The end of our first night of camping in the depths of the tower passed without any kind of unwanted interruption, allowing the entire squad to awaken refreshed and with their energy fully restored for another day of marching. In the first hours of the morning, we dismantled the improvised refuge in the circular chamber, organized our personal equipment, and checked the condition of the magic bag, which continued to perfectly preserve the essential provisions for our survival. We resumed our strict advance formation, with Scarlet in the vanguard followed by Liriel's assistant, Rai'kanna, Elara, Vespera, Lyannis, Liriel, and me closing the rear with firm steps. The sepulchral silence that had marked the previous floors began to slowly dissipate as we advanced through the stone corridors, giving way to a drastic change in the architecture and atmosphere of the environment around us.
After walking for about four hours through increasingly humid galleries, the dry stone structure gave way to vast stretches of crystal-clear water that reflected the pale glow of the magical crystals attached to the extremely high ceiling. We were finally entering floor 28, a unique sector of the dungeon characterized by deep underground lakes and a complex network of interconnected stone bridges that snaked above the dark waters. The constant sound of dripping and the soft murmur of the flowing water created a peculiar acoustics, causing any noise to travel long distances. Looking at that liquid expanse brought an immediate sense of alertness, because the basic logic of the dungeon dictated that aquatic environments housed creatures adapted to stealth hunting and surprise attacks from the depths.
"The humidity here is dense enough to affect the combustion of some fire spells if we don't channel extra energy," Elara observed, adjusting her glasses and slightly furrowing her brow as she examined the light vapor rising from the surface of the water. "We need to be twice as careful when crossing these narrow bridges. If we're targeted by a combined attack from the water, our room for maneuver will be extremely limited due to the reduced width of the stone paths."
"Elara is absolutely right about the limitations of the terrain," I agreed, stopping for a moment at the entrance to the first large bridge to inspect the length of the route ahead of us. "The design of these floors was deliberately made to disadvantage large groups and force outnumbered battles at choke points. But our chain formation was designed precisely to neutralize this type of spatial trap. Scarlet, maintain a steady pace, but check the ground every three steps for pressure mechanisms."
"Leave it to me, Takumi," Scarlet replied with a confident smile, testing the firmness of her boots against the bridge's damp slabs before advancing with surgical caution. "No cheap trick will catch us by surprise while I'm leading the front line."
The group advanced orderly across the stone bridge, whose sides had no protective railings, making it clear that a fall into the waters below would result in severe complications or a direct confrontation with the native inhabitants of that underground lake. With every meter traveled, the atmosphere became heavier and filled with a freezing humidity that clung to our clothes and skin. As we walked in concentrated silence, I allowed a reflective thought to occupy my mind for a few moments. A leader's true strength is not proven only in moments of glory or when victory is evident, but rather in the ability to maintain serenity and mental clarity when the terrain openly conspires against his group. Every challenge overcome in those depths sculpted not only our reputation, but the very essence of our unity.
As we approached the exact center of the crossing structure, where the main bridges intersected, forming a circular plaza suspended above the waters, the surface of the lake began to bubble intensely. The peaceful sound of the currents was suddenly replaced by a muffled roar that echoed through the cave walls, causing all the water around us to churn as if it were boiling. The strong smell of slime and stagnant water invaded the air, instantly confirming our suspicion that the calm had abruptly come to an end.
"Immediate combat formation!" I ordered in a firm voice, drawing my sword with a quick movement that made the steel gleam beneath the blue light of the crystals. "They're coming!"
Before the echo of my voice could completely dissipate, five colossal humanoid creatures burst simultaneously from the depths of the water, leaping with impressive agility onto the stone platform where we stood. They were beings with bluish, scaly skin, equipped with pulsating gills on their necks, razor-sharp claws, and disproportionate jaws filled with pointed teeth. They belonged to the race of amphibious warriors of the depths, monsters known for their brutality in close-quarters combat and formidable resistance against conventional physical attacks.
The ambush was executed with surgical precision by the creatures, which attempted to surround the group by dividing the central platform and cutting off our escape route both forward and backward. However, our collective response was infinitely faster than their ability to react. Scarlet did not retreat a single centimeter; with a swift turn of her body, she intercepted the first amphibian that leaped toward her, driving the enchanted dagger directly into the weak point between the monster's chest scales with relentless force.
"You chose the wrong place to set an ambush!" Scarlet exclaimed with a gleam of excitement in her eyes, pushing the inert creature off the platform and sending it plunging back into the dark waters with a dull thud.
Behind her, Liriel's assistant and Rai'kanna formed an impenetrable barrier. Rai'kanna swung her short spear in a perfect horizontal arc, delivering a devastating blow that struck the second monster head-on, throwing it against the side rock wall and opening space for the rest of the group to maneuver safely. Vespera and Lyannis instantly conjured elemental support and containment spells, creating a compressed-wind barrier that prevented the next two amphibians from advancing toward the left flank where Elara and Liriel were preparing large-scale spells.
My blade cut through the air in a brilliant silver arc as the fifth monster attempted to leap directly over my rear guard, seeking to strike me from behind. I channeled a controlled fraction of my internal energy through the sword's hilt, delivering a vertical blow that broke through the creature's defense with absolute ease and neutralized it instantly. The battle on the narrow bridge was short, violent, and extremely dynamic, requiring sharp reflexes and absolute coordination among all members of the squad. In less than two minutes, the last amphibian collapsed onto the stone floor, defeated by the impeccable synergy of our group.
Silence returned to floor 28, this time punctuated only by the girls' slightly accelerated breathing and the sound of water dripping from the walls. I sheathed my sword with a calm gesture, quickly inspecting everyone's condition to ensure that no serious injury had been overlooked in the heat of battle.
"Is anyone hurt?" I asked, carefully looking at each face around me with an expression of genuine concern.
"Just a few superficial scratches caused by the saltwater spray and the impact of the sand, nothing my quick potions can't solve in seconds," Elara replied with a reassuring smile, putting away her vials after checking Liriel's assistant's pulse, who had displayed admirable bravery throughout the confrontation.
"Excellent performance from everyone," I praised, feeling pride swell in my chest as I saw the efficiency with which we overcame the first true trial of that floor. "The ambush was well planned by the enemy, but our tactical discipline turned what would have been a disadvantage into an absolute victory. Let's continue advancing with the same attention until we find the safe zone where we can rest."
The girls nodded in perfect harmony, readjusting their equipment and recovering their strict formation. We continued crossing the stone bridges over the underground lake, aware that the victory over the amphibians was merely the prelude to the even greater dangers that awaited us in the depths of that aquatic sector. Every step we took reinforced the certainty that we were getting closer and closer to unraveling the final secrets kept by the Demon King.
