Chapter 146: A hint of caution in his tone

"This...what's going on?" Su Chen muttered to himself in surprise.

Suddenly, he heard a burst of hurried footsteps not far away, and when he looked up, it turned out to be Iron Man Tony Stark flying over fully armed. Su Chen couldn't believe his eyes, he tried to stand up, but his body seemed to have not fully recovered yet, and he could only barely lean on a piece of rubble.

"Hey, kid, are you okay?" Tony's voice came from the helmet, sounding a little vague.

Su Chen opened his mouth and finally uttered only one sentence: "I...why am I here?"

Tony didn't seem to have an answer to this question either. He shrugged and then held out his hand. "Let's leave here first. This place is not safe."

Su Chen grabbed Tony's hand and was lifted up by Tony easily. Then, Tony turned on the jet at his feet and took Su Chen to the top floor of a tall building not far away. It was relatively safe here, with a wide field of vision, and he could clearly see the battle scene on the street below.

"You don't look like a local," Tony looked at Su Chen's clothes, "How did you get here?"

Su Chen smiled bitterly, "To be honest, I don't know. I just remember that I was watching TV at home, and then... I came here."

Tony frowned, "That's really weird. We need to find Doctor Strange, maybe he can answer your questions."

After saying that, Tony activated the communication system, and soon after, a rotating portal appeared in front of them, and a man in a red cloak walked out of the portal - Doctor Strange, Stephen Strange.

"Tony, what's so urgent?" Strange asked, his eyes then fell on Su Chen.

"This gentleman, Su Chen, said that he appeared here inexplicably, as if he came from another world." Tony explained.

Strange approached Su Chen, his eyes full of inquiry. He raised his hand and cast a spell, and Su Chen immediately felt a strange energy flowing around his body.

"Indeed, he has an energy that does not belong to this world." Strange said, "It seems that he really comes from another universe."

Su Chen felt dizzy and the scene in front of him gradually became blurred. Countless images flashed in his mind, including memories of the past and some strange and weird scenes.

"I can feel the confusion in your heart," Strange soothed him, "You are now in a parallel universe in the multiverse, and your original world may only be a shadow of this place."

Su Chen tried hard to digest this information, his mind was filled with countless questions, but he knew that now was not the time to ask questions. He took a deep breath and tried to calm himself down, "So, how should I get back?"

Strange pondered for a moment, "This problem is not simple. It requires the help of powerful forces in the multiverse. But before that, we must figure out how you came here. Perhaps there is a bigger conspiracy behind this."

At this moment, a loud noise was heard in the distance and the entire roof was shaking. Su Chen turned around and saw a huge Hulk fighting a group of aliens. The battle scene was extremely fierce.

"It looks like we don't have much time," Tony sighed, "Su Chen, we need your help now. Since you've been involved in this battle, you have to do something."

Although Su Chen was full of doubts, he knew that he had to face the crisis first. He nodded, "What should I do?"

Tony patted his shoulder with a smile, "Very good, now follow me." After that, he took Su Chen and flew to the center of the battle.

During the battle, Su Chen saw Thor wielding his Mjolnir, Natasha the Black Widow nimbly moving between battlefields, and Captain America Steve Rogers directing the entire battle. They were all heroes that Su Chen had seen countless times in movies, but now they were standing in front of him in real life, fighting alongside him.

"Su Chen, catch it!" Tony shouted and threw him a strange device.

Su Chen hurriedly caught it, and Tony explained: "This is an energy shield that can withstand the attacks of aliens. You need to find the core of this battle - the leader who controls this group of aliens."

Su Chen nodded, put on his shield, took a deep breath, and rushed into the battlefield. Although he did not have super powers, he quickly found an alien commander with his agility and wisdom. It was a tall monster with a blue glow all over his body, holding a huge war hammer.

Su Chen knew that this was a tough opponent, but he did not back down. He used his shield to block several attacks from the opponent, and then waited for an opportunity to counterattack. Just as he was about to be suppressed, a bolt of lightning suddenly fell from the sky, and Thor fell from the sky, and Thor's hammer slammed into the enemy.

"Well done, friend." Thor smiled at Su Chen and then fought alongside him.

Su Chen felt an unprecedented power. He was no longer an ordinary office worker, but a hero fighting side by side with the Avengers. The battle was tight and intense, and every second was on the verge of life and death.

Finally, with the joint efforts of the Avengers, they repelled the alien attack, and only ruins and fallen enemies were left on the battlefield. Su Chen sat on the ground, his whole body aching, but he felt a sense of satisfaction he had never felt before.

"What do you think we can find here?" Long Guo asked in a low voice, looking around warily.

Su Chen stared ahead, his eyes flashing with determination and firmness, "I'm not sure, but I can feel that the energy fluctuations here are extremely strong. Maybe the time criminal is using this place to conduct some kind of experiment or prepare some kind of plan."

They walked forward along a narrow passage, feeling the ancient atmosphere contained in the ruins. Gradually, they came to a spacious hall, which was covered with ancient murals and mysterious runes. In the center of the hall, on a huge stone platform, there was an altar that was shining with a faint light.

"It seems that our target is there." Su Chen pointed at the altar, with a hint of vigilance in his tone.

Long Guo held the weapon tightly in his hand, his eyes fixed on the altar, vigilantly guarding against anything that might happen.

The two men walked slowly towards the altar. They felt a powerful energy fluctuation in the air around them, which made them feel uneasy.

Su Chen's mind moved, and he immediately decided to go and check it out. Perhaps there, he could find some useful clues or props to help him better face the upcoming challenges.
