On a thunderstorm night, Ma Sanniang resurrected from the water using the snow relics she had stolen from her master. After the resurrection, Ma Sanniang became disillusioned and decided to return to her master's school to look for her abandoned son.
Ma Sanniang returned to her master's school, but unexpectedly discovered a shocking secret. It turns out that a young man of about the same age as his son, the three-eyed Amu, lives next to the master on the snow island. He has the ability to subdue the legendary four beasts of wind, rain, thunder, and electricity, and finally find the unicorn! This secret revived Ma Sanniang's evil thoughts. An evil plan was brewing in Ma Sanniang's heart.
Ma Sanniang planned to murder her master and fabricated a beautiful lie - as long as she defeated the four beasts of wind, rain, thunder and electricity, she could find Amu's mother in order to control Amu.
