I'm reading the manga of Solo Leveling (chap.75 today) and wish to read the novel, does anyone can help where approximately is the novel in this part of history?
But seeing as it's only around 90 chapters, you might be better off reading it from the beginning. The story is slightly different and there are more details. Plus some terms are translated differently.
You can read it on web novel if you can wait to read one chapter a day or you can pay to unlock the chapters
Boxnovel is also a site to read it. The main story is done. All that are left are the epilogues which are quite a lot. It's also free. I think it has finished around 250 chapters already
