Sorry, I'm Just a Cannon Fodder

"Okay, next, you only need to answer a very simple question on the spot, and you can enter the Pig's Knuckle Academy." The handsome and restrained examiner opposite me said calmly, his eyes constantly looking at the people waiting against the wall. Sure enough, the radiance radiating from my body made it impossible for this teacher to look directly at me! "Come on! Tell me what the question is! Let me answer it easily and give me full marks!" I shook my sleeves and looked around the audience provocatively. "Suppose for any smooth directed closed surface S, there is ∮∮xfydydz+yfxdzdx-zb+fx+ydxdy=0, where the function fx is continuous within -,+, and f1=aa, b are constants, find f2010." WTF? What is this? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
