Three-Body Derivative × Doomsday System × Hardcore Survival
The zombie frenzy broke out, but I found them lining up with guns.
This is not a natural disaster, but the "silicon-based cleaning" performed by the Trisolaran civilization on humans. When the cannons of the living corpse army were aimed at the last fortress, all survivors fell into despair.
And I am bound to the [War Agent System] of the four-dimensional civilization. By killing living corpses, you can redeem points for future technology—from rifles to mechas, from EMPs to Star Destroyers.
Do they want to erase human civilization? Sorry, my final answer to this test of civilization's survival is a stellar bomb that I lit with my own hands.
