What if after Bai Zihua had killed Little Bone, her soul burst out in thousands of dust like sparkles that were captured by the sword? Her soul blends with the sword and she becomes the spirit of the Sympathize Life Sword. Hua Qiangu is alive even if she is a sword now.. However, she is unable to feel due to the fact that every emotion was destroyed once with her soul.

Once in life any human may wish to turn back the time and fix the errors he'd made. The question is "Were you to go back to time, would you make things differently?"
