"Do we have the results?"
"Yes, if powered by a standard Arc Reactor, the 10-ton compact spacecraft we jointly developed with Wayne Enterprises can reach a top speed of 58 km/s. If the acceleration is 10 Gs, which is the average maximum tolerance for astronauts wearing protective suits, it would take 10 minutes to reach that top speed.
Considering the challenges of orbital trajectories due to gravity, the top speed could be further increased, enough to reach the Moon from Earth within two hours. For Mars, it depends on the timing, as both Earth and Mars orbit the sun, so the distance between them isn't fixed, but it wouldn't take too long."
Victor pushed up his glasses, a proud expression on his face.
"A 10-ton compact spacecraft. What if we built a bigger one?"
Qingshui asked.
"Then we'd install more and larger Arc Reactors on the spacecraft. However, even doing so wouldn't significantly increase the top speed, at most a slight improvement. The conventional materials currently available to humanity, aside from miraculous metals like Promethium, can only withstand the pressure of this speed range."
Qingshui nodded, understanding.
Extraordinary metals like Promethium were ultimately rare. As for conventional metals, thanks to the black-tech talents in this world, they were already far superior to those in a normal modern world.
The initial speed of the Voyager probe was just over 17 kilometers per second, and its maximum speed, achieved by gravitational slingshot past Saturn, was only 34 kilometers per second. This new development was far superior.
It was already incredibly powerful.
If spacecraft like these could be mass-produced, colonizing the solar system might be ambitious, but planets closer to Earth's orbit should pose no problem. For more distant places, if desired, resources could be extracted with relative ease.
At that point, traveling to the Moon might be like taking a car to a neighboring province, and going to Mars akin to a long-distance sea voyage abroad, similar to round trips between Asia and America. Even more distant planets wouldn't be out of reach.
This was enough to evolve humanity from a planetary surface civilization into a nascent interstellar civilization.
Mr. Freeze's cryo-technology combined with Tony Stark's Arc Reactor had surprisingly sparked such technological innovation.
There were certainly many other issues, but artificial intelligence and robotics alone could solve most of the problems.
As for materials, one path was to continue researching Nanotechnology, developing stronger materials better suited for interstellar travel. As for the other...
He had to think about whether he could "borrow" a little more from Tony Stark.
For example, the formula for Gold-Titanium Alloy.
This material had low output and was incredibly expensive, but at least it could be consistently produced. Its mechanical energy conversion efficiency and excellent defensive capabilities meant that even an RPG hit would only leave a small dent on the surface.
Such performance was good enough to be considered a low-cost alternative to Vibranium.
"Is it possible to miniaturize the superconducting device and equip it on the Bat-suit?"
Qingshui looked at the superconducting device, now installed and operating under various instrument checks, and asked Victor.
With the superconducting device and the Arc Reactor, his Bat-suit's performance could be significantly enhanced.
"For now, it's very difficult, but there are two possible solutions," Victor replied after a few seconds of thought.
"One is to invent an efficient thermal insulation device, preferably a coating, and modify the energy system inside your Bat-suit. It would require superimposing another micro-energy circuit onto an already established system, which is very difficult. However, if we're willing to dedicate enough time, it should be achievable, but it's quite troublesome."
"What's the other?" Qingshui asked.
"The other isn't as troublesome, but from a technical standpoint, the difficulty will be high. However, I think it will be easier for you to achieve."
"Tell me more?"
"No need for too much detail. As long as you can get Ray Palmer's technology that can shrink people and objects by hundreds of times, this problem can be easily solved."
"That's not an easy task," Qingshui shook his head slightly.
That was The Atom's bread and butter. Ray Palmer's current net worth of billions owed a great deal to this technology, not to mention its role in his heroic endeavors.
If this technology were handed over, anyone who acquired it could use it to find The Atom's weaknesses.
Without this ability, Ray Palmer would just be a highly intelligent but ordinary scientist.
This was tantamount to putting his life in someone else's hands.
Even though the other party had now joined the Justice League through his introduction, the level of trust between them probably hadn't reached that point.
After all, in the DC Universe, heroes like Superman and The Flash, who are overly naive and easily trust others, are truly rare.
The Atom wasn't as embittered, but he was still a seasoned capitalist.
At most, he was a capitalist with a stronger sense of justice and responsibility.
However, this also meant that negotiations were possible, though the difficulty would be higher.
Perhaps if they were willing to pay a sufficient price, for example, sharing a technology of the same scientific-yet-unscientific caliber as the Arc Reactor, the other party would agree?
The Atom's technology differed from Ant-Man's; the former could become smaller than the latter, but couldn't grow larger like him.
But the ability to shrink things alone was already extraordinary. With this technology, not only could a superconducting device be built on the Arc Reactor, but this technology could also be combined with Nanotechnology.
A micro-robot a few nanometers, or even less than a nanometer, in size could generally only perform one or two simple functions. Due to complex processing, it was also difficult to program them.
But creating a robot a few centimeters in size with complex functions was much less difficult.
What if that small robot were then shrunk to the nanoscale?
Or even the sub-picometer scale?
This level of precision in micro-technology, combined with strong AI, would be incredibly useful in fields like material science!
Qingshui finally understood why Batman always seemed to sneak around and acquire technology from others.
Because integrating the various advanced technologies from these heroes and villains could create even more advanced technologies!
"I'll keep this in mind and talk to Palmer when I have the chance. However, we can definitely try more with the first item. Don't forget we just got the electron beam technology for producing Nanobots from Wayne Enterprises."
Qingshui said to Victor.
Meanwhile, as he and Victor were discussing.
