"Young man, are you having fun in my world?" Stan Lee looked at Lin Yu with a kind smile, but a strange light flashed in his eyes.
"Happy," Lin Yu faced Stan Lee calmly and showed a sincere smile.
"But young man, you should not be here," Mr. Stan Lee said with a helpless smile.
"Why?" Lin Yu asked, confused. "Are you afraid I will disturb the direction of the story? But even if I completely change the history here, is it not easy for you to restart the universe? Does your group of Celestials not do this often? Are there not countless worlds in your universe? Why not just let me play in this one?"
"..." Mr. Stan Lee shook his head and pointed behind Lin Yu. "He will not agree."
The moment Mr. Stan Lee pointed, a strong golden light shone from behind Lin Yu. Lin Yu turned his head and saw a white figure, radiating white light and with no face, standing there.
"What?! TOAA?!" Lin Yu looked at the being and cried out in surprise.
"You do not belong here," said the being, TOAA, its voice as calm and emotionless as still water. "So please leave." As a conceptual existence, it had no feelings, only absolute reason.
TOAA, the One Above All, overrides everything in the entire Marvel universe. It is an abstract concept given conscious form. It is the supreme existence of Marvel. Even the five Cosmic Entities and all other metaphysical concepts and substances were meaningless before it.
To describe it, TOAA was like the fundamental principle, the great "Dao" of the Marvel Universe.
Looking at this being who was above everything in the Marvel universe, Lin Yu felt completely overwhelmed.
He was very surprised. He had not been in the Marvel universe for long. When he read those Marvel fanfictions, the protagonists at most met The Watchers or some gods. He had never seen a protagonist who had to have a talk with TOAA right from the start. He had not even started to cause much trouble yet, and this one had already appeared. What was going on?
But then he thought, almost all the protagonists who went to the Marvel universe started very weak. Even if they became stronger later, they were nothing to the entire Marvel universe. Most Marvel fanfiction protagonists, even by the end of their stories, were not strong enough to pose a major threat to Marvel. Even a one-punch-man level protagonist would not be a consideration for TOAA.
But he was different. With the power of his system, he could completely destroy the entire Marvel Infinite Universe in an instant if he just thought about it.
Perhaps TOAA also felt threatened, which was why Lin Yu met it so soon.
[ Threat detected ]
[ Initiating self-protection protocol ]
[ Initiating all infinite macro and micro universe observer states. ]
at the same moment TOAA appeared, the system's voice sounded in his mind. Simultaneously, the white runic sphere in his mind rotated, and one of the probability items instantly manifested with a 100% probability: (Infinite) Universe Observer.
[ Current state: (Infinite) Universe Observer. ]
"What?!" Lin Yu only felt that something within him had changed, but he could not quite tell what.
This was another form of dimensional ascension, an improvement in his level of existence. If the entire Marvel Infinity Universe was a painting, and TOAA was the strongest god within that painting, then Lin Yu, at this moment, had become the one who painted it.
No matter how exquisite a painting is, even if it is a painting of infinite dimensions containing infinite information, infinite universes, and infinite dimensions, everything within that painting, including the supreme gods of those infinite universes and dimensions, is meaningless to the painter.
Just as the editorial department of Marvel could obliterate the existence of TOAA in the comics at will, the TOAA in front of him was no longer a threat to Lin Yu.
The "(Infinite) Universe Observer" was not an ability, but a state of being, and it came with only one power: to observe the universe.
If Lin Yu thought about it, a single thought could create countless infinite universes with countless timelines, infinite parallel universes, and infinite dimensions. With a single thought, he could observe universes countless times more vast than the Marvel infinite universe, and "define" existences countless times far more stronger than TOAA.
Whether it was the Way of Heaven, the Great Dao, a God of Creation, or TOAA itself, everything could be "defined" and observed by Lin Yu with a single thought.
Observe everything, define everything, create everything, and at the same time, erase everything.
Now, Lin Yu was the creator of all information in the infinite universe!
It was as absurd as ever. The power of the system, the power of probability control, was indescribably strong. It made Lin Yu feel a deep sense of unreality every time, just like now.
Because Lin Yu had encountered a being that his current power could not handle, the system, following its instinct for self-preservation, had directly elevated Lin Yu to a level higher than TOAA to ensure the absolute safety of both itself and Lin Yu.
Just as Lin Yu had occasionally seen when checking the system interface, the probability of any item that posed a threat to him or the system was always 0%. Due to the instinct for self-preservation, the system, which was like his second personality, would never allow him to be in any danger.
"Cosmic observer?!" TOAA seemed to sense something and looked at Lin Yu, falling into silence.
Being absolutely rational, it would not have any emotional fluctuations. Even knowing that Lin Yu could erase its existence and the entire Marvel universe at any moment, it felt nothing.
"I can no longer pose any threat to you," TOAA stated. "But I still must ask you to leave here. Your existence has filled my universe with countless unpredictable changes in its trajectory. Your existence even threatens the stability of my universe. My universe is in peril and in danger of destruction."
"The danger of destruction? Why?" Lin Yu activated his "Overclocked Thinking" state, pondering YOAA's words.
"Because of your strength and your uncertainty," TOAA answered simply.
