"The principle of hot air balloons is that the density of the air in the balloon becomes smaller when it is heated, and its mass is lighter than the cold air outside the balloon, so the balloon produces buoyancy and lifts off!
We don't necessarily need to use hot air balloons. If we use another kind of gas that is lighter than ordinary air, we can do the same thing.
I remember that when I was at Akkad Alchemy College, an alchemist extracted a gas that was lighter than air. Can we use this gas to make airships? "
The Mike Alchemy Institute specialized in the manufacture of cargo and manned hot air balloons. A long time ago, the Akkad Alchemy College had been conducting this experiment, but it had failed in the end. It wasn't that they hadn't succeeded.
The Mike Alchemy Institute, which was affiliated with Wisteria Alchemy College, had also started this alchemy research project. After Lars joined the Mike Alchemy Institute, he put forward a different and novel concept.
Later, it took several years for a new airship to be born. They experimented with different materials to make it, and the blueprints were changed one after another. The airbags expanded and burst again and again, and they racked their brains to change the shape and design of the airship.
In the end, they finally succeeded. The gigantic airship carried 20 people and goods and flew into the sky. Even though it could only fly at a very slow speed and could only carry a limited amount of weight, it was still very dangerous and had all sorts of problems.
The production of airships was also very low. Because of their slow speed, they weren't very practical, so they weren't widely used. They were expensive and complicated to use, so they didn't have commercial value. Only some nobles and the military tried to order them, but they also brought great wealth to the Mike Alchemy Institute.
At the same time, the reputation of the Mike Alchemy Institute quickly spread among the alchemy warlocks. Everyone found out that the person who had created such a project that alchemy warlocks could not complete turned out to be an ordinary person, an alchemist with the title of a fake alchemist!
Lars' story spread among alchemy warlocks and various alchemy colleges. The story of an ordinary person who had been struggling for his dreams was always full of appeal. Marina, the dean of Akkad Alchemy College, also heard Lars' story and chose to meet Lars Brown.
After a conversation with Lars Brown, Lars Brown talked about his ideas about the steam engine. He said that he was inspired by the use of wind and water power by alchemists, so he wanted to create a real power machine.
Ms. Marina affirmed Lars Brown's intelligence and ideas, and accepted Lars Brown, who was not an alchemist and had no talent in alchemy, as a student.
At the age of 40, Lars Brown finally fulfilled his childhood and student dream, becoming a student of the legendary adventurer and alchemist Ms. Marina. At the same time, he was reinstated as a student of Akkad Alchemy College.
In the Akkad Alchemy College, Lars Brown once again launched the research and development of the steam engine. With the support of alchemy warlocks, he finally launched the research and development of this project.
Although the steam engine was built, it was still very unpractical. After many generations of improvement and manufacturing, it was finally put into use.
In the early days, the steam engine was used in industrial production and industrial spinning, which further promoted the development of workshops. In the entire city of Te。, a variety of workshops using steam engines as power quickly began to appear.
When Lars Braun died at the age of seventy-four, he had yet to fulfill his promise of applying the steam engine to ships. However, the steam engine was brought to the world by Lars Braun, and the seeds of change had been planted.
When Lars Brown died, he was very calm. He gently held his grandson's hand and said, "As long as you have a dream, you can change your fate!"
After saying this, Lars Brown left. On his tombstone, just like his last wish, was engraved his nickname – Tomb of the Fake Alchemist Lars Brown.
Below the tombstone, there were also the words he had said before he left: "As long as you have a dream, you can change your fate!"
In the 215th year of the San Calendar, Lars Brown's grandson, Brown Jr., finally built the world's first steamboat. It was a wooden steamboat with huge wheels that were very conspicuous and had not even replaced the sails.
However, this was a huge change in the times. The fleets that had been sailing offshore once again began to explore the deep sea. In the 223rd year of the San Calendar, since the great adventurer Marina Bossa arrived in the Yala Elven Continent for the first time, human beings once again made contact with the Elven Continent.
The structure of the world changed again. Even though the connection between the continents had not been completely established, the world above the sea was still the world of monsters and demonic beasts, and the sea routes had not been completely established, it was a sign that the world was changing.
The era of the steam engine was far from beginning!
In Akkad Alchemy College, Marina, who was sitting in the dean's office, was still young and beautiful. She finally broke through to level four and became a level four alchemist. Her body was getting old, and her mind power was getting weaker and weaker.
After breaking through to the fourth level, she had a lifespan of a thousand years. As long as she didn't encounter any unexpected death or other problems, the serious problems of life and death were temporarily solved for her.
Marina was far luckier than her teacher Akkad, and she was also much luckier than most wizards. There was only one chance, and failure would lead to serious consequences such as death and mind power problems. Therefore, most level four wizards would rather not break through than try.
Marina was very interested in the steam engine made by her student. "It's a pity that Lars didn't have the talent to become an alchemist. Otherwise, with his wisdom, he would be a great alchemist warlock."
Marina used her own alchemy table, added a variety of metal materials, and created a relatively rough steam engine. The pressure of the first generation of steam engines was relatively low, and the valves could not be automated, so there were a lot of limitations in the use of it. Marina also tried to improve on it.
Akkad, the mechanical alchemy life, also tied Marina up as an assistant. At this time, Marina looked at Akkad and suddenly thought of something.
"What if I use metal cells to make a steam engine?"
"It has its own power. If I treat it like a heart or an organ, make a steam engine with metal cells, and let it have some of the characteristics of an alchemy life, what will happen?"
"It can self-repair, self-operate, self-evolve, and can be controlled at will according to the ideas of alchemists. If extraordinary power is integrated into it and refined into an alchemy tool, what kind of effect will such a metal-activated steam engine have?"
Marina felt as if she had opened a door to the world of steam. Although many ideas were still very vague, Marina felt that as long as she perfected it and created a real metal activated steam engine, a new era of steam would come.
