Lin Ran, a brilliant Ph. D. candidate in computer science, vanishes after stumbling through a mysterious portal on New Year’s Eve 2019—only to awaken in 1960, trapped in a world where advanced technology barely exists.

With his encyclopedic knowledge of aerospace engineering, AI, and quantum computing, he becomes an unwitting architect of technological revolution, solving problems no one else can comprehend. As he navigates Cold War-era military labs, secret NASA projects, and paranoid government agencies, Lin realizes the portal wasn’t an accident—it was a deliberate breach from a future where Earth’s tech has been hijacked by an alien or interdimensional force. Now, every equation he solves, every circuit he designs, draws attention from shadowy factions who fear what he might unleash—or who might be watching him from beyond time.

With no way home and his mother’s life hanging in the balance, Lin must outthink enemies from both past and future before his genius becomes the weapon that destroys the world he’s trying to save.
