Don't let Stark's usual carefree demeanor fool you. He takes this stuff seriously. That's why he's been holed up in his underground workshop for months, building all those suits of armor.
But even those impressive suits are limited to Earth. They're useless in a space-level war, which is what the future holds.
That's why Stark is so anxious right now.
"So, do you have a solution?"
Stark asked eagerly. His biggest problem right now was energy.
The most convenient and powerful energy source in the world is the Arc Reactor in his chest. But even that wasn't enough to support Stark's desire to protect the whole world.
Even if the energy is powerful, it's only for Earth. It can't be used for space combat. Only even more powerful energy can do that.
Stark stared intently at Han Yu, trying to see if he was just making up stuff.
But the latter's handsome face, with slightly narrowed eyes and a slightly raised corner of his mouth, made him look extremely relaxed and confident, not at all avoiding Stark's gaze.
"Price? Tell me, how much will your technology cost to sell to me? One hundred million dollars? One billion dollars? Ten billion dollars? Or a hundred billion dollars? Just name your price, I can afford it!"
Seeing Han Yu's hesitation, Stark thought he was considering the price, so he excitedly offered the price he could accept.
Han Yu wasn't very surprised by his excited appearance, but rather thought it was normal.
Han Yu rubbed his chin, what should he ask for?
Money? He didn't need it. The thirty billion Silver taels he got in Konohagakure could be converted into any currency of any world through the Shop system. Converted, Han Yu's account now had nearly three hundred million dollars in assets.
Although this money couldn't be considered too impressive on Earth, it could also meet Han Yu's daily needs. After all, he wouldn't be like other young masters who spent money like water every day. He planned to become the man standing at the top of all the heavens and myriad worlds.
Naturally, it was impossible for him to indulge himself just because he had some money.
"What should I get?"
Han Yu was momentarily unsure. Should he get Iron Man's armor? An Arc Reactor?
For him, who had just obtained the Green Lantern Ring, these things, which could be called artifacts on Earth, held no appeal.
Just as Han Yu was fretting, the voice of A Shop suddenly echoed in his mind.
"Extra mission triggered, 'Recruit a Shop Assistant'!"
Han Yu was taken aback, a glimmer of excitement flashing in his eyes. An extra mission had triggered?
Extra missions were the missions with the richest rewards among those issued by the system!
The advantage of extra missions was that the mission rewards were not fixed; the higher the completion, the better the rewards obtained, and the lower the completion, the rewards would naturally be reduced.
But Han Yu was a "cheat player." As a transmigrator, he knew the Marvel stories that would follow like the back of his hand. The moment he saw this mission, he already had a person in mind.
That's the super robot, Ultron!
"Nice!"
As soon as this task appeared in his mind, Han Yu made up his mind. He chuckled and said, "I don't want your money. How about this? You help me make a game. I'll provide the plan, and you take care of everything else."
This request stunned Stark. What kind of request was this?
The thing he wanted, speaking seriously, wasn't something that could be measured by money. Yet Han Yu said the price for it was just to have him help make a game?
Thinking about it, a look of extreme rage flashed across Stark's face, and his entire mood was instantly ignited.
Taking three steps in one, he rushed directly in front of Han Yu, grabbed his collar, and roared.
"Are you f*cking kidding me? I don't have time to joke with you. Do you even have the thing or not!"
This shout was very frightening. Stark's face turned red because of his anxiety. You could see that he was really anxious.
"Let go of your hand."
A sentence that didn't sound good or bad came from Han Yu's mouth. It seemed to be the sound coming from his mouth, but Stark felt the sound was coming from all directions.
A presence that didn't match his age at all emanated from Han Yu, causing Stark to reflexively release his grip.
Stark swallowed hard, a hint of fear flashing in his eyes. He actually felt a kingly aura emanating from this young man, who was a decade or two younger than him.
Han Yu straightened his clothes, his voice still carrying a hint of a smile, but it held no warmth.
"Last chance. Decide for yourself whether you're willing. I won't force you."
This was indeed Han Yu's thought. After all, he was a transmigrator and didn't want to constantly jump between different worlds. If he didn't bring some games from his previous life, how could his life be considered perfect?
Han Yu could obtain the game plans from the Shop system, but he'd need the cooperation of a local game company to make the games.
He believed that once the games were made and released, he would definitely become one of the richest people in the world!
After all, the market for games was terrifyingly huge. Moreover, in this world of gods and ghosts, a good game could effectively help people relax.
Stark looked at Han Yu's smiling face. Even when facing him, Han Yu didn't back down at all. This kind of presence wasn't something a normal person in their twenties should have.
"Alright, I agree," Stark hesitated for a moment before agreeing. He didn't think the condition was too harsh; instead, it was too simple, so simple he couldn't believe it was all that was required.
"That makes things easier."
Seeing the other person agree, Han Yu immediately conjured several strands of visible, tangible green energy. It emerged from his palm, slowly condensing.
Even Tony Stark, a member of the Avengers, widened his eyes. He had never seen anyone able to materialize energy and manipulate it so smoothly.
After half a minute, this green energy transformed into a crystal-clear green ring, similar to the Green Lantern Ring on Han Yu's finger, and floated in Han Yu's palm.
"This is what you wanted. Take it."
Han Yu spread his fingers, and the ring floated over under his control.
Stark quickly opened his hands, allowing the ring to settle into them.
"This, what is this?"
Stark was puzzled. The method of using energy to condense an object into a ring shape with a simple gesture was truly mysterious. He didn't dare just take it.
"This is a Green Lantern Ring. You'll understand the specifics, and the energy it contains, when you go back and study it," Han Yu said with a smile.
As one of the artifacts of the DC universe, even a sub-ring would contain a surprising amount of energy for Stark.
Stark clutched the Green Lantern Ring tightly and said to Han Yu very seriously, "If this is useful, just let me know if you need anything in the future. I'll do my best!"
Before leaving, he asked for Han Yu's phone number and left a bank card, saying there were three billion US dollars in it for Han Yu to use freely.
After speaking, he immediately bid farewell to Han Yu and rushed towards the Avengers Tower. He was already eager to study the ring and discover its secrets.
Han Yu gestured with his hand, and the bank card flew into his hand, held in place by invisible mental energy, floating in the center of his palm.
"Good luck, Stark. Whether I can complete my task depends on you."
On the other side.
Stark sped all the way back. In just ten minutes, he was back at the Avengers Tower. He immediately went to his workshop and began to study the green ring he'd obtained from Han Yu.
"Jarvis, perform a comprehensive scan of this ring and compare it to the Arc Reactor I'm currently using."
"Yes, sir," the artificial intelligence Jarvis replied.
Stark stared intently at the screen in front of him, watching the data constantly merge, his expression changing.
"Sir, the calculations show that the energy intensity of this ring exceeds that of your current Arc Reactor, and could even replace it!"
"Completely replace it?"
Stark's eyes widened as he stared at the data on the computer. He had never imagined finding his solution in a small shop.
Unconsciously, Stark's gaze drifted to a white business card placed to the side. The content was very simple, only two lines.
A Shop.
Han Yu.
This business card had suddenly appeared on Stark's desk. He never brought such things down to his underground workshop. He checked the recording in the workshop.
The business card had appeared on the desk without any warning.
