With the assistance of numerous Imperial heroes like the Saint Celestine, Chapter Master of the Ultramarines Marneus Calgar, High Marshal of the Black Templars Helbrecht, Inquisitor Greyfax, and countless loyal Imperial soldiers,
Guilliman easily suppressed the invading Chaos forces. Wielding the Emperor's Sword, he freely reaped any enemy within his sight.
Whether they were Plague Walkers, Furies, or Daemonettes, they were cut down like weeds.
Piles of bodies fell, stacking up.
Having merged with a new soul, the Primarch's power showed no signs of weakening; instead, it grew even stronger.
Guilliman's resurrection excited countless Imperial loyalists.
The Primarch's god-like figure filled their hearts with courage and strength, allowing them to face the terrifying Chaos entities without fear.
Guilliman's appearance greatly boosted the morale of the Imperial forces. The Archmagos Dominus of the Mechanicus, Cawl, also joined the battlefield. Chanting the Litany of the Omnissiah, he sniped at the Chaos warriors who attempted to surround him.
The powerful weapons embedded in his spine, powered by the energy core in his chest, unleashed countless terrifying beams, annihilating the Chaos forces that tried to stop him.
The Chaos forces retreated step by step. The Primarch's arrival on the battlefield continuously tilted the scales of victory towards humanity.
Wherever Guilliman's gaze fell, the daemons and corrupted warriors there would tremble in fear.
The flaming Holy Sword in his hand became the symbol of the battlefield; wherever it went, enemies were annihilated like dry weeds.
Guilliman moved through the enemy ranks as if unopposed. The Emperor's Sword danced in his hand, and no enemy dared to confront him.
Only the appearance of a Chaos daemon managed to slightly slow his pace.
The daemon was enormous, with an ape-like face and broad horns.
Power armor crafted ten thousand years ago covered the daemon's strong, bone-spiked body. In its hand, it held a chainsword burning with crimson flames.
Its crimson skin stretched taut with every swing of its arm, and strange patterns covered its blood-red wings.
A powerful aura of rage emanated from the daemon, echoing in the minds of everyone on the battlefield, making people angry and irritable.
Warriors who tried to stop him from approaching the Primarch were all killed.
Celestine and others attempted to intervene but were stopped by Guilliman; he intended to kill this daemon himself.
"I didn't expect to see another Primarch appear on the battlefield."
The daemon's yellowish-brown eyes were full of mockery. He stared at Guilliman, saying, "It's a pity, the age of the Primarchs has passed, and the Imperium of Man will also fall. What can the son of the Corpse-Emperor do? You cannot stop the coming tide; this universe belongs to the Chaos Gods."
Guilliman frowned. He recognized the symbols on the remnants of power armor on the opponent's body: the World Eaters.
A Chapter that once served the Imperium but ultimately joined the ranks of the traitors.
Due to their gene-father, the World Eaters generally chose the side of the Blood God, Khorne.
This daemon before him had clearly gained the favor of the Blood God and ascended to daemonhood.
Looking at the traitor from ten thousand years ago, Guilliman, holding the Emperor's Sword, retorted without hesitation, "Traitor, I guess we didn't hit you hard enough ten thousand years ago, daring to crawl out of that dog hole known as the warp."
The soul within Guilliman was merely merged; he still retained his past memories. He still felt immense anger towards these damned traitors and wished he could slaughter them all.
At the end of the Great Crusade, the Imperium of Man was stable, only awaiting the success of the Emperor's final great project—the Webway. Humanity would then embark on an incredibly bright path, becoming the most excellent race in the universe.
If not for the betrayal of Horus and several other Primarchs, humanity would not have fallen into its current state of darkness.
Humanity would have long since followed the Emperor's plan, moving towards psychic ascension and collective sublimation.
All that beauty was turned to ash with the betrayal of Horus and the others.
The warp's cancerous growth has since been deeply rooted in the Imperium of Man.
Since the Emperor sat upon the Golden Throne, humanity has struggled in the dark galaxy for ten thousand years.
