If she could still understand thirty percent of what came before, then what Ryuga explained afterward, she completely couldn't comprehend.
Although for Ryuga it might be basic theoretical knowledge, and if it were the developer of this technique, careful consideration might allow understanding of his thought process, but Erica couldn't.
As a user of the technique, she herself didn't understand much about the principles of magic, let alone technique improvement.
Since even Erica looked completely bewildered, needless to say about the others.
[Madoka: "I didn't expect even Erica-Nee couldn't understand. Suddenly I don't feel so bad about myself."]
[Kanae: "I couldn't understand anything throughout, so I actually don't feel pressured."]
[Kanae: "By the way, where's little Rin?"]
[Madoka: "Can Rin-Nee still keep up?"]
If classified according to the TYPE-MOON world, Erica belonged to mages who only applied magic but never researched the principles behind it.
Compared to Erica, Tohsaka Rin's environment was closer to that of a pure researcher.
If not for her young age, she should be the one most capable of understanding Ryuga's thought process in the group.
Under everyone's calls, Tohsaka Rin appeared.
[Tohsaka Rin: "I could still understand a little at the very beginning, so I lowered my head to take some notes."]
[Madoka: "And then?"]
[Tohsaka Rin: "Then I couldn't understand anything."]
Though she had only looked down for an instant, she felt like she had missed the entire history of magical research.
When she looked up again, she could no longer understand even the terminology Ryuga was using.
[Madoka: "..."]
[Erica: "..."]
[Kanae: "..."]
This brief lesson resulted in total defeat for all of them.
Seeing everyone's reactions, Ryuga shook his head without much disappointment.
[Ryuga: "Based on your comprehension assessment, for now you should buy the versions sold in the group store - at least they guarantee learning success."]
[Tohsaka Rin: "I don't know why, but I suddenly feel like I'm being treated like a monkey."]
[Madoka: "Rin-Nee, is it possible that's not an illusion?"]
[Tohsaka Rin: "Shut up! Even if it's true, don't say it out loud!"]
Rin covered her ears, trying to escape reality.
She was a magical genius her father was proud of, not a monkey who couldn't understand basic knowledge!
Except for Rin, the others didn't have such strong self-esteem.
[Madoka: "I feel somewhat sorry for big brother."]
[Kanae: "Yes! Lord Ryuga has already shared knowledge worth thousands of points for free, yet I completely couldn't understand."]
Entering a treasure mountain but gaining nothing - at times like this, they could only blame their own insufficient intelligence.
[Kanae: "I feel ashamed of my illiteracy level."]
[Tohsaka Rin: "I feel ashamed of my illiteracy level."]
[Erica: "I feel ashamed of my illiteracy level."]
[Madoka: "I feel ashamed of my illiteracy level."]
Regarding the copy-paste responses in the group, Ryuga expressed no opinion.
He didn't care about those few points, and was accustomed to seeing others' expressions as if listening to gibberish.
He had seen such scenes countless times on the faces of scientists from various countries in his world - nothing surprising about it.
"This dimensional leaping technique is actually not as difficult as you imagine. The operational core is simply replacing Hermes' traditional symbol of the caduceus with symbols representing communication and trade crossing... forget it, we'll discuss this later. Right now there are more pressing matters to handle."
Shaking his head, Ryuga temporarily gave up on the teaching task, his gaze turning toward the coastline ahead.
There, the divine beast boar, now burning with blue flames all over its body and obviously completely enraged, was glaring menacingly at them.
With Ryuga's reminder, everyone finally noticed that the divine beast boar had already escaped from the seabed.
Even knowing Ryuga possessed Second Order strength, they couldn't help but show worried expressions.
"Does Lord Ryuga intend to eliminate it?"
The perceptive Erica asked.
If the goal was just to escape, they could directly use Ryuga's optimized magic to leave far away, without needing to wait for the opponent to climb ashore.
"Mm."
Ryuga nodded slightly, not hiding his intentions.
If he had only wanted to help Erica escape danger, he wouldn't need to come personally - just selling a random life-saving skill would be sufficient to ensure Erica's safety.
His reason for actively requesting to come to the Campione world wasn't truly altruistic, but had his own purposes.
Through analyzing [Hermes' Boots], Ryuga had roughly mastered the construction method of conceptual equipment.
But even so, this was only Saint Magician or Paladin-level power.
To advance further, he needed to personally contact the most pinnacle and mainstream power of this world.
—Gods!
The divine beast boar before him was an excellent opportunity.
Not only could he test the various powers he had comprehended, but he could also analyze the essential nature of divine existence up close - killing two birds with one stone.
Thinking this, Ryuga looked back at Erica and extended one hand.
"May I borrow your sword?"
"Ah, no problem!"
Faced with Ryuga's request, Erica unhesitatingly handed him her beloved sword that had never left her side since childhood.
Then she suddenly remembered something.
"Wait, Lord Ryuga, I remember you haven't purchased any offensive-natured powers, right?"
Regarding Ryuga's comprehension, current Erica had no doubts whatsoever.
Just with dimensional leaping alone, he could be called a Saint-level magician.
But with just mana and dimensional leaping these two skills, there was no way to cause any effective killing damage, right?
Could he really subjugate a divine beast this way?
Faced with this worry, before Ryuga could speak, someone explained for him.
[Kanae: "Um, Erica, Lord Ryuga has purchased offensive skills - the Flame Breathing from my side."]
[Kanae: "However, this level of power probably won't be useful, right?"]
As she spoke, Kanae herself lacked confidence.
Even if Breathing techniques were practiced to their peak and multiplied tenfold, they seemed to have no possibility of confronting an enraged divine beast.
Compared to gods, human Breathing techniques still seemed too weak.
Facing this doubt, facing this worry.
Ryuga said nothing, only silently gripping the sword hilt.
Sensing his will, Erica immediately held her breath, afraid of disturbing Ryuga's performance.
Accompanied by earth-shaking shockwaves, the divine beast boar that had climbed from the sea charged forward again with its signature ramming attack, swearing to crush these two fleas that had toyed with it into powder.
Facing this identical assault from before, facing this offensive capable of easily crushing mountains, seas, and cities.
Ryuga's expression remained calm, his pitch-black pupils reflecting all things like mirrors.
The moment the divine beast boar charged to his front, he firmly gripped the sword hilt and softly began chanting word-spirits of the same type as conceptual equipment.
"Indra, submit! Agni, submit!"
White-purple lightning and red firelight simultaneously covered his body's surface.
Just as he had borrowed Hermes' power, through conceptual equipment's construction ritual, Ryuga easily borrowed a small portion of the Thunder God's and Fire God's power.
And the next step after gaining buffs was eruption.
Five Elements Breathing Technique Secret Art.
Secret Sword: Fire Thunder God!
Azure lightning and blazing fire flashed in intersection, and Ryuga's figure had already crossed past the divine beast boar, time seemingly frozen completely at this moment.
The next instant, the divine beast boar, motionless like a statue, completely crumbled and turned into golden light particles.
Then, the massive impact sound finally echoed throughout the entire island.
