Reborn in the bitter winter of 1990, Lin Xudong, who had suffered a tragic death beneath an overpass in his previous life, is determined to rewrite his fate. Facing pressure from his mother and his younger brother's gambling debts, he resolutely separates from the family and leaves with nothing, taking his wife and daughter to live in a dilapidated earthen house. Starting from digging for dangshen roots and selling fabric, he uses his foresight and hard work to gradually establish a garment factory, venture into real estate, and eventually become the richest man. Yet what he treasures most has always been his wife's words, 'I believe in you,' and his daughter's innocent smile. This is a heartwarming story about protection, perseverance, and family—from a single roof beam, he builds a shelter that will never collapse.
