Facing the Chimera, Rozen could now understand the difference between Phase3 and Phase4.
It's not a difference in the magnitude of power but a difference in scale.
If we only consider the power, Phase4 doesn't necessarily surpass Phase3.
The classification of spiritual disasters is primarily based on the physical damage they can cause and their own scale, not their strength.
Regardless of how strong, if a spiritual disaster can't cause physical damage, it's classified as Phase1.
Even if it can cause physical damage, as long as it hasn't fully materialized into a dynamic spiritual disaster, it's Phase2.
Similarly, if it can't generate a large number of spiritual disasters centered around itself, then no matter how strong it is, it falls into Phase3.
On the contrary, even if it's not strong on its own, if it can generate a large number of spiritual disasters centered around itself, it will be categorized as Phase4.
Hence, even Phase4 isn't necessarily stronger than Phase3.
Take Hokuto for instance, as Miyachi Iwao mentioned, strictly speaking, it's also a Phase3 spiritual disaster. But it has its own consciousness, has existed for thousands of years, and has boundless potential, far surpassing ordinary dynamic spiritual disasters.
In this world, there are also Orge-type spiritual disasters that have formed clear personalities after being born and stabilized over hundreds or even thousands of years.
For example, the Kakugyouki that Yakou once subdued is a Orge king that has existed for over a thousand years. Not only does it possess clear intellect, it can perfectly control its own power.
Though it's still classified as a Phase3 dynamic spiritual disaster in terms of grading, after thousands of years of accumulation and strengthening, its power can easily crush the current Phase4 without any suspense.
However, if the power isn't strong but the scale is large, it's still enough to pose a threat.
If we liken long-standing Orge to high-pressure water guns, when they erupt, their power far exceeds water that hasn't been compressed and jetted. But if the water is too much, even if you open the valve, the instantaneous surge of the massive flow can wash away everything.
Phase4 is like this.
The expansion of scale allows it to generate hurricane-like miasma even when it roars. Its own resistance to exorcism becomes even more formidable.
Facing such a spiritual disaster, the entire Exorcism Division needs to be mobilized.
Not because they need to assemble all the exorcists in the Exorcism Division to match it, but to successfully exorcise it, it requires a large amount of manpower and spiritual power. Otherwise, it's difficult to succeed.
That's the current situation.
Even though Kogure Zenjirou and Kagami Reiji are both exceptionally powerful, even if they face the Chimera one-on-one, they can hold their own, and perhaps a balanced battle doesn't necessarily mean they can exorcise the Chimera.
So, in the end, it's certain that Kogure Zenjirou and Kagami Reiji will exhaust their spiritual power and be defeated, or they'll have to wait for reinforcements from the Exorcism Division to come and join forces before they can exorcise it.
Therefore, Rozen wasn't sure if even with him added, it would be enough to exorcise Phase4.
However...
"————————"
Rozen joined his palms and closed his eyes, paying no heed to the reactions of everyone present, and began chanting the incantation of the "Fire Realm Incantation" with utmost focus and concentration, surpassing any previous chanting.
Under this chant, with Rozen as the center, the flames began to ignite.
Witnessing this scene, everyone present widened their eyes.
Including Kogure Zenjirou.
Including Kagami Reiji.
Even those in the audience, watching the battle from the stands, led by Kurahashi Miyo, were shocked.
Why?
Because what was presented before them was the "Fire Realm Incantation" like no one had ever seen before.
In a word, it was enormous and divine flames.
The flames didn't form into a wave, nor did they form an explosion. They seemed to have gained life, sometimes transforming into flame dragons, sometimes into fire snakes, sometimes into blazing lions, and sometimes into scorching giants, forming around Rozen.
According to legend, Fudou Myouou had eight great attendants.
The eight great attendants were mostly young boys, but when facing evil and enemies, they would transform into various forms to represent extermination and removal of all malevolence.
At this very moment, the "Fire Realm Incantation" used by Rozen appeared as if the attendants of Fudou Myouou were manifesting successively, burning away the Chimera's miasma completely and aggressively advancing towards it.
"Oooooooooo...!"
In this moment, the Chimera's cry carried a sense of fear.
Not only the Chimera, seeing the power of the "Fire Realm Incantation" displayed by Rozen, Kagami Reiji and Kogure Zenjirou were equally astonished.
"How is this possible...!"
Kagami Reiji exclaimed directly.
Kogure Zenjirou was equally filled with amazement.
"That's Chief Miyachi's...!"
In Kogure Zenjirou's tone, there was a deep sense of unease.
The subduing technique of Fudou Myouou—the "Fire Realm Incantation"—which could burn away all demonic forces, turning the world into a scorched wasteland.
This technique, originally, was a secret art possessing the power to burn away everything.
To be able to truly manifest its power and possess the ability to burn away all, perhaps, it was difficult for a person with outstanding talent to emerge within ten years. Only after years of harsh practice and training could this technique become something that could be used at a basic level.
As for the one who could demonstrate its true power, giving it the ability to burn away all, perhaps, even hundreds of years might not produce such a person.
If there is someone capable of using the "Fire Realm Incantation," then even with just this spell, they would be able to burn away all kinds of jujutsu, shikigami, and enemies.
This kind of technique has been organized within the Pantheon, making it easier for people to activate, but it's only the activation. Only one person in the world can truly unleash the power of the "Fire Realm Incantation" to its full potential, and that person is the Chief of the Exorcism Division known as the "Fire Demon"—Miyachi Iwao.
In other words, even a National Level Onmyouji like the "Twelve Divine Generals," to be able to manifest the "Fire Realm Incantation" to its true extent, there is only one person in the entire world, and that person is Miyachi Iwao.
Because of this, Miyachi Iwao also holds a title—the strongest contemporary Onmyouji.
Now, Rozen, although the "Fire Realm Incantation" he chanted may not yet surpass Miyachi Iwao in terms of power, he has already delved into the true essence of the "Fire Realm Incantation."
Being able to discern all phenomena in the world, perceive the changes in the microcosm, perfectly control magic, penetrate the weaknesses of enemies, and then complement his own weaknesses with the "Mind's Eye," Rozen discovered the essence of the "Fire Realm Incantation" and proceeded to master it.
Perhaps an ordinary "Mind's Eye" wouldn't achieve such effects.
However, Rozen's "Mind's Eye," having undergone two transformations, had long been comparable to legendary saints and high-ranking monks. It could grasp the true meaning of Fudou Myouou's subduing, as if it were a matter of course.
Therefore, Rozen devotedly chanted the complete "Fire Realm Incantation" method with all his heart and soul, causing the flames to take the form of Fudou Myouou's eight great attendants, burning away the miasma, covering the entire training ground.
The terrifying flames raged like this, transforming this space into a mythical world.
