Lin Yuan uses his family's traditional starter dough to turn his bun shop into the most prosperous business at Tiefeng Factory. A greedy landlord grows jealous, hikes the rent to an exorbitant price, and seizes all the equipment. "You can have it all. I'm leaving." Lin Yuan walks away with nothing but his precious starter dough. The landlord thinks he has struck gold, but instead uses rotten meat from diseased lymph nodes and industrial chemical flavorings to make poisonous buns. In less than three days, a food safety scandal erupts! Thousands of furious blacksmiths smash the unscrupulous shop, leaving the landlord facing millions in debt and possible imprisonment. At his lowest point, Lin Yuan makes a commanding entrance with cash in hand and buys out the permanent property rights to South Street for a rock-bottom price. The real lifeblood of the business is something you will never be able to take away in your lifetime!
