S2·E93 Operation Great Wall of China Invader

Lupin, Jigen, and Goemon steal the jade mah-jongg set which belonged to Emperor Shi, from the Peking Old Palace Museum. Even though he's kept his promise to get them for her, Fujiko won't marry him because he lacks intellect and refinement?! In that case, Lupin drinks the Confucian Analects, steeped in the Elixir of Learning, an ancient Chinese potion which enables one to absorb instantly the knowledge contained in any book which has been dissolved in the fluid. However, drinking the Analects transforms Lupin into a holy man, one who hates money and women. It's the conspiracy of Chang, a scientist turned gangster, who wants the mah-jongg tiles.
