At fourteen, Song Qingning went to war in place of her cousin, shedding blood to achieve great military exploits. She won the title of heir for her cousin, begged a first-rank imperial title for her adoptive mother, and helped her cousin get conferred as a county princess to marry into a duke's mansion. She hoped for a shred of warmth from her adoptive mother, only to learn she was not her biological daughter, and ultimately ended up murdered along with her biological family, dying in bitter resentment. Reborn into a single moment, she returned to the time when she triumphed back to the capital and received her adoptive mother's letter. In this lifetime, she will never hand over her military exploits to others; the cousin's heir position, the adoptive mother's imperial title, and the cousin's glory—everything belonging to the senior branch, she will take back completely.
