His life was filled with misery, but there was one ray of hope in his life- his girlfriend.That lasted until he found her cheating on him in the middle of his apartment with his best friend. Feeling betrayed, Liam sought to end it all by taking his life, and just as planned, he got hit by the truck in the middle of the busy street.It should have been Liam's end, but for some reason, he survived and woke up three days after in a hospital with no injuries and a whole new set of memories in his mind.And that is how he became the Immortal Warlock in the Modern World.He was oppressed once, and now, it is time for Liam to oppress everyone in the world.
