Outside the timeline.

The Mystery House of the Overseer's Headquarters.

In the research hall, Tony Stark and Reed Richards, who have returned from vacation, are putting the finishing touches on the dimensional travel device.

"Zhang Yu, this guy is really, I haven't had a good rest during this time, and I finally arranged such a troublesome task when I was free."

Tony Stark looked at the readings on the panel, his fingers tapping on the keyboard, and said to Reid Richards behind him without looking back.

"This is a dimensional crossing device, Zhang Yu asked us to make this thing must have an important role, in order to better ensure the safety of the wasteland universe, it is necessary for us to do these things." Reid Richards spoke.

Tony Stark couldn't help but pout. "I'm not like you, I just went back from vacation to spend time with my children, I've been in this house for I don't know how long, it feels like centuries have passed."

"If you're really bored, maybe you can visit the wasteland universe once in a while." Reid Richards made a suggestion.

"I can't go away, I can't make contact with people, I can only look at others from a distance, what's the point?"

Tony Stark waved his hand, but Reed Richards' words gave him a good inspiration, and after a pause, Tony continued.

"By the way, don't Carla and Pietro have a mission to go to other universes, I think I can try it, and I believe they will not refuse my help."

Hearing this, both Reed Richards and Susan stopped what they were doing.

The two looked at each other, and then looked in the direction of Tony Stark.

"Tony, it's dangerous to disarm the other multiverses without permission, and don't forget, it's our job to keep the wasteland safe from the enemies of those other universes."

"I know, but I'm not an enemy, and besides, that universe is safe." Tony Stark clasped his arms. "Don't think I haven't inquired, that little imp from Pietro has been to that universe."

"I still find it troublesome to get involved in that kind of thing, if you're really bored and want to get out and about, then I suggest you follow Zhang Yu to explore other lost dimensions hidden near the wasteland universe." Reed thought for a moment and said.

"Lost Dimension?" Tony Stark was stunned for a moment.

"Yes, Zhang Yu asked us to build a dimensional crossing device, isn't it, the role of this thing is to shuttle through the turbulence of space, I guess Zhang Yu's goal is to recover those exiled dimensions." Reed replied.

Susan, who was next to her, also nodded and added. "Tony, you're not from this universe, so you don't understand, the battles of the past ruined a lot of things, including the connection between the reality dimension and other dimensions."

"Who said I don't know, I've always watched the replay of that battle as a sleep story." Tony Stark retorted, and then he pondered for a moment before speaking again. "But it's better to follow Zhang Lu through the dimension."

"Why?" Reid was a little curious.

"It's not that you don't know Zhang Yu, it's too dangerous to take risks with him, I'm still having those scary nightmares, for the sake of my physical and mental health, I think it's better for me to try my luck with Kara."

As if thinking of some bad memory, Tony Stark looked at Reed and Susan not far away in front of him, and sighed repeatedly.

God knows how much courage it took to work with Reed and Susan after that incident.

Although he knew that the two people in front of him were not the same as the zombie versions of his own universe, Tony sometimes subconsciously avoided being alone in a room with the couple.

If it weren't for the fact that this time the task was heavier, and everyone else in the Mystery House had their own jobs, Tony would never have come here.

Of course, he still kept a backhand, for example, Reid Richards and Susan didn't know that Tony had opened seven secret passages in this laboratory.

"You're right." Reed pursed his lips in agreement.

Zhang Yao's adventure is indeed a fantastical feat, and before meeting Zhang Yao, several people present had never imagined that there would be so many complex, crazy, and desperate universes in this world.

Like Tony Stark, Reed Richards will never forget the self who was infected as a zombie in his life, and the video scam that crossed the parallel universe left an extremely deep impression on him.

"So, I'd better ask Kara how it's going, I've heard that their mission is to trade across the universe, and I'm sure I, as the top leader of Stark Industries, can do this kind of pediatric work."

Tony Stark straightened his chest and said confidently.

"I see, you're just curious about how that universe is different from ours." Susan smiled and shook her head, then spoke. "Hurry up and get to work, we're running out of time."

