Three-stream detection simulator

In December, during the Christmas holiday, there was a light snowfall in Gotham. Harleen Quinzel finished watching the latest season of Disney's crime drama, which is said to have been written by Hercule Hugo. She rolled around on the bed twice out of boredom, hugged the quilt and shouted in a long voice at the ceiling: " So boring——”

Her red-haired friend, who was sitting next to her against the wall and was correcting student papers on his lap, said, "Where is your Bai Yueguang? He didn't invite you to hang out during such a long vacation?"

"He's missing!" Harleen complained while pinching the corner of her pillow. "I haven't seen a single piece of news related to him for seven months, only the gossip circulating in Gotham recently..."

Ivy: "The one who said he kidnapped Robin and was chased by Batman and had to hide?"

"Huh? No." Harleen broke her fingers, "The version I heard is that he once offended prosecutor Harvey Dent, and Dent encouraged Bruce Wayne to vote for him for next year's election. My pudding. (Hercule) didn't want to see his enemy trying to convince Batman to side with him. As a result, Dante bribed Robin's girlfriend, so Robin betrayed Batman when they were talking about a cooperation agreement, but he didn't. Come to think of it, Pudding actually kidnapped Bruce Wayne in advance to threaten them all, which would explain why Baby Bruce hadn't been seen in public for months."

This explains shit!

Foreigners coming here have to figure out the relationship between the characters for three minutes.

Ivy pushed down the flat mirror on the bridge of her nose and raised her head to look at Harleen. She couldn't tell whether the other party was serious, but it didn't matter. She lowered her head indifferently and said while writing and drawing on the paper: "Then after I finish correcting this shit, we will go out to have some fun."

"Yeah!"

Harleen cheered, took out the paper with the lowest score and threw it into a ball on the wall. The professor behind not only did not stop it, but also showed a very relieved expression.

An hour later, Harleen dyed her hair, put on heavy makeup, and walked out onto the street wearing a light red and blue down jacket and tight-leg jeans. Behind her, Ivy stretched. Her serious suit was instantly torn apart by plants, and her body was wrapped by rapidly growing vines. They were woven along the body-hugging curves into an elegant and beautiful dark green evening gown.

However, this outfit is particularly eye-catching in the sub-zero temperature of Gotham, causing passers-by to look this way subconsciously. Harleen smiled and gave them her middle finger, and said crazily: "Hey, don't just look at me, come closer, handsome~"

The citizens of Gotham, who know how to seek advantages and avoid disadvantages, stayed further away after hearing the news. Harleen's smile widened, she strode forward briskly, and soon arrived at the place where she planned to have fun——

A game arcade.

This store is holding a Christmas promotion event, the discount prices are very exciting, and the queue to buy game coins is very long. The music outside the door was deafening, the neon lights were bright and blinding, and the sounds of gunfire and restricted screams occasionally came from the loudspeakers of a few machines, but none of these could conceal the fact that it was a game arcade.

With no expression on her face, Ivy was pulled by Harleen and squeezed through a group of teenagers queuing up, and sat down in front of the machine they often played with.

Harleen rubbed her wrist, raised the controller made into a baseball bat shape, and asked Ivy: "Are our records still there?"

Ivy controlled the vines and clicked on the screen, and said in surprise: "No more, it was broken again."

"ID or Robin?"

"right."

"Fuck!" Harleen cursed, "I'm going to use this stick to push Robin to the ground and beat him half to death today!"

Ivy's desire to win became a little serious. She bent down and hung her hands on the buttons of the game console, and said in a cold voice: "I'm here to help you."

**

"...Bai Yueguang...going out to play?"

"...missing..."

"Batman is after...?"

"My pudding."

Damian from Pingxin Universe frowned tightly when he heard this.

After he met Poison Ivy last time, he left a bug in her bag. He originally thought he would find something, but he didn't expect that Ivy actually went to school every day to teach and educate people. Her extremely dangerous plant-controlling device Superpowers have completely become auxiliary teaching aids for classroom demonstrations.

And despite her numerous declarations that she wanted to assassinate students, the warrior who arrived late and left early in her class and had the lowest grades in her class still lived until Christmas.

Seven months passed in the blink of an eye, and the bugs were almost discharged without any accidents. Damian thought that the investigation could be temporarily suspended.

As a result, today, he turned on the channel on a whim and heard a conversation between Poison Ivy and Harley Quinn mentioning a dangerous person who could not be ignored:

——That is the object of Harley Quinn's long-term obsession, Batman's greatest enemy, and a nightmare that spreads fear to countless Gothamites.

clown.

However, because the battery of the bug was in critical condition, the messages collected and transmitted over long distances were always intermittent and unclear. Damian was far away at the Assassin League headquarters and had no time to go back and replace it with a new one, so he had to make do with listening.

Judging from the few keywords captured so far, Damian guessed that the general meaning was that the Joker escaped from prison again, and Batman was trying to arrest him.

However, the latter part is more confusing. Damian suspected that he hadn't heard everything, otherwise what would it mean to have 'The Joker trying to convince Batman to side with him'?

How could Robin betray Batman in front of him? ? Are they acting?

What is the Joker kidnapping Bruce Wayne? ? ?

Of course, Damian thought there was nothing wrong with understanding ‘my pudding’ as the Joker, so his mind raced in a strange direction, and he thought again sincerely:

There must be something wrong with this universe!

Fortunately, some things seem to have not changed.

In order to better receive the sound from the bug, Damian ran to the best signal position in the entire Assassin's League: a single room in the men's bathroom.

