When Kagawa Hideyuki saw the card You Hong held between his fingertips, a chilling cold instantly shot up to his head!

You Hong was already so strong without using cards; how strong would he be with them?

He didn't know.

Therefore, he absolutely couldn't let him use it again!

"Stop!"

A hoarse roar erupted from Kagawa Hideyuki inside the Alternative-Zero armor, and his body burst forth with tremendous speed, slamming into You Hong.

"Quite a quick reaction," You Hong chuckled, about to dodge.

"Accele Vent!"

A cold electronic voice interrupted him.

A card with black-gray energy patterns flowing along its edges was swiftly swiped through the Summoner!

Buzz—!

The ear-piercing sonic boom instantly tore through the Mirror World's silence!

Alternative-Zero's figure suddenly blurred, stretched, and transformed into a black-gray lightning bolt so fast it seemed to rip the retina.

One moment he was several meters away; the next, an iron fist covered in spiked armor had torn through the air, carrying terrifying kinetic energy capable of shattering steel plates, and was smashing directly towards You Hong's defenseless face!

The speed was so great it almost surpassed the flow of time!

"Fall down!"

Kagawa's roar distorted in the high-speed, carrying the resolve of a fatal blow!

Just as that iron fist was one millimeter away from the platinum faceplate—

"Skill Vent - Trick Room!"

The same electronic sound rang out.

On his left wrist, the card with a pink-purple base and swirling, kaleidoscopic space patterns had silently slipped into the Summoner's card slot.

Ding!

A crisp, light sound, like crystal colliding.

Centered on You Hong, a visible, hemispherical pink-purple force field instantly expanded, silently enveloping an area of several tens of meters!

Something bizarre happened!

The extremely fast silver-gray lightning bolt that was Alternative-Zero, upon rushing into the force field, was like falling into the thickest syrup!

His supersonic speed, capable of tearing the sound barrier, was infinitely slowed and frozen at this moment.

From the outside, Kagawa Hideyuki seemed to have been put on slow motion, turning into a clumsy, difficult-to-move tin puppet.

At the same time, You Hong, who had originally been 'leisurely' making a casual sidestep, suddenly had his speed soar within the force field.

The platinum figure instantly blurred and disappeared from Kagawa's vision.

The next moment, a fist encased in silver-white armor, carrying an irresistible power, rapidly magnified in Alternative-Zero's vision!

"Bang!!!"

A solid uppercut landed squarely on Alternative-Zero's chin!

The heavy armored head sharply snapped backward, causing the entire massive body to lift off the ground and fly backward!

Rumble!!!

Alternative-Zero, like a broken sack hit by a giant hammer, violently crashed through the roof of a discarded bus by the roadside, his entire upper body embedded within it, the sound of twisting metal ear-piercingly loud.

"Uh ah—!" Kagawa Hideyuki let out a painful groan, the new cracks on his chest armor striking.

"Tsk, I already knew you had this card."

You Hong stood at the center of the pink-purple force field, shaking his punching fist. As a Transmigrator, how could he not know Alternative-Zero's specific configuration?

"Bastard... Bastard—!!!"

Kagawa Hideyuki's completely insane roar erupted from the bus wreckage.

It was a humiliation and despair of all his trump cards being seen through, all his efforts crushed.

Alternative-Zero violently pulled his body from the wreckage, the armor groaning under the strain.

He no longer charged, but instead used all his strength to insert a card and summon.

"Advent!"

"Hissga—!!!"

Accompanied by a grating, sharp hiss, a cricket monster the size of an ordinary human appeared before You Hong.

This monster was Alternative-Zero's Contract Beast—the Mad Cricket Thug!

"Get him!" Kagawa Hideyuki pointed at You Hong, his voice distorted by extreme rage.

The Mad Cricket Thug let out a sharp shriek, its massive body, with an Aura of crushing everything, lunged at You Hong.

At the same time, Kagawa Hideyuki desperately inserted another card with a peculiar pattern into the Summoner!

"Final Vent!"

