System's Origin

Our SI gets fished out from River of Reincarnation by Supreme Being Merlin and given some boons for his journey. ______ It's another story from me. Which means I am going to re-heat the previous plots I used and I am going to add some pepper on it before serving. This thing has a useless system, multiverse, harems, god awful romance to the point people will pay me to stop writing and no action scenes what so ever. So just warning beforehand. Planned worlds: Assassin's Creed: Too short. Crysis. The Prototype. Cultivation Chat Group: Just going to get Karmic Virtue High School of the Dead. Witcher. My Hero Academia. RWBY DxD Naruto Fate Stay Night. I am planning to add more stuff later...
