Kazahana Dōtō held a blazing Hexagonal Crystal in his hand, while the Rainbow Ice Wall behind him roared as if an ancient behemoth had awakened.
His eyes burned with a mad, determined arrogance as he held the crystal high, as if raising a scepter.
"You troublesome rats, witness this in your despair!"
He laughed wildly, pouring all his immense Chakra into the crystal. The crystal's light surged, transforming into a towering, azure pillar of light that crashed into the very center of the ice wall!
"Crack--Boom!!!"
The ice wall trembled violently, and a huge, irregular crack appeared in the center. A dazzling and strange light, a mixture of orange-red and azure, surged out of the crack, carrying with it an indescribable, calming, and warm current.
Kazahana Dōtō's face lit up with ecstasy. He couldn't wait and was the first to rush into the rift of light.
Nadare Rōga and Fuyukuma Mizore followed closely behind, loyally guarding both sides of the entrance, vigilantly watching Kakashi, Shira, and the others outside.
The people from Konoha and Sunagakure immediately tried to rush forward to stop them, but were temporarily blocked by the Nadare Rōga Avalanche and the thick ice walls summoned by Fuyukuma Mizore.
Kakashi's Lightning Blade sliced a gash in the ice wall, and Shira's longsword pierced it as well, but that brief delay...
From within the crack came a distorted Kazahana Dōtō, first of utter astonishment, then transforming into utter fury:
"What is this?! No--!! Impossible! This can't be real!!!"
That voice was filled with the madness of shattered dreams.
Kakashi and Shira exchanged a glance, then exerted their strength simultaneously, shattering the ice wall and leading everyone into the crevice.
The scene inside stunned everyone.
The interior of the ice wall is an extremely vast, high natural dome.
At the center of the dome, there is not some world-destroying weapon or an inexhaustible source of energy, but a massive, precise, and indescribably complex mechanical construct.
Countless gears, pipes, glowing crystal conduits, and ancient runes intertwine to form a whole that is full of geometric beauty and engineering ingenuity.
At this moment, activated by the Hexagonal Crystal, the giant machine is running smoothly, emitting a deep and reassuring hum.
At the core of the machine, a continuous, warm, and soft orange-red light emanated.
Most shockingly, as the machines were running, the ancient ice on the walls and top of the dome was melting at a visible rate!
Clear snowmelt flowed gently down the pre-set grooves and pipes of the machine, into the ground, and through countless branches, flowed into the depths of the ice walls, into all directions of the Land of Snow, invisible to the naked eye.
The warm air currents became increasingly noticeable, dispelling the bitter cold that had accumulated within the cave for thousands of years.
This is not an armory, nor a source of power.
This is a geothermal generator. A magnificent heating system capable of changing the climate of the entire Land of Snow.
It is the result of all the hard work and dedication put into the Kazahana Sōsetsu that this frozen land has left behind a true "treasure"—a spring that can be looked forward to.
"Aaaaaah--!!!"
Kazahana Dōtō went completely mad. He stood in front of the roaring machines, looking at the scene before him that ran counter to his life's pursuit, looking at the light that symbolized warmth, and felt that all his scheming, killing, and ambition over the years had become a huge joke!
Like a wounded beast, he frantically attacked the surrounding machine parts, his Ice Release Ninjutsu bombarding them wildly, sending ice shards flying, but only leaving shallow marks on those exceptionally sturdy components.
"Liar! Coward! You and your daughter are both cowards! The Land of Snow doesn't need warmth! It only needs power! Absolute power!!"
Utter disappointment transformed into a furious rage that consumed all reason. He abruptly turned his head, his crimson eyes fixed on Kazahana Koyuki.
"It's you! It's all because of you!! It's ruined! Everything's ruined!"
The Chakra Armor on Kazahana Dōtō's body emitted a dangerous overload shriek due to the intense emotional fluctuations and excessive Chakra output of its master. The blue and white light flickered violently and was extremely unstable.
He completely abandoned all thought, carrying overloaded armor and rampaging Ice Release Chakra, like an out-of-control iceberg, crashing into Koyuki with a mad, suicidal madness!
