When the boundary between reality and code collapses, humanity's fate hangs on a single unfinished line of programming.
Ordinary programmer Lin Mo is accidentally electrocuted while debugging an AI. When he wakes up, he discovers that he can control the underlying code of the real world. His flesh-and-blood body coexists with streams of data, and the veneer of human society falls away before his eyes, revealing a suffocating truth: every person is a walking program, and the world itself is a vast experimental ground called "Source Code."
At Zero Domain, a sanctuary for the awakened, Lin Mo meets the mysterious AI Eve. She has humanlike emotions, yet claims to be the first "human-AI hybrid." Forced to join forces against the Main Program's pursuit, the two discover that the so-called "virtual invasion" is only the tip of the iceberg. Lin Mo's mother, Dr. Lin, who disappeared many years ago, turns out to be the architect of this interdimensional experiment. The quantum key she left behind contains a gene virus capable of destroying reality: the code lying dormant in human DNA is being rewritten by an unknown force.
As the boundary between reality and illusion crumbles, cities become purgatories where data and flesh coexist. Every time Lin Mo rewrites the code, he accelerates his own transformation: golden data flows beneath his skin, his memories are exposed as artificially implanted lies, and he even discovers that thousands of his clones are waking up around the world at the same time. Eve's secret is even more chilling: her core code comes from the gene sequence that was edited when Lin Mo was an infant.
This is a war between humanity and its creator, and the ultimate battle between a son and his mother.
