The changes on the parchment signified that the war between the Overlords and the dark creatures had entered a critical phase for the first time.
It was also the first time that the Overlords witnessed the cruelty and horror of the Continent of Overlord.
After all, in the days before, as long as one wasn't lazy and had a bit of courage, life was quite manageable.
But the Crimson Tide was different. If an Overlord did not have good relations with their minions or lacked the necessary strength, they were destined to be buried in this cataclysm targeting the Overlords.
"Catherine, instruct the Toxic Banelings to form a poison curtain AOE, let our Zerg warriors test the waters." Charles calmly analyzed as the eerie dark creatures approached closer.
It's always a good idea to probe with long-range attacks first.
Upon hearing this, Catherine immediately used her powerful mental abilities for micro-management, directing the entire group of Toxic Banelings to use their poison-spitting skill, creating a thick barrier of toxic attributes.
As the barrier was being assembled, Medusa, with her imperial might, casually waved her sleeve, sending the slowly advancing poison curtain rushing towards the group of dark creatures.
The poison corroded their bodies deeply, like a bone-deep wound.
Some of those closer to the poison curtain were directly turned into a pool of pus.
However, none of the three present were satisfied with this result.
Catherine looked grimly at the increasingly twisted dark creatures, her face darkened as she said, "Master, this time the Toxic Banelings might not be as effective. These dark creatures are clearly not flesh-and-blood beings but a bunch of rotting souls!"
Indeed, although on the surface it appeared that these eerie creatures were fearlessly charging, the root cause was the corrupted and fallen souls driving them.
Otherwise, these creatures would just be heaps of rotten flesh, long dead.
Charles nodded upon hearing this and then coldly instructed, "Have all the Toxic Banelings self-destruct. From what I've seen, these creatures can still be affected by physical damage to some extent."
"The chain reaction of the Toxic Banelings' explosions should be enough to wipe out this wave of dark creatures."
In reality, it was also a way to clear out these Toxic Banelings that had no future prospects, they were taking up too much of the food supply.
Ever since acquiring the Arms Evolution template, Charles hadn't been too concerned about the consumption of these low-tier units. Those Toxic Banelings were merely trash that hadn't broken through the first tier, perfect for clearing out.
"Yes, my master."
Catherine did not refuse. In the eyes of both the Overlord and the Queen, Zerg units were merely expendables unless they had significant potential or were Zerg heroes.
But even as expendables, the poison explosion of the enhanced Toxic Banelings was an incredibly formidable large-scale AOE attack.
After all, a mid-tier level one Toxic Baneling's self-destruction could severely injure or even kill a low-tier level two enemy. Now, with the added enhancement of toxic magic attributes, they were even more formidable!
Thus, a dazzling display of green fireworks blossomed before the eyes of the three, quickly obliterating all the invading foes.
Medusa, watching this scene with a hint of trepidation, couldn't help but praise, "Dear sister, I underestimated you before. It seems I was truly short-sighted."
"Not to mention the reactor that allows Zerg to use magic, just the Toxic Baneling alone is a perfect biological weapon!"
Not only do they provide large-scale AOE attacks from a distance, but they also deliver the strongest single-target explosive damage across tiers.
If these little critters were to evolve to tier three, even she would have to admit defeat.
Hearing this, Catherine giggled, rubbing against Medusa's big breasts, and said playfully, "I'm just an ordinary scientist. I'll have to rely on our Queen to protect me in the future~"
Medusa affectionately patted Catherine's insect antennae, causing her to mutter happily.
Seeing the harmony among his harem, Charles felt quite pleased. But then he remembered how these two slave girls had once knelt on the ground, using all sorts of methods to fight over his penis, and felt speechless.
These two naughty slave girls!
The toxic explosions from the Toxic Banelings thoroughly cleared a significant portion of the red mist from the Crimson Tide, but it wasn't over yet.
Soon, another wave of fallen souls, driving decayed bodies, arrived in this world.
They directed their wails of resentment towards the living, signaling the source of all this suffering.
Charles glanced at them. Their strength was identical to the previous ones. It seemed these were the main force this time.
