Transported to the 1960s through a fatal gas explosion, Bai Xue awakens as Bai Ruxue with an extraordinary advantage—a pocket-dimension supermarket brimming with provisions. Her inventory spans rice, noodles, grains, oils, fresh vegetables, fruits, snacks, and clothing, offering unlimited access to life's essentials. Armed with her miraculous storehouse, Bai Ruxue strategically exchanges her goods to acquire a home, automobile, prestigious employment, and precious metals. She proclaims with confidence, "Nothing in this world lies beyond my reach with this supermarket." Fortune shifts when Zhang, a mysterious gentleman, seeks her out with gratitude burning in his eyes. "How can I repay such a debt for saving my life?" His question evolves into a lifetime commitment, his devotion entirely devoted to her.
