Phineas and Ferb's Summer Vacation Invention

"Waaaaah!"

The piercing, highest-level alarm at the Avengers Compound instantly shattered the relaxed barbecue party.

Tony's Mark 50 Nanotech Armor was fully deployed in a fraction of a second. Steve kicked over the barbecue grill and caught the Vibranium Shield that popped out from under the table. Thor threw down his wine glass and summoned Mjolnir with one hand, instantly filling the sky with dark clouds.

"Friday, retrieve the deep space radar images!" Tony's voice behind his mask was extremely grave.

A holographic star map was projected onto the lawn.

Not far from Jupiter's orbit, a colossal object, comparable in size to the Moon, is hurtling toward Earth at a speed that defies the laws of physics.

"No conventional plasma wake, no wormhole readings..." Tony stared intently at the screen, cold sweat breaking out. "This thing looks like it's flying with a power engine that we can't understand at all."

Who cares who he is?

Thor, his body crackling with azure lightning, declared, "Dare to come to Earth? I'll teach him Mjolnir!"

"Calm down, everyone."

Jiang Li dusted off the cumin powder on his hands and walked to the holographic screen.

He looked at the round, bizarrely shaped "lunar-class warship" and raised an eyebrow slightly. In his higher-dimensional perception, this thing not only lacked any murderous aura, but instead exuded an extremely absurd... aura of joy?

"You guys stay at base and protect the barbecue so the dogs don't steal it. I'll go up and check first."

Bang!

A muffled thud echoed from the lawn. Jiang Li didn't even transform; relying solely on his Krypton physical strength, he became a black afterimage that broke the sound barrier, hurtling straight into the atmosphere.

A few seconds later.

Earth's near-Earth orbit.

Jiang Li hovered in the vacuum of space. And directly in front of him, the "lunar-class warship" that had triggered the Avengers' highest alert finally revealed its true form.

Jiang Li looked at the scene before him, and his eyes twitched violently twice.

This is hardly a Star Destroyer.

This is an enormous, brightly colored amusement park filled with twisted circular tracks and giant water slides—a cosmic-level mega-amusement park!

The main structure of the amusement park was painted in the shape of a green platypus wearing a brown fedora!

"This is...!" Jiang Li rubbed his temples.

Jiang Li flashed through the mysterious "air shield" surrounding the amusement park and landed on the deck of the amusement park's main control room.

There was no fully armed alien army on the deck.

There are only two children.

A triangular head with a skeletal structure that is completely out of place in humans, red hair, and wearing a striped T-shirt.

The other one had a rectangular head, green hair, wore high-waisted pants, and was taciturn.

Beside them lay a pet platypus, chewing on a wrench.

"Ferb, I told you that if we tightened the screws on the Quantum Differential a little, we could break through the dimensional barrier of Danville!"

The boy with the triangular haircut held a blueprint and excitedly pointed to the blue Earth in the distance.

"Look, that planet is so beautiful! I bet its water park is amazing!"

The boy with the long, rectangular hair Ferb, pushed up his glasses, didn't say anything, but silently gave a thumbs up.

Jiang Li stood behind them, listening to the familiar conversation, and remained silent for a full three seconds.

He never imagined he would encounter these two "summer vacation devils" —Phineas and Ferb —who could completely outwit physics.

"Ahem." Jiang Li cleared his throat.

Phineas turned around and saw Jiang Li. Instead of being afraid, he waved to him very politely and energetically.

"Hi! Are you an astronaut from this universe?"

Phineas stepped forward, extending his hand familiarly. "I'm Phineas, and this is my younger brother, Ferb. While we were test-driving the newly invented ' Tri-State Area Ultimate Interdimensional Roller Coaster,' our GPS was accidentally knocked off course by a flying pigeon. Excuse me, where are we?"

Jiang Li looked at the outstretched hand, a helpless yet amused smile curving his lips.

He extended his hand and shook hands with Phineas.

"This is the Marvel Universe, New York."

Jiang Li pointed to the amusement park beneath his feet, which was bigger than the moon, and asked, "Did you two build this thing?"

"Yes!"

Phineas patted the control panel beside him with a proud look, "It's summer vacation, so we have to find some fun. This morning we spent about three hours modifying some old car parts and a few microwave ovens from the backyard to build this. I have to say, this anti-gravity slide in space is so cool!"

In three hours, using a microwave oven and scrap metal, they built a transdimensional space station the size of the moon.

Jiang Li sighed.

That's what you call the quality of an animated film's protagonist. If Tony Stark heard that, he'd probably want to smash his head against a wall on the spot.

"Jiang Li!"

At that moment, Tony's extremely anxious voice came through the communicator on Jiang Li's wrist.

"Have you made contact with the enemy ship? Deep space scans show that the ship is filled with high-energy reactions that we can't analyze! I've locked onto the orbital cannon, do you need fire support?!"

On the other end of the communicator, Steve and Thor were already preparing to board the Quinjet.

"Tony, all-clear. Retract the railgun."

Jiang Li looked at Phineas and Ferb, who were squatting on the ground feeding nuts to the platypus, and said into the communicator with extreme annoyance.

"Jiang Li, are you being controlled?" Tony's tone tightened.

"Control my ass."

Jiang Li sighed. "They're two elementary school students."

"What?!" Tony's incredulous voice crackled through the communicator. "A primary school student? Piloting a warship the size of the moon?"

"Yes. And their warship was modified from a microwave oven," Jiang Li added casually.

There was a deathly silence on the other end of the communicator for ten seconds.

"Tony? Popsicle?" Jiang Li called out twice.

"Ignore them, Tony seems to be smashing things in the lab and muttering something about 'impossible laws of physics'," Natasha's voice came through, tinged with suppressed laughter.

Jiang Li cut off the communication and turned to look at Phineas and Ferb.

"Listen up, guys," Jiang Li pointed to the platypus (Agent P) that was secretly putting on a secret agent hat, "While I welcome you, your amusement park is too big. If it were to stop in Earth's orbit, it would cause a tsunami."

"Oh! Sorry, we didn't consider the issue of gravitational tides!"

Phineas slapped his forehead, "Ferb, activate the ' Portable Folding Compression Program '!"

Ferb nodded, took something that looked like a car remote control from his pocket, and pressed a button.

Swish!

Under Jiang Li's watchful gaze, this cosmic amusement park, larger than the moon, shrank out of thin air in less than a second, without any energy fluctuations or mass explosions.

Finally, with a "thud," it turned into a toy ball no bigger than the palm of his hand and landed in Ferb's hand.

"Alright! Now it doesn't take up any space!" Phineas clapped his hands in satisfaction. "Big brother, can you take us to try the ice cream from your universe?"

Watching this scene, Jiang Li could only give a thumbs up to this "humorous physics in an animated film".

"Okay." Jiang Li smiled.

Let's go, I'll take you guys out for some barbecue.
