American comics start with asking Iron Man a question.

Everyone can see clearly that Tony Stark wouldn't have made that choice if he hadn't paved the way for Peter Parker.

[Congratulations to Tony Stark for winning one NZT48 pill!]

[The reward has been issued, please check your account!]

With these words from the system, a small, seemingly inconspicuous transparent pill immediately appeared in Tony Stark's hand.

Without a doubt, it's NZT48.

"Holy crap, there's such a miraculous drug in the world."

Even Tony Stark was astonished after sorting through the information about NZT48 that had been implanted in his mind.

I was a little provoked.

The reason is simple: this NZT48 is just too overpowered.

However, after the initial surprise, Tony Stark's eyes couldn't help but light up. This god-like drug was practically tailor-made for him.

"This is NZT48?"

Thor leaned closer, glanced at the small pill in Tony Stark's hand, and looked very interested. "This looks quite ordinary, nothing special, but your expression tells me that this thing is not simple."

"This is a small pill? Mr. Stark, what is this pill for?" Peter Parker couldn't help but ask with great interest.

"This is a drug that can comprehensively improve brain efficiency. Just one pill can fully unlock the brain's potential and increase its utilization rate," Tony Stark explained simply to everyone.

“Wow, this pill is a good match for Stark,” Scott Lang said with a shrug.

"Stark, to what extent can this drug develop the brain? I think it must be amazing, right?" Strange asked with a hint of curiosity from his hospital bed.

“That’s right.” Tony Stark nodded.

"In another parallel universe, there is a down-on-his-luck writer named Eddie who is so poor that he can barely afford to eat or pay his rent."

"But by chance, he accidentally ingested an NZT48 pill, and guess what?"

"He can easily recall the books he casually flipped through more than a decade ago in order to pick up girls."

"He only needs to listen to other people talk for a few minutes to quickly master a language that is completely unfamiliar to him."

“A skill he has never encountered before, such as playing the piano, can be mastered in just three days from scratch.”

"When he was ganged up on by thugs, movie clips he had seen would automatically flash through his mind, making his body know how to fight back. He was self-taught and easily knocked all the thugs to the ground."

"Chemistry, finance, medicine... any knowledge is completely accessible to him, like knowledge cards that have fallen on the ground. All he has to do is bend down and pick them up."

"Everyone, now you know what kind of medicine NZT48 is, right?"

Tony Stark, with a hint of smugness on his face, introduced himself to everyone around him.

Holy crap!

Peter Parker was the first to exclaim in surprise, his mouth agape. "Mr. Stark, this medicine is amazing! It's practically a miracle drug!"

Not only Peter Parker, but everyone else was also amazed by NZT48.

They never imagined that this tiny pill could develop the human brain to such an extent.

If even a down-on-his-luck writer can reach such an unbelievable level, then what about Tony Stark, who is already much smarter than the average person?

It's unbelievable.

I'm afraid that Tony Stark, who swallowed NZT48, will really become a god in the future.

It seems that even the entire universe can't stop Tony Stark's steps.

In the future, this thing might break through the dimensional barrier like Infinite Ultron; it's entirely possible.

"But it's a pity..."

But then Tony Stark changed the subject, his voice tinged with regret, "The effects of NZT48 only last for one day."

This means that Tony Stark can only be "Brain Superman" for one day.

“As expected, this is the system’s style,” Strange said, unsurprisingly.

The system can indeed allow users to cheat, but under normal circumstances, the cheat is not allowed to be used too extensively; there are usually limitations on its use.

Even so, even if it's only for one day, this drug will still be of immense value in Tony Stark's hands.

"In addition, this drug has certain side effects, such as causing biological fatigue and addiction... However, if there is only one pill, these side effects can be ignored."

Tony Stark then added.

[Answer complete. Answer explanation to begin!]

At that moment, a system notification sounded, and a corresponding video appeared on the big screen.

The first thing that came into view was a tranquil and peaceful wooden cabin by the lake.

