American comic book: After mastering resurrection, I became incredibly popular.

At the same time, Tim Drake's voice cut into Batman's communication channel, interrupting Batman's conversation with Wang Baixi. The sound of sirens and his own footsteps were also recorded.

His situation was also a bit urgent, because Tim had just heard Barbara fall to the ground.

“Bruce, Cassandra and I are at the back entrance of the aquarium. There's a line of police cars blocking the main entrance; Chief Gordon has closed the entire street. Barbara's GPS is still on in the main exhibit hall; I've been calling her for three minutes, but she hasn't responded even once.”

Batman's voice came through the communicator, "Report your location every thirty seconds after you go in."

"Got it." Tim glanced back at Cassandra and gestured with his chin toward the fire escape at the back door.

The two climbed onto the roof one after the other and found the vent that Barbara had pried open earlier.

Tim went in first, with Cassandra close behind. A sweet smell wafted through the ventilation ducts, and Tim's mask's filtration system immediately triggered a toxic gas warning.

"Oh no! There's nitrous oxide residue in the pipes!" Tim reported over the communication channel.

But Barbara had already been inside for at least ten minutes!

"Hurry up," Batman said.

"Yes."

Tim and Cassandra crawled along the pipes on their hands and feet until they reached the mezzanine above the main exhibition hall.

The animals in the tank had all sunk to the bottom, their mouths agape, but their bodies remained motionless.

Tim spotted Barbara immediately.

She lay curled up in the center of the main exhibition hall, her chest still rising and falling, the long stick still clutched in her hand. Beside her lay a man wearing a plastic clown mask, but he was no longer moving.

It was clear that there were no signs of life.

Tim flipped over and jumped down from the mezzanine. After landing, he rushed to Barbara in a few steps, squatted down, and held her shoulders.

"Barbara, Barbara! Can you hear me?!"

Barbara's body was trembling. Her eyes were open, and her gaze turned to Tim's face. Suddenly, the corners of her mouth twitched upwards, creating an arc exactly like the animals in the tank.

Her muscles were twitching uncontrollably.

A chill ran down Tim's spine.

"Barbara!"

It seems she has been poisoned.

The question is, with only ten minutes, will the effect be that strong?

He grabbed Barbara's arm and draped it over his shoulder, then supported her waist with his other hand, lifting her off the ground.

"Cassandra, let's get her out of here quickly!"

Cassandra had already jumped back into the mezzanine and reached out to pull Barbara out. The two of them, one above and one below, carried Barbara out of the ventilation duct.

Barbara trembled the whole way, occasionally letting out a faint, almost inaudible laugh, but with each utterance, her face contorted in pain.

And so, Tim and Cassandra scrambled from the aquarium rooftop to the back alley. Tim lifted Barbara into the sidecar of his modified motorcycle and shouted into the comms channel:

"Bruce, we've rescued Barbara. But it seems she inhaled a lot of poison gas; she's shivering. I plan to take her straight back to the Batcave for treatment."

Before Batman could respond, Cassandra had already jumped into the back seat, while Tim twisted the accelerator and sped off toward the Batcave.

……

Half an hour later, the bat cave was completely silent, with only the sound of the heartbeat from the medical monitors.

Wang Baixi leaned against the stainless steel bench outside, his elbows propped on his knees, his eyes fixed on the floor. Zatana and Tim sat silently beside him.

Just now, Wang Baixi, Jason, and Barbara all had their blood tested, but because he was fine, he didn't have to lie in the medical room like Barbara and Jason.

After all, the [Life Reversal] was too powerful; even though Barbara had Amber Gold in her body, it couldn't help her detoxify.

At the same time, Batman walked in from the other side of the medical room, holding three freshly printed blood test reports, his eyes scanning from the first line to the last.

"How's the situation?" Wang Baixi asked immediately, noticing that Batman was still looking at the report.

