There is a legend passed down among the people: In a mysterious village cut off from the rest of the world, known to the ancestors as Lingyin Village, lives a group of equally mysterious "people." Their lives are far longer than those of ordinary humans, and they are said to possess extraordinary abilities. No one knows what those abilities are. All anyone knows is that after helping the Heavenly Emperor defeat the demons in their battle, they chose to live in seclusion. Since then, there has been no word of them. Under the rule of the Celestial Realm, the human world enjoyed centuries of peace, until sixteen years ago, when the death of the War God Tianhe dealt a devastating blow to the realms of Heaven, Earth, and Humanity. That catastrophe even reached Lingyin Village. Sixteen years later, she became the key to preventing an even greater calamity. To do so, she had to grow stronger.
To become stronger, she followed her older brother to the human world, but they became separated in time and space. She, innocent and beautiful, found herself by his side.
