Chapter 257

Deep within the underground karst cave, Levi's temporary base had already taken initial shape.

After several hours of construction, the originally empty cavern had been transformed into a fully equipped command center.

Silver alloy walls divided this area into several independent functional zones.

Nanobots were still continuously refining the base's structural details.

In the main control room, Levi was leaning over, examining the rapidly flowing data streams on the console.

Large amounts of mineral survey results were updating in real time.

"Report." Max walked in quickly. "The North District's defense system has been fully deployed; the energy shield can be activated at any time."

"Continue scanning, focus on the deep underground layers." Levi answered without raising his head, fingers rapidly adjusting parameters on the control panel.

"The underground resources of this era are still very abundant; we must seize this opportunity."

The Naruto World's productivity is in an extremely backward state; underground resources have hardly been developed at all, which happens to benefit them right now.

"Boom!"

Suddenly, a violent tremor came, the entire karst cave trembling. Instruments on the console flashed wildly, emitting piercing alarm sounds.

"What's going on?" Adam immediately turned to look at the screen.

Levi walked quickly to the console, fingers rapidly tapping on the keyboard: "The energy detector has detected a strong electromagnetic fluctuation, its level far exceeding previous values."

"Rumble!"

Another tremor, this time even more violent than before. Gravel fell rustling from the cavern ceiling.

The values on the monitoring instrument climbed continuously, soon breaking through the maximum scale.

Levi quickly brought up the three-dimensional map. In the translucent holographic projection, a red energy cluster was expanding wildly, like ink dropped into clear water, quickly dyeing a large area red.

"This kind of energy fluctuation." Levi narrowed his eyes. "It's an electromagnetic pulse, and this frequency... Alan, he has used Bankai."

"Bankai?" Max's eyes widened. "The Captain's final release form?"

He had never seen the Captain use this ability before.

Levi nodded. "Didn't expect to encounter an opponent here who could force Alan to use Bankai." He pulled up more monitoring data. "This world's power level is indeed quite deep."

"Captain, should we go provide support?" Adam clenched his fist, black hair faintly surging beneath his skin.

Levi turned his head to glance at Adam, revealing a questioning expression, then shook his head and said: "No, the battle on his side has already exceeded the level at which we can intervene."

He pointed at the monitoring screen. "Look at the intensity of these energy fluctuations; they have already reached the degree of being able to tear space."

Max leaned closer to the screen: "But the Captain he"

"Alan has his own judgment." Levi said simply.

"What's most important for us right now is completing the base construction. Within two hours, the main framework must be finished. Let's go, check the progress on site."

The three left the command room and entered the underground karst cave; the scene before them made Max and Adam instantly hold their breath.

Countless silver nanobots flowed through the air like water; they split into dozens of main streams, each constructing different facilities.

The flowing silver rivers intertwined in the air, continuously splitting and recombining, forming a spectacular sight.

The main control center was already complete; military factories were rising from the ground one after another.

Tens of thousands of nanobots surged out from passages around the base, beginning rapid construction in the underground space.

"This is our main base." Levi pushed up his glasses.

Max and Adam stared wide-eyed, looking at the scene before them.

Suddenly Max pointed at one of the production lines: "Wait, that's the Siege Beast from StarCraft?"

"Good eye." Levi nodded. "But this is an upgraded version. The armor uses hybrid nano-materials; adaptive armor can adjust defense methods in real time according to attack type."

"Not just that." Adam looked at another production line. "Warhammer 40K's Ravager, Red Alert's Doomsday Tank... these are all top-tier armor."

"Every unit of armor is equipped with Mass Effect kinetic barriers," Levi explained, "and the Matrix Power Supply System from StarCraft."

Above the factories, large groups of Valkyrie Fighters were being assembled; silver fuselages gleamed with cold light under the lamps.

"These are mass-produced units from Titanfall?" Max looked up at those ferocious fighters.

"Improved versions." Levi pulled up data. "Integrated Macross transformation technology, allowing free switching between air combat and ground combat."

"That thing in the sky... isn't that the O'Neill Orbital Space Station?" Adam pointed at the massive space station being built above the base.

"Correct, the orbital space station from Cyberpunk, but its interior is loaded with Metal Gear's orbital ion cannon. One shot can vaporize a small mountain."

The two watched the continuously produced weapons, their expressions dazed.

The entire underground karst cave had been transformed into a giant military factory, and it was still expanding continuously.

"These are our trump cards?" Max was still in shock.

"These are only the beginning; in another five hours, production capacity will increase tenfold."

"But it's still not enough; we lack true top-tier power." Levi said at this moment. "We must find the Dragon Vein; we need more powerful strength."

"But it's still not enough." Levi walked to the main console, fingers quickly pulling up a series of data. "No matter how powerful these weapons are, they are only conventional military force. We lack true top-tier combat power."

"Launch reconnaissance satellites first." Levi pressed a button on his wrist.

"Initiate launch procedure."

A dull mechanical sound came from the ground; several cracks split open in the cavern ceiling.

A dozen launch shafts opened in sequence, revealing silver rocket launchers below.

"Boom!" Accompanied by deafening engine roar, the first rocket soared into the sky, orange-red tail flames illuminating the entire underground space.

"Launch shaft two ready!"

"Launch shaft three preparation complete!"

"Launch shaft four."

Rockets launched in succession; in the blink of an eye, dozens of satellites rushed toward the high sky.

Levi watched the monitoring screen, which displayed the real-time position and operational status of each satellite.

A few minutes later, the first batch of data returned, and Levi quickly scanned the scrolling information on the screen, his eyes suddenly lighting up.

A red marker popped up on the main screen; the energy detector displayed a massive fluctuation source.

"Found it!" Levi's eyes lit up. "The Dragon Vein's Location!"

Levi immediately pulled up the Three-dimensional Map; a distinct energy vein snaked and extended underground.

At This Moment, the main console suddenly emitted a sharp alarm sound.

"High-speed moving target discovered in the Northwest Direction!" Max shouted.

"Pull up the visual."

The main screen displayed a five-man squad; they were treading on treetops advancing rapidly, their speed shockingly fast.

Levi narrowed his eyes: "How far away?"

"At current speed, approximately five minutes until arrival."

"How is that possible?" Levi frowned tightly; the Base outside was shrouded in a layer of Camouflage Shield.

Logically speaking, outsiders absolutely could not discover the Base's Location.

"Never mind." Levi said Calmly, "Launch the defense system, full force mobilization, Max and Adam, come with me to the Dragon Vein's Location."
