American comic Gotham, the sheriff of Arkham

Batman jumped up from the ground, covered the injury on his chest with his cloak, and looked at the man who was floating in the air like a god, the guardian of Metropolis - Superman.

"Uh... need help?"

Superman smiled kindly. He had just dealt with a few robbers who were robbing a store in the next block. He heard the noise and flew over, and then he saw Batman.

After studying the materials Gordon provided to Lois, Superman determined that this hero who hid in the dark and fought with violence and fear was on the side of justice.

"Why are you here?" Batman asked in a deep voice. The voice changer on his neck made his voice very low and rough.

"Well, I'm traveling and passing by." Superman is not good at lying, and his main activities are in Metropolis.

Of course, if someone somewhere else called out for Superman and he happened to hear it, he could be anywhere.

Batman looked doubtful, Metropolis was not far from Gotham, and everyone knew that Superman could fly.

Batman even took the time to study this Superman with the Man of Steel. Of course, as an imaginary enemy, Batman has not found a way to defeat Superman unless he makes Superman lose his "super powers".

Superman slowly fell from the air and looked at the charred corpse on the ground with a hint of surprise in his eyes.

Compared to Batman's principle of not killing as his own creed, Superman is a non-killer of all humans. Yes, except for humans, he faces alien invasions, monster actions, and mechanical monster attacks.

The heat ray swept through without any pause, directly cutting it into several pieces, and its killing rate was comparable to that of Ultraman Ace.

Well, actually Batman is similar. According to his no-killing principle, aliens are not human.

"You're not in good condition. Do you want to go to the hospital?"

Superman turned around and looked at Batman. With his X-ray vision, he could clearly see where Batman was injured.

However, what surprised Superman was that Batman's true identity was Bruce Wayne. Well, a bulletproof helmet could not block Superman's ability of perspective.

Moreover, even in Metropolis, Clark, the Superman who is an investigative reporter and writes news for newspapers, is well-known. The Daily Planet even reprinted the news of Bruce Wayne's return.

"No need!" Batman refused directly. He didn't like Superman's gaze very much. It felt like he was not wearing any clothes.

This feeling of being seen through made him very uncomfortable.

"Okay." Superman withdrew his gaze apologetically. He usually didn't use his X-ray vision very often, this time it was purely out of curiosity.

After reading a lot of information about Batman, Superman was looking forward to seeing Batman. Perhaps it was because he was lonely and he was the only one doing justice, and suddenly he discovered that there was such a hero dedicated to the cause of justice.

Superman also wanted to make friends because he felt that they would have a lot of common topics.

However, Batman's attitude is to keep people at a distance.

The moment he became Batman, Bruce Wayne had already put life and death aside. Only Batman was real.

Bruce Wayne is just a shadow of himself beneath the masses.

The two looked at each other for a moment, and the Batmobile outside the alley drove in, the headlights shone on Batman's back, and the roof slid open.

Batman jumped up and landed on the Batmobile, and as he got off, he turned and looked at Superman.

"Welcome to Gotham. Don't go out at night."

After giving a friendly warning, Batman climbs into the Batmobile and turns off the autopilot.

Batman gritted his teeth and coughed, his white teeth were stained red with blood. He needed to find all the information about the guy before. This unstable factor became his biggest enemy.

The Batmobile left here, Superman looked up at the sky, his cape fluttered, and the whole person flew upwards.

"So, is this thing dangerous?"

Naegi stood behind the cabinet and stuck his head out to ask Nygma.

Nygma held the green test tube in his hand and looked at him speechlessly, "Are you so scared?"

"You didn't say this thing would explode! Is this an alchemical potion or an alchemical bomb?" Miaomu was even more helpless.

The Alchemical Code has been almost completely deciphered by Nygma. It should be said that with the Riddler's high IQ, as long as he doesn't focus on guessing riddles, he is an absolute strong man anywhere.

Although the code was cracked, making those alchemical items is extremely difficult, just the materials alone.

It is often promethium metal, Nthium metal, Amber gold, or even the divine gold, magic stone, energy crystal, magic clusters, and abnormal compounds needed to make artifacts.

After just one look, Miaomu was stunned. Each of these materials was rare and precious. They could not be bought with money, and he wanted to get these materials.

The only thing Naegi could think of was to sneak attack the magicians' lairs, or simply raid the home of Hephaestus, the god of fire.

The former would trigger hunting operations in the magic world, and the latter would cause punishment from the gods of the Olympian pantheon. Maybe Wonder Woman would come with a sword and cut the seedlings into pieces.

"This thing is relatively stable. The last bottle was an accident. It might be a problem with the materials. There are so many exotic plants there."

Nygma casually shook the test tube in his hand, which made Naegi's heart tremble. He was not worried that this thing would explode.

Miaomu was just worried that Nygma would be killed in the explosion. After all, the bottle just now directly blew up the metal table in the laboratory.

"Don't worry, it won't explode." Nygma placed the test tube on a shelf on the side and spread his hands to show that it was harmless.

Miaomu wiped the non-existent cold sweat from his forehead and walked over. They were in a secret base.

Just like Batman’s Batcave and Superman’s Fortress of Solitude, Miaomu also built a secret base, or to be more precise, an air-raid shelter.

This was excavated during the Cold War, but with the end of the Cold War, no one knew about the air-raid shelter here anymore.

This place happened to be in the Arkham District, and was right below the asylum, with the highest terrain protection layer above it. If Otis hadn't searched thoroughly here, they really wouldn't have been able to find it.

However, as time went by, some parts of the air-raid shelter collapsed, but with the reconstruction plan of the asylum, Nygma deducted another sum of money from the budget.

The air-raid shelter was simply renovated. The design of the place was quite good and it was a large place that could accommodate hundreds of people. However, only half of it was built and the rest was not completed.

According to Nygma's inference, it is very likely that the construction of the air-raid shelter was stopped halfway when the nuclear crisis occurred. Now that the biggest crisis was gone, the project naturally stopped.

At least in Gotham's library and the sewer management design drawings of the Health Bureau, this air-raid shelter does not exist at all.

But this is also good news. Miaomu plans to set up his own engineering team to renovate this core base.
