Lu Yuan spends six years developing non-slip mining boots and is on the verge of securing a major mining contract. However, his biased family destroys his samples to pay for his cousin's engagement gifts and sells his core formula for a mere twenty yuan. Forced to leave home, he encounters a retired rubber craftsman and uses discarded rubber materials to improve his soles, developing specialized tread patterns for different terrains. When competitors maliciously copy his designs and flood the market with inferior shoes, Lu Yuan proves his products' superior grip and durability through a live demonstration. He reclaims his family's ancestral shoemaking molds, establishes a workplace safety footwear workshop, and stages a complete comeback through outstanding craftsmanship.
