The story starts from the "counter-time flow" of the protagonist Gu Chengyi who travels from the future to the 21st century. It extends the concept of "Three-body" from alien civilization to three types of marginalized groups in human society - marginalized groups, vulnerable groups, and extremely poor groups. Through the "Three-body Fund" and "Three-body Town" projects, a grand journey about redemption, civilization reconstruction and belonging to the universe begins. Finally, on a lonely planet light-years away, a new home was opened up for the "Three-body" group, completing the counterattack from the edge of society to the center of the universe.
