Interstellar Scavenger, Eating Government-Issued Meals in the 1970s

A young girl who scrapes by scavenging on a garbage planet transmigrates to the 1970s and thinks she's landed in paradise. People in this era are so lucky: they have more natural food than they can eat, and as long as they're willing to work hard, they can support themselves.

Her older sister doesn't want to go to work and insists on moving to the countryside. What a waste! She has such a good job at the recycling station, and she doesn't appreciate it! Since her sister insists on moving away, the girl takes over the job. Turning trash into treasure is something that's ingrained in her bones.

Telephones, TVs, electric fans, refrigerators, air conditioners, washing machines... All those things are child's play. For Feng Xiaoxiao, it's computers, spaceships, mecha, and robots.

Give her a mountain of garbage, and there's nothing she can't piece together.

Gradually, Feng Xiaoxiao begins to feel that something is off. She's only recycling waste and putting it to use, so how did she become a national treasure?
