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

He and Yuya then firmly blocked the route that Yuri and the [Professor] could use to call for help from Ruri, and launched a duel against the two of them.

"Let's duel!" ×2

Yuri didn't take the challenges from Yuya and Yugo seriously. In his opinion, he could handle Yugo's situation just like last time, so he could handle it a second time. There was nothing to fear.

He could take this opportunity to absorb the two of them and become the real Zach.

Yuri readily accepted the duel.

"duel!"

As for the [Doctor] beside him, seeing that Yuri had accepted the duel, he immediately joined in as well, saying in a trembling voice:

"A...a duel!"

Ruri, who was controlled by the brainwashed parasite, wanted to come and help the two, but Yuto, who had received Yuya's message, stopped her with his Duel Disk:

"Ruri, defeat me in a duel, or I won't let you pass!"

"So……"

"Duel!" ×2

Chapter 203 The Birds Singing in the Abyss

"Then, it's my turn to go first! I activate the effect of [Lyrical Warbler - Turquoise Warbler] in my hand!"

With Yudou intentionally yielding, Ruri earned the right to go first, and she immediately revealed one of the monsters in her hand.

"When neither player has any monsters on the field, this card can be Special Summoned from their hand!"

In an instant, a female humanoid bird, dressed in a gray-green adventure suit and with turquoise and blue feathers, appeared in the light.

And Ruri's voice rang out again after the monster was successfully summoned:

"And when it is successfully Special Summoned, you can Special Summon a Level 1 [Lyrical Bird] monster from your hand! I'm summoning [Lyrical Bird - Cobalt Spinel]!"

Another card fell between Liuli's fingers. This time, the humanoid bird that appeared had feathers of three colors: off-white, brown, and dark brown. There were also several blue gems on its chest, making it look like a sapphire necklace hanging on its chest from a distance.

"When this card is Special Summoned, you can add one [Cobalt Spinel Sparrow] from your Deck to your hand."

As she spoke, Ruri caught another [Cobalt Spinel Sparrow] that popped out of her deck and added it to her hand. But then, Ruri flipped over a card next to [Cobalt Spinel Sparrow] in her hand:

"Next is the effect of [Lyrical Bird - Blue Swallow] in my hand! When you control a [Lyrical Bird] monster other than [Blue Swallow], you can Special Summon this card and another Level 1 [Lyrical Bird] monster from your hand!"

Come, [Blue Swallow]! And another [Cobalt Spinel]!

With both cards played simultaneously, two more monsters appeared on Ruri's field.

One was a bird exactly like the [Cobalt Spinel Finch] that had just appeared on the field, while the other was a humanoid bird with white and dark blue feathers, resembling a woman wearing a tailcoat, except that its collar was replaced by a cobalt blue gemstone.

"Now I have four Level 1 monsters on the field! I'll overlay my two Level 1 [Cobalt Spinel] monsters with one [Blue Swallow] and one [Turquoise Warbler]!"

Birds with beautiful wings! Gather on the battlefield and shine with elegance! Xyz Summon! Arrive gracefully! Tier 1, [Lyrical Robin - Gathering Nightingale]!

As Ruri opened her arms, the four humanoid birds on her field instantly transformed into green light and surged into the supermassive black hole. And within a pillar of light, the humanoid bird that had once inflicted such a profound psychological trauma on Yuya with its five-hit combo by Soreva arrived on Ruri's field.

Even Yuya, who had his back to Ruri and Yuto, got goosebumps when he heard Ruri's very familiar chanting.

Yudou was a little confused as to why Ruri would summon this monster.

"[Gathering Nightingales] gains 100 attack power for each supermaterial it has, and can launch a direct attack on the opposing player for that number of times."

However, it's your turn to attack first, so you can't attack at all. Don't you think that [Gathering Nightingale] with only 400 attack power is a bit too fragile for me in the next turn?

Upon hearing Yudou's words, Ruri simply smiled coldly and said:

"It seems you're quite familiar with my [Lyrical Crow] deck, but where's this card!?"

With that, Ruri took out a magic card from her last two cards and put it into her Duel Disk.

"I activate the Spell Card, [Parasitic Release]! You can Special Summon 1 [Parasitic Fusion] from your hand, Deck, or Graveyard! I Special Summon 1 [Parasitic Fusion] from my Deck!"

Amidst the surging of light spots, a creature covered in dark red carapace, with six hook-like claws wrapped in orbs of light, and a long green line protruding from its slender tail, instantly appeared in front of Liuli.

