The toxin spread rapidly along the air, burrowing into everyone's mouth and nose, and the street that had just been in full swing fell silent for a moment.

The Joker lifted the collapsed Batman with one hand and said loudly: "Wait, wait, wait!" I almost forgot! There's one last thing before you go, I'm going to send you on your way with a super big joke at the end! Ha! What do you want? The bat antidote behind me? To tell you the truth, I infected it a long time ago! Ha ha! Yes, it will never be pumped out! But but but, don't close your eyes and laugh here, hehe! Look at it, Batboy! ”

He took out a thin piece of mobile phone and handed it to Batman, the screen was a picture of real-time monitoring, an empty well.

"Look, Bats! There is still a remnant of the Dionysian factor! He said triumphantly, "Yes, a little stock!" But this little bit is in the Gotham underground, super deep! Walk through tunnels and junctions that turn around a thousand times! In the deepest rock bed of Gotham! Hide well, connect to the line of fire, and get ready to blow up! It's a pity you still don't know your city well enough, huh? You're just a mortal, a little boy who hasn't grown up, crying and crying because your parents left you. That's your biggest weakness as a human being! So continue to grieve, baby bat! This time, the whole world will say goodnight to you! ”

He tugged at Batman's mask with one hand, "Now, let's take a look at those cute, pitiful, lying little eyes, Bruce"

But when he ripped off the bat mask with one hand, his face changed suddenly.

"You You Are"

"I'm guessing you're talking about Dick, huh." Dick Grayson, dressed in a batsuit, chuckled.

"Nope! That's impossible! ”

The clown hurriedly threw him aside, took the detonator from his bosom, and pressed the switch.

There was no reaction in the hole in the phone video.

"No!"

1,000 feet underground.

"A thousand feet deep, Batman, and your rope should be at the end of it."

Batgirl stood by a makeshift hole in the park and said via a messenger.

"Yes, Barbara." Batman grabbed a rope and continued to fall from the deep hole, "It's coming." ”

Once his feet were on contact with the ground, Batman released a small orange ball that glowed with a bat mark. Developed by his father when he was in charge of Wayne Enterprise, it was able to automatically map and explore paths in places that resembled the bottom of a cave, and was figuratively called "Eye".

"How's the rest going?" Batman asked.

"Contact is lost, maybe the signal is intercepted or it could be worse."

Batman didn't speak again, just moved forward in silence.

Lines are buried everywhere on the surrounding rock faces, as well as explosives boxes with smiling faces painted on them. There are so many of them that it is impossible to completely dismantle them, and Batman can only temporarily jam the signal to prevent the Joker from detonating remotely, but if the Joker comes down to this cave, he can still detonate explosives.

He didn't have much time left.

The all-round stereoscopic image drawn by the "eye" points to two possible directions at a fork in the road. Batman gritted his teeth, he didn't have time to try a dead end now.

Try your luck at one random and see if you have chosen the right path?

A voice sounded from behind him: "Left." I marked the radioactive markers of the Dionysian factor intercepted from Deco, and a trace of similar radioactive markers was scanned on the left track. ”

When Batman turned around, he found the Winged Knight shining through the darkness behind him.

"What are you doing here?" Batman asked gloomily, "That's not how the plan works." ”

Roy said, "No, that's the plan from the beginning, but I didn't tell you. ”

"Go back." Batman said in a non-negotiable tone, "Just here." ”

"The clown is already on his way, and he could come in through any entrance at any time." Roy said, "You know, this time is different from the past. This time we're going to face a brand new clown that's all we're all familiar with, and you'll need a hand. Besides, he's probably getting closer and closer in the middle of our arguments, so are you going to fight with me here endlessly or work together to get the job done? ”

Batman frowned and stared at him for a moment.

Then, without saying a word, he turned and continued to walk inside, which was considered acquiescence.

What Roy didn't say was that he was here or out of a promise.

Not long ago, after defeating Mudface, Roy was stopped by Alfred at Wayne Manor as he left the Batcave one day.

"Would you like a cup of tea? Mr. Green? Alfred asked politely.

"No, thanks."

"I suggest you have a cup, I'm confident that I can't taste the tea I make anywhere else." Alfred said, "Also, I want to talk to you. ”

Roy was a little surprised, but was invited to sit down with Alfred in the study.

"Master Bruce always mentions you," said Alfred, as he placed the brewed tea in Roy's hand, "you know, it's very unusual for him. ”

"Flattered."

"But I'm curious what you think of him? What kind of person is he? ”

Roy was stunned.

"Batman?" He thought for a moment and said, "Strong, willpower like steel, and wisdom?" ”

"That's what most people probably say about Batman." Alfred sighed, "But to me, he was always that child, my child. Maybe you think it's strange for me to say that. ”

"Nope." Roy smiled, "Actually, not at all. ”

"Like all parents, we worry about our children, especially those like the old man," Alfred said. He felt like a criminal – never changed, and I found his self-sacrificing tendencies more than once. He always had no regard for his own safety, as if it were a punishment for his own actions. I knew that if this continued, sooner or later I would have to bring his body back to this cave. ”

After a moment of silence, Roy asked, "Why are you saying this to me?" ”

"Because, I hope that when that happens, someone will take care of him." Alfred said seriously.

Roy stared at the old man's weathered eyes for a long time, and then said, "I promise." ”

If there must have been a moment in Batman's life that Alfred was talking about, it is a moment like this.

That's why Roy insisted on following Batman down here – and making good on his promise.

Walking along the tunnel to the end, a large and open cavern was illuminated by a green glow in front of you.

A pool, like the Lhasalus Pool, glows brighter, only brighter and more mysterious.

"Found it." Batman whispered. (To be continued.) )
