Sole Observer

In "The Only Observer", the universe is redefined as a probability ocean composed of "information wave functions", and humans become "observers" who can collapse reality through the "Eigenstate" game - a high-dimensional observation lens. When the "decoherence worm swarm" threatens the earth with vacuum decay, cleaner Qi Yuan relies on his "absolute observer" physique and [probability wave horizon] ability to embark on an epic redemption journey across the quantum scale. The story is divided into four grand stages: from micro-interference to macro-entanglement, to the ultimate showdown with causal weapons. Qi Yuan, the companion body eclipse (a group of "strange seeds" pursuing chaos) and the heroine's superposition state Van (Boltzmann's brain) jointly built a unique "quantum bond". When the universe faced a restart, Qi Yuan finally became the "only observer" and opened a new era for all civilizations by redefining physical constants.
