"You wish! I'll kill you!" the Nurgle daemon roared. "I'll imprison your soul and entertain you with a million phages, so you understand what it means to live a life worse than death."
"Do you think you can win?" Guilliman's tone was mocking. "By disgusting me to death with your repulsive appearance? In that case, there's a slight possibility."
"Alright, game over, daemon. Time for business. What font do you prefer? I, in my benevolence, will allow you to choose a font and language you like." Guilliman swung the Emperor's Sword, and a terrifying power erupted from his body. The heavy, powerful strike severed the Nurgle daemon's weapon.
The Emperor's Sword's flames made the Nurgle daemon fearful, and it retreated several steps. Guilliman stepped forward, pointing the Emperor's Sword at its opponent.
"Tell me your name, daemon," Guilliman said, placing the Emperor's Sword at the Nurgle daemon's heart. "It's best to be respectful, don't make me change my mind. Otherwise, I don't mind killing you. You know what this sword is, right? It will completely end you. As long as I stab into your body, you won't even be able to return to the warp, but will turn into brilliant, pure nothingness in the golden flames."
The Nurgle daemon looked at the burning Emperor's Sword, fear in its eyes.
It knew what this was, the Cursed One's weapon. It would completely annihilate the daemon's soul.
In the previous battle, many lesser daemons had their essence utterly destroyed by this sword.
Gurlak saw this and tried to rush over to help the Nurgle daemon.
If that daemon was killed, its plan would completely fail.
Father's power would recede, the warp storm would be quelled, and this world would not become Nurgle's Garden.
"Your enemy is me, traitor."
Sicarius blocked it, his power sword clashing with the opponent's battle axe. The immense recoil made Sicarius's body tremble.
Gurlak was also not having an easy time. Its obese body, which strained its Centurion armor to the breaking point, shook even more violently than Sicarius's.
The maggots on its body fell to the ground, and the flies crawling on the surface of its armor buzzed and flew up, forming a dense black cloud.
A space marine nearby pulled the trigger of his flamer, and a stream of fire erupted. The flies were burned to charcoal, falling to the ground and emitting a foul smell.
"Get lost," Gurlak roared, swinging its plague axe at the opponent's head.
"I'll allow you to do that. You're so round, you'll definitely roll very fast." Sicarius parried the opponent's battle axe, continuing to block it to buy time for the Primarch.
Looking at the Emperor's Sword slowly approaching its heart, the Nurgle daemon finally chose to surrender.
It didn't want to die.
"I am a Great Unclean One of Nurgle, Gast the Slow." The Nurgle daemon spoke its true name.
"A Great Unclean One? So small? Gast the Slow, you truly are a waste." Guilliman mocked.
Anger surged in Gast the Slow's heart, but it could only endure it.
One day, it would have its revenge.
This time, it was purely due to its carelessness, entering the real universe without using its full power.
Otherwise, it would never have been defeated so easily.
True names are the daemons' weakness. By controlling their true names, one can enslave or banish them.
However, there is one point: the true names of daemons cannot be used casually.
Even ordinary people chanting these names can cause Chaos corruption, turning them into unspeakable monsters.
Many similar incidents have occurred in Imperial history, where people chanted the names of daemons, and the daemons were not controlled, but they themselves became monsters.
This is especially frequent among rogue psykers.
The Imperial Creed, the Inquisition, the Grey Knights, and the Assassinorum all seal away related Chaos knowledge to avoid contamination.
Guilliman is a Primarch, possessing warp characteristics and the cheat's power of dominion, which can convert human faith into strength. Naturally, there are no major issues.
Not only can he chant the opponent's true name, but he can even easily banish the opponent.
"Very good." Guilliman swung the Emperor's Sword, directly severing Gast the Slow's limbs, and then carved "Waste - Gast the Slow" onto its chest.
"You can get lost now. Remember to give Mortarion a message: I will come looking for him. If you don't want to be found by me, then hide as soon as possible."
As Guilliman spoke, the limbless Gast the Slow felt an invisible force pulling at it.
The real universe was rejecting its existence.
"I'll be back." Gast the Slow wanted to say something harsh, but Guilliman's gaze made it swallow its words. It was afraid that if it shouted, Guilliman would change his mind and kill it with a sword.
