Looking back at this post I feel like I didn't articulate my thoughts well - what I really wanted to do is not to comment on the quality of MDZS translation (because I haven't read it except for fragments), but to explain that localisation in translation isn't always what readers think it is.
Let's take as an example one line spoken by a dragon prince from a story set in fantasy ancient China:
translation version 1: Those ignorant humans sure know how to tell tall tales.
translation version 2: Those ignorant humans sure know how to bullshit.
Now which line do you think is more localised? Version 2 might sound tonally jarring given the setting, and it might seem more localised because it uses modern slang, but it's actually a more literal translation of the original sentence 這些無知的人類真會放狗屁, and this is because, as I explained in that other post, Chinese internet fiction frequently mixes contemporary slang with archaic language, which isn't something readers of English fiction are used to. So internet slang in historical/fantasy danmei doesn't always equal more localisation; on the contrary, an English translation of historical/fantasy danmei that reads tonally very consistent and which always uses language appropriate to the historical setting might actually be the result of localisation.
ok I'm done overexplaining