Each day of survival has been bought with the corpses and blood of countless warriors, a price so heavy that no one can measure it.
Every moment the wheels of history turned was filled with the lives of countless heroes.
And all of this was thanks to these followers of Chaos.
Just as Guilliman was looking for the daemon's weakness, trying to completely eliminate this damned traitor.
To make the other party understand that even if they sided with the Chaos Gods, a weakling is still a weakling.
"Verbal provocations are useless. Primarchs and the Imperium will become a thing of the past. From now on, there will only be war and slaughter in the galaxy. The skull of a Corpse-Emperor's Primarch will be the greatest gift to my master."
The daemon snorted, and hot sparks shot out from its nostrils.
The flames on his body burned fiercely, and the space around him warped and glowed from the intense heat.
"Go back and tell your foolish master that his bloody throne will be my trophy. One day, I will cut off his big head and use it as a ball to kick around."
Guilliman's gaze was fearless. With the help of the Dominus Aegis, he was absolutely confident he could defeat the opponent.
Imperial soldiers and civilians who saw the Primarch would become followers. The Dominus Aegis would help him convert the faith provided by these followers into power.
It's like a god gaining more power the more faith they receive.
The more followers Guilliman gained, the stronger his power would become.
The power of a Primarch combined with the blessings of numerous followers' faith meant defeating a Greater daemon of the warp was not a difficult task.
The Greater daemon was enraged by Guilliman's insult to the Chaos God he served. He roared, the ground shook, and thunder rumbled in the sky.
The daemon's power was unleashed, terrifying the Imperial soldiers on the battlefield. Their bodies, holding lasguns, couldn't help but tremble. The Chaos forces were ecstatic; they howled in praise of the terrifying daemon, hoping he would lead them to conquer this world.
The Greater daemon took heavy strides, charging towards Guilliman.
He swung the greatsword in his hand, attempting to kill Guilliman and take his skull to offer it before the Blood God's throne.
"You have slept for ten thousand years, while I have honed my skills day and night in the warp. Today, even if you are a Primarch, I will tell you that you will surely die."
The daemon roared. His power was incredibly terrifying. The Baneblade tank scattered before him was casually swatted away by a wave of his hand.
He swung the greatsword in his hand, delivering a powerful, heavy blow towards Guilliman.
Guilliman swung the Emperor's Sword, blocking his attack. The collision of the two created a shockwave that swept across the surroundings.
The daemon roared. Guilliman seized the opening and delivered a punch. The power field of his power fist was activated, and crackling, ethereal blue arcs of light tore through the air.
The sound of rushing air filled the space, and an invisible afterimage appeared in the air.
The daemon was knocked to the ground.
The massive daemon's body slid for over a dozen meters across the ground, crashing into a wrecked Leman Russ Demolisher before coming to a stop.
"Is that it? Ten thousand years of training and this is the best you've got? You're a wet paper tiger, anything that melted in the Warp doesn't toughen up. Go tell Khorne to wash his neck clean, because I'm coming for his head."
Guilliman looked at the daemon he had knocked to the ground with a single punch and immediately switched to taunting mode.
In a fight, facing numerous Chaos Gods and their minions, Guilliman couldn't say he would definitely win.
But when it came to taunting and drawing aggro, he was an absolute master.
Back in the day, on forums and in group chats, he was invincible, sweeping everyone aside.
As for whether taunting the Chaos Gods would invite retaliation, that wasn't really a big problem.
The Chaos Gods all had some limitations and couldn't enter the material universe.
The rules of the universe restricted these Chaos Gods; at most, they could only dispatch their daemons. Furthermore, with the Emperor's existence, he wouldn't allow the Chaos Gods to enter.
He cursed them, and Khorne couldn't do anything about it.
"You dare insult my master??" the daemon roared after getting up.
"I'll do more than insult your master, I'll put you six feet under myself."
Guilliman strode forward, leaping and slashing at the opponent's head.