"Please, we're outside of time now, how can we not have time~"

Although Tony Stark said this, his movements were not slow, and he soon came to the front of the locomotive and began to check the energy parameters on it.

With information and some inspiration from Shazam, the group finally decided to take the shape of a train.

At first, Tony Stark wanted to build an aircraft carrier or a warplane, but because it would take a long time to build that kind of thing, and if it was too large, it would be prone to greater resistance in space turbulence.

Because of this, the design of the pirate ship was also rejected by Susan and the strict Reed Richards, which made Tony Stark depressed at the time.

Looking at the two-meter-tall locomotive, Tony Stark couldn't help but speak after carefully checking the parameters.

"If you want me to say, this train might as well be replaced by a phone booth."

"We've talked about the design of the device's appearance before, Tony." Reid Richards focused on the job at hand. "I know it's going to annoy you to reject your design, but you have to understand that this is Zhang Yu's request after all."

"Zhang Yu just reminded us that there was a train in Shazam's original crossing device, and he didn't say that we must build a train to come out, according to you, there are any doors in the Eternal Rock, should we make a door by the way?" Tony rolled his eyes.

"The design concept of the portal is not the same as the dimensional crossing device, strictly speaking, it is a work of magic, and what we need to do now is to use rigorous science to prevent the space from collapsing and being trapped in another dimension." Reed said seriously.

"But I still don't think this locomotive has any imagination at all." Tony stroked his beard.

"But it's really the most suitable piece for us."

Reid Richards' head reached Tony Stark's side, his body still in place.

"As long as we succeed in developing a dimension-crossing locomotive, then we can connect it to the back at will, install it when we use it, remove it when we don't use it, and switch it freely."

Although he knew that Reed Richards was right, Tony Stark still had some nostalgia for his galactic battleship.

"Okay, I know you're a little disappointed, how about I let you name this device?" Reed said suddenly.

"Really?" Tony Stark raised an eyebrow.

The naming right of a product is sometimes the same as the authorship right, which is very important to them as scientific researchers, even if they don't value it anymore, but Tony is still very interested in naming this thing.

In this regard, Reed said that it did not matter.

"Really, as long as you don't come up with weird names."

"How about I decide to call it the Hogwarts Express?" Without the slightest hesitation, Tony Stark gave his own answer.

"Well, it's a strange name, does it have any special meaning?" Reid was stunned for a moment and commented seriously.

"Are you kidding me, you don't even know the name?" Tony Stark, on the other hand, was shocked.

"I'm sorry, he's a nerd." Susan shook her head, then explained to her husband. "Hogwarts Express is the wizarding train in Harry Potter, and you have accompanied me to watch that movie, have you forgotten?"

"I seem to be a little impressed." Reed opened his mouth. "But I can't remember why."

"That's probably because you fell asleep in the movie theater when Harry Potter first received the letter." Susan said speechlessly.

"Ugh"

Swept away by his wife's eyes, Reed retracted his neck a little embarrassed, and then he immediately picked up the circuit board in his hand and changed the topic.

"It's finally done, as long as the last space radar is installed, this my brother monkey express can be activated!"

"It's the Hogwarts Express." Tony lifts his forehead.

But as if he hadn't heard, Reed Richards stretched out his body and quickly came to the bottom of the locomotive's front car, and began to install the strange device.

Acting in the spatial turbulence is a very dangerous thing for anyone, after all, space and time are not the same, the turbulence of time will only send people to an unknown timeline, but the spatial turbulence will crush and decompose people.

It took a long time for Reid Richards to get the chocolate box-sized device in his hand, and when he was developing the device, Tony Stark even put an air conditioning system and a home theater on the train by the way.

Just as Reid Richards was putting the finishing touches on the installation, the doors to the lab suddenly opened.

I saw Zhang Yu, whose face was slightly pale, slowly walked in.

"Didn't bother you with your work, I wonder how far the progress of the Dimensional Crossing Device has come now?"
