Chapter 916: Triangular Acceleration!

“The ultimate form of synchronization?”

You Xuan smiled slightly, also feeling a growing anticipation.

It’s finally coming.

The legendary supreme Mirror Water Heart, ultimate synchronization, triangular acceleration synchronization—originally pioneered by Yusei Fudo in pre-Zone history, it was later taught to Yusei by Antinomy after the timeline shifted, enabling Yusei to awaken “Ultra-Limit Acceleration Synchronization” during their final duel.

In truth, You Xuan had long wondered whether acceleration synchronization absolutely required a D-Rider.

In the 5D’s anime duels, key scenes were almost always conducted via riding duels, and no one had ever used acceleration synchronization in traditional standing duels without a D-Rider.

Moreover, in the anime’s depiction, during acceleration synchronization, the duelist and D-Rider become one, riding at faster-than-light speed, vanishing in a flash of acceleration, then reappearing with the synchronization summon already complete. If this portrayal holds, then theoretically, acceleration synchronization might indeed be possible only while riding a D-Rider.

But if that’s the case, then duelists from the Synchronization Dimension would be at a severe disadvantage when dueling traditional standing duelists from other dimensions. No bike, no Wangpai summon—what if they faced an invasion from a dimension where opponents don’t ride? They’d be doomed.

So for a long time, You Xuan had been pondering: could acceleration synchronization be achieved by running?

Logically, the D-Rider is merely an acceleration tool; the key to synchronization summoning lies in the perpetual motion engine inside the D-Rider releasing Yusei Particles. Then, if a miniature perpetual motion engine were installed into the Duel Disk, could a duelist achieve acceleration synchronization by surpassing light speed on foot, without a D-Rider?

But then again, that would make the duelist sound like the Flash.

You Xuan chuckled briefly.

Forget it for now. Regardless, this was his first time observing “triangular acceleration synchronization” up close in actual combat—better to observe carefully and record data; he might develop further applications later.

Antinomy: “Special summon ‘Tech-Type Drillfish’ from your hand!”

【Tech-Type Drillfish, ATK 100】

“Tech-Type Drillfish can be special summoned from the hand when only ‘Tech-Type’ monsters are on your field.”

Antinomy said.

“Level 1, Tuner monster ‘Tech-Type Gear Zombie’!”

“Level 1, ‘Tech-Type Drillfish’!”

“Tuning!”

【1+1=2】

“Release limiter: 2 stars! Open regulator! Navigation system—all clear!”

Antinomy raised his arm high.

“Go! Synchro Summon! Eon—”

“—Tech-Type Swap Dragonfly!!!”

【Tech-Type Swap Dragonfly, ATK 300】

You Xuan: “Two normal Synchro monsters, one Synchro Tuner. Preparation is complete. I’m truly looking forward to this.”

Antinomy: “Supreme Mirror Water Heart!”

Though called Mirror Water Heart, his Tri-Eagle was coated in crimson radiance, as if burning. The D-Rider accelerated to full speed, resembling a fiery sphere about to pierce the sky.

“Release limiter: maximum stars! Open regulator—all clear! Infinite power, break through time and space, open the unknown world!”

The roar of the Tri-Eagle reached its peak; Antinomy himself seemed to be engulfed in flames.

“Go! Triangular Acceleration! Eon—”

“—Tech-Type Spear Cannoner!!!”

The Tri-Eagle, as it accelerated, vanished like a beam of light from the track; the galactic data stream exploded into a silver-blue vortex at the geometric center. The three Tech-Type monsters, during tuning, became blazing meteors, their spinning orbits sparking energy flashes. In an instant, countless thrusters roared from the torn dimensional rift. A crimson-painted mechanical god descended from the sky, its impact wave forming a spiraling vortex.

Angular, streamlined armor covered in energy-conducting patterns, ocular lenses flashing quantum-blue light, metallic crowns constantly sparking arcs of electricity. Multi-layer composite armor displayed red-and-black technological patterns; elbow joints occasionally erupted with jet propulsion flames. The massive spear-cannon in its hands was forged from alloy, its muzzle extending countless photon energy blades to form a cutting edge, leaving spiraling afterglows in the air with each swing.

