After transmigrating into the apocalypse, Lin Lan finds herself in a world where a superpowered battle game has become reality. Outside the high walls, high-level zombies run rampant.
At eighteen, she awakens and is offered two top-tier options, Rocket Boy and Explosive Bunny, but resolutely chooses the useless class, Source Code.
She is mocked from every side, abandoned by her lover, and becomes the laughingstock of the whole school.
No one knows the true power of Source Code.
Mechanical mines control hordes of zombies, data-based intangibility lets her escape death, and reconstructed supplies never run out.
When the zombie tide surrounds the city, the joke everyone once laughed at will become the apocalyptic god of source code.