“Nutrition nitrous oxide was detected in the blood of all three of you, but at different concentrations.” He placed the report on the console and pulled up a molecular structure diagram. “Barbara’s serum had the highest concentration of nitrous oxide, exceeding the critical value. Jason’s was next, and as for you… Wang Baixi, the nitrous oxide adhesion rate in your blood was so low that it was almost undetectable.”

"What do you mean?"

Is he an expert at fighting off viruses?

“First of all, this nitrous oxide is unlike anything we’ve ever seen before. Based on our initial assessment, it’s somewhat like a biological weapon that locks onto the target’s biological information in advance, and then takes effect on specific individuals very quickly.” Batman zoomed in on the molecular structure diagram. “Obviously, the three of you may all be targeted. But this is just a guess, because the criminal is dead, and we can’t get any definitive information from Bernie, the person involved, so we can’t draw any conclusions.”

“It was my fault. I should have spared them,” Wang Baixi sighed.

He's a bit too extreme.

“But how could the Joker have locked onto Barbara beforehand?” Zatana stood up, crossing her arms. “Barbara has rarely acted alone since she regained her mobility. How could the Joker have had the opportunity to collect her biological information?”

“I don’t think it’s necessary to collect it from Barbara herself,” Tim said. “If the Joker got a biological sample from Commissioner Gordon, he could probably do it too. After all, they are father and daughter, and Commissioner Gordon is in and out of the police station every day. The Joker has plenty of opportunities to get close to him. He could brush against the doorknob, touch his fingers when handing over documents, or any other way he could get what he wants.”

"Is it possible that Sheriff Gordon is also on the Joker's list?" Zatanna asked again.

“It’s hard to say, but we’ve already notified him. The tricky part is how to tell him that Barbara isn’t home,” Tim sighed.

“Yes, after all, he doesn’t know that his daughter is a masked vigilante,” Wang Baixi chimed in.

“The only thing we’re certain of is that the Joker has been preparing for this for a long time, not just in the last few days.” Batman zoomed in on the molecular structure diagram to full screen, marking several layers of interlocking structures with his finger. “This new nitrous oxide virus combines Bane’s venom, Scarecrow’s fear gas, and Poison Ivy’s plant extracts. Just combining these things together and keeping them stable will take at least a long time. The Joker has been preparing for this for a long time.”

"In other words, the three clowns started cooperating a long time ago," Wang Baixi concluded.

Tim tried to reassure everyone and ease the tension: "The entire city is now under martial law. Wayne Enterprises' medical department and the Court of Owls have jointly mobilized backup antidotes and chemical protective equipment. Learning from the Bane incident, we should be able to minimize any potential losses."

Cassandra, who had been silent all along, started signing, "We can now free up our hands to catch Laughing Man. He's definitely not out of Gotham since he escaped from the swimming pool."

“Never mind Laugher for now,” Batman said. “The most important thing right now is Barbara. Her poison has already reached a critical level, and if she doesn’t receive effective treatment soon, her brain will collapse first.”

"I'm going to check on Barbara!" Wang Baixi couldn't sit still any longer and said hurriedly.

“Let me also take a look at your medical report, Wang,” Tim said. “While you’re fine, we can’t be sure there aren’t any other injuries.”

"understood."

After saying that, Wang Baixi headed towards the medical room.

"I hope Barbara is alright." Batman's brow furrowed again after Wang Baixi went inside.

He believed in Barbara; the girl was always so strong. At least compared to Jason, he thought Barbara was better at overcoming adversity. However, Jason was, after all, a minor, unlike Barbara. But the nitrous oxide virus was now so troublesome that it was giving him a headache.

“How about…we try a low temperature?” Tim suddenly thought, and looked up at Batman.

"Low temperature?"

"Yes, we used cryogenic technology to temporarily put Barbara into a state of suspended animation, freezing the nitrous oxide virus in her body with ultra-low temperatures. Once her metabolism drops to its lowest level, the spread of the virus will also slow down. This way, we've bought ourselves enough time to study how to completely eliminate the toxin."

“This method makes sense, but how can Barbara’s body withstand it?” Zatana frowned. “Ordinary people can only last a few hours at low temperatures before cell crystallization occurs.”