Somewhere in the Antarctic ice fields, a wormhole appeared, and a man in a tattered Bat-suit crawled out, holding a small bottle labeled Bat-Shark Repellent.
"Finally, I'm back!"
Batman looked haggard, but he forced himself to stand up from the ice field.
This journey through the multiverse had nearly exhausted him.
First, he arrived in a universe where Batman had already died, and he battled wits with the Joker there. Then, with the help of Alfred and Catwoman from that universe, he defeated the Joker, found Mister Terrific, and obtained a way to travel through the multiverse.
Next, he encountered many different Batmen across multiple multiverses.
There was Batman active in 1989, whose suit prevented him from turning his neck, Vampire Batman, World War II-era Batman, an elderly Bruce Wayne from the future and his successor Terry McGinnis (Batman Beyond), and even a universe where Superman ruled the world and Batman became Superman's Puppet, among others.
Although he lost an arm during this process, he also obtained a high-tech prosthetic arm from a Batman in another universe, and a Utility Belt made with spatial and Nanotechnology, packed with all sorts of items.
It was with the help of these items that he was able to traverse multiple multiverses, using key events in each universe as symbols and time as a numerical value to calculate his own spacetime's position on a higher dimension. This allowed him to finally pinpoint his location and successfully return.
The Bat-Shark Repellent in his hand was something he pulled out during his last transmigration to escape a dangerous situation he encountered.
"The Bat-predecessors from other universes are truly amazing. How did they come up with something so seemingly insignificant, yet so crucial in critical moments?"
Batman marveled, looking at the shark repellent spray in his hand, which was almost empty, and then looked around.
"I'm out of compressed biscuits. Next, I need to find food here, regain my strength, and then find a way back to human society and return to Gotham."
He wondered how long he had been gone and what Gotham was like now.
Nightwing should temporarily take over Batman's responsibilities, and Alfred and Lucius would safeguard Wayne Enterprises in Bruce Wayne's absence. With Watt and the Justice League around, there shouldn't be a big problem.
At this moment, Batman suddenly thought of the first parallel world he visited.
A universe where Batman had died, but the Joker was still alive.
This world hadn't had a Batman for a while, but the Joker was also long dead, so there shouldn't be any issues, right?
While Batman was still surviving on the ice, trying to outwit polar bears and find his way back to human society.
In a certain abandoned well in Gotham.
This had become Harley Quinn's new base after the Joker's death, and she'd even found a rat here to befriend.
Even if it was kidnapped here.
"Tell me, where did the Joker hide all the stuff he stole before he died?!"
A person with a face like a black skull came to the well as usual, threw down a stale piece of bread, and said to Harley Quinn.
This was the first person Qingshui met in this world, his old friend Black Mask.
"You bitch! If Mr. J were still here, he'd rip off that burnt-toast face of yours, then draw a smiley face on it with ketchup and chili water, and then he'd ** you, and then * you again, and finally feed you pig-breeding aphrodisiacs, sprinkle you with pig-scented water, and throw you into a sow pen to be **** by the sows! And, I'd use the whip Mr. J gave me to…"
Black Mask watched the Joker's insane ranting below with a cold expression.
"Your Mr. J is dead."
Two years ago, during the various struggles between the Joker and Batman over the Titan Formula, the Dionysium in his body reacted with the Titan Formula, causing cancer.
Finally, in a fight with Batman, the Joker's sneak attack on Batman led to the destruction of the antidote Batman had prepared for him, resulting in the Joker's death.
At the time, Batman was about to pull out the antidote for the Joker, but the Joker thought Batman was pulling out a Batarang…
"Mr. J is the greatest! He'll definitely come back! That cowardly bat couldn't possibly kill him! He tricked everyone, playing hide-and-seek with us. He's definitely preparing a surprise for that ugly bat!"
The Joker's insane ranting continued.
"Nonsensical babble. I really don't understand why you think he's still alive. He's dead. That bat saw him die with his own eyes, and then he was gradually forgotten by everyone. Except for those like me who remember the money from the banks he robbed, only a fool like you would still remember him."
Black Mask threw the entire stale piece of bread down, his voice cold.
"You're full of shit!"
The Joker threw the bread back, hitting Black Mask precisely on the head.
"You're dead! My Pudding will burst in like Rambo with a painted face, fill your head with lead, then he'll hold me close and passionately kiss me, and after we're done, we'll throw you out and chop you into tiny pieces, then feed you to Bobby!"
"Who's Bobby?"
"It!"
Harley held up the rat in her hand, which was eating breadcrumbs.
"I've lost my patience."
Black Mask wiped the breadcrumbs from his face and pulled out his pistol.
"It's getting harder and harder to survive as a gangster in Gotham these days. Either you become Watt's dog, or Batman puts you in the hospital. So I need this money now to get back on my feet."
"This is your last chance..."
*Bang!*
A crowbar, painted in red and green, struck Black Mask's head with a heavy thud, knocking him out.
"Oh! Darling, so you're here too. I heard I was supposed to be dead in this world?"
A pale face with a lipstick-painted smile appeared at the entrance, grinning at Harley Quinn below.
Batman had returned to this universe, and from the world where Batman had died, the Joker had followed him.
To the Joker, a world without Batman to play his twisted games with was simply too boring. Heaven knew how he'd endured it before.
But then, fate gave him a surprise!
A new Batman from another universe!
Yet, just when he thought the fun would resume, Batman decided to leave!
So, he chased Batman and ended up here.
"Mr. J!"
Harley Quinn excitedly spread her arms, delighted, and spun around with Bobby the rat in one hand.
"I knew you'd come back for me!"