"Tsk, you never learn, Professor." You Hong pouted, his tone relaxed. "Alright, let's see whose Contract Beast is tougher."

He flipped his wrist, and the card, already prepared, with a deep blue background depicting Blastoise's cannons fully open, spewing a blue light beam that pierced the heavens, instantly slid into the Summoner!

"Final Vent! Hydro Cannon!"

Buzz—Boom!!!!

Blastoise descended from the sky, its giant cannons already raised, the water-type energy compressed to the extreme within the muzzles erupting in a sky-piercing azure light.

The moment the Final Vent command was given, a thick, condensed, liquid sapphire-like beam of destructive light, carrying the terrifying power to tear space, roared forth.

Its target was the charging Mad Cricket Thug, and Alternative-Zero, who had just assumed his finishing pose behind it!

The Mad Cricket Thug's faint finishing move glow had just ignited when it was completely engulfed by this heaven-piercing blue torrent!

There was no explosion.

Only absolute power.

Wherever the Hydro Pump passed, the Mad Cricket Thug was violently pushed backward.

The rampant Hydro Pump, its momentum undiminished, slammed into Alternative-Zero, who had just used Splash and was preparing to launch a finishing kick!

"Uh—Pfft!"

Kagawa Hideyuki only managed to let out a short, miserable cry.

The black-gray chest armor completely shattered, and then his entire body, like a kite with a broken string, was swept away by the violent current, violently smashing into the huge full-length mirror behind him.

Bang—Crash!!!

The mirror shattered with a resounding crack!

Alternative-Zero's figure, like a cannonball propelled at high speed, accompanied by flying glass shards, violently crashed back onto the cold floor of the 401 laboratory in the real world.

The heavy armor scraped a trail of sparks on the smooth floor, tumbling several times before stopping. The transformation's white light instantly dissipated, revealing Kagawa Hideyuki underneath, his face as pale as gold leaf.

"Professor!"

"Kagawa-sensei!"

Tojo Satoru and Nakamura So, who had been guarding the mirror, rushed over, their eyes bloodshot.

Just then, the broken full-length mirror rippled, and You Hong's figure, as if passing through a curtain of water, easily walked out.

The platinum armor shone brightly under the laboratory's stark white lights, a stark contrast to Kagawa Hideyuki on the floor and the two panicked individuals.

He deactivated his transformation, reverting to the young man in a casual jacket, casually brushing off non-existent dust from his shoulders. Looking at the three disheveled figures on the floor, his tone was calm:

"Now, you know, don't you?" You Hong's gaze swept over Tojo Satoru and Nakamura So, finally landing on Kagawa Hideyuki. "With your meager strength, I only need to get a little serious, and you can't handle it. How do you expect to challenge Shiro Kanzaki?"

Kagawa Hideyuki struggled to look up, his eyes fixed on You Hong: "Even... even a guy like you isn't his opponent?!"

You Hong glanced at him, saying nothing, but a faint 'tsk' echoed in his mind.

If that guy didn't have that 'Time Advent' cheat ability...

Tsk, but once I make the Dialga card...

He watched You Hong's silence, taking it as an affirmation.

That despair, heavy as a mountain, completely crushed his last shred of hope.

"I... we'll join." Kagawa Hideyuki's weak voice suddenly sounded, his eyes showing a trace of resigned defeat. "Join your police force's 'Special Department'."

Tojo Satoru and Nakamura So both stared at him in astonishment.

Kagawa Hideyuki struggled, and with Tojo Satoru's help, managed to sit up. He took a few gasps, his gaze locked on You Hong: "But... I have a condition."

He paused, his voice carrying a desperate ruthlessness, "I know that within your police System, there are some dirty worms, sucking blood like maggots! Get rid of them... all of them! Not a single one left!"

He stared into You Hong's eyes, enunciating each word: "As long as you do that, we... will serve you! Our technology, our strength, we can give it all to you."

The laboratory was completely silent.

Only the faint hum of instruments.

You Hong looked at the mad glint in Kagawa Hideyuki's eyes, and a clear arc suddenly formed at the corner of his mouth.

"Deal."
