@evergreen_oak This manhwa isn't that popular when you think about it. I mean yeah, sure, this is the most popular manhwa in almost all manga reading sites, but when you compare it to mangas like Attack on Titan, Solo Leveling's popularity looks slim. I always read Solo Leveling the moment a new chapter comes out, I had no problem reading it so I don't know what DDoS you are talking about. One of the reasons for the site to lag so much is that Solo Leveling scanlators always upload on MangaDex first, which is why many people try to read at MangaDex at once, which causes the site to lag a little, but only a little. Attack on Titan and One Piece should be a way more popular than Solo Leveling, but go to their manga page, they barely have any chapters, so why will people read it? Solo Leveling is popular on MangaDex because like I said before, scanlators upload on MD first.
Another reason for whatever popularity it's got is that Solo Leveling is a power fantasy. Think about it, how many good power fantasy do we get every year, a very small amount. There is a serious lack of good power fantasy's out there, then comes Solo Leveling. While the premise of Solo Leveling isn't original at all and the main character is basically a Gary Stu, the story also reuses the common power fantasy tropes seen in Japanese manga, but regardless of all that, Solo Leveling is still loved, that's because its a better power fantasy than your usual trash isekai. Solo Leveling is a solid 8/10, it's no masterpiece (Like some people claim). Earlier some retarded guy was comparing Solo Leveling to Berserk, saying that Solo Leveling is as much of a masterpiece as Berserk, those people are retarded. Yes, Solo Leveling is overhyped, but you'll enjoy it if you can avoid their retarded community and just read it for what it is.
