Preparation to breakthrough Tier One Wizard

Aur sat calmly, legs crossed, his expression serene and undisturbed by any external turmoil. His waist-length white hair cascaded around him, adding to his air of tranquillity.

The mana in the surroundings seemed unusually active, swirling around him in intricate patterns.

In front of him, two middle-grade mana crystals lay, their energies being steadily refined by Aur with meticulous care, each refinement conducted with unwavering focus.

Suddenly, Aur's eyes snapped open, a bolt of lightning seemingly flashing within them. Despite the intensity of the moment, a small smile tugged at the corners of his lips.

"At last," he murmured with a sense of fulfilment.

Within his mental space, a sense of completion washed over him as every corner was filled to capacity with colourless mana, reaching every nook and cranny.
