Both start in hell: but their talents are multiplied a hundredfold.

The moment the first Chitauri aircraft burst out of the portal, the air was torn apart by its bio-engine with a sharp whistling sound.

The thing was covered in a grayish-black biological carapace, the surface of which was covered with pulsating purple blood vessels, through which flowed some kind of luminous liquid, like the exposed nervous system of a living creature.

The segmental thrusters on both sides of the aircraft emitted dark green plasma trails, corroding the air in their path and turning it into a pungent ozone smell.

Immediately afterwards, dozens of Chitauri aircraft emerged from the cave entrance, forming a loose column, like a swarm of metal locusts pouring out of the abyss.

Each aircraft carried a quadruped infantry drop pod on its belly, the surface of which was covered with the same biological carapace as the aircraft, with a viscous black liquid constantly seeping from the gaps.

Then the Chitauri bio-warships squeezed out of the portal.

Those warships were enormous, resembling crustaceans from the deep sea, with their hulls covered in eye-shaped sensory organs.

Each warship was over fifty meters long, and as they squeezed out of the opening, the force field at the edge of the opening emitted a piercing friction sound.

After the first warship completely broke out of the portal, it attempted to accelerate towards the northern airspace, but crashed into an invisible wall the instant it broke out.

The moment the head of the biological warship touched it, the entire warship began to shatter from the point of impact.

The disintegration of the warship triggered a chain reaction. The energy core stored inside it shattered and released a dark purple fireball. The fireball expanded for less than a millisecond before suddenly collapsing inward, compressing the Zeta Swiss soldiers inside the warship into a dense wreckage less than a meter in diameter.

The debris hovered in the air for half a second before falling vertically like a stone that had lost its support.

The second warship rushed out immediately, attempting to veer away from the invisible wall, but the force field enveloped the space from all sides.

This biological warship was doomed to destruction.

It shattered, collapsed, and then the debris fell.

More bio-warships burst out of the portal, crashing one after another into the invisible force field. Explosive fireballs burst forth in the narrow space hundreds of meters above Stark Tower, like a string of lit firecrackers.

The aircraft that had already entered New York airspace tried to turn back, only to find that the exit of the portal had been blocked by the continuous influx of warships. They could only hover over Manhattan like a swarm of bees that could not find their nest.

Tony hovered outside the force field, his mouth slightly open beneath his mask.

He watched as the Chitauri warships crashed into piles of collapsed wreckage overhead, as if trying to understand what had happened.

"Jarvis," Tony's voice was slightly unsteady.

"gentlemen?"

"That force field...is it on our side?"

"Based on my analysis, sir, the frequency characteristics of that force field are not consistent with the energy frequency of the portal."

"It comes from a separate source, and it appears to only work within a few hundred meters of the Stark Tower."

Tony was silent for two seconds.

"So someone held an umbrella over our heads."

"To be precise, sir, this umbrella is two-way barrier."

"It's just that we were a bit too rough with the creatures that came out of the portal."

Tony watched the warships crammed at the portal exit, unable to move, colliding and squeezing against each other because they could neither move forward nor backward.

He made a sound.

"what?"

That voice contained so much: confusion, absurdity, relief at surviving a catastrophe, and a deep sense of humiliation at having one's dignity as a scientist offended.

In the aircraft carrier's command center, Fury stood in front of the holographic screen, looking at the image above Stark Tower, and blinked his one eye.

He grabbed the communicator, his voice urgent.

"Can anyone tell me what that force field is?!"

There was a three-second silence on the communicator.

Then Shen Jue's voice came through the channel in the deep isolation chamber: "I guess it's a kind person passing by."

On the streets of New York, people looked up at the dark purple fireball that kept blooming above Stark Tower, their expressions shifting from confusion to pure terror.

Some people started running, some started screaming, and some stood still, as if nailed to the sidewalk.

Sirens blared from all directions as NYPD patrol cars sped through the streets of Manhattan, officers charging out with guns drawn before the doors were even fully open.

National Guard armored vehicles rolled across the Brooklyn Bridge, their tracks leaving deep marks on the asphalt, and the machine gun turrets on the roofs were disarmed.

"Attention all units, this is the emergency command center. An unidentified hostile force has appeared over Stark Tower. All ground forces are to assemble in Midtown Manhattan."

"Received, advancing towards the target area."

"Wait! Wait! There's an invisible wall in the road ahead! Repeat, an invisible wall!"

The moment the first armored vehicle hit the force field, its front end was completely crushed, and the driver inside was thrown forward by inertia, his helmet cracking against the bulletproof glass.

The convoy behind braked suddenly, their tires leaving four black rubber tracks on the road.

The police officers jumped out of the car and ran forward on foot. They ran less than twenty meters before crashing into the invisible barrier, which bounced them back and made them fall to the ground.

The force field is slowly expanding, from hundreds of meters above Stark Tower to a diameter of one kilometer.

Until it reaches nearly ten kilometers.

Every creature that enters this area, whether human, dog, or bird in a cage on a street corner, finds itself unable to move further in.

"What is this thing!" A policeman punched the inner wall of the force field, but his fist bounced back and the force field did not react.

"I don't know! But I can't move!"

"Me too! Is this some kind of cruel joke from God?!"

Panic spread through the population like a plague.

But at that moment, something even stranger happened.

All the citizens standing within the force field, including the police and soldiers, felt a lightness under their feet.

Their bodies left the ground, as if supported by an invisible hand, and began to drift out of the force field.

"What's going on? I'm flying?!"

"Oh! Damn it! Am I hallucinating from inhaling these leaves?"

Tens of thousands of people floated in mid-air at the same time, like dandelion seeds scattered by the wind, moving outward along the radial direction of the force field.

