After transmigrating into Lin Mo, a blind live-in son-in-law despised by everyone in Qingliu Village, he is mocked for treating 'stinking mud bugs' as treasures and is forced to contend with bullies demanding rent and powerful elites conspiring to suppress him. Using his modern culinary skills and extraordinary perception, he transforms the neglected crawfish into an unparalleled delicacy that takes the capital by storm. With sophisticated business strategies that overturn the established social hierarchy, he breaks through class barriers. When danger strikes, ordinary people from the lowest rungs of society risk their lives to help him. After achieving success, he builds academies and charitable halls to give back to his neighbors. He also finds mutual love with Su Wan'er, who throws an embroidered ball when driven to desperation. In the end, he defeats the forces of evil and transforms from a hidden dragon in the mire into a legend who reshapes the capital's culinary world.