Damn it, low-tier level two as the main force, and they keep coming in waves.
Charles couldn't imagine the despair of those unlucky Overlords who were stationed at the breach.
In a place where level two is considered top-notch combat power, and there's a mountain of level twos... it's utterly terrifying!
"Deploy the Jumpers and Zerglings for battle. Toxic Banelings and worms will support from the flanks and construct obstacles to disrupt the enemy's marching rhythm," Charles methodically instructed, while Catherine observed and managed everything through the information network.
This battle wasn't just a calamity, it was also a chance to acquire countless resources and opportunities for advancement.
Zerg warriors need a baptism of blood to grow stronger.
On the complex terrain, the Zerg warriors utilized the advantages created by the worms to relentlessly assault the dark creatures.
Whenever the enemies counterattacked, the Zerg would retreat and establish a second line of trenches, continuing their earlier tactics.
Seeing Catherine having a blast, Charles remarked somewhat speechlessly, "Where did you learn this military strategy? It looks as enjoyable as playing a game, making me want to join in."
Hearing this, Catherine immediately relinquished some of her control to him, giggling as she said, "This Zerg system integrates these tactics directly."
"Normally, as the Zerg Queen, I should just program the Zerg from home. But you know, I'm an unconventional Zerg Queen, I prefer bloodshed and the unknown."
It is the unknown that fuels the spirit of relentless research and exploration.
And it is through bloodshed that she reflects on the words her master spoke to her in the training room.
How can she be content with just being logistics when waging war alongside her master?
Charles smiled at her words and began to operate according to Catherine's method.
At first, he wasn't as meticulous as she was, but after a few Zerg deaths, his command abilities quickly surpassed Catherine's, even leading by a significant margin.
The Zerg moved with an eerie precision, greatly accelerating the slaughter.
Watching her master and sister command the Zerg soldiers with such deadly efficiency, Medusa wore a look of envy. Her own mental and heroic attributes didn't allow her to command such a large number of Zerg.
Catherine, on the other hand, possessed exceptionally strong mental abilities, making her a hero unit capable of micro-managing through the information network to dominate the battlefield—a strategist unit. Medusa was the top-tier combatant, the general who led the charge. As for Charles, he was the marshal, the leader who controlled the entire situation.
Generals cannot command all the troops. They can only lead elite units.
...
Two hours later, this wave of dark creatures was finally completely repelled.
Around a thousand Zerg troops had been reduced to about eight hundred. A thousand kills with two hundred losses was a decent outcome.
The most important thing was that the Zerg had overall ascended a tier, all breaking through the threshold of level two.
Among them were Zerg prodigies who had directly jumped from mid-tier level one to low-tier level two, significantly boosting the combat prowess of the squad.
Charles was very satisfied with this development. There were even signs that some of the Zerg were on the verge of breaking through to high-tier level two. Another intense battle might complete the initial step of evolving local Zerg heroes.
Such anticipation!
However, the excitement was short-lived. A dazzling black spear suddenly pierced through the body of a Zergling poised to break into high-tier level two, ending its potential.
Charles's face darkened like the bottom of a pot. He stared angrily at the headless knight slowly emerging from the red mist; it was the one who had thrown the spear!
[Undead Knight]
[Race: Undead]
[Combat Power: High-tier Level Two]
[Description: A fallen soul tainted by sin, now returned once more.]
This thing killed my Zerg hero seed?
Charles's expression was grim as the Overlord's Spear began to coalesce.
The abyssal power emanating from him made Medusa reflect with awe. Although training up to level four was indeed relatively straightforward, her master's growth rate was astonishingly rapid.
She recalled that just a week ago, her mid-tier level three strength was enough to overpower him, now, she could only kneel and await his whims.
Had she become weaker?
Seeing her master's genuine rage, Catherine used the information network to pull the Zerg away from the area.
The Overlord's Spear plunged fiercely into the knight's body, reducing the knight to ashes in an instant.
Subsequently, a chain reaction of explosions, similar to those of Toxic Banelings, ensued, clearing out a small wave of monsters!