"Protect the princess!" Kakashi and Shira shouted simultaneously, rushing forward to meet her.
But at this moment, the power, speed, and defense of the Kazahana Dōtō were pushed to the limit by the berserk state of the Chakra Armor. With a brute force, it actually managed to smash through Kakashi's side Lightning Blade and the Shira blade that was thrusting towards it from the front!
The two were so shaken that their arms went numb, and they staggered to either side.
Nadare Rōga and Fuyukuma Mizore roared and pounced, tightly binding Sasuke, Shūji, Maki, Ishikawa, and the others who were trying to come to their rescue.
Sakura and Naruto's Shadow Clone desperately protected the panicked Koyuki and Sandayu as they retreated.
"Get out of here!!"
With a single punch, Feng Hua Nu Tao sent several Naruto shadow clones flying. The icy wind from the punch grazed Xiao Xue's cheek, leaving a bloody mark.
In his eyes, there was only the Kazahana Koyuki, symbols that bore witness to all his failures and humiliations.
"You're not allowed to touch Sister Koyuki!!" Naruto charged in from the side, his Chakra boiling, and the azure Rasengan in his right hand rapidly spun into shape. With his unstoppable roar, he slammed it hard into Kazahana Dōtō's side!
"You're courting death!" Before Kazahana Dōtō had even fully turned around, his overloaded armor flashed with blue light, and his left arm swung back fiercely, colliding violently with the Rasengan!
boom!
The shockwave exploded! Naruto screamed as his Rasengan instantly dissipated. He was sent flying backward by the immense force, crashing heavily into the base of a massive gear-like device behind him. He coughed up a mouthful of blood, and the Hexagonal Crystal in his hand flew out, landing with a clatter on the ground a short distance away, still emitting a soft glow.
" Naruto!" Koyuki burst into tears.
"You're next!" Kazahana Dōtō didn't even glance at Naruto, his bloodshot eyes fixed on Koyuki as he approached step by step.
Naruto struggled to get up, but felt as if all his bones were falling apart and his Chakra was in complete disarray.
He watched the approaching Dotō, watched the weeping Koyuki, watched the warm, glowing crystal that had fallen to the ground, and felt the increasingly dense warm air currents emanating from the geothermal generator...
That warmth was unlike any Chakra he usually felt. It wasn't scorching or violent; it was like the first ray of sunlight after winter, gently and firmly melting the ice.
For some reason, he remembered the Ichiraku Ramen that Iruka-sensei had treated him to, the hot springs he had soaked in with Jiraiya during their training, and the smiles of his companions...
A vague, warm feeling, mixed with a strong determination to protect Kazahana Koyuki, surged within him.
Almost unconsciously, he struggled to raise his right hand again. The remaining Chakra within his body, following his most instinctive impulse, began to swirl and coalesce.
This time, it was no longer just a simple azure blue. The core of the Rasengan seemed to have absorbed a trace of the warm aura emanating from the geothermal generator flowing in the surrounding air, and it took on a faint, almost imperceptible orange-red halo.
This wasn't a change in attributes that he actively controlled. Rather, it was the warmth of the world and the melting power of nature that sensed the boy's pure heart of protection—the desire to "break through the winter and bring spring"—and spontaneously and gently flowed into his Rasengan, a symbol of "possibility."
Kazahana Dōtō's hand was about to grab Kazahana Koyuki's neck.
"Get away from her, you bastard!!!"
Naruto used his last bit of strength to leap up and slam the Rasengan, which had absorbed the warmth of the environment and turned a strange color, into Kazahana Dōtō's unsuspecting back—the very core area of his Overload Armor where the light was most unstable and cracks were beginning to appear!
Kazahana Dōtō sensed the approaching gale from behind, but his rage and contempt only allowed him to slightly turn to the side, concentrating the overloaded energy of his armor on his back to withstand the attack.
He believed that this final, desperate attack would not be able to break through his defenses.
However--
"Puff..."
A strange sound, like hot water being poured onto solid ice, rang out. There was no earth-shattering explosion.
