The surge hit like a tidal wave.
Nathan's mana channels, still adjusting to the D-Rank expansion from the primer, were suddenly forced wider. Deeper. More efficient. The refinement formula tore through him like liquid fire, burning away the last remnants of the F-Rank ceiling and replacing it with something new. Something powerful.
His Bunny Girl System blazed with warnings:
[WARNING: Foreign mana detected.]
[WARNING: Mana channels expanding beyond baseline parameters.]
[CRITICAL: System stabilization failing.]
[CRITICAL: Aptitude threshold being exceeded.]
The pain was excruciating—worse than the primer, worse than the mace in the Whispering Dark. Nathan fell to his knees, his body trembling. His summons surrounded him, their presences blazing through the link, lending him their strength.
[DING! Magical Aptitude Increased!]
[D-Rank → C-Rank]
The surge didn't stop. It kept pushing. His channels stretched. His core blazed. The walls of his limitations crumbled.
