World Development System - Chapter 320: 251. How can this be possible.

Ruins stretched across the landscape in the apocalypse after the nuclear war.

Jin Yeong was just another office worker—forgettable, unremarkable, and stuck in a life that never went anywhere. He wasn’t strong. He wasn’t talented. In a world of ambition, he was just… there.Then, the sky cracked open.A voice echoed across the world, mocking humanity’s weakness. A system was given. A chance to survive.People awakened powerful abilities—fire, lightning, super strength. Jin got this:[Limitless Weapon Mastery]“Any weapon you wield is used at its maximum potential.”No fire. No magic. No enhancements. Just a simple skill?But soon he and the world will learn a simple truth:It’s not about what you wield. It’s about how you wield it.

Years later, Vincent meets with an infected survivor named Kevin, who helped him heal his heart. However, not all stories have a happy ending. Unfortunately, Kevin would pass away ten years later and leave a book with heroic tales as promised behind.

However, the book wasn’t as it seemed and after Vincent reads the book, it teleports him to the world the book depicts. A world of sword and magic with a horrible twist. Heroes are referred to as invaders, so people hate, persecute, and kill any otherworldy hero summoned to their world.

As an oddity to the world and possessing an oddity residing in his body, Vincent becomes the only person in the world to awaken two classes. A Hero and a Mutation class. The more retainers he acquires, the stronger he becomes through mutation.

This is the journey where Vincent starts from naive to brave, zero to a hero. From a single young adult to a harem king, from a nobody to an important person to many.

As Vincent tries to survive with people he can trust, he would receive many titles such as Harem King, God, Miracle Worker, Hero, Husband, Master, King, Monster, and many more.

Multiple questions will haunt Vincent’s thoughts while living in the new mystical and strange world.
