Chapter 686: Divine Intervention      

Ren faced the devils with a calm demeanor, conserving his mana for the challenges ahead. 

Instead of launching lethal spells, he focused on deflecting their attacks, using simple yet effective incantations to keep them at bay.

His strategy didn't involve annihilating the devils; he knew that for every one he defeated, more would swiftly replace them, so there was no use in killing them.

Ren understood the futility of a battle of attrition in this demonic horde. So, he opted for a tactical approach, parrying their strikes and employing minimal magical force, reserving his energy for the crucial moments to come.

Meanwhile, Princess Lorelai continued her fierce duel with Asmodeus. With every clash of their weapons, sparks flew, illuminating the chamber with brief bursts of celestial light. 

Sweat trickled down her brow as she exerted herself, her Valkyrie form radiating determination.
