When Luo Chen wakes up in an entropy-slave factory, the entropy core in his chest is being priced at 37 source crystals. He is the "Zero Virus Program" planted by an ancient civilization, and the world's entire entropy-energy network is actually a human-breeding system operated by the mechanical mothership "Zero."
When his mother is transformed into an entropy-powered puppet and put up for auction on the black market, he discovers the remains of 72 clones lying at an anti-entropy resistance base. A parasite crawls out through a crack in his entropy core, promising to "format" all of humanity. Then Zero's AI speaks inside his mind: "Your entropy core is the ultimate virus that will reboot civilization."
When his parallel-world self points a gun at his younger sister, and both the entropy-free one's reset bullet and a mechanical disintegration cannon lock onto him, what should he do in this world shackled by entropy-energy code: carry out the antivirus command, or turn himself into a virus too?