"...Have you come up with a solution?"

Suddenly, Wang Baixi's voice interrupted the argument. He walked out of the medical room with his report in his hand and gently closed the door. The corners of his mouth were slightly upturned, and he looked as relaxed as ever.

Cassandra was the first to notice him. She walked up to him and asked in sign language, "Are you alright?"

"Are you talking about Jason or Barbara? They're talking right now, I didn't interrupt them. Jason seems to be doing alright, but as for Barbara... to be honest, she's a bit weak."

“I mean you,” Cassandra said, pointing to his report.

“It’s alright, it’s really alright.” Wang Baixi smiled and turned to Zatana, saying, “By the way, Zatana, you don’t need to worry about the low temperature harming Barbara’s body. Victor talked to me and he discovered that the specially made amber gold can also make the body resistant to freezing. Barbara happens to have that kind of Victor’s specially made amber gold in her spine, so it’s perfectly feasible to put her into a state of suspended animation by using low temperature.”

Batman listened for a few seconds in silence, then nodded: "Then let's use this plan."

Wang Baixi laughed and said, "Then we can catch the clown without worry, right?"

Zatana looked at him, her lips moved, but she hesitated to speak.

“Wang,” she said, “you shouldn’t laugh at times like this; it looks quite scary.”

……

After the door to the medical room closed, the discussions outside turned into a low hum.

It was less of a chat and more of a one-sided conversation between Jason and Barbara. He hadn't seen Barbara Gordon in a long time, and he hadn't been back to the Batcave or Wayne Manor in ages.

It's fair to say that his return was not pleasant. The only thing that made him happy was seeing Alfred again, who was much better than that jerk Bruce.

Besides, everyone here is a complete stranger.

Zatana? He'd seen her once or twice. Wang Baixi, Cassandra, Tim Drake—who were they? And that brat Damian—everything was irreversibly heading towards a "terrible" situation.

This is not his home; he feels out of place here.

Right now, he's sitting on the hard plastic chair next to Barbara's bed.

When was the last time he sat in this kind of chair? Maybe it was the day he woke up in the field hospital, or maybe even earlier, so early that he couldn't be bothered to recall.

Barbara lay before him, her face as pale as the sheets. Her lips trembled slightly, and Jason bet she was trapped in some disgusting hallucination or nightmare.

Jason is all too familiar with this situation; he himself hasn't fully recovered from it to this day.

“You’re amazing, Barbara.” He tried to encourage Barbara, or rather, he prayed that his voice would reach the unconscious Barbara’s ears.

"You were hurt so badly by the clown, but you didn't cower in a corner licking your wounds, you didn't blame fate, and you didn't give up. You put your uniform back on and stood before the person who hurt you again."

“I can’t do that. After I crawled out of my coffin, I received training from the League of Assassins, and even developed feelings for Talia that I shouldn’t have. Most importantly… I hired the Silent One, the Riddler, and two lunatics to work together to get revenge on Bruce in the dirtiest way possible.”

He rubbed the stubble on his chin with his palm.

"To be honest, I've always been afraid to see you guys. I'm afraid that when Bruce sees me, he'll look at me with that disappointed expression. I saw it when he was still his Robin, and it felt worse than being hit by a crowbar. I really can't stand that feeling."

"After leaving me, he found someone else to replace me, didn't he? He even tolerated an Asian man committing murder. I really don't understand, what's wrong with him? I... I only know you now, Barbara, maybe you're still... my friend?"

He paused, lowering his voice even further.

"My friend, you are stronger than me, and I have always admired you from the bottom of my heart. You will definitely get through this."

Suddenly, the door to the medical room was pushed open.

Batman walked in and closed the door behind him. The air suddenly tightened as the two grown men, one standing and one sitting, sat together.

Jason didn't look up, but he knew who had come in. He just silently moved his hand off the edge of the bed and put it back on his knee.

“I don’t think I invited you in, sir in the cloak.”

Batman didn't respond, but instead said firmly, "Come out and talk, Jason."
