The spatial manipulation required for sustained flight was more demanding than Su Chen had anticipated. Treating distance as negotiable and gravity as optional required constant Formation Arrangement expenditure—not crippling, but enough that he couldn't maintain this indefinitely while also fighting.
"Master, you're burning through energy reserves at thirteen percent per minute," Babata warned. "At this rate, you have approximately seven minutes of flight capability before spatial manipulation becomes unsustainable."
"Then we reach that helicarrier in less than seven minutes," Su Chen replied, accelerating toward the ascending platform. Saeko and Esdeath kept pace, their own capabilities allowing flight through different mechanisms—Saeko's Supreme Sword Bone generating spatial platforms she could leap between, Esdeath creating ice constructs that she used as stepping stones toward their target.
The helicarrier's automated defense systems detected their approach immediately. Weapons turrets swiveled, tracking systems locked on, and anti-aircraft fire erupted in patterns designed to saturate the airspace with lethal ordinance.
"Evasive maneuvers!" Su Chen commanded, his enhanced perception allowing him to see the projectiles' trajectories and adjust his flight path accordingly. Bullets and missiles streaked past, some coming within meters of impact, but his spatial awareness kept him ahead of the targeting solutions.
Saeko and Esdeath were equally effective at evasion—Saeko's sword intent cut through several missiles before they could detonate, while Esdeath flash-froze others in mid-flight, rendering their propulsion systems inert.
They reached the helicarrier's hull and landed on its upper surface, immediately taking cover behind structural elements as more weapons systems activated. The platform's surface was a maze of launch bays, weapon emplacements, and sensor arrays—all of it defended by automated systems and the Hydra operatives who'd seized control.
"Control center is three hundred meters forward and two decks down," Su Chen identified, his Dual Pupils perceiving the helicarrier's internal structure. "We need to—"
An explosion rocked the platform as something struck from below. Su Chen's silver pupil immediately identified the source—another helicarrier, Helicarrier Two, had apparently not been as secured as reported. It had launched missiles at Three, attempting to disable its sister platform through direct attack.
"This is Helicarrier Two command," a voice came through the communication network—not one of the S.H.I.E.L.D. teams, but clearly Hydra. "All loyalists are authorized to engage traitors on sight. Hail Hydra!"
"Damn it," Su Chen cursed. "Hydra controls Helicarrier Two as well. The report of it being secured was false—probably agents who were compromised through the Mind Stone's residual influence or Hydra loyalists who infiltrated the assault teams."
"Master, this situation is deteriorating rapidly," Babata stated with unusual alarm. "Both operational helicarriers are now under Hydra control. They're ascending to targeting altitude and their weapons systems are forty-seven seconds from achieving lock-on capability. When that happens, they'll begin eliminating the twenty-three million individuals on their target list."
"Can Director Fury order conventional military to shoot them down?" Su Chen demanded.
"He's trying, but the World Security Council is blocking authorization," Babata replied. "They're demanding stand-down, claiming the operation is unauthorized and constitutes a military coup. Politics is preventing tactical response."
"Of course it is," Su Chen said grimly. Politics always complicated crisis response when officials prioritized authority over effectiveness. "Then we handle this ourselves. New plan—we split up. Saeko, you take Helicarrier Two. Esdeath, you're with me on Three. We reach the control centers simultaneously and shut down both platforms before targeting activates."
"That's suicide squared," Saeko observed. "We'll each be fighting through hundreds of Hydra operatives alone."
"You've fought through worse odds," Su Chen countered. "And we don't have alternatives. Those platforms activate targeting in—" he checked the countdown Babata was displaying through his neural link, "—thirty-nine seconds. Move!"
Saeko didn't argue further. She simply launched herself toward Helicarrier Two, her Supreme Sword Bone allowing impossible leaps across the open space between platforms. Su Chen watched her land and immediately engage the defensive systems, her invisible cutting edges carving through automated weapons with surgical precision.
"She's terrifyingly competent," Esdeath observed.
"So are you," Su Chen replied. "Now let's prove it."
They descended into Helicarrier Three's interior through a damaged hatch, finding themselves in corridors that mixed S.H.I.E.L.D.'s utilitarian design with Hydra's modifications. Red emergency lighting cast everything in blood-colored shadows, and the air carried the acrid smell of weapons discharge and ozone from energy systems operating beyond safe parameters.
"Contact!" Esdeath warned, and Su Chen saw them—a dozen Hydra operatives in combat armor, weapons raised and clearly prepared for exactly this intrusion.
The engagement was immediate and brutal. Energy weapons designed to fight enhanced threats discharged at point-blank range, their beams converging on Su Chen's position. His Indestructible Diamond Body absorbed the attacks without effect, the conceptual defense treating reality-warping energy the same way it treated bullets—as fundamentally incapable of affecting his existence.
Esdeath's response was more direct. Her Frost Crown blazed with power as she dropped the temperature in the corridor by sixty degrees in under two seconds. The Hydra operatives' armor, designed to protect against energy weapons and kinetic impacts, provided no defense against absolute cold that bypassed conventional thermodynamics.