The boundaries of the force field automatically expand outward as they approach, making way for them, and then close again after they have passed through.

Shen Jue stood in the deep isolation chamber of the space carrier, her hands tucked into her sleeves, her eyes slightly closed.

His consciousness covered the entire Midtown Manhattan, and countless lives were orderly transferred out of the force field under the pull of the Phantom Breath Technique: Gravity Manipulation.

Within the force field's range, all life belonging to Earth was removed.

People were flying, dogs were floating, cats were gliding, and even the rats in the basement were lifted out by gravity and thrown outside the force field.

The inside of the force field is now empty.

All that remained were buildings, streets, vehicles, and the Chitauri biological warships still huddled together overhead.

"Then it's time for this drama to begin," Shen Jue said in a low voice.

Frank Castle, a cigar dangling from his lips, walked in from the edge of the force field.

He was followed by a group of dozens of people.

Those faces were those of the people who had been captured during the raid on Shen Jue's laboratory.

But at this moment, they are no longer entirely human.

Leading the way was the mercenary leader, whose limbs and torso had been replaced with cyborg prosthetics.

In addition, six miniature armor-piercing projectile launchers are embedded in the finger joints, each with a range of over one kilometer.

Two optical sensor balls were inserted into his eye sockets, and red halos silently rotated at the position of his pupils, scanning every possible firing point in front of him.

Another mercenary stood beside him, his entire lower body transformed into a spider-like mechanical structure, with eight blade-like metal legs extending from the end of his spine.

His upper body still retained the outline of a human, but dense metallic patterns were faintly visible beneath his skin.

Further on, dozens of mercenaries formed a skirmish line, each of them transformed into a cyborg in a different form.

Some men had their arms replaced with six-barreled rotary cannons, with ammunition belts extending from ammunition boxes at their lower backs and wrapped around supports between their ribs.

Some people have their entire face replaced by a tactical mask, which is covered with fly-like compound eye-shaped optical lenses, providing 360-degree coverage without blind spots, and has radiating heat dissipation fins extending from the chin.

Others had their spines elongated, their bodies hunched over like metal mantises, with a bioreactor bulging on their backs, green liquid churning beneath a transparent shell, providing super-powerful output to their prosthetic bodies.

They carried guns and had swords at their waists.

The gun is a modular weapon that combines live ammunition and energy beams. The gun body is wrapped with heat-resistant braided tape, and a cyborg neural network direct-connection aiming assistance interface is installed at the muzzle.

Swords are high-frequency vibrating blades, with a plasma film almost invisible to the naked eye covering the edge of the blade, cutting through steel as easily as cutting butter.

In the center of this group, three figures who had undergone the most thorough transformation walked side by side.

Doctor Octopus's spine was completely exposed and replaced by a complex life-sustaining machine.

His six mechanical tentacles are no longer external equipment, but prosthetic structures that grow directly from the end of his spine, with titanium alloy segments covered with a layer of bionic muscles woven from carbon fiber.

The ends of the tentacles are embedded with a multi-functional toolkit, including a laser cutting head, an electromagnetic pulse transmitter, and a high-voltage electric shock probe.

His eyes were replaced with two miniature reactors, their sockets glowing with a ghostly blue light that made his entire face look like a machine in operation.

Dr. Curtis Connors's cyborgization took a completely different path: mechanization and bio-enhancement.

He gave himself reptilian scales and claws, biomechanical devices with the properties of high-strength shape-memory metal.

The abruptly appearing long tail was actually replaced by a segmented metal whip, each segment capable of releasing high-intensity energy rays instantly.

Kingpin Wilson Fisk is the only one who still looks human, but only in a way.

His size has not changed; he remains enormous.

But beneath his skin lies a composite armored skeleton capable of withstanding anti-materiel sniper rifle fire, with each bone replaced by a honeycomb titanium alloy structure.

His heart was replaced with a miniature nuclear fusion reactor, providing a continuous source of energy for his bionic composite mechanical body.

Bullseye Lester's spine and joints were completely replaced with ultra-high-strength memory metal, allowing him to perform throwing actions that exceed the limits of human joints from any angle and in any posture.

His eyes were replaced with ballistic computers, and numbers for wind speed, distance, and gravitational acceleration constantly jumped in his pupils.

Frank Castle walked at the front, the smoke from his cigars billowing in front of him.

There were no signs of cybernetics on his body, at least not on the surface.

Frank glanced back at the inhuman team behind him and exhaled a smoke ring.

"Father Shen Jue sent me a message."

"There are no living people inside the force field," he said in a low voice.

"So, hit me however you like."

"The first operation of the Blackwatch Security Brigade."

"I hope you will not disappoint Father Shen Jue."

"This is already a battlefield, so get back alive."

The force field that bound the Chitauri disappeared.

The Chitauri biological warships poured down from above Stark Tower like a swarm of wasps whose nest had been disturbed, scattering into the streets of New York.

A single-person flying vehicle swept across the glass curtain wall of a skyscraper, shattering the entire wall into a rain of fragments.

The biological warship swooped into Fifth Avenue, its belly drop pods opening at low altitude. Dozens of Chitauri infantrymen landed, their four legs creating spiderweb-like craters in the asphalt.

The energy guns began firing, dark red beams crisscrossing the streets, shattering fire hydrants into fragments, and melting streetlights into scalding rain.

The Chitauri's resonant hum echoed throughout the city, low and persistent.

They were reveling, but there were no humans for these Chitauri to kill.

Frank stood still and crushed the cigar under his shoe.

"Blackwatch." His voice wasn't loud, but every cyborg mercenary's optical sensors turned towards him simultaneously.

"Let's attack."
