Traveling in reverse through the Yu-Gi-Oh! world with the MD system

Soleva's answer startled Zero. Then, Zero saw Soleva slide open the glass door of the wardrobe, which seemed a bit too big for the small room. But after the door slid open, there were no clothes inside. Instead, there was a small passageway leading to another glass sliding door.

Immediately afterwards, Soreva walked over and slid open the opposite sliding door. Only then did Zero realize that the bathroom in Soreva's room was hidden here, and only half of the wardrobe was used to store clothes.

With a bold step, Lingyi entered the wardrobe and saw that although there weren't many things in the bathroom, the most basic facilities and toiletries were all complete.

"awesome!"

With a cheer, Zero dashed into the bathroom, pushing Soreva out of the room.

"You, you go out for a moment. I, I want to use your bathroom to take a shower."

This reason prompted Soreva to immediately raise his hands in surrender:

"Yes, yes, I understand. Take your time washing. Just call me if you need anything."

After saying that, Soreva thoughtfully closed the bathroom door for her. Then, he went to his room to the computer whose progress was already at 40%.

"Alright, let's see what kind of world we're going to next."

Chapter 223 The Night Before Departure

"Ah, that feels so good!"

At this moment, Zero, who had finally emerged from the bathroom, had a completely satisfied expression on her face. Although the shower gel and shampoo from Soreva weren't the scents Zero was used to, they were enough for Zero, who was eager to take a bath.

After all, not taking a bath for more than ten years is unacceptable for any girl, and even a girl like Zero, who is willing to sacrifice herself to save the world, is no exception.

So, Zero, who had been unable to take a bath because she was only a soul and could not touch physical objects, immediately took a refreshing bath.

Even though she was a spirit, theoretically she shouldn't be able to get dusty, but psychologically, as a girl, Zero still felt a bit uncomfortable.

However, when she came out wearing the white shirt that Soreva had given her as temporary pajamas, she saw Soreva facing the computer with a worried look on his face.

"What's wrong? What's bothering you like this now?"

Hearing Zero's voice in his ear, Soreva was startled for a moment before quickly smiling and explaining:

"Don't worry, it's nothing serious. It's just that in the world we're going to next, some summoning methods and cards might not be usable anymore, so I'm wondering if I should adjust some of the deck's construction."

"That's it..."

Upon hearing Soreva's explanation, Zero immediately moved closer to Soreva, looked at the deck Soreva was holding, and asked curiously,

"Do you need my help? I'm quite a strong duelist myself, I'm sure I can be of assistance."

"This deck doesn't need replacing, since there are relatively few cards that need to be replaced in this deck. It's just that some cards from the Extra Deck need to be replaced..."

As she spoke, Soreva noticed that Zero's cheeks were puffed out in anger, so she quickly grabbed another card box from the table and handed it to Zero.

"Well, if you really want to help, Zero, then I'll have to ask you to adjust this deck. After all, I can't just use one deck all the time; sometimes I'll use different decks too."

For adjustments, just keep the cards suitable for Fusion Summoning and Xyz Summoning. If you need any additional cards, just ask me.

"it is good!"

She took the deck from Soreva and examined it carefully. Soon, Zero's brow furrowed.

"This deck... it seems difficult to perform Xyz Summons of the same rank without relying on the Field Spell Cards in this deck, right? So, Soleva, are the Link Monsters you included in this deck to ensure you can summon sufficiently powerful monsters even without this Field Spell Card?"

So, why make this adjustment?

Faced with a question like Zero's, Soreva simply shrugged and sighed helplessly.

"There's no other way. The world we're heading to next seems to only have two additional summoning methods: fusion and supersummoning. Although I can use other summoning methods with the help of that system, using them might cause trouble in that world."

"That's a bit troublesome indeed."

After giving a soft nod of agreement, Zero seemed to remember something and then turned to Soreva and asked,

"Then why did you expose your Link Summoning in our world? Weren't you afraid of getting into trouble back then?"

"That's because the circumstances are different!"

Turning his head, Soreva answered Zero's question as if it were perfectly natural.

"In your world, fusion, synchronization, and Xyz Summoning already exist, and with Yuya's creation of Pendulum Summoning as a precedent, you wouldn't have too many doubts if I presented a Link Summon, would you?"

There's a lot missing here. If I keep showing too many different summoning methods, people will get suspicious sooner or later.

"Ok."

Responding, Zero stopped asking questions and began adjusting her deck.

However, while calling it an adjustment, Zero felt that there was little need to change the core of Soreva's deck. After all, it wasn't a pendulum deck, and it already did a good enough job of supporting the deck's core features.

"So, does that mean this deck only needs some adjustments to the Extra Deck?"

After removing a bunch of Link Monsters used for support and add-ons, the Extra Deck of this deck suddenly had a lot of empty slots. Zero immediately picked out a few Xyz Monsters from this deck and added them in to increase the deck's core strength.

