✉️ Brother Chen, what does the third sentence mean?

Brother Chen, what does the third sentence mean? I hope you can enlighten me, and I will reward you generously after the test. Brother Liang, with your exceptional talent, why would you need my guidance? The monthly test is to measure one's ability, so please think deeply. If you can't find a clue, why not spend less time in frivolous places before the test and read more of the sages' books? Hmph, Chen. Just you wait!