Triangular Acceleration Synchro Summon: Tech-Type Spear Cannoner!

【Tech-Type Spear Cannoner, ATK 4000】

“Mr. You Xuan, this is my full power—Tech-Type Spear Cannoner!”

Antinomy declared.

“Next, this card!

Speed Spell—Final Attack!”

A Speed Spell appeared behind him, its silver-white energy storm fully amplifying the Spear Cannoner.

“Final Attack can only be activated when your Speed Counter is eight or higher!” Antinomy said. “Until the end of this turn, double the ATK of one monster on your field!

Double the ATK of ‘Tech-Type Spear Cannoner’!”

【Tech-Type Spear Cannoner, ATK 4000 → ATK 8000】

You Xuan: “Eight thousand ATK? That’s terrifying.”

The Divine Flame Emperor Uria weakly let out a whimper, as if agreeing with its master.

Eight thousand? That’s insane—who could possibly beat this?

At this moment, You Xuan confirmed his deduction. Indeed, the opponent’s previous turn was precisely to preserve an extra Speed Counter by using “D.D. Crow.” Had the Spirit Wall not removed a thousand ATK from Uria, Antinomy’s Speed Counter would have dropped to six after last turn’s attack, rising only to seven this turn.

Speed Spell—Final Attack requires at least eight Speed Counters to activate; without last turn’s setup, this turn’s counterattack wouldn’t have been possible.

“Go! My full power!”

Antinomy roared.

“Tech-Type Spear Cannoner, attack ‘Divine Flame Emperor Uria’!”

The Spear Cannoner’s arm device erupted with overcharged white steam; energy conduits blazed brilliantly; the photon blades shattered the critical threshold, slicing the air into quantum fissures.

Spiral light tore through space, cleaving through Uria’s fiery breath. The photon heavy blade mercilessly ripped open the illusion demon’s body; the crimson dragon burned as it fell.

Of course, the full three-thousand-point damage was entirely negated by the “Soul Wall,” never reaching You Xuan’s D-Rider.

“End Phase: Spear Cannoner’s ATK returns to normal.” Antinomy said.

【Tech-Type Spear Cannoner, ATK 8000 → ATK 4000】

“Turn ends.”

Antinomy exhaled deeply again.

Success. He had defeated the legendary illusion demon.

Moreover, the Spear Cannoner’s summon had given him immense confidence—he now felt certain he held victory even against a king-level opponent like You Xuan.

The anime Spear Cannoner possessed overwhelming dominance absent from the real card; it wasn’t an exaggeration to say its appearance alone could decide half the duel.

The anime Spear Cannoner’s effect could negate and destroy any monster summon, flip summon, special summon—even those triggered by card effects.

Furthermore, the real card could use its summon-negation effect only once per turn; the anime version had no such limit. Its limit was instead the number of Synchro Materials used in its own Triangular Acceleration Synchro Summon.

Meaning, since Antinomy had just used three monsters for Triangular Acceleration Synchro, Tech-Type Spear Cannoner could negate up to three monster summons by the opponent.

My Spear Cannoner stands on the field and can negate three summons—how could you possibly turn this around?

“My turn, draw.”

You Xuan said calmly.

“Activate Spell Card ‘Monster Recovery.’

Shuffle all cards in my hand and field back into the deck, then draw five cards.” (Original card)

All of You Xuan’s cards turned to golden light and returned to his deck, automatically shuffling with a rustling sound. Then, five cards from the top of the deck popped up automatically.

“Tech-Type Spear Cannoner, the power of Triangular Acceleration Synchro—is truly astonishing. But…”

He smiled mysteriously.

“You don’t seem to fully grasp the strength of the illusion demon.”

“What?” Antinomy gasped.

Does the illusion demon have abilities I don’t know about?

“The final effect of Divine Flame Emperor Uria,” You Xuan said. “When this card is in the graveyard, you can send one trap card from your hand to the graveyard to special summon this card from the graveyard.”

