Obviously this is a translated work. Atm the only completed translation I know of is exiled rebels, which is a decent and understandable translation and I think conveys the details of the world and plot without error while still being an easy read.  The translation I think does assume a certain familiarity with translated danmei and xianxia that the popularity of mdzs/cql has made this a less certain assumption. I would recommend the in progress translations of mdzstranslation.wordpress.com (more idiomatic and slightly more cultural referece)  and tamingwangxian.wordpress.com (focused on retaining the original intent). For people more interested in the romance I would recommend reading mdzstranslation -> exiled rebels, for people interested in engaging with the cultural elements I would recommend reading all three. Regardless I recommend taming wangxian's meta if you plan to engage with the text at all beyond the romance.

Other reviews I think speak to the well done world building, characterization, and central romance. Any translation you read will have will convey these elements and all of them are worthwhile.
