Ben10: A Romantic Adventure with a Gender-Swapped Class

Her fingers hovered in mid-air as she dialed, then she suddenly looked up, her gaze returning to Kevin. A mischievous smile, tinged with "I knew this would happen," played on her lips as she slowly uttered a sentence.

"I just wanted to ask..." she deliberately dragged out her words, a hint of anticipation in her eyes, "You'll regret it later, won't you?"

Kevin spoke almost without hesitation, his metal-covered head nodding instinctively, and a resolute, defiant metallic voice rang out, echoing across the empty highway.

"I already regret it."

The voice was fast and loud, carrying a kind of "self-abandonment" honesty, as if these words had been held back in his metal chest eight hundred times, just waiting to burst out at this moment.

Soon, everyone gathered on Kevin's spaceship.

Kevin's spaceship hovered silently in the cold night outside the castle, the atmosphere inside somewhat stagnant.

Mo Bai and Xiao Ban practically dragged themselves over, their faces clearly showing the distress of being "forced to work overtime."

Xiaowen said to meet here, so they had no choice but to come.

As soon as they entered, two pairs of eyes, like searchlights, instantly locked onto Aji, who was huddled in the corner.

That look wasn't exactly fierce, but it was definitely not friendly either.

The mixture of helplessness at "It's you who caused trouble again" and disgust at "I really want to throw you out" felt like invisible needles, making Aji feel uncomfortable all over.

He subconsciously shrank deeper into his seat, trying to avoid those two extremely piercing gazes, and felt a chill on the back of his neck.

Xiaowen ignored the subtle atmosphere, her fingers flying across the Tian Gonghui terminal she carried, the pale blue light illuminating her focused profile. After a moment, she looked up, her voice tinged with seriousness.

“We found it. There are over 900 legally registered extraterrestrial records on Earth, but now we can only pinpoint their exact locations…” She paused, then announced a chilling number, “Only about 300 left. This number… something’s not right.”

“This doesn’t sound like the work of the Eternal Warriors either,” Xiaowen added, her brow furrowed.

Xiao Ban, who had been "torturing" Aji with his eyes, finally shifted his attention slightly and nodded.

“That’s right.” Her gaze quickly returned to Aji, her bright eyes clearly saying, “Confess and you’ll be treated leniently, resist and you’ll be punished severely.” “Then how do you plan to explain this?”

Aji's throat felt like it was blocked by something. He made several "uh...uh..." sounds, his face turning a little red. Finally, he simply shut his mouth tightly and stared blankly at the ceiling.

“Then let’s go find someone who knows the truth and ask them.” Mo Bai stood up, breaking the deadlock. Her voice was a little tired, but also decisive.

Soon, the space shuttle's engines roared, carrying everyone to a landing in front of an abandoned castle belonging to the Eternal Warriors.

The pale moonlight cast a deathly silver frost over the eerie stone building.

The castle gates were wide open, revealing a pitch-black interior, like the gaping mouth of a giant beast.

The crowd filed in, their footsteps echoing in the empty hall.

The beam of the flashlight swept across the dusty stone pillars, the cobweb-covered high windows, and several cold, dusty suits of knight's armor in the corner.

At the far end of the hall, a huge, menacing stone dragon sculpture coiled, casting a massive shadow in the darkness.

They searched every corner, but they couldn't find a single living person, or even a ghost.

Little Ben didn't believe it, so she slapped her wristwatch. A green light flashed, and the super monster took her place.

She lowered her body, her nostrils flaring rapidly, carefully sniffing every trace of scent on the cold stone bricks.

After a while, she transformed back into human form, dusted off her hands, and spoke with a slightly bored but certain tone.

"No response, they've left."

"Then let's go home and sleep?" Mo Bai yawned at the right moment, with a few tears welling up in the corners of her eyes. Her suggestion was exactly what people wanted to hear.

"I agree!" Xiao Ban's lips immediately curled into a relieved smile, and his voice became cheerful.

However, that relaxed atmosphere lasted for less than a second.

"Bang—!" A heavy thud, accompanied by Aji's cry of pain, sounded as if he had tripped over something and fell heavily onto the cold floor.

Immediately afterwards—"BOOM!!!" An even louder tremor, like a heavy object hitting the ground, came from the end of the hall!

Everyone looked up abruptly, their hearts leaping into their throats.