Antinomy frowned: “So that’s it—it can actively revive itself…”

Indeed, this ability raised Uria’s danger level another notch—no wonder it was a legendary monster widely known in the Duel Monster world.

But—

As You Xuan discarded a card to the graveyard, magma erupted from the ground; Uria showed clear signs of reviving.

Antinomy roared: “At this moment! Activate ‘Tech-Type Spear Cannoner’s’ effect!

Negate and destroy any monster summon, special summon, or flip summon!

I negate Uria’s revival!”

Spear Cannoner swung its great spear; Badao energy spread across the field, instantly slamming shut Uria’s coffin lid, freezing it in place.

“So strong—so incredibly strong. Even the illusion demon’s summon can be negated.”

You Xuan said.

“Then I activate Uria’s effect again: discard one card from hand to revive ‘Divine Flame Emperor Uria’ from the graveyard.”

Antinomy: “!!!”

Only now did he suddenly realize the severity of the situation.

Uria’s effect—discard one card to revive—has no once-per-turn limit!

Yes, his Spear Cannoner has no activation limit per turn, and neither does Uria.

Anime fake card versus anime fake card—both effects are fake, so it’s a contest of who’s more fake.

Spear Cannoner’s activation limit is based on the number of Synchro Materials used—maximum three times. Uria’s limit depends on the number of trap cards in the controller’s hand.

And judging by this calm, composed reaction of his opponent, the number of trap cards in his hand must be…

Of course—this opponent began the duel by setting three traps, clearly building a deck specialized around Divine Flame Emperor Uria as a trap-focused strategy.

Even ignoring this opponent’s king-level fate power, the deck itself is heavily trap-oriented, making it highly probable he drew many traps.

But Antinomy had no other choice—he gritted his teeth: “Activate ‘Tech-Type Spear Cannoner’s’ effect again! Negate Uria’s revival!”

Yes, he had no alternative.

To resurrect the Divine Flame Emperor Uliya, You Xuan had already discarded two trap cards into the graveyard. The Divine Flame Emperor Uliya’s attack power is determined by the number of trap cards in the graveyard—meaning if revived now, Uliya’s attack would immediately reach 7000 points.

The Attack Power of the Spear Cannoner had already dropped back to 4000; this shot alone would seal his defeat.

You Xuan: “Activate the effect of the Divine Flame Emperor Uliya: discard a trap card from your hand to revive the Divine Flame Emperor.”

Antinomy sighed helplessly: “Third time using the effect of ‘Tech-Type Spear Cannoner’ to negate the summon of the Divine Flame Emperor Uliya.”

But this negation is the final one. Now, the Spear Cannoner’s maximum three summon negations have all been exhausted.

And as expected, You Xuan revealed another card from his hand.

“Discard another trap card from your hand and activate the effect of ‘Divine Flame Emperor Uliya.’”

The Divine Flame Emperor Uliya is revived.

Antinomy: “...”

He had no moves left.

The Spear Cannoner’s full power was already his maximum—his absolute limit. He had used everything, yet it still wasn’t enough. He was utterly out of options.

Three consecutive summon negations, but this relentless suppression had merely been preparation—for an even more violent explosion, one a hundred times fiercer than before.

The immortal crimson dragon burst once more from the molten lava, rearing its head and unleashing a defiant roar!

【Divine Flame Emperor Uliya, Attack 9000】

Attack 9000!

“Battle,” You Xuan said. “Divine Flame Emperor Uliya, attack ‘Tech-Type Spear Cannoner.’”

A dimension-shattering sound, sharp enough to rupture eardrums—Uliya’s dragon mouth churned with magma; the crimson fire column turned blinding white the instant it left his jaws, scorching spiral vacuums into the space along its path.

The Spear Cannoner’s armor instantly glowed blinding crimson; its layered energy shields shattered at the molecular level the moment they met the flame column. The mechanical titan’s body began peeling away layer by layer under absolute energy suppression—its thrusters melted into molten iron, the white-hot flames pierced its energy core, and millions of photonic components scattered like dandelion seeds in a gale, dissolving into glittering data stardust in the explosion.

【Antinomy, LP 1500 → LP 0】
