American comics: A salted fish becomes a saint by hanging up

He must find Lin Yuan, even if he has to search the whole world and face endless dangers. However, in this journey to find his brother, he finds that he is not only racing against time, but also fighting against a conspiracy - a huge conspiracy about superpowers and the fate of the world.

Lin Nan has shown extraordinary talents since he was a child. His intelligence and physical fitness are far superior to ordinary people. His younger brother Lin Yuan is his only family, and the two depend on each other for survival. However, Lin Yuan's disappearance completely destroyed Lin Nan's life. He tracked down countless clues, from the underground black market in New York to the high-rise buildings in Los Angeles, from the desert in Mexico to the ice and snow in Canada, and all the clues pointed to one place - the Avengers headquarters.

After a difficult infiltration, Lin Nan finally stood in front of the Avengers Building. Looking at this towering building, his heart was filled with mixed emotions. As an ordinary person, he never thought that he would stand here one day. However, deep in his heart, he knew that this might be his last hope.

Lin Nan went deep into the Avengers Building, using his wisdom and stealth skills to avoid the heavy guards. He had to find clues and any possible evidence to prove that his brother had appeared here.

However, when he sneaked into a secret laboratory, a cold voice sounded behind him. "What are you looking for?"

Lin Nan turned around abruptly and saw a figure he couldn't ignore - Iron Man Tony Stark. Stark's eyes were sharp and alert, and his armor was glowing slightly, as if he was ready to attack at any time.

"I'm looking for my brother, Lin Yuan," Lin Nan looked straight at Tony without flinching. "He disappeared three months ago, and my clues lead me here."

Tony frowned, obviously not impressed by the name. "There is no such thing as Lin Yuan as you said," he replied, with a hint of impatience in his voice. "This is the territory of the Avengers, not a reception center for missing persons."

"I know you are hiding something," Lin Nan's voice became more determined, "I just want to find my brother. If he is really not here, I will leave."

Tony was silent for a while, then turned and walked to a terminal, seemingly typing something. Lin Nan stood there, nervously watching his movements. He knew that the man in front of him held countless secrets, and might also hold the fate of his brother.

"I checked," Tony finally said, "There's no record of your brother here. But..." His voice paused slightly, "Some things are definitely a little strange. We've recently discovered some unusual activities that may be related to your brother's disappearance."

"What is it?" Lin Nan asked anxiously.

"The energy fluctuations of the Cosmic Cube," Tony looked at the data on the screen with a frown. "We have kept this thing well, but it has recently started to move. This fluctuation may affect some unknown areas, or even humanity itself."

Lin Nan felt a chill running down his spine. The Cosmic Cube was a powerful energy source that could destroy the world. If something went wrong with it, the consequences would be disastrous.

"Your brother may have been caught up in this storm," Tony continued, his voice becoming more serious. "But we're not sure exactly where he is yet. This isn't something you can handle alone."

"I don't care," Lin Nan answered without hesitation, "As long as I can find him, I'm willing to take any risk."

Tony stared at Lin Nan, his eyes revealing a hint of mixed emotions. "I can understand your determination," he said, "but you need to understand that this matter is much more complicated than you think. You may be facing an enemy from the entire universe."

Lin Nan was silent for a moment, then nodded firmly. "I have never been afraid of any enemy," he said calmly, "I just want my brother to come home."

Tony took a deep breath, as if he was making a difficult decision. "Okay," he finally said, "let's go find him together."

With this decision, Lin Nan officially joined the ranks of the Avengers. Although he is not a superpower, his courage, wisdom and determination make him stand out in this team. With the help of Tony, he gradually learns the secret of the Cosmic Cube and the huge threat that may be hidden behind it.

However, just when they made some progress, Lin Nan suddenly received a mysterious message. This message came from an unknown source, and the content was brief but shocking: "If you want to see your brother, come to the Shadow Land."

Shadow Land, this name surprised Tony. It is a place that few people know about, full of unknown dangers and mysterious powers.

"No matter what it is, I'm going to go," Lin Nan said without hesitation.

Tony looked at Lin Nan, knowing that he could not stop his determination. Finally, he nodded, provided Lin Nan with some necessary equipment and information, and asked Black Widow Natasha to go with him.

The two set out for the Shadow Land, where there was a gloomy atmosphere and the surrounding environment seemed to be changing all the time, as if they had entered a different dimension from reality. As they went deeper, they encountered more and more unknown creatures and various strange traps.

At this moment, Lin Nan and Natasha were surrounded by a group of mysterious enemies. These enemies were wearing black armor and seemed to have the ability to manipulate shadows. Their leader was a tall mysterious man who exuded a powerful pressure.

"You are Lin Nan," the leader said with a sneer, "your brother is already one of ours."

"What did you do to him?" Lin Nan roared, his eyes full of hatred.

"He chose his own fate," the leader replied coldly, "and now you must pay the price for your choice."

The battle was about to start, and Lin Nan and Natasha tried their best to resist these dark forces. However, their numbers and strength were far inferior to those of the other side, and they were eventually trapped in a dead end with no way out.

Just when they were about to despair, the sky suddenly split open, and a dazzling light pierced through the darkness. A powerful energy descended from the sky, repelling the dark forces. Then, Lin Nan saw a familiar face - it was his long-lost brother, Lin Yuan.

But Lin Yuan's eyes were no longer as warm as he remembered, but full of indifference and alienation. A faint energy shield surrounded him, as if announcing his new identity.

"Lin Yuan?" Lin Nan called his brother's name tentatively, his heart filled with conflicting emotions.

"Brother," Lin Yuan's voice was cold and ruthless, "You shouldn't have come here."