The once lifeless stone dragon sculpture suddenly had two eerie, flickering red lights shining from its eye sockets!

Its massive, stone-made neck creaked and slowly, stiffly, twisted, its cold, unfeeling gaze locking onto the uninvited guest in the center of the hall.

The massive stone maw opened slightly, and a faint, scorching heat emanated from it.

"Looks like I won't be able to sleep tonight..." Mo Bai's complaint was filled with helplessness, before she could finish speaking.

A blazing, violent pillar of orange-red fire, like lava erupting from hell, suddenly spewed from the stone dragon's gaping maw! The scorching heat instantly swept through the hall, distorting the very air!

At the critical moment, Xiaowen pushed her arms forward with all her might, and a huge celestial energy shield with a flowing purple halo instantly opened up, barely blocking the surging torrent of flames.

Flames licked at the shield, emitting a terrifying hissing sound.

"I don't remember it breathing fire!" Xiaowen gritted her teeth to maintain the shield, her voice sounding strained amidst the roar of flames.

The mechanical dragon seemed to be enraged. Its huge claws, covered with an unknown alloy, were raised high and slammed into the purple shield with a shriek that tore through the air!

"Crack!" Clear cracks spread out instantly like a spider web.

Immediately afterwards, the dragon raised both of its front claws above its head, clenching them into huge metal fists. With a world-destroying aura, it slammed them down on the already cracked protective shield like two heavy hammers!

The sturdy celestial energy shield shattered like fragile glass! Purple energy fragments scattered everywhere!

"Polaris!" The little boy reacted the fastest, and with a shout, he transformed into Polaris.

"Watch this!" Kevin roared, rushing to a dusty knight's armor and slamming his hand onto the cold breastplate.

The metal flowed as if alive, quickly covering his arms and torso, instantly transforming him into a gleaming metal warrior.

The metal-covered hands writhed and transformed into two enormous meteor hammers covered in ferocious spikes!

Kevin, wielding his meteor hammer, was the first to charge.

Mo Bai was even more decisive, transforming directly into the ultimate little bob.

"Alright, mechanical lizard, let's see how tough you are!"

Kevin, who was in the lead, was swinging his spiked meteor hammer and was about to smash the mechanical dragon's leg joint!

Just then, Xiao Ban moved as well. She suddenly raised her huge magnetic clamp arms, and an invisible, powerful magnetic field instantly spread out.

The scattered metal objects in the hall—broken candlesticks, fragments of armor, even metal ornaments on the walls—were as if seized by an invisible giant hand, whistling through the air as they frantically swarmed toward the massive body of the mechanical dragon.

"Crackling and crashing!" Metal parts rained down on the mechanical dragon, creating a dense series of impact sounds.

However---

"Hey! You surnamed Tian!" Kevin's terrified cry suddenly rang out!

Kevin, who was halfway through his charge, found his gleaming metallic armor drawn to the powerful magnetic pull of Polaris.

He was like a nail drawn to a magnet, his direction suddenly changed, and he cried out as he was violently pulled onto the cold metal belly of the mechanical dragon, nearly hitting himself with the meteor hammer in his hand.

The little boy froze, and quickly removed the magnetic field.

Kevin tumbled back to the ground in a sorry state, his metal armor clanging against the stone slabs with a crisp sound.

No sooner had one problem been solved than another arose. Just as Kevin was getting up, grimacing, Mo Bai's loud voice echoed throughout the hall.

Cover your ears!

Before he finished speaking, six smooth-edged, high-speed spinning blue energy discs shot out from the body of Ultimate Little Bobo like a swarm of bees leaving their hive.

They precisely circled the mechanical dragon's massive body, instantly forming an encirclement.

The next second, six terrifying sonic beams, visible to the naked eye and distorting the air, erupted simultaneously.

Like six invisible, high-frequency vibrating giant hammers, they slammed down on the mechanical dragon in the center from all directions.

The sound waves overlapped and resonated wildly within the sealed hall of the ancient castle.

Xiao Ban, Xiao Wen, Kevin, and even Aji, who had just gotten up, all covered their ears tightly.

The sound seemed to penetrate the brain, making one's internal organs churn!

The mechanical dragon was the first to bear the brunt. Its hard alloy shell groaned under the ultra-high frequency resonance, thick smoke billowed from its joints, and its internal parts emitted ear-piercing cracking sounds.

