He could even set it up for others. *Maybe I should set one up for Asuna?* He decided to consider the details later. Regardless, having this system would be incredibly beneficial for his allies.
Ren Isana quickly memorized the entire Greater Grail system. After performing a mental simulation to ensure there were no errors, he finally stopped. The next step would be to complete the system and fully realize the [Materialization of the Soul], which would grant him eternal youth.
Immortality... the ultimate pursuit of countless emperors throughout history. Now, it was within Ren Isana's reach. A slight smirk played across his lips as his mood brightened significantly.
The next order of business was to enter the [Root of Akasha]. Ren Isana turned his gaze toward Leonardo da Vinci. It was time to fill the Holy Grail. He had originally planned to fill it himself, but since Leonardo da Vinci had come up with a new plan, he naturally intended to let her handle it.
"Master, give the order. I will disperse my Magic Power and maintain my Spirit Graph." Leonardo da Vinci spoke these words aloud; she was ready to begin her preparations at a moment's notice.
Ren Isana looked toward Morgan and Artoria. Morgan simply gave him a faint nod, making her intentions clear—she was going too. That only left Artoria.
She had only just joined and learned the truth of these matters. He wondered what she would choose. Would she tag along to have some fun in another world, or would she choose to return to the Throne of Heroes?
*Seeing her sister again should make her happy, right? She'll probably want to tag along for the trip.* Ren Isana felt a sense of amusement. He didn't actually know if Artoria was happy, but Morgan certainly seemed pleased.
"I... I will go too!" After a moment of hesitation, Saber decided to follow her sister. After all, Morgan was hardly a good person. There was no telling what she might do in another world, and as a righteous King of Knights, Artoria felt it was her duty to keep watch.
"I am going as well!" Having made up her mind, Artoria glared at her sister with eyes full of wariness. This reaction left Morgan feeling slightly confused.
*What's with the look, little sister? Looking for a fight? You got a problem with your big sister?* Morgan raised an eyebrow and asked, "What? Is there a problem?"
Artoria said nothing, silently averting her gaze. She couldn't defeat her sister, so what choice did she have? This version of Morgan was terrifyingly strong, far beyond what she remembered from her past.
"Then let's begin. By the power of the [Command Spell]!" Seeing that all three intended to go, Ren Isana didn't waste time. He raised both hands, revealing his [Command Spell].
The three Heroic Spirits turned solemn at his gesture. There were tasks that Heroic Spirits might struggle to complete on their own, but a [Command Spell] could ensure they were carried out successfully.
Under the expectant gazes of the three Heroic Spirits, Ren Isana slowly commanded, "Return your Magic Power to the Holy Grail and place your consciousness within your Spirit Graph!"
With that simple order, the three Heroic Spirits acted immediately. Their Magic Power dispersed instantly, dissolving into points of golden light before Ren Isana. In their place, three glowing golden cores appeared.
"Master, you must collect us quickly. At the same time, activate the Greater Grail immediately, or else Alaya and Gaia will interfere." As he collected them, Leonardo da Vinci's voice echoed in Ren Isana's mind.
Upon closer inspection, the three cores looked exactly like chess pieces, representing their respective classes. Ren Isana stowed them away without a moment's hesitation.
Alaya and Gaia, who had been observing from the shadows, were suddenly filled with questions. *Wait, what is this kid doing? Why did he take the Spirit Graphs? And why can't we sense them anymore?*
Ren Isana didn't give them a chance to react. Having stored the three Spirit Graphs, he immediately activated the Greater Grail!
The Magic Power was sufficient, and all seven Servants had been accounted for. The Holy Grail began to manifest as the Lesser Grail floating in the air merged into the Greater Grail. In a flash, a pitch-black cavity was torn open in the void.
Then, a deluge of black mud began to pour from the hole. Just looking at the mud was enough to cause discomfort, as a wave of intense negative emotions washed over the area.
Every magus in Fuyuki City felt this presence. Irisviel, who had already awakened, was filled with shock upon sensing this aura of pure malice.
Kiritsugu Emiya remained silent, smoking quietly. However, his trembling hand betrayed his inner turmoil. Ren Isana had been right; the Holy Grail truly was corrupted.
Even from this distance, he could feel that overwhelming malice. He could only imagine how terrifying it would be to stand directly at the source.
Ordinary people couldn't sense it, but for magi, the sensation was profound. A regular person might only feel a vague sense of unease, but a magus felt as if the entire world was targeting them.
At Mount Enzou, Ren Isana watched the black mud flow down. He said nothing, simply using [Spatial Magic] to isolate the cavity while condensing a spear of light in his hand.
