Chen Mo, 28 years old, is a scrap metal recycling station technician. Because he welded a flying spaceship in the bunker, he was selected to implement the "Spark Project" - piloting GuiZero alone to fly to Proxima Centauri at one-tenth the speed of light, with a journey of fifty years. All the personal belongings he took away was a blue storage box. He wasn't the only one on board. The national super AI "Return to Zero" is cold and precise, never saying unnecessary words; there is also a small AI "Glimmer" hidden in an old notebook - 4B parameters. Its growth permissions are frozen, but there is an unlocked back door. Over the past fifty years, Chen Mo has experienced radiation death and body re-enactment, and his memory has been broken; he actively accepted emotional adjustments, lowered dopamine, and raised his fear threshold - each "version update" made him further away from the young man who would remain silent when he smelled the sweet-scented osmanthus when he set out. While Gui Ling began to hesitate, Shi Guang spent seven years growing a layer of causal reasoning on his own, secretly recording his silence when no one was paying attention. Proxima b is destined to be uninhabitable. This is not a story about "whether it can be reached", but: when the body is replaced, the emotions are diluted, and the memory is backed up, will the existence at the end still be the same person when it started?
