The dim light was like a brilliant firework, annihilating all the dark creatures that stood alongside the Undead Knight.
Seeing that the creature was killed by his own hand, Charles said with a grim expression, "Dispatch our elite biological weapons, the Blade Bugs. Those high-grade creatures must not break the rules."
Besides that Undead Knight, there were other high-tier level two entities lurking around, like cunning old shadows.
Catherine nodded and then signaled the nearby Blade Bugs to join the battle.
In truth, compared to the native species that hatched from eggs, Blade Bugs were more like consumables. Or rather, judging by their attributes, they were destined to be mere expendables.
The synthesis formula for these creatures was simply materials plus seasoning, leaving no room for any value appreciation. They were essentially super soldiers that could be copy-pasted as long as resources were available.
Their only real advantage was that equipping a Blade Bug with a Queen's Blade generally elevated its combat power by a tier.
In the next second, those powerful Blade Bugs, each with a unique appearance, surged into the war.
The scales of victory began to tip, and the battle resumed with renewed ferocity.
Gradually, the crimson mist dissipated, thinning until it vanished entirely.
As Charles observed the now-cleansed forest, his previously relaxed expression turned serious.
If the Crimson Tide had truly subsided, the Continent of Overlord should have acknowledged his efforts with some form of reward, rather than maintaining this unsettling silence.
Sure enough, another wave of dark creatures attacked, and this time the monsters were at tier three!
They had pure purple bodies, with terrifying tentacles twitching mindlessly, floating in the air like ghosts.
[Ephemeral Beings of the Underworld (Larvae)]
[Race: Ephemeral Beings of the Underworld]
[Combat Power: Low-tier, Level Three]
[Skills: Undead Screech, Ephmeral Tremor]
[Description: Ordinary ephemeral creatures connected to the Lands of the Underworld, typically found at the boundary between life and death]
Great, these things made Charles fully realize exactly where he was—
Near the Underworld, damn it!
No wonder there were so many dark creatures here. It turned out this place was connected to the Land of the Dead, and even served as a boundary point!
The Land of the Dead was a place that Charles would have fled from in his previous life upon hearing its name. The weakest beings emerging from there were at least tier three, with no upper limit!
In that realm, the Ephemeral Beings of the Underworld were so weak that even the most insignificant entity could bully them.
He let out a slow sigh and used the information network to command the remaining 300 elite Zerg to retreat gradually.
The current battle had surpassed what mere soldiers could handle. Tier three creatures could wipe them out with a mere breath!
Those Zerg were invaluable treasures, each with the potential to evolve into Zerg heroes. Their lives couldn't be squandered so carelessly.
Moreover, it was just fifty or so Ephemeral Beings of the Underworld. The three of them could handle that on their own!
At that moment, Medusa stepped forward and volunteered, "Master, it is time for your servant to prove her worth."
"You should know, I have trained an entire Serpent Legion equipped with military formations. These Ephemeral Beings of the Underworld are surely no match for us!" As she mentioned the Ephemeral Beings of the Underworld, a hint of apprehension flickered in Medusa's eyes.
Even the Serpent Empire could not hope to contend with such formidable entities... Fortunately, the Realm of the Dead spanned the entirety of the Continent of Overlord, and these ephemeral beings were merely ones that had slipped through tiny fissures.
They were not worth worrying about!
However... Medusa couldn't fathom why creatures from the Underworld would appear alongside the Crimson Tide. Was there a connection between the two phenomena?
Or was it merely a coincidence?
Charles seemed to realize something and then nodded, "You're right, we still have our military formations."
He had experienced firsthand just how formidable these formations were a few days ago!
Medusa then rallied her Serpent regiment, charging like a pack of hungry wolves.
[Abyssal Serpent Soldier]
[Race: Zerg]
[Combat Power: Mid-tier, Level Two]
[Skills: Thousand Insects Devouring Heart Formation (fully staffed with fifty members, capable of contending with mid-tier level three armies when a totem is present), Mastery in Spear Techniques]
With such impressive stats, they could directly leapfrog a major tier in combat. This was something beyond the imagination of Charles, who had once been a tier-six minor Overlord.
And now, Medusa, the regiment leader, willingly submitted to him.
