Xiao Han's Super Vision penetrated the skyscrapers of New York, locking onto a chaotic street.
Tony Stark, wearing the latest model of his armor, was locked in fierce combat with a heavy armored machine about three meters tall.
Energy beams exploded on the street, and passersby screamed and scattered.
"Looks like our billionaire is having fun." Xiao Han's lips curved slightly, and he bent his knees.
Bang!
The black figure quickly ascended, Xiao Han streaking across the sky at an extreme speed.
The crowd on the street looked up and gasped.
"Is that... Superman?!"
Inside Tony's armor mask, Jarvis's voice sounded: "Sir, detecting a high-speed approaching target, energy signature matches, it is Mr. Xiao."
"Finally back." Tony fired a repulsor blast at the enemy armor's chest, taking a moment to glance at the sky.
"Just in time for him to see my new toy."
The black figure stopped abruptly in front of the two in a manner that defied the laws of physics.
Xiao Han hovered in the air, the golden patterns on his black battle suit shining brightly in the sunlight.
"Need Superman's help?" Xiao Han raised an eyebrow, looking at Tony.
The enemy armor seized the opportunity, throwing a heavy punch towards the back of Xiao Han's head.
The fist stopped abruptly a few centimeters from his hair, as if it had hit an invisible wall.
Tony shrugged: "Thanks, but I'm just testing the performance parameters of the new armor."
He pointed at the opposing armor, "A naughty villain."
Xiao Han shook his head: "No need to test it, it'll need upgrading soon."
"What do You mean?" Tony's mask lifted, revealing a confused expression.
Xiao Han didn't answer, turning to face the enemy armor.
The behemoth seemed to sense the threat, and all its weapon ports lit up simultaneously with charging light.
"Goodbye." Xiao Han waved his right hand lightly, and a golden rune flashed in the air.
A swirling azure spatial vortex suddenly appeared beneath the armor, and the entire machine was instantly swallowed.
The next second, a sharp whistle came from high altitude, the armor was in free fall from three thousand meters up.
"Jarvis! Track target!" Tony exclaimed.
Xiao Han had already shot up into the sky, instantly catching up to the falling armor.
He delivered a whip kick, and the armor shattered into pieces with a loud bang.
Just as the fragments were about to scatter, Xiao Han drew a circle with one hand, and another portal appeared, swallowing all the wreckage.
Three seconds later, he gently landed back on the ground, carrying the unconscious thug, and tossed him to the stunned Police.
"Who... who are You?" The Police stammered, his hand on his holstered gun but not daring to draw it.
Xiao Han smiled slightly: "You can call me Superman."
Tony landed beside him, his mask rising again: "Wait, what was that just now? magic? Jarvis shows that armor has disappeared!"
"Teleported to your private warehouse." Xiao Han patted Tony's shoulder.
"Asgardian magic."
Tony's eyes lit up instantly: "magic?"
"Let's talk back at the tower." Xiao Han glanced at the growing crowd and passersby holding up their phones.
"Unless You want to be on every headline tomorrow."
The two shot up into the sky, leaving behind a street filled with gasps of astonishment.
Several children jumped excitedly, shouting: "It's Iron Man and Superman! They're working together!"
In the top floor lab of Stark Tower, Tony eagerly examined the armor wreckage that had appeared out of nowhere.
"This is incredible!" He picked up a twisted metal plate.
"Instant teleportation, zero energy loss, no spatial distortion, this completely violates known physical laws!"
Xiao Han stood by the floor-to-ceiling window, overlooking the New York sunset: "The Asgardians call it Heimdall's blessing, essentially using World Tree energy for spatial folding. I saved Thor and took a trip to Asgard."
Tony turned sharply: "Asgard? Are You talking about the place from mythology…?"
"Exactly what You're thinking." Xiao Han nodded.
Tony's eyes widened, and the metal plate in his hand clanged to the ground: "Wait, I'm not quite processing this, You just said... God? Asgard?"
He gestured dramatically, "You mean that guy from Norse mythology who flies around with a hammer?"
"Odin, Loki, Thor, all the ones You're thinking of are there." Xiao Han explained with a smile.
"Is this… real? Am I not on Earth? Why have myths become reality?" Tony still couldn't quite believe it.
Xiao Han took out a large box from his System space: "Much more real than You imagine."
He opened the box, and inside lay a piece of metal glowing with a faint blue light, "This is uru metal given by Thor, the material used to forge artifacts in Asgard."
"Okay, I'm not surprised anymore." Watching Xiao Han conjure items out of thin air again, Tony took a deep breath.
He cautiously poked the metal with his finger, and Jarvis immediately issued an alert: "Detecting unknown element, atomic structure abnormally stable, Sir, this completely violates the periodic table!"
"So... those myths are all true?" Tony grabbed a nearby whiskey and took a big gulp, asking again.
"Odin? Loki?"
"More or less." Xiao Han pointed at the metal.
"However, they prefer to call themselves a higher civilization rather than gods.
Thor is just an alien prince who likes to swing a hammer, it's just that their civilization developed earlier."
Tony suddenly became excited: "What about their technology? Weapons? Energy? Transportation?"
"That's the first surprise I have for You." A trace of amusement flashed in Xiao Han's eyes.
He pressed a hidden pattern on the metal box, and the box suddenly disintegrated into countless nanoscale particles, reassembling in the air into the shape of a miniature war hammer.
"Asgardian nanotechnology." Xiao Han looked at Tony's shocked expression.
"More advanced than your Mark series."
Tony leaned in to observe like a child seeing a new toy: "This... this is impossible! Nanoscale self-reorganization requires unimaginable computing power and energy control…"
"Plus a bit of uru metal's magic properties." Xiao Han snapped his fingers, and the war hammer turned back into the box.
"It took me a little time to figure out the principle. The good news is, I've reverse-engineered and simplified a version suitable for Earth materials."
Tony suddenly grabbed Xiao Han's shoulder: "You have to teach me! Name your price!"
"That's the second surprise." Xiao Han again took out a data chip from the System space.
"All the technical parameters are here, including the fusion plan for uru metal and Earth alloys. Enough for You to upgrade your Mark armor into nano-armor, and help me build a set too."
Tony snatched the chip like a treasure, his hands trembling: "Jarvis! Scan immediately! Start holographic modeling!"
Blue light scanned the chip, and a complex molecular structure diagram was immediately projected in the center of the lab.
Tony frantically manipulated the holographic image like a madman: "This energy conduction method...! And this reorganization algorithm… Xiao! They are geniuses!"
Xiao Han leaned against the console, watching Tony fall into technical frenzy: "A word of caution, uru metal needs a specific energy frequency to activate.
I think You'll need to modify your reactor output mode, remember to upgrade the energy core first."
