Is this the poker world?Ada thief!

Two flowers bloom, each telling its own story. Just as Hayato left the Duel Academy to search for his three lost dormitories, inside the Duel Academy—

"Unbelievable, this burst of energy throughout my body!" Jaden felt his body in astonishment, feeling an endless surge of energy. The discomfort left over from his duel with Professor Cobra was completely swept away, even though he had only taken a nap.

"Huh? It's already dark outside? Does that mean I slept from dawn until night?!"

"No, it's just because the time difference between this world and the human world we originally lived in is exactly twelve hours," Manjou pointed out. "Although it's dark outside now, it's actually only nine in the morning."

"I see." Judai scratched the back of his head and looked at Manjoume, who was lying on another bed made of tables and chairs, just like him. "But speaking of which, where did everyone else go? Why are you the only one left here, Manjoume?"

"I was also injured in the previous battles, you know. Although I didn't accumulate as much fatigue as you did after two consecutive duels, I still need to rest after one duel and being directly attacked by that golden guy." Manjoume raised an eyebrow and said unhappily, "What, is it bothering you that I'm resting here?"

"I didn't mean that~" Judai waved his hand, then remembered someone else, "But speaking of someone like you, Manjoume, John seems to be similar, he also went through a duel and was attacked by that guy."

“John Anderson from the North Campus? He went to help out at the school gate,” Misawa said calmly.

"Way!?" Judai and Manjoume exclaimed in unison, looking utterly startled. "Rokujo, when did you get here!?"

"First, it's not 60%, it's Misawa! Second, I've been here from the very beginning, okay? I even helped you tidy up this classroom last night so you could rest alone." Misawa looked annoyed, especially when he looked at Manjoume. "And Manjoume, you were already startled when you woke up, so why are you acting like you just found me now!"

"Who, who told you to have such a low profile? I completely forgot you were here!" When Manjoume heard Misawa say this, he awkwardly scratched his cheek, only then remembering that he had been startled by Misawa's sudden appearance when he first woke up, but he had forgotten about Misawa again as soon as he turned his head.

Getting out of bed, Judai put on a red dormitory jacket, then suddenly realized that it didn't seem to be her original one.

"Because you all had a long day out yesterday and encountered quite a few things, everyone's clothes are dirty. So Professor Chronos found some new clothes for you to change into from the warehouse. After all, none of you can go back to your dorms right now," Misawa explained, noticing Jaden's confusion. "Also, because we're in the desert, we need to conserve freshwater resources, so try to wear your clothes for as long as possible and don't get them dirty."

Manjoume nodded in agreement, saying, "That's right, that's right, I'm talking about you, Judai. Your clothes are covered in so much sand and dust, they're filthy."

(Manjoume, whose habits are quite terrible)
"No, I was actually talking about Manjoume. Judai's clothes look dusty but are actually quite clean. On the contrary, Manjoume, when are you going to get rid of your habit of wiping soy sauce on the table with your sleeves?" Misawa complained. "Auntie Tomie, who helps us take our old clothes to be washed, has complained that your clothes take three times more water than others."

"Urusai! My fighting power is three times that of those small fry, and my efficiency in solving problems and defeating enemies is also more than three times. So what if I use three times the water resources!" Manjou's red face spoke volumes. This guy was just being stubborn. "Anyway, I suddenly feel like I've rested enough and I'm going to get back to work!"

As he spoke, Manjoume grabbed a new uniform hanging on the back of his chair, got up, and walked out of the classroom.

"You're really efficient, Manjoume." Watching Manjoume run out, Jaden leisurely buttoned up his shirt one button at a time, then looked at Misawa and said, "By the way, Yoshino, are you going to continue resting here? Is it because the Duel Monsters outside are going to attack the academy and you were on guard duty last night?"

"If it's not four, then it's Misawa. Although the academy now has students forming patrol teams to defend against the dueling monsters that approach the academy from time to time, I actually didn't participate."

"Huh? This isn't like you at all?" Judai was a little surprised. Although Misawa was usually low-key, or to put it bluntly, he was not very noticeable, he was actually quite strong and had a strong sense of honor. Shouldn't he have volunteered to participate and protect the school with others when the school needed someone to step up?

"Of course I applied, but Professor Chronos and Hayato rejected my request, saying they didn't need another combatant like me, but I have irreplaceable importance in other aspects." Misawa spread his hands and picked up a small box from the side. "This is what I finished debugging last night—it feels strange to say this now because it's dark outside—while you were resting."

(In the original work, a long formula was written out, and in the end, he actually figured it out.)

"The special magnetic field in this world of card sprites interferes with most of the communication devices that can be used normally. When I first came to this world, I thought so, just like most people. But after carefully observing the changes in the magnetic field of this world, I found that it was not the case. In fact, the magnetic field of this world is only slightly different from that of the human world we originally came from, which is causing the interference."

"It is because of this special interference that does not exist in the human world but exists in all aspects of this world that the magnetic field changes in a way that affects all means of communication."

Upon hearing Misawa's words, Jaden immediately thought of the answer: "That 'special interference,' could it be 'duel energy'?"

Although Jaden and his friends were unaware of the existence of "Duel Energy" until yesterday, they only knew that the "Death Gloves" issued by Cobra Teacher could weaken and cause unconsciousness, and they had no idea about the specific principles behind it. However, Cobra Teacher himself repeatedly mentioned in the duel that he was collecting Duel Energy for that energy life form in order to achieve the "miracle" of reviving his adopted son. Jaden and his friends naturally learned about the existence of this energy and that it was born from the duels of duelists.

