Having made a plan, Maximus and his wives acted quickly.
Taking the Automated Extraction Machine into his dimensional space, they returned to the Shadow Void Land.
Calling all their family, Maximus and his wives began to share the news of their achievement.
"What? You already started harvesting the chaos grass?"
"Why didn't you tell us? We wanted to join the fun too!"
"Unfair! Why did Father and Mother have all the fun alone? We wanted to swim in the sea of plane origin!"
"Grandfather and Grandmothers are bad! How could you keep this from us?"
As they listened to the details about the extraction of the chaos grass, everyone felt a bit disappointed.
They had wanted to be part of this monumental event, where they could print plane origin and have as much as they wanted.
Who would've thought they kept it secret until now?
"Don't worry. Here, I'll let you watch."
Shielding the area from prying eyes, Maximus took out the hundred Automated Extraction Machines.
Finally, seeing the machines spitting out crystallized plane origin like candy, their expressions lit up with excitement.
Even though they had just heard about it, seeing it for themselves was a different experience.
It was like watching a money printer they could use legally for anything they wanted.
The feeling of having as many plane origin as they wanted was pure euphoria.
"Hahaha! It's time for the Shadowcrest family to rise!"
"That's right! Father, just give us the order—we'll carry it out immediately."
Buzzing with excitement, they stood in attention, waiting for their father's next command.
"First, Iris, take 10 billion crystallized plane origin and begin nurturing the Seed of Immortality. That should be enough to start."
It had only been a few years since the extraction machines started printing plane origin. So far, they had gathered just over 50 billion.
To speed up the maturity of the Absolute Seed of Path, Maximus deduced they would need trillions.
Fortunately, the Seed of Path still had to absorb the plane origin and grow.
This process would give the extraction machines plenty of time to extract all the chaos grass in storage.
Fifteen trillion chaos grass could be converted into 4.5 trillion crystallized plane origin in just under 300 years!
Meanwhile, upon hearing the order, Iris couldn't be happier.
"Don't worry, Husband. I promise to complete this task perfectly! In a few thousand years at most, the Source of Immortality will merge with the Source of Knowledge," Iris vowed, taking 10 billion crystallized plane origin from the pile.
There was nothing Iris wanted more than for her husband to grow stronger.
Besides, merging her Source of Path with the Source of Knowledge came with no downsides. In fact, it would be even stronger.
Although she would no longer have sole control over the Source of Immortality, Iris had no complaints.
They were already husband and wife, bound for eternity, moving forward and retreating together, no matter what.
"If you need any help, just ask," Maximus nodded, then turned to the others.
"As for the rest of you, it's time to upgrade your physiques to Rank 13!"
"Finally! We can upgrade our physique!"
"Hahaha, I wonder how powerful I'll become?"
"Tsk tsk… it's good to have money."
A Rank 13 physique belonged to the realm of Archons.
Although they were only at the Tier 11 realm, this upgrade meant they could wield a portion of the power that only those at the Tier 13 realm possess.
While the power was too single, it would give them enough capital to fight the overlords.
Unlike Maximus, whose auxiliary physique didn't offer much strength, most of theirs were attack-type.
Take Nathan, for example, who possessed the Death Mark physique, which allowed him to mark a part of an enemy's body. If he hit this mark, the target would die instantly.
With this ability, as long as he landed a hit on the marked spot, he could one-shot any Tier 11 Absolute.
Of course, the challenge was landing the hit in the first place.
Using such a skill on his father would be pointless, as Nathan could never land a strike on him.
Still, against dark beasts, the ability was terrifying. No matter how tough their bodies, they wouldn't survive even a second after he triggered the death mark.
Once such an ability was upgraded to Rank 13, it would become an ultimate killing skill on the battlefield.
Any Tier 12 dark beast in his line of sight could be taken out with a single strike.
Even Overlords, if careless, could be assassinated.
Such is the horror of a Tier 13 physique.
Unfortunately, upgrading a physique to that level required trillions of plane origin.
Depending on the ability, it could take up to 100 trillion to succeed.
At first, they had given up on ever reaching this goal before their father ascended to the Overlord realm.
But now, with chaos grass, anything was possible.
"Don't worry, all of you will get your share. No need to rush," Maximus said with a smile as he watched them scramble for the crystallized plane origin.
"Hahaha, we're just excited!"
Enhancing their physiques had long been their dream; how could they not be thrilled?
"There's plenty of time. Until all your physiques reach Rank 13, you don't need to do anything else," Maximus promised.
He had set aside all work, experiments, and other responsibilities. Their only task now was to upgrade their physiques.
"The same goes for you, Iris. After you merge the Source of Immortality, go into seclusion with the rest."
If he could take Iris's place, he would have done so long ago.
Unfortunately, only she could control the Source of Immortality.
"I understand, Husband."
"What about you, Maximus? What do you plan to do?"
Now that everything was arranged, they were curious about his next move.
"I'll stay behind to watch over you all. I'll manage the territory and keep things stable while you're away."
His physique wasn't something a few trillion plane origin could upgrade.
In the past, his system had shown:
[Plane Source Physique
Rank: 13 (0 / 100 trillion)
Grade: Origin (0 / 100 trillion)]
But as his cognition of the world grew, the system panel changed:
[Plane Source Physique
Grade: Origin (1 billion / 100 quadrillion)
(Requirement: Overlord Realm)]
The system, he now called the Maxim System, was bound to his core of origin.
Although it displayed his progress more intuitively, everything was shaped by his perception.
Since he didn't even know if there was a realm beyond Archon, how could he know if there was a physique beyond Rank 13?
When he asked the Heavenly System, it simply said there was no information on any tier beyond Tier 13.
No powerhouses. No materials. Nothing.
As for using plane origin to test the depth of rank 14 physique, he wasn't crazy enough to pour resources into an abyss with no visible limit.
Even if it could be upgraded, he wasn't sure his body could bear it.
After all, even a plane-level physique required him to reach the Overlord realm, let alone a level beyond his current understanding.
With nothing else to do, Maximus could only keep everything stable while his family entered seclusion.
