"Divine cores... in large quantities..."
Hearing Ryuga's words, Erica was momentarily speechless.
Those who know understand you're talking about Heretic Gods, but those who don't might think you're placing a wholesale order!
Can Heretic Gods of that level really be bought in bulk?
But thinking about it again, this kind of thing might not be impossible for Ryuga.
After careful consideration, she gave her reply.
"Among the magic materials already collected, there are no complete divine summoning materials."
"However, four years ago Marquis Voban successfully conducted a divine summoning ritual. Although the descended Heretic God was ultimately slain by the Sword King, the ritual itself was considered successful. The Bronze-Black Cross and the Japanese magic associations should have records of the specific ritual content."
"If Lord Ryuga needs it, I'll immediately command them to present the materials in your name."
This level of material would be very difficult to obtain without invoking a Campione's name.
Honestly, if someone other than Ryuga were asking about this, even if it were another Campione, Erica would never have brought it up.
After all, the divine summoning ritual four years ago had caused quite a few casualties.
Even her good friend and rival Liliana had barely survived that ritual.
Bringing up this type of ritual again wouldn't necessarily be good news for witches and miko with spiritual vision qualifications worldwide.
But who asked Ryuga to be the one asking?
Maintaining honesty with one's lord is the most basic quality of a knight.
"Yes, I'll leave this matter to you."
Ryuga naturally agreed to Erica's proposal.
He also had some impression of the damage caused by Marquis Voban's summoning ritual.
But it didn't matter—this level of side effect was easy for him to resolve.
The only concern was the principle behind this divine summoning ritual.
If it was a ritual based on astrological theory, then it would have high requirements for the star chart's position, very likely only having the opportunity to conduct the ritual once every few years.
This kind of mechanism determined by underlying theory would be very difficult to improve no matter how much optimization was done.
From the fact that Marquis Voban, after one success, rarely attempted to repeat the ritual, the possibility that this technique was built on astrological theory was indeed quite high.
"Yes!"
Erica immediately accepted the command.
This was the first order Ryuga had given—she absolutely had to complete it 100%!
Thinking this, Erica suddenly remembered something.
"By the way, Lord Ryuga, there's something I need to report to you."
"What is it?"
"It's about Rin."
"You might not know, but before you joined the chat group, I promised Rin that when she encountered difficulties, I would go to her world to help her."
Despite the two often bickering in the group, their relationship was actually quite good.
Knowing that Tohsaka Rin had encountered trouble she couldn't solve herself, Erica didn't hesitate much before agreeing to help.
Taking someone's money makes you beholden to them, eating someone's food makes you soft on them.
It was precisely because she was caught in this matter that Tohsaka Rin would often be at a disadvantage when facing Erica, frequently having to submit to Erica's tyranny and reluctantly call her "sister" while holding her nose.
For Erica, when she bullied Tohsaka Rin, she really bullied her, but when helping, she really helped and wouldn't go back on her word.
However, she hadn't anticipated that in the future, she would swear loyalty to someone else.
So when Tohsaka Rin truly encountered difficulties, a troublesome situation arose.
As Ryuga's knight, she couldn't act arbitrarily on her own.
"So, after completing this task, could Lord Ryuga approve a brief leave? Just half a day would be enough—I'll handle Rin's matter and return immediately!"
Erica made her request in an extremely quiet voice, constantly watching Ryuga's expression, afraid of displeasing her lord.
Asking for leave right after starting the job did seem rather inappropriate.
Seeing Erica's hesitant appearance, Ryuga pondered for two seconds before asking.
"Tohsaka Rin—what kind of trouble has she encountered?"
"I heard that a Holy Grail War is about to begin on her side, and her father wants to adopt out her younger sister in advance."
Erica immediately answered.
"Holy Grail War..."
Ryuga was slightly stunned, suddenly thinking of something.
In the Holy Grail War of the Type-Moon world, the most crucial step was summoning Servants.
According to the setting he understood, the main bodies of Heroic Spirits should be located in the Throne of Heroes outside the world, existing as boundary record belts.
Summoning Servants meant calling Heroic Spirits from outside the world in the form of avatars, granting them corresponding Classes, forming corresponding Spirit Cores, and then using the magical power provided by the Greater Grail to manifest them in the world.
From the overall process, aside from minor differences between magical power and divine power, Spirit Cores and divine cores, the ritual for summoning Servants and the ritual for summoning gods had remarkably high similarity.
The Realm of Immortality and boundary record belts were both located outside the world, and the divine core avatars worn by Heretic Gods had similarities with Class settings.
And if he could obtain Servant summoning techniques...
Didn't that mean he could modify them slightly and use them to summon gods as well?
Thinking of this point, Ryuga immediately gave his answer.
"There's no need for leave."
"Yes."
Hearing him say this, Erica thought Ryuga was rejecting her request.
After sighing in her heart, she was preparing to send a message to Tohsaka Rin with her apologies.
But unexpectedly, Ryuga's next sentence completely turned things around.
"Leave Tohsaka Rin's problem to me when the time comes."
"What? Lord Ryuga, you're actually planning to go personally?"
Erica immediately showed a delighted expression.
So Ryuga wasn't trying to refuse earlier?
"According to Rin's account, the power levels she's encountered aren't that high, and shouldn't require your personal intervention yet."
After her delight, Erica reminded him.
With Rin's father's strength, first-tier power should be enough to solve the problem.
"Don't underestimate that world, especially during the Holy Grail War period—even your current strength might not be safe."
Ryuga shook his head, then added another sentence.
"I'm also interested in the powers of that world, so it's perfect to make a trip there."
"That's wonderful! If Rin knew this news, she'd definitely be too excited to sleep!"
Not expecting the problem to be solved so perfectly, Erica felt relieved while being somewhat happy for Rin.
With this big shot providing escort, what was there to fear?
