The solemn murmur that followed my declaration that I would accept the tower's challenge finally began to fade, giving way to practical and urgent movement within the council chamber. The King of Humans, visibly relieved that he would not have to send entire divisions of soldiers into an unknown vertical abyss, straightened his posture at the head of the oak table. He exchanged a quick glance with the commanding general of the border defenses, a veteran warrior with gray hair and deep battle scars across his face, and raised his right hand to officially establish the new chain of command before all the monarchs and representatives present.
"Given the unprecedented threat rising in the Isolated Lands, we hereby decree an immediate change to our front lines," announced the King of Humans in his firm, resonant voice. "Overall command of the allied troops and adventurers assigned to the Northern Front will be fully transferred to General Vane. He will assume responsibility for raising the defensive barriers and containing the advance of the demon legions along the rocky borders. Lord Takumi and his elite group are completely relieved of terrestrial infantry duties. Their sole, yet most crucial mission, will be the subjugation and exploration of the Demon King's Tower."
General Vane stepped forward, striking his armored fist against his chest in a respectful military salute. He knew that the fate of his surface troops would depend entirely on how quickly my group could weaken the influence of the dark sovereign from the top of that monumental spire. I thanked the general with a confident nod, formally ending my participation in that long strategic meeting. The board of the final war was set; while the Alliance fortified the ground, we would climb the skies.
We left the royal palace under the weight of a silent atmosphere, yet one charged with purpose. I walked back to our mansion accompanied closely by my companions, whose quick footsteps against the paving stones showed that they were already processing the dangers described by the Rank S adventurers. As we crossed the oak door of our residential pavilion, I closed it firmly and guided the group toward the large meeting table in the living room. Liriel, Elara, Lyannis, Rai'kanna, Vespera, Scarlet, and Liriel's assistant sat around me, focusing their attention entirely on me as I spread a blank scroll across the table to write down the fundamental points of our mission.
"The situation has changed drastically," I began, looking into each of their eyes with complete honesty. "The Demon King has raised a structure one hundred thousand meters high in the Isolated Lands that functions exactly like the progressive dungeon systems I used to face in my old world. He used my memories to create cruel rules: healing is suppressed by the tower's miasma, monsters revive stronger if we use excessive mana, and the biomes constantly change. But the Alliance has relieved me of command of the Northern Front so that we can focus solely on this tower. I have decided to accept this challenge, and I intend to enter it and decapitate him directly."
The silence in the room lasted only a brief moment before Elara stepped forward, adjusting the strap of her quiver with determination. "If this monstrosity was designed to test you, Takumi, then it was designed to test all of us. There is no possibility of us letting you climb that place alone." Scarlet struck the hilt of her sword against the floor, confirming her loyalty with a confident smile, while Liriel and her assistant had already begun discussing formulas for runic potions that could bypass the healing restriction imposed by the tower. Without hesitation, all of them confirmed that they would accompany me to the top.
With the group officially united under the same purpose, planning for the expedition began immediately. We knew that brute force would not be enough to overcome the one hundred thousand meters of runic challenges; survival would require mathematical precision, flawless coordination, and perfect logistical preparation. I looked at each determined face around me, feeling a deep sense of gratitude and the certainty that, regardless of the complexity of the rules created by the Demon King, we possessed the strength necessary to rewrite the ending of that story.
