Guardian:
看来赵处长是有眉目了，要不然哪有时间到我们学校来参观, it seems you have something in mind, Chief Zhao, otherwise how would you have the time to come and observe our school?
我已经明确地告诉过你不要过多地接近圣器，要不然黑能量它会, I have already clearly told you not to approach the Hallows too closely, otherwise the dark energy will--
赵处长，我跟你说过，不要过多地使用圣器, Chief Zhao, I have told you not to use the Hallows too much (Shen Wei making the same point in two different personas with two different grammar points)

Me:
咱们最好不要多聊，要不然我会错过火车。
