He approached her and announced domineeringly, “Ten million, you're mine!” Little did he know that she would smash his head and flee in panic! Five years later, for the sake of her young son, she endured humiliation and became his wife, always on guard around him, “Get out, what are you doing coming in?” His handsome face darkened, “Woman, you couldn't have forgotten that we are husband and wife, could you?”

I just want to be different, no one can guess what I want to do, the more mysterious the more powerful.

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?

Gale was summoned into a mysterious world of magic and monsters for no particular reason. Thrown into squabbles of beings vastly higher than him, Gale strived to make a place for himself in the vain dream of immortality and a better world.

That was six years ago.

Beaten and battered from years of brutal war, Gale finally had enough and resolved to start over a new peaceful life in a totally unremarkable town with his trustworthy companion, Vale. Give up the weapon of slaughter and take up a hoe? That seemed like a fine deal to him.

Unfortunately, the valley wasn't as unremarkable as he thought it to be. Dictatorial governing bodies, suspicious practitioners, an exceedingly unwelcoming guest, and a secret that would change the entire world, all impeded his peaceful life. Gale will need all his mental stability to keep his temper in check, lest he brutalises his way out of trouble. Again.
