Gotham City, morning.

Thick white smoke enveloped the center of the city, like a scene from a biochemical attack in a science fiction movie. The billowing smoke screen rushed to a height of several tens of meters, and when you looked down from the sky, you could only see the tips of a few slightly taller buildings.

The hurricane released by the high-speed rotation of the propellers of the two helicopters stirred up the thick smoke screen, which tentatively circled around the perimeter of the smoke screen, as if not daring to penetrate inside.

What people fear most is often the unknown, and the unseen realm is likely to lurk with unimaginable threats.

"Repeat, it appears that someone carried out a chemical attack on Gotham Midtown."

Far from the center, countless citizens scrambled to flee from the smoke. The police almost poured out of the nest, all wearing gas masks, to maintain order at the scene.

Reporter Vicky Vale stood outside the smoke with the microphone in her hand and said into the camera lens: "It's very noisy and chaotic, and the police are evacuating the area. Fortunately, so far everyone has been successfully evacuated from the affected area. ”

The news host on the TV station reported in real time: "God bless Gotham City." We've just received further information, preliminary reports have just arrived, and Gotham Homeland Security has confirmed after initial testing that the smoke itself is completely harmless to humans. ”

"Harmless?" Vicky wondered.

What kind of terrorists would go to great lengths to poison the city center, only to scare people with completely harmless gases?

Maybe people's panic is that person's purpose? Just to deliberately empty that place?

On closer inspection, the cleared area is a complete circumference, like a stadium, or more like the Colosseum.

"Boom!"

In the middle of the city, the blackened alloy soles of the feet slammed to the ground, hollowing the concrete floor, leaving behind an inconspicuous cobweb-like pattern. Four or five meters tall, the fat black armor stepped forward, and in the center was painted the bat mark, which was almost equivalent to the symbol of the city.

"You think you'll be able to kill me easily? In my territory, in my city? In the cockpit in the center of the giant mecha, Batman clenched his fists and shouted, "Come on!" Welcome to Gotham! ”

How did it come to this?

An hour ago, Wayne Enterprises, Bruce Wayne's office.

For the company's top CEO, Bruce arrived at the office a little early, with the entire building being halfway through at most, and many department employees may not have woken up from last night's dream.

"So, what do you think?" After briefly recounting to Bruce what had happened to him last night, Roy asked, "Do you think Paul Deco is telling the truth?" ”

"I've been paying attention to Dr. De before." Bruce pondered for a moment and said, "I've always been uneasy about him. He's a genius, there's no doubt about it, and the technique of 'healing sutures' is hardly matched by anyone in his field. But at the same time, he's also a madman, all he cares about is his own research, and in order to accomplish it he can do anything to get it done, including working with the Joker. ”

"But we don't have conclusive evidence to point out that they are actually linked." Roy said, pausing, and said, "I have a theory, or a conjecture. ”

"Tell me about it."

"We all know that the Joker has deceived Death again and again." Roy said, "As for the Titan Venom in his blood, which is killing him, he was terminally ill and unable to move freely when he was last seen in Arkham City, and now he is alive and well, and seems to be completely restored to his former self or even more insane. ”

"What are you trying to say?"

Roy gently placed the clear glass tube he had brought out of the truck last night on the coffee table in front of the couch, dripping with the clear green liquid.

"This is what Dr. Deco is trying to transport." Roy said, "Barbara and I went through various tests last night and finally understood what Dr. Deco was desperately looking for. Although most of the liquid in this tube is insignificant impurities, a trace part of it, which we believe is a completely new element, has never been discovered by humans before. And the closest substance to it is known is the compound from the Lhasalus pool. ”

Bruce seemed to understand something: "Has a regenerative effect?" ”

"Yes, that's what Dr. Deco has spent his life looking for." "Now, with the similarity of this very small amount of ingredients to the compounds in the Lhasalus Pool, we can boldly assume that this substance also has the ability to heal any wounds and heal itself, which is what Dr. Deco wants. I revisited last night where the Joker fell into the water in Arkham City, and speculated on all the locations he might have visited along the waterway. And then I compared a few of them with the ones that Paul Deco extracted from this element."

After a deliberate silence for a few seconds, he continued, "Exactly the same." ”

Bruce also frowned and thought for a moment, then said, "So you think the clown survived with the help of this?" ”

"There's no other explanation." Roy said, "We all know that the only antidote was smashed in the city of Arkham, and the Joker's illness will definitely not survive that night, unless he really happens to find some kind of ancient legendary cure that night." We can even assume that it was the Joker who leaked this information to Paul Deco for some purpose, so Deco secretly sent someone there to confirm whether what the Joker said was true. ”

"Makes sense." Bruce Road.

"But if this inference is true." Roy said in a heavy tone, "We can't estimate how this unknown substance will affect the Joker. We're not even sure if the monster we're dealing with isn't the same one we're dealing with. ”

Bruce frowned, not saying a word.

What happened in the next moment, none of them were prepared for it.

The high-strength bulletproof glass window on one side of the office shattered like paper paste with a "clang" sound. An afterimage rushed out of the window, lifted Bruce up without saying a word, and slammed his head against the wall inside the office, leaving a hole in the wall.

Seeing the person clearly, Roy couldn't help but exclaim, "Wonder Woman!? (To be continued.) )
