in a huge, airtight metal container.

The green, corrosive liquid poured endlessly into the jar, past the scarlet bat mark on Roy's chest. His armor reacted violently with the liquid of unknown composition, and every part of his body let out a low "sizzle" sound, and the outer layer had begun to peel off. A strange green smoke rose and quickly filled the entire confined space, as if with a hot temperature.

The armor is still holding up for the time being, but it's only a matter of time before it gets soaked.

The water level continued to rise, and Roy certainly wasn't going to sit back and die inside. He put on a mask to breathe deep and cover his chin, and pulled out a new gadget he had brought from Wayne Tech.

A cylindrical device that is so small that it fits between the fingers.

"Clean the engine wind tunnel, 750 pounds of impact." He commanded.

"Confined space, too much pressure. will cause damage to the user"

"Still execute." Without hesitation, Roy gave the order, clipped the thing to his fingertips, and plunged headlong into the liquid himself.

The scanner in the helmet quickly analyzed and scanned the composition of the liquid, and the results were quickly fed back to the screen in front of him, 11% sodium hydroxide, 34% sulfuric acid, 5% chromium solution, zinc sulfide, and a little bit of copper, which is why it emits green light.

If Bruce was here, he would be very familiar with this recipe, because he had studied the solvent a thousand times, and sometimes he would even take out the old materials and review them again when he couldn't sleep in the afternoon. Years ago, a guy wearing a red hood stumbled and fell into such a jar of solution while being chased by Batman, and it was this coincidental formula that created the Joker.

But even after all the research, Batman still hasn't fully figured out why the Joker was born.

Alfred once said that Lord Bruce always felt that he was missing something important, an important ingredient in shaping the Joker, and he often stared at the screen until his eyes were blurry, and his eyes reflected on the screen.

And then still nothing.

The small cylindrical device began to frantically pump air out of the liquid, the dead liquid being stirred into a cloud, and countless small bubbles of green fluorescence rushed towards the liquid in desperation, a pale yellow glow brewing at the bottom of the cylinder.

"Gurrah!"

With a loud bang, the sealed can was blasted open from the inside by a strong impact, half of the iron sheet flew into the air, and a huge green mist leaked out of it.

The shock wave caused the mixed liquid to rush out like a tidal wave, and Roy was like a leaf wrapped in the middle, and under the action of inertia, he broke away from the liquid and flew in an arc for several meters before falling to the ground, and the shoulders that landed smashed the steel plates of the metal aisle into depressions.

The uniform was torn all over his body, and the demonic fiery bat on his chest had also broken its wings at this time, and the wings were partially broken, and there was thick green smoke on its back, leaving the scorching temperature.

It wasn't until now that he had been led by the clown into a factory along the sewer pipe. This pool filled with chemical mixtures is in this factory.

"Well done! I knew you wouldn't be able to play it that easy! The clown's voice echoed through the factory, "You'll think it's time to talk to the script director -- your Uncle J and me -- face to face, no, no, it's not time yet." Go ahead and you'll find your rewards for clearing the level, so save the intimate conversations between us until next time! After all, your small team still has a bunch of messes waiting for you to clean up haha! That's it, bye-bye! ”

He seems to leave a flying kiss at the end, and then the broadcast ends there.

Roy frowned and tried to contact the rest of the party through the helmet, but the headset seemed to be broken along with some other features in the helmet.

Although the clown said that this is the end of the day, it is a clown after all, and what he says cannot be easily believed. So Roy remained alert and cautiously walked down the metal aisle.

Then, he finds what the Joker calls a "clearance reward" - Bruce, dressed in a suit and covered in mud, at the other end of the room, his hands dangling, unconscious.

It looks like Bruce Wayne was raided by the Mudmask on his way to another public event, and then he was brought here.

Roy jumped down the hallway, walked briskly across the room to Bruce's side, and lowered him.

Bruce coughed violently twice before waking up.

"Are you alright?" Roy asked, "Can you still go?" ”

Before Bruce could answer, there was a crisp "thud" behind the two of them, the wall was torn open like a piece of paper, and the mud-faced man rushed out from behind the wall like a torrent of hands, carrying Roy towards the empty metal pool on one side.

"Bang!"

Roy was slammed into the outer edge of the chemistry pool by the clay, and the outer wall was slightly smashed. The Clayface's entire body chased after him as if following the pull of his hand, condensing in the shape of a monstrous monster in front of Roy, shouting, "Last turn, Winged Knight!" And this round I will win! ”

"I disagree." Roy said as he opened his hand to the dirty face of the clay man, and a pale blue mist of liquid "hissed" from the hidden air holes in the lower part of the glove.

"Ahh

The mud-faced man let go of his hand with a scream, and his whole face softened like waterlogged mud.

The main ingredient is a solvent of hydrogen fluoride, and after studying the chemicals that created the clay face man and the clay composition of the clay man's body, the solvent tailored for him can dilute the body composition of the clay face and achieve the dilution effect to a certain extent.

"Roar!"

With a roar of rage, the Clayface's other hand, which had not been sprayed by the solvent, turned into a large, spiky hammer and fell heavily.

Roy rolled to the side, the sledgehammer crashing through the steel canister and the wind blowing through his head.

The clayface man's movements froze slightly, and Roy took the opportunity to quickly turn around in a half-crouch, and the freezing grenade came out of his hand.

The frost was released with the explosion, spreading along the mud-faced man's arm towards his body.

But it seems that this trick has been used on him too many times, and the mud-faced man is already very familiar with this trick. He let out a loud shout, and countless clay spikes grew out of his arms in all directions, piercing the ice crystals one after another with a "snap", and the ice crystals were pierced in an instant.

Well, it looks like the icing trick won't work, so I'll have to think of something new.

But that's something that I'm going to think about after today.

Unexpectedly, the clay man broke free of the freeze so quickly, and Roy was caught off guard by his slap on the ground.

"Got you!" The Clayface shouted, "It's game time!" It's mealtime! ”

Roy's chest was not breathing, but he still gritted his teeth and said, "I'm afraid there are still people who have different opinions." ”

Before he could finish speaking, the pale green liquid soaked from the clay-faced man's head, and the clay-faced man's body once again could not be maintained to the side, and he struggled to lie on the ground and gasp.

Bruce stepped forward in the mud and held out his hand to Roy, "You look like you need help." (To be continued.) )
