The instant the console screen lit up, the purple-red glow at the muzzle of Anrokuzan's main cannon reached its critical point.
The violent high-energy beam erupted with a deafening roar. The purple-red pillar of light swept across the underground hall in a fan-shaped arc. Wherever it passed, the metal floor instantly melted into boiling iron. The air was forcibly ionized, and the extreme heat triggered a violent backdraft.
Under the continuous onslaught of intense heat, the granite pillar began to vitrify across a wide area.
