How is 天论问宪 translated in English?
I have a complex feeling about Chinese trashy-novel "fever" in the West...
OK, time for the answer.
Translating literature is far beyond correctness. I'm not an expert, so I'd just bring you some suggestions.
For the title:
Thousand Miles To Become A God
Although a thousand is ten hundreds, the meaning of this title is not away from the original one.
For name of the book:
I don't know if the book appears more than once in this novel, but if it doesn't, it will still be fine even if we just name it by our instinct. By my observation, most authors of this kind of novels don't really care about proper names.
On Heavenly Principles
宪 has the meaning of "principle" as in 宪法 (constitution).
