Can anyone help me find this novel? It goes like this. 1. Mc is a hero in his world with 99 levels then he goes nirvana where there are a lot of heroes from other worlds. 2. He discovered that there are levels beyond his reaching up to 100-300 for 1st floor then 301-500 second and so on. He realized that he's newbie in that place so he needs to get stronger to not be bullied by other guys (which happened days after his ascension) 3. He killed several of his enemies on the first floor that makes his enemy of different guild and/organization. That's all I could remember. I read it several months back and I want to read it again~
