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

Within the two rising pillars of light, a dark purple dragon with the number 8 engraved beneath its feet roared instantly, and a mage wielding a staff and commanding the power of fusion appeared in an instant.

Upon seeing the monster's appearance, a hint of worry appeared on Yugo's face:

"Yuya, are you trying to summon [Heterochromatic Wind and Thunder Dragon]? But according to him, the effect of [Heterochromatic Wind and Thunder Dragon] shouldn't work on that [Parasitic Queen], right?"

"I know, so I'm not summoning [Heterochromatic Wind and Thunder Dragon], but another monster!"

Having said that, Yuya immediately raised his hand and announced,

"I activate the effect of [Entertainment Partner Odd-Eyes Fuder]! I fuse it with [Odd-Eyes Overlord Pendulum Dragon] from the Pendulum Zone as material!"

O dragon with heterochromatic eyes! Now, imbue your dragon power into this beastly form and embark on a new evolution! Fusion Summon! Level 8, [Heterochromatic Steelclaw Wolf]!

Within the white light of the two figures merging, a pair of sharp, long steel claws instantly tore through the light, revealing its werewolf body clad in gray steel armor.

However, the red scales and gray-white horny dragon wings on its armor, which are exactly the same as those on the [Heterochromatic Pendulum Dragon], clearly demonstrate the connection between the two.

As the [Odd-Eyes Overlord Pendulum Dragon] that served as the pendulum scale disappeared, the remaining pendulum beam on one side also dimmed instantly.

However, Yuya has another card in his hand that would be quite suitable as a pendulum scale:

"Now that the pendulum zone is empty, I'm setting the pendulum scale of [Supernova Dragon Odd-Eyes Revolution Dragon] with a scale of 12 in my hand!"

Covered in gunmetal gray armor, with three rings on its back and huge dragon wings outlined in gold, the dragon rose into the pillar of light, stepping on the number 12.

Perhaps it never imagined that it, which had always been sent to the graveyard in exchange for other cards, would one day step onto the dueling arena.

Although he's only staying in the backcourt for now.

"In this way, I can use Pendulum Summon monsters from Level 1 to Level 11! However, due to the effect of [Super New Dragon Odd-Eyes Revolution Dragon], I can only summon Dragon-type monsters."

With a flick of his wrist on the Duel Disk, Yuya quickly selected the monster he wanted to Pendulum Summon.

"Swing, Soul Pendulum! Draw arcs of light across the sky, Pendulum Summon! Come forth, my monsters! [Opposite-Eyes Pendulum Dragon], [Opposite-Eyes Phantom Dragon], and [Opposite-Eyes Overlord Pendulum Dragon]!"

Between the two pillars of light, the void of the Pendulum Summoning instantly opened, and red, blue, and purple orbs of light fell from it, transforming into dragons with corresponding colors on Yuya's field.

"Oh, oh, oh! It's here? The pendulum dragon!"

Upon hearing the sudden sound, Yuya turned his gaze toward the source of the voice, Yuri.

Thinking of his connection with Yuri and Yuri's purpose, Yuya silently raised his hand and began to chant again:

"Next, I will stack the level 7 [Opposite Eyes Pendulum Dragon] and [Opposite Eyes Tyrant Pendulum Dragon] on the field!"

The resolute soul, once again encased in the eyes of the heterochromatic eyes, now returns to freeze everything with unparalleled chill! Xyz Summon! Rank 7, [Odd-Eye Zero Dragon]!

As the chill dissipated, the ice dragon raised its head from the massive black hole, glaring menacingly at its enemy, the disgusting insect opposite it.

"Battle has begun! [Heterochromatic Steel Claw Wolf], attack [Parasitic Queen]! [Steel Wolf Twin Claw Slash Sword]!"

Upon hearing Yuya Sakaki's command, and seeing the [Heterochromatic Steel Claw Wolf] with 3000 attack power lunge at [Parasitic Queen] with its claws outstretched, the [Doctor] instinctively gave the order:

"[Parasitic Queen]'s effect! When an opponent's monster declares an attack, you can equip one of its equipped [Parasitic Fusion Bugs] to that attacking monster!"

At the doctor's voice, a [Parasitic Fusion Bug] clinging to the [Parasitic Queen] immediately flew out and stuck to the [Heterochromatic Steelclaw Wolf], causing the [Heterochromatic Steelclaw Wolf]'s attack power to drop to 2200 points.

To this, [the doctor] explained with a smug look:

"Hmph, while [Parasitic Queen] is on the field, every monster other than [Parasitic Fusion Bug] that is equipped with will lose 800 ATK! You're asking for it, hahahaha!"

