Accompanied by "the prospective fiance" Dusand, Lorraine and her parents successfully met in the glass corridor outside the dance hall. Dusand, who was in charge of accompanying him, received a long time of performance-oriented concern from the "the prospective mother-in-law" under the corridor.

He performed with the most appropriate response and smile for two quarters of an hour, and a layer of sweat appeared behind him before Dusand was able to get out.

After saying goodbye to the Lorene family, Dusander walked through the crowd in a mess and finally entered the dance hall. He could no longer wait to come and see the "invention" first.

"This is...'the most important invention of this era'?" With her own only son of Baroness Androni and "the innate curiosity of a child who is only ten years old", in the lounge in the dance hall, Doosand successfully obtained the first license to take a look at the invention.

In the center of the lounge, an iron table with a distinctive difference from the gorgeous environmental style appeared suddenly. On the table was a metal creature with a strange appearance.

The upper part of this piece of metal is cylindrical, and there are four brass pipes on both sides of the cylinder. The lower part of the metal is closed by a square iron box. On the outside of the box, there is a metal wheel about the same size as a steam carriage wheel.

The inventor of this strange creation stood next to the table, preparing to answer the visitors' questions.

"Yes, Mr. Lord." Although he was named Dusande, he is only ten years old, his title still needs to follow the provisions of the Imperial Code - only aristocrat with the title of Baron or above can call him "Dear Dusande" or other more "intimate", which is in line with the name of a ten-year-old boy.

As the inventor of this machine and as one of the few women in the entire empire who received higher mechanical design education, Polina, who had no noble status, still needs to call the little brown-haired boy in front of her "Lord", and also needs to lift up her skirt, bend down and bow down to salute.

However, these little things are not important to Polina. In fact, even the fact that she was forced to leave her studio in Orlyn forever and came to Newell alone... is not that important.

She had always been eager to get funding from at least one or two nobles. Whether the other party saw the potential of the invention or was interested in something else she had...

Only when she gets the funding can she continue to improve her invention.

Polina firmly believed that her invention was enough to change the world, and even to be permanently recorded in history like Wald invented and improved the steam engine.

I hope that this young Lord can correctly realize his ignorance, rather than slander his inventions like those of Olin's great technicians.

She sighed in her heart. If the little lord was a little older, she might have used some other methods to gain the other party's favor.

Because he refused to admit defeat, he entered the field of mechanical design, which was "exclusive to men", but he needed to rely on his body to gain recognition... This method seemed completely a shame to Polina.

But in order to get funding, she had no room for herself.

Polina's psychological activities are wonderful, and Dusand's expression is also wonderful.

"It looks like some kind of power device." Dusander carefully observed the "equipment" for a long time, then suppressed his shock and asked his own question with a natural curious expression, "These brass tubes should be the ones that provide fuel? There are some oxidation marks on the outside of the pipeline. Are you using some kind of fuel with a higher temperature?"

Polina's originally gentle expression suddenly stiffened, and she slowly widened her eyes.

"You sealed the main moving parts with a black metal plate with hinges, which must be to wait for the other lords to open them when they point out that 'This is just a small steam engine', and to get a lot of amazement. This idea is good and dramatic."

Dusand continued his analysis, his mouth slightly raised, as if he had seen the upcoming scene of pretending to be slapping in the face. He continued, "In fact, the movement of this power unit does not require steam to be produced by heating water - the fuel input from the pipeline will expand rapidly through combustion inside the machine, which is the core driving force for its operation."

Polina's expression became even stiffer. She was like a robot without lubricating oil. She slowly turned her head and looked at Dusander. Her lips, which were wearing lipstick, opened and closed several times, but she couldn't say a word.

Dusander had no time to appreciate the other person's surprise now. He was indeed shocked by the product that suddenly appeared in front of him.

According to the history that Dusand was learning before, the human science and technology tree in this world is completely different from the world in his previous life. An inventor named Wald invented and directly improved the steam engine. Subsequently, under the influence of this new power source, mankind quickly began the first industrial revolution - to use the proper noun of this world, this is called "great innovation".

However, when the first industrial revolution had not yet caused enough socio-economic changes, the second huge discovery emerged—humans discovered minerals that allowed objects to jump directly into space.