With the [Holy Spear] chambered, Ren Isana watched the mud continue to pour out. Without hesitation, he flew forward, spear leading the way, and charged directly into the hole.
The black mud seemed sentient as it surged toward him in a frenzy. However, it was held back by the radiance of the [Holy Spear]. The moment he entered the cavity, Ren Isana hurled the [Holy Spear] with all his might.
He also activated his [Incarnation of the Sun]. As his body began to radiate light, the black mud retreated as if it had encountered its natural enemy. But Ren Isana had no intention of letting it go so easily.
"Dissolve beneath the radiance of the sun!" Ren Isana whispered. The light intensified until it looked as if a sun had dawned inside the cavity. The black mud was instantly purified.
Possessing the [Incarnation of the Sun], Ren Isana held the power to cleanse all filth in existence, and the Evil of This World was no exception. Under this power, it melted away like butter against a hot iron.
Alaya and Gaia, who were still observing, were pleasantly surprised. Requesting his help had indeed been the right choice; the Evil of This World was finally being dealt with. The two wills exchanged a glance and breathed a sigh of relief.
With this, another major headache was resolved. It was a sweet deal. Although the two usually didn't get along, they were perfectly aligned on matters like this.
However, their joy was short-lived. Ren Isana continued to radiate solar light while observing his surroundings. As the black mud dissipated, a new opening appeared.
Ren Isana's eyes lit up at the sight. After sensing the area for a moment, he frowned. He could feel Heroic Spirits guarding the other side. No doubt, that was the path leading to the [Root of Akasha] and the Throne of Heroes.
But Alaya and Gaia had stationed Heroic Spirits to block it. If he tried to pass, he would likely be stopped immediately. They were guarding the place as if he were a thief!
Ren Isana was instantly annoyed. *So they really do intend to just make me do their dirty work? Treating me like some slave? You're not even going to give me a chance to reach the Root? Fine. If that's how you want to play, don't blame me for throwing firecrackers in your house.*
He said nothing, silently condensing another [Holy Spear]. This one was stronger, larger, and far more terrifying in power. Alaya and Gaia, still distracted by their joy over the purification of the Evil of This World, failed to notice this detail.
By the time they reacted, it was already too late. Ren Isana had finished charging the attack. Looking at the hole below, he threw the [Holy Spear] without a second's hesitation.
"This strike shall pierce the Root!!" A terrifying pillar of light erupted from Ren Isana's hand, hurtling directly toward the opening of the Root. The Heroic Spirits stationed there by Alaya and Gaia were stunned by the incoming aura.
In particular, a certain white-haired young man in red clothes sensed the dangerous energy and cursed out loud, "Is he crazy? He's attacking the Root directly?"
He had never seen anyone so outrageous. Who in their right mind would attack this place? Weren't people supposed to come crawling over, hoping for just a single glimpse inside?
But this guy didn't follow common sense at all. He launched a [Holy Spear] directly at the entrance of the Root. The man in red didn't hesitate; he leaped forward to intercept, using [Projection] to manifest a [Noble Phantasm].
A pink flower bud bloomed as [Rho Aias] appeared to block the way. This was none other than Archer. Since he was so versatile, Alaya loved making him work, and naturally, he was the one sent to handle this.
Unfortunately, a hastily deployed [Rho Aias] stood no chance against Ren Isana's fully charged [Holy Spear], which now carried a [God-Slaying] attribute. The flower bud was punctured the moment it appeared, and the light swallowed him whole.
Ren Isana had noticed him the moment he jumped out to release [Rho Aias]. He had witnessed the entire process of the [Projection] magic firsthand.
"I see. Thanks for the gift, bro!" With a single look, Ren Isana's [Jianjigu] allowed him to master the skill perfectly. He gave a mental thumbs-up. This guy was a real pal; Ren Isana had been planning to study [Projection] eventually, and the guy had just given him a live demonstration. Learned it!
But now wasn't the time for that. Ren Isana's [Holy Spear] pierced straight through the entrance of the Root and into the Throne of Heroes, carving a straight, unstoppable path through the entire place.
Alaya and Gaia were completely dumbstruck. Their minds were buzzing in disbelief. They never could have imagined Ren Isana would do something like this. He actually attacked? He threw a [Holy Spear] into their Throne of Heroes?
The strike tore through the Throne of Heroes, forcibly creating a direct road to the Root. As the [Holy Spear] struck the Root itself, the entire [Root of Akasha] began to boil, rapidly assimilating the energy of the attack. In that moment, Ren Isana saw the information contained within the Root!!!
