The Saintess's Revenge

Saintess Lyra, a Nine-Skies Azure Phoenix, uses her divine power to help her lover Kael ascend to godhood. Kael secretly fathers a divine heir with fox demon Sylvie, intending to abandon Lyra and marry Sylvie. Lyra lays down the Nirvana Grand Formation. On his ascension day, the formation activates, injuring Kael, and Lyra reclaims her divine power. This awakens the Ancient Fallen God, Zane, sealed for a thousand years.
