From Superman's perspective, this is how things actually went down -

The last scene in his memory was still the dark Apocalypse Star, the lights on Earth, and the smoke that filled his nose. Alice's arms were so soft, they were shoulder to shoulder, and there was a Superman doll with black eyes in the middle. Then the system activated the sleep mode, and he took the initiative to let his consciousness fall into an endless dark dream.

Sleep is not necessary for a Kryptonian who is exposed to yellow sunlight for a long time, but Superman likes to rest like an ordinary person. Deep sleep is like flying alone in the depths of the universe, without having to think about anything or worry about anything. He briefly obtains the most primitive happiness and satisfaction that an intelligent life can have, and almost wants to sleep forever and not want to wake up.

——If he hadn't opened his eyes and found himself flying above Gotan, with the Flash, who was free falling and helpless beside him.

"Barry, be careful!" He has been following this Central City superhero for some time. Ever since the first time he flew over Metropolis, Superman has regarded those brave warriors on Earth as his own beacon of progress, so he subconsciously called out the other person's real name, "I'm coming to pick you up."

He stretched out his hand to grab the Lightning Man's arm, but misjudged the distance and his fingertips missed.

Moses:"……"

Wait, wait?!

Whose voice was that just now? Whose is that short stature?!

He had only just come to his senses for a short time, and he didn't even realize that his clothes no longer fit him. His movements were a little too aggressive, and a gust of cold wind blew in through his collar, so he bent his hand to save the Lightning Man and pulled up his pants with difficulty.

On the bright side, this outfit is a one-piece and it only makes it difficult to move around, but it doesn't affect the cityscape.

System: "I have activated the emergency energy-saving mode. You shouldn't have woken up at this time. The impact of cosmic radiation is too great. You can't maintain your peak condition. I can only temporarily fix your body at an age that is not very strong but not too old."

"Doesn't your conscience hurt?"

Superman asked angrily in his heart, then suddenly rolled up his sleeves and dived down, grabbing the Flash's wrist just before he came into direct contact with the ground.

"Thank God!" Barry breathed a sigh of relief. "Thank you for saving my life, Lan--uh."

The nickname 'Big Blue' came out of his mouth but he swallowed it back after he realized something was wrong with Superman.

"When did you wake up? Where are we? And if you'd like to be polite, how old are you now?"

Half an hour later.

"Thank God."

The Flash bought a set of children's clothes from the clothing store for Superman to wear, and he also changed back into his normal clothes. The two of them walked on the streets of Gotham and said, "I almost thought I accidentally went back to the past when you were still a child."

"I wasn't Superman then, and you wouldn't have known me."

The boy following Barry Allen looked no older than ten years old, with baby fat on his face. Only the curls on his forehead still stubbornly revealed his identity.

Superman's tone was as steady and reliable as when he was speaking seriously, but the immaturity in his voice diluted the serious atmosphere of the conversation a little.

"I'm sorry. I'll pay you back for the clothes, but I'll have to wait until I get back... When I'm Superman, I usually don't carry my bank card with me. This is Gotham, or the Gotham of a parallel universe. We have to find someone to help us."

"How do you know that?"

The blond young man raised his hand to smooth back his hair, and looked around curiously. "I don't see how this is different from our world. But if this is really Gotham, why don't we go find Batman? By the way, would you like some ice cream? I saw an ice cream truck at the corner of this street."

"The premise is that we already know Batman in this world."

With a calm mindset that there was no need to rush since they couldn't go back, they each had an ice cream cone in their hands after walking out of the alley.

The system once introduced that the world where Moses lives is a special one among countless universes, but it also did not provide detailed popular science on how other parallel universes develop.

But he guessed that other than Batman and Superman having their own, real-life growth experiences, there shouldn't be any surprises, right?

So in response to the Lightning's suggestion, he compromised and said, "Let me first see if his base is still in the original place."

After some exploration, they got good news and bad news.

The good news is that in this universe, the Gotan vigilante still uses the code name 'Batman', and the villains seem to be a group of psychopaths and criminals.

The bad news is - this Batman is a two-gun man.

"Cool." As they hid in the bushes and watched the Gotan Knight and the Ugly Girl fighting for 300 rounds on the viaduct, the Flash whispered at super speed, "I think the timeline here is a bit behind. Batman looks quite old, but his skills are still pretty good."

"Wait a minute." Superman could keep up with his speed, "Why do I feel that this is not Batman."

There was genuine confusion in the Son of Krypton's blue eyes: "Batman shouldn't use a gun?"

"He just said he was Batman," said the Flash, "and not only did he use a gun, he had several."

“…”

Something must be wrong. The problem was, because the world was different, Moses wasn't sure what it was.

Barry still didn't realize the seriousness of the situation. He counted on his fingers with great interest and analyzed: "If the Batman in the two worlds is different, will we see different versions of you and me? You can hear others calling your name, right? Wait - why don't we call ourselves Superman?"

As he finished speaking, the two of them, big and small, looked at each other silently in the bushes.

"Did I just speak? Superman!"

Still no response.

After a while, the Flash raised his voice again tentatively: "Superman! We need help!"

"I heard it," said Moses, licking his ice cream cone. "I came over too."

Barry couldn't help but laugh: "But I'm not calling you, brother. Where is the Superman of this world?"

"Maybe in the universe."

"You're right. We can't build another spaceship." The Flash nodded. "It's more convenient to ask Batman for help."