They froze where they stood, their biological systems shutting down as molecular motion stopped. Esdeath had been restraining herself for months, carefully concealing the true extent of her capabilities. Now, with time critical and stakes existential, she demonstrated why she'd been feared across multiple dimensions.
"Clear," she stated calmly, stepping over frozen bodies as if they were minor obstacles rather than human casualties.
They advanced through the helicarrier's corridors, encountering resistance at every junction. Hydra had clearly prepared for exactly this scenario—defense in depth, with operatives positioned to delay and attrit any assault force attempting to reach critical systems.
"Master, twenty-three seconds until targeting activation," Babata warned. "You need to reach the control center immediately."
"Working on it," Su Chen replied tersely, using his Formation Arrangement cultivation to inscribe spatial formations that created temporary portals through bulkheads. Instead of fighting through each defended checkpoint, he was bypassing them entirely, appearing in locations the defenders hadn't anticipated.
They emerged directly into the control center—a circular chamber filled with holographic displays and control stations, staffed by perhaps thirty technicians and guarded by twice that number of armed operatives. Every weapon in the room swiveled toward Su Chen and Esdeath the moment they materialized.
"Disable the targeting systems!" Su Chen commanded, his voice carrying authority that made several technicians hesitate despite their Hydra indoctrination.
"Never!" The response came from a figure Su Chen recognized—Baron Wolfgang von Strucker, one of Hydra's senior leadership, standing at the central control station with his hand hovering over what was clearly the final activation switch.
"The age of chaos ends today," Strucker declared with zealot's certainty. "Hydra's vision will be realized through Insight's cleansing fire. All who oppose order will be eliminated, and from the ashes will rise a world unified under our guidance!"
He pressed the activation switch.
For a moment, nothing happened. Then the helicarrier's entire structure shuddered as massive weapons arrays deployed from concealed bays. Targeting systems achieved lock, analysis algorithms identified priority targets, and across the globe, twenty-three million individuals who'd been designated as threats to Hydra's vision suddenly had orbital weapons tracking their locations.
"Targeting active," Strucker announced with triumph. "Weapons free in five... four... three..."
Su Chen moved faster than human perception could track. His hand caught Strucker's wrist before the countdown completed, and his Indestructible Diamond Body's absolute nature made resisting impossible—Strucker's enhanced physiology meant nothing against conceptual superiority.
"Shut it down," Su Chen commanded coldly. "Or I'll break every bone in your body until you comply."
"You can't stop Insight," Strucker gasped, his other hand moving toward a hidden device. "Even if you disable Three, Helicarrier Two will complete the mission. Hydra's vision is—"
Esdeath's ice spike pierced through Strucker's shoulder, pinning him to the control station and preventing whatever contingency he'd been attempting to activate. The Baron screamed, his zealot's composure cracking under the sudden injury.
"The man said shut it down," Esdeath stated with chilling calm. "I can make this hurt considerably worse if you need additional motivation."
"I... can't," Strucker admitted through gritted teeth. "The system requires three authorization codes to activate. Once activated, it requires unanimous consensus of the World Security Council to stand down. I don't have that authority. No one on this platform does."
"Then we destroy the platform entirely," Su Chen decided, already moving toward the central power systems. "Babata, identify the helicarrier's core reactor. I'm going to overload it."
"Master, that will cause the platform to fall from current altitude," Babata warned. "Impact casualties could be significant depending on where it lands."
"Less significant than twenty-three million people being assassinated from orbit," Su Chen replied coldly. "Calculate trajectory—where does this helicarrier impact if I overload its reactor now?"
"Processing... impact zone would be the Potomac River, approximately one mile south of the Triskelion. Structural damage to surrounding areas, but minimal direct casualties if civilian evacuation proceeds immediately."
"Director Fury, evacuate all personnel from the Triskelion and surrounding district," Su Chen transmitted. "Helicarrier Three is coming down hard in approximately four minutes. Get everyone clear."
"Understood," Fury replied without hesitation. "What about you and your team?"
"We'll manage," Su Chen stated, already moving toward the reactor compartment. "Just make sure you've cleared civilians from the impact zone."
The path to the reactor was more heavily defended—Hydra's operatives recognized what Su Chen was attempting and threw everything they had at preventing him from reaching the helicarrier's power core. Energy weapons, kinetic ordinance, and even improvised explosives filled the corridors with lethal force.
Su Chen ignored it all. His Indestructible Diamond Body made him effectively immune to conventional attacks, and his Formation Arrangement cultivation allowed him to inscribe protective barriers that shielded Esdeath from the few weapons that might have threatened her.
They reached the reactor chamber to find it was a marvel of engineering—a fusion core that generated enough power to keep a platform this massive airborne indefinitely. It was also heavily shielded and protected by multiple redundant safety systems designed to prevent exactly the kind of overload Su Chen was planning.
"Babata, I need to bypass these safety systems and force the reactor into catastrophic overload," Su Chen stated. "How long?"
