A folding fan made of Xiangfei bamboo, holding the soul of a man who had refused to fade for five hundred years.
Ma Siwen, a Ming-dynasty genius of riddle-solving, died unjustly after a riddle contest before the emperor. His soul dwelled in the fan for centuries, until Liu Yiming heard his voice.
Liu Yiming, a descendant of Liu Yong, hated studying the classics and had no interest in lantern riddles.
By chance, during a riddle contest, Liu Yiming drew on the power of Ma Siwen's lingering soul to defeat Wu Jialiang, who came from a family renowned for its expertise in riddles and whose knowledge outshone all his peers. Their first battle bred resentment, and forged an unbreakable rivalry. From then on, on the riddle stages of the Ning-Su region, the two boys pursued each other step by step, each displaying dazzling ingenuity, testing themselves against one another through countless riddle contests, and growing ever more capable. More and more young people were drawn into this contest of words: a group of boys supporting one another as they pursued their own peaks.
They thought they were solving riddles. In truth, they were helping a man from five hundred years ago finish the road he had never completed.
