Nightwing arrives at the abandoned chemical factory that Charlie calls it, one of the industrial ruins on the border between Gotham and Brighthaven. At its peak, it was home to several chemical plants, but with the decline of industry, it was gradually abandoned, leaving only this abandoned building and toxic land.

Nightwing crouched down to collect some of the soil components from his feet, which, if he guessed correctly, should be consistent with the soil that Batman had found from Charlie's grocery store and the abandoned warehouse in the Met.

The slightest glimmer of light in a pitch-black building is very conspicuous. Nightwing took advantage of the darkness to the vicinity of the only factory with a little light, and several heavily armed men patrolled outside the factory, looking at the familiar costume Nightwing and narrowing their eyes:

[Sure enough, it's a scarecrow's subordinate]

Carefully avoiding the patrol, they came to an abandoned house closest to the factory, and found that the factory was surrounded by metal mesh. He didn't think that the weirdly colored metal mesh was just a basic insulator. After looking around the environment, Nightwing chose the nearest abandoned water tower, used the hook to hang to the highest part of the water tower, took out a special portable glider suit and put it on, roughly estimated the wind direction and strength, found an appropriate direction and ran a few steps, and slid from the high water tower to the target factory by night.

The high-tech materials allow him to glide quietly, and the state-of-the-art aerodynamics allow him to easily change direction in the air, the only downside is that when he falls, the wings that don't fit too well are a bit troublesome.

"Maybe I should have added a cape design to my next outfit."

Only then did he think that Batman's thankless cape was still beneficial, and quietly landed on the roof of the factory, and after putting away the gliding suit, he carefully lifted a tile and looked down through the gap. Nightwing's vision was limited by the small gaps, and several of the large machines in the factory had apparently ceased to function. However, as far as Nightwing could see, there was no scarecrow's classic gas storage container.

“... Odd? Someone is guarding it, why is there nothing in it? ”

Nightwing looked at the three guards in the factory who were sitting boredly playing cards together, and there were only seven of them, including the few patrolling outside. If this is the current stronghold of the Scarecrow, there will be a bit of a shortage of people. Did you guess wrong?

Just as Nightwing was thinking about whether he should go down and knock over a few people below to ask about something, and then take a good look at the factory, a car suddenly drove towards this side in the distance.

Carefully lying down and hiding his figure, Nightwing watched as a person got out of the car and said something to a few patrolling people, the figure of that person was a little familiar to him, but he couldn't remember where he had seen it for a while.

After a few words with the patrolman, the man walked into the factory, the empty factory was conducive to the transmission of sound, although the voice was a little small, but Nightwing still heard the content through the crack:

"How's the preparation?"

"It's all here, when will the head be pulled?"

"In the past two days, there has been something wrong with the partner, and there has been no movement in the past two days."

"No, but the bat seems to have noticed"

"It's okay, did you find that Charlie guy?"

"No, that guy has a very strict mouth, and he's beating us for fear of beating us to death, so let's get some confession on the head."

“.... You also know that the bat noticed this, the head won't come out for the time being, don't say it, we can't find it, and the bat can't find it, so don't let him run away, I'll go and see him."

“ok”

A minion stood up and walked to the opposite wall, pressed a power switch, and the invisible door on the opposite wall where the man came in slowly opened, because he couldn't see the panoramic view of the house, so Nightwing noticed that there was a difference in the size of this factory from the outside and from the inside. The angle of the door happened to be out of sight of Nightwing, and when he was wondering if it would be better to change positions, he heard the man's voice:

"Be optimistic about him, and he will be ready to haul the rest of the goods in the first two days"

After the instructions, the man quickly left the place in the same car he had driven at the beginning.

Nightwing sat on the roof and pondered the conversation between the man and the minions, the first thing in the man's mouth was a scarecrow, and it seemed that Batman had noticed his involvement in this matter, and the scarecrow had already noticed it.

“... Who are the partners? Luther? ”

The man's statement that something was wrong with his partner made Dick a little concerned. Lex. If there's a problem on Luthor's side, it's Clark... By the way, Bruce and Clark seem to be busy with something lately...

After pressing the communicator with his finger for a long time, he still turned on the frequency that belonged to Superman;

"Nightwings? How could you come to me"

Superman's voice was accompanied by a strong sound of breaking wind, and he seemed to be flying at high speed in the sky.

"That Superman asked you something... Is there something going on over there in Luther? ”

“... You can ask the cloth.. Batman."

“... He's not going to tell me."

"If you don't ask him, of course his character won't take the initiative to tell you"

The wind is gone, and Superman seems to have stopped flying.

“..... Oh please."

Superman sighed:

"Dick don't be so reckless, sharing information doesn't mean you're bad, even I often have to share information with Bruce, I know you want to prove that you can be independent, but that doesn't mean you have to isolate all the people who can help you"

“.......... Don't call me by my name."

"This is an encrypted signal made by Bruce, I think it's the safest signal in the world, I'm in the stratosphere 10,000 meters above the ground, unless you have someone around you"

Superman's words came with a smile.

“... Nobody"

"Need my help?"

Superman knew that Dick would use Bruce's channel to find him must be in the middle of the mission, so he asked casually, and Dick looked at the few guys who continued to play cards in the factory below, thought for a while, and said:

"Yes!"

Soon the familiar figure appeared behind Nightwing.

"How can I help?"

Superman's claircopy doesn't need to see through the cracks like Nightwings to see everything in the factory.

"You can see the people in the mezzanine behind that wall, no"

Following Nightwing's direction, Superman soon saw a man tied to a chair inside.