Even after seeing the effect of a Level 1 monster in this deck, she casually added the same-named card [Lyrical Nightingale - Gathering Nightingale] held by one of her clones, Ruri, to the Extra Deck.

Although she thought Soreva would use it more for another effect of the card, she wondered if he would actually use it and it might bring him some surprises.

"Then... if this deck can Xyz Summon Rank 7 monsters, adding this [Number 11 Giant Eye] might be useful."

However, just as Zero's finger found [No. 11 Giant Eye] and was about to add it to her Extra Deck, Soreva suddenly reached out and covered her palm, shaking his head at Zero with a wry smile:

"Sorry, Zero, I forgot to tell you earlier that some special [No.] cards can't be used, and this [No. 11 Giant Eye] is one of them."

"Eh? In that case..."

Setting down [No. 11 Giant Eye], Zero's fingers rummaged through the card pile again, and soon pulled out [No. 61 Volcano Dinosaur], displaying it to Soreva.

"How about this [No. 61 Volcanic Dinosaur]? This deck can also stack Rank 5 monsters, right!?"

"It's possible, but this [No. 61 Volcano Dinosaur] is a special card, the kind that can't be used."

"Well……"

Soleva's repeated refusal made Zero's cheeks puff up again in anger. At this moment, she understood why Soleva had been so troubled just now.

With this and that not allowed, what's the point of building this deck?

"What about this one? [Number 41 Mudstalker Baku]! Can I use this card?"

The two failures fueled Zero's stubbornness; she was determined to find a usable [No.] card. However, judging from Soreva's furrowed brow, it seemed she had failed again.

But the next second, the sound that came from Soreva's mouth instantly brought a smile to her face:

"This card... seems to work!"

"real!?"

Finally, Zero cheered after receiving a positive answer, and even threw herself onto Soreva to celebrate with him.

Filled with such joy, the two adjusted their decks countless times until sleepiness overcame them. Only then did they pack up their decks and card boxes, lie down on the bed together, and drift off to sleep.

........................

It must have been the second day. Having slept soundly and changed their clothes, Soreva and Zero stood at the door of the room.

"Then, let's go, Zero, let's welcome the new world."

As Soreva reached out and turned the doorknob, brilliant sunlight streamed in through the doorway.

Chapter 224 The AR Duel at Heart Garden, First Encounter with Yuma Tsukumo

"This place is called Heart Garden City..."

Walking through this technologically advanced city bathed in bright sunlight, Soreva couldn't help but sigh. The name "Heart Garden City" reminded him of Yuto and Hayabusa's hometown, which was also called "Heart Garden."

"If it weren't for the invasion and destruction by the [Academy], their [Heart Garden] would probably be a place as beautiful as this city."

Just as Soreva was feeling this way, he suddenly heard Zero's voice ring in his ear:

"Soreva, look over there."

Following the direction Zero was pointing, Soreva saw a group of people gathered together:

"Over there? There are quite a lot of people. Something must be going on. Is there anything special, Zero?"

"Hmm, over there, there should be a duel going on."

Upon hearing Zero's answer, Soreva immediately perked up. He was eager to see what duels were like in this world, so he quickly took Zero and walked over.

However, when he arrived, the scene there was somewhat disappointing.

The two people surrounded by the crowd were indeed holding duel disks, seemingly engaged in an extremely fierce duel, but...

"I can't see anything... How boring."

Looking around, Soreva saw that the spectators in the crowd all had extremely excited expressions, as if they could actually see the monsters fighting.

Although Soreva spoke softly enough that almost no one around him heard him, a chubby boy with dark green hair standing in front of him did hear him.

"Hey, sir, did you come to Heart Garden from somewhere else?"

Seeing the chubby boy turn to speak to him, Soreva's forehead veins bulged instantly. He said unhappily to the chubby boy, who seemed to be looking at him with a hint of disdain:

"Hey, chubby kid, who are you calling 'uncle'? I'm not even 30 yet!"

"Waaaah, I'm so sorry!"

Clearly, the chubby boy was also startled by Soreva's anger and quickly apologized to him.

However, at this moment, the commotion between the two seemed to have gotten a bit too big, and many of the onlookers cast angry glances at them, which frightened the chubby boy so much that he quickly pulled Soreva away.

"Hey, this is for you!"

Seeing the chubby boy who had dragged him across the street panting, Soreva sighed, bought a can of soda from a nearby vending machine, and tossed it to the boy.

The chubby boy, who was extremely thirsty after running all the way, hurriedly opened the soda and gulped it down several times before he felt better and had the strength to thank Soreva.

"Thank you, uncle!"

"I've already said I'm not even thirty yet! Can you please stop calling me 'uncle'?"

After angrily scaring the chubby boy again, Soreva asked him a question that had been bothering him for a while.

"By the way, how did you recognize that I came from somewhere else?"
