The first to arrive was the Imperial Fleet's bombardment.
The first high-energy nuclear missile was dropped into the atmosphere of the Sautekh Dynasty's Crown World.
It was instantly sliced by the aerial defense network constructed by the Tomb Pyramids, exploding with a boom and transforming into a dazzling, short-lived ball of fire.
The final battle of the Sautekh Dynasty had officially begun.
Lances of light, torpedoes, and missiles poured down from numerous Imperial warships, determined to completely obliterate the dynasty.
Towering nuclear explosion flames shot up from every horizon, and shockwaves shook the entire world.
Countless burning beams and plasma streams transformed into a surging torrent of light, cascading down like a ten-thousand-meter waterfall.
Imothekh activated the Crown World's defense protocol.
A massive shield, glowing with an oily green light, enveloped the Sautekh Dynasty's Tomb Pyramids.
Countless shells and lasers rippled across the shield, yet failed to destroy it.
The Empire had only one option: an aerial drop.
Otherwise, orbital strikes alone would likely struggle to inflict serious casualties on the enemy.
It would take too long and delay the battle to intercept the tyranid swarm.
Under the Pharaoh's command, dense gauss cannon arrays and various gauss weapons fired continuously.
Dense beams of light intertwined in the air, forming a massive interwoven network of firepower.
This was intended to hinder the human aerial drop.
However, all of this was in vain.
The Sautekh Dynasty had to be destroyed; this was the supreme will of the Primarch and the manifestation of humanity's vengeance.
With a command from Guilliman.
Swarm of Stormbird gunships roared out of their hangar decks, rushing into the Crown World's atmosphere to seize air superiority from the necron fighters.
The battle instantly escalated to a fever pitch.
Pilots engaged in a desperate struggle with the necrons, with even the slightest mistake turning them into a gigantic fireball in the sky.
The Imperial fighter formations adopted loose but mutually supportive formations, overwhelming the necrons with numerical superiority.
Human fighter performance was slightly inferior to that of the necrons.
But the Empire's fighters were numerous and had fierce firepower.
No matter how strong their performance, they would still suffer defeat.
Guilliman plagiarized the firepower theory of the traitor primarch Perturabo, modified it, and incorporated it into his own operational theory.
The Primarch of the Iron Warriors, Perturabo, was a traitorous little scumbag.
But his firepower theory was not scumbag-like.
Now, the Empire's focus was on operations, on outnumbering and bullying the enemy.
Tactical infiltration? NO.
What was needed was saturation bombardment, trinity artillery support, plus equipment buffs.
What was needed was an overwhelming victory.
The enemy's unhappiness was their greatest happiness.
In space, swarms of fighters were launched, densely packed like a beehive, roaring towards the surface.
They achieved a 40:1 numerical ratio against the necrons, forming an absolute suppressive firepower.
At the same time, hundreds of landing craft detached from the Imperial Fleet's heavy transports, coalescing into a shimmering cluster of light points, like a swarm of flying insects.
Each landing craft carried tens of thousands of Imperial Astra Militarum soldiers.
Kass was in one of those landing craft.
She was to lead her troops in battle against the necrons.
When Guilliman annihilated the ork Empire and slew the Ork Warboss.
Kass was a major.
Within a few months, she had already become a lieutenant colonel.
The battlefield was always the fastest place for soldiers to be promoted.
Multiple combat experiences quickly transformed her into a seasoned commander.
Kass held a data-slate, checking the airborne situation and her unit's mission.
Her left eye had been replaced by a red-glowing bionic eye, which clicked as she rapidly reviewed the relevant data.
Her original left eye had been pierced by shrapnel from an explosion during an assault.
Thanks to her bravery, Mechanicum tech-priests installed a bionic eye so she could continue to serve the Emperor and the Primarch.
"Get ready," Kass said, holding the data-slate and trying to maintain her balance on the swaying deck.
The ship rocked violently under the enemy's artillery barrage.
