The silence that followed the conclusion of Cedric Thorne's report was different from all the others that had filled the council chamber until that moment. It was not merely a silence of hesitation or fear, but of deep and heavy tactical assimilation. The kings and veteran generals stared at the runic diagrams scattered across the oak table as if they were trying to decipher a language from another plane of existence. For them, indeed, that structure was a geometric and magical anomaly without any precedent in the military history of the continent. For me, however, the feeling was one of an almost painful familiarity.
The checkpoints every five floors, the adaptive rebirth of monsters based on the mana used against them, the systematic suppression of healing abilities to prevent the invader from relying on slow attrition, the artificial dimensions with progressively increasing difficulty. Every detail presented by Kaelen Vance and dissected by Cedric Thorne pointed toward a very specific concept that I knew perfectly from my previous life: a classic extreme-survival video game dungeon.
I leaned slightly back in my chair, feeling the heavy fabric of my cloak rub against the wood. My thoughts inevitably went back to the countless mental confrontations and dreamlike projections I had with the Demon King over the past few months. Those unwanted visits to the gray plane of the conceptual void had not merely been attempts to psychologically destabilize me or test my willpower. In fact, during those brief spiritual invasions, the sovereign of darkness had been probing the deepest and most dormant layers of my mind. He had accessed my memories of the virtual worlds I came from, extracting the structural principles, game mechanics, and systematic punishment rules that once served as entertainment in my old world, only to rebuild them in a real and lethal form on the physical plane of this continent.
"He did not build a fortress," I murmured quietly, although the sound of my own voice caused every head around the great table to instantly turn in my direction. "He built a tailor-made trial arena. A perfect simulation based on rules he stole from my own memories."
The Elven King frowned, his eyes narrowed and focused on my face with a mixture of intellectual curiosity and apprehension. "Lord Takumi, what do you mean by that? Your memories? How could the enemy sovereign possibly construct something of such magnitude based on your mind?"
"During our encounters in the dream plane," I explained calmly, keeping my voice firm to convey confidence to those present, "the Demon King searched for weaknesses in my mental barrier. He did not merely want to kill me from a distance; he wanted to understand what shaped the way I think and how I overcame each of his generals with tactics that no warrior in this world normally uses. He discovered that, in my homeland, we faced these same challenges in the form of fictional challenges structured progressively. He took that logic, fused it with his divine-level spatial magic, and brought it to the Isolated Lands to create the setting for our final confrontation."
Liriel placed her hand on my shoulder, her gentle touch bringing a comforting warmth that contrasted with the cold atmosphere of the chamber. "Does that mean you already know the basic workings of each challenge awaiting us inside, Takumi?"
"The general logic, yes, but the physical execution will be completely different and infinitely more dangerous than any fiction," I replied, looking at her and then at my other companions. "There is no health bar, there are no real automatic saves that will bring us back from the dead if we fail, and the monsters do not follow predictable artificial intelligence patterns. The danger there is real. If we die inside that tower, our existences will be permanently integrated into the energy core that sustains the structure, exactly as Kaelen Vance predicted when he retreated."
Liriel's assistant began taking quick notes on her small scroll, integrating my conclusions with the technical data Cedric had provided. Across the table, the Dwarven King slammed his sturdy fist against the oak, making the metal mugs vibrate. "If this monstrosity was designed based on your own experiences, then no one besides you and your group possesses the qualifications necessary to lead this invasion, boy! Sending infantry or cavalry armies into this runic meat grinder would be an unforgivable waste of precious lives needed for the physical war in the north."
The Human King agreed with a grave nod. "The Dwarven King's judgment is correct. If the demonic legions are actively marching toward our northern defensive lines, we will need every soldier, every Rank A warrior, and every elite battalion on the walls to contain the enemy's advance. If we fragment our defenses by sending entire legions to investigate a tower one hundred thousand meters high, we will be crushed on both battlefronts simultaneously."
I slowly rose from my chair, feeling the silence of the chamber concentrate entirely upon my figure. I partially drew my sword, allowing the sky-blue glow of the runic blade to subtly illuminate the map that separated our territory from that barren point in the Isolated Lands. The weight of leadership had never felt so real, but the determination I saw in the eyes of Elara, Scarlett, Rai'kanna, Lyannis, Vespera, and Liriel gave me certainty that the choice had already been made long before we entered that meeting chamber.
"I accept the challenge," I officially declared, looking directly at the sovereigns of the Alliance. "The Demon King built this tower as the ultimate test for my elite group, knowing that I would be drawn to it to prevent the massacre of the allied nations. We will enter that structure. We will unravel each of its biomes, disarm its traps, activate the spatial checkpoints that the researcher located, and carve our way surgically to the top. If the enemy wants to play by the rules of my old world, I will show him that I know the limits of this board better than anyone."
A murmur of solemn approval spread among the generals and the representatives of the dragons. The Human King let out a long sigh, which seemed to carry the temporary relief of knowing that the kingdom's main military force could concentrate entirely on the land battlefield. He extended his open hand toward me, in a gesture of mutual respect that was immediately followed by the other leaders around the circular table.
"May the gods accompany your steps in the darkness of that spire, Lord Takumi," said the human monarch. "While your squad climbs the skies to decapitate the enemy's leadership, we will ensure that the ground you left behind remains free of the demonic hordes. The United Nations Alliance will stand firm until your return or until the last warrior falls defending our walls."
I sheathed my blade with a sharp click that marked the end of the official meeting. The council began reorganizing itself for the practical developments of the mobilization of the land armies, but my thoughts were already far away, crossing the miles of desert that separated us from the Isolated Lands. The Demon King's final challenge had been formally proposed and accepted. Now, it was up to us to prepare for the incursion that would dictate the end of the war once and for all.
