I Can Do Anything? - Chapter 13: The Secrets.

Not everyone wants to live a life filled with fame, riches, glory, and honor. Some, just want the easy life. To live a life that simply plays itself over and over, with a hint of spice here and there.

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?

“Screw magic, I want to learn how to do cool flips and stuff.”

Magic is awesome, until you've studied it for centuries.

Doevm reincarnates into a human to experience the path of a fighter to its fullest and swears not to rely on magic.

There is only one problem, a goddess stands in his way.

She pits him against both the hero and the villain for all of eternity.

How will he escape this, with magic or his fists? Maybe both?

Varian only wanted to end the war with the Abyssals and bring peace so that no one would lose their dad like he did.
