Zhu Ganglie, the deputy commander of Tianhe Navy, discovered something strange in Tianhe while patrolling. He met Yunyao, a mysterious girl who stole Tianhe water. The two did not know each other.
Zhu Ganglie discovered that Yunyao was a Skylark Fairy who had become a spirit in the lower world. She risked stealing Tianhe water because her mother was seriously ill and needed treatment, and was moved by her filial piety.
