It wasn't that Xi Zhao's power was insufficient; rather, it was because the Annihilation Nine-Headed Serpent of the Patrolling Celestial World was simply too immense. It was far larger than any serpent Xi Zhao had known, heard of, or seen. Moreover, should the Annihilation Nine-Headed Serpent be fully resurrected, leaving aside the question of whether it could be controlled by Xi Zhao—even if it could be—the Patrolling Celestial Realm would likely be finished. The Heavenly Patrollers had already explicitly warned against any further explosions of the Heavenly Steles. Why issue such a warning? Was it because those Heavenly Steles were too precious? Of course not; it was because the explosion of a Heavenly Stele would cause massive damage to the Patrolling Celestial World, so the Heavenly Patrollers had no choice but to strictly prohibit it.
