History and Memory in Quantum Time and Space

On October 17, 2025, construction engineer Wang Dayou is injured in an accident at a construction site in Shencheng, dies, and transmigrates to the summer of 1962. While protecting a granary and working on a water conservancy construction site, veteran Wang Dayou discovers fragments of a childless elderly resident’s memories sealed inside the concrete. When an award certificate from 1958 begins to reveal quantum equations, he realizes that the work he is involved in is more than a defense project: concrete mixed with cremated remains is building a bridge between past and future in the folds of quantum spacetime.
