From condemned prisoner to general, every step Shen Qingli takes is on the edge of a blade. At the execution ground, she refuses to beg for mercy; on the frontier, she refuses to accept her fate. When grain records are falsified, she uncovers the truth page by page. When an isolated city is about to fall, she leads the elderly and the weak in farming to save themselves. When enemy cavalry threatens the border, she uses strategy to protect the lights of the entire city. When her father is wrongfully accused, she investigates to the very end, determined to restore his innocence before the world. She has been afraid, and her hands have trembled, but she has never retreated. Because she always remembers her father's words: A blade is meant to protect people, not to stand in their way. Wind and sand can bury footprints, but they cannot bury the light in a person's heart. The blade points outward to protect those behind it. No matter how difficult the road, every step must be taken on the right path.
