This familiar pattern of a dead person coming back to life confirmed Wang Ling's guess.
Whether it was Bai Youquan, the son of President Bai, or Nightmare, whom President Qi had captured in Nine Dragon Pagoda, it was the same person pulling all the strings behind the scenes.
The profound truth of Fate Dao was to control life and death, to overturn the heavens and change one's fate; it wasn't just a simple resurrection spell. Xia Lixing had been resurrected, but the power of Fate Dao could rig it so that at a critical moment, any of the Xia Lixings in numerous parallel worlds could become his substitute and die in his place.
Thus, normal Heavenly Dao spells had no effect at all.
