My OP Minion System in the Apocalypse - Chapter 212 World Discovery

In Heaven’s Vault Continent, Colossal Dragons, Titans, Beast People, Fairies, Magical Beasts, and other races reign supreme!

But when she opened her eyes, she discovered, to her very horror, that she had returned twelve years into the past…

A mechanical engineer Poul Nielsen along with his best friend Jonathan Axelsen a civil engineer died after a truck crashed at the coffee shop where they were hanging out and got transmigrated in a late 19th-century parallel world, in the country of Avalonia. It was at the height of the second industrial revolution and to survive daily, they’ll have to work like others to earn pennies to get by the day. However, the two didn’t settle for less. They want to be the Edison, the Chrysler, the Rockefeller, the Carnegie, the Ford, and the Westinghouse of this new world.

This world doesn’t seem to have electricity? Then let’s start an electric power distribution company. Light is not enough, let’s build appliances and motors as well to make our business profitable.

This world doesn’t seem to have vehicles and ground transportation relies solely on horse-drawn carriages and trains. Let’s start an Automotive Manufacturing Company.

Huge infrastructure projects such as metro stations, skyscrapers, bridges, tunnels, and dams? Let’s start a Civil Engineering firm and build miracles in this world.

There is always money in guns, they say. Fine, let's invest in another venture, the arms manufacturing company.

And before we even know it, we will be the richest men in the world. However, the path won’t be easy as fierce competitions are up ahead. Robber barons who would do everything just to crush their competitors. Predator against predator, and government intervention.
