Yun Heng was born in the Yun family's old house where day and night intersect. Every brick has an indescribable thousand-year echo. One night, he accidentally picked up a "Word of Time Stone" under the family altar, and was instantly involved in the rift between ancient and modern times - his shadow was reciting poetry in the Song Dynasty, making wine in the Ming Dynasty, and even dancing with artificial intelligence in a future century. The family's secret is a self-search across time - each generation of Yun's descendants must fulfill an unfulfilled wish in order for the family to continue to the next era. Yunheng kept talking to his ancestors and descendants in the chaotic time and space, but found that all the clues pointed to a shocking fate: the survival of the family turned out to be a rebellion against time itself. The core conflict is, can he break the "cycle of regret", loosen the web of time, and allow his family to truly be free? With a kaleidoscope-like narrative, surreal time and space jumps, and strange family bonds, the novel leads readers to explore: Between the torrent of time and family bonds, what is the true self?
