"Boom!"
With a loud crash, the zombie had already blasted a large hole into the mountain wall, enduring the attack above its head, its body emitting swirling black smoke and drifting corpse qi as it charged into the mountain's interior space.
"Corpse army, awaken all three thousand ironclad corpses for me!"
The zombie waved its hand, sending a swirl of corpse qi toward the ritual altar in the center of the mountain space.
Only...
"Where's the corpse-controlling banner?" The zombie was dumbfounded.
Within the cavern space of the mountain, quietly stood three thousand blue-grey bodies clad in dark iron armor, some holding long spears, some with swords and shields, others drawing strong bows, and even three hundred corpse-riding skeleton horses.
However, these three thousand iron corpses showed no sign of breath or divine soul fluctuation. In front of them stood a half-human-high altar, but the banner supposed to control these iron corpses was nowhere to be seen.
