Partner Xu Qiang steals the top-secret tidelow spots and fresh-keeping formula, driving Lin Xi to a dead end. She has no choice but to team up with retired Michelin chef Lu Cheng, setting up a stall at the dock to sell 500-yuan "tidelow blind boxes". Stonefish and goose barnacles explode across the city. Envious, Xu Qiang reports and tries to seize them, but is surpassed again and again. Lin Xi steadfastly upholds ecological tidelow, wins the gold award at the culinary culture festival, and turns the small stall into a city landmark. Past betrayal instead achieves a much broader world for her.
