The glory of the "celestial beings" civilization turned into "ruins" of disaster all over the earth overnight. The giant cities that once connected the heavens and the earth have become nests that breed aberrant monsters; the endless energy that once drove civilization has dissipated into deadly and tempting "spiritual dust".
This is the worst of times and the best of times.
The survivors established a new order on the ruins. They breathed spiritual dust, tempered the inner skeleton called "spiritual bones", and ate from the remains of the old world, competing for every resource to survive.
Chen Gu, a "scavenger" at the bottom of Steel City, is a gray mouse who earns a living in the "market" by cheating and coquettishly. His biggest dream is to save enough money to buy a better prosthetic lung so that he can stay in a place with a higher concentration of spiritual dust for a while.
Until that day, he found a warm, breathing metal fragment from the chest of a "celestial being" skeleton.
From then on, the truth and lies of the world, the glory of the past and the destiny of the future, were like rusty gears, surrounding him, making a tooth-breaking sound.
"Don't talk to me about saving the world," Chen Gu faced the various powerful men who were chasing him and the monsters crawling out of the "ruin", and shouted back as he ran, "I'm just a garbage collector! - Hey, the one in front of you, put down the treasure in your hand, or I'm going to scold you!"
