In 2072, a disaster called "Entropy Silence" swept across the world. All equipment that relied on electricity was instantly paralyzed, and human civilization collapsed. Survivor Yun Suguang accidentally discovered that the "light trace" nanochip in his body was not only the target of the military pursuit, but also the key to restarting the world. In an apocalyptic world where mutated creatures are rampant and various forces are divided, he is forced to embark on an adventurous journey to find the source code of the chip. Along the way, he met the mechanical genius Su Wanxing and the mutant leader Huo Cang, but he also encountered many obstacles from the mysterious organization "Returner". As the truth gradually emerges, Yun Suguang discovers that "entropy silence" is actually a tragedy self-directed and staged by humans in order to control the rampage of technology, and his existence may determine whether humans will move towards a new life or be completely annihilated by the backlash of technology.
