All these series in my reading list are WNs/LNs that are masterpieces. I have personally read most of them and their quality can be guaranteed. Most of the series I recommend are fully translated/ have decent amount of chapters translated. The novel are ranked in no particular order; all these series are masterpieces of their own right, it is unfair to rank them by how good they are. 

*Take note that some of these completed series have dead links, you can search google for other sources to read them. Trust me its worth your time.
