When Mo Xiaolan was five years old, her small village was hit by a beast tide.
Her parents and the other villagers were all killed by demonic beasts, and young as she was, she was about to meet the same fate.
A beautiful fairy sister suddenly appeared, killed all the demonic beasts, and saved her life.
At that time, Mo Xiaolan wanted to become her disciple, but the fairy sister said to her:
"What I seek is extremely dangerous, and the place where I belong is not accepted by the world, which may not be good for you."
Eventually, the fairy sister did not take her away and soon vanished gracefully.
But Mo Xiaolan always remembered the appearance of the fairy sister.
Although not as stunningly beautiful as the Three Great Immortals of the time, her temperament was incredibly cold and valiant, unmatched by others.
Later, Mo Xiaolan would intentionally or unintentionally imitate the fairy sister's valiant demeanor.
