Lei Juntian, a social beast living a completely useless life in the real world, was accidentally bound to the [Fate Decision System] in despair and was forced to travel through dimensional spaces that were on the verge of collapse. Every space is a trial of life and death: Sakura Academy that has been eroded by data, a steampunk-style mechanical wasteland, a strange mirror-copied city... And the only survival rule given to him by the system is to make "choices" at critical moments.
Choices determine fate, life and death. Should he sacrifice his teammates to save himself, or should he risk his life in a desperate attempt to survive? Should you trust the sudden appearance of allies, or face an unknown and powerful enemy alone? Lei Juntian grew up rapidly in each choice, transforming from a cowardly and escaping ordinary person into a decisive and ruthless "dimensional selector".
But he gradually discovered that behind the so-called system mission was actually a carefully planned screening conspiracy. The mastermind behind the codename "Ω-0" regards him as a spare for the "perfect container". The collapse of all dimensional spaces is just to extract his data and create the final descending body.
When the truth is revealed, Lei Juntian must make the final choice: become someone else's chess piece, or break the rules and become the chess player?
