Yeah this is an instant drop for me, even among isekai this is super generic. Despite reincarnating multiple times, as a sage and hero, the MC has zero self-awareness or common sense. Like what others have already pointed out, this sucks. It's so generic I swear I've already read the first few...
I'll stay for the art, but so far the MC's comedic 'OP child can't comprehend his own strength' gimmick is really dragging this story through the dirt. People straight up tell him he's strong and he magically doesn't hear them.
