Introduction to the novel
In the year 2077, when the climate is collapsing, humans use quantum memory implantation technology to send "reconstructors" into history, trying to correct key nodes to delay the end. Chief reconstructor Lin Shen possesses a rare "dual timeline memory", but while performing a mission to prevent the nuclear explosion in Hiroshima, he accidentally triggered a rift in time and space, and discovered the cruel truth concealed by the organization - the end of the world is irreversible, and all actions are only to select "time immune people" to continue the fire of civilization.
At the same time, the mysterious villain "Raven" mastered reverse time technology and created a parallel time and space prison through time loops, trapping Lin Shen during the 1918 influenza pandemic. When Lin Shen breaks through the predicament with the help of his ally Su Li, he discovers that Raven's true identity is actually his split future self. In the ultimate confrontation in the doomsday bunker, Lin Shen must make a decision: Should he launch the "Return to Zero Project" to erase human civilization from history?
The story uses the image of "butterfly specimens" throughout, exploring the ethical propositions of memory, sacrifice and the survival of civilization. Under the framework of time paradox and quantum physics, it unfolds a century-long trial of self-salvation and civilization.
