I did some research and aparently solo leveling was an unpublished webnovel in 2014 while One Punch Man was a webcomic all the way back in 2009 so it did the workout first Just wanted to point this out

When I first read the story I thought that it was going to be an incredible story of a person raising armies to fight hoardes of monster and protect earth or something of the like however as the webnovel was coming to a close it began to be an awful story where the protagonist becomes to overpower and it then becomes stuipd the idea of upgrading this is a great idea for novels but the way the authors wrote the ending left a bitter taste in my mouth. The charaters in the story didn't seem to be fleshed out enought an example is the main protagonist all we know is that he is "special" having a mysterious background of being an orphan or what ever and that he went back in time. The novel it self was ended to quickly and made it become a story with a offputting ending if the novel kept going then it would have become something that many people would enjoy

Cool
