Shen Biluo died with hatred in her heart. Somehow, she became a ghost confined to an unknown place. As time passed, she forgot herself and her hatred, and no longer knew why she existed. At last, she became a spirit and was transformed into a sword spirit. She has no idea how much time has passed. Now, her reason for existing is to protect that girl and her home. This is the mission of the Biluo Sword, and the lifelong wish of Shen Biluo.
That's it? That's it. It's gone.