Tony Stark came out of the house, his hands in his pockets, and went straight to a small tent in the yard.

"Lunch is ready, Morgan H. Stark! Do you want lunch?" Tony Stark called out to the small tent from his small stool.

Morgan Stark?

Tony Stark, sitting in front of the screen, was slightly taken aback. Could this be his daughter?

Soon, a little girl wearing an Iron Man helmet emerged from the tent.

She pointed at Tony Stark and said, "Define what you're eating, or you're going to get wiped out."

“Okay, you shouldn’t wear that. It’s an anniversary gift for your mother,” Tony Stark said softly to the little girl. “Do you want to eat? I can give you a bunch of crickets wrapped in lettuce.”

"No."

"Didn't you want to eat that? And how did you find this?"

"In the garage."

"Really? You went looking for it on purpose?"

"No."

After playing with his daughter for a while, Tony Stark picked up Morgan Stark and headed back inside.

But at that moment, Tony Stark glanced around and noticed three more people standing in front of his house.

Captain America, Black Widow, and Scott Lang.

Clearly, after Scott Lang sought help from Captain America last time, Captain America and his companion took Scott Lang to Tony Stark.

Needless to say, Tony Stark then hosted some old friends, and Scott Lang and the others told Tony Stark about their idea of ​​time travel.

“We know how crazy this sounds.”

After expressing his thoughts, Scott Lang couldn't help but say this again.

"Tony, after all we've been through, is there really anything that's impossible?" Captain America chimed in.

"Quantum fluctuations reach the Planck scale, leading to Dirk's viewpoint."

Tony Stark spoke up, and his words were incredibly professional: "Can we agree on this? Simply put, you can't come back here."

“I’m back!” Scott Lang interjected.

“No, you just got lucky. It’s a one-in-a-billion chance in the universe.” Tony Stark waved his hand. “Now you want to proceed with… what was your name again?”

Time theft!

“That’s right, time theft. Why didn’t we think of that before? Because it’s too ridiculous, it’s just wishful thinking.”

"The Infinity Stones are all in the past. We can go back and get them. We can snap our fingers and bring everyone back."

"Or make things worse, right?"

……

It's clear that Captain America, Black Widow, and others had high hopes for Tony Stark, but unfortunately, despite their efforts to persuade him, they couldn't convince him.

In the end, the group returned empty-handed.

However, as everyone watching knows, this matter will not end with the departure of Captain America and his companions.

Whether it was the others returning later to persuade Tony Stark, Tony Stark changing his mind on his own, or some other possibility.

In conclusion, Tony Stark ultimately went against his original intentions and invented the time-space locator.

Ultimately, deep down, Tony Stark couldn't stand by and watch a way to save half the world's population without doing anything.

At this moment, the image on the screen changed.

Inside the kitchen, Tony Stark was washing dishes and tidying up.

When everything was almost tidied up, he unconsciously walked to a cabinet.

I casually took out one of the picture frames from the top.

The framed picture shows a photo of Tony Stark and Peter Parker together.

“Mr. Stark, is that me? That’s a picture of the two of us! This is amazing!” Peter Parker exclaimed excitedly as soon as he saw the picture frame.

She looked at Tony Stark with excitement and took the opportunity to say, "Mr. Stark, after this quiz, could we..."

"It depends on my mood, child."

Tony Stark had already agreed in his heart, but he still said it with great pride.

on the screen.

Tony Stark, however, stared at the photo frame in his hand with a complicated expression, lost in thought.

Clearly, he was deeply troubled by Peter Parker's death.

Finally, Tony Stark's expression hardened, and he made a decision.

“I have a little idea, and I want to see if it works, so I want to do one more simulation before I wrap up work tonight.”

"This time, we will reverse it in the form of a Möbius strip."

With Tony Stark's own account, we see him beginning to build the model.

"It's turning around!"

On Friday, he faithfully carried out Tony Stark's orders.

“Okay, let’s perform spectral decomposition on the eigenvalues ​​of that particle. That will take a little time.” Tony Stark was also performing some operations.