"Bingo!" Misawa nodded, gesturing for Judai to look at the small box he was holding. "I borrowed Jim Crocodile Cook's simple magnetic field device from the Southern Campus. By recording the changes in dueling energy at close range, I applied the Behnken formula to pinpoint the specific deviations that affected the magnetic field, and then calculated the result using the Stein formula." "I...I don't understand a word!" Judai felt like he was listening to gibberish, and his head started to ache. The comfortable feeling he had when he woke up was completely gone. It felt like he had slept for nothing last night, and he even felt more tired than when he fought three Cobra Professors. In the end, why did he talk so deeply about a topic that Misawa was interested in? Wasn't he just asking for trouble?

Misawa looked at Judai helplessly, then sighed: "I've tried my best to only talk about the theory and not explain the specific calculation process, so let me describe it in a different way. You can't be sixteen years old and still not have mastered calculus, can you?"

"Don't compare your brilliant mind to that of a slacker like me!" Judai quickly pleaded. "Mizawa, all you need to do is tell me what this is."

"You even called me by my name correctly just so you wouldn't listen to my explanation? Judai, you bastard!" Misawa complained helplessly, but still told Judai, "It's too time-consuming and labor-intensive to create a communication device that is not affected by duel energy from scratch, or to create a device that can maintain communication under the influence of duel energy. But it's still possible to create a device that can correct the influence of duel energy back to the normal magnetic field level."

"Although it's not completely successful yet, I've at least completed the preliminary experimental device, which is this thing. As long as it's attached to the terminal that the school has given to everyone with its own magnetic attachment, the terminal can regain some communication capabilities—but the specific anti-interference level still needs to be tested."

As he spoke, Misawa had already attached the box in his hand to his personal communication terminal. Judai watched as the signal bar in the upper right corner of the screen, which originally only had a red cross, actually displayed a signal strength after jumping a few times.

"As you can see, at least within the college, we can use the large-scale anti-interference device I completed in the lab as a relay station to keep everyone's terminals connected. Video calls are difficult, but text messaging is still possible."

As Misawa spoke, he complained, "There's always a subtle sense of disconnect. Is it because I'm used to the high-tech of the Haima Group? I almost forgot that it's only 2007. Apart from developed areas like Domino City, most people still communicate by texting."

However, the shortcomings that Misawa explained, such as "for use within the school" and "only for sending text messages," did not disappoint Jaden at all. He just excitedly put his hand on Misawa's shoulder and said, "You're amazing, Misawa! Are you some kind of Ultimate Inventor? You managed to develop such an incredible thing so quickly. You're so cool!"

“No, I’m not that much,” Misawa said, then hesitated for a moment, because he realized that Jaden had called his name correctly twice. “Yes, I am that much of a genius.”

It's not that he's shameless; if he can get people to keep calling him by the right name, then it doesn't seem so bad to shamelessly admit that he's a genius.

"Compared to when we could only communicate by shouting, Misawa's invention has really been a great help." Noticing that Misawa's eyes were a little dark, Jaden suddenly remembered that he had also come here to rest, and quickly got up to leave the classroom that had been specially prepared for them to rest. "You should rest well, Misawa. I think Professor Chronos and Hayato-sensei were right after all. More than participating in battles, your rich theoretical knowledge and outstanding mind are your greatest strengths, Misawa Sky!"

"So you only remembered the surname and not my first name? It's not Misawa Sky, it's Misawa Daichi! Give me back my gratitude—"

Before Misawa could finish speaking, Jaden had already closed the classroom door, shutting out the noise behind it. After all, Duel Academy was invested in by the Kaiba Group, and as everyone knows, Kaiba never considers cost-effectiveness when doing things; he only cares about the best, not whether it's expensive or not. When Duel Academy was built, the best materials and the best solutions were used, and the soundproofing was excellent, preventing the famous sayings like "Your classroom is the noisiest in the whole building" and "I could hear you arguing downstairs" from occurring at the source.

As soon as Jaden stepped out of the classroom, he saw two Obelisk Blue students running down the hallway. Judging from their appearance, they seemed to be first-year students. Although he had already been transported to another world and there was no longer a rule about "not running in the hallway," Jaden couldn't understand why they were in such a hurry. Didn't their middle school teachers teach them that?

Upon seeing Judai emerge from the classroom that served as a lounge, two students from the Obelisk-Blue dormitory immediately exclaimed, "You're Judai from the Red dormitory, right? Come and help us!"

"The school's warehouse has been attacked!"

"Huh? What do you mean the school's warehouse was attacked?" Upon hearing this, Jaden immediately became agitated and quickly caught up with the two of them. "Hey, explain yourself! What kind of things were stored in that warehouse?"

"In this world, what could be more precious than water and food? A food storage facility, of course!" one of them said. "Let's hurry and get there to check on things, or everyone at the school will be in trouble if they run out of food!"

Judai thought to himself, if the academy didn't have enough food, there would be an "external threat" of card spirits constantly attacking the academy, and an "internal worry" of restless hearts due to lack of food. It was indeed a very bad situation.

"But why not inform Hayato-sensei and the others—"

"That's because Principal Kobayashi Hayato—I mean, Principal Kobayashi Hayato—is not at school right now. He's gone to look for the students in the three missing dormitories. Professor Chronos is temporarily in charge of the school right now," said the boy with the green seaweed-like haircut.

“Besides, it’s too late to tell the teacher now. If we get there in time, maybe you, Judai-senpai, can catch the person who attacked the warehouse and protect everyone in the school!” Another boy said, his sideburns styled in a strange way.
