In the hierarchical Tianqiong City, Lin Yuanzhou, a waste recycler in Xiacheng District, lives a low-class life running around paying for his sister's medical expenses. By accident, the mysterious metal sphere he picked up from the scrap pile turned out to be the nanomechanical core left by ancient civilization. This "mechanical heart" gives him the ability to enlighten and transform all mechanical creations. Starting from a dilapidated maintenance workshop, he used scrap copper and iron to create a mechanical army with autonomous consciousness, challenging the giant corporations that ruled the city, and uncovering ancient secrets that had been covered by dust. Lin Yuanzhou will embark on the road to becoming a god step by step from the bottom of the city, using steel and circuits to create his own throne.
