An accident leaves Lin Ziyu, a Xiucai from Qing County, with nothing but two dilapidated houses and a mountain of debt. While everyone assumes he will live in poverty, he sets his sights on the most unremarkable thing of all: soybeans.
Without a System or golden finger, and with no powerful connections to rely on, Lin Ziyu uses sheer determination and wisdom beyond his era to transform ordinary dried tofu into something extraordinary. His secret-recipe dried tofu smells delicious for miles. It not only revives the business of Liu Rumei, a beautiful widow whose small teahouse is on the verge of collapse, but also catches the eye of the wealthy Li family, who sign a contract worth a fortune!
But immense wealth attracts wolves. Jealous ruffians want to wreck his business, cunning tycoons covet his secret recipe, and some of the workers he hires are lazy and dishonest... From taking the imperial examinations and screening workers to establishing rules and fending off open and covert attacks, every step is fraught with danger.
Watch how an ordinary commoner stirs up a storm and commands the business world, turning the tides with a flick of his hand. Faced with threats and temptations from all sides, how will he protect the one source of warmth he has and the foundation that lets him stand on his own?