There was no one here during the day, so he quickly dodged and locked the door to continue listening.

At first, it was the rumbling music that reminded Damian of Harley Quinn in another universe. She likes to play disco music at the maximum volume at the crime scene, as if she was afraid that others would not know she was here, and then hold a bloody party with the Joker and the group of crazy people as if she was high.

Sure enough, the next moment, faint gunshots and faint cries for help came from the headphones.

Then, against the backdrop of various background sounds, Harley's particularly sharp shouts sounded, which seemed angry and contagious.

She said, "Fuck! I'm going to pin Robin to the ground and beat him half to death!"

Damian subconsciously calculated who his father's assistant was at this moment.

If nothing unexpected happened, it was Jason Todd.

"..."

Two-Face is going to be re-elected, and the two universes must be consistent in whether Red Hood dies first and lives later! ! Is it to prevent him from lacking material to tell his own hell jokes in the future? !

At this moment, Damian felt a strong anger at the invasion of his territory. He couldn't stand the repetition of the shameful history that happened in the Bat Family, so he immediately planned to go back to Gotham.

But before that, there was one thing that needed to be dealt with urgently: although he failed to catch Hercule Hugo's illegal crimes in the past six months, he successfully contacted the parallel universe. Before returning to Gotham, he had to report the situation to his biological father, the Batman of the parallel universe.

"You said you met the detective that Bart Allen mentioned. He now lives in the Assassin's League. Many years ago, he participated in a global war named "Strange Stories" with extremely tight news blockade."

Amidst a group of questions about "Why were you in the bathroom, Damian?", the Batman of the parallel universe said thoughtfully: "It is indeed worth paying attention to, but don't be preconceived. Anything can happen in the parallel universe."

Damian stood up straight and talked about his major discovery just now. Sure enough, the conspiracy of the "Joker" made some family members look worried, and the rest sneered.

"If you can help, it's better to help." Barbara Gordon, who was once disabled by the Joker in the parallel universe and stood up again with amazing perseverance, said, "Some tragedies are enough to see once."

"You don't have to tell me." Damian replied, "I'll take care of it."

With his assurance, the Batman of the parallel universe told him to contact at any time, but the communication was hung up. Someone was knocking on the door of the single room outside, and it seemed that it was time to listen to the radio station every day.

It turns out that the toilet of the Assassin's League has a new use.

Damian couldn't take care of both ends, so he left a bug in Hercule's place, and then returned to Gotham without stopping across the earth.

He focused the first step of the investigation on Arkham Asylum, hoping to collect clues from it during the Joker's hospitalization and escape.

The intensive care unit of this universe's Arkham was much colder than Damian remembered. Most of the people living there were some evil and cruel but limited thugs, who were not even second-rate among the super villains in Gotham that had clear levels in the past.

The only person who distracted Damian was the Riddler, Edward Nygma.

He sat in the prison, absent-mindedly solving the puzzles in the latest issue of the newspaper. The doctors tried to use this method to keep his mental state stable, but Damian could see that these simple questions didn't even occupy 10% of his brain.

There must be a more interesting and huge riddle that always bothers him, so that he can stay in the room honestly most of the time, relying on the running mind that is opposite to the silent body to analyze and imagine bit by bit.

When Damian passed by, the riddle man briefly raised his head and looked at him, and suddenly said: "There is a question you can never give a definite answer to - that is your current state, bird."

This is a pun, saying that Damian is confused about the current situation, and "a question you can never give a definite answer to" is also a classic riddle. The answer is "Are you asleep?" to express the irony of the riddle man's roundabout way.

Without waiting for Damian to respond, Edward Nygma in the cell laughed gloatingly, pretending to be very kind and pointed out: "Are you here to find the clown? In order to take care of your brain, I won't tell you the riddle. Just walk forward 200 meters and turn right. You're welcome."

Damian was too lazy to pay attention to him and fast-forwarded to the destination. The Joker's cell was exactly where the Riddler said it was, but the way the items were placed inside was very strange (items of the same quantity were placed together), and the other daily necessities and facilities were a bit too complete. It didn't look like a cell for a highly dangerous lunatic at all, but more like a temporary residence specially prepared.

Not only that, it looked like no one had been in this ward for a long time.

Damian observed in confusion for a long time, but he had no answer. He went back and caught a guard and asked, "Who is in charge of the Joker here?"

"Don't kill me, I tell you, it's Batman!" The guard trembled under his blade, "I swear, Batman has taken over the Joker from the beginning, and none of us has the right to approach the corridor where the Joker's ward is... This is the truth, no matter how many people you ask, you will get the same answer!"

Damian knocked the loser unconscious, and suddenly remembered the words of Harley Quinn in the eavesdropper:

"My pudding doesn't want to see the enemy take over, so he tried to persuade Batman to stand on his side..."

Damian a day ago sneered.

Damian twelve hours ago thought Harley Quinn was crazy.

Damian ten minutes ago still disdainful.

But Damian ten seconds ago actually thought for a moment that this might be true.

The Joker won over Batman, and he succeeded.

Is this reasonable? !

After another ten seconds, Damian suppressed his overly dark thoughts. Arkham obviously had no additional clues, and he planned to further look for Harley Quinn and Poison Ivy, who were very likely to commit crimes within a few days.

During this process, the voice of the parallel universe Batman echoed in his mind again and again:

"Anything can happen in the parallel universe...Anything can happen in the parallel universe..."

Damian: No, father, even if it were you, you would not be willing to draw conclusions easily.

The investigation is not over yet, he must have missed some important details!
