Roxy stared wide-eyed at Dan Feng's actions, utterly shocked inside.
"The speed of a magic circle can actually be changed?" she asked in disbelief.
Dan Feng glanced at her expressionlessly, seemingly unsurprised by her astonishment, and calmly explained: "Of course it can. Perhaps you haven't reached this part in your studies yet. In the book written by Bloody Kant, it was once mentioned that magic circles are actually similar to magic spells—they can have their release speed altered through certain techniques."
After speaking, Dan Feng unhesitatingly used his own mana to instantly deactivate the magic circle that had been continuously spitting out water orbs.
The entire process was clean and decisive, without the slightest drag—looking just like the work of someone extremely experienced.
At this moment, Roxy's water-blue eyes were filled with admiration for Dan Feng. "That's so amazing, Dan Feng! You clearly haven't practiced this hands-on, yet you can do it so effortlessly just based on theoretical knowledge—it's incredible!"
Dan Feng showed little reaction to Roxy's praise, simply replying calmly: "This really doesn't require much practice. You just need to master some basic contract text." With that, he handed the pen back to Roxy.
Roxy happily accepted the pen. She quickly took out another sheet of paper, carefully placed it on the ground, dipped it in ink, and prepared to try drawing the magic circle again.
"Rewrite speed, base set to 0." Roxy murmured softly under her breath. The pen in her hand seemed to come alive, dancing rapidly across the paper.
Though this was only her second attempt, her exceptional talent ensured there was no hesitation or stumbling in the process—everything flowed naturally and smoothly.
Not long after, Roxy successfully completed her own version of the water-orb machine gun. The water orbs poured out from the magic circle without pause, just like bullets.
"I learned it! This is so amazing!" Roxy stared excitedly at the magic circle she had just drawn, her eyes shining even brighter than when she had first succeeded earlier.
The effect of this magic circle was identical to the one Dan Feng had drawn, filling her with immense pride.
As long as she could reach the same level as Dan Feng, she would feel this sense of accomplishment.
Dan Feng, watching from the side, let the corners of his mouth lift slightly as he said softly, "Congratulations."
Though his voice was calm, the words carried clear appreciation for Roxy.
Roxy was completely absorbed in her achievement, so much so that she hadn't noticed how quickly time had passed.
It wasn't until her stomach let out a loud rumble that she realized it was already noon—and she had been so focused on studying that she had completely forgotten to eat.
"It's already noon. Let's go grab some food at the cafeteria first." Roxy said somewhat sheepishly as she rubbed her stomach, turning to Dan Feng.
Dan Feng nodded. "Sure."
The two of them stood up and headed together toward the cafeteria.
Once inside, they didn't hesitate at all and went straight to the second floor.
They had eaten on both the first and second floors before and, after comparison, found that although the food on the second floor was relatively more expensive, it tasted several times better than the first floor.
So now, whenever they came to the cafeteria, they went directly to the second floor.
It had to be said—Ranoa Magic University, being a renowned institution, had a cafeteria of impressive scale and variety.
The food offered here was abundant and diverse, covering all kinds of cuisines and flavors.
Perhaps because the school had students from the Demon race and Beast race, most dishes included meat and came in very generous portions—more than enough to satisfy the students' needs.
After eating their fill, both Dan Feng and Roxy felt a little stuffed.
With nothing else pressing to do for the moment, they decided to head back to the library and continue exploring the sea of knowledge.
Dan Feng wanted to increase his progress bar, while Roxy wanted to improve herself.
Roxy was hoping to find some academic books that could help her abilities surpass others.
Here, Dan Feng and Roxy did not walk shoulder to shoulder—because at 145 cm tall, Roxy was simply too short. Even with her ahoge standing straight up, she barely reached Dan Feng's shoulder.
This combination of theirs was far too eye-catching as they walked along the path, causing many students to frequently turn their heads.
Dan Feng's expressionless yet strikingly handsome face, combined with the adorable-looking little girl beside him, led some people to misunderstand their current relationship.
Some of the female students, seeing the girl next to Dan Feng, refrained from approaching to strike up a conversation—after all, the overall quality of students admitted to Ranoa Magic University was still quite decent, aside from a few spoiled noble brats.
Upon arriving at the library once again, the two gradually quieted down. Then, at Roxy's request for Dan Feng to help her look for academic books together, Dan Feng agreed.
They walked together into the section filled with shelves of academic books. This area undoubtedly held the largest collection of books in the world—some shelves were so tall that ladders were required to reach the upper levels.
"What kind of academic books are you looking for?" Dan Feng asked Roxy.
"Magic-related ones would be good. If there are any on Saint-rank magic, that would be even better." Roxy thought for a moment and gave her answer.
"Saint-rank?" Dan Feng paused. He had been coming to the library for several days now, but he hadn't specifically looked for books on Saint-rank magic. Instead, he had spent his time reading history or geography-related books every day.
Roxy's reminder suddenly jogged his memory—Ranoa Magic University's library did indeed seem to contain theses on Saint-rank magic.
So Dan Feng began searching the shelves.
Roxy handled the lower rows, while Dan Feng took care of the upper ones.
While Roxy was still slowly browsing, Dan Feng had already quickly scanned through several rows. At this moment, he stood on a ladder, looking at the titles on the topmost shelves.
After some time spent searching, Roxy let out a delighted cry: "I found it!" With that, the two of them finished their search.
Dan Feng slowly climbed down from the ladder and looked at the book in Roxy's hand.
"Water Saint-Rank Magic: Thundercloud Accumulation Thesis, author Jinas?" Dan Feng slowly read the title aloud.
"A thesis on Water Saint-rank magic! If I study it seriously, I might even be able to learn Water Saint-rank magic." Roxy eagerly flipped open the first page.
Theses like this weren't easy to understand without sufficient knowledge. Even now, Roxy felt a bit lost and confused by what she was reading.
"Ugh, why is this written so complicated? It even explains the human mana circuit in detail." Roxy looked at the text on the first page and felt her head spinning.
"The first page is mostly listing the prerequisites for learning Water Saint-rank magic. Look—he clearly wrote here about mana capacity testing. It seems magic above Saint-rank consumes a huge amount." Dan Feng said slowly.
Then, giving Roxy a "leave it to me" look, he took the Water Saint-Rank Magic: Thundercloud Accumulation thesis from her hands.
This Jinas was quite the figure—to write such a thick book just for a Saint-rank magic thesis.
