Phineas and Ferb!

Just as Jiang Li was about to open the portal to the universe, the Omnitrix on his left wrist, which represented the highest authority, suddenly flashed a yellow alert with a peculiar frequency, though it wasn't urgent.

"What's wrong? Another god wants to destroy the universe?" Gwen, holding Jiang Nian, came closer.

"No, it was... a very interesting 'traffic accident'."

Jiang Li brought up the data panel on the watch face, and looking at the fluctuating coordinates, he couldn't help but smile.

"In the two-dimensional animated universe designated Earth-Danville, someone accidentally punched a hole in the dimensional barrier using an extremely crude machine, letting a giant monster from the Null Void of the neighboring <Ben 10> universe slip through."

"An animated universe?" Gwen paused, taken aback.

"Let's go, let's take Niannian to experience the craziest summer vacation in the entire universe. And while we're at it, let's fix that loophole."

Jiang Li pressed the button on the dial, and a portal shimmering with multicolored light opened.

Earth-Danville, Danville, the backyard of Phineas and Ferb's family.

The sun is shining brightly here, and the lawn is a vibrant green.

However, hovering in mid-air was a monster over thirty meters long, covered in red scales and with enormous bat wings—the [Null Void Guardian].

This ferocious beast, which should have been imprisoned in an interdimensional prison, was angrily spewing dark red destructive beams, attempting to burn the entire block to ashes.

Below the monster.

A red-haired boy with a triangular head (Phineas) and a quiet boy with green hair (Ferb), wearing goggles, are frantically banging on a wrench in front of an extremely large and exaggeratedly designed "Giant Capture Mecha".

"Hey, Ferb! The plasma engine of the beast-catching net seems to be underpowered; this big guy's dimensional mass is too heavy!"

Phineas wiped the sweat from his forehead, his tone not showing fear, but rather excitement at the challenge.

Beside them, a little girl wearing a pink bow (Isabella) peeked out. "Hi, Phineas, what are you doing?"

"We're catching a giant lizard from another dimension that accidentally got lost!" Phineas replied enthusiastically.

On the big tree.

A platypus wearing a brown agent hat (Agent P / Perry) is nimbly dodging the monster's fireballs. It grits its teeth and tries to restrain the monster with its agent launcher, but ordinary high-tech weapons are useless against this dimensional beast.

"Roar--!"

The Null Void Guardian opened its blood-red maw, and a terrifying beam of death light was aimed directly at Phineas and Ferb in the backyard!

"Drop!"

At the critical moment, a green data halo lit up in mid-air.

Jiang Li, along with Gwen and Jiang Nian, appeared out of thin air on the lawn in the backyard.

Jiang Li didn't even raise his hand; he merely glanced at the beam of death light.

Buzz!

With the highest administrator privileges activated, the deadly beam that was powerful enough to destroy the entire street vanished without a trace, as if erased by an invisible eraser, ten meters above the ground.

Agent P (Perry) landed on a tree branch, watching the suddenly appearing young man in black warily.

"Cool--!"

Phineas and Ferb stopped using their wrenches and ran to Jiang Li with shining eyes.

"Brother, I didn't expect to see you here again." Phineas warmly extended his hand.

Jiang Li smiled and shook hands with Phineas.

Wow! A giant dinosaur!

Jiang Nian, nestled in Gwen's arms, clapped her hands excitedly when she saw the enormous Null Void Guardian in the sky. She broke free from Gwen's embrace and floated lightly in mid-air, actually wanting to fly up and grab the monster's tail.

"Hey! Little sister, it's dangerous up there!"

Phineas was startled and was about to stop him.

"Don't worry, she's much sturdier than that monster." Jiang Li waved his hand with a smile, pulling his daughter, who was flying in mid-air, back into his arms. "Niannian, this one can't be kept as a pet, she's too ugly."

"Brother Jiang Li, this monster crawled out of that purple building in the city center (Dr. Doofenshmirtz's evil building). We've built a 'Transdimensional Beast Capture Mech,' but we're still missing a bit of modification to the power core."

Phineas pointed to the huge mecha behind him, then his gaze fell on the Omnitrix on Jiang Li's left wrist.

Phineas's eyes lit up instantly.

"Hey, Ferb! I know what we're going to do today! We can use the alien energy array in the watch!"

Phineas leaned close to Jiang Li's hand, gazing at the Omnitrix as if it were a rare treasure.

