25 years later...
After years of traveling through the Silent Void Expanse, passing through dangerous situations, various outposts, and strongholds, they finally arrived at the Soul Pollution Lode Pool.
"Is this the soul pool?"
Outside was a massive black ocean, boiling with various illusions of death and corruption.
Around them, a mist filled with concentrated soul pollution, that could kill any tier 10 being who approached it.
Within the system, the collection of corrupted causality points steadily increased into the thousands each second.
[+1010... +1015... +1011...]
"Don't get out yet, the soul pollution is too dense," Maximus reminded, seeing them about to disembark.
"Hmm, we'll wait then..."
Calming down, they looked outside, seeing various mutated monsters roaming the place.
"The soul monsters here are too many," they gasped.
A soul monster is a creature that had come here but couldn't withstand the soul pollution.
With their souls corroding, their consciousness and origin would be destroyed, turning them into maniacal creatures that attacked anything in sight.
Looking outside, the lowest tier soul monsters were at the Tier 10 realm, and there were also several Tier 11 monsters.
"Can we handle this place?"
Even though they trusted the power of their husband, the monsters outside were no small threat.
"Don't worry, Wanderer is enough to clear out most of them. Leave the Tier 11 soul monsters to me," Maximus reassured them.
Though these creatures possessed massive strength, without control, they were just empty shells.
Soon after, Wanderer began cleaning up the Tier 10 monsters around them.
[100,023+... 100,203+... 100,004+..."
"A hundred thousand each tier 10 soul monster not bad..."
Maximus estimated that there were hundreds of thousands of tier-10 monsters here.
With a rough calculation, he could probably get about tens of billion corrupted causality points.
Coupled with the system absorbing thousands of causality points every second, Maximus felt excited.
It seemed he would get tens of billions of corrupted causality points in one go.
After a few months of absorption, the soul pollution around them began to diminish.
After tireless killing, the tier 10 monster was also cleaned, providing him with over 30 billion causality points, as expected.
Getting outside the ship, Maximus looked at the hundreds of tier 11 monsters in the area.
"This is a feast," Maximus licked his lips.
Each Tier 10 soul monster produced hundreds of thousands of corrupted causality points.
The Tier 11 soul monsters could probably produce tens or even hundreds of millions of corrupted causality points.
Taking on a tier 11 soul monster, Maximus attacked using his full power.
Thud!
Sending the monster flying, Maximus estimated its power.
"About a trillion magnitudes of power? It's much weaker than expected."
With just his bare strength without any amplification, he could demolish these monsters by himself.
...
Thirty years later, Maximus completed laying the Tier 12 Soul Controlling Array.
"Done," Maximus muttered.
This array could not only regulate the release of soul pollution, but also attack, defend, and perform various auxiliary functions.
Maximus even attempted to integrate a teleportation array, but the nature of this place made it impossible.
Opening a portal in a place filled with corrupted causality, was equivalent to suicide.
To battle such corrupted causality, a true tier 12 array capable of manipulating the causality of power was needed.
The tier 12 array he set up was barely an imitation, being at a high tier solely because of the materials.
To create a true tier 12 array, he first had to control the causality of power.
Maximus didn't even have control of the river of law; how could he dream that big?
If not for the seal of truth forceful correction, He, a tier 11 array master, would have no way of creating this rough tier 12 array.
Looking around, the place had taken on a renewed vigor.
From buildings, roads, and warehouses, to landscaping, everything was in place.
With the Tier 12 Soul Controlling Array, Maximus could easily block the soul pollution and isolate the stronghold.
Without soul pollution, even mortals could probably live here, much less the landscaping plants.
"Good job, the place looks nice," Maximus praised.
"We may have gone a bit overboard, but hearing you say that makes it seem just right." Hazel smiled.
"We'll be living here for a long time. A little extravagance is nothing."
Even Maximus used Tier 12 materials just to create the array, so what was spending some Tier 10 or 11 materials?
Before coming to the Silent Void Expanse, Maximus had spent trillions on materials.
Building such an extravagant stronghold? He could even build a hundred of them.
"Let's go to our residence and see how it works."
The residence was Maximus' masterpiece.
In the center of the soul pool stood a floating structure, taking up the core of the array.
Entering it, they felt their souls refreshed and lightened.
Although there was a slight illusion caused by the soul pollution, it wasn't as corrupted.
"Huh? Why is the soul pollution here different? It seems slightly purified."
"How is it? I didn't spend 25 years wandering in the Silent Void Expanse for nothing."
While the Shadow was en route to the soul pool, Maximus wasn't idle.
He had been reconfiguring the purification device he had found, figuring out how to use it in the Silent Void Expanse.
After years of tireless research and spending hundreds of millions of causality points, Maximus successfully deduced a Tier 12 self-repairing purification device.
Although it could still be corroded by the corrupted causality, it could repair itself with enough energy.
And the energy? Strands of causality itself.
A thousand strands were enough to power the purification device for a day.
Running constantly, all soul pollution coming toward their castle would be slightly purified, making it safe to absorb without much harm.
Training in such a place would double their progress with less effort.
"Time to cultivate..."
