MTL - The Return of Cambrian Period - Chapter 280 New world

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?

In every story, there exists the hero and the villain, the protagonist and the antagonist.And like every story, the hero always wins, and always gets the girl.But what happens now that I died and became a villain in the last book I read? Not even a proper villain, but one that the protagonist kills in the early chapters.I don't want to die again, and I don't want that simp of a protagonist to walk all over me. Maybe I should just become a better villain.I've always admired the smart badass villains that took on the protagonist. Maybe I can be one of them, maybe I can win—the first villain to win against the hero.I'll rewrite this story into one where I become the greatest villain. Call me sick or evil, but it's my time to shine.
