Something like RMJI, be sure to check out my reading list before recommending, peace. To clarify, I'm not looking for a genius protagonist, simply looking for the average dude, like the MC from RMJI(Tag says full title) nor am I looking for cheat stories.
Everyone Else is a Returnee I Reincarnated For Nothing Infinite Competitive Dungeon Society Seoul Station’s Necromancer Dungeon Defense Death March kara Hajimaru Isekai Kyusoukyoku (WN) In a Different World with a Smartphone I admit i dont really know what RMJI stands for, but anyway the MCs in the novels above are quite mediocre. (rather story ruining for me, but maybe you'll love it?)
Immortal Mortal but both stories stay true to their titles RMJI is not mediocre at all in my opinion hes just fine after some arcs and it only gets better Immortal Mortal has the true Immortal Mortal i do not like that the title truly stays with the story
really? mediocre? you know thats pretty much a bad way to say average/normal, and you pretty much only list novels with cheats
