traveling the multiverses with a system

this is a novel/fanfic about my OC dying and getting reincarnated in different fictional world's such as dragon ball, one punch man, one piece, hunter x hunter and some other worlds I fancy. he gets stronger over time and fights some OC enemies. no harem, my character only gets one girl. I'll upload when I feel like it but I'm uploading everyday for the time being I don't own any of the characters only my oc's.
