I'd like to put this here for all those who will be interested in reading. This book is not the sort of novel where the main character goes around taking all the abilities in the world for himself. Nor would it be a book where only the main character has screen time and we only focus on what he's doing as he goes around saving damsels in distress. I want to write a novel where all the characters have their personalities and trials. The readers do not have to love only the MC since all the characters have something worth relating to, they can like any of the characters.

There will be powers that the MC cannot have (Ever) and people the MC cannot fight (For now). Things will happen outside of the MC's control and he might never even know about it. If things like these aren't to your liking, or if you want a book where you just watch the MC run around and spawn crazy skills mindlessly, then this book might not be for you. But if you can stay with me on this journey, I promise to write something you'll love.

[Pre-Author's Note: MC develops as time passes, it starts out slow but surely]“The Apocalypse isn't just fit for anyone... Without Strength, you're just a tool waiting to be exploited, So hurry the fuck up and get some strength already,”The world ended in an instant.One moment, Simon, a 20-year-old game designer, was sitting at his desk, immersed in code.The next, the sky cracked open and monsters poured into the streets.Werewolves with claws sharp enough to slice through steel.Undead skeletons that marched with deadly purpose and Zombies that infected humans with the power of their bite.The gods had unleashed an apocalypse, and humanity was no longer at the top of the food chain.Simon ran, he survived... and then he was granted a power.|Congratulations You have been binded to the Vampire Overlord System|He was something else.A vampire overlord.Yet the Apocalpyse had only just begun...

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?
