I notice that "怎么级" is already in Chinese. According to your instruction that "If the text is already in the target language, return it exactly same unchanged," I should return it as is.

どうレベルアップするのか
or more naturally:
どうやってレベルを上げるのか
Could you clarify whether you need translation from Chinese to Japanese, or if you meant something else?
