A sharp sword, carrying endless icy radiance, slashed down with the force of the heavens collapsing, leaving one unable to summon any will to resist!
The sword could not possibly have been as large as a mountain.
Yet the unstoppable momentum emanating from the descending blade created an illusion, as though a towering peak were crumbling before their eyes!
Even though it was only a memory, Dumbledore and Amosta were stirred into action, instinctively raising their wands.
But Slytherin before them seemed to have anticipated this move long ago.
His deep-set features remained calm, with only a trace of helplessness flashing through his pale green eyes. At some point, a serpentwood wand with a hollow-carved handle inlaid with gold patterns had appeared in his palm.
Without any visible motion from the wand, the head of a Basilisk—lacking a body, possessing only a savage serpent's head—blocked the path of the descending blade.
With a crisp clang, two rows of sharp, serrated fangs within the Basilisk's gaping maw clamped down on the gleaming blade.
In a single breath.
The blade trembled slightly, then suddenly erupted with incomparably brilliant crimson lightning. Beneath that overwhelming power, the Basilisk's head shattered inch by inch, turning into black smoke!
The lightning-clad blade continued downward, effortlessly tearing apart Slytherin's phantom.
Slytherin vanished, and so did the half of the blade that had extended from the void.
Yet the duel did not stop!
At the center of the room, blanketed by dense crimson lightning, an "absolute domain" appeared, isolated by hundreds of emerald starbursts as pure as gemstones!
Within the domain, all lightning was dissolved!
Amosta's lips twitched as he watched the domain.
Clearly, the "teaching material" the founder of Slytherin House had left for him in the underground vault at Gringotts had been a watered-down version.
