Once a wreck crawling out of a stardust scrap pile, Lu Jianshen was regarded by the entire galaxy as a useless war outcast. Until he was dragged out of the scrapyard by Yun Jin, the shadow commander who was as cold-blooded as the Quantum Blade, and forcibly injected with the "God-Killing Core". One of them carries an erased past, and the other swallows up the souls of countless traitorous generals. When the Galaxy Federation launched the "Light Extermination Plan" to clean up all war machines with non-purebred genes, Lu Jianshen and Yun Jin teamed up to tear apart the mask of order. They are not heroes, they are tyrants forgotten by the system. They use their scrap metal bodies to ignite the fire of revenge across the galaxy.