"When [Parasitic Fusion] is successfully Special Summoned, this card can be used as material to perform a Fusion Summon without using [Fusion]! And what I want to fuse is [Parasitic Fusion] and [Gathering Nightingale] on the field!"

"What!? Fusion Summoning!?"

Upon hearing Ruri's voice, Yuto was instantly surprised. Although he had a card in his hand that could stop this fusion summon, he still wanted to see what kind of monster Ruri, who was under brainwashing and control, would create.

"O little nightingale's song echoes in the darkness! Merge with your inner voice and let out a more stirring cry! Merge and summon! Come gracefully, elegant and proud nightingale! [Lyrical Robin - Solitary Nightingale]!"

As the two monsters merged into a beam of white light within the swirling vortex, feathers radiating pure white light burst forth from this light.

At the heart of these white feathers, a bird adorned with vibrant plumage of gold, red, and deep blue spread its wings and soared before Liuli. But soon, the [Parasitic Fusion Worm], which had just been used as fusion material, reappeared, binding its body tightly to the chest of the [Independent Nightingale].

The eyes of the [Independent Nightingale] also flashed a dangerous red light as the tentacles at the end of the [Parasitic Fusion Worm]'s tail rested on its head.

Liuli's voice rang out again at this moment:

"[Parasitic Fusion Bug] not only serves as a Fusion Material, but also becomes an Equip Card for the Fusion Monster! And then..."

As Ruri tapped her fingers on the Duel Disk panel, the [Independent Nightingale], which was originally only a Level 1 monster, suddenly rose to Level 4, becoming a Level 5 monster, and its attack power also jumped from 1000 to 3500.

"When [Independent Nightingale] is successfully fused, its level will increase by the number of Xyz Material [Gathering Nightingale] used as fusion material! In addition, its attack power will also increase by its own level × 500 points."

Next, I activate the other effect of [Independent Nightingale]! Once per turn during my Main Phase, inflict damage to your opponent equal to this card's Level x 500!

Emerald green light spots gathered on the wings of [Independent Nightingale] and eventually transformed into feathers of light that struck Yuto's side, instantly reducing Yuto's LP to 1500 points.

"Ha, is that all? You can't handle me then."

Faced with You Dou's provocation, Liu Li immediately frowned and revealed the last card in her hand:

"Don't forget, I haven't performed a Normal Summon this turn! I'm Tribute Summoning [Tyrant Neptune] from my hand! This card is a Level 10 monster, but it only needs to Tribute one monster on the field to be Tribute Summoned!"

Therefore, I sacrifice my [Independent Nightingale] to summon this [Tyrant Neptune]!

As the [Independent Nightingale]'s body dissipated into specks of light, a monster clad in heavy armor, standing on its hind legs, wielding a massive scythe, and with its head shrouded in shadow, resembling a giant crocodile-man, stood on the glass field amidst the shimmering water.

"When this card is successfully Tribute Summoned, you can take the effect of one Tributed Effect Monster from your Graveyard and use this card as the same card as that monster!"

Therefore, [Tyrant Neptune], seize the name and power of [Independent Nightingale]!

As Liuli's voice rang out, [Tyrant Neptune] immediately swung its scythe, and the phantom of [Independent Nightingale] appeared behind it. Liuli's next words caused the scythe in its hand to gradually glow brightly:

"Next, activate the ability of [Independent Nightingale] that [Tyrant Neptune] stole! Inflict damage equal to this card's Level x 500! Take this 5000 damage!"

Just as [Tyrant Neptune] was about to throw out the scythe, now infused with the phantom of [Independent Nightingale] and gleaming with white light, to finish off Yuto, Yuto no longer concealed himself and revealed the card in his hand:

"I activate a Trap Card from my hand, [Infinite Impermanence]!"

Chapter 204 The Rondo of Demons and Knights

"What!? A trap card activated from the hand!?"

As the illusion shattered, the phantom of the Independent Nightingale on Tyrant Neptune vanished, and the scythe in its hand instantly lost its gleam. Liuli let out a cry of surprise.

Yuto, however, said in a firm voice:

"That's right, this card can be activated from your hand even if you have no cards on your field! And the monsters targeted by this card have their effects negated until the end of the turn!"

Seeing the [Tyrant Neptune]'s attack power instantly drop back to 0, and her own empty hand, Liuli immediately said resentfully:

"End of round."

"Then, my turn, draw a card!"

