Tianjian Sect, the poorest sect in the cultivation world, takes in an abandoned little junior sister, only three and a half years old, on a snowy, windy night. Born with an affinity for demon beasts, she pets ferocious beasts as casually as cats. She sets up market stalls to earn spirit stones and repair the sect's protective formation. At the grand competition, her five senior brothers each take on five opponents at once, crushing them in spectacular fashion. An elder of Zixiao Sect unleashes the overwhelming spiritual pressure of a Nascent Soul cultivator, bearing down on everyone. The senior brothers use their own bodies to form a human wall, falling one by one. At the little junior sister's moment of life and death, she awakens through a phoenix-like rebirth and shatters the protective barrier with a single strike. Yuan Yin, the seal master behind the scenes, manipulates the various sects into besieging Tianjian Sect. After awakening in three colors and recovering her memories, the little junior sister discovers that she is the reincarnation of an ancient sword spirit who helped open heaven and earth—and Yuan Yin was the one who sealed her. In the end, she makes the same choice she made ten thousand years ago.
