"This soon?"
Hearing Rozen's words, Altera froze for a moment.
As his ever-present familiar and Servant, Altera knew very well that Rozen's Magic Circuits should have required nearly another month before they could fully recover.
So why did he suddenly claim he had completely recovered?
Altera was puzzled.
Seeing her reaction, Rozen couldn't help but smile.
"Honestly, I hadn't expected it myself. But today, after lifting all restrictions on my Mind's Eye, I realized I could recover much faster."
At those words, Altera immediately understood.
"It's because of the Mind's Eye that the recovery speed is accelerated?"
That was precisely the case.
Once Rozen had released all restrictions on his Mind's Eye and began using it in its perfected state, he discovered he could not only perfectly control his mana and body, but even his Magic Circuits as well.
What did this mean?
It meant that Rozen could now comprehend every single one of his infinitely potential Magic Circuits in absolute detail, operating them effortlessly.
In other words, instead of passively nurturing and healing his Circuits, he could actively observe their internal workings, regulate his mana, and nurture them in the most efficient way possible.
With that, the recovery time of his Circuits could be dramatically shortened.
Not only that—even the ascension of his Foreign Mana could be accelerated.
After all, Foreign Mana could only be refined through the perfected state of the Mind's Eye. Now that Rozen could fully wield its power, his vision could penetrate every corner of his body, down to each and every cell, observing the progress of ascension—and, through deliberate manipulation, accelerate it further.
Thus, if his senses weren't mistaken, the time he had originally estimated could be shortened drastically.
"The recovery of my Magic Circuits, as long as I actively cooperate with their operation, should be completed within three days and nights."
"Adding the restoration of mana, five days should suffice."
"As for the ascension of Foreign Mana, about one week should do it."
In other words, after one week, Rozen would undergo a true metamorphosis—surpassing the limits of the world and reaching a realm no one had ever attained before.
Of course, during this week, Rozen could do nothing else—he would have to dedicate himself completely to adjusting his Circuits and ascending his body.
If he were unable to actively adjust and ascend, then the passive nurturing process would still take around a month, as he had initially predicted.
It was precisely after realizing this that Rozen had decisively forged contracts with Quetzalcoatl and Anna without hesitation.
Whereas with Ereshkigal, Ishtar, and Ryougi Shiki, he had relied on the mana he plundered from Ishtar to take the risk and push himself into contracting them.
But now…
"With conscious control, even if I overdraw, my Magic Circuits won't suffer any burden."
Rozen said lightly.
"In that case, making contracts with more Servants isn't out of the question."
That said, his condition at the moment wasn't great.
Providing mana for so many Servants at once had left him in a precarious state, dangerously close to collapse.
"So, what do you intend to do?"
Altera didn't press further, simply asked the question.
Rozen had already considered this.
"Unless I'm mistaken, after this battle, Gorgon won't launch another assault on the Northern Wall anytime soon."
He voiced his thoughts.
"Though our side suffered heavy losses, Gorgon also lost many Demonic Beasts. She herself may even have been injured—otherwise, she wouldn't have withdrawn, but instead destroyed the Wall outright and invaded Uruk."
Under such circumstances, even one who despised humanity as much as Gorgon would need time to breed more beasts and replenish her forces for the next invasion.
Therefore…
"I plan to use this time to restore my Magic Circuits completely, so that before the final battle, I'll be at my peak."
That way, his chances against Gorgon would greatly increase.
At the very least, Rozen did not believe that, once fully restored, he would fail against a single Gorgon.
"Ever since obtaining Cleansing, I've yet to use it at full strength."
Rozen touched the Magic Crest on his right arm and suddenly smiled.
"Now that I've gained this Magic, I wonder just how far my power has leapt forward… I want to see for myself."
Even before acquiring Cleansing, Rozen was already capable of god-slaying.
Now, once fully restored, how could he possibly fail against a mere goddess?
After all, Cleansing was lauded as the ultimate forbidden curse of god-slaying, capable of altering even the world itself.
Rozen's version had ascended to its utmost extreme—integrating the knowledge of countless worlds into one, reaching the very realm of true omniscience and omnipotence.
One could say there was nothing Cleansing could not accomplish.
If such a thing existed, it would only mean that Rozen's mana was not yet sufficient to sustain the realization of omniscience and omnipotence.
Once Rozen mastered Foreign Mana, he would likely achieve that true state, standing unrivaled.
For now, even if he had not yet reached omniscience and omnipotence, with High-Grade Mana compressed to its absolute limit, Rozen could surely perform feats far beyond what he had once been capable of.
At that time, his strength would likely be several times greater than before he obtained Cleansing.
When that moment came…
"That will be Gorgon's day of reckoning."
Rozen couldn't help but anticipate it.
Altera, however, remained silent.
It was then that Rozen turned his gaze toward her.
He didn't say anything—just quietly looked at the girl.
Meeting his gaze, Altera instinctively averted her eyes.
Seeing this, Rozen let out a faint sigh.
That sigh seemed to echo directly into Altera's heart, causing her to lower her head.
"Enough."
Rozen ended the topic.
"Help me back to my room to rest. Otherwise, I really will collapse."
Altera said nothing, simply nodded silently, and supported him back to his room.
Once there, she quietly disappeared again.
Before vanishing, she seemed for a moment as though she wanted to say something.
But in the end, Altera held back, lowered her eyes once more, and dissolved into mist, disappearing from Rozen's sight.
Rozen simply watched the spot where she had disappeared, lost in thought.
Only after a while did he lie down, close his eyes, and begin recovering his mana.
The night quietly passed.
The stars shone in the sky, illuminating the hearts of countless people.
