[Hunting to Support the Family + Building a Fortune + Martial Arts and Medical Skills + Power Struggles]
Song Jinzhao, a modern medical student, awakened supernatural abilities when the apocalypse arrived and joined the base defense force, receiving special forces training.
Suddenly transported to another world, she finds the original host's father was killed by falling rocks while building a canal for the imperial court, and the mother, unable to bear the shock, died during premature childbirth, leaving behind a newborn infant and a pair of ten-year-old twins, a boy and a girl.
The eldest and second uncles refuse to adopt the four children, deciding to give the still-swaddled youngest brother away to outsiders and marry off the ten-year-old sister as a child bride for a sickly boy in a "fortunate marriage" to cure his illness.
Having been an orphan since childhood, Song Jinzhao yearns for familial bonds and decides to raise her three younger siblings alone, also as a way to repay the debt for occupying the original host's body and gaining a second chance at life.
Several years later...
The prodigy Tanhualang (top graduate) of Dongzhao Kingdom declares: "My elder sister is a master of both letters and martial arts; she can serve in the imperial court and pacify the realm. She is the number one female general of Dongzhao."
The empire's foremost divine female physician says: "My elder sister is actually the world's number one miraculous doctor."
A four-year-old child holding a golden abacus raises a hand and chimes in: "Elder sister, I want to make money and become the wealthiest person in the world."
