Yu-Gi-Oh!: I use an Orichalcos deck

"Hold on!" Yuki gripped the dragon's horn tightly, barely managing to glide it towards the launch base. When the dragon finally crashed onto the base's runway, Yuki was thrown more than ten meters away, covered in injuries.

Staggering to his feet, Yuji discovered that the launch base had been corrupted by shadow energy, and most of the equipment was disabled. Fortunately, an emergency launch pod remained intact, with a green light flashing on the control panel indicating it was ready to launch.

After entering the launch capsule, Yuki initiated the automatic launch procedure. With violent vibrations and roars, the capsule accelerated along the electromagnetic track, finally breaking through the shadow clouds and entering near-Earth orbit.

Looking out the porthole, Yuki witnessed a breathtaking sight—the entire Earth was enveloped in a layer of purplish-black energy membrane, with only a few scattered points of light resisting it. Among these points of light, the International Space Station, like a lighthouse in the darkness, emitted a faint blue glow.

The docking process went exceptionally smoothly, suggesting that the space station's systems had not yet been completely taken over by the Shadow. When the airlock opened, Yuji was surprised to find that the internal gravity was normal, the air was plentiful, but it was deathly silent.

"Is anyone there?" His voice echoed down the corridor.

There was no response. Following the Duel Disk's navigation, Yuki arrived at the central experimental module of the space station. The hatch slid open automatically, revealing a man suspended in zero gravity—he wore a blue and white spacesuit, had short black hair, and his eyes were closed, entangled by countless tiny purple energy threads, like prey in a spider web.

[Target confirmed: Star Dragon Knight Tiangong Xuan]

[Status: Deep Control + Energy Overload]

[Danger Level: Diamond 5]

[Warning: Enhanced Space Environment]

Just as You Ji was about to step forward, the energy threads suddenly contracted, and Tian Gongxuan's eyes snapped open, revealing purplish-black pupils.

The intruder... his voice was distorted like a synthesized electronic voice, awaiting the judgment of the stars!

The gravity system inside the cabin suddenly malfunctioned, and Yuki felt himself floating. Tengu Gen unfolded the Duel Disk, and the surrounding walls transformed into a panoramic projection of the vast universe, with countless stars twinkling in the darkness.

"Duel!" Tiangong Xuan mechanically announced.

"Duel!" Yuki responded, grabbing a handrail to steady himself.

Field Magic: Star Field activated! Genichi Tengu waves his hand, and in this environment, all monsters are treated as Cosmic Attribute monsters and can be Special Summoned regardless of their Summoning conditions!

Countless starlight converged to form the dueling arena, with the two hovering above the Milky Way.

My turn, draw! Tengu Gen's movements were exceptionally elegant in zero gravity. Activate the Spell Card Astral Evolution! Send one Stardust Dragon monster from your Deck to the Graveyard, draw two cards!

Then he activated the effect of Starfield! He continued, "Once per turn, you can Special Summon one Cosmic monster from your hand. I Special Summon Stardust Charge Warrior (ATK 2100)!"

A warrior clad in star armor appeared in the galaxy.

Next, I Normal Summon Stardust Summoner (1500 ATK)! Activate its effect to add one Stardust Spell/Trap Card from my Deck to my hand. I choose Stardust Illusion!

Stack a level 4 Stardust Summoner and a level 4 Stardust Charger! Tengu Gen shouts, "Xyz Summon!" Stardust Photon Dragon (ATK 2500)!

A giant, transparent dragon made of starlight emerged.

Cover two cards, end the turn! Tian Gongxuan sneered, "Before the vast universe, your Saiyans are nothing but dust."

Yuki adjusted his breathing; the zero-gravity environment made the duel exceptionally difficult. He checked his hand: Saiyan Goku, Saiyan Scout, Saiyan Battle Suit, Ki Blast, and Saiyan Fusion Technique.

My turn, draw a card! Lacking a point of leverage, the card-drawing action becomes clumsy. Yuuki draws the Saiyan Spirit Bomb.

Activate the Magic Kasaiyan Spirit Bomb! Destroy all monsters on the field with an attack power of less than 3000!

