我和殭屍有個約會3：永恆國度 (2004)

In ancient times, the immortal Fuxi, the King of Humankind, desired to create a paradise called the Eternal Country in the human world. However, he came into conflict with his lover, the goddess Yaochi Shengmu (Holy Mother of the Shining Lake), because the latter's mission is to bring death and disease upon humankind. Fuxi eventually broke up with Yaochi Shengmu and started a new relationship with Chang'e under his alter ego, Houyi. However, he lost Chang'e when she flew to the moon after consuming a magic pill from Yaochi Shengmu. Fuxi blamed Yaochi Shengmu for separating him and Chang'e, and fought with his ex-lover. The elders of the Pangu clan intervened by imprisoning Yaochi Shengmu in Heaven while Fuxi remains in the human world. Fong Tin-yau and Ma Siu-ling are living happily in Heaven after their success in 2001. However, in 2004, Yaochi Shengmu breaks free and introduces a deadly virus to wipe out the entire Pangu clan.