"This code structure... it's a work of art! Dude, could you lend us your watch to connect to the mech? Just five minutes!"

Seeing Phineas's fanatical inventor's gaze, Jiang Li couldn't help but laugh. This was a true genius, even wanting to modify Azmuth's watch.

"I can't lend you the watch. However, I can contribute to your invention in another way."

Jiang Li patted Phineas on the shoulder and turned to look at the huge capture mech.

Now that we're on the inventors' turf, we should solve the problem the inventors do!

Jiang Li raised his left hand and pressed his thumb heavily onto the watch face.

Buzz!

With a flash of green light, Jiang Li transformed into an alien composed of black and green liquid metal, its body covered in green circuit patterns.

Galvan System, Galvanic Mechamorph.

[Upgrade (Upgrade)]!

"Wow! Liquid smart metal!" Phineas and Ferb exclaimed at the same time, with Ferb even giving a thumbs up, which is extremely rare for him.

Jiang Li, transformed into Upgrade, instantly turned into a pool of green liquid metal, like a living code, and climbed directly onto the giant mech created by Phineas and Ferb!

"System integration. Underlying logic rewritten. Weapon module fully Upgrade."

Jiang Li's announcement, delivered in a synthesized electronic voice, echoed in the backyard.

Click click click click!

Under the cover of this high-dimensional liquid metal, the originally crudely designed backyard mecha underwent a dramatic evolution!

Ordinary sheet metal was transformed into a black and green cosmic-grade alloy; ordinary plasma engines were forcibly Upgrade into antimatter thrusters.

Jiang Li controlled the Upgrade mecha, the green circuitry in his eyes emitting an extremely dazzling light.

The antimatter thrusters on the back of the mech exploded with a roar, and the massive body shot directly into the sky as if teleporting.

Sensing the threat, the Null Void Guardian opened its blood-red maw and lunged at the mech.

"Gravity capture net, launch."

The mecha's right arm suddenly opened, and a giant net made entirely of green high-dimensional energy burst forth, instantly enveloping the thirty-meter-long dimensional beast within it.

No matter how fiercely the beasts spewed their death rays, they couldn't leave even the slightest burn mark on this energy net.

Immediately afterwards, a miniature dimensional containment pod, resembling a black hole, popped out from the mech's left arm.

"Compression."

Jiang Li piloted his mecha and punched the energy net. Under the Upgrade, terrifying power, the enormous beast was forcibly compressed into a red glass ball, which then fell precisely into the containment chamber.

The battle ended in less than ten seconds.

The mecha landed smoothly in the backyard. The green liquid metal peeled off the mecha, and Jiang Li transformed back into the young man in black.

On the tree, Agent P (Perry) silently removed his hat, gave Jiang Li an extremely gentlemanly agent salute, and then slipped away without a sound.

"That's awesome! Dude! You just increased the efficiency of our plasma generator by 30,000 times!" Phineas excitedly ran over, while Ferb frantically took notes beside him.

"Just a little Upgrade trick."

Jiang Li toyed with the glass ball that sealed the monster in his hand, then casually tossed it into the storage space of the Omnitrix.

Just then, hurried footsteps came from the wooden door of the backyard.

Phineas's sister, Candace, stormed in, looking frantic, her phone in hand.

"I've got you guys! Phineas! Ferb! What kind of monster mechs have you built in the backyard this time! I'm calling Mom right now..."

However.

A hint of a smile flashed in Jiang Li's eyes as he lightly slid his finger across the watch face.

Buzz.

The highest level of privileges was quietly activated.

The enormous mech in the backyard, along with all traces of the battle, vanished into thin air in an instant, transforming into an extremely small stream of data. The backyard was restored to its pristine state.

Candace pointed to the empty backyard, her eyes practically popping out of their sockets.

"But... but there was definitely such a big one just now..." She grabbed her hair in despair.

"Hey, Candace. We're discussing microphysics with Jiang Li." Phineas shrugged innocently.

"Alright, the vulnerability has been patched."

Jiang Li took Gwen's hand and used his other hand to pick up Jiang Nian, who was chasing butterflies on the lawn.

Jiang Li looked at Phineas and Ferb, and waved with a smile.

"Have a wonderful summer vacation. Now, it's time for me to go on my vacation too."

The green portal lit up again.

This time, there were no alarms or obstacles.