"Is that so? Then I'll activate the effect of [Odd-Eyed Steel Claw Wolf]: This card can only be activated when it declares an attack! All monsters you control gain 300 ATK until the End Phase!"

The [Heterochromatic Steel Claw Wolf], with an instant attack power of 2200, has increased its attack power to 2500, just surpassing the [Parasitic Queen's] current 2400. Yuya then took the opportunity to taunt him, saying...

"How about that? Now, the [Heterochromatic Steel Claw Wolf]'s attack power surpasses that of the [Parasitic Queen]. Even if your [Parasitic Fusion Worm] can negate combat destruction, how many times can you do that?"

Upon hearing Yuya's words, the [Doctor]'s mind went blank for a moment. Yes, even with the card in his back row, it could only withstand one more battle destruction. It would be better to reduce the attack power of [Odd-Eyes Steel Claw Wolf] again, destroy it, and retrieve the [Parasitic Fusion Worm] from the graveyard.

Then, [the Doctor] spoke again:

"I activate the effect of [Parasitic Queen] once more! Equip [Parasitic Fusion Bug] on [Odd-Eyed Steelclaw Wolf]!"

As yet another [Parasitic Fusion Bug] attached itself to the body of the [Heterochromatic Steel Claw Wolf], further reducing its attack power to 1700 points, Yuya revealed a slight smile:

"Right now! I activate the effect of [Odd-Eyes Zero Dragon]! When either of your monsters declares an attack, remove 1 Xyz Material from this card, and negate that attack!"

Chapter 211 Doctor's Seal, The Vine Prison in the Wandering World

A chilling aura emanated from the [Odd-Eyed Zero Dragon], freezing the [Odd-Eyed Steel Claw Wolf]'s legs firmly to the ground, preventing it from attacking the [Parasitic Queen] with 1700 attack power against 2100 attack power.

And then Yuya's voice rang out:

"After that, based on the effect of [Odd-Eyes Zero Dragon], I can Special Summon 1 [Odd-Eyes] monster from my hand or Graveyard! I Special Summon [Odd-Eyes Tyrant Pendulum Dragon], which I just sent to the Graveyard as Xyz Material!"

In the path where the cold air gathered, light converged, and a dragon with a dark purple body, bound by silver-white chains, appeared on Yuya's field in this point of light.

"Then, for the second attack, [Odd-Eyed Tyrant Pendulum Dragon], attack [Parasitic Queen]!"

Now that he had realized what was happening, the [Doctor] looked at the [Odd-Eyed Tyrant Pendulum Dragon]'s 3000 attack power and knew that he could no longer equip the [Parasitic Fusion Bug] on Yuya's monster.

Otherwise, his [Parasitic Queen] would truly lose its ability to resist destruction.

Facing the purplish-black spiral beam of light emitted by [Odd-Eyes Tyrant Pendulum Dragon], [Parasitic Queen] took the hit head-on, and in the dust kicked up by the attack, [Doctor]'s LP dropped to 3100 points.

However, nowadays, there isn't a single Parasitic Fusion Worm on the [Parasitic Queen], and even her attack power has returned to a pitiful 1800 points.

But [the Doctor] then opened the card at his feet:

"I activate the Trap Card, [Enhanced Parasite]! I equip one [Parasitic Fusion] from my Graveyard as an Equip Spell Card that increases the ATK of [Parasitic Queen] on my field!"

Instantly, with [Parasitic Fusion Bug] back as an Equip Card, [Parasitic Queen]'s attack power quickly rebounded to 2400 points thanks to the combined effects of herself and the Trap Card.

However, this was still in vain.

"Next, [Heterochromatic Zero Dragon]'s attack, [Zero Charge]!"

Faced with this icy dragon charging towards them, enveloped in a chilling aura, the [Doctor] dared not equip it with the [Parasitic Fusion Bug]. After all, this would only reduce the [Odd-Eyed Zero Dragon's] attack power to 2300 points, which would still be enough to defeat the [Parasitic Queen], whose attack power was 1800 points.

Therefore, he had no choice but to sacrifice this [Parasitic Fusion Worm] and take the 700 points of damage.

As another [Parasitic Fusion Bug] flew out, taking the place of [Parasitic Queen] to withstand the icy charge, [Parasitic Queen]'s attack power dropped to 1800 points again.

And at that moment, Yuya Sakaki's voice rang out again:

"Finally, the [Heterochromatic Phantom Dragon] attacks! Defeat the [Parasitic Queen]! [Dream Spiral Flame]!"

Deep blue flames ignited in the mouth of the deep blue dragon clad in pale bone armor, forming a vortex of fire that engulfed the [Parasitic Queen].