What is this mineral in detail, how to achieve space jumps, how people ensure the correct direction and distance of space jumps... These problems have tormented Dusander couldn't sleep at night.

But he has not learned the relevant knowledge yet. The aristocratic families adopt the education model of tutors for their children. All the knowledge is spread through the oral and blackboard writing of the tutors - he cannot even satisfy his curiosity by reading the textbooks in advance.

In short, after discovering this mineral, humans completed the first successful manned space jump in twenty years, and then quickly discovered dozens of planets suitable for human habitation and survival.

The rapid expansion of human living space has become the best weapon to ease social contradictions.

Under the gentle economic and social conditions, the demand for technological progress is no longer sharp. Anyway, there is so much space and resources. The steam engine is not only not quickly replaced by the demand for miniaturization and quieter and more efficient, but has continued to develop with extremely vigorous vitality for nearly three hundred years.

The great technicians with sufficient professional knowledge have basically been hired as application-oriented talents by various colonial companies or nobles with high salaries. Humans have basically been in a state of minor repairs and repairs. Today, the steam engine has been developing on the road to miniaturization for a long time, but the progress is extremely slow.

The basic concept of external combustion engines has never been challenged.

The internal combustion engine, which should have appeared about a hundred years after the improvement of the steam engine, was two centuries late.

Now, it appears before Dusand.

"So, what fuel does this machine use?" Dusander closed his divergent thinking and focused on the amazing machine in front of him. The efficiency of the internal combustion engine is naturally higher than that of the external combustion engine, and it is more conducive to miniaturization than the steam engine. At the same time, the noise is smaller and the vibration when running is much smaller than that of the steam engine.

But the problem is that internal combustion engines do not have as good appetite as steam engines. Almost all fuels can be used as heat energy sources for steam engines, but internal combustion engines can only use several specific fuels.

Although humans have discovered oil today, this fossil fuel has been discovered on only six colonial stars. At the same time, the "oil" substances produced by different colonial stars are also very different. At least in Nuozar, the "oil" discovered by people is extremely viscous, almost the same as asphalt.

Such fuel is obviously impossible to serve as an ideal source of heat for internal combustion engines.

"We use gas." Polina's nervousness improved significantly when talking about professional knowledge. She whispered, "It is a toxic by-product produced during mining."

Although she didn't know why Lord Dusand, who was only ten years old, could recognize the internal combustion engine at a glance, and even less why he seemed to know this machine very well. But she explained, "The coal price under the control of the mining consortium is really too expensive. If the gas they don't need is used as fuel, the development prospects of this power equipment would be very good..."

Dusand shook his head and said with regret, "This machine has great potential... but unfortunately, you are in Newar now."

Polinamin didn't quite understand Dusand's meaning, and she persistently defended her invention, "I am very confident in my invention, and its potential is endless."

"It's not wrong to have endless potential, but if you want to get the ideas of all gentlemen at this dance... you're probably disappointed." Dusand frowned, "After coming to Newar, your machine has never been experimental yet?"

"Because there is no need, the time is too short, and I don't bring much gas..." Polina's voice sounded a little guilty, and then she quickly added, "I've tried it many times when I was in Orin, and it worked perfectly!"

"In Olin? No wonder." Dusander smiled very much in line with the image of a ten-year-old boy. "I can assure you that in Newar, this machine will not be able to continue to operate at all. Your invention will become a laughing stock of all nobles - its failed display will cause great damage to your reputation, and from then on, the entire empire will recognize you..."

He paused, then saw the name tag that Polina had engraved on the machine, and added, "...Ms. Polina, is a total liar and paranoid."

No matter how noble the little lord in front of him is, the equipment he invented with countless enthusiasm and energy has been degraded to this extent, no inventor can accept it.

Polina's lips turned white, and she was almost about to open her mouth to blow out the child who knew nothing but said wildly.

"But I can help you improve it," Dusand said with a smile. "Its future prospects are very bright, but first of all... you have to know why this work of art cannot function properly in Newar."

Before the other party raised questions, Dusand first revealed a small part of the answer, "This is Newar, the plateau planet with an average equivalent altitude of 2,400 Yoll. And Olin's average equivalent altitude is only twenty-seven Yolls. Such a machine can still operate normally in Olin, but this is Newar. Your work may not be able to support a successful cycle."
