Lin Yu was trapped in a time loop on June 1, 2026, for a full thousand years, accidentally breaking free from the reincarnation to usher in June 2. He saved An Rou and assisted An Pharmaceutical in countering its commercial rival Chu Tianxing. Amid successive crises and games, he uncovered the secret of the Origin System, learning that he is an experimental subject deployed by the Origin. While protecting the An family and those around him, he pursued the truth behind the scenes, went through numerous dangers, penetrated the Origin control center to shut down the system, and broke free from the shackles of his experimental fate. With the storm settled, he let go of the past thousand years of reincarnation and embraced an ordinary, stable real life.
