Taking Back The World With My Shadow System

This story is only posted to here (RoyalRoad) by me, the author. Anywhere else it has been posted is not authorized by me. It is and will remain free to read. 1) This story features a simple leveling system with hidden mysteries and components that will progress with the story.  2) The MC will be overpowered and will utilize a mix of shadow/assassin abilities with magic to overpower his enemies. The MC will be merciless but fair and will never kill simply because he is angry.  3) Romance will be prominent in this story and will play a large role in it. There also won't be much drama and/or breakups. There will be one female MC and she won't go away. If it wasn't already implied, that means no harem either.  Ryzen was just another broke college student, preparing to slave away at some corporate job for the rest of his life. That was until he and his entire university class were summoned to an entirely new world. Instead of joining an army to fight the demon lord or appearing in a nice forest, each of them were promptly enslaved and forced to live out the rest of their lives as living cattle. Fortunately for Ryzen, he was blessed with an ability to hide his inherent strength allowing him to slowly hunt and oppose the powerful vampires that were keeping him captive. Ryzen would ensure they didn't know what hit them.  Currently uploading every other day :)
