"The principle of a hot air balloon is that the air in the balloon becomes smaller after being heated, and the mass is lighter than the cold air of the same volume outside the balloon, so the balloon generates buoyancy and takes off!"

"We don't necessarily need to use hot air balloons. If we use another gas, a gas that is lighter than ordinary air, we can do this."

"I remember when I was in the Akkad Alchemist, an alchemist extracted gases that were lighter than air. Can we use this gas to create airships?"

The McAlchemy Institute focuses on the manufacturing of objects and manned hot air balloons. A long time ago, the Alchemy Institute of Akkad Alchemy Institute was conducting this experiment, but it failed in the end, not without success.

The Mac Alchemy Institute is affiliated with the Wisteria Flower Alchemy Academy and also started this alchemy research project. After joining the Mac Alchemy Institute, Lars proposed a different novel concept.

Then, after several years, a new airship was born, and various different materials were experimented for manufacturing. The drawings were modified one after another, and the airbags expanded and burst again and again, racking their brains to transform the shape and design of the airship.

Finally, it was finally successful. The huge airship carried twenty people and cargo and flew into the sky. Although it could only fly in the sky at a very slow speed, the weight it carried was limited, and it could only carry out some close-range navigation, which was also very dangerous and had various problems.

The production of airships is also very low because they are very slow and do not have much practicality. They are not expanded. The price is high, and they are very complicated to use and have commercial value. Only some nobles and military try to order, but they also bring huge wealth to the McAlchemy Institute.

At the same time, the reputation of the McAlchemy Institute quickly spread among the alchemists. All the people discovered that the one who created such a project that even an alchemist could not complete was an ordinary person, an alchemist with the title of fake alchemist.

The story of Lars spreads in alchemists and various alchemy academies. A story that ordinary people have been struggling for their dreams is always full of infectiousness. Marina, the dean of the Akkad Alchemist Academy, also heard Lars' story and chose to meet Lars Brown.

After talking to Lars Brown, Lars Brown talked about his thoughts about the steam engine, saying that he was inspired by the alchemist's use of wind and water, and wanted to create a real powered machinery.

Ms. Marina affirmed Lars Brown's ingenuity and ideas, and would accept Lars Brown, who was not an alchemist and did not have the talent of an alchemist, as a student.

At the age of forty, Lars Brown finally fulfilled her dream of childhood and student days, becoming a student of the legendary adventurer and alchemist Ms. Marina, and at the same time recovered her academic status at the Akkad Alchemy Academy.

Within the Akkad Alchemy Academy, Lars Brown once again started the research and development of the steam engine and led the project. With the support of the alchemist, he finally started the research and development of the project.

With the initial failures, although the steam engine was manufactured, its practicality was still very poor. After generations of improvement and manufacturing, it finally came into use.

Early steam engines were used above industry, using industrial production and industrial spinning, which further promoted the progress of workshops. Various workshops using steam engines as power began to appear throughout the city of Tephes.

And Lars Brown, until he died at the age of 74, had not fulfilled his promise to use the steam engine on the ship. However, the steam engine was brought to the world by Lars Brown, and the seeds of change had been planted.

When Lars Brown died, he was very calm and gently grabbed his grandson Brown's hand: "As long as you have a dream, you can change your destiny!"

After saying this, Lars Brown left, and his nickname, the Tomb of Lars Brown, was engraved on his tombstone, as his last wish.

Below the tombstone, there is also his descendants engraved on it. The words he said when he left at the end can change his destiny with a dream!

In the 215th year of the Santa Calendar, Brown's grandson, Little Brown, finally built the world's first steamboat, a wooden steamboat, with huge wheels that were very conspicuous on the ship and had not even replaced the sails.

But this is a huge reform of the times. The fleet that had been sailing near the sea once again launched an exploration of the deep sea and the ocean. In the 223rd year of the Holy Calendar, the arrogant adventurer Marina Bosai arrived at the Yara Elf Continent for the first time, and humans once again contacted the Elf Continent.

The pattern of the world has changed again. Although the connection between the continent has not been completely opened, there is still a world of monsters and monsters above the sea surface, and the route has not been completely established, it is a sign of changes in the world.

And the era of steam engines is far from beginning-

At Akkad Alchemy Academy, Marina, who is in the dean's office, is still young and beautiful. She finally got stuck in the limit of her body aging and her mental activity is declining. She broke through the fourth level and became a fourth level alchemist.

After breaking through the level 4, they have a lifespan of one thousand years. As long as they do not encounter unexpected deaths or other problems, the originally serious lifespan problem will be solved for them.

In order to advance to this level, Marina is much luckier than her teacher Akkad, and is also much luckier than most wizards. She has only one chance. Failure will lead to serious consequences of death and mental problems, making most level 4 wizards rather than try easily.

Marina was very interested in the steam engines made by her students: "It's a pity that Lars did not have the talent to become an alchemist, otherwise with his wisdom, he would be a great alchemist."

Marina used her alchemy platform to add various metal materials to create a relatively rough steam engine. The first generation of steam engines had a low pressure and the valve could not be automated, so there were many restrictions on application, and Marina also tried to improve it.

As for the mechanical alchemy life beside him, Akkadmund also tied Marina to serve as an assistant. At this time, Marina looked at Archmond and suddenly thought of something.

"What if you use metal cells to make a steam opportunity?"

"It has power in itself. What if it was treated like a heart or an organ, and a steam engine of metal cells was created to have some of the characteristics of alchemy life?"

"It can repair itself, operate itself, and evolve itself like life, and can control it at will according to the alchemist's ideas. If it is then integrated into it and refine it into an alchemy prop, what role will such a metal-activated steam engine play?"