"Normally? Approximately twenty minutes of careful system manipulation," Babata replied. "But if you're willing to accept crude methods, you could physically breach the containment and let physics handle the rest. Warning: that approach will result in immediate reactor destabilization with approximately ninety seconds before critical failure."
"Ninety seconds to evacuate a helicarrier," Su Chen calculated. "That's not enough time."
"It's enough time for us," Esdeath observed. "Everyone else on this platform made their choice when they joined Hydra. We warned them, we offered alternatives, and they chose loyalty to a Nazi conspiracy over basic human decency. I'm not losing sleep over their deaths."
Su Chen considered the ethics of condemning potentially hundreds of Hydra operatives to death through reactor overload. Some were true believers who'd chosen this path knowingly. Others were compromised through the Mind Stone's influence or recruited through deception. Killing them all without discrimination violated principles he'd tried to maintain.
But the alternative was allowing Project Insight to assassinate twenty-three million people worldwide.
"Do it," Su Chen decided. "Breaching reactor containment now."
His Supreme Sword Bone generated a cutting edge that existed across multiple dimensional layers simultaneously. He brought it down on the reactor's containment vessel, and the cutting intent carved through alloys designed to contain fusion temperatures and radiation.
The reactor's failsafes immediately activated, attempting to shut down the fusion reaction before breach could cause catastrophic failure. But Su Chen's cut had been too precise, too complete—the containment couldn't hold, and the fusion plasma began expanding explosively as pressure equalization failed.
"Reactor critical," automated warnings blared throughout the helicarrier. "All personnel evacuate immediately. Catastrophic failure in eighty-seven seconds."
"Time to leave," Su Chen stated, already inscribing spatial formations that would allow them to teleport off the platform. "Esdeath, on me. We're—"
"Wait," Esdeath interrupted, looking at something on the control displays. "Master, look at Helicarrier Two."
Su Chen's attention shifted to the external cameras showing Two's position. What he saw made his tactical assessment shift immediately.
Saeko had reached Two's control center. He could see her through the platform's internal cameras—a lone warrior surrounded by dozens of Hydra operatives, fighting with impossible speed and precision. Her Supreme Sword Bone carved through opposition with efficiency that made it look effortless, but Su Chen's enhanced perception could detect the strain. She was burning through energy reserves rapidly, and there were simply too many enemies.
"She's going to be overwhelmed," Su Chen stated, already abandoning his planned evacuation. "We can't leave her to face that alone."
"Master, Helicarrier Three will explode in seventy-one seconds," Babata warned. "If you don't evacuate now, you'll be caught in the blast."
"Then I'd better work quickly," Su Chen replied, his spatial manipulation flaring as he prepared to do something he'd never attempted before—teleport between two separate moving platforms while they were both experiencing combat damage and reactor instability.
The spatial formations he inscribed were complex beyond anything he'd done previously—calculations that treated three-dimensional space as mere suggestion, that compensated for the platforms' relative motion, and that punched through the defensive systems that should have prevented external teleportation.
"This is going to hurt," Su Chen warned Esdeath.
"Everything worthwhile hurts," she replied, gripping his arm.
The teleportation executed with violent force that felt like reality rejecting their presence. For a moment, Su Chen existed in a space between locations—perceiving both platforms simultaneously, feeling the dimensional stress as his consciousness tried to maintain coherence across impossible geometry.
Then they materialized on Helicarrier Two's control center, directly beside Saeko, who was surrounded by so many Hydra operatives that the chamber floor was barely visible beneath bodies.
"Su Chen," Saeko greeted without breaking her combat rhythm, her blade carving through another opponent. "I was beginning to think you'd forgotten about me."
"Never," Su Chen replied, his Formation Arrangement cultivation blazing to life as he inscribed containment formations around the entire control center. The Hydra operatives found themselves trapped inside barriers that treated their physical forms as completely confined regardless of their attempts to escape.
"Helicarrier Three?" Saeko inquired.
"Exploding in approximately forty-nine seconds," Su Chen confirmed. "Which gives us forty-nine seconds to disable Two's targeting systems, evacuate, and ensure we're not caught in Three's blast radius when it detonates."
"That's ambitious even by your standards," Saeko observed.
"Then we'd better move quickly," Su Chen stated, already advancing toward the central control station.
The next forty-five seconds were the most intense of his time in this universe—simultaneously disabling targeting systems, fighting through last-ditch Hydra resistance, and coordinating evacuation while a nearby helicarrier's reactor approached catastrophic failure.
But they succeeded.
With three seconds remaining, the spatial formations completed, pulling Su Chen, Saeko, and Esdeath off Helicarrier Two just as Three's reactor achieved critical mass.
The explosion was spectacular—a miniature sun blossoming at altitude as the fusion reactor's containment failed completely. The shockwave struck Helicarrier Two, crippling its flight systems and sending the platform into an uncontrolled descent toward the Potomac.
Both helicarriers fell from the sky, their weapons forever silenced, their targeting systems destroyed, and Hydra's ultimate weapon reduced to burning wreckage that crashed into the river with impacts that shook the surrounding city.
Project Insight was over.
And the purge had succeeded.
