In 2127, in the wasteland after the nuclear explosion, humans retreated to the steel fortress, struggling to survive between radiation and mutant beasts. Scavenger Lin Shen is an ant at the bottom of the fortress, making a living by rummaging through ruins.
After an accidental near-death, his heart was implanted with a mysterious energy core of unknown origin - the "Fire Source". It can bring abandoned machinery back to life, it can swallow radiation and turn it into power, and it also hides a blueprint for mechanical evolution that transcends the times.
From an armed chariot made of scrap metal to the ultimate mecha that tears apart the sky - Lin Shen embarked on a path to crush all oppression.
The predators regarded him as prey, and the higher-ups wanted to dissect him for study, while the mysterious Fire Church secretly watched. However, no one knew that the fire burning in his heart would ignite the entire wasteland.
