A teenager finds himself mysteriously transported to a new world without understanding why or how. However, upon glimpsing a colossal tower outside his window and discovering that this realm resembles a game with dungeons, monsters, and skills, he resolves to conquer the tower known as 'Amartia.' His goal is to become the most powerful entity in this world while unraveling its secrets along the way. This is my first novel, and English isn't my primary, secondary, or even tertiary language. Nevertheless, I've made an effort to share my story and have received assistance in editing from some of my friends.
