"Can't go back to Asgard?" Tony repeated Thor's words in surprise, "Do you mean that it's like getting lost?" ”

Thor nodded gloomily.

Normally, the Asgardians use the "Rainbow Bridge" to quickly travel between the universes. From Tony's point of view, he has always felt that this is some kind of extremely advanced space jumping technology, which can use energy flow to carry people or things to achieve interstellar space shuttle. However, Thor has always referred to it as "magic", which he feels is fundamentally different from the technology on Earth.

The guardian of the Asgardri Rainbow Bridge is Heimdall, the gatekeeper of Asgard, loyal to Asgardian royalty and a personal friend of Thor. Heimdall is in charge of Excalibur, which acts as the key to the Rainbow Bridge, and anyone entering or leaving Asgard must ask for his permission. At the same time, he also has the eye of Heimdall, which can perceive all things, and his sharp gaze can penetrate space, see through the stars, and watch even the most hidden corners of the Nine Realms. So no matter where the Asgardian warrior calls Heimdall in the Nine Realms, he can always notice it in time and open the Rainbow Bridge to bring them back.

But now the system seems to be a little difficult to use.

"Heimdall didn't respond to my call." "Normally this doesn't happen. Heimdall's eyes saw everything, and he didn't respond with only one explanation, which was that something had happened to Asgard. God's Domain needs me now, and I must go back. ”

Tony took a small step back - only then could he naturally look up and look at Thor.

"So you mean," he asked, "you want me to help you find a way back?" ”

Thor nodded.

"Wow, that's a novelty. The last time we talked, you were quite disdainful of technology, why did you change your mind? ”

Thor's face was a little unsightly. He instinctively felt that something must have happened to Asgard now, and that he must be in great need of his help now. And the Avengers also know that Thor has always been repulsive to Earth technology - of course, this may have something to do with the threat of having to deal with the accident born from the lab in three days.

Tony patted him on the shoulder as he explained, "Okay, just kidding." I'm certainly happy to help. In fact, I happen to have something that might help. Come on, I'll show you. ”

Tony got up and walked towards the lab, and Thor followed.

The decorative sink against the inner wall of the hall sank to the bottom of the floor, and the interior wall was moved along a gap to the sides, revealing a secret door. Tony led Thor through the secret door to the lab hidden in the back. As they descended the circular escalator, Tony explained, "I converted the lab into this and reinforced it to the standards of a military fort. That way my lab won't be in trouble the next time there's a 'Hulk-class' problem. ”

Thor smiled and symbolically praised his design.

"I've been very interested in this technology since you first showed us the 'Rainbow Bridge' in Asgard - okay, I know you want to say it's magic, not technology. But you have to know that anything that exists in the world can always be explained by science, but sooner or later. ”

Tony stood still, pulled down a blue transparent operation interface with a wave of his hand, and reached out and tapped a few times in the interface.

"So I scanned and collected the energy of that 'rainbow bridge' and did a couple of tests. Then, by tracing the location of the Rainbow Bridge's energy, I found that Asgard seemed to have a connection to the Earth itself. ”

"The nine kingdoms are inherently interconnected." Thor interjects, "Tree of Life......"

"Well, I've heard of myths and stories, and I've read a lot." Tony interrupted his story with a wave of his hand, saying, "But I'm not talking about unfounded myths here, but the analysis of data that has actually been obtained shows that there is a connection between the Earth and Asgard." According to my speculation, the two worlds should be connected by some special situation, and exist in different dimensions. So it gave me an idea, a way to maybe cross the spatial barrier and enter the unknown. That's why ......"

He deliberately paused and clicked a button in the virtual interface. The floor tiles deformed and opened, and a complex black mechanism rose up and stood in front of the two of them.

“...... I built this. ”

Tony took two steps to the side, proudly displaying his work as if he were introducing a new product at a launch event.

However, this rugged guest was not so cooperative. Thor looked at the device with a puzzled expression, "This machine can break through the barriers between the nine kingdoms and help me return to Asgard?" ”

There seemed to be some doubt and uncertainty in his tone, which made Tony a little unhappy.

"Of course it does." "It's just that it also needs energy, strong enough energy — something I'm sure you can solve." Then it also needs to find a weak point. A part of the Earth and the Asgardian plane where the barrier is weakest. It can break through barriers and open a wormhole. You go in from here, and when you come out, you're at the gates of Asgard. ”

Thor glared, scrutinizing every line and screw of the swarthy machine, as if trying to see if it had the skills to do so.

"Alright, don't stare at it." Tony said with some amusement, "Be patient, I'll get a few satellites right now to scan for weak points in space." I promise you will be back to your palace in one day. ”

Thor nodded earnestly, "Thank you, Tony." I won't forget. ”

***

According to the design drawings left by Victor von Doom, Michael completed a new quantum shuttle in just two hours with the help of several construction robotic arms in the laboratory. After conducting a few basic tests, he was ready to go.

The aether particles in Jane Foster's body and the dark elves are interconnected. In the movie, the moment the Aether is activated, the Dark Elves who have been sleeping for 5,000 years are awakened, and the Dark Elves can also remotely locate the Aether.

Michael speculated that this approach should be reversible, and he was right. He uses the aether to locate the dark elves in turn, and uses the aether's energy to calibrate the course of the dimensional shuttle. He locked his bearings and activated the machine, and the high-intensity energy stirred up a pitch-black rift in the space, like a large mouth that opened hideously, and there was darkness at the other end.

Dark World.

"I still don't think it's a good idea, sir." Shirley exclaimed, "Maybe you should at least do a few more tests." ”

"It's enough to test, sometimes you have to learn to be brave."

Michael picked up the fainting female doctor and walked towards the dark rift.

"Help me guard the entrance, Shirley. If I don't come back after three days, you can destroy the spare circle. ”
