tsk tsk tsk.. i believe the 'correct', 'proper' choice of phrase here should be "it must be understood that..." . it is IET's novel were talking about here, right?
It's an easy read. You should just read it in English and look for the words you don't understand on Google. C'est la misère les 50 premiers chapitres mais après ça passe tout seul
I think it's worth it. It's perfect as one of the first novel to read as an introduction to Chinese novels~
