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

Seeing that even with the enhancement card he gave him, the shark still summoned [Submarine Carrier Shark] on the first move, Soreva's lips twitched involuntarily:

"This guy, hasn't he improved at all? Why is his first move still the same old thing... Uh, right, his animated version of [Aviation Shark] is indeed effective as a first move."

However, he now even knows how to use [Left-Handed Shark] to apply effect penetration resistance to [Airplane Shark], which is a bit of progress. And…”

Glancing at the shark's opponent, IV, Soreva couldn't help but twitch his lips.

"Speaking of which, many of the monsters in Series IV seem to rely on effect destruction, right? This is a good way to counter him, this is going to be tough—"

As for the shark, it naturally activated the [Aviation Shark] effect at this moment:

"Now, I activate the effect of [Aviation Shark]! Once per turn, this card can remove one Xyz Material and inflict damage to your opponent equal to 400 times the number of cards in your hand!"

With that, the shark revealed its last remaining cards.

"Now, I have 3 cards in my hand! So, IV, take this 1200 damage! [Aerial Torpedo]!"

As three torpedoes were launched by [Aviation Shark] towards IV, IV was blown away in the explosion, and his LP was reduced from 4000 points to 2800 points.

This scene not only elicited cheers from the spectators outside the arena, but even the star-studded spectators inside couldn't help but nod in approval:

"That was a really brilliant move."

The shark then immediately drew two cards from its hand and placed them face down:

"Finally, I set two cards face down, and the turn ends."

"Well done, shark! That's exactly why you're worth killing!"

His face once again contorted with near-madness, and IV's fingers reached towards his deck.

"My turn, draw a card!"

After the usual card draw, IV quickly revealed a card in his hand:

"When I have no monsters on my field and you have an Xyz Monster on your field, [Genius Puppet - Magnet Doll] (original) can be Special Summoned from my hand!"

As the card fell, a puppet with a grayish-green body, except for its yellow joints, and covered in what appeared to be bloodstains and unidentified dirt, appeared on the field of IV.

After the [Magnetic Doll] appeared, IV quickly added another card to his D panel:

"I will Normal Summon [Gearbox] from my hand! Once per turn, this card can be upgraded to the same Level as one [Gearbox] monster you control!"

Upgrade, [Gear Shifter]! Become Level 8, just like [Magnetic Doll]!

As [Gear Shifter] pushed the gear lever on its head, its level immediately became the same as [Magnetic Doll]'s level 8.

Thus, IV also began its own declaration:

"Now, I'll also stack my Level 8 [Gear Shifter] and [Magnetic Puppet]! I'll build a stacking network with two monsters! Xyz Summon!"

Appear! [No. 15]! Messenger from hell, puppet on the strings of fate! [Machine Puppet - Giant Slayer] (Original)!

Seeing the pitch-black giant appear on IV's field, and knowing that IV's purpose was to free the shark from the control of [No.] card, Soreva couldn't help but slap himself across the face:

"Damn it, I forgot to tell him the effect of the buff card I gave the shark. No wonder he summoned this monster!"

Chapter 445 The Shark Dragon is Born!

As expected, immediately after [No.15 Mechanical Puppet - Giant Slayer] appeared, IV activated its effect:

"Now, [Giant Slayer]'s effect activates! Remove one of its Xyz Materials, destroy all other Xyz Monsters on the field except this card! And inflict damage to the LP of each of those monster controllers equal to the total ATK of the destroyed monsters!"

Seeing the threads fired by [Giant Slayer] entangle [Aviation Shark], IV immediately grinned maliciously.

"Shark! Say goodbye to your proud monster!"

"Do you really think so?"

At that moment, the shark's calm and collected question startled IV, who then saw that the puppet threads that had been wrapped around the [Aviation Shark] had all snapped off.

This made IV's face darken, and he questioned the shark:

"Damn it! What did you do?!"

"Hmph, I didn't do anything. This is just the effect of the [Left-Handed Shark] as an overload material for the [Aviation Shark].

With a slight sneer, the shark immediately revealed why the [Giant Slayer] could not destroy the [Air Shark].

"Monsters Xyz Summoned using only WATER monsters, including [Left-Handed Shark] on the field, will not be destroyed by monster effects!"

"Damn it! If that's the case..."

Upon learning from the shark that the [Aviation Shark] couldn't be destroyed by its effects alone, IV's face immediately darkened. In that case, the [Giant Slayer], with its low attack power, was of no value to him.

So, IV immediately revealed another card in his hand:

"Well then, how about this! I activate the effect of [Machine Golem - Nightmare] (original) in my hand! This card can be Special Summoned from your hand by Tributing 1 Xyz Monster you control!"

What I want to liberate is, of course, the [Giant Slayer]!

As the card fell, the [Giant Slayer] on the field immediately turned into specks of light and dissipated, reforming into a massive creation composed of deep purplish-red, twisted humanoid puppets assembled together.

The twisted monster caused even the children, including Kotori, Yuma, and Tetsuo, who were just watching, to feel a sense of physical discomfort.

However, IV himself didn't pay much attention to the monster's appearance, instead continuing to explain the effect of his [Nightmare] on the field:

"And the [Nightmare] summoned by this effect can be used as two Xyz Materials when Xyz Summoning!"