Finally, after a series of close calls, it was his turn. Upon seeing the card that had come into his hand, Yudou immediately discarded it.

"I Normal Summon [The Guide to Death from the Demon World to the Mortal Realm] and activate its effect! When this card is successfully Summoned, you can Special Summon 1 Level 3 Fiend-Type monster from your hand or Deck by negating its effect!"

As the sound of the game began, a demonic female tour guide, dressed in a dark blue uniform, carrying a black bag with a silver skull logo, and with purplish-red hair, appeared instantly. She put a silver whistle in her mouth and blew it.

Amidst a piercing whistle, a jet-black train, its dim headlights outlining a demonic, malevolent gaze, sped past. Yuto announced the name of the monster he was summoning.

"I choose [Grapia Cane the Demon from the Other Shore] from my Special Summon deck!"

Suddenly, a monster resembling a hellhound with abnormally large forelimbs, forced to stand on its hind legs, leaped off the speeding train and onto the arena. Behind it, a pair of demonic wings unfurled, echoing the bright red "X" symbol on its chest.

As the monster arrived, Yuto immediately raised his hand and began to chant:

"Summoning conditions: two Level 3 monsters! I use my Level 3 monsters [Death Guide] and [Gravia Cane] on my field as Link Materials and set a Link Arrow! Link Summon! Link 2: [Cherubim the Dark Angel from Beyond]!"

The two monsters in the arena instantly transformed into two beams of red light, striking the lower left and lower right corners of the azure door that appeared out of thin air, completely illuminating the two bright red arrows.

The first thing to emerge from the azure door was a man with a dark face and hair that burned like flames. But beneath his face were two pairs of jet-black wings that intertwined like the hem of a garment.

Immediately afterwards, two pairs of thick arms emerged, along with a bull's head on the right arm and a lion's head on the left arm. In the right hand was a deep blue magic circle, and in the left hand was a dagger with a curved, crimson blade that resembled flames.

Finally, on the back of this dark angel, there is the head of a black swan, facing away from the crowd and looking up at the sky. Its outstretched wings are covered with patterns that look like golden eyes.

After the [Cherubim the Dark Angel from the Other Shore] fully appeared, Yuto tapped the Duel Disk with his finger, and the figure of [Graviacane], who had just entered the Graveyard, reappeared:

"Next, I activate the effect of [Grapiacane] in my Graveyard! When this card is sent to the Graveyard, you can Special Summon 1 [Other] monster from your Deck, except [Grapiacane]!"

Come, [Chiriato, the demon from the other side]!

[Graviacane]'s body instantly turned into specks of light, transforming on the arena into a gigantic pig-headed man with a jet-black body, a bloated build, and chains wrapped around his limbs.

And after [Chiriato] appeared, Yuto raised his hand again:

"Next, another Link Summon! Summoning conditions: two or more DARK monsters! I'll use [Cherubim] and [Chiriato], both Link 2 monsters on the field, as Link Materials and set Link Arrows!"

Amidst the sounds of the battle, the two red beams of light formed by [Cherubim] and the red beam of light formed by [Chiriato] struck the three arrows on the lower left, lower right, and right sides of the reappearing azure door, illuminating them.

A figure wielding a battle axe, clad in tattered armor with eerie flames constantly emanating from the gaps in the armor, slowly emerged from the doorway.

"Broken knight's spirit! Now, gather once more! Show your indomitable spirit to the enemy! Link Summon! Link 3, [Phantom Knights Rusty Moonblade Axe]!"

After loudly calling out the monster's name, Yuto pointed his finger again, and [Chiriato] reappeared, just like [Graviacane] had before.

"The effect of [Chiriato] in the Graveyard is activated! When this card is sent to the Graveyard, you can Special Summon 1 [Other] monster in your Graveyard, except this card!"

Return from death, [Cherubim, the dark angel from the other side]!

As the light converged, the [Cherubim] that had just served as a linking element reappeared on Yuto's field. Then, with a slight flick of his finger, the [Rusty Moonblade Axe] that had just appeared glowed with ghostly flames.

"Then, I activate the effect of [Rusty Moonblade Axe]! During my Main Phase, I can send one [Phantom Knights] monster from my Deck to the Graveyard and set one [Phantom] Spell/Trap Card from my Deck to my Spell/Trap Zone."

I sent one of my [Phantom Knights: Dusty Robes] cards to the Graveyard.

A card back then appeared in Yuto's back row, but it also disappeared quickly.
