I am thinking of reading tmw so which translation is better and fun to read (including translator notes and stuff )
same translator. originally, cktalon translated it on gravity tales. then there was the gravity tales buyout by qidian which made cktalon move to wuxiaworld. he did this for a couple hundred chapters. later, qidian started poaching translators with a huge pay if they translate for them and move the novel to their site. cktalon was offered like 200 per chapter plus patreon at the time so he moved ships. that is the reason there are a couple hundred chapters on wuxiaworld. qidian has the whole amount though as cktalon is and has been the current translator. so to answer you question, you can only read the whole novel on Webnovel (what qidian goes by now) through legit means. if you want bits and pieces, then wuxiaworld. I think cktalon removed the chapters from GT though.
the translator from WuxiaWorld is the same as the one on Qidian. he was translating on WW but decided to move to Qi after a while so the quality is the exact same
I dropped it while it was still being translated on GT before it came out that QI owns GT I was a real GT fanboy at the beginning for a few weeks *melancholic sigh*
I just checked, it doesn't seem to be offered on WW anymore so if you're going to read it you're going to hit a paywall.
