree. ”

Ye Qingxuan shrugged: "Besides, I never thought of it running in the black zone, and even the red zone was not considered. It was originally a production machine, and it was never something to be developed. As long as it can operate smoothly in both the white and yellow zones, it has met all production needs.

It's good to be able to do that, no, it's unbeatable, Mr. Ronald, and I'm looking forward to the day when it's officially produced.

I hope you don't slack off and can keep up the good work. ”

As if returning from hell to heaven in an instant, Ronald nodded in ecstasy, hugging and cheering with the other researchers.

This reaction made Ye Qingxuan a little helpless, he made himself look like some kind of tyrant, couldn't he kill them all?

He shook his head and looked at the shattered external combustion engine in front of him.

I couldn't help but marvel at my eyes.

It's not because I'm stunned by its results, it's not that I didn't anticipate its effectiveness. On the contrary, as the first person to come into contact with its principles, Ye Qingxuan had already been mentally prepared.

It's just that, through the crude prototype, what he sees is not just a rudimentary prototype engine, but near-perfect ideas and ideas.

The Royal Academy did better than he could have imagined.

Its designers, like art, have mastered its principles to create the most perfect prototype, like invisible hands delivering embryos that are still in gestation.

Now, the newborn has come into this world, although it is a little weak, but the future is destined to be great.

It's a genius idea.

Soon, it is foreseeable that horse-drawn carriages will be obsolete, and the huge machinery with the addition of the Stirling external combustion engine will pull hundreds of carriages on the tracks.

Immediately after that, the production industry and industry will also usher in earth-shaking changes, and a large number of manpower will be liberated from the complicated and simple work......

The world is about to change even further.

Ye Qingxuan laughed silently.

－

After a short celebration, the researchers showed Ye Qingxuan its design drawings and a large number of application plans. Just by looking at the thickness, you can feel the effort they put into it.

"By the way, I remember you said that you have completed the main cycle with a new formula on the original basis, so that alchemical mercury can steadily absorb noise and convert it into power.

Now it seems that the efficiency of the entire external combustion engine has almost doubled, which is really a genius idea...... What kind of formula, exactly?"

Ye Qingxuan flipped through the design drawings and asked casually, "I'm a little interested in this, can you explain it to me?"

For a moment, the atmosphere seemed to freeze.

The researchers looked at each other and finally looked at Ronald, whose expression stiffened slightly, "Huh...... This ......"

"Ah, I found it. ”

Ye Qingxuan took out a drawing full of complex numbers from it, looked at it with a smile, admired it from time to time, and finally, raised his head and pointed to a few values in the corners:

"Excuse me, how are the variables here and here solved? I don't understand, how is this result calculated?"

Ronald was silent, swallowed and foamed, and at some point, he was already sweating.

"What's wrong?"

Ye Qingxuan raised his head, and his smile was still the same: "Mr. Ronald, you seem to be a little uncomfortable?"

"It's here...... Some are too hot. ”

Ronald smiled reluctantly and tugged at his tie, "It's so hot." ”

Ye Qingxuan didn't speak, just smiled and looked at him.

Looking at it, Ronald's face became more and more pale, and he couldn't suppress the trembling of his legs, until finally, he was almost unsteady on his feet, and he sat down on the ground.

"Eh, I'm a little dizzy. ”

He smiled awkwardly and tried to get up, but his arms trembled: "What did you just ask? I'll explain it to you......

But Ye Qingxuan stopped laughing.

He shook his head, sighed, and threw the blueprint in his hand onto Ronald's.

"Come on, sir. Lying is a trick, and it's not for you. ”

He crouched down, looked into Ronald's eyes, and asked softly:

"Tell me, where did the formula come from?"

Ronald's expression twitched, and he defended himself upside down: "The time is too short, your requirements are too demanding, and we are forced to ......"

"I understand that a month is simply unkind. ”

Ye Qingxuan nodded, and his voice was soft:

"But if you don't, how can you go to Newton for help?"