The Nurgle daemon was banished back to the warp.
"No!" Gurlak felt the receding warp power and cried out in despair.
Its painstakingly long plan had failed just like that. Gurlak couldn't accept it.
Having dealt with the daemon, Guilliman turned and walked towards Gurlak, who was fighting Sicarius.
He had his own plan for letting the Great Unclean One go back, but there was no need to keep this leader of traitors.
Gurlak and Sicarius were still able to trade blows.
Facing the Primarch, it was instantly defeated in just one move.
Its battle axe was severed by the Emperor's Sword.
"This planet solely belongs to the Imperium." With that, Guilliman thrust his sword into Gurlak's chest, completely ending it.
The other daemons were also banished or voluntarily fled back to the warp.
If they didn't run, they couldn't win either.
The Imperial side had already gained the upper hand, and staying would not change anything.
One must know that even if daemons are not completely killed by ordinary attacks.
If they are destroyed, they still need to wait in the warp for resurrection.
The time spent waiting for rebirth is extremely long and requires the permission of Father Nurgle.
Guilliman understood that killing that Great Unclean One was useless.
Nurgle could create them again.
The most important thing now is to consolidate the Imperium and deal with the attacks from the traitor Primarchs.
The Chaos Gods are currently being contained by the Emperor, and they are also fighting fiercely among themselves, so the problem is not very big yet.
Unless they realize that Guilliman's threat is as great as the Emperor's, they will only join forces to deal with him.
Otherwise, the Gods will only target the Imperium incidentally when fighting other Chaos Gods.
Even if Guilliman carves insults to Nurgle, it won't open a portal just to fight Guilliman specifically. In that case, its home would be destroyed by the other Chaos Gods and the Emperor.
The biggest problem now is the traitor Space Marines and Primarchs.
Daemons cannot enter and exit the real world freely. Only the various rituals and sacrifices of cultists can allow them to obtain bodies to enter the real universe.
Only those traitor Space Marines can enter the real world at any time.
Only those Primarchs are idle enough to plot various schemes against Guilliman.
If his memory is not mistaken, Magnus, Fulgrim, and Mortarion are the Primarchs who will attack him.
It's a good thing to draw these guys out sooner rather than later, otherwise, the enemy is hidden while he is exposed, which is very disadvantageous.
He is already outnumbered, and the opponent is hiding in the dark. This battle is too difficult.
"If my identity wasn't questionable, I would have to find a few loyal Primarchs to come back and work." Guilliman grumbled in his heart.
The Primarch of the First Legion, the Emperor's first tool, Lion El'Jonson, who was most likely to contend with Horus for the position of Warmaster, should be sleeping in the Tower of Angels, which is The Rock. It is also not ruled out that this guy was sent to the past or future by warp currents.
What a useful tool. He can fight and endure, and if he is brought here as a target, at least the pressure won't be so great.
The Primarch of the Eighteenth Legion, the Undying, Vulkan, should be on Nocturne. During the War of the Beast, he was active for a period and eventually vanished with the ork Warlord.
Of course, according to the undying nature of the perpetuals, Vulkan will not die, he will only stay in death for a period and then resurrect, even if his body is gone. He is a proper real-life daemon.
The most likely place for Vulkan to be is Nocturne.
Unfortunately, Guilliman cannot go looking for these Primarchs, at least not before he has completely taken control of the situation. He cannot look for these people.
Primarchs are definitely among the smartest people in humanity.
Guilliman felt that they would guess his identity, and then the situation would become complicated.
It can even be said that the Dark Gods, the Emperor, and other beings will guess his identity and the changes in him.
As for how long it will take, that is hard to say.
In any case, before things get worse, his best option is to take control of the situation as quickly as possible.
Guilliman does not want to gamble his life on the attitudes of the Emperor and the other Primarchs. Once he makes a mistake, he will be doomed, and humanity will also be doomed.
Another civil war, and it will basically be over.
The battle ended, and the soldiers cheered for victory.
Especially those from planet Sara, who were all crying with joy.
"Clear the battlefield, execute all the traitors, rescue the wounded, check on the condition of the civilians, and have them send a representative to find me." Guilliman suppressed his thoughts and made arrangements.
