The fourth day of exploration beneath the suffocating canopy of the underground forest ended abruptly when the moss-covered terrain and twisted roots gave way to a vast circular clearing surrounded by natural walls of dark basalt rock. At the exact center of this stone amphitheater, the guardian of the thirty-sixth floor awaited us: a colossal humanoid arboreal entity known as the Patriarch of the Withered Vines, whose thick, twisted branches emitted a pulsating aura of dark-green mana. The battle was intense, requiring the perfect coordination of all the squad's abilities. While Scarlet and Rai'kanna cut through the reinforced wooden defenses with devastating blows, Vespera and Lyannis conjured spheres of concentrated fire to neutralize the thorny tentacles that attempted to ensnare us. With a decisive and precise movement, I delivered the final blow that shattered the mini-boss's core, causing the colossus to crumble into a shower of luminous particles.
Reflecting on the victory and the conclusion of that stage in the jungle, I understood that persistence in the face of the unknown is the true driving force that propels adventurers toward the top. Overcoming the green labyrinth required not only brute strength, but also the ability to maintain mental focus when physical exhaustion threatened to cloud judgment. Beside the monster's disintegrated body rested the crystal leaf-shaped runic key, the indispensable magical artifact needed to unlock the colossal portal embedded in the basalt wall at the back of the clearing. Liriel calmly approached, carefully picked up the key, and inspected the inscriptions engraved on the relic, confirming that the route to the thirty-seventh floor was officially open for our passage.
"Excellent teamwork once again," Scarlet celebrated with a radiant and victorious smile, wiping the sweat from her forehead with the back of her gloved hand while sheathed her sword. "I admit that big wooden guy tried to give us trouble during the first few minutes with those treacherous roots, but watching him crumble into magical dust makes up for any back pain accumulated over the last few days."
"The credit belongs to all of us, for keeping the formation aligned even under the pressure of the humidity and fatigue," Liriel pointed out in her serene voice, approaching the immense stone door to insert the crystal key into the central slot. "The records indicate that the transition to the next floor will take us to an environment completely opposite to the one we left behind. The thirty-seventh level is famous for its mountainous topography, cutting winds, and deep ravines."
"Mountains and ravines?" Elara repeated, adjusting the straps of her heavy backpack and checking the supplies of thermal stabilization potions. The alchemist looked around with an analytical expression before continuing: "That means we will have to deal with unpredictable air currents and slippery rocky surfaces. I will prepare an extra batch of grip ointments to ensure complete firmness in our boots during the climbs."
"Elara's preparation is always impeccable," Vespera praised, extending her hands to warm them slightly with a lesser flame spell as the runic portal began to rotate with a deep and deafening metallic sound. "With the strong winds typical of that sector, any imbalance can be fatal. We will need to double our attention to our footholds when crossing the suspended natural bridges."
As soon as the crystal key fully turned in the ancient lock, the immense basalt door slowly opened, revealing a corridor illuminated by a cold, bluish light that contrasted sharply with the oppressive green of the underground forest. A gust of cold, dry wind blew through the opening, carrying with it the characteristic scent of polished rock and high altitude. Without losing a single moment, we aligned our tactical formation and crossed the threshold, definitively leaving the thirty-sixth floor behind to enter the rocky and vertiginous domains that made up the thirty-seventh level of the tower.
The environmental transition was immediate and impressive. As soon as our steps touched the gray stone floor of the new sector, the organic forest disappeared completely, replaced by a monumental ravine carved by endless abysses and natural stone bridges that snaked between steep cliffs. The ceiling of the cavern here was so high that it disappeared into the gloom, giving the illusion that we were beneath the open sky of a harsh winter night. The wind howled through the cracks in the rocks, producing a deep and continuous sound that seemed to sing a melody of challenge to anyone who dared to set foot at those heights.
"What a fascinating and challenging place," Rai'kanna murmured, her attentive eyes examining the rocky horizon with extreme concentration as she assessed the possible routes upward. The wolf warrior took a few firm steps across the solid ground of the entrance platform and continued in her firm tone: "Visibility here is excellent compared to the dense forest, but the lateral wind can destabilize the balance of anyone carrying excessive weight. I recommend that we keep our bodies low when crossing the narrower passages."
"Rai'kanna is absolutely right about the wind," Lyannis agreed, drawing her secondary blade to test its edge against the icy breeze circulating through the environment. "If there are flying creatures lurking around these cliffs, they will have the advantage of the wind's inertia when diving down upon us. We need to keep our eyes firmly trained upward."
"That is exactly why our progression will be cautious and methodical," I declared, taking the lead of the march while adjusting my cold-weather cloak to protect myself from the freezing gusts striking our group. "We are not in excessive haste; the absolute priority is to ensure the safety of every member while we map the topography of this new sector. We will advance in single file along the edges of the cliff, maintaining constant communication."
The march through the thirty-seventh floor required a radical change in pace and physical posture. Every step on the rocky ledges had to be calculated to the millimeter to avoid slipping on the cracks covered with stone dust. The sound of our boots mixed with the constant echo of the wind, creating a rustic symphony that accompanied our gradual ascent along the slopes of the underground mountain. Thoughts about the grandeur of that ancient structure crossed my mind, reinforcing the conviction that every floor overcome represented not only physical progress toward the top, but also a profound refinement of the spirit and unity of our squad, preparing us to face whatever destiny awaited us in the unknown depths of the tower.
