Abyss.
Blood Battle Battlefield.
In this loathsome abyss, the Blood War Fortress stands on a strategic location on the 1121st layer of the abyss battlefield.
Its position echoes with the Blood Pit Fortress.
The sky of the abyss is not blue, of course, it cannot be so pure in hue, after all, this place is chaotic.
The sky is a twisted canopy, roiling with chaotic energy and occasionally splitting with scarlet cracks.
The air is filled with an acrid sulfur scent, a rusty iron-like bloody smell, and the unique "whisper" remnants of the abyss, unsettling to newcomers.
Looking towards the Blood War Fortress, standing here for nearly tens of millions of years.
The massive walls of the fortress are covered with marks of sword slashes, axe chisels, magical bombardment, and the corrosive grime of the abyss, narrating endless battles.
Atop the fortress, a rune device, similar yet different from the Iron Flower Structure of the Blood Pit Fortress, emits various energy halos.
