Still under the physical and mental impact of the exhausting battle fought against the obsidian colossus in the heart of the rocky labyrinth, the squad gathered around the newly unlocked portal to organize the final preparations before crossing the border into the thirty-third floor. The ornate dark-metal key that the boss had left as spoils fit with millimetric precision into the runic lock embedded in the stone wall, emitting a deep and harmonious click that preceded the slow and majestic movement of the great doors opening to reveal the tower's new sector. As soon as the mechanism completed its cycle, a blast of icy and cutting wind escaped through the cracks of the newly opened portal, striking our faces with a brutal cold that strongly contrasted with the stifling warmth of the rocky galleries we had just left behind.
The climatic change was immediate, drastic, and relentless. Without the slightest gradual transition, the air around us transformed into a freezing mass that caused the breath of every member to instantly condense into clouds of white vapor beneath the diffuse light of the environment. Liriel's assistant was the first to shiver slightly from the thermal impact, crossing her arms over her chest and adjusting the thermal protection layers around her garments with quick movements. I allowed a serene and analytical thought to occupy my mind as I observed the new landscape unfolding directly before us: rapid adaptability in the face of environmental upheavals is what separates a group of ordinary adventurers from a true living legend, because nature and the dungeon do not negotiate conditions with intruders; it is up to us to instantly adapt to the demands of the terrain or perish beneath the merciless weight of the elements.
"Incredible..." Scarlet murmured, releasing a long sigh that dissipated into the icy air as she ran the palms of her hands over her own arms to stimulate blood circulation. "We went from a furnace of stone and dust straight into the heart of an eternal winter in a matter of seconds. If we keep marching in these light clothes, our muscles will freeze before we even find the first monster."
"The drastic thermal variation between the floors of this tower follows a pattern of large-scale mana manipulation," Liriel explained, raising her runic staff so that its crystalline tip emitted a soft light, revealing the expanse of the immense ice plain stretching beyond the portal. "The entire ecosystem is artificially sustained by magical cores hidden deep below. We need to equip ourselves properly against the cold before taking another step."
"Good thing I anticipated this possibility when organizing the supplies in the magic bag before we left the mansion," Elara interjected with a confident smile, opening the spatial compartment to begin distributing reinforced thermal blankets and fire- and freezing-resistance potions to each of the girls. "We have garments lined with dragoness fur and enchanted wool that keep body temperature stable even in environments below absolute zero."
The mutual assistance among the companions as they put on the thermal clothing and adjusted the protections against the wind transformed that moment of climatic difficulty into an affectionate act of unity and collective care. Vespera and Lyannis helped braid the protective cloaks around Rai'kanna's and Liriel's assistant's shoulders, while Scarlet helped me secure the reinforced leather straps to my combat boots. This constant synergy strengthened our bonds invisibly, proving that the affection and solidarity we kept alive within the group were weapons as powerful as any magical sword or mass-destruction spell when facing the dangers of the depths.
With the clothing properly adjusted and body temperature normalized thanks to the warmth provided by the special garments, the squad rigorously aligned itself in the standard tactical formation — Scarlet at the vanguard, followed by Liriel's assistant, Rai'kanna, Elara, Vespera, Lyannis, Liriel, and me at the rear — and crossed the threshold of the portal, entering the thirty-third floor completely. The scene that presented itself before us was one of colossal and frightening beauty: an infinite expanse of frozen plains, translucent ice stalagmites reflecting the bluish glow of the vaulted ceiling, and snow-covered mountains that seemed to touch the tower's ceiling. The wind howled through the glacial crevices, singing a melancholic and lonely melody that seemed to echo directly in the depths of our souls.
We advanced with firm steps over the compacted snow, attentive to any fluctuation in the thickness of the ice crust covering the ground. The second dense magical stone we had collected on the previous floor rested safely at the bottom of the magic bag, emitting a subtle warmth that seemed to resonate in harmony with the mana of the new environment, reinforcing my conviction that these gems held a crucial secret about the Demon King's plans. As we ventured deeper into the frozen plain, the silence around us was suddenly broken by a dry and sharp crack coming from the snowy hills ahead, indicating that the initial calm was about to give way to new and icy challenges.
