"Don't worry, I know what you've taught me, Master. If anything confuses me, I'll consult you again. You've had a long day too, so you should rest early. Oh, have you had dinner yet? Otherwise, shall I make something for you?"
"What's this, you're even offering to cook? If I had brought you here, wouldn't I have really hit the jackpot? To think, I'd have gained an assistant too?"
"Master, what are you talking about? It's just that in the past, when I was with Grandpa, sometimes he'd get so absorbed in his research that he'd forget the time. So, if I was free, I'd cook some meals for him—simple dishes, those are no problem; complicated ones, I definitely wouldn't manage."
"All right, no need for that, I'll do it. You're here as an apprentice, and don't worry, I'll pay you a regular salary. Moreover, I won't make you work for nothing."
