I don't get it

Every time I ever ask for some good reincarnation/funny mc stuff almost everyone recs this one https://www.mangago.me/read-manga/the_world_s_best_engineer/ but never in like the 3 or 4 times I've tried to read it have I ever found even remotely entertaining, it's so boring and unfunny, like gen why do people like it? Someone explain it to me
