As dawn broke, Tsubasa led several hundred elites from the Sealing Department, following behind Uzumaki Ashina, and surged onto the large open space next to the Hokage Building. From afar, they could see Asuka Nobumoto, the head of the Mechanical Scientific Research Department, leading several hundred people back and forth there, their toes almost grinding Mars into the ground.
"We've been waiting for you!" Asuka Nobumoto shouted in a loud voice, startling the sparrows in the trees into fluttering flight. " The Kage Academy is breaking ground today. There's nothing more important for Konoha than this!" He rubbed his hands together as he spoke, his eyes fixed on Tsubasa as if he were staring at a piece of gold that could conjure money.
Tsubasa didn't hesitate either. He stood in the center of the open space, his hands Hand Seals rapidly like twisting dough, forming hand seals. Finally, he slammed his palm onto the ground with a "smack." The open space immediately began to steam like boiling water. First, rocks and cement piled up and shot upwards, then large rock fragments connected together, like building blocks. In the blink of an eye, buildings sprang up like bamboo shoots after a rain. Sunlight shone on the buildings, making the runes on them flicker. The large plaque above the entrance, with its three gilded characters " Kage Academy," was so dazzling it was hard to open one's eyes. All the sealing talents and Scientific Research Department personnel exclaimed, "Every time we see the Lord Hokage build houses, it's like witnessing a miracle!"
The crowd looked at the Kage Academy, which consisted of more than twenty buildings, including male and female dormitories, a canteen, a library, teaching buildings, laboratory buildings for various majors, a martial arts training ground, an auditorium, and so on. The flowers, trees, pavilions, and beauty salons between the buildings made it seem like a fairyland.
After the buildings were completed, hundreds of Konoha's elite Sealing Jutsu and mechanics specialists entered the various buildings to assemble advanced equipment, install facilities, and inscribe runes. Asuka Nobumoto, looking at the "various teaching buildings" before him, pulled out a small notebook and muttered as he took notes, "The furnace temperature in the forging area needs further adjustment, and the stored medicinal herbs in the alchemy building should be labeled..."
Meanwhile, Tsubasa and Uzumaki Ashina Neko entered the technology building and took the rune elevator to a depth of more than two thousand meters underground. This was the secret room that Tsubasa had just built, and it would be the location of the Kage Academy's biggest secret.
Tsubasa drew several rune lamps with runes. The space was a spacious two-story area, about the size of a basketball court. Tsubasa created several Shadow Clone and had them decorate the entire underground space. Soon, the space was decorated like a luxurious scene from a science fiction movie. Tsubasa began taking out various assembly parts and assembling them into a huge metal platform. Each platform was engraved with magical runes, resembling a massive and ancient altar.
The most eye-catching thing was the fist-sized spacetime crystal, purple with a hint of gold, as if it contained a flowing galaxy. Tsubasa held the crystal like he was cradling a baby, gently placing it into the groove in the center of the platform. As soon as he let go, the entire platform suddenly hummed, and the surrounding electricity and the light of the runes made it impossible to open one's eyes.
Uzumaki Ashina subconsciously took half a step back, and saw dense runes appear on the surface of the platform, flowing down like rain, finally gathering in the very center into a rotating portal of time and space—a rotating black, devouring portal that swallowed everything like an abyss, even light disappeared inside.
"It's done?" Uzumaki Ashina's throat tightened, his voice sounding like he was being choked. Tsubasa didn't speak, but instead pressed his fingers into Hand Seals on a control panel about a meter in size beside the platform. With a loud "boom," the black hole on the metal platform suddenly rippled like water, revealing the pitch-black space inside. Uzumaki Ashina leaned closer and could vaguely see floating nebulae and twinkling points of light inside, as if the entire universe had been stuffed into it, countless times larger than the spacetime of the Land of Whirlpools.
"This thing... you actually managed to make it?" Uzumaki Ashina felt his throat go dry, reaching out to touch it but not daring to, his fingers trembling as they hovered in mid-air.
Tsubasa pulled a metal rune token from his pocket and handed it to Uzumaki Ashina, nodding, "This is the pass to enter and return to the space. Why don't you come in with me and take a look? I haven't been idle in the Shikkotsu Forest these past three years. I've been refining weapons, making medicine, and researching Sealing Jutsu. I have the entire Land of Fire as my logistics support, so I'm not short of materials at all. Over the years, I've thoroughly memorized the ' Setsuna Splendor ' space formula. Take this spacetime conversion, for example—" He tapped the control panel with his finger, "A year inside the space is only a day outside. Moreover, the spacetime is extremely stable. You can unleash attacks below the Sage Level inside without causing spacetime turbulence."
Uzumaki Ashina swallowed hard. "And how big is that space? It'll be so big you'll have trouble even turning around." Tsubasa grinned, revealing his back teeth. "10 million square kilometers, much larger than our entire Land of Fire. Forget turning around, it could hold a world war."
At this point, Tsubasa's eyes suddenly lit up, as if two lamps had been lit. "Think about it, when students at the Kage Academy spend a year studying, only a day has passed outside. A year inside yields hundreds of years' worth of knowledge and experience—if they still can't become a Super Kage Level powerhouse, they can only blame their poor talent. However, we select geniuses who are one in ten thousand. In ten years, our Konoha will have several thousand Super Kage Level powerhouses!"
He suddenly lowered his voice and said with a smile, "This will be the sacred ground of the entire Shinobi World. The spatial materials are too precious, so only one could be made. This is also the biggest secret of the entire Konoha. From now on, access to this place will be controlled by the three of us—me, you, and that girl Tian Yueqing. By the way, I plan to make you the principal of the Kage Academy, Yueqing as the vice principal. You have no objections, right?"
Uzumaki Ashina stared at the spinning portal, suddenly feeling a surge of heat in his eyes. He patted Tsubasa on the shoulder. "You kid... you truly are a peerless genius of the Shinobi World! Why don't I have that kind of brain?" He turned back to the dark portal, his Adam's apple bobbing, "Once this gets out, won't the nations of the Shinobi World be so envious that they start another world war? Our Konoha... is about to change."
Tsubasa sneered disdainfully, "Change of the world? This is nothing. Once the students of the Kage Academy have all grown up, I'll have no choice but to destroy any country that causes trouble." He suddenly laughed, "But seriously, by then, we might unify the Shinobi World without shedding a drop of blood?"
Uzumaki Ashina shook his head, feeling a surge of heat rising in his chest, as if he'd drunk ten pounds of strong liquor. Tsubasa pointed to the portal, a fierce glint in his eyes. "Let's go in and see what it's like inside."
The two walked into the portal with smiles on their faces. Their laughter disappeared on the platform, where the runes were still glowing white, as if providing special effects lighting for this "alternate dimension" that was capable of changing the rules of the Shinobi World.
