Youngest Son of the Black-Hearted #1

Am I the villain in a different coat of paint or just the bane of a corrupted empire? I wonder...

Around age twenty-seven, they finally caught me off guard. As the youngest son of seven, children of the most powerful duke on the continent and archmage at that, the world expected us to fight over the throne.
I tried to keep my distance. Rescind my role. Go about my merry way as people called me the trash of the Thunder family. After all, my magic wouldn’t work for some unknown reason.
Well, it turned out distance wasn’t an option for me.
As the arrows and spears sent me to my death, I couldn’t help but wish to do it all again.
Someone or something answered my dying thought…
It can turn the clock only once.
I found myself back nearly a decade to where it all happened. Only something was different. I could feel the building blocks of magic or mana, aura, and even the flame of Ki.
I also knew who ordered the assassination.
Very well, Third Brother. You want to play games with me? I’ll make sure to destroy everything you’re building, before crushing your throat.

I’ll go beyond just claiming the throne of our ducal province…