This time, the Parasite Queen had no more Parasite Fusion Worms to shield her, and could only howl and explode in the flames.

Meanwhile, [Doctor's] LP dropped by 1000 points to 1400 points, but he laughed arrogantly:

"Hahahaha! It's not over yet. My turn has come. I'm going to punish all this suffering..."

"No, it's over!"

Yuya's roar instantly interrupted [the Doctor's] laughter. The Doctor's eyes widened as he saw Yuya raise his hand, speaking with a look of disgust.

"At this moment, the effect of [Odd-Eyes Phantom Dragon] activates! When this Pendulum Summoned card deals battle damage to your opponent, inflict damage to your opponent equal to 1200 points for each [Odd-Eyes] card in your Pendulum Zone!"

My [Odd-Eyed Phantom Dragon] and [Odd-Eyed Revolutionary Dragon] in my Pendulum Zone both have the [Odd-Eyed] trait! So, you disgusting creature, you'll have to take this 2400 damage along with Yuri! [Vision Power Atomic Power]!

A deep blue ripple instantly emanated from the [Odd-Eyed Phantom Dragon]. In the eyes of Yuri and the [Doctor], the two dragons in the Yuya Pendulum Zone had now completely transformed into the form of the [Odd-Eyed Phantom Dragon], opening their blood-red maws and spewing out blue-white spiral flames.

"Well……"

In an instant, Yuri's LP dropped from 4000 points to a precarious 1600 points, while [Doctor]'s LP was completely wiped out by this attack.

This scene is just like a replica of the moment at the beginning of the duel when [the professor] used [Ancient Machine Ultimate Hound] to reduce the LP of Yuya and Yugo.

The only difference was that as [Doctor]'s LP was reset to zero, the Duel Disk on his wrist also began to glow with a faint purple light.

Then, amidst a flash of purple light, the [Doctor]'s body vanished completely, leaving only a card bearing his terrified face, which was spat out by his Duel Disk and slowly floated to the ground.

At this moment, Yuya also ended his turn:

"Alright, I'll place the last two cards face down, and my turn is over. Your turn, Yuri!"

"Hmph, I don't need you to remind me! It's my turn, draw a card!"

Upon seeing the card he drew, Yuri's face instantly broke into a wicked grin, and he immediately sent the card into the Duel Disk.

"Looks like I've drawn a good card. I activate my Continuous Spell Card, [Capture Tsutsumi]! As long as this card is in the Spell & Trap Zone, the effects of all face-up cards on your opponent's field are negated! Your opponent's monsters cannot attack!"

Instantly, patches of dark green vines grew wildly in the laboratory, and soon they covered the entire laboratory, enclosing the group like a prison.

As the vines spread, the monsters on Yuya's field instantly weakened, and Yuya's expression turned grim. After being taught by Soleva, he clearly knew how overpowered this card was.

"Isn't this kind of card a bit too much?"

Upon hearing Yuya make that sound, Yuri immediately wagged her index finger with a sly smile and retorted:

"No, no, no, you must know that maintaining [Bound Tsutsuki Castle] also comes at a price. During my turn's preparation phase, I must release a [Predatory Plant] monster as a sacrifice, otherwise, [Bound Tsutsuki Castle] will be destroyed."

but……"

Deliberately drawing out the sound, Youli said, as if mocking,

"When [Capture the City] is destroyed, that might be the time of your defeat."

"you!"

Faced with Yuri's taunts, Yugo was about to retort when Yuya stopped him. This angered Yugo, causing him to feel a slight resentment towards Yuya.

"Why are you stopping me, Yuya!"

"Calm down, Yugo. No matter how angry you get, it won't change anything. Besides..."

Looking at the location where Yuu had placed the [Capture Tsuta Castle] card, and the locations of the two cards he had covered, Yuuya's face showed a slight smile.

"The outcome of this round is uncertain."

Chapter 212 Zack's Temptation

Despite hearing Yuya's words, Yuri didn't take them to heart at all. In his view, with all of Yuya's cards on the field, he couldn't activate any effects and couldn't possibly do anything.

"I Normal Summon [Predatory Plant Bee Orchid Scorpion] from my hand and activate its effect! When this card is Normal or Special Summoned, you can send one [Predatory Plant] monster from your hand to the Graveyard, and Special Summon one Level 3 or lower [Predatory Plant] monster from your Deck!"

I send [Pitcher Plant] from my hand to the Graveyard and Special Summon [Pitcher Plant Cobra] from my Deck!

In an instant, amidst two beams of white light, the two [Predatory Plant] monsters that Yuya and the others had seen Yuri summon during their previous confrontation instantly appeared on Yuri's field.

Yuri then activated the effect of [Snake Bottle Grass Cobra]:
