The next day.
Professor Cronos announced the incident in front of the entire school faculty and students.
The school temporarily lost contact with the outside world. The school administration is striving to restore communication with the outside world. Before that, students are advised to stay within the Academy as much as possible, ideally remaining in the school buildings during the day and in dormitories at night to minimize risks.
Additionally, be cautious of classmates who inexplicably gather near you during external activities.
The school administration is working hard to develop and equip relevant protective measures. Students should remain vigilant until new devices are available.
Admittedly, with all the Duel Academy professors present worldwide, the Academy's research capabilities are indeed substantial. Just overnight, a professor specializing in "Virtual Image" technology discerned the basic logic of Spirits attacking humans and devised a design—a pair of single-lens transparent glasses mimicking X-Dimensional Duel Goggles, allowing effective differentiation between humans and Spirits, minimizing difficulties for students.
Tenjo Hikari tried them, and logically speaking, it's not the same as Hikari's "Psychological Observation Mirror," but instead aims to differentiate Spirit Power. Hence, it may not be entirely accurate, but it benefits from school resources support, allowing for rapid mass production.
Apart from the observation tools, the school administration also distributed Protective Artifacts to every student—these were mass-produced by Kaiba Company after students were attacked by Dark Elf Spirits at the Critical Point. They can be directly installed in Duel Disks to counter unexpected Spirit attacks.
Though they require seven to ten days for charging and each use is effective only once, they provide an added layer of protection, offering students a little more life safety.
Under Professor Cronos' arrangements, students gradually started to relax from their initial panic, and some even began to joke and laugh.
Academy itself is like an isolated island. Quite a few students came to Duel Academy to escape their families' nagging. Now, being completely "isolated from the outside world" seems kind of fun.
Still, some remain concerned.
If the Duel Academy lost contact with the outside world, would there be issues with food supply?
After all, with over a thousand people in the Academy, if food ran short, they wouldn't even need Spirit attacks; they would starve...
"Heh heh heh, no need to worry about that." Instructor Napoleon responded directly to the student's concern, "There won't be a shortage!"
No shortage?
The Duel Academy's supplies are primarily provided by Kaiba Company, usually arriving with new cards via air and sea to the Academy's "small shop"—actually the school's resource department.
Under normal circumstances, Duel Academy's food would suffice for students for about a month, but now with this lockdown, it's unclear how long it will last. Will it really be enough?
"Ho ho ho—student, you really worry too much about such matters!" Instructor Napoleon laughed, pulling over a seemingly friendly and low-profile teacher.
Some students hardly had any impression of this teacher.
But Tenjo Hikari knew this teacher well—his dorm head, Teacher Kabayama.
Although Tenjo Hikari had upgraded to Blue Academy, he still lived in Yellow Academy dormitory, not out of some sense of clinginess, but because Teacher Kabayama previously provided him much help, so Hikari couldn't just leave.
Including last night, Hikari followed Teacher Kabayama to find Yellow Academy students, leaving Blue Academy entirely to the newly arrived Ed—he was quite enthusiastic about it, despite his nonchalant words, deep down he liked helping others.
Teacher Kabayama is the dorm head of Yellow Academy and a home economics teacher at Duel Academy, usually responsible for teaching students cooking skills, being one of those teachers with little presence in a school primarily focused on teaching dueling.
However, as a teacher, he has his unique "talent."
Indeed—he's known as the "Curry Demon," a super curry fan.
Similar to Teacher Daitokuji's original Alchemy Deck, Teacher Kabayama also excels in the "Cooking Deck." His Curry Deck once made Kenzan sweat profusely in the original.
And in this Dimension, Teacher Kabayama has advanced even further, receiving the "Curry Demon's" Blessing, possessing the formidable ability to connect to the Curry Dimension using cards!
Thus—while he's around, there's virtually no chance of a "food shortage" happening.
Hence, even if the Academy's food ran out, everyone could still continue to consume curry as usual, eating for as long as they wish.
Although Tenjo Hikari isn't very fond of curry, he had spent some time dining in the Yellow Academy, so he didn't dislike curry. Besides, for Hikari, eating is just about being full.
Comparatively, most students are more concerned about the cutoff from the outside world, which hindered the usual delivery of new cards to Duel Academy.
Once the general situation is confirmed, the Academy staff, under Professor Cronos' arrangement, were divided into two groups: one continuing to provide services and courses to students—the internal affairs teachers; the other, led by Professor Cronos, responsible for exploring the current situation of the Academy, seeking all possible reasons to break the blockade and restore contact with the outside world.
