Michelin three-star pastry chef Gu Wanzhou, known as the "King of Rolls", stayed up for three days and three nights to get the perfect recipe. Once she traveled through time, she became "Gu Daya" in the slums of the capital city, with a bare house, a leaky roof, and three younger siblings who were waiting to be fed. Gu Wanzhou's eyes darkened as she looked at the black-faced steamed bun in her hand that could knock out teeth. Good news: People are still alive. Bad news: Life is worse than death, there is no way to live this life!
