In a future continent where magic technology and steel behemoths coexist, humans rely on "magic suitability" to determine their class. Lin En is a rare person with zero fitness, who was abandoned to live in a polluted area where scrap metal accumulates. Until one day, he awakened an old talking mecha deep in the ruins. The mecha's screen flashed strange text: "The 'bloodline of the old gods' has been detected. Will it be bound to the God-killing armed system?" When everyone laughed at the useless man who could only associate with scrap iron, Linn drove the rusty steel giant and tore apart the mythical lies that had shrouded the continent for thousands of years.
