"Parallel universe..."
Fury's face was calm, but a storm raged within his heart.
The parallel universe theory was a theory scientists had proposed long ago—that people faced countless choices in their lives, and each choice would cause a butterfly effect leading to different futures.
But people could only make one choice, so there was only one future.
But some scientists believed this wasn't the case—that time split when people made choices, and all choices were made simultaneously... Then, because there were countless things in the world, opportunities for choice were also endless, so there were countless universes that weren't entirely identical.
But this was just conjecture. Whether parallel universes existed or not, humanity's current technology couldn't confirm it.
And now, Tsuna claimed he came from a parallel universe. How could Fury stay calm?
He couldn't confirm the truth of what was said, but according to the fact that so many people from the Vongola Family had appeared in Harlem out of thin air, and they couldn't find any traces of their past existence... At least they hadn't existed on this Earth before.
And once the authenticity of parallel universes could be confirmed, and it could be confirmed that the Vongola Family really came from a parallel universe, then the enemies Earth needed to guard against weren't only aliens from space, but also visitors from parallel worlds.
After all, even if the Vongola Family really came from a parallel world, they were still "normal" people from Earth. If something like Resident Evil appeared, that wouldn't be funny at all.
Wait, parallel universes...
Fury suddenly thought of Quinn and those suspected demons who also had no discoverable past.
Especially Quinn—he'd suddenly appeared on a commercial street in Manhattan, and many passersby had witnessed this scene.
Were they the same?
Thinking this, Fury asked, "Mr. Sawada, do you know a man named 'Quinn'?"
"Quinn?"
Tsuna looked puzzled, then thought about it for a while and shook his head gently. "Sorry, I have no recollection."
Having said that, he turned to look at Chrome and the others and asked, "How about you?"
Chrome shook her head gently. "Judging by the name, it seems Western, but the only Westerners I know are within the family."
"Me too."
"Same here."
"Same."
"I also know the owner of the dumpling restaurant!"
Seeing this, Tsuna turned back and shook his head lightly at Fury, expressing that he didn't know him.
Fury stared intently at his eyes, but the other party's eyes were always as calm as still water, without a trace of ripples—nothing could be seen at all.
He wasn't surprised and continued asking, "What about demons? They're the kind of creatures that eat people, have immortality, and possess powers surpassing ordinary humans. Do you have such creatures as demons in your world?"
"There are myths and legends in my homeland, but I've never heard of them in reality."
Speaking of this, Tsuna's expression changed and he asked, "Mr. Fury asked this—are there such creatures as demons in this world?"
"There weren't before, but now there are more than a dozen people suspected to be demons."
"Does Mr. Fury also suspect they came from a parallel universe?"
"I used to think it was a biological experiment by an evil organization, but after listening to your words, Mr. Sawada, I came to this idea."
"I see. But there's no such thing as demons in our world—at least we haven't encountered any."
"Understood."
Fury nodded somewhat dully.
He hadn't gotten a satisfactory answer, which left him feeling frustrated, but he didn't forget his purpose for coming here. He refocused his eyes on Tsuna. "I've fully understood your origins. Although these cannot be proven, that's not what matters. What matters is the power you possess..."
Speaking of this, Fury's eyes swept back and forth between Tsuna and several Guardians. After seeing they were all indifferent without overreacting, he continued, "You have power beyond the norm, and the general police and army cannot handle you. Once you..."
"We are the Mafia, there's no doubt about that!"
Tsuna interrupted Fury's words and looked at him firmly. "But we're also human beings and will abide by the rules of humanity's 'game.'"
It was the rules of the game, not the law.
It meant: don't try to bind them with laws, which were superficial things that managed ordinary people. They only played games within the rules... That is, the rules that applied to other gangsters in this world also applied to them.
Fury was a smart person—he immediately understood what Tsuna meant and nodded in response. "That's natural, but you wanting to unify the gangs in the United States—this kind of thing isn't allowed."
Hearing this, Tsuna smiled lightly.
"Mr. Fury."
"Yes?"
"Have you ever heard this saying?"
"Go ahead."
"Failed leaders govern others, while qualified leaders are sought out to lead and guide others."
Hearing this, Fury was silent.
After a while, he said, "If you can achieve this level, then even becoming the president of the United States wouldn't be a problem."
"I'm not interested in running for president. I'm a mafia boss."
Tsuna smiled so innocently that Fury couldn't tell what he was thinking.
After a moment of silence, Fury stood up. "I'll greet all relevant departments in the United States shortly. As long as you don't commit serious crimes, no one will come to cause trouble. Your legal identity documents will also be sent to you later."
"Then I'll thank Director Fury."
Tsuna shook hands with Fury and personally escorted him out.
But as soon as they arrived at the gate, they saw smoke billowing in the distance—a large number of military vehicles and armored vehicles carrying heavily armed soldiers approaching quickly, with several helicopters circling in the sky.
"What does this mean?"
Hayato Gokudera rushed over and grabbed Fury by the collar.
Barton wanted to step forward to stop him, but was blocked by Takeshi Yamamoto.
He still had that big-brother-like smile on his face, but there was a cold light in the depths of those clear eyes.
(This guy is a killer!)
Barton had been an assassin before and was very sensitive to the aura of his kind. Just by looking at Takeshi Yamamoto, he felt the killing intent that locked onto him and simultaneously recognized his essence.
But that's why he was surprised.
Because before, he hadn't noticed it at all.
This showed the opponent was very good at disguising and was a top-tier assassin.
Barton glanced at the other Guardians but didn't act rashly.
"That wasn't arranged by me."
Despite being grabbed by the collar, Fury remained calm. He explained, "If I'm going to oppose you, why wouldn't I let them attack after I leave? Wouldn't that put myself in danger?"
Hearing this, Gokudera also realized his mistake and immediately released his hands and apologized to Fury. "Sorry!"
"It's fine."
Fury waved his hand to show he didn't care.
While straightening his collar, he said, "Don't be impulsive. Perhaps there's a problem in the chain of communication. I'll inquire."
