Black clouds kept rolling, and pale lightning appeared intermittently.
On the hillside, a towering Demon Fortress stood tall, surrounded by patrolling Demon Army.
They formed squads of ten, holding torches, constantly wandering around the fortress.
Outside the fortress, behind a large boulder at the bottom of the hill.
A few demons were hiding behind the boulder, peeking out.
They were donned in demon standard armor crafted from the scales of Abyss Scale Armor Beast, emitting a strong evil aura. Their physique was relatively petite among demons, yet they looked quite slender.
They didn't seem like the demons evolved from the Abyss Nest, rather like some subhuman species from the material realm fallen and turned into demons.
The foremost demon glanced at the fortress on the hill and turned to his companions:
"Everyone, ahead is the Demon Fortress from Big Sister's mission."
After speaking, he looked at one of the demons and asked:
"Cyber, what should we do next?"
