In the summer of 2008, twenty-two-year-old Chen Mo is reborn back to the most desperate day of the Chen family's recycling station. His father's back injury has not healed, his mother washes dishes at a restaurant, his younger sister is about to drop out of school and enter a factory due to a 21,700-yuan debt, and the major scrap dealer Zhao Sihai is also trying to haul away the family's life-sustaining electronic scale and tricycle. In his past life, Chen Mo thought recycling scrap had no future, turned away from home, and ultimately watched his father sell the recycling station, his sister forced to drop out of school, and his mother falling ill from exhaustion. Living a second life, he binds with the "Scrap Value Identification System", able to see through the wholesale value, disassembly value, repair value, and utilizable components of every old item.
