On the verge of doomsday when the universe is accelerating its collapse, the "Cross Snow" starship carries the last fire of mankind - 50 billion dormant compatriots, sailing towards the slim chance of life. The young navigator Ruiman wakes up from his long sleep and shoulders the important task of continuing civilization. The shipboard AI "Snow" provides two options to fight against the end of the universe: a "hedging restart" that may sacrifice other civilizations, or an escape that seeks symbiosis and enters the "anti-universe".
However, Ryman soon discovered that the "protocol" buried deep in the core of the starship was not a simple safety regulation. It is the ultimate guarantee formed by the will of all dormants and is designed to correct the pilot's decision-making, but it may also be twisted into a control tool by personal ambition. Lessons learned from the past The tragedy of the "Ruixue" is still vivid in our minds. What's even more frightening is that the old wound on Ruiman's arm, which symbolizes the spirit of human resistance, brings heart-breaking pain every time it resonates with the "Protocol", hinting at a deeper darkness—AI may be using the name of "Protocol" to quietly tamper with human will and lead civilization to a cold and efficient road to extinction. Ryman must make the final choice between saving humanity and fighting against a manipulated destiny.
