The strongest astral army in Warhammer 40K

**The Boundary of the Unbreakable Defense Line: The Void Battlefield**

Guilliman stood on the bridge of the **"Magnum's Glory"**, where the entire star system was ablaze in a holographic projection before him.

- **Left-side star map**: The Zerg bio-fleet proliferates like cancerous tissue, with Leviathan-class motherships spewing spore torpedoes.

- **Right-side star map**: The orcish junk fleet rampages, firing haphazardly with crude "bang-bang cannons," even accidentally injuring its own kind.

- **Central Area**: The two sides were already locked in combat, with Zerg Devourers digging holes in the Orcish scrap metal warships, while Orks, wielding machetes, leaped into the chambers of the Zerg hive ships.

"By the Emperor..." Katosicarios's visor reflected the flash of the explosion. "They wiped out thirty percent of the enemy's forces on their own."

Guilliman's lips curled into a cold smile.

"All fleets, heed my command!" His voice, amplified by psionic energy, reverberated throughout the entire Imperial fleet. "Fire at will—show them what war is all about!"

**First wave of attacks**:

The Mechanicus Arkship's main guns fired in unison, blasting twelve Orc space fortresses into molten slag.

The **Salamander Legion**'s plasma bombardment network burned out a vacuum zone with a diameter of 100,000 kilometers at the densest point of the swarm.

The **Ultraman Strike Cruiser**'s massive gun array delivers precise, targeted kills—specifically targeting enemy ships already engaged in combat.

**Second Wave of Attacks**:

The **Super Angels** psionic assault craft pierced the battlefield like silver lightning; Winged Warriors boarded the Zerg mothership, detonating neural nodes from within.

The **Imperial Guard Drop Pods** crashed directly into the orc flagship, and the black-armored warriors cleaved the power core with their halberds.

Russell stood in front of the hatch of the Thunderhawk gunboat. The "Blood Drinker" entrenching tool sensed the killing intent of the battlefield, and the dark red patterns in the blood groove flickered as if breathing.

"Prepare to board." He glanced at Carleon beside him. "We'll clean up the mess."

This chaotic battle gave rise to countless absurd and cruel scenes:

- An orc warship parasitized by the Zerg is firing its cannons while spewing out live ammunition (actually undigested orc remains) from its barrels.

The Tyranitar had barely squeezed into the gaps in the armor of the Imperial cruiser when it was charred into a crisp by the high voltage of the Mechanicus's pre-programmed circuitry.

- A certain green-skinned tech enthusiast accidentally attached a Zerg bio-cannon to his leg, resulting in one shot blowing off half of his buttocks.

But the most shocking thing is—

"Massive energy reaction detected!" the sensor operator suddenly screamed. "The Zerg mothership is...devouring Orc space meteorites?!"

On the hologram, the tentacles of a Leviathan-class mothership are entangled in an orcish "junk asteroid," breaking it down and absorbing it. Even more terrifying, crude orcish graffiti begins to appear on the absorbed insectoid ship's hull...

"They're hybridizing." Guilliman's pupils contracted. "All fleet, focus fire on that mutated mothership!"

Three hours later, when the last dilapidated orc cruiser was vaporized by the main guns of the battleship "Emperor's Wrath," the entire star system finally returned to silence.

Amidst the floating wreckage, the Imperial fleet began recovering boarding troops. Russell's squad brought back disturbing samples—

"Orc genetic signature confirmed on the Zerg carapace." The mechanical tentacles of the Mechanicus Sage trembled. "This...this is a completely new form of contamination!"

Killieman frowned slightly and said, "We don't have time for this."

The fighting on the ground is now far more brutal than the fighting in space.

**Unbreakable Defense Core Starfield - Surface Battlefield**

The earth is wailing.

The orcs' blood mingled with the Zerg's acid, forming a corrosive swamp that devoured every fallen corpse. On the battlefield, the greenskins' roars and the Zerg's shrieks intertwined to create a deathly symphony.

- **Orc side**:

The warlords, wielding their swords, led wave after wave of orc lads in relentless charges.

The massive orc used its thick armor to fend off the insectoid claws, but its carapace was already riddled with cracks.

The Orc Mastermind's tattered mech was overwhelmed by the swarm of insects, and the bomb he detonated before dying blasted away Tyranid creatures within a hundred-meter radius.

- **Zerg aspect**:

**Like a tidal wave of domineering blade worms,** they reaped orcs like the Grim Reaper, each swing of their scythes slicing through several greenskins.

A barrage of biological cannon fire from countless overlord-level gun bugs blasted the orc warband into a bloody mist.

A colossal Insectoid appeared in the sky above the battlefield, unleashing a torrent of psionic lightning that vaporized thousands upon thousands of orcs with each strike.

"They can't hold on any longer." Russell stood on the high ground, scanning the battlefield through his tactical goggles. The orc lines were crumbling; although they continued their frantic charge, the sheer number and quality of the Zerg had completely overwhelmed them.

Guilliman's holographic image appeared during the tactical meeting; his voice was calm and firm.

"The core cerebrate of the Hive's will is in the center of the battlefield." A massive psionic vortex marked the cerebrate's location on the star map. "Its psionic attacks are disrupting warp travel; we must destroy it."

**Tactical Deployment:**

**Orbital Bombardment:** The Salamander Chapter is responsible for clearing the outer swarms to create a passage for ground troops.

**Boarding Raid:** The Super Angels and the Imperial Guards form a decapitation squad, heading straight for the Brain Worm.

**Ground Advancement:** The Ultramarines and the main Astral Army launch a frontal assault to draw the Zerg's attention.

"Remember—" Guilliman's gaze swept over each commander, "This is not a battle, but an extermination operation. Leave no living thing."

Russell, Carleon, and the Black Armored Guard **Valdos** led an elite squad to infiltrate the battlefield.

They traversed the gaps in the battle between the orcs and the Zerg, avoided the ravaged areas of the psionic storm, and finally arrived at the **Flesh Tower** where the cerebrates resided.

It was a terrifying structure built from Zerg biomass, with the cerebrate hovering at the top and its psionic tentacles spreading across the entire battlefield like blood vessels.

"Go!"

- **Super Angel** spreads its wings, and its psionic spear pierces the brain worm's defensive barrier.

The **Imperial Guard**'s Blackstone Halberds tore through the Zerg's psionic network.

Russell's "Bloodthirsty" entrenching tool directly targets the core ganglion of the brain worm.

The cerebrate emitted a piercing shriek, and a psionic shockwave shattered the ground within a kilometer radius. But it was too late—

**"For the Emperor!"** Russell's entrenching tool pierced the brain worm's compound eye, and golden psionic energy poured in like a torrent, blasting it to pieces from the inside.

The death of the cerebrate plunged the Zerg into a brief period of chaos.

The remnants of the orcs seized the opportunity and launched their final **WAAAGH!!!** charge, their swords and iron fists tearing a gap in the swarm of insects.

But the empire's gunfire did not cease.

- **Orbital bombardment** reduced the Zerg's main force to ashes.

Ground forces clear out the remaining Terran creatures.

- **The Mechanicus Purifier** sprays chemical flames, burning away every inch of Zerg contamination.