Several troop transports were destroyed, and soldiers spilled out like dumplings.
That was an absolutely terrible thing.
Even though those soldiers were equipped with parachutes.
But under the enemy's dense defensive fire, opening a parachute and descending slowly was tantamount to suicide.
They could do nothing.
They could only pray that the Emperor wouldn't want to see them so soon.
Otherwise, they would just be dead on arrival.
Battlefield salvage crews could only tearfully loot the bodies, recovering all materials for future redistribution.
Kass could see her unfortunate comrades on the data-slate, their light points constantly disappearing, signifying death.
"Bad luck," Kass sighed.
On such a terrifying battlefield, luck was also very important.
Under the dual cover of void fire and Stormbird gunships, the transports successfully landed.
"Activate your auxiliary combat suits! For the Lord of Ultramar, flatten them!" Kass roared.
The others immediately responded, their shouts spreading like a tide.
"For the Lord of Ultramar!"
"For Guilliman!"
Accompanied by the voice of the machine spirit, an auxiliary combat interface appeared before Kass.
It clearly displayed the battlefield map, ammunition data, and personal physical condition.
There was also a radar minimap, assisted aiming, and ballistic calculations.
Guilliman's awakening had comprehensively strengthened the Imperium.
As the Charradon and Ultramar sectors were incorporated into his reform efforts, productivity increased, and soldiers' equipment also saw a comprehensive upgrade.
Soldiers' exoskeletons, in addition to enhancing defense, also added shoulder cannons, automatic targeting, and many other functions.
This ensured that Astra Militarum soldiers became mobile, small-scale fire platforms.
The goal was firepower supremacy, to crush all who defied them.
Kass picked up her weapon, took a deep breath, and as the hatch opened, she charged out, shouting slogans.
"For victory!"
The others followed closely, and dense red beams of light appeared on the battlefield with their charge.
As the Astra Militarum soldiers charged, the Mechanicum forces also began their aerial drop.
Those colossal ships, as magnificent as city blocks.
They resembled short, thick pipes in their external appearance.
Their surfaces were equipped with a wide variety of high-temperature resistant devices and subtly concealed deceleration thrusters.
The Titan Legions continuously deployed those terrifyingly destructive God-Machines onto the ground.
An Emperor-class Titan, three Warlord-class Titans, and numerous Warhound-class and Reaver-class Titans were deployed to the surface, forming massive fire fortresses to attack the enemy.
These enormous God-Machines possessed unparalleled power.
They were armed with massive plasma cannons and melta guns.
In addition, they were equipped with heavy void shields.
No matter how advanced necron technology was, they couldn't concentrate enough firepower to shatter the void shields of these God-Machines.
Knight Titans also formed a phalanx, launching attacks against the enemy.
Their chainswords and power weapons were activated, emitting piercing sounds that merged with the roar of the battlefield, forming a symphony of war.
The Knights, controlling their individual Titans, used the inertial impact of their charge to break into the enemy's formations, opening breaches for the ground forces.
Heavy tanks, the Skitarii's automated fire cannons, and the Onager Dunecrawlers all began to unleash firepower, furiously bombarding the enemy.
The last to land were the logistics support units.
They carried countless auxiliary supplies, including weapons, ammunition, food, drinking water, and fuel, to meet all the needs of the full-scale offensive.
The ships heading for the surface were innumerable, and the momentum of the full-scale assault was immense.
Sicarius and numerous primaris space marines had also been deployed to the surface early on; they formed the spearhead of the assault, tearing through the necron defenses, preparing to deliver the cruelest ultimate blow to dynasty.
The dynasty's resistance was fierce.
After all, this was an event that portended their demise.
Humanity used the most unyielding methods to express its wrath towards the necrons.
The surface was filled with a hail of gunfire.
Bullets converged into torrents, and the battlefield became a terrifying vortex that shredded both sides.
