High School of Demon Hunting

Discussing time and dimensions unexpectedly allowed Zheng Qing to break free from the slightly mundane study and troubles of these days, and regain a sense of truly being a university student.

He suddenly somewhat understood why First University eventually became the place with the highest concentration of Alliance high-level wizards.

This clean and pure feeling, outside the school gates, may never be found again.

Thinking that graduation is less than two months away, the young cost student can’t help but feel a bit regretful and somewhat nervous.

Until the weekend.

Before the evening class meeting.

The few young wizards occasionally discussed the issues of dimensions and time, except the number of participants expanded as the discussion location changed, with Zhang Ji Xin and Jiang Yu also joining besides the three warlocks from dorm 403.

Perhaps because graduation is in two months, Jiang Yu’s style now became somewhat ’bold’—just like tonight’s class meeting, she didn’t sit in the first row of the classroom as usual but rather naturally pushed Xiao Xiao away and sat beside Zheng Qing.

Poor Doctor Xiao, after nearly two years of enrollment, for the first time left his comfort zone, forced to share a desk with Li Meng, who was always critical of him since the beginning.

The good news is, he’s still sitting in the last few rows, albeit separated from Zheng Qing by an aisle.

The bad news is, without a familiar face next to him, he became somewhat isolated.

"Doesn’t it matter?"

Zheng Qing ignored the doctoral student’s pleading eyes, looked at the witch with concern, and carefully reminded: "Doctor can’t keep an eye on Li Meng... you put him next to Li Meng, it’s as if you’re giving Li Meng a holiday."

"She’s a college student, eventually, she has to continue her studies alone."

Jiang Yu gracefully bypassed this topic: "We’re graduating at the end of June. We can’t be watching her every day after graduation... Do you know what I thought of when you just talked about dimension unfolding?"

She subtly turned the topic back around.

"What?"

"That stick figure," the witch supported her chin with one hand, the feather pen between her fingers twirled lightly, pointing to the crude white paper behind the door.

Zheng Qing squinted his eyes instinctively.

A diagram, a picture, a standard two-dimensional environment, a special two-dimensional life.

"...I haven’t experienced a real two-dimensional world, but I imagine it would be very different from our world." The witch’s calm voice continued beside his ear: "But looking at that stick figure, I can’t help but wonder, if a symbol drawn on a plane makes a sound, does that count as a ’three-dimensional’ life form?"

"Two-dimensional," Zheng Qing couldn’t help but interject.

"No, it’s three-dimensional."

The witch fluttered her large eyes at him, her tone particularly serious: "Besides length and width, its life also possesses its unique ’height’—I mean the length of its sound—according to this logic, does the length of its life depend on the length it makes sound? Then what dimensions does the paper that accommodates its existence qualify as? Similarly, the portraits on the school teaching building walls, The Door God, etc., are they two-dimensional life or three-dimensional life?"

"Three-dimensional? No, wait, still two-dimensional... Seems not right." Zheng Qing was immediately drawn to this new perspective, wanted to analyze but found himself at a loss.

"Wait... According to your logic, what dimension do we wizards qualify as?" Xin Fat Man looked curiously at the witch.

"I don’t know."

Jiang Yu honestly shook her head: "It’s just because I don’t know, so I brought it up for discussion with you... Do you think that stick figure knows its properties?"

"A guy whose brain location can’t even be seen, how could it possibly understand such profound magic theories?" Even Zhang Ji Xin was skeptical about the witch’s ideas.

The four exchanged looks, and simultaneously looked towards Doctor Xiao on the other side of the aisle.

The doctor apparently wasn’t over the unhappiness of being forced away from his place, his head turned away pretending not to see his companions’ gazes.

But soon, he couldn’t resist, turned back, and joined the new discussion: "—The dimension wizards possess still hasn’t reached a unified saying. Some say it’s 9+1 dimensions, some say 13 dimensions, others say 10+1, or 9+2 dimensions, etc., these all depend on the different states a wizard finds themselves in... According to the most widely accepted Thompson model, the stick figure behind the door indeed doesn’t belong to a standard two-dimensional or three-dimensional life form, we can understand it as ’2+1’ dimensional life, two-dimensional is its basic attribute, and that extra dimension is its sound dimension. As for the three-dimensional world or three-dimensional life we commonly accept, that’s only a special concept in magic theory, almost nonexistent in reality."

This indeed was quite a clever approach.

"Sounds a bit like ’rational man’ concept," Zheng Qing mused.

"What rational man?"

"The economic concept of White Ding," the young man briefly explained: "Usually, there are too many variables natural people possess, inconvenient for summarization and research, so White Ding abstract a body possessing only basic characteristics by reducing natural human’s variables to construct theories... Using magic language to summarize, it’s ’All things can be converged’."

These last six words quieted this corner for a few seconds.

Then Xin Fat Man broke the silence again.

"What was that ’Thompson model’ you just mentioned," he blinked his small eyes, struggling to recall: "Why do I feel like I’ve heard it somewhere?"

"In last semester’s ’Magic Universe Study,’ the concept was mentioned," Doctor Xiao’s tone was faint as he complained: "Even though it’s an elective, even though you copied my homework all the time, you still earned credits, you shouldn’t have no impression at all!"

"Of course I have an impression! It’s just, just..." The Fat Wizard’s face turned red.

"Simply put, it’s that three-dimensional space and four-dimensional space aren’t ’nested’ relationships but ’coexisting’ status. Like in our living world, since two dimensions and three dimensions can coexist in one world, there’s no reason why four-dimensional or higher dimensions couldn’t exist in this world. It’s just limited by perception that we can’t detect other dimensions."

Jiang Yu spoke up to explain that problem for the Fat Wizard, noticing others’ gazes, she rarely stuck her tongue out, showing an embarrassed look: "I’ve only previewed this much... Teacher hasn’t yet talked about it."

Zheng Qing quietly breathed a sigh of relief.

Almost exposed his lack.

This semester he and Jiang Yu took ’Magic Universe Study’ together as an elective, so when Xiao Xiao complained, he also tried recalling the contents he learned but found nothing. Hearing Jiang Yu speak just now, he almost went to fetch his lecture notes.
