Three doctors, including Dr. Yang, sat in a room, their hands tied behind their backs in chairs. Four clown thugs armed with submachine guns walked around several people, chatting with each other.

"I'm so glad to see the clown come out." One thug said, "I knew from the beginning that he wasn't going to be so easy to get caught in an insane asylum." He's a clown, after all, don't you say? ”

"I once offered to have Mr. J's face printed on the dollar bill." Another thug said proudly.

"The result?"

"It didn't go well."

"Hah! I knew it. ”

"No, you don't understand." The thug tried to argue, "I almost made it!" It's all Batman! If it weren't for him"

At the mention of Batman, several people sighed.

"Alas, I heard that the clown has made some very powerful medicine this time, which can make people very powerful, as if they have superpowers." One humanity.

"Is there such a thing?" The other raised an eyebrow and asked, "Then if he allocates a little bit to each of us, won't we all have to be afraid of Batman?" ”

They were chatting vigorously when a piece of the roof exploded. Batman spreads his cloak and jumps into the house gorgeously and grandly.

"Batman!"

A few panicked thugs shouted, but they only had enough time to shout. Batman is extremely agile, and when he jumps, he just falls on top of a person's head, and after getting this person, he quickly pounces on the next target, and the eagle pounces on his head to the ground, and then rolls in front of the third person and knocks it down, and slams his elbow on the door, and the moment he collects, the batman is thrown at the fourth person, and a dart in the head shocks the fourth guy and faints immediately.

Although several thugs tried to turn their guns against him, the four of them were solved in three or two before they could aim at the target, and the three hostages were stunned.

Batman walked forward quickly, and in order to loosen his ties, he stared at the female doctor and asked, "Dr. Pennylou Young?" ”

She nodded, "I am." ”

Batman said, "The other two go first, go to the safe room and lock the door, tonight will be over soon." Dr. Yang, you have to stay, we have to talk. ”

The other two glanced at each other and fled quickly.

Dr. Yang said hurriedly, "I know what you're going to ask me, but it's too late. Joker, he already has the recipe for Titan Venom, and after he was sent to Arkham Asylum, he began to force me to develop this venom for him every day."

"Do you have a backup of the recipe?" Batman asked, "If we can get a backup, we can produce an antidote from recipes." ”

Dr. Yang shook his head, but said, "No, but it's not necessary." I've written the recipe for the antidote, and it's on the bookshelf in my study. ”

Batman pressed his headphones and said, "Oracle, do you hear that?" ”

Barbara responded: "I heard you, I marked the location on the map of the Winged Knight, and he will go over to get the recipe soon." ”

Dr. Yang added, "And I have successfully produced a trial antidote in the past two days."

"Where?" Batman asked.

"Right here."

Dr. Yang walked briskly to the deepest wall of the room and said, "To produce the antidote, you need to use a spore produced by the Poison Ivy Woman, which can be collected from her plants. Luckily, my position in Arkham gave me many opportunities to take liquid samples from her plants while she was unprepared."

As she spoke, she came to the vault on the wall. She entered a code, then turned to unlock the vault door, pulling the heavy metal door open.

At this time, Batman realized that something was wrong, and shouted while rushing forward: "Doctor! Get down! ”

However, it was already too late. The high explosives were activated the moment the vault door was pulled open, and flames roared out of the vault, engulfing Dr. Peneloe Young in flames before he even had a chance to scream. The powerful impact knocked Batman, who was trying to rush up, to the ground, and rolled two or three times before stopping.

Ignoring the slight concussion, Batman slammed his fist to the ground, and the wall was already a pile of rubble. There is no doubt that the antidote stored inside has also been shattered.

The clown's face flashed on the TV set hanging from the roof, and he laughed like a child who had succeeded in a prank, exclaiming, "Hahaha! You don't really think I'm keeping this doctor just in case, do you? You know what? In fact, she is useless for a long time! Her last bit of use is actually a trap to lure you into the bait, and then you cooperate to make her burn out the last meaning of life, how touching! ”

Batman gritted his teeth: "Joker"

The ceiling suddenly collapsed, and a pile of masonry and chandeliers crashed down on Batman's head, and a behemoth appeared to be clustered in the center of the rubble. Batman reacted quickly and rolled to the side, narrowly avoiding it. I saw a large man slam down where he had just stood, stomping on the floor and collapsing.

"Hahahaha! Did I just forget to introduce the guest of this play? "Let us have the honor of introducing the guard of Arkham Asylum, Mr. Dyson Weris!" ”

As if he had really heard someone call his name, the big man really opened his mouth and threw his head back and yelled.

Batman was taken aback: "Weris? Is that you? ”

He knew many of Arkham's guards, including Dyson Verris, who had the misfortune of being chosen by the Joker as a test subject for Titan Venom.

There was no response, and Verris had gone completely berserk, holding his hands into a giant hammer and slamming down with the momentum of Tarzan. Batman lunged to the side, followed by a tumble to dodge.

But before he could stand on his feet, the wall behind him shattered, and a huge hand reached out from it, grabbed him by the waist and lifted him up. Another Titan smashed through the wall and walked in.

"Hahaha! When people get old, their memory is not as good as before, and they forgot to introduce it! "Now we have the honor of introducing our guest, Mr. David Paskin, who is also a Arkham guard!" David, say hello to our old bat. ”

"Roar!" The monster named David roared in response to the Joker's words.

Roy made his way along Arkham Island's sewer system.

"I don't want to wash your uniform when I come back today." Barbara said, "I guess you must smell bad right now." ”

"You said you walked down the sewer system."

"In order to avoid the madmen running around on the road, and to get to the location where Dean Quincy Sharp is trapped as fast as possible, this is already the fastest route." Barbara said, pausing, adding, "But it doesn't change the fact that it stinks, maybe this time you better wash it yourself." ”

Roy stopped suddenly.

"What's wrong?" Barbara asked.

"Be quiet for a while, there's a sound." Roy replied.

From time to time, a cool breeze blows through the sewer pipes, stirring the dirty water surface and making a gurgling sound similar to that of a stream.

Barbara listened intently, too, but unfortunately the sound didn't seem noticeable, at least not through the headphones. Puzzled, she asked, "Did you hear me wrong?" ”

Roy ignored it, cautiously groping his way forward to take two steps as he looked left and right.

The reason why the bat family likes to hide in the dark is that they like to put themselves in the first place. Once the opponent is in a hidden position and we are exposed to the light, it is already equivalent to losing half.

Just like it is now.

As if something was piercing the water, a burly figure burst out from the stream of water at Roy's feet, letting out a roar that seemed to burst his eardrums. He had green skin, and the scales covered his body as if a piece of armor covered his body. His teeth were sharp, his claws were sharp, and his green pupils glowed with a faint glow.

It's like, a crocodile.

He is also one of Batman's old rivals, and he is a killer crocodile with excellent water resistance, strong scales and strong enough to resist bullets, and has a lot of brute strength!

But all of this was seen by Barbara by twisting the camera behind her with Roy's head for a split second.

Roy didn't have time to see the face of this terrible enemy, because he had been pressed to the back of his head by the other party at this time, and he was slammed face down into the water.
