To speed up the development of new witchcraft capable of identifying Divine Believers, he had barely slept these past few days.
Of course, this fatigue was not due to lack of sleep, but rather a manifestation of Heart Power exhaustion.
"I can understand some of it," Colin said as he put down the manuscript and restored it to its original form.
"To understand what I have written, even partially, in terms of the Deep Red Marking Technique, you are far ahead of others," Nois said with satisfaction as he nodded his head after seeing how neatly Colin had arranged the manuscript.
Colin smiled but did not respond.
Seeing his demeanor, Nois became intrigued and paused before asking,
"Since you've understood some of it, do you grasp the problem I am currently facing?"
"The disappearance of certain traces of faith," Colin replied briefly after a moment of contemplation.
Nois gave him a look, a fleeting hint of surprise flashing in his deep eyes:
"You're not boasting then."
"I am always honest," Colin replied resolutely.
During his recent reading, his greatest revelation was understanding the essence of the Deep Red Marking Technique.
Or rather, the basis on which the Deep Red Marking Technique could differentiate Divine Believers.
This basis was a trace unique to Divine Believers.
Specifically, it was a trace of the Power of Faith that Divine Believers transmitted to the Divine after prayer.
Such an essence, if merely studying the basic Deep Red Marking Technique, would be unknown; it was cleverly concealed by Nois, with the aim of preventing it from being decrypted.
Unfortunately, it seemed that the Divine side had now developed countermeasures.
"Faith Line," Nois suddenly spoke again, "I call this trace the Faith Line.
It is an extremely hard to detect trace, not observable through normal photic vision, and not even by extrasensory perception."
"After trying countless methods, I happened to use the Douglas Shuttling Technique, and during observation in the Spirit Realm, I detected this trace.
Because it manifests in the Spirit Realm like threads of silk, I also named it the Faith Line."
Colin nodded, Nois' words giving him a deeper understanding of the Deep Red Marking Technique.
"Unfortunately, it now seems that the Divine side may have discovered this and used some method to hide this trace," Nois sighed, his hand pressing his furrowed brow.
"There's also the possibility that the current Divine spies have never prayed to the Divine, so they don't leave such traces," Colin stated.
From the portion of the manuscript he had just read, it was clear that Nois' current research direction was primarily focused on deciphering the camouflage the Divine had placed on the Faith Line.
But evidently, there was another possibility why the Deep Red Marking Technique was no longer effective.
"I have considered that point too," Nois nodded, "but I chose to first confirm whether the Divine had laid a disguise on the Faith Line."
"Besides, I am also searching for new criteria to identify Divine Believers, but so far, I have found nothing."
Rather than the disappearance of the Faith Line, he believed more that the Faith Line was being obscured by some method.
Colin, unsurprised, nodded; his own thoughts being considered by Nois was quite normal.
He had thought of it initially, but still voiced the reminder.
After all, one should not hold back a reminder just for that reason.
What if Nois had not thought of it?
The new witchcraft to identify Divine Believers was crucial for the Wizards, directly impacting him as a Wizard and every other Wizard.
"Any other thoughts?" Nois continued, his tone gentle, as if encouraging his own student.
"Indeed, I have some thoughts," Colin hesitated.
This morning, he had just passed through the Golden Paper Limit Breaking with the Deep Red Marking Technique, which mainly enhanced the scope and effect of detection, but the essential basis had not changed; it was still through the Faith Line.
So the difficulties faced weren't much of a help.
But after reading through the manuscript, he had some thoughts he wanted to share.
Colin organized his words and continued, "Lord Nois, if you want to detect whether the target is a Divine Believer, then you need to find characteristics unique to Divine Believers, such as the 'Faith Line.'
Conversely, if you can identify the Faith Line, you can determine whether one is a Divine Believer."
"In that case, it also means that by identifying the unique traces that could be caused by the Faith Line, one can indirectly determine whether there is a presence of the Faith Line and thus whether the target is a Divine Believer."
Colin paused and then added:
"Of course, this is all based on the premise that the Divine has only concealed the Faith Line, not erased it."
"Not a bad idea," Nois smiled, "Although it's just one more step of reasoning, it already far surpasses wizards of your age who rarely exhibit such clear logic and comprehensive thinking."
Nois's face bore a smile, but his gaze was calm, obviously having considered this aspect beforehand.
"However, we currently don't have sufficient research on the Faith Line, nor it is easy to identify its potential distinctive traces."
Nois further explained with a tone of regret.
However, looking at Colin, he felt slightly better.
The words he just spoke weren't meant as mere flattery for Colin.
Among the younger generation of wizards, it was indeed rare to find such clear logical thinking and analytical research capabilities.
If they were asked to learn a witchcraft, perhaps it wouldn't pose any problem.
But if they were asked to research something like—a witchcraft for identifying Divine Believers.
Upon receiving such a request, most of them would often not know where to start.
But Colin directly grasped the essence—to accurately distinguish a Divine Believer, one must naturally identify the unique characteristics that set Divine Believers apart from ordinary people and even other wizards.
After capturing this essence, his thinking continued to progress logically.
Such a mode of thinking was scarce among many School Wizards.
The reason for this scarcity was that, as the risks of researching witchcraft continued to grow over the past millennium, fewer and fewer wizards chose to engage in research, preferring instead to learn existing, low-risk witchcraft.
Thus, most gradually lost the ability needed to research new witchcraft, becoming wizards who could only rely on the wisdom of their predecessors without understanding innovation.
"Perhaps the Spirit Realm could be a breakthrough?"
At that moment, Colin thought for a second and suddenly spoke again.
'Spirit Realm…'
Nois paused momentarily and unconsciously furrowed his brow in thought.
"If the Faith Line can be observed in the Spirit Realm, it is very probable that it could also affect the Spirit Realm.
The so-called observation, whether it be visual or auditory, essentially occurs because the observed object has some impact on its surroundings, which then allows it to be perceived by the observer—
An entity that does not interact with the outside world or cause any impact is likewise unable to be observed."
Colin continued speaking, his words vaguely catching some inspiration for Nois.
But those inspirations were very elusive, like clouds at the edge of the sky that could dissipate at any moment.
Not having time to ponder further, Nois instinctively summoned his feather pen, pulled out a brand-new sheet of paper, and began writing rapidly.
Meanwhile, he didn't forget to compliment Colin.
"A deep and accurate realization—let me retract my earlier words, you are not only far beyond your fellow wizards, but even many in the True Knowledge Society cannot match your logical thinking."
Colin smiled faintly, surprised by Nois's unpretentious demeanor and openness about being inspired, but he didn't take the praise too seriously.
Praise from others was merely the gem-studded crown atop the king's head, but what made a king was not the crown.
In this violent world, everything ultimately came down to the genuine power.
