In the "Seventh District" of the future city where technology is highly developed and the gap between rich and poor is huge, low-level waste picker Lin Yuanhang struggles to survive. In an accident, he fell into a forgotten underground restricted area and awakened an old-era super base called "Tiangong". Lin Yuanhang, who has been bound to the base's highest authority, has acquired technological power far beyond the times - from nanorobots to smart factories, he can do everything. Faced with the oppression of the outside world, the covetousness of the plutocrats, and the crises lurking in the shadows of the city, Lin Yuanhang decided to use the "Tiangong" base to start from an unknown scavenger, step by step, establish his own order, uncover the dust-laden truth of the world, and eventually become the sole master of the new era.
