In the 22nd century, technology has become godlike, yet humanity faces a silent judgment. The constants of physics are quietly declining, and Earth's Gaia consciousness initiates an immune purge through "Law Erosion." Li Wei, the newly appointed guardian of civilization, faces an ultimate choice: follow the "Ascension faction" and upload consciousness to escape into virtual eternity; join the "Seeding faction" and journey across the stars to scatter the seeds of civilization; lead the "Dimensional Regression faction" in self-devolution, living humbly alongside their home planet; or face the universe-spanning "Zeroing Protocol" head-on, using the memories and emotions of an entire civilization as ink to compose a "Swan Song" that proves its worth to the merciless laws of the universe? This is an ultimate reckoning over survival, dignity, and meaning. Its answer will be carved into spacetime itself, echoing to the end of time.
