Those lines of cause and effect that entwine her, are prophecies affecting her choices, or are she creating the future through her choices... ———— Voldemort's perspective Family members, who knows, I met a naughty woman! Chasing other people's Tianling Gai every day! But I was reborn. Last time I died in the hands of a little girl. This time I must take back everything that belongs to me... Many years later, Voldemort was reborn again: Little sister, please slow down, my brother's Tianling Gai won't run away.
