Alien machines are parasitic and the world has become a "harvest field". In his previous life, Jiang Li was imprisoned and dissected for three years as a top-level experimental subject, and eventually died together with the laboratory. Reborn on the eve of the disaster, she awakened the "Civilization Fire System" and brought with her a foldable space that can evolve infinitely. One million cash? All replaced with special steel and high-precision weapons! Top chaebol? Their arsenal is nothing but my personal storehouse! While everyone was desperately struggling in the tide of alien weapons, Jiang Li was sitting on a steel fortress, cutting space with his left hand and bombing the system with his right hand. She is the only law in this wasteland: those who stand in the way will become enemies; those who obey will survive.
