Infinite Devouring Upgrade System

This article tells the story of a killer who travels to the Warrior Continent and has a mysterious system. Let's see how he dominates the Warrior Continent. It's a novice novel. It's my first time writing this type of story. The story may be a bit slow. If you don't like it, don't criticize it. Please forgive me. If you like this type of story, you can leave a comment in the comment area and you will decide the story. This novel and its characters are purely fictitious.
