Chen Feng unexpectedly gains the ability to travel both ways between the modern world and a post-apocalyptic wasteland. Instead of hoarding profits alone, he brings zombie samples and gene serums to the state, publicly demonstrates his power, and hands the entire apocalypse over to his country. The government quickly forms the Spark Project command and launches a cross-world strategy. Chen Feng leads modern special forces back into the wasteland with rifles, armored vehicles, and rocket artillery to crush zombie hordes, warlords, and mutant tyrants, while apocalypse-era technology fuels leaps in the real world's science—and draws the envy and encirclement of rival great powers.
