Just arrived at Marvel, the system rewards the Man of Steel

When the last piece was removed, he found a blueprint in his palm, Howard Stark's final gift to his son.

"Dad..." Tony's voice was a little choked, but was soon interrupted by the alarm in the laboratory.

"Sir, a high-speed approaching target has been detected."

Before Tony could react, Xiao Han was already standing behind him.

"A new element has been found."

Tony turned around abruptly, subconsciously hiding the blueprint behind his back, and then laughed at himself: "There's no point in hiding it for you, is there?"

Xiao Han's eyes fell on the design: "Your father is a genius."

"Yeah, it's a shame he's better at leaving puzzles than company." Tony shook the blueprint, "But this does solve my problem."

At three o'clock in the morning, the underground laboratory of Stark Industries was brightly lit.

Tony, wearing an oil-stained T-shirt, was debugging a particle accelerator.

Xiao Han stood aside, giving key suggestions from time to time.

"That won't work. The proton beam will diverge." Xiao Han pointed to a parameter and said, "Increase the magnetic field strength by 12%."

Tony frowned, then adjusted his brows: "You even understand quantum physics?"

"I just learned it an hour ago." Xiao Han answered casually.

As the machine roared, a beam of blue light flowed through the vacuum tube.

Tony held his breath and watched the data curve on the detector gradually stabilize.

"Success!" He grabbed the new element with a triangular glow and cheered like a child. "Jarvis, prepare for the transplant!"

Xiao Han pressed his shoulders: "Not now, you are too tired."

"No, no, no... I..." Tony's words stopped abruptly because he found that his feet were off the ground and Xiao Han directly picked him up.

"A human who hasn't slept for 48 hours isn't suitable for delicate surgery," Xiao Han said without question. "Rest for six hours, and I guarantee everything will be ready when you wake up."

Tony wanted to protest, but he suddenly felt overwhelmed by sleepiness.

In the last moment before he fell into darkness, he vaguely realized that the alien was using some kind of biological force field on him.

Six hours later

Tony Stark woke up in the blinding white light, the smell of disinfectant irritating his nostrils.

He subconsciously touched his chest, and what his fingertips touched was no longer a cold metal ring, but a brand new reactor.

Emitting a purer blue light than ever before.

"The operation was successful."

Tony turned his head sharply and saw Xiao Han standing in front of the biological scanner, with a 3D model of his chest cavity displayed on the holographic projection.

Surgical instruments were neatly arranged aside, but the most striking thing was that all the equipment bore obvious signs of modification.

"You...operated on me?" Tony's voice was a little hoarse. "Here? Without a medical team?"

Xiao Han turned off the projection and walked to the bedside: "Your vital signs are stable. The new element has perfectly integrated with the myocardial tissue, and the symptoms of palladium poisoning have disappeared."

Tony looked down at his body. There were no surgical incisions or sutures, as if he had never undergone open-heart surgery.

This medical technology...

"Wait," Tony said, realizing something, "you modified my medical equipment?"

Xiao Han picked up an ordinary surgical robot: "Added some control modules."

His fingertips glowed faintly as he lightly traced the metal surface, revealing the completely reconstructed circuitry within.

Tony's breathing became rapid.

As an engineer, he knew all too well what this meant.

This man who calls himself Superman not only possesses godlike power, but also possesses superhuman wisdom.

"I have to say, you're great." Tony finally breathed a sigh of relief. He decided not to dwell on this issue anymore.

Tony sat up on the medical bed and moved his shoulders, feeling the new source of energy in his chest.

The blue light filtered through the fabric of the shirt, standing out prominently in the dim lab.

"How does it feel?" Xiao Han handed over a cup of amber liquid.

Tony took the cup and sniffed it, his eyebrows raised. "Macallan 55? Where did you find that?"

"Your personal wine cellar." Xiao Han raised the corner of his mouth slightly, "But now it has been improved and can accelerate cell repair."

Tony took a sip and his eyes lit up. "Damn, that tastes! What did you add to that?"

"Some kind of substitute." Xiao Han walked towards the operating table on the other side of the laboratory, "It can temporarily enhance the efficiency of nerve conduction."

Tony shook his glass and suddenly said seriously, "Why did you help me to this extent? That surgery, those transformations, this is beyond the scope of the transaction."

Xiao Han turned his back to him, tapping his fingers on the holographic keyboard: "15% of the shares deserve better service."

"Bullshit." Tony put down his glass. "You know the market value of Stark Industries. Even without you, I can still..."

"Found it." Xiao Han interrupted him and took out a test tube from the freezer.

The light blue liquid glowed with a strange luster under the light, and there seemed to be countless tiny points of light flowing inside.

Tony's scientist instincts immediately kicked in: "What is this?"

"Improved Super Soldier Serum." Xiao Han placed the test tube under the optical microscope. "Based on Dr. Erskine's prototype, but with all the side effects removed."

Tony leaned in for a closer look, and Jarvis immediately projected the analysis data onto his retina: "The molecular structure is 37% more complex than the version in the SHIELD archives... These protein chains..."

"The strength increase is 2.5 times that of the original version, the metabolic rate increases by 400%, and the bone density..." Xiao Han paused.

"Enough to give you a mere scrape after falling from a thirty-story building."

Tony straightened up, his expression becoming serious. "You copied the Super Soldier Serum? In just a few days?"

