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

"When this card is Special Summoned, you can add one [Fusion] Spell Card from your Deck to your hand! And this time, the card I'm adding to my hand is [Super Polymerization]!"

Upon hearing that Yuri had chosen the [Super Fusion] card, Yugo's forehead instantly broke out in a cold sweat:

"Could it be that……"

"That's right, this time, I'm going to use your monsters as materials for a fusion summon!"

As if in a teasing manner, Yuri flashed the [Hyperfusion] in his hand and said smugly to the two of them,

"You might not know this, but the fusion materials required for my [Fierce Hungry Poison Fusion Dragon] are two DARK attribute monsters, so..."

Yugo immediately understood what Yuri hadn't said: all the monsters on Yuya's field right now—Odd-Eyes Phantom Dragon, Odd-Eyes Tyrant Pendulum Dragon, and Odd-Eyes Steel Claw Wolf—were, without exception, Dark-attribute monsters.

In other words, the game developers plan to use them as fusion materials.

Just then, Yuya also spoke up and asked Yuri:

"However, I have three DARK monsters on the field. Your [Hungry Poison Fusion Dragon] only needs two monsters as materials, right? So, which two monsters do you plan to use for fusion?"

Faced with this problem, Yuri sent the [Super Polymerization] card in her hand, along with another card, to the graveyard:

"I discard [Predatory Flowerpot] from my hand and activate [Super Polymerization]! I will use [Opposite Eyes Phantom Dragon] and [Opposite Eyes Tyrant Pendulum Dragon] on your field as materials to Fusion Summon!"

Two beasts wielding the power of endless darkness! Now merge into one, and a new threat will be born from the depths of hell! Fusion Summon! Appear, poisonous dragon with fangs of hunger! Level 8, [Ferocious Hungry Poison Fusion Dragon]!

A dark cloud, accompanied by lightning, appeared in the cramped laboratory, and the two dragon beasts on Yuya Field were instantly sucked into the dark cloud.

As their figures twisted and merged, finally, the ferocious poisonous dragon they had seen that day, symbolizing the summoning of fusion, poked its head out from the black clouds.

"Next, you should understand, right? When [Ferocious Hungry Poison Fusion Dragon] is successfully Fusion Summoned using only monsters on the field, its ATK increases by the sum of the ATKs of all monsters Special Summoned by your opponent until the end of the turn!"

As he spoke, Yuri pointed to the [Entertainment Partner Odd-Eyes Steel Claw Wolf] and [Odd-Eyes Zero Dragon] on the field, whose attack power was currently 3300 and 3100 respectively.

"Therefore, the [Fierce Hungry Poison Fusion Dragon]'s attack power has increased by 6300 points, for a total of 9100 points!"

As the purple light converged, the [Fierce Hungry Poison Fusion Dragon]'s attack power soared to 9100 points. A dangerous smile instantly spread across Youli's face.

"[Ferocious Hungry Poison Fusion Dragon], now, attack [Heterochromatic Steel Claw Wolf]!"

"Now! I activate my trap card, [Infinite Impermanence]!"

As the sound of Yuri launching her attack rang out, Yuya's voice followed. At his feet, a trap card had already been activated.

"This card can be activated by targeting 1 face-up monster your opponent controls; negate that monster's effects until the end of the turn! Also, when this Set card is activated, negate the effects of other Spell/Trap Cards in the same column as this card!"

I choose to negate the effect of your [Hungry Poison Fusion Dragon]! Furthermore, since your [Captured Castle] is in the same column as my [Infinite Bubble], its effect will also be negated!

Upon hearing Yuya's voice, Yuri immediately let out a disdainful sneer:

"Fool! With my [Capture Tsukuyomi Castle] here, even if you activate this card, its effect will still be negated!"

"I know, but don't forget, I have a second face-down card on the field!"

Yuya's response instantly widened Yuri's eyes, but at that moment, he could only watch helplessly as Yuya activated another card lying face down at his feet.