At the same moment, all the surviving glass windows in the hall—regardless of size—shattered completely with a loud "bang"! Glistening shards rained down like hailstones!

Boom——! ! !

With a deafening roar as the metal structure completely collapsed and a violent explosion, the once invincible mechanical dragon was reduced to a pile of twisted, smoking scrap metal, which collapsed to the ground and fell completely still.

The entire castle hall was in a mess, with cracked walls that seemed about to collapse completely at any moment.

Mo Bai clapped his hands in satisfaction, a flash of red light appeared, and he transformed back into an Earthling.

He glanced down at a twisted piece of machinery at his feet, a slightly roguish smile playing on his lips. He then stepped on it and crushed it to pieces with a "crack".

“Done,” he said casually.

However, the expected cheers or praise did not come. Mo Bai looked up in confusion and realized that something was wrong.

The little boy had already returned to his original form and was now standing in front of him with Xiaowen and Kevin.

Three people, six pairs of eyes, all fell on him.

Xiaowen crossed her arms over her chest, her brows furrowed slightly, her eyes conveying a speechless expression that seemed to say, "You almost deafened us just now."

"Uh..." Mo Bai's smug expression froze instantly, and she awkwardly scratched her cheek. "Sorry..."

Clang... Clang...

An untimely sound of metal scraping and colliding rang out from behind the group.

Everyone immediately turned around warily, only to see that Aji had picked up a relatively complete set of knight's armor from the ground and was hurriedly putting it on.

The heavy armor clearly didn't fit him properly, and he swayed and clanged as he walked.

He was also comically holding a rusty longsword in his hand, the tip of which was trembling.

Through the gap in his helmet visor, his voice trembled with the shock of surviving a near-death experience and was filled with urgency.

"May I leave now?"

Back inside the relatively safe spaceship, the atmosphere remained somber.

After searching three abandoned castles of the Eternal Warriors, all they found was smashed a bunch of machines and nearly being deafened by the explosions.

Continuing to search blindly like this seems pointless.

Xiaowen leaned back in her seat, her fingers tapping unconsciously on the armrest, her gaze fixed on the deep starry sky outside the porthole, when she suddenly spoke.

“Perhaps we should look at it from a different angle,” she said thoughtfully. “If you want to drive aliens off Earth, where can you find a whole bunch of aliens at the same time?”

As soon as she finished speaking, Xiaowen and Xiaoban's eyes lit up almost simultaneously!

A familiar yet somewhat vague place instantly surfaced in their minds—a place they had visited once with Grandpa Tian Mark when they were twelve years old.

The engines started up again, and the space shuttle cut through the night sky, heading towards some inconspicuous corner of Earth.

Finally, it landed at the end of a quiet street.

Before me was a small supermarket that looked extremely ordinary, even somewhat dilapidated.

Several neon tubes on the sign were broken, causing the words "Open 24 Hours" to flash intermittently.

In the dead of night, all around was deathly silent, except for this shop, which stubbornly kept its lights on, giving off an eerie feeling.

The group pushed open the creaking glass door and went inside.

An indescribable, complex, and intense odor instantly wafted towards me.

It smelled like hundreds of over-fermented fruits mixed with expired syrup, some kind of rusty metal, and bursting swamp bubbles—so intense it almost formed a physical barrier.

"Wow!" Xiao Ban immediately pinched her nose, her brows furrowing into a knot, and complained in a muffled voice, "Has this place always been this smelly and sour? How come I never noticed!" She looked around and saw that the shelves were piled with strangely shaped and strangely colored "ingredients" and "fruits," some of which looked like purple bulbs covered with tumors, and others looked like blue tentacles flowing with slime. Suspicious fluorescent spores were also floating in the air.

They are all products of other planets.

“Because you were only twelve when you came here last time,” Xiaowen said calmly, glancing at Xiaoban with a mischievous smile. “Back then, you smelled terrible.” She deliberately emphasized her words.

Upon hearing this, Mo Bai turned to look at Xiao Wen with some confusion.

"Really? I don't remember smelling it when I was a child?" He tried hard to recall his childhood experiences.

Xiaowen's smile deepened, a hint of smugness in her expression as she explained.

“Because it was all for your benefit,” she said, pointing to the small class. “After you left, she started being unhygienic again.” Her tone was exactly like accusing a slovenly person who never learns from their mistakes.
