http://www.mangago.zone/read-manga/ranker_who_lives_a_second_time/ -most similar one I could think of
http://www.mangago.zone/read-manga/gosu/ -this is only similar in being a webtoon and action, but if you're bored, try giving it a try. It's about an op dumpling delivery boy and his teacher's dying wish. He's already crazy strong, but encounters just as many strong people
Plz recommends any manga that similar to solo leveling.. I'm bored af ╥﹏╥
