The wasteland scavenger "Ling" picked up half of a core chip in a rusted mecha cemetery, and after inserting it into the "King of Rags" made of scrap copper and iron, he actually activated the ancient mecha "Cang Yuan" that had been dormant for hundreds of years. When blood lines covered the fuselage, she discovered that the core of this abandoned war weapon actually sealed the consciousness fragments of the missing interstellar marshal "Kai". "Vera", the mechanic at the repair shop next door, always laughed at her for collecting scrap metal like building blocks, but when she was chased by a black market mecha hunter, she threw out a homemade pulse cannon: "If this junk metal could fly, I would live broadcast chewing wrenches!" And when "Cang Yuan" unfolded its streaming wings in the rain of meteorites, Ling saw the marshal's emblem exposed under the helmet of the pursuer - it was the symbol of Kai's last personal guard before his disappearance. From a scavenger girl to a warrior piloting a legendary mecha, she stepped on gears and sparks, but she didn't know that every roar of the abyss was awakening interstellar secrets buried by time, and those memory fragments embedded in the core of the mecha were dragging her into a fateful battle spanning light years.
