Just as lively as the Butterfly Mansion was the chat group itself.
Erica: "Exactly! Lord Su Mo is unparalleled in wisdom and peerless in beauty!"
Erica: "Wait, no! How can you guys see what's happening here?"
Only after escaping danger did she realize that the whole incident had been live-streamed.
Rin Tohsaka: "Don't ask us, we have no idea either!"
Madoka: "The moment the big brother went over, the group live stream started automatically."
Erica: "Let me see..."
Erica: "I see. The 'Invite to Traverse' function defaults to enabling the group live stream. This can be turned off manually."
Previously, although they all knew about the group traversal function, since it was a paid feature, none of the impoverished members had ever tried it.
And in that life-or-death moment, Erica certainly hadn't had the time to worry about default settings; she had just summoned Su Mo over. Only now, upon closer inspection, did she realize it was a settings issue.
Rin Tohsaka: "I suggest you don't turn it off. I want to see how Lord Su Mo defeats the Divine Beast!"
Madoka: "+1."
Erica: "I don't have a problem with it, but we'll have to ask Lord Su Mo."
Saying this, Erica looked up at Su Mo, her gaze inquisitive. Not only had he just saved her, but even setting that aside, a powerhouse's battle footage could potentially leak information.
Although Erica herself didn't care about that, she didn't feel she had the right to make that decision for Su Mo. If he wasn't willing, she would turn off the stream without a second thought.
Even though she'd feel bad for her little sisters in the group, the powerhouse was right in front of her. She knew where her priorities lay.
Su Mo naturally understood Erica's meaning and immediately shook his head.
"It's fine."
"Knowledge should be circulated and shared. If you can gain something from this, that is your own good fortune."
Rin Tohsaka: "Yay!"
Madoka: "Thank you, big brother!"
Since Su Mo didn't mind, Erica naturally let the live stream continue.
"Oh, right. Lord Su Mo, the power you used just now was...?"
Seeing that the Divine Beast Boar hadn't yet climbed out of the sea, Erica couldn't contain her curiosity and asked.
"There's no need to doubt. It was also the Boots of Hermes."
Su Mo glanced at the cautious blonde knightess and knew instantly what she was curious about.
"You want to ask how this technique can be used for dimensional leaps?"
"Yes!"
Erica nodded like a chick pecking at rice. This was her commonly used magic. When could she reach such a level?
"It's actually very simple. The Boots of Hermes technique belongs to a conceptual Spirit Armament system of magic. Unlike traditional magic systems based on mana mechanisms, the core of this technique isn't acceleration or lightening the body, but the divine name."
Su Mo explained casually while analyzing the Greater Source mana environment of this world.
"The divine name?" Erica's eyes lit up with curiosity.
"Correct. The theoretical basis of this magic system is idol worship. Therefore, the amount of mana provided is not as important as the imitation of the divine name. This is the key to enhancing the technique's effect," Su Mo explained eloquently.
"As a god, Hermes' existence spans Greek, Roman, and Egyptian mythology. His divine offices are diverse. He is the messenger of the gods, one of the twelve Olympians, and also presides over the domains of alchemy and magic. In esoteric traditions, he is even called the 'Hidden God'."
"However, for this particular technique, we only need his divine office as the protector of travelers. Therefore, when constructing the spell, we must try to eliminate interference from his other divine offices."
"In the Age of Gods, symbols representing Hermes were often marked near villages, towns, temples, and national borders, signifying him as the god of boundaries and the crossing of boundaries."
"For travelers, seeing the symbol of Hermes meant they had entered the next territory. Travelers often prayed for the protection of the god Hermes. Based on this belief, the Boots of Hermes technique has the effect of increasing agility and leg strength..."
"...The original technique you use is constructed from this belief. Can you understand up to this point?" Su Mo confirmed after rapidly explaining the technique's principles.
"Umm... I can probably understand about half of it!"
Erica already looked a little dizzy. In truth, "half" was her putting on a brave face; she had actually understood less than thirty percent. And this was her best performance.
Kanae: "..."
Madoka: "..."
The other two, who lacked much of a foundation, were completely lost.
Madoka: "This feels harder than math. I don't understand it at all."
Madoka: "How about you, Rin-oneechan?"
Madoka: "@Rin Tohsaka."
Rin Tohsaka: "I only understood about twenty percent, but it's okay. I've already taken notes on the key points!"
For a lesson from a powerhouse even greater than the Second Magician, Rin Tohsaka approached it with a pious heart. Whether she understood it or not, she would write it down first!
This studious behavior immediately earned the respect of the two slackers.
Madoka: "Rin-oneechan is so amazing!"
Kanae: "So diligent. Little Rin will definitely become a powerhouse in the future."
Seeing their words of admiration, an embarrassed smile appeared on Rin's face.
Just as she was about to say a few modest words, she suddenly heard Su Mo's voice continue in the group live stream. She hurriedly switched her interface back, listening with full attention to the rest of the explanation.
"Understanding half is enough. Once you understand how the old technique is constructed, the method for optimization becomes clear at a glance."
Hearing Su Mo's words, the group members stared blankly, not understanding what was so "clear at a glance." They suddenly had the feeling of being in class, not understanding a thing, but being called on by the teacher to answer a question.
Fortunately, Su Mo wasn't asking a question. After his casual remark, he immediately provided the principle.
"Obviously, to change the technique's effect, one must precisely adjust the divine office the technique corresponds to. Here, we need to discard the broad divine office of 'protector of travelers' and enter its core: the power of 'boundaries and the crossing of boundaries'."
"In the Age of Gods, the borders between nations often represented the borders between different mythologies. In other words, they could represent the borders between divine realms. Hermes, being able to cross different borders, naturally possessed the power to traverse divine realms. And so-called divine realms are considered to be other dimensional spaces. Therefore, Hermes naturally possesses the power of dimensional leaps."
"And by replacing the core based on the previous technique's improvements..."
"In conclusion, the technique for a dimensional leap can be easily constructed."
With a self-taught, high-speed divine tongue, Su Mo laid out the entire core of the technique in an extremely short amount of time, holding nothing back.
"If you understood the principles I've explained, setting the others aside, Erica should be able to use the advanced version of the technique directly."
Saying this, Su Mo turned to the blonde girl who was lost in thought and asked, "Did you learn it?"
"..."
Erica, her eyes completely spun into spirals, forced a smile that wasn't too impolite.
Yep, I've learned how to be brain-dead.
