Jiang Wangshan is the most useless good-for-nothing in Qingniu Village. He eats everything and never gets anything done. Then he finds a strange glowing piece of bread: one bite gives him a photographic memory; two bites let him recite anything backward. The price is that every time he uses it, he gains three jin, which he has to work himself to exhaustion to lose. From then on, the imperial examination hall becomes his stage. The Four Books and Five Classics? Memorized. Military strategy? Studied. Alchemy and formations? One look and they're mine. Everyone laughs at how fat he is, until he loses weight while earning top marks and solves a thousand-year-old mystery while running. What kind of genius? I eat a piece of bread and study harder than you do in ten years.