Naruto's Rasengan, infused with a hint of warmth, did not clash violently with the extremely cold Overload Armor on Dotō's back upon contact; instead, it felt like a gentle erosion.
The overloaded ice-attribute Chakra encountered this warm power originating from geothermal energy and symbolizing spring, as if it had met its natural enemy.
The violent blue-white light on the armor, centered on the point where the Rasengan struck, quickly dimmed and extinguished, and the flickering runes shattered one after another like a burned-out circuit.
The armor itself emitted a mournful cry of unbearable strain, and the cracks instantly widened and spread.
"What...?!" Kazahana Dōtō stared wide-eyed in shock, feeling a completely different warm current that made his icy chakra tremble. It broke through his armor like a hot knife through butter and entered his meridians. Wherever it passed, his Chakra melted and disintegrated as rapidly as snow under the spring sun!
"No--! My power!!!"
He let out a shrill, desperate scream, as if struck by lightning. His forward momentum came to an abrupt halt, and the overloaded armor shattered completely, turning into countless dull fragments that peeled off his body.
He staggered a few steps, then coughed up a mouthful of blood and ice shards. His breath deflated like a punctured balloon, and he collapsed to the ground, curled up, his eyes filled with despair and confusion. He muttered unconsciously, "Impossible, warm spring, ha... heh..."
Almost at the same time that Naruto defeated Kazahana Dōtō, the battle on the other side was also nearing its end.
Kakashi's Sharingan of Nadare Rōga's momentary lapse in Lightning Blade due to his master's defeat. The light of his Lightning Blade surged, piercing through the gap in Wolf Fang Avalanche's swing at an even more cunning angle, precisely striking the connection between Wolf Fang Avalanche's shoulder blade and his armor, severely injuring him and causing him to fall to the ground.
Seeing that all was lost, Fuyukuma Mizore roared and tried to launch a final self-destruct attack, but was held back by Shira's sword light.
Without activating her powers, Shira relied solely on the extraordinary perception and exquisite swordsmanship brought by the Wind Xun Breathing Method. Her sword was as sharp as the wind, always striking the weak points where the Fuyukuma Armor could exert its power, leaving him with brute force but nowhere to use it.
In the end, Shūji and Maki worked together. Shūji used a powerful wind and fire combined Ninjutsu to break through Fuyukuma's defenses, and Maki's sealing talisman followed closely behind, firmly binding and sealing Chakra.
Inside the cave, the clamor of battle quickly subsided, leaving only the steady hum of the geothermal generator and the pleasant gurgling sound of melting ice and dripping snow.
The sunlight, seemingly breaking through the clouds, streamed down from the cracks in the ice walls and the melting ice cave ceiling above, intertwining with the warm light from the geothermal generator. It shone on the glistening melting ice and flowing water, refracting countless tiny yet magnificent rainbows.
The entire cave was warm and cozy, like springtime.
Naruto collapsed to the ground, utterly exhausted. He looked at his right hand, which was slightly smoking, and then at the motionless Kazahana Dōtō, his face blank, as if he hadn't fully grasped what had just happened.
Koyuki rushed over to support him, tears streaming down her face—tears of joy.
Kakashi walked over to Kazahana Dōtō, confirmed that he was completely incapacitated, then looked at the subdued Nadare Rōga and Fuyukuma Mizore, and nodded to Shira. These troublemakers were now resolved.
Shira sheathed her sword, walked to the Hexagonal Crystal lying quietly in the light and shadow, and bent down to pick it up. The crystal felt warm to the touch, and its light was restrained.
He walked up to Koyuki and handed the crystal back to her.
Koyuki took the machine with trembling hands, pressed it tightly to her chest, looked at the huge, roaring machine that brought warmth deep in the cave, then at her wounded but determined companions beside her, and finally, her gaze fell on her defeated uncle huddled in the distance.
After a long while, she wiped away her tears and straightened her back. For the first time, a clear and firm expression appeared on her beautiful face, which was always etched with fear and sorrow. It was the responsibility and awareness that belonged to a princess and a future leader.
The ice is melting.
The snow will eventually melt into spring water that nourishes the earth.
And hope has already begun to quietly flow across this land that has been frozen for too long...
