Unknown to outsiders.
The Super-Vibration Structural Destruction Cannon created by the Metal Destroyer Civilization for low-level Sacred Mark Wizards required its space-time lock-on anchor point to be embedded in advance. This was space-time technology Huadi Quantum Technology had cracked based on the wizards' spatial-temporal abilities. The Metal Destroyer Civilization was likewise studying the Wizard Civilization system!
The Heavenly Mountain Sea World had received a total of six legions dispatched by the Aikesmo Guild. For a mere medium-sized world to be invaded by such an astonishing number of Void robot legions—had Green, this "ancient wizard," not descended through the altar, the wizard forces of the entire world would already have been completely wiped out.
Boom! Boom! Boom! Boom! Boom! Boom! Boom! Boom...
The Super-Vibration Structural Destruction Cannon required an anti-gravity metal fortress as its foundation, its diameter and volume enlarged to provide the immense energy source it required.
Crash, crash!
Rolling waves surged skyward. Above the dark clouds hung pink blotches of light, filtering down through thin cracks in the oppressive cloud cover.
Crackle, crackle!
Water-lightning arcs occasionally fell from the clouds, striking either the legion monsters wreathed in black flames or the fluorescent green seawater, which had been diluted somewhat. They purified small patches of polluted seawater, restoring them to clarity.
"Hehehehe, this is the first time Master has summoned us, and those idiots are already finished."
A Bone Demon monster with two heads growing from its chest watched several other Bone Demon monsters plunge into the sea after being struck by the Void Mothership's main cannon, then let out a cruel "hehehehe."
The monster immediately beat its wings, dodging a pale violet particle cannon blast.
Strands of black flame drifted from its wingtips. The humanoid Bone Demon monster turned its eyes toward the source of the particle cannon fire.