In truth, TOAA had one more thing to say. If Lin Yu were to fight with another being of his level, and the Marvel infinite universe happened to become their battlefield, then it would truly be doomed. Although the possibility was small, according to the principles of quantum uncertainty, such an event could happen in the next Planck instant!
This was why TOAA was so eager for Lin Yu to leave.
"Well, since you put it that way, I will leave," Lin Yu said, seeming to understand what TOAA had left unspoken. He could only reply helplessly.
After all, Lin Yu was not the type to arrogantly defy the heavens. He understood the reason TOAA wanted him to leave. He was relatively humble about such matters. Furthermore, his purpose in coming here, to learn the production technology of Iron Man's armor, had been achieved. So, it was fine to leave.
"However, please allow me to say goodbye to some of my friends," Lin Yu added.
TOAA nodded, its figure gradually fading until it disappeared.
"Mr. Stan Lee, I will come to chat with you when I have the chance," Lin Yu said, waving to the smiling old man. Then, he too vanished from the spot.
After Lin Yu and TOAA left, only Stan Lee remained. The strong wind whipped the snow against his clothes, making them flap loudly.
"I hope I have the chance to chat with you, interesting young man," Stan Lee said, shaking his head. Then he, too, disappeared.
Lin Yu appeared in the basement of the villa. He watched Tony, who was dismantling the AK-3 armor on a workbench. "Tony, I am leaving this world. Right now."
"Leaving? Why?" Tony, startled, put down his tools. After spending over half a month together developing the AK armor series, he and Lin Yu had formed a deep friendship. Tony truly felt Lin Yu was a good man.
"For certain reasons, I have to leave immediately," Lin Yu said. "You can keep that bracelet as a memento. If you want to take it off, you can. You can research the energy shield technology from it and add it to your armor." Lin Yu smiled at Tony and waved goodbye.
"Then..." Tony put down his tools and walked up to Lin Yu. He seemed a little reluctant. He was about to say goodbye when he remembered something. "Wait a moment."
He walked to his workbench, pulled out a USB drive, and plugged it into an interface. "Jarvis, make a copy of all the AK armor data and the AKR Arc Reactor schematics."
"Right away, sir," Jarvis replied. The data for Iron Man's armor was quickly copied to the drive.
"Here," Tony said, pulling out the drive and handing it to Lin Yu. "Your contributions are in there too."
"Thank you," Lin Yu said sincerely, taking the drive. "I will remember you." In truth, he had already learned all the production techniques for the AK armor and the AKR Arc Reactor. Even without these files, it would not be hard for him to make them back home. But he appreciated the gesture.
"Also, I almost forgot. Before I leave, I will give you a gift too." Lin Yu snapped his fingers at Tony.
A white light flashed over Tony's body. The AKR2 Arc Reactor embedded in his chest, along with the life-threatening shrapnel inside, fell out through the hole in his chest. Then, the hole itself quickly closed up. In moments, Tony's chest was restored to its healthy, original state.
In fact, Lin Yu had not only healed Tony's chest and removed the shrapnel. He had also endowed him with a self-healing ability comparable to Wolverine's, and it was heritable.
While he did not know how events would unfold in this world later, or if Tony would still need to snap his fingers, there was certainly no harm in giving Tony such a powerful regenerative ability.
"Goodbye, Tony, my friend," Lin Yu said with a final smile, before disappearing.
"Goodbye, Lin Yu, my friend," Tony whispered, touching his perfectly healed chest and staring at the empty space where Lin Yu had stood.

Deadpool was walking home with Vanessa, having just left the Xavier Institute. A light flashed, and Lin Yu suddenly appeared before them.
"Lin Yu?" Deadpool's eyes held an unreadable glint, though his tone was as casual as ever. "What, lost your way?"
"Wade, I am leaving now," Lin Yu said seriously.
"Leaving? OAA threatened you, didn't he? I knew it," Deadpool said, his words still flippant. "I have seen many guys who traveled here before. They stayed in Marvel for a long time, but many of those travelers were wiped out by OAA, or OAA just restarted the messy universes and timelines they changed, erasing their existence. You are an exception. It actually just asked you to leave."
"Because I am special," Lin Yu said vaguely. Then he continued, "Never mind that. I will give you a gift before I go."
Lin Yu snapped his fingers at Deadpool. A multicolored light flashed over Deadpool's body.
"Oh! This familiar feeling!" Deadpool felt the change instantly. He extended an Adamantium alloy blade from his wrist, then vanished and teleported behind Vanessa, making her jump. Then he looked up at the sky, and two red optic beams shot into the air.
"Bam! These are my old, weakened abilities! Thank you, Lin Yu!" Deadpool deactivated his Cyclops-like power, and the beams vanished. He turned to Lin Yu, excited.
"Just be happy. Goodbye, Deadpool. No, goodbye, Wade, my friend." Lin Yu smiled warmly, waved his hand, and his figure gradually faded until he disappeared from that spot, from the entire Marvel universe.
"Goodbye, Lin Yu, my friend," Deadpool said, a rare look of genuine reluctance on his face as he stared at the empty space where Lin Yu had vanished. He stood there, dazed for a long moment.
