Stark felt a chill run down his spine; he knew Yan was right.
Judging from the strength Yan just displayed, he really wasn't entirely confident he could stop his opponent.
"Alright, I'll trust you for now. But before I help you, you have to tell me what you want to do with these technologies."
Stark decided to probe Yan's intentions first; he didn't want to get unwittingly dragged into an unknown mess.
Yan narrowed his eyes slightly and remained silent for a moment.
"This has nothing to do with you! All you need to know is that what I'm doing won't affect the world, at least not you or your people."
Tony Stark frowned slightly upon hearing Yan's reply.
He still harbored doubts about the mysterious man's motives, but for now, it seemed there was no better option.
"Alright, since you put it that way, I'll trust you this time. But before we start working together, you have to do me a favor."
Tony Stark gestured around.
"Look, the spatial lockdown in this building hasn't been lifted yet. I don't want to be trapped here forever. There are still many things waiting for me to deal with outside."
Yan glanced around and nodded slightly. "This is nothing."
After saying that, he once again mobilized the spatial power within his body, and his hands moved rapidly in the air, drawing mysterious trajectories.
As Yan moved, the surrounding space seemed to undergo some subtle change.
The previously sealed-off space began to show signs of loosening.
Gradually, the oppressive feeling of being locked up dissipated.
Tony Stark also confirmed through his armor's detection system that the spatial lockdown had been lifted.
"Wow, that's amazing! How did you do that? This isn't like any technology I'm familiar with."
His curiosity was completely piqued, and he maneuvered his armor to circle around Yan, trying to find some clues from Yan's movements and expressions.
Yan's lips curled into a smile. "Chakra, it contains endless mysteries and possibilities."
Tony Stark was clearly not satisfied with this vague answer.
But he also understood that now was not the time to get to the bottom of things.
"Alright, whatever power it is, as long as it helps me."
"Next, let's discuss the specifics of our cooperation. What specific technical information do you need from me?"
Upon hearing that it was a serious matter, Yan's eyes became focused, and he slowly said, "I need your technical data in three areas: energy utilization, mechanical manufacturing, and artificial intelligence."
Tony Stark frowned upon hearing this. "What do you need all this for? Don't get me wrong, having a goal will speed up the research process."
Yan crossed his arms, remained silent for a moment, and then said, "Everything is in service of space travel technology."
"Space travel? I can't do that right now."
"That's not something you need to worry about. I'll find the technology myself. These are just supplementary tools."
Tony Stark raised an eyebrow after hearing this. "Okay, you're the boss now, you call the shots."
In the following days, they busily carried out their research work in the Stark Tower.
Yan demonstrated the unique properties and uses of chakra to Tony Stark without reservation.
Tony, with his exceptional technological talent, attempts to find a point of convergence between these energy phenomena and modern technology.
After several attempts, Tony successfully extracted a small, relatively stable sample of chakra from Yan.
He was overjoyed and immediately placed it in his meticulously designed high-tech testing instrument.
Using various advanced analytical methods, we attempt to analyze the energy structure and execution mechanism of chakra.
Meanwhile, Yan, seeing that the research was gradually getting on track, began to think about something else— Vibranium.
Based on its properties, Vibranium is ideally suited as a material for spacecraft, especially for protective layers.
It has high hardness and can withstand various physical impacts and collisions.
It is heat resistant and can withstand extreme temperature changes.
It is impact-resistant and can absorb and disperse impact forces.
Lightweight design: Although Vibranium is extremely strong, it is relatively light, which helps reduce the weight of the spacecraft and improve fuel efficiency and flight performance.
Two days later, while Tony was engrossed in his chakra research, Yan suddenly narrowed his eyes and the spatial power around him surged once more.
He suddenly tore open the space in front of him with both hands, instantly creating a spatial rift leading to an unknown place.
Before Tony could react...
Yan then left with the words, "I'm going to retrieve some things that are crucial to our plans. I'll be back."
With that, he vanished into the spatial rift in a flash.
Tony was stunned by this sudden turn of events, and he tried to track Yan's whereabouts through the various surveillance devices in the base.
However, Yan's spatial traversal technology was clearly beyond his comprehension, and all tracking methods yielded no results.
"Where did this guy go? What is he going to do?" Tony was filled with doubt and worry.
Yan's strength is unfathomable; if his actions cause unforeseen consequences...
Not only would their cooperation fall apart, but the entire world could be in danger.
At that moment, Yan arrived above Wakanda in an instant through a spatial rift.
He looked down upon this mysterious and bountiful land, with only one goal in his mind— Vibranium.
Using his spatial abilities, he easily bypassed Wakanda's outer defense system and silently infiltrated the core area where Vibranium was stored.
As Yan stepped into the treasure trove filled with Vibranium, an uncontrollable burning desire shone in his eyes.
However, his undisguised actions triggered Wakanda's highly secretive alarm network.
In the blink of an eye, Black Panther led Wakanda's most elite warriors, rushing in from all directions like a whirlwind, instantly surrounding Yan.
Black Panther's eyes burned with vigilance and rage. "Outsider, how dare you trespass on my clan's sacred ground and steal Vibranium! You will not escape today!"
Yan's lips curled up slightly, revealing a disdainful sneer.
The spatial power around him surged like a raging tide, and the space around his body fluctuated violently, as if it were an indestructible transparent armor.
Countless attacks landed on Yan's body, yet they failed to cause the slightest ripple.
Seeing that conventional attack methods were ineffective against Yan, the Wakanda warriors drew upon a variety of high-tech weapons and their unique, long-standing combat skills.
For a moment, the dazzling beams of energy mingled with the cold glint of the weapons.
The entire treasure vault was in chaos.
But Yan remained calm and composed, quickly Hand Seals.
In Setsuna, a powerful and vigorous chakra force surged out from his body, like an invisible storm, instantly blasting the warriors who approached him several meters away.
