Venomous-tongued gourmet food reviewer Half-Spoon Lu Wen, because of a three-line review condemning the century-old restaurant Judechun's signature Eight-Treasure Gourd Duck, is targeted by a nationwide crusade. Signing up for the food variety show "Cooking Stove", he becomes the mysterious sixth guest. On the show, partner Qi Yue sees through his identity via handwriting, and publicly sets a three-day retrial wager. His background is subsequently exposed: he is the grandson of the legendary national master God's Tongue Lu Yunfeng. On the retrial day, He Guodong publicly smashes a set up poisonous water, using clear water for an upright showdown; Lu Wen tastes it and pronounces it peerless under heaven, publicly uncovers the red plaque, and the century-old signboard is recast.
