Inside the elevator.

"Did you see the way that security guard looked at you?" Natasha pressed the button on the top floor.

Neil didn't speak.

Natasha took Efez in her arms and sneered, "You're really good enough, the invitation is gone, won't you make a call?" We'll be sure to wait for you downstairs in advance, so you won't be stopped by security. ”

Neil glanced at Natasha with disgust, and said lightly: "Forget it, I don't want to just get to the door of the Stark Building and break through a layer of encirclement." ”

Hearing this, the corners of Natasha's mouth lifted, one hand held her elbow, folded her hands in front of her chest, and looked at Neil quietly.

"Were you envious just now?"

"What?"

"Envy that treatment, superhero treatment."

Natasha paused suddenly, and looked at Neil's deep and mysterious pupils seriously: "I just noticed your expression, and after hearing the taxi driver say that you don't have to pay, your eyes suddenly contracted, which means that you have been hit and feel unbalanced in your heart." ”

"Then your pupils begin to fluctuate, proving that you are in a very volatile mood, and after a moment of hesitation, your face finally shows a look of yearning."

Neil glanced at Natasha in surprise, shook his head and smiled, "Are you proving to me how good you are?" Okay, I'll admit that your agents are really good, but they don't always have to be right. ”

Natasha tilted her head and looked at him with a frown: "No, I think I guessed correctly, you told me this morning that you don't want to be a hero because it's too tiring to be a hero, but in fact you just weren't ready, you didn't consider our request well, you have feelings for humans." ”

"Admit it, Neil, you have a sense of justice in your heart."

Neil's fingers clenched around his arms and stood facing Natasha with a serious expression.

Natasha turned around slowly, looking straight into Neil's eyes.

Eye-to-eye is a means of observing the other party's emotions and psychology, and through looking at each other, they can often communicate with each other without words.

This is a unique way of communication that belongs to smart people, and it is also a psychological game.

It's as if you keep staring at a person's shoes and make him feel very uncomfortable, a person's eyes can show no less things and content than words.

The two looked at each other for a while, staring, frowning and blinking, and the atmosphere in the elevator was a little frozen for a while because of the silence of the two.

If there are other people staying next to you, you will definitely feel itchy all over, all kinds of goosebumps, scalp numbness, and I dare not take a breath more.

Taking a deep breath, Neil pondered for two seconds and said slowly, "You're right, I do have a crush on humans. ”

Natasha raised an eyebrow, a smile in the corner of her eye.

"But you think highly of me, and my character is not as great as yours! The reason I have a crush on humans is because I don't want to see monsters slaughter my fellow human beings, and the rest is simply because I'm human. ”

"I don't remember how many times I've said this, but you've never taken it seriously and thought I was an alien."

Natasha blinked her eyes: "Because you didn't take any strengthening serum, and you didn't have your skin turned green and slumped into a giant more than three meters tall, you can show such great strength." ”

"So you've always thought I'm an alien?"

Natasha thought for a moment and said, "You still have so many strange and at the same time very advanced technologies and weapons, which are not like the technology system that Earth has. ”

Neil licked his lips, he was craving to drink now, and his mouth was a little dry.

"Do you know about parallel universes?"

Natasha frowned and shook her head: "I haven't heard of it." ”

"I came across this astronomical term the other day when I was studying earth knowledge and culture and looking for a way home."

Seeing that Neil was about to start preaching, Ephes on the side hurriedly beeped, and then thoughtfully projected a large piece of image data and reflected it on the metal around the elevator.

It didn't have that before!

It wasn't until a few days ago that Neil had eaten some of the earth's technology, and suddenly had a whim, thinking of combining the technology of the earth with the celestial demon realm, and upgraded Efis again, so that it learned a lot of new abilities.

This upgrade not only gives this little cutie a lot of auxiliary functions, but also makes it slightly more combative, and even a layer of vibranium armor can emerge from the body when necessary, which is unbreakable.

Neil smiled and touched Efez's head.

His hearing was amazing, and movement within a hundred meters of his surroundings could not escape his ears.

So he knew that the miniature communicator behind Natasha's ear was functioning normally, and that the other end of the communicator was S.H.I.E.L.D., so his explanation was not just for Natasha alone, but for S.H.I.E.L.D. agents and Maria Hill on the other end of the communication.

"A parallel universe refers to a theoretically infinite or finite collection of possible universes, and I won't say much about the specific proper nouns, and you won't understand it if you talk too much."

Feeling that she was being underestimated, Natasha's expression was a little unhappy.

You scientists have good brains and look down on normal people, don't you? It's amazing to be able to make things and do science!

Ignoring Natasha's eyes, Neil pointed to a line of information on the holographic projection: "The general meaning of parallel universes refers to the fact that in the vast galaxy, there may be countless universes and spaces, and in these different cosmic spaces, there may be differences and gaps between time and things. ”

"And because the number of parallel universes is almost infinite, so in the huge number of parallel universes, there may be a parallel universe that also has the earth, and the earth also has the Avengers."

Although Natasha was trying to think and try her best to understand everything Neil was saying.

But after all, this is a new proper noun, and all the content belongs to her brain a new thing that she has never touched or understood.

And touching a completely new thing is not so easy to digest.

Seeing that Natasha's face was still full of contemplation and doubt, Neil shook his head, sighed, pondered for a moment, and spoke.

"For example, I blew up the invitation in this universe today, maybe in countless universes, there is another parallel universe like the earth, on that earth, everything is exactly the same as us, the only difference is Neil in another universe, his invitation did not ......blow up"

Hearing Neil mention the invitation again, Natasha unconsciously smiled again.

A black line appeared on Neil's head, and like a teacher in a lecture hall, he patted the message on the projection as if he were slapping the blackboard.

"Infinite quantities determine infinite possibilities, and this is the concept of parallel universes."