"Quick-Play Spell, [Forbidden Drop] activated! This card can only be activated by sending any number of cards other than this card from your hand or field to the Graveyard! And I can choose to negate the effects of that number of monsters my opponent controls, and their ATK is halved!"

Although this card's effect cannot be activated due to the presence of [Capture Tsuta Castle], I can send [Infinite Impermanence] and [Odd-Eyes Zero Dragon] from my field to the Graveyard!

In an instant, the newly revealed [Infinite Bubble] and the Ice Dragon on Yuya's field both turned into specks of light and dissipated on the field.

At that moment, Yuya's voice rang clearly in Yuri's ears:

"In this way, the effect of [Infinite Bubble] in the graveyard will not be negated by [Captured Tsutsumi]!"

In an instant, countless rainbow bubbles rose into the air. However, as the rainbow bubbles drifted away, the purple light on the [Fierce Hungry Poison Fusion Dragon] vanished instantly, and its attack power plummeted back to 2800 points.

Meanwhile, the vines that coiled around the laboratory, exuding a black aura, continued to emanate a strong sense of darkness, constantly shrouding the laboratory in a feeling of fear.

However, Yuri didn't understand why, if Sakaki Yuya wanted to successfully activate the effect of [Infinite Bubble], simply sending [Infinite Bubble] to the graveyard would have been enough. Why did he also send [Odd-Eyes Zero Dragon] to the graveyard?

Of course, if Yuya were the only one troubling himself at that moment, he probably wouldn't be so puzzled.

"Oh no, [Infinite Bubble] in the graveyard can't negate [Bound Tsutsumi]? Even if I use the effect of [Odd-Eyes Zero Dragon] to Special Summon [Odd-Eyes Wind and Thunder Dragon], its effect will just be negated, so it won't do any good at all! What should I do to clear all the monsters on his field, or destroy that [Bound Tsutsumi]?"

Just as Yuya was in such distress, Zack's voice rang in his mind:

"Although there's no way to destroy that [Capture Tsukuyomi], I do have a way to destroy the monsters on his field, and even win. Don't you want to give it a try?"

As he spoke, Yuya saw Zack appear in front of him, holding a card in his hand.

A card called [Overlord Purple Dragon Heterochromatic Viper].

"One of the effects of this card is that when it is destroyed, it can be swapped with a card in the Pendulum Zone to Special Summon the card in the Pendulum Zone and place this card in the Pendulum Zone."

Then, destroy all the monsters on your opponent's field and inflict damage equal to the destroyed monsters' ATK. That's how they lose.

Chapter 213 The Overlord's Purple Dragon

"You're right. In fact, the effect of [Overlord Purple Dragon Odd-Eyes Poison Dragon] after it's destroyed is activated in the Extra Deck, so it can't be negated by [Capture Tsuta Castle]. Therefore, Yuri is indeed doomed to lose. But..."

Changing the subject abruptly, Yuya instantly cast a suspicious glance at Zack in front of him.

"Why do you think I'd believe you're helping me? Back in the Synchro Dimension containment facility, you repeatedly tempted me to use your cards, trying to take advantage of me and possess my body. How do I know you're not doing the same thing this time?"

Faced with Yuya's questioning, Zack moved closer to Yuya as if they were old friends, and put his arm around Yuya's shoulder:

“I know you’re still angry about how I tried to take over your body back then, and I understand why you don’t trust me. So, I’ll give you a reason to trust me.”

"reason?"

Seeing the doubt in Yuya's eyes, Zack in front of Yuya immediately nodded:

"That's right! You also know that all four of you are my clones, Zack's alter egos, and that my power and consciousness reside in your bodies, right?"

Yuya nodded in agreement.

"Yes, I know, but what does that have to do with the reason you're trying to give?"

"Of course it matters!"

Instantly, Zack's voice rose several octaves as he spoke.

"Although we are all clones of Zack, I am different from the other three. They are now just chaotic consciousnesses with destructive desires, while I am a rational consciousness with my own will."

That's why I don't want you to lose and cause me to be assimilated by those irrational lunatics! Besides, even though we're all Zack's consciousness, I'm more rational than them; I should be the dominant consciousness of the resurrected Zack!

