After failing the civil service exam and coming up short in graduate school admissions, Xu Miao thought life couldn't get any worse. Then he was caught up in a hunt by the Eroded Puppets and discovered that the world had a hidden side: the ancient calamity Fei was awakening, and his parents had once been guardians. Bearing an unknown bloodline and wielding power he couldn't control, he entered a research institute alongside a group of fellow young guardians. Again and again, they were thrust onto battlefields where their lives hung by a thread. This is the extraordinary path of an ordinary person, and a story of being tempered into a beacon of light amid blood and fire.
