MTL - Supreme Demon - Chapter 3475 Go to war!

Okay, so let me get this straight. I wake up and BAM, I'm inside the body of Valerian Thorne—a third-rate villain. I mean, come on? Out of all the characters I might have been reincarnated as, it had to be him? This man was literally a stepping stone for the actual hero. So why him? Why not someone with a little more. potential?Now that I have a system that can unleash Valerian's hidden potential, who knows? Perhaps this third-rate villain will get a second chance, alter his destiny, and prove the world what he is truly capable of. And if I happen to get to keep the gorgeous fiancée in the process. well, I'm not complaining.

He became a teacher at the best magic academy in the empire.

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?
