At this moment, Ivan Vanko wailed in pain, staggered against the pillar, holding his broken arm.

Ye Zixun came to his senses instantly, took out the tranquilizer gun from his waist, and aimed accurately at Ivan Vanko's neck.

“Puff——”

The bullet with a special anesthetic hit Ivan Vanko's neck.

Ivan Vanko's body stiffened, then his left arm dropped limply and he fell to the ground.

Ye Zixun took out a black certificate from his arms, held it high, walked into the venue, and shouted loudly.

"FBI!"

Hearing the familiar voice, Natasha breathed a sigh of relief, quietly put the pistol back into her bag, and stood up pretending to be scared.

Ye Zixun first checked Ivan Vanko's condition and saw that blood was still flowing from his broken arm, so he took out a hemostatic agent and injected it into his broken arm, temporarily saving his life.

Then, Ye Zixun stepped over Ivan Vanko's body, came to Tony, and said with a serious expression: "Mr. Stark, we have reason to suspect that this terrorist in simple armor is coming for you. I suggest that you accept our protection..."

"Accept your protection?"

Tony glanced at him, then stepped right in the middle of the red suitcase.

In an instant, the red-painted Mark V Iron Man suit quickly unfolded, and the flowing red metal covered the entire body at an extremely fast speed, completely wrapping up Tony Stark's body.

In just a few seconds, Tony Stark turned into Iron Man in silver-red armor.

Tony turned his head and glanced at Ye Zixun indifferently with his visor shining with white light.

"I can protect myself..."

After saying that, Tony walked towards the unconscious Ivan Vanko, took off the energy source that was lit on his chest, and silently looked at the simple Ark reactor in his hand, wondering what he was thinking.

Natasha comforted the frightened Pepper, then came to Ye Zixun and whispered, "You are late."

Ye Zixun looked at the blood-stained floor and the three bodies lying in a pool of blood, and nodded silently.

Natasha also sighed quietly and blamed herself: "I should have taken action."

Ye Zixun shook his head and said, "It's not your fault. You have your own mission and you can't expose yourself until the critical moment. If you want to blame someone, it's my fault for being too arrogant and trusting my own judgment too much. This is why several people died at the hands of Ivan Vanko."

At this point, Ye Zixun paused and asked in a low voice: "But what was that golden lightning just now?"

Natasha shook her head. "I don't know either, but I suspect it may be related to the target of my investigation."

…

…

Kamar-Taj, library.

Lin Zhongtian's hand, which was flipping through the pages of a book, paused slightly, and then he closed the thick ancient book in front of him thoughtfully.

There was a trace of his remaining consciousness on the gray fog coin engraved with the Seal of the Void. It was this trace of consciousness that activated the gray fog, transformed it into golden lightning, and saved Tony Stark in time.

At the same time, Lin Zhongtian also saw everything that happened at the banquet through the gray fog.

Including Natasha who quietly took out a pistol, and the SHIELD agents who hurried over at the end.

Since the gray fog's vision was a high-dimensional white-eye perspective, Lin Zhongtian could clearly see the Hulk serum carried by Ye Zixun. The liquid stored in the needle-free syringe was filled with extremely rich vitality.

"What is that, could it be the Super Soldier Serum?"

Thinking of this, Lin Zhongtian suddenly became interested. He gently raised his right hand and, in front of the shocked gaze of the librarian, Master Wang, showed him how to use the Ring of No Suspension to open the golden spark portal.

Afterwards, Lin Zhongtian put the ancient book back to its original place through the portal, opened a new portal and walked into it.

On the other side, the unconscious Ivan Vanko had been arrested by the local police and after simple treatment he was locked in a cell awaiting interrogation.

Not long after, Tony Stark, dressed in plain clothes, came to the outside of the cell accompanied by Ye Zixun, and looked at the unconscious one-armed strong man in the cell through the iron bars.

"How long will it take for him to wake up?"

"I guess I'll have to lie down for a few hours..."

Ye Zixun shrugged and said, "Thanks to the logistics department, the things I used have a strong lasting effect. If you have anything to ask him, it's best to stay here for two more days until he recovers."

“…”

Tony twitched his lips, glanced at him, and suddenly said, "You are not the FBI!"

