The blood moon volleyed in the sky, reality collapsed, and human beings were forced into the game "End Times", where life and death were controlled by cold rules. Lin Mo, an ordinary programmer, has awakened as the only "Reconstructor", who can touch the underlying code of the game, repair the lives of dying players, and tamper with cruel rules. He gathers awakened people with their own expertise to fight against order-type awakened people and high-level observers behind the scenes. He struggles to choose between rules and human nature. Using codes as blades and guardianship as his thoughts, he cracks the conspiracy of world destruction, reconstructs the broken reality, and lights up the light of hope for mankind in the midst of despair.
