"Haha! I told you, this guy would definitely get angry. But it's okay, I'll tell you how to keep your thing as lively as possible."
"First of all, you need to exercise some restraint yourself, don't always think about those things. Otherwise, forget about reaching forty, you might have trouble even in your thirties."
"Secondly, don't take those stimulating tiger and wolf medicines anymore. They are really bad for your body."
"By then, it might not just be a matter of not being able to perform in that aspect; you might not even be able to keep your life."
"If you can do these two things first, I'll tell you the rest. Otherwise, even a god won't be able to save you."
Just as Yang Yan finished speaking, the class bell rang.
Of course, he wouldn't waste everyone's time, nor did he bother with Master Zhou, who was in a petrified state. He simply said,
"Class dismissed! If you have any questions about the human body, you can come directly to the lab to find me."