"See, what's wrong?"

"There's a secret door button on the wall over there, do you have a way to get people out of it without a trace?"

Superman looked at the button, then at the wall, and thought for a moment.

"I'm fine, but the problem is that the door doesn't have to be very lumpy when it starts and merges, they can't see me but they can see the door"

Superman's super speed is not a problem, the problem is that his super speed cannot be used on the electric invisible door, and the ordinary hinge door is better to say.

"No problem, I just looked at it, it was less than a minute from the door opening to the merge, I'm going to cause some trouble... Forehead.. Can you throw me out of the grid first, no"

Nightwing, who was put on the periphery of the power grid by Superman, thought for a moment, then looked at the four guys patrolling outside the door, and had an idea in a flash.

Soon the sound of gunshots from outside the door attracted the attention of the three people in the room, and the three of them quickly picked up their guns and hid under the nearest glass window to avoid being seen from the outside.

"What's wrong?!"

"It can't be the black bat."

"Shut your crow's mouth, what's going on outside?!"

A guy who seemed to have a small head asked in a loud voice.

The gunfire outside the door soon stopped.

"It's okay! Nervous overly! ”

The sound outside the door came, causing the three people in the room to shout and curse. After putting away the gun, he opened the door and scolded in an unkind tone and asked:

"What? Did the gun go off? ”

"I saw a dark shadow flashing past"

“... Batman? ”

"No, it's a cat, the guy was so nervous he shot"

"What the hell, nervous, be careful not to attract that bat!"

"Don't worry, this is Gotham, there's no gunshot, he won't come"

"It's better to be like that"

................................................

Dick watched with satisfaction at the crowd of people in the doorway, and his powerful foreign aid was now carrying the unconscious guy from the sky.

"Who is he? There are signs of being beaten, and one of the three broken ribs is a bit severe, and it is not life-threatening at the moment."

Seeing Dick busy giving the man a simple check-up, Superman used his super vision to do a check-up, and the man was beaten badly and needed to be hospitalized.

"People related to Charlie"

Dick was relieved to hear Superman's conclusion.

"Who is Charlie?"

Superman doesn't know who Charlie really is?

"Didn't Batman tell you?"

"Tell me what?"

"Charlie may have been the one who pulled the strings between Luthor and the Scarecrow"

"The intelligence peddler?"

"Right"

While the two were talking, the man had a tendency to wake up.

"Hey! Wake up! ”

Nightwing slapped the man's face, forcing him to wake up.

The man slowly opened his eyes, glanced at Nightwing's face, and said disdainfully:

"I don't have anything to tell you."

"It's a tough one, but I don't need it, I've already found Charlie"

Nightwing's words made the man turn his head and stare at him:

"You.. Deceptive"

"Believe it or not, why are they in such a hurry to find Charlie?"

Esma is dead, and Scarecrow's desire to find Charlie as a matchmaker seems a bit outrageous, and Nightwing feels that there must be some kind of connection between the two.

The man kept his mouth shut, not seemingly intending to answer any of Nightwing's questions.

Seeing the man's appearance, Nightwing stood up, patted the dirt off his leg, and turned to leave.

"Just let him go like this?"

A voice came, and the man noticed that there had been a person directly above Nightwing.

"He wouldn't say it, forget it, anyway, we found Charlie, and probably the clue is about the same, Esma probably got involved with the scarecrow for some purpose, and then found Cha Li to test the subject, and Himmler also found him at that time, so he strung Himmler and Esma together; I don't know if Luthor found Esma first or Esma found Luther, but it must have been the thread that Charlie wore, at first I thought that the person who entrusted Charlie to find an abandoned chemical factory should be a scarecrow, but then I thought that it was Luthor who was more likely, and it should be a scarecrow who killed Himmler, and the main purpose of killing Himmler is likely to be to prevent Charlie from being discovered by us and bring out the clues on Luthor's side. That guy was in big trouble unknowingly. ”

Nightwing put together all the clues they knew now. Then after thinking for a long time, he asked:

"Let's match yours"

"Perfect fit"

Nightwing's conclusion surprises Superman slightly, almost exactly as Batman had guessed.

"Wait a minute"

Seeing Nightwing and Superman just about to leave, the man hurriedly called out to stop them.

"What? I've already rescued you, and I want to call you an ambulance? ”

"No, that, Esma and the Scarecrow had a falling out, I don't know the specifics, but Esma seems to have hidden the most critical formula for poison gas"

“.... Scarecrow thought he gave it to Charlie? ”

The man's words made Nightwing fall into deep thought, if so, then the scarecrow's desperate search for Charlie would be over.

"I didn't think I thought it was given to Charlie, but only half of it was given, and Charlie couldn't understand it at all, so he just put the note away"

"Completely incomprehensible?"

"Well, it's like a password, and I was asked to bring it over."

Nightwing suddenly remembered the strange note Bruce had found from the street child leader.

“... Why are you telling me this? Should I trust you? ”

"It's better to tell you than to tell them, we're just eating in this corrupt Gotham, you can get rid of them"

“... I can't guarantee this, but your clues are really useful, take it, go down this side to the road below, you can stop a car and go to the hospital by yourself"

Nightwing pulls $100 out of his pocket and throws it at the man, then leaves with Superman.

"Do you need my help?"

Superman asked, looking at Nightwing's back.

"No, I'll go find Charlie again, and I can handle the rest myself"

Nightwing stepped onto the locomotive and sped all the way in Charlie's direction.