So now, I'm using the Level 8 [Machine Golem - Nightmare] on the field to create a stacking network of monsters! Xyz Summon!

Show yourself! [No. 40 Mechanical Puppet - Heavenly String Player] (Original)!

As the monster [Nightmare] split into two orbs of light and disappeared into the Xyz Summoning channel, Yuma, who had seen it before, saw the Dark Puppet with the appearance of a fallen angel, immediately wielding a greatsword and landing on the field of IV.

As the [Heavenly String Player] arrived, IV immediately grinned and said:

"Since it can't be destroyed by effects, then let's destroy it with combat, right?! Go, [Heavenly String Player], attack [Air Shark]!"

As mentioned in IV, the [Aviation Shark] that was slashed down by [Heavenly Strings] immediately turned into an explosion of fire, and this fire caused the shark's LP to drop from a full 4000 points to 2900 points.

Seeing that he had indeed caused harm to the shark, IV breathed a slight sigh of relief.

"Very good. The shark is not an invincible opponent now. Moreover, the effect of his magic card [Rock Salvage] will be nullified next turn."

This area, named "[Lava Ocean]," is enough to keep sharks at bay!

With this in mind, IV ended the round.

"That's it for me, round over! Now comes the scorching hell!"

As IV stated, the moment he ended his turn, the cold wind and ice vanished instantly, replaced by a renewed eruption of the volcano and the flow of lava. Even Yuma was scalded by the surging hot wind.

"It's so hot! So hot! So hot!"

Meanwhile, in the arena, seeing the lava flow again, the shark remained unfazed and continued with its actions:

"My turn, draw a card!"

After seeing the true nature of the card he had drawn, the shark immediately slapped it onto his D panel.

"I summon [Slicing Shark] from my hand!"

As the shark slammed down the card, a fish-like monster, seemingly covered entirely in armor, with a black head and a body and fins made of red and white stripes, appeared on the shark's field, accompanied by a current of water.

The square fins of this cutting shark also have a circular chainsaw blade attached to each of them, which may be the origin of its name, "Cut Shark".

Upon seeing the shark summon a water-attribute monster as usual, IV immediately burst into laughter:

"Fool! The Field Spell Card [Lava Ocean] destroys WATER monsters when they are summoned! Your monster won't survive here, shark!"

Immediately, everyone saw a giant lava serpent, seemingly wreathed in flames, leap out of the magma and lunge to tear at the [Cut-off Shark] in the shark arena, however…

The next second, as the shark's mouth curled slightly, a protective shield flowing with colorful light appeared beside the [Cut Shark], protecting it within it.

The giant lava serpent, upon colliding with the protective shield, transformed into specks of light and vanished.

"This is……"

Just as everyone was wondering, a few sharp-eyed people noticed that one of the two cards that the shark had covered up had already been opened.

The shark didn't keep them in suspense and went straight to explaining the effect of the trap card it had activated:

"Continuous Trap [Adaptive to Adversity]: As long as this card is face-up on the field, WATER monsters you Normal or Special Summon cannot be destroyed by the effects of Spell/Trap Cards!"

As he spoke, the shark looked at IV with a mocking gaze.

"IV, did you think I wouldn't make any preparations to face you? Now, with the effects of [Adversity Adaptation], [Lava Ocean] is completely useless!"

This announcement immediately darkened IV's expression, and at that moment, the shark activated the [Slice Shark] effect:

"Then, I activate the effect of [Cut Shark] on my field! This effect can be used once per turn: Target 1 WATER monster you control, and Special Summon 1 Fish-Type monster with the same Level but a different Name from that monster from your Deck in Defense Position!"

As he spoke, the shark pointed to the [Cut-Shark] on his field and said...

"Now, I choose to Special Summon a Level 4 Fish-Type monster from my Deck, the same level as [Cut Shark]! And the monster I choose to summon is [Right-Handed Shark]!"

As the water surged in the shark tank, a bighead shark that looked exactly like a mirror image of the [left-handed shark] appeared, except that its original body color had changed from a brighter blue to a deeper grayish-purple.

And after [Right-Handed Shark] appeared, the shark immediately said:

"Then, I activate the effect of [Left-Handed Shark] in my Graveyard! If this card is in my hand or Graveyard and I control [Right-Handed Shark], Special Summon this card."

The water swirled, and the [Left-Handed Shark] reappeared, but its level seemed to have changed this time.

"The [Left-Handed Shark] that was Special Summoned from the Graveyard will become a Level 4!"

At this moment, Shark had gathered three Level 4 monsters on the field, and IV's face immediately darkened, because he already had a premonition of which monster Shark would summon.

As if responding to the premonition of IV, the shark began to chant:

"Now, I'm stacking my Level 4 [Cut Shark], [Right-Handed Shark], and [Left-Handed Shark] on my field! I'm building a stacking network of three monsters! Xyz Summon!"

Appear! [No. 32 Sea Bite Dragon Shark Dragon] (Original)!

Chapter 446 Overwhelming the Shark with a Huge Advantage, IV. The Dawn of Victory

"Hmph, it really is that monster!"

Looking at the deep-sea dragon with its brown carapace, whose scales reflected a faint red glow against the backdrop of the surrounding lava environment, IV immediately let out a mocking sound.

Upon hearing IV's words, the shark frowned and immediately questioned IV:

"IV, what do you mean by that?"