Medusa briefly hovered in the air, her stunning figure exuding an air of domineering determination. She let out a cold snort.
An overwhelming aura spread out, causing the Ephemeral Beings of the Underworld to falter momentarily, instilling them with fear.
This was Medusa's Eye of Lust.
This versatile skill could amplify imperial might and killing intent to intimidate lesser beings, or, in more intimate settings, accelerate arousal for herself and Catherine, making them quickly wet and ready for their master's pleasure.
A truly versatile skill.
After momentarily repelling the Ephemeral Beings of the Underworld, Medusa smirked coldly and then infused her Serpent Emperor's shadow into the military formation.
The formation's totem began to glow.
The Zerg Serpents underwent a transformation, charging fearlessly at the Ephemeral Beings of the Underworld. Their climbing aura rapidly advanced to the level of low-tier, level three.
After a brief warm-up, they reached mid-tier, level three.
With this newfound strength, the Serpent soldiers fought like deities, swiftly clearing out the Ephemeral Beings of the Underworld, showcasing the formidable power of the military formation.
Medusa watched, satisfied, and then leaped to Charles's side, saying, "Master, I've wrapped up this battle for you."
The Crimson Tide should be over by now, right?
Charles shook his head slightly, his tone somber, "Foolish slave, take another look. The real boss is about to arrive."
Based on the usual pattern of the Crimson Tide, there had to be a true mastermind behind all this.
And he was right. The final boss appeared before the Ephemeral Beings of the Underworld were fully eradicated...
A larger version of the Ephemeral Beings of the Underworld.
[Ephemeral Beings of the Underworld (Complete Form)]
[Race: Ephemeral Beings of the Underworld]
[Combat Power: High-tier, Level Three]
[Skills: Underworld Invasion, Ephemeral Tremor, Gate of Hell]
[Description: Fully matured but still the weakest combat unit in the Underworld.]
Seeing the high-tier, level three Ephemeral Beings of the Underworld, Medusa was about to step forward to clear it, but Charles stopped her, "This time, let your Master handle it. After all, I am the Master, am I not?"
Medusa paused, then solemnly replied, "You will always be my Master in this life. I will only ever be your sex slave. If that's the reason, let me handle it for you."
Charles gently patted Medusa's head, his tone warm, "It's alright. Your Master is just feeling a bit idle. Though it is a high-tier, level three Ephemeral Beings of the Underworld, don't forget, I am a Zerg Overlord!"
"A mere leap in combat level is as trivial as drinking water or eating food!"
Hearing his immensely confident voice, both Catherine and Medusa felt an overwhelming urge to submit to him immediately.
Perhaps it was only such a powerful Overlord, who dared to challenge higher levels and remained vigilant even in comfort, that could win the hearts of these two women?
Having said that, Charles spread his expansive Overlord wings and swiftly flew towards the Ephemeral Beings of the Underworld.
As he faced the high-tier, level three entity, a smirk of disdain appeared on Charles's lips.
He had once been a tier-six Overlord. How could he be intimidated by a mere tier-three creature from the fringes of the Underworld?
"Overlord's Spear!"
A black spear materialized in his hand, and with a cold expression, he charged at the Ephemeral Beings of the Underworld.
The Ephemeral Beings of the Underworld, enraged that a mere mid-tier level three dared to challenge it.
Let out a piercing screech, unleashing an overwhelming wave of purple Underworld aura.
Sensing the threat of this aura, Charles casually twirled his spear, sending a gust of wind that returned the Underworld aura back to the Ephemeral Beings of the Underworld. This was the essence of magical attribute manipulation.
Unfortunately, being a creature of the Underworld, the Ephemeral Beings of the Underworld sustained minimal damage from its own aura. It only paused momentarily.
Then, like a malevolent specter, it unleashed countless tentacles, each covered in suckers capable of draining any creature dry upon contact.
As the tentacles surged towards him, Charles remained expressionless, swinging his spear once more.
Flames of darkness incinerated the tentacles completely.
The Ephemeral Beings of the Underworld continued to attack Charles relentlessly, but none of its attempts even grazed him.
Finally, growing impatient, it resorted to its ultimate move—
Gate of Hell!