"It's not exactly a copy." Xiao Han turned the test tube.

"I rewrote the entire genetic sequence. There will be no side effects like the Red Skull, nor will it change the user's personality traits."

Chapter 9 Nick Fury

The laboratory fell into a brief silence.

Tony's eyes moved back and forth between the test tube and Xiao Han, finally settling on the other's calm face.

"Why?" he asked softly. "This is far beyond the scope of our agreement."

Xiao Han put the test tube into a portable cooler and pushed it in front of Tony: "Because, this is very interesting."

Xiao Han made up an excuse casually, which he decided when Tony was unconscious.

He suddenly wanted to see what impact Tony Stark, who possessed a physique beyond ordinary people, would have on Marvel?

Of course, the most important thing is that as a Superman, he will definitely get the Silver Superman template from the system in the future.

Then, traveling around the world is his goal.

As the Marvel world is his base, he must have a strong ally to watch over him.

And now, Tony is the best choice.

"Interesting?" Tony frowned. "What's interesting?"

"That set of armor." Xiao Han made up an excuse.

"In other words, you could have mobilized all your resources to research countermeasures. But you chose to trust."

Tony opened his mouth, but was momentarily speechless. He looked down at the cooler and suddenly smiled. "So this is your return gift? To make me Captain America 2.0?"

"3.0." Xiao Han corrected, "And you can choose not to use it. It's just a safety precaution. Besides, this is one of the surprises."

Tony picked up the cooler and felt the cold touch. "Will I become as righteous as Rogers after the injection?"

"No." Xiao Han shook his head. "It will only enhance your physical fitness. Willpower, character, and moral values ​​are all determined by you."

Tony put the refrigerator into the safe under the workbench, and the fingerprint lock made a beeping confirmation sound.

When he turned around, that cynical smile returned to his face. "So, now we're real partners?"

"If you like." Xiao Han walked towards the floor-to-ceiling window, and the morning light of New York began to dye the skyline red.

"But I recommend you get a comprehensive physical before the injection. Although I've eliminated any side effects, everyone's constitution is different."

"I know, I know. You're as talkative as my dad..." Tony waved his hands and suddenly remembered something.

"Wait, you said this was one of the surprises? There were other gifts?"

Xiao Han raised a mysterious smile and said, "I can only show you that after you use the serum."

Tony narrowed his eyes. "I want to know now."

"Patience is a virtue, Mr. Stark." Xiao Han began to float and fly out of the window.

"Remember to complete the injection within 72 hours, otherwise the active ingredient will degrade."

"Hey! Wait!" Tony reached out to grab him, but Xiao Han had already flown away.

Xiao Han's last message echoed in the laboratory:

"See you in three days. I hope to see an upgraded version of you then."

Tony stood there for a long while before shouting to the empty laboratory: "Jarvis! Prepare for analysis."

"Okay, sir." Jarvis paused, "Do you want me to contact the medical department now to prepare for a physical examination?"

Tony stared at the safe, his fingers drumming unconsciously on the workbench.

Finally, he took a deep breath, “Contact Pepper first… No, wait.

First, retrieve all available information on the Super Soldier Serum, especially Dr. Erskine's original research notes from 1943."

The holographic screen unfolded in front of him, but Tony's eyes couldn't help but drift towards the safe.

A long-lost, almost childlike curiosity and anticipation beat in his chest.

He hadn't experienced this feeling for a long time since his father passed away.

Outside the window, sunlight penetrates the clouds, gilding the Stark Tower.

Tony was still standing in front of the French window in a daze when Jarvis's voice suddenly broke the silence of the laboratory.

"Sir, an unauthorized landing has been detected on the top landing pad."

Tony raised an eyebrow. "Media helicopters? Tell them this is private airspace."

"It's not the media, sir." Jarvis' tone was rarely wary. "The identification signal indicates it's a S.H.I.E.L.D.-built Quinjet."

Tony's expression instantly turned cold.

He turned and walked towards the workbench, quickly pushing the refrigerator into the secret compartment, and the serum molecular structure diagram on the holographic screen disappeared.

"Activate the defense protocol and lock all research data on Xiao." He whispered the order while straightening his wrinkled shirt.

"Let our one-eyed guest in."

The moment the elevator door opened, Nick Fury strode into the laboratory, his black leather jacket fluttering behind him, and he scanned the surroundings with his one eye.

He was followed by two fully armed agents, who were standing guard at the elevator entrance vigilantly.

"Stark." Fury's voice was low and direct. "We need to talk about your new friend."

Tony leaned against the operating table, picked up a glass of whiskey, and pretended to be nonchalant. "Nick, you came to my house in person so late at night, are you looking to invest in my clean energy project?"

Fury ignored his teasing and walked straight to the central holographic projection area.

He flicked his wrist, and a miniature projector fell onto the table, immediately displaying the surveillance footage of a Queens bank from a few hours ago.

The whole process of Xiao Han, wearing black armor, easily subduing the mutant.

"Explain, Stark. Who is this man wearing the armor you designed and possessing supernatural powers? Don't tell me he's Superman." Fury stared at Tony with his one eye.

"There's no record of him in the SHIELD database."

Tony took a sip of his drink and his eyes lingered on the screen for a moment: "You guessed it, he is Superman."

After a pause, Tony looked at Fury, who still had a serious expression on his face. "Well, this is a trade secret, Nick. Stark Industries' new security consultant, that's all."
