In the future city "Dome City" where technology is highly developed and classes are solidified, Gu Chuanze, a maintenance worker living at the bottom, awakens in an accident the mysterious ability that can give machines "life" and "consciousness".
Starting from a humble cleaning robot, to abandoned industrial mechas, to a huge mechanical network covering the entire city... Gu Chuan Tze quietly built his own mechanical army.
Facing the oppression of the plutocrats, the indifference of the upper class, and the crises lurking deep in the city, Gu Chuanze and his unique "partners" will use steel and electricity to break through the shackles of class, uncover the hidden truth of the world, and finally move towards the boundless sea of stars.