After reaching a consensus, the two approached the direction of Batman. At this moment, the vigilante Gotan grabbed the ugly girl's hair and pressed her against the metal beam of the viaduct. In his other hand, he held a weapon and pointed it at her eyeballs to force her to reveal information.

"hiss."

Moses heard the Lightning Man gasp vaguely.

At least he wasn't so naive as to think Batman was a friendly partner.

Superman is even ready to fight if they disagree.

At this moment, the ugly girl was thrown out by Batman by the collar, and the night sky was instantly broken by a woman's scream. Barry's eyes fixed, and the uniform in the ring quickly popped out. Without even a chance to say hello, he ran along the edge of the bridge and brought the person back intact in the blink of an eye.

Batman: “…”

Superman, who was flying in the air and preparing to greet politely, said: "..."

"Hey, Bat." The Flash pinched the ugly girl's neck gently, and she went limp silently. "I never knew you could be so violent towards girls."

The Gotan vigilante looked at them coldly, from the speed that the Flash had just revealed to Superman's feet leaving the ground.

And there was the poor half-scoop of vanilla ice cream that had just fallen to the ground because Barry had rushed out.

"What a pity." Superman looked at the wasted food with regret. Two red lights flashed from his eyes, and he precisely evaporated the water molecules in the butter by just burning the metal red. "This won't pollute the environment, right?"

The Flash knew that he was trying to ease the tense atmosphere, so he immediately said, "It's okay. I can just borrow a tissue later."

Batman chose not to retreat during their conversation, but he also did not attack. After the Flash finished speaking, he asked in a businesslike and conciliatory tone: "Who are you from? Atlantis or the Amazon? Maybe we can talk about a deal."

Another bad news.

Moses immediately realized that the Batman here knew neither Superman nor the Flash.

But if they had appeared as heroes before, then you should have heard their names even if you had never met them. At least you shouldn't be talking to them in a tone that sounded like they were threatened and sitting at the negotiation table with their hands raised.

And why do Atlantis where Aquaman is and Amazon where Wonder Woman is sound like villains?

Barry is a man with a sharp mind, and he is also thinking about the questions that Superman can think of.

After just one second, he shrugged as if nothing had happened: "Don't get me wrong, we are not enemies. We are just two mutants who saw injustice and sought help."

Although mutants don't have a very good reputation in society, they are still better than being suspected members of criminal gangs.

However, Batman asks, "Mutants - what are you talking about? Is this a code name?"

"Of course not... Hey, what's going on?!"

The confusion in his heart snowballed, and the Flash subconsciously looked at Superman with a look that meant: What should I do now?

Superman's innocent face wrinkled. He thought for a moment, then flew a little higher and raised his hand to hold Barry's shoulder. At the same time, he slowly said to Batman: "I know you are not Bruce."

As soon as he finished speaking, gunshots rang out. The Batman in this world was simply a synonym for brutality. Two bullets hit Superman's vitals at a tricky angle, and the boy suspended in the air did not move, letting the metal collide with his body and make a crisp sound.

At the same time, his solemn voice, which was inconsistent with his appearance, was still reaching everyone's ears at a speed that everyone could understand and had enough time to think:

"What is your relationship with him? You—"

The boy's Adam's apple moved. He couldn't help swallowing. He couldn't hide the tension and surprise on his face. "Are you father and son?"

"Is that what I understand?" The Flash looked at Superman and then at Batman here, "In this world, the father of Batman over there became Batman. Why does it sound so strange?"

An awkward cough sounded behind them.

"I think so too." Barry Allen, a Central City policeman in this universe who somehow doesn't have the Speed ​​Force, climbed on the crossbeam of the viaduct and raised his hand to greet them. "It's nice to meet you, a Flash who can still outrun the Flash, and a Superman who is at least twenty years younger."

"Me too," said the uniformed Flash. "It's touching that you know our names."

Superman let out an imperceptible sigh, for the increasingly chaotic situation, and for the other Batman, Bruce Wayne, who wondered if he was willing to see this scene.

But he quickly calmed down, hid his troubled side, turned around and smiled at the policeman who had struggled to climb up the viaduct: "Thank you. I know you have questions about the current situation, and so do we. Mr. Batman, can we go to the Batcave to talk?"

No one knows what expression the vigilante Gotan had under his mask towards these uninvited guests.

It's impossible to be too friendly anyway.

Obviously, Superman revealing the location of the Batcave made this middle-aged man more jealous.

But he couldn't do anything. The black-haired, blue-eyed boy picked up his hood and flew away without saying anything. The ground was getting farther and farther away from his feet. The Flash carried his other self on his back: "Superman! How about we compete to see who gets there first?"

Barry: "Wait! You're still carrying me!"

"Superman also brought Batman with him. But, it suddenly occurred to me that I don't know where the Batcave is."

Thomas Wayne heard the young man above him chuckle happily, as if the conflicts and hostility had never happened. This powerful superpower called Superman was sometimes too mature to be a child - even the team he formed with the Flash was vaguely led by him.

But now Thomas was suddenly not so sure about his guess about age.

After all, there are too few adults in this world who still have hope. When Superman smiles, his eyes, reflecting the world, seem to be shining.

The older vigilante's shoulders involuntarily relaxed a little.

The posture of flying with a cloak carried by him is not suitable for exerting strength. If it happens again next time, he will definitely refuse.