Ye Zixun thought about it and smiled, "I can be."

Tony looked thoughtful, as if he understood what he meant.

"Let me guess, is your boss that annoying black bald one-eyed guy?"

"...Huh?" Ye Zixun's eyes widened upon hearing this, and he quickly raised his hand and said, "Boss, you have to listen carefully, this is what Tony Stark said himself, it has nothing to do with me!"

"No need to explain. Although I am blind in one eye, my ears are fine."

A faint voice came from behind him. Tony raised his eyebrows and turned around.

I saw a bald man wearing a black windbreaker and a black eye mask walking towards me from behind.

It was Nick Fury, the director of SHIELD, who had once met Tony Stark.

"I told you I had no interest in your super secret boy band."

"Haha." Nick Fury laughed and shook his head, "Of course you are not interested. I remember you said that you want to do everything by yourself. What is the result now?"

"..." Tony fell silent.

Nick Fury said calmly, "Four days ago, you confidently announced at the hearing that no one would be able to copy your Iron Armor and Ark Reactor in the next 20 years. But in just four days, a tattooed man wearing a simple Iron Armor and the same Ark Reactor as yours appeared in front of you and killed three people in front of you."

"who is he?"

Tony suddenly asked.

Nick Fury turned to look at Ye Zixun, who very tactfully introduced Ivan Vanko's identity on behalf of his boss.

After listening to Ye Zixun's introduction, Tony frowned tightly.

"Since you already knew he would come for me, why didn't you warn me?"

"Remind you?" Nick Fury sneered, "Who do you think you are? Do you think you are Iron Man, a billionaire, and the whole world should revolve around you?"

"And who told you that we already knew Ivan Vanko's whereabouts?"

As he spoke, Nick Fury pointed to Ye Zixun beside him and said, "Rivers Skinner is a Level 7 agent of S.H.I.E.L.D., responsible for investigating the mysterious exoskeleton warrior incident that appeared in Russia. He is one of my best agents, but even for him, it took more than half a month to find out the identity of Ivan Vanko this morning."

"As for Ivan Vanko's whereabouts, that is Rivers's guess."

"He wasn't sure that the target would appear here. I allowed him to come alone because of his past experience and my trust in his ability. To be honest, I have more important things to do in the southwestern United States. If this matter hadn't involved you, I would never have wasted my best manpower in Morocco, let alone come here in person."

Hearing this, Tony couldn't help but turn his head and look at Ye Zixun.

Ye Zixun nodded, confirming that what Nick Fury said was true.

Tony frowned. "So what do you want to say?"

Nick Fury looked into Tony's eyes and said calmly, "I want to tell you that the world is still the same world. Nothing has changed because you became Iron Man. Even at this moment, there are still many evils growing in every corner of the world, and my people are fighting in these dark corners that you can't see."

"And you, the great Iron Man, the famous billionaire Tony Stark, even if you are unwilling to condescend to join us, please don't hold us back, and don't become a problem figure that we need to solve like you are now..."

"Problematic person?" Tony frowned. "What do you mean?"

"Literally."

Nick Fury said calmly, "Now, I have at least three things on my hands that are related to you. The first thing is your Iron Armor. The military is trying to force you to hand over the technology, or at least hand over a finished product, and I am trying to ease the relationship between you and the military."

"The second thing is this Ivan Vanko. Like you, he has mastered the technology of the micro-arc reactor. No one is sure whether he has sold this technology to ambitious forces on Earth. As for the third thing, it is the thing on your chest. How is it? Palladium metal poisoning should not feel good, right?"

"If you need it, I can give you some lithium dioxide, which can relieve your symptoms of palladium poisoning..."

Perhaps because he was a little distracted by Nick Fury's words, Tony subconsciously shook his head to refuse.

"No, I feel fine now."

"Oh?" Nick Fury's eyes sparkled. "Someone solved your palladium poisoning problem for you. Who was it? The one who gave you a white jade coin that can emit golden lightning? What's his name?"

"Forest……"

Tony Stark spoke subconsciously, then suddenly came to his senses and frowned tightly.

"Wait, are you trying to trick me?"

"How do you know this?"
