I summoned the Fourth Scourge in Warhammer

Chapter 204 There are no tactical nuclear weapons here.
Inside the headquarters, the air was so heavy it seemed to have solidified.

The only light in the room came from a large holographic tactical console in the center, on which a shaky and chaotic video was playing on a loop. When the last frame of the video froze on the terrifying Tyranid creature filling the entire frame at an incomprehensible speed, the light from the tactical console illuminated the solemn expressions on the faces of the three Space Marines and the EGO.

The projection went out, and the room fell into a brief darkness and silence, with only the low hum of the server and life support system remaining.

The tyrant of the Great Vortex, Rugert Huron, was the first to break the deathly silence. He leaned back in his chair, his massive power armor crossed over his chest, and his voice carried a hint of caution: "Let me confirm first, this video isn't fake, right?"

“Of course not,” EGO replied calmly. “This is the last image our warriors just captured with their lives.”

“I’m actually more concerned about why the Chaos Enemy appeared in Plantim,” said the Ultramarines Second Company Commander Agman seriously, his upright posture like a statue, “and why he fought Tyrannosaurus to the death.”

Before EGO could answer, Huron let out a disdainful snort: "Hmph, Chaos is like a cockroach. By the time you find one, the dark corners are already overflowing. Don't forget, this used to be an agricultural planet, and these green creatures love places like this."

“You’re right,” Agman nodded, forcefully steer the conversation back on track, “Let’s get back to how to deal with this…”

At this point, Agman paused, his gaze shifting to EGO, awaiting a precise designation.

“We call it the Norn Messenger,” EGO explained at the opportune moment, “because it has no independent thought of its own, but is a pure flesh and blood vessel that carries the will of the Hive, created entirely to accomplish a specific goal.”

“Very good, a fitting name.” Huron nodded, leaning forward slightly. “So, do you, the Deathbringers, know its weaknesses?”

“Hmm…” EGO pondered for a moment, “Anti-protoplasm bombs can solve it.”

“By the Emperor,” Huron couldn’t help but complain, “Anti-protoss bombs can certainly solve it, and I also know that Cyclone torpedoes can! The problem is that they’ll send us all to heaven together!”

EGO calmly stated, "So it seems you lack confidence in dealing with it?"

Agman's voice was low as he admitted, "I can't even see its movements."

“I can barely see it,” Huron said with a serious expression, “but I doubt I could last ten seconds against it.”

Only Cato Sicarius remained silent, only the slight grinding sound of his clenched fists could be heard.

“Alright, but there’s no need to worry too much.” EGO instinctively tried to boost morale. “The power that the Tyranids can unleash is not limitless. The swarms they sent on Plantim will inevitably reach a peak, which is the upper limit of biomass consumption they can withstand. In any case, the arrival of this Norn messenger has greatly brought forward that peak.”

"Is this why you want us Astartes to remain stationary and let the mortal legions take on the initial defensive duties?" Huron keenly grasped the deeper meaning in his words.

“Yes,” EGO readily admitted. “The power that any force can exert has a peak and cannot grow indefinitely. In this situation, it is not a good thing to exert power to its peak at the beginning, because after that, it will only go downhill.”

“This is more like a philosophical idea than a tactical or strategic one.” Huron showed some interest in this argument. “So you Deathbringers believe that as long as we kill this Norn messenger, these annoying bugs will retreat?”

“Considering the Primarch’s flesh and blood are right before our eyes—excuse my choice of words—I think one might not be enough, perhaps we need to add a few more?” EGO said. “Isn’t that a bit too difficult?” Agman said bluntly.

“Ahem,” EGO coughed, “Actually, we who are ready to die also have the power to reinforce the battle.”

"What is that?" Agman asked immediately. "Do you have a Shadow Sword super-heavy tank?"

EGO replied, “No, it’s the Orglin. We can gather at least three thousand Orglin. While they may lack agility, their pure strength and physical prowess surpass that of the Space Marines, making them a key factor in the outcome of the battle.”

“Oglin? Let’s forget about it.” Huron shook his head without hesitation, his face full of distrust. “Excuse me for being blunt, but with Oglin’s intelligence, they would only make things worse for an enemy of this level.”

EGO gave a strange smile: "Our Oglins who go to their deaths are different from ordinary Oglins. You'll see in a moment."

“Alright,” Huron said noncommittally, “then let’s assume that for now. Do you have any specific tactics for dealing with this Norn messenger?”

“Yes,” EGO said. “No matter how powerful a single Norn messenger is, it’s impossible to completely wipe out the entire Plantimus with just one insect; that would be an extremely inefficient option. So its role must be to break through and decapitate: to use its unparalleled destructive power to tear a gap in our defenses, allowing the Tyranid swarm from the rear to flood in; or to use its speed to raid command posts at all levels, decapitating our brains and paralyzing the entire human defenses.”

“A very reasonable assumption,” Huron nodded slightly. “If it were me, I would make the same choice.”

“Yes, that’s exactly what we’ve been waiting for.” EGO’s voice rose. “When that Norn messenger appears at a command post… we’ll immediately detonate the tactical nuclear missile that’s been planted underground at the command post!”

Huron's pupils contracted slightly, and he pressed, "Which command post?"

EGO replied: "Every command post."

This answer caused the three Space Marines present to instinctively turn their gazes to the solid alloy floor beneath their feet almost simultaneously.

“Well, this command post doesn’t have tactical nuclear weapons,” EGO’s first sentence eased their tension slightly.

However, the second half of EGO's statement instantly raised their anxiety to an unprecedented level: "...strategic nuclear bombs are buried here."

Huron remained silent for a full three seconds before slowly rising from his chair, his massive frame exuding an intense aura of pressure. He glanced at Agman and Sicarius, whose expressions were equally grim, and then said to EGO in an extremely serious tone, "I think we need to find somewhere else to talk..."

“I agree,” Agman immediately seconded.

“Me too,” Sicarius replied.