A massive energy sphere formed in space, but it was blocked by a barrier of starlight when it struck the Stardust Photon Dragon.

Trap Card Stardust Illusion! Gen Tengu flips over a face-down card. If there is a Stardust Monster on the field, you can negate and destroy one Spell Card!

So, Normal Summon Saiyan Scout (ATK 1200)! Yuuki continues, activating his effect: Check one of your face-down cards!

The scout scanned Tengu Gen's face-down card and found it to be Stardust Regeneration—a trap that can revive Stardust Monsters.

Activate the Saiyan Battle Suit equipment magic to increase the Scout's attack power by 500 (Attack Power 1700)!

Battle! Saiyan scouts attack Stardust Photon Dragon!

The scout's energy blast left a bright trail in space, but it was easily dodged by the Photon Dragon, who countered and destroyed the scout. Yuki's health dropped from 8000 to 7200.

"Activate the graveyard effect of Saiyan Scout!" Yuki immediately said, "Add a Saiyan Spell Card from my Deck to my hand! I choose Super Saiyan Transformation!"

Cover two cards, turn ends! Yuuki unleashes Ki Blast and Saiyan Fusion Technique.

My turn, draw! Tengu Gen glanced at his hand and activated the effect of Stardust Photon Dragon! Remove one Xyz Material, Special Summon one Stardust Monster from my Deck! I choose Stardust Assault Trooper (ATK 1800)!

Then he activated the Spell Card Stardust Blaze! He continued, "When there are two or more Stardust Monsters on the field, you can draw three cards!"

Synchro Summon Level 4 Stardust Assault Trooper and Level 4 Stardust Photon Dragon! Tengu Xuan shouted, "Summon Synchro Summon!" Stardust Eternal Dragon (Attack Power 3000)!

An even more majestic Stardust Dragon descended, its scales seemingly inlaid with the entire Milky Way.

Battle! Stardust Eternal Dragon attacks directly! Galactic Breath!

The torrent of starlight struck Youji directly, reducing his health from 7200 to 4200.

Round over! Tian Gongxuan declares that your resistance is futile.

Yuki felt short of breath—not only due to the reduced life points, but also because the space environment itself was draining his stamina. But he noticed that Tengu Gen had no more Xyz Materials on the field, and his hand was almost empty.

My turn, draw a card! Yuki drew a Saiyan who is near death and revived.

Activate the Spell Card Saiyan Resurrection! When your Life Points are lower than your opponent's, you can Special Summon a Saiyan Monster from your Graveyard and double its ATK! Revive, Saiyan Scout (ATK 1200 → 2400)!

Then activate the Magic Card Super Saiyan Transformation! Yuki continued, "When there is a Saiyan monster on the field, its ATK can be doubled again! Saiyan Scout (ATK 2400 → 4800)!"

Battle! Saiyan scouts attack Stardust Eternal Dragon!

The energy blast collided with the starlight, shattering the Eternal Dragon. Tian Gongxuan's health dropped from 8000 to 6200.

Activate Stardust Regeneration! Gen Tengu flips over a face-down card. When a Stardust Monster is destroyed, (Norde) can Special Summon it back to the field!

The Eternal Dragon has reappeared, but its attack power has been reduced to 2500.

Out of Saiyan pride, I draw a card! Yuki drew Instant Transmission.

The round ends!

My turn, draw! Tengu Gen glanced at his hand and activated the effect of Stardust Eternal Dragon! Once per turn, you can destroy one card on your opponent's field! I choose Saiyan Scout!

The star beam hit the scout, but Yuuki immediately flipped over his face-down card: Quick Attack Magic Ki Blast! Reduces Stardust Eternal Dragon's ATK by 1000 (2500→1500) and deals 500 damage!

Tian Gongxuan's health dropped to 5700.

Battle! The Stardust Eternal Dragon is attacking the player!

Even with the reduced attack power, the dragon's breath still took away 1500 health points. Yuji's health points dropped to 2700.

The round ends!

My turn, draw a card! Yuki drew the Saiyan Prince Vegeta.

