"How is the harvest?" Maximus asked, seeing Liam come in.
"I've purified 30 billion dark beast bodies, yielding 315 Tier 12 ultimate materials," Liam reported.
Not wanting to deal with such a miscellaneous task as purifying dark beast bodies, Liam had assigned it to the stronghold.
By providing strands of causality to wash off the dark energy, anyone could purify a dark beast's body.
"Not bad. Your sisters didn't ask for a share?"
"They did, but I didn't give them any," Liam said emotionlessly.
"Oh, you've suffered." Maximus patted his shoulder, sympathizing with Liam.
With those brats used to getting what they wanted, Liam might have to endure a silent treatment for a while.
"It's for their good." Liam didn't care.
As the eldest, Liam had grown up disciplining his younger brothers and sisters.
Knowing their nature, how could he not predict the results of his actions?
Those little goblins had been giving him headaches since they were young.
Fortunately, there was Lily, who had taken the role of the gentle eldest sister.
With her around, his sisters should calm down for a while.
"Anyway, Father, what do you need these ultimate materials for?"
Having already created enough micro-surveillance bots to monitor the entire Dark Void Domain, there should no longer be a need for such a large quantity of ultimate materials.
"Hahaha, I'm planning to create an artificial ultimate weapon! Come, I'll show you."
Under Liam's puzzled gaze, they entered a secret room in the laboratory.
From its shape, it looked like a Dimensional Pulse Blaster—a weapon of mass destruction capable of obliterating Tier 10 and Tier 11 individuals like plants and weeds.
Although it wasn't enough to harm a master of the path of law, it was still a major dimensional weapon that all top sects and families needed to possess.
He remembered his father had even exchanged at least ten quotas with the Tower of Knowledge for a thousand of such weapons of destruction.
However, unlike the Dimensional Pulse Blasters of the Aeon Plane, the one before him was magnified a million times.
Liam couldn't even see the entirety of the weapon.
Just looking at its size, Liam felt a threat of death.
"W-what is this, Father?!" Liam asked in shock.
"This is the Orbital Pulse Blaster, aka the Overlords Killer."
Getting external help was never as good as relying on one's own ability.
Although Zar was quite obedient, Maximus didn't know when their cooperation would come to an end.
Coupled with the overlords hanging over his head, Maximus couldn't wait to create an ultimate weapon of his own.
Capitalizing on his unlimited energy, Maximus had long been planning to create such a weapon.
Unfortunately, it wasn't until he discovered the dark beasts that could constantly produce ultimate treasures that he began this project.
"Liam, what are you doing here?" Erica asked.
"He's here to see what we've been busy with."
Maximus couldn't create such an ultimate weapon alone.
With the help of his wives, Maximus could divide his attention between other tasks.
From enhancing the micro-surveillance array to studying Zar, without their help, Maximus wouldn't have time for this.
"Mother, so you're here."
Liam had long been curious about what his parents had been working on.
Seeing the colossal weapon before him, it was obvious.
"How powerful is this weapon?"
"Its attack was just a hundred trillion magnitude of power," Maximus shook his head.
Maximus's magnitude of power himself was in the hundreds of trillion.
Amplifying it to the millions or even billions, the Orbital Pulse Blaster was still far from his ultimate vision.
"It's already quite strong."
Even if Liam did his best, a few hundred trillion in magnitude was the peak of his capabilities.
With an attack that could instantly kill a master of the River of Law, it had already entered the rank of a Tier 12 dimensional weapon.
"It's still too weak."
Maximus planned to create a weapon that could threaten or even kill an overlord.
To reach such power, he needed to enhance the Orbital Pulse Blaster by billions or even trillions of times.
Fortunately, by studying Zar's physique, he had made some breakthroughs.
After this upgrade, he should be able to increase its power millions of times.
Having the power to harm a master of the Ocean of Law would already make him satisfied.
Taking Liam to admire their masterpiece, ambition seemed to fill his heart.
"How much more ultimate materials do you need, Father?"
"As many as possible."
If Maximus had billions of ultimate materials, he wouldn't need to think so hard.
With just a few modifications and arrays, he could create a weapon capable of threatening an overlord.
"As many as possible…" Liam repeated, falling into deep thought.
Thinking of the talents in the stronghold, it seemed he needed to implement a major reform.
For the ultimate weapon of the Shadowcrest family, he could only let those talents suffer a little.
"Don't worry too much. We still have a lot of time."
With the steady supply of ultimate treasures and a lab rat full of buried potential, Maximus was confident he could construct what he envisioned.
No matter how long it took, he would finish this Overlord Killer.
Meanwhile, at the edge of the Aeon Plane, the overlords defending against the dark beasts felt an ominous premonition.
"What is it? Is something wrong with our plan?" Ascelon asked with a frown.
"Let me check the array," Frir said solemnly.
They couldn't afford for this plan to fail.
After spending trillions of epochs, they had gambled everything on this plan.
If it failed, not only would their work be wasted, but the Aeon Plane would cease to exist entirely.
"Tsk, I said things were going too smoothly. There must be something wrong!" Elvian added.
With Maximus supporting them from behind, everything had gone too smoothly.
Even problems they hadn't anticipated were easily resolved by him.
If this continued, they wouldn't even have to do anything to finish this dark disaster.
Suddenly, feeling this ominous premonition, it seemed a problem was about to surface.
"Hey, we can only hope the problem isn't too big."