Imperial soldiers were enthusiastic, shouting battle cries, fearlessly charging in Guilliman's name.
As the planet rotated, the area where the necron pyramids stood soon entered twilight.
The sky gradually darkened, yet the firmament remained bright, illuminated by the energy beams of both sides.
Defense cannon arrays stood in the pyramids, furiously unleashing firepower.
In the atmosphere, phantom fighters danced, countless aircraft engaged in dogfights, firing destructive beams from their weapons, drawing ephemeral and nameless bright constellations.
The Imperial attacks converged into shining torrents, constantly washing over the necron pyramids.
Dense bolter fire was like a pervasive hailstorm.
Large numbers of necrons fell.
Then their bodies flashed, teleporting these damaged necrons back to their tombs.
Awaiting the furnace to revive them once more.
The straight gauss beams were fleeting; anything they touched was destroyed at a molecular level, turning into a pile of green-glowing quicksand.
Under the furious firepower of the necron Tomb Pyramid's defense array, Stormbirds and other aircraft occasionally turned into raging burning wreckage, falling to the ground and causing earth-shattering explosions.
As Imperial forces drew closer to the Tomb Pyramids, the fighting grew more intense.
Columns of dark brown smoke rose from the ground, reaching into the sky.
Each explosion shook the earth, and after a brief lull, continued to shower the land with scorched earth.
Fighters screamed overhead, swooping low past the lumbering Titans, deliberately disturbing the slowly rising smoke clouds into frenzied vortices.
The Emperor-class Titans, shrouded in night, advanced with slow steps, leading a vast number of human soldiers slowly towards the Tomb Pyramids.
Sicarius and thousands of primaris space marines were the first to rush into the Tomb Pyramid complex.
Their mission was to capture the Pharaoh of the Dynasty and bring a definitive end to this war.
The enemy firmly defended the passages leading to the interior.
Necron Guards, adorned with golden trim and wielding energy weapons, used defensive artillery to repel the human assault.
As Sicarius and his men poured into the tombs, they were forced to halt by the enemy's firepower.
Before they could devise a countermeasure.
Strange sounds emanated from deep within the tombs.
Large numbers of silver Tomb Scarabs crawled out from the walls and ceilings of the passages.
"Scarabs."
Sicarius' tone grew solemn as he saw these multi-legged mechanical metal beetles.
Their bodies were not large, only about the size of a primaris space marine's fist.
They glided lightly along the walls and ceilings, Pounce the human warriors pouring into the tombs.
The Scarabs' metal mandibles clicked open and closed.
Their compound lenses glowed green with gauss energy.
They swarmed like an insect horde, ignoring the destructive attacks sprayed by the human warriors.
"Attack! Cut through them!"
Sicarius drew his power sword, destroying swathes of Scarabs.
A comrade beside him stepped into the gap he had cleared and opened fire with a plasma incinerator.
Accompanied by the ozone smell of ionized air and a bright flash.
A series of orbs of light, imprisoning distorted electrical charges, were fired from the muzzle.
Creating a series of explosions along the passage.
Each plasma orb was significantly more powerful than the ammunition of a regular plasma gun.
Enough to easily penetrate the Scarabs' carapaces.
Even inflicting casualties on the necron Guards at the end of the passage.
"Use the Dreadnought to clear the way! We'll charge! Quickly!"
Sicarius shouted.
A heavy, colossal Dreadnought, like an ancient beast, lumbered forward from the rear of the formation.
"For the Lord of Ultramar!" a warrior's cry came from the Dreadnought's vox-caster.
His body was shattered, yet he was placed in the sarcophagus' nutrient tank, continuing to fight for the Emperor and humanity.
With a roar, he took heavy strides, facing the enemy's terrifying firepower directly.
Even in death, he would sing triumphantly, winning victory for humanity.
"For the Lord of Ultramar!"
"For the Lord of Ultramar!"
Sicarius and his comrades shouted along with the warrior in the Dreadnought.