Activate the Trap Card Saiyan Fusion Technique! Yuuki flips over his last face-down card. When our Life Points take battle damage, we can Fusion Summon a Saiyan Monster from our hand or Graveyard! I fuse the Saiyan Scout on the field with the Saiyan Prince Vegeta in my hand!

A brand new warrior emerges from the fusion vortex—the Saiyan Space Warrior (Attack Power 3500). He wears space armor and is able to adapt to the space environment.

Battle! Saiyan cosmic warriors attack Stardust Eternal Dragon! Cosmic Shockwave!

The energy wave shattered the Eternal Dragon, and Tian Gongxuan's health dropped to 3700.

Round ended!

Chapter 354

My turn, draw a card! Tengu Gen glanced at his hand, then suddenly revealed a strange smile, activating the Spell Card Star Sacrifice! I sacrifice one Stardust Monster on the field to Special Summon one Stardust Synchro Monster from my Extra Deck! I sacrifice Stardust Eternal Dragon to Summon Stardust Blast Dragon (ATK 3000)!

An even more ferocious Stardust Dragon appeared, its entire body shimmering with unstable energy.

Then activate Stardust Blast Dragon's effect! Tengu Gen shouts, "When he is successfully Special Summoned, he can destroy all other cards on the field!" Starburst!

Blast Dragon's entire body emitted a blinding light, instantly vaporizing Yuki's Saiyan cosmic warrior, whose health dropped from 2700 to 0... but then recovered to 1000 the next moment.

Trap Card Instant Teleport! Yuuki flips over the last 913 face-down card. When your Life Points are about to reach zero, you can restore them to 1000 and remove one monster from the field. Special Summon it back to the field next turn!

A desperate struggle! Tian Gongxuan coldly snorted, then covered one card, and the turn ended!

Yuki felt his consciousness beginning to fade. The zero-gravity environment, the drain from continuous duels, the effects of decreasing health... but he couldn't afford to fall here.

My turn... Draw a card! Yuuki used all his strength to draw a card—Super Saiyan Universe Form! A card he had never seen before!

The duel disk suddenly vibrated violently, and a holographic screen popped up:

[Completed adaptation to the cosmic environment]

[Unlock Hidden Form: Super Saiyan Universe Form]

[Effect: Ignores environmental penalties in space, doubles attack power]

"Activate the effect of Instant Teleportation to Special Summon Saiyan Space Warrior!" Yuki announced, then activated the Spell Card Super Saiyan Space Mode! "If there is a Saiyan Space-type monster on the field, its ATK is doubled!" Saiyan Space Warrior (ATK 3500 → 7000)!

The space warrior's armor turned a dazzling gold, surrounded by nebula-like flames.

Battle! Saiyan Space Warriors Attack Stardust Blast Dragon! Supernova Impact!

An energy wave swept across the entire star field like a supernova explosion, and the Explosive Dragon was reduced to ashes in the light. Tian Gongxuan's health dropped from 3700 to 0!

Dark energy was torn apart from him, and the purplish-black threads snapped inch by inch. Tian Gongxuan's body slowly floated in the center of the cabin, and the purple light in his eyes gradually faded.

"How long... have I been controlled?" he asked weakly.

Soon, but the shadows had already taken control of most of the city. Yuki grabbed a handrail to steady himself; "We need your strength."

Tian Gongxuan nodded with difficulty, taking out a card shimmering with starlight from inside his spacesuit: Star Core... the fourth mysterious card... Shadow has collected all three gems... Time is running out.

Yuuki took the card, and the duel disk displayed:

【mission completed】

[Achieve DP1200]

[Unlock Cosmic Form Abilities]

[Obtain the fourth mystery card]

Current DP: 4750

Suddenly, the entire space station shook violently, and alarms blared throughout the cabin:

[WARNING! Shadow energy invasion]

Life support system failure

Oxygen remaining: 15 minutes

We must leave! Tian Gongxuan has activated the emergency escape protocol. Follow me!

The two struggled through the swaying corridor to reach the escape pod. Just as the pod door closed, Yuki saw a mass of purplish-black energy penetrate the space station's outer shell and coalesce into a humanoid shape—the projection of Shadow.