"So, your purpose in helping me is to make myself the dominant consciousness of Zack?"

He muttered something to himself, and Yuya instantly cast a sharp glance at Zack.

"But if you want to become Zack, you still have to take over my body, don't you?"

"That's not necessarily true now."

Zack's voice startled Yuya for a moment, but he quickly realized the hidden purpose behind Zack's words:

"You... have set your sights on Yuri, Yugo, and Yuto?"

"To be precise, it's that guy named Yuri."

After confirming Yuya's guess and revealing his true goal, Zack smiled and explained his plans.

"As long as you use my [Tyrant Purple Dragon Heterochromatic Viper Dragon] to defeat that guy named Yuri, it's equivalent to my power breaking the Zack power within him. I can also use this to invade his body, seize the Zack power within him, and be reborn as the real Zack."

"This……"

Upon hearing Zack's plan, Yuya was instantly horrified. In his view, this method of taking over other people's bodies and grinding away their original souls was rather cruel.

Zack clearly noticed Yuya's hesitation and said:

"Aren't you going to do anything? Then, can you summon other monsters to deal with this situation? If not, then you, and that Zack clone next to you named Yugo, will be constantly restricted by the effect of [Capture Tsutsumi], and you will most likely lose to that Yuri."

"By then, having devoured you and collected three-quarters of Zack's power, dealing with that last Zack clone will likely be a piece of cake. Then, a Zack dominated by him will be born, and the home you so desperately want to protect might very well be destroyed by his hand."

In an instant, Yuya fell silent. He had to admit that Zack was right. Under the restrictions of [Bound Tsutsumi Castle], he and Yugo had almost no chance of winning.

As for someone like Yuri... a complete Zack dominated by the Zack within him would probably only destroy this world composed of four dimensions.

At that moment, Yuya made up his mind: he absolutely could not let this happen!

However, he still harbored some reservations about Zack:

"But how can you guarantee that you won't destroy this world after you're reborn as Zack? And if you want to become Zack again, you'll need to absorb Zack's power from Yugo and Yuto, right? That way, you'll kill them too!"

Upon hearing Yuya's question, Zack's lips curled into a smile. He knew that Yuya's question proved that he also admitted he couldn't break Yuri's situation and was willing to use Zack's combined effects with [Overlord Purple Dragon Heterochromatic Poison Dragon].

However, he still harbored some distrust in his heart.

So, Zack immediately responded to Yuya with a smile:

"Yuya, you should know that I am the most special individual among the four of us, the only one with rationality. Therefore, I am different from the others, and I have many desires in addition to the desire for destruction, such as the pursuit of delicious food and the pursuit of the pleasure of dueling."

These desires were given to me by this world and its people, so I won't be like those others who, after being reborn, only knew how to destroy.

"As for the other two clones of Zach..."

In response, Zack simply shrugged and said,

"Actually, I just want to have a body that truly belongs to me. As for whether it's a complete Zack... I don't mind. In fact, it might be better if it's not complete."

After all, what if becoming the complete Zack erases my own consciousness?

"So, you're not going to make a move against Yudou and Yuwu?"

Upon hearing Yuya's concern, Zack immediately grinned:

"of course not."

"So, Zach..."

Slowly raising his hand, Yuya's determined gaze fell upon Zack.

"Lend me your power and that of [Tyrant Purple Dragon Heterochromatic Poison Dragon]."

In response, Zack placed the hand holding the [Tyrannosaurus Rex Heterochromatic Viper] into Yuya's palm:

"take it!"

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

Back in reality, Yuri only heard Yuya's voice suddenly ring out after a moment of dazed disorientation:

"I activate the effect of [Odd-Eyes Zero Dragon] in my Graveyard! When this Xyz Summoned card is sent to the Graveyard, you can Special Summon 1 [Odd-Eyes] monster other than [Odd-Eyes Zero Dragon] from your Extra Deck!"

Come forth, [Overlord Purple Dragon, Heterochromatic-Eyed Venomous Dragon]!
