A bloody calamity

The fortune teller did not know whether to laugh or cry. "I'm a fortune-teller. If you ask me to interpret dreams, calculate your chances of marriage or future prospects, I can do that for you. But why would you ask me to solve a math problem? That's science, while I'm a practitioner of magic. The two don't mix."

Ren Xiaosu remained silent for a moment before saying, "You said you can interpret dreams, right?"

"That's right." The fortune teller nodded enthusiastically. "I can interpret all kinds of dreams."

Ren Xiaosu said, "Then listen carefully. I had a dream about a question related to quadratic function f(x)…"

The fortune teller was dumbfounded. 'What fucking dream is that? Can't a guy help others read their fortunes even if he does not know how to solve quadratic functions! What the hell!'

Ren Xiaosu sneered. "You can't interpret that, right? So you're really a fraud."
