John acted with remarkable speed once the plan was set, utilizing the Book of the Astral Realm to launch his assault.
He chose not to employ his customary spells for this initial attack, keen on concealing his identity from the onset of the confrontation.
Instead, John opted for a wind-based god-tier spell, a tactic previously unutilized by him.
With the amplification provided by the Book of the Astral Realm, the god-tier wind spell was significantly empowered.
A fierce gale surged through the Dark Realm towards Styx town, an unprecedented phenomenon for its defenders.
The town's outer defensive arrays were swiftly demolished, and a majority of the demons assigned to guard were eradicated.
Witnessing the success of John's initial strike, Duke Arsena and Natasha commenced their own attacks.
