Song Zhiyu, the legitimate daughter of a distinguished military family, was once the only female general in the empire. But after mistakenly trusting someone close to her, her entire family was falsely accused and exiled to a bitterly cold land. At the brink of despair, she unexpectedly gains the extraordinary ability to travel between two worlds. In another world, she earns her keep through hard work, exchanging her labor for food and medicine, and single-handedly sustains the lives of more than three hundred members of the General's household. Faced with difficulties and schemes, she no longer relies on her fists. Instead, she uses her intelligence to gather evidence and fights back with the truth, gradually leading everyone home with their dignity intact. As the mystery surrounding her identity, hidden for eighteen years, is gradually unveiled, old grudges, family affection, and reconciliation intertwine in a revelation far more moving than she ever imagined.
