Luo Mingxin, the number one genius of the Sword Sect, was born with a sword body. When choosing a sword in the Sword Tomb, her junior sister Bai Nishang snatched her destined divine sword. In a desperate situation, she used her vital blood to bind an ancient rusted sword, attracting mockery from the entire sect. No one knew that this sword harbored a powerful sword spirit and possessed countless top-tier sword cultivation techniques. The sword spirit helped her break through her cultivation realm, shattered the sword technique coveted by Bai Nishang, and resolved successive crises. Bai Nishang and her mother plotted in secret, forcing her to descend the mountain using family letters. Carrying the ancient sword, Luo Mingxin stepped back into the mortal world, faced cold-hearted family members and layer upon layer of schemes, and turned around every dilemma with her sword power.
