Lu Yunzheng takes over the Beichen Soda Factory, which is on the verge of bankruptcy. Facing a veteran technician who holds the secret of the flavoring process and uses it to blackmail the entire factory, he abandons the workshop-style practice of relying on individual workers to adjust flavors and introduces standardized industrial production to stabilize soda quality. He subsequently faces a series of severe challenges, including distributors cutting off supplies, foreign beverage brands squeezing out local products, and overseas capital and technology imposing financial and technical blockades. Lu Yunzheng steadfastly upholds product quality standards, builds his own raw-material production lines, opens a transparent factory, establishes a franchise system, and develops indigenous technology to break through the restrictions. With a rigorous set of industrial standards, he secures a foothold for locally produced orange soda in the national market, writing a story of resurgence through perseverance and a commitment to the original ideals of domestic industry.
