Normally, such a powerful ghost artifact would not be used lightly.
However, to deal with Uchiha Madara, the Soul-Devouring Prison-Guarding Banner was borrowed by the Ghost King for the Undying Ghost King. The main purpose was to fix Uchiha Madara's soul and prevent him from using his teleportation techniques to escape.
At the same time, this banner greatly amplified the banner holder. After use, it could command additional ghost laws, and its ghostly energy was inexhaustible, almost allowing the banner holder to become immortal and indestructible under the banner's coverage.
Indeed, after the Prison-Guarding Banner was unleashed, the Undying Ghost King's original A-grade 96th Ghost Rank realm began to surge rapidly, reaching a terrifying level 98.
He was only one step away from level 99.
"Soul-Devouring Prison-Guarding Banner? Interesting!"
Upon seeing the appearance of the Prison-Guarding Banner, Uchiha Madara felt his soul tighten abruptly. An immense power descended from heaven and earth, enveloping him.
His soul felt like it was trapped in a quagmire, unable to extricate itself.
He could feel that if he used the Flying Thunder God Technique at this moment, it was possible that his body would teleport, but his soul would remain in place.
This was only because the level of the Undying Ghost Emperor, the one activating it, was not high enough. Therefore, the Prison-Guarding Banner could not capture or destroy his soul, but it could temporarily confine his soul within this realm, preventing him from leaving.
Uchiha Madara did not feel fear. Instead, a bloodthirsty smile filled with fighting spirit appeared on his face.
"Only with you like this are you qualified to make me go all out!"
Ghostly energy surged and permeated the surroundings, dyeing the heavens and earth a pitch-black color.
Compared to ordinary A-grade ghost domains, the ghost domain formed by the Undying Ghost King in conjunction with the Soul-Devouring Prison-Guarding Banner was undoubtedly much more terrifying.
The massive ghost domain, like an inverted bowl, spread outwards at an extremely rapid pace. Wherever it passed, ghost laws ran rampant. All plants, upon being covered, withered, aged, and rotted at the fastest speed, eventually turning into dust.
Within this ghost domain, even the laws of the human world were suppressed. If ordinary law-level ability users were trapped within, they might be directly tortured and disintegrated by the ghost laws and the Soul-Devouring Prison-Guarding Banner in an instant, becoming beings similar to vengeful spirits within the ghost domain, never to be freed.
Trapped within, Uchiha Madara's Susanoo could not completely evade the erosion from the laws. Under the impact of the endless ghostly energy and laws, Uchiha Madara's Susanoo was rapidly weathering, and its light began to dim.
The energy armor of the Susanoo was dissipating, and its body was undergoing sublimation. The dim energy skeleton began to reveal itself.
But was Uchiha Madara an ordinary law-based powerhouse?
Clearly not.
"I acknowledge you, Undying Ghost King!" Uchiha Madara's lips curled into a frenzied smile. "In the realm of immortality laws, I, Uchiha Madara, declare you the strongest!"
"But this is far from enough!"
His wild laughter echoed through the heavens and earth. Uchiha Madara's pupils dilated abruptly. In an instant, two ferocious rifts appeared in the void behind him. The four-dimensional rifts were completely torn open, and within those rifts, the phantom images of two colossal Rinnegan were embedded in the endless void, madly absorbing energy from the void.
The way Uchiha Madara tore through the void was so wild and brutal that even the Soul-Devouring Prison-Guarding Banner and the ghost domain could not restrain him.
"This is... a spiritual anchor?"
The Undying Ghost King, clad in colossal black armor, stood towering in the heavens and earth, his thousand-zhang-tall ghostly body reaching into the sky. Within his hollow eye sockets, black and white soul flames flickered intensely, signifying the turmoil within his heart.
The void was divided into four dimensions. With each deeper layer, the law energy became more violent and chaotic, but the law attributes contained within encompassed almost everything. It was difficult for any person, divine ability, or bloodline technique to take root and leave a mark.
Yet, at this moment, deep within the four-dimensional void, a pair of Rinnegan, transformed into energy and identical to Uchiha Madara's, were forcefully embedded within it. Behind those eyes, countless fine threads seemed to pierce through various dimensions, connecting to the void barrier of Earth from other locations, providing it with a continuous stream of Earth's law energy.
"How is this possible? You are clearly not S-rank, nor have you touched the threshold of S-rank. Why can you leave your spiritual will anchor in the dimensional void? This is a realm that only S-rank can control and level 99 can reach!"
The ghost fire in the Undying Ghost King's eye sockets flickered as he roared.
All A-ranks were equal, but the reason why level 99 could stand above all A-ranks below level 99 was not only due to their comprehension of more laws, but more importantly, because their spiritual will was rooted in the endless dimensional void, allowing them to freely utilize all law energies of the same attribute.
Their own laws were the light, and the laws in the dimensional void were the darkness. The combination of light and darkness could unleash power far exceeding that of ordinary law-based powerhouses.
For example, if the fire laws in the present world and the extreme yang laws in the four-dimensional void were intertwined and fused, they could transform into the crimson flame laws. The flames condensed by these laws could be comparable to the Samadhi True Fire of Taoism, capable of burning anything. Ordinary Earth fire laws, upon encountering them, would be directly assimilated and unable to stir any waves.
To fuse two similar attribute laws, the first step was to establish a spiritual anchor in the dimensional void, and then to refine and control the laws in the dimensional void day and night, only then would there be a slight chance.
Within the dimensional void, there were small worlds constantly evolving and perishing. Naturally, there were also indestructible laws similar to immortality laws. However, the Undying Ghost King had attempted to establish dimensional anchors countless times, and all had failed.
He never expected that what he had been pursuing for so long would be mastered by this man, who eight years ago had not even reached the law level, before him. How could he accept this?
Hearing the Undying Ghost King's words, Uchiha Madara gave a sinister smile. "If you must ask why... it's because I am Uchiha Madara!"
As his words fell.
The originally light purple swirling Rinnegan turned a deep, rich purple. As they opened and closed, a terrifying pressure emanated.
In an instant, the Susanoo, which was about to be submerged by the death laws of the ghost path, was infused with new, terrifying energy. Under the interweaving of the terrifying energy, the damaged Susanoo began to rapidly replenish and become complete.
Boom!
After being replenished, the overflowing energy intertwined again, causing the thousand-zhang Susanoo to grow to a height of two thousand zhang. Simultaneously, the entire Susanoo turned a deep blue.
The transformation had not stopped.
Under the illumination of the energy Rinnegan embedded in the void, the outer surface of Uchiha Madara's Susanoo began to be covered with a layer of purple flowing light, reflecting the surrounding area enveloped by the ghost domain into a purple expanse.
Noble, majestic, powerful.
This was a brand new Susanoo.
"Next, are you ready to die?! Undying Ghost King!"
"Universal Pull!"
