Extra And MC - Chapter 210 - 206 - A Journey’s End

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

PS. Cover not mine, I just found it on google.

The world ended, seven days of earthquakes, volcanic eruption and then came the meteor storm, bringing something worse—mutation.Now, survivors are group into Shifters, mutated humans and normals.Ava Zhang was supposed to be a Normal. Useless. Disposable.Thrown into a military-controlled bunker, she is sorted into Level Three—the bottom rank, where the weak are left to rot. Starving, overworked, and surrounded by desperate scavengers, she realizes that in this world, strength decides survival.But Ava isn’t as powerless her hidden System activates. The Blueprint System—an ability that lets her design and invent anything, from weapons to high-tech defenses.

This year, Ji Jingqiu is 16 years old.To survive, he envisions the Fire House Buddha Prison, plants a bodhi treasure tree, and embarks on the path of martial arts.Many years later,A brilliant light arises, illuminating endless darkness.A towering ancient tree, with emerald green leaves and a canopy like a pavilion, rises with glass-like clarity into the sky, supporting a divine realm of pure land, spanning countless ages, illuminating the three realms and ten directions.On this day,All martial artists under heaven look up to it, like mayflies seeing the blue sky.......“Within there is a bodhi tree, which I planted when I set foot in martial arts, and now it has grown to provide a canopy.”“I see everything in the world, and nothing is like me.”“That year, I scoured history books, this history without era, I looked horizontally and vertically, and saw those characters – ‘The world’s storms come from us.’”...— Excerpt from the autobiography of Ji Jingqiu, the proud sun of the martial arts world of today.

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.
