After making sure that Rogers meant something, Tony was silent for a moment. If Killian really has the country in the East behind them, they really have to be cautious.

"So...... You should have sent someone to contact them, right?" said Tony, who continued to ask.

"Well, I sent a team over to continue the investigation. However, there is no news yet, and it may still be in contact. Nodding, Rogers replied in a deep tone.

"That's ......"

Thundered!

Just as Tony was about to say something more, a loud roar suddenly sounded above them, mixed with the thunderclap of thunder. Tony and Rogers' faces changed when they heard this, and then they quickly rushed to the open-air platform outside the living room.

Thundered!

Brush!

Just as Tony and Rogers rushed out, a cloud of thunder wrapped around a black object and quickly smashed from high in the air towards a place in New York. At the speed of this black shadow, even Tony can't stop him from activating the steel suit now.

Drip, drip!

As the shadow flew over Tony and Rogers' heads, a communicator beep suddenly sounded from Rogers' waist.

Brush!

Just as Rogers glanced at the news on the communicator, the black shadow had fallen directly to a place in the city of New York with a thunderous force. Rogers didn't have much surprise after seeing where the shadow fell, but Tony's eyes flickered a few times, as if he had thought of something.

"There, it should be Thor's apartment, could it be that the extremely fast black shadow just now was headed for him?"

Although Tony also made a move to intercept the meteorite-like black shadow just now, the speed of that black shadow was too fast, and without preparing in advance, even if the steel battle intent was dispatched, it couldn't be stopped. Moreover, Rogers' expression clearly knew the origin of the dark shadow.

"Well, it's for Thor. Because, that black shadow should have belonged to Thor. Hearing Tony's words, Rogers replied without concealment.

"It was supposed to belong to Thor......" Tony repeated meaningfully after hearing Rogers' answer.

"Then shall we go over and have a look? Look at the speed of the black shadow in the lyrics, if you smash it like this, you may directly smash a big hole in the ground. Tony then continued.

"No, since that thing has already come over on its own, then let Thor solve it. Hearing Tony's words, Rogers shook his head and replied.

However, Rogers was also helpless when he thought of the excitement of the researcher in New Mexico mentioned on the communicator. They were already studying other people's things, don't take your own things back now, they can't force them to come back and continue to study, Rogers doesn't have such a big face.

Moreover, during the Dark Elf invasion a few days ago, Rogers had also learned about Asgard's strength, as well as Thor's position of strength. So, if Thor takes the hammer back, then Rogers will treat it as if it didn't happen.

As for those researchers, let's transfer back to the S.H.I.E.L.D. headquarters, there are still a lot of things there for them to work hard.

"Really?" Hearing Rogers' reply, Tony was noncommittal.

Since Rogers didn't intend to explain in detail now, Tony wouldn't continue to inquire, anyway, he knew that the dark shadow was going towards Thor, and sooner or later he would find out what the situation was.

"Well, now that you're saying that the dark elves have retreated to their own territory, and that Asgard is keeping an eye on them, we can finally feel more at ease. Without dwelling too much on the shadow, Rogers said.

"Well, without the magic of aether particles, the dark elves can't jump. Nodding, Tony agreed with Rogers.

"Tony, have you thought of it before. The Earth we live on has come into contact with extraterrestrial civilizations so quickly, and it has been directly invaded by the other side. Standing on the top floor of the Stark Industries Building and looking at the bustling scene of New York, Rogers asked in a deep tone.

"To be honest, I didn't expect this day to come so soon. Hearing Rogers' serious question, Tony also answered seriously.

Hearing Tony's answer, Rogers raised his eyebrows, "Well, you mean, did you expect the Earth to be invaded by extraterrestrial civilizations?"

From Tony's answer, Rogers clearly sensed that Tony and himself had different psychological expectations about the invasion of Earth by extraterrestrial civilizations. Tony, it seems, is a little more calm.

"Steve, do you remember what the purpose of the alliance we formed at that time was?" Tony asked with a smile as Rogers looked a little surprised.

"Isn't the purpose of our alliance to form a real Earth Federation? Integrate the forces of the entire earth together, so that we can develop earth technology faster, and the progress of earth civilization will be much faster. Hearing Tony's rhetorical question, Rogers quickly gave his own answer.

"That's right, but the most important thing after the establishment of the true Earth Federation will be to enter the age of interstellar navigation. Entering the Age of Discovery, we will inevitably come into contact with other civilizations in the universe. And before we take that step, it is normal for other cosmic civilizations to discover us in advance and launch an invasion. After Rogers answered, Tony continued to add.

As a genius scientist, Tony is clearly more aware of what the future of this civilization will bring. However, the most critical thing is that Lin Rui once told Tony about the situations that the earth may encounter in the future, including the invasion of extraterrestrial civilizations.

"So, did you anticipate the invasion of the Dark Elves this time?" Rogers continued to ask with a twinkle in his eyes as he heard Tony's words.

As if sensing something was wrong with the atmosphere on Rogers beside him, Tony shook his head slightly.

"If I had really expected the invasion of the Dark Elves, this battle might not have been so awkward. However, since the spatial portal to the Dark Elves territory appeared from the Siberian side, I already had some guesses. It's just that the collision of the two civilizations that I guess is in Siberia, centered on that space portal, not in London, not the other party breaking into the earth in such an arrogant way. ”

"Moreover, I am a genius scientist, not a prophet. In the face of Rogers' questioning, Tony replied in a calm tone.

Hearing Tony's explanation and answer, the momentum on Rogers' body quickly retracted. Obviously, he also felt that he had just overthought it.

"The spatial portal on the Siberian side is still very stable, there are no dark elves coming from the other side, and we haven't sent any more teams over. Since Tony mentioned the spatial portal on the Siberian side, Rogers briefly mentioned it.

"Well, it's the best. Now neither we nor the dark elves can withstand too much tossing, and when our strength becomes stronger, maybe that will be the starting point of our counterattack. Hearing Rogers' words, Tony's eyes slowly became sharp.

As Tony said earlier, as the Earth continues to develop, their future is no longer limited to Earth. Therefore, their future will be truly in contact with other civilizations in the universe.

"Counteroffensive...... I hope that day won't come too late. ”

"Rest assured, it's not too late. ”

The sun was setting on the horizon, and the rays of the setting sun stretched the figures of the two big men on the top floor of the Stark Industrial Building long, but their postures stood straight in the breeze.
