The newcomer wore a combat suit of intertwined dark blue and orange-red. The peculiar color scheme made the full-coverage metal helmet look clearly divided. Despite there being no wind around, the two slender red cloth ribbons behind the person's head were fluttering.
"Whoa, it's a Deathstroke who calls himself Batman." Spider-Man couldn't help but complain upon seeing the newcomer.
Clearly, DC comics existed in this world, and as a young man, Spider-Man naturally loved such superhero comics.
Even if he was a superhero himself in real life.
"Who exactly are you, and why can you enter my world!"
Mr. Negative was on high alert; this was a mental world constructed by his supernatural power. Why would a stranger appear here!
In this world of intertwined black and white, the person who suddenly appeared said in a raspy voice that sounded like throat cancer: "Heh, for whom the bell tolls? I am Superman!"
"You just said you were Batman a second ago." Spider-Man was still complaining, but no one paid him any attention.
With the sudden appearance of an unknown entity—friend or foe—Spider-Man didn't act rashly, but Mr. Negative couldn't sit still. This was his world!
He still wanted Spider-Man to join him; how could he tolerate another person appearing here?
"The shadows are loyal to me, and I shall grant them power!"
Mr. Negative suddenly floated into the air, and the surrounding black and white energy reorganized and condensed. In an instant, a giant black-and-white demon mask appeared behind him.
Then, black-and-white firebombs suddenly shot out from the mask's eye sockets, blasting toward Spider-Man and the sudden stranger.
"I won't let you succeed in the darkness, Martin!"
Spider-Man ignored the stranger, shooting out a web to catch the bomb burning with black-and-white flames, then threw it back toward the mask with a backhand swing.
Boom—!
But the bomb exploded in mid-air, and the intertwined black and white flames instantly splashed down from high above. Having his Spider-Sense, Spider-Man avoided it with a few leaps.
On the other side, Xia Yu, standing still, ignored the firebombs thrown at him. Everything here was happening in Mr. Negative's mental world; in other words, everything here was fake.
"What a pity." Xia Yu waved his hand to brush away the firebombs about to reach him, speaking with some regret.
If all this were real, it would be a proper low-budget version of the Shadow Kingdom. Unfortunately, it was all fake.
He could also pull others into his own mental world, but everything in a mental world is ultimately fake and cannot be taken as real.
Furthermore, it was precisely because his mental power was stronger than Mr. Negative's that he could intrude. If he wanted to, he could even take over control of this mental world effortlessly.
Seeing Spider-Man still fighting that giant mask, Xia Yu shook his head. With a single thought, this world instantly froze. Mr. Negative, having lost control, fell down with a thud.
Still not knowing what had happened, Mr. Negative raised his black face in confusion, his eyes glowing with white light filled with incomprehension.
The next moment, cracks appeared in the black-and-white world, a brilliant white light flashed, and the black-and-white world vanished instantly.
The three returned to reality.
Mr. Negative was still grabbing Spider-Man's wrist, and Spider-Man had also woken up from his brief unconsciousness.
Seeing they were back in reality, Spider-Man hurriedly used his free hand to punch Mr. Negative's face, wrenching his other hand free from Mr. Negative's grip.
"Martin, you can come back to the light!"
"No!"
The punched Mr. Negative let out a roar, black and white energy erupting from his fists. Just as he was about to strike back, the entire armored vehicle he was in suddenly jerked to a halt, as if it had hit an invisible wall.
The sudden stop sent everyone in the vehicle flying due to inertia. Even Spider-Man, in the suddenness of the situation, failed to stick to the armored vehicle.
With several thuds, the people in the driver's seat were thrown out. Since the windshield was already shattered, they all fell outside the vehicle.
"Ugh, that really hurt." Spider-Man clutched his lower back, leaning against a wall as he muttered and stood up from the ground.
Mr. Negative also struggled to climb up from the ground, but he quickly thought of the Devil's Breath in the driver's seat. Just as he wanted to return to the armored vehicle, a dark blue and orange-red figure entered his sight.
That figure appeared silently, walked slowly to the side of the armored vehicle's driver's seat, and then took out a sealed box from inside.
"Devil's Breath!"
"Whoa, Deathstroke!"
The voices of Mr. Negative and Spider-Man rang out simultaneously. Hearing these two statements, Xia Yu turned his head and said seriously:
"Not Deathstroke. I am Wonder Woman."
"Changed again. Also, Wonder Woman is clearly a woman, and you are clearly a man..."
Spider-Man continued to complain, but Mr. Negative could not accept the Devil's Breath being snatched by someone else. He suddenly unleashed a beam of black-and-white energy from both hands.
But this attack didn't even touch the corner of Xia Yu's clothes before being blocked by an invisible wall. Seeing this, Mr. Negative was not discouraged, and the black-and-white energy in his hands instantly transformed into a solid longsword.
Just as he was about to attack, Xia Yu's figure suddenly vanished, then reappeared behind Mr. Negative like a ghost. Then, a hand-chop struck.
Bang!
Mr. Negative collapsed at the blow. Seeing this, Xia Yu nodded in satisfaction. As expected, hitting the head is the easiest way to cause a knockout; he wouldn't hit the neck anymore, he'd go straight for the head.
After fainting, Mr. Negative also exited his negative form, reverting to his original human appearance.
On the other side, Spider-Man, seeing Mr. Negative faint so easily, immediately gasped. If the opponent could easily deal with Martin, could he also easily deal with him?
Maybe the opponent isn't an enemy after all, Spider-Man thought somewhat optimistically, but he also knew the possibility was slim. The opponent was clearly here for the Devil's Breath.
"Mr. Deathstroke, could you..."
"Not Deathstroke. I am..."
"Fine, fine, I get it. You're The Flash, Green Lantern, Cyborg—anything but Deathstroke, right?"
Spider-Man couldn't help but interrupt Xia Yu. Hearing this, Xia Yu nodded.
Seeing the other party actually nod, Spider-Man wanted to complain even more, but he was a mature Spider-Man and could suppress his urge to speak.
"Mr. Flash, could you..."
"No." Before Spider-Man could finish, Xia Yu reached out a hand to block him. "The Devil's Breath is my goal for this trip. I can't let you have it, little bug."
"Hey, spiders aren't bugs, they're arachnids!" After reflexively retorting, Spider-Man aimed his wrist at Xia Yu. "Then I'm sorry. By the way, your armor is pretty cool."
But before he could fire the webbing from his web-shooters, the whirring of a helicopter suddenly came from above, and a beautiful woman with short silver hair suddenly dropped from the helicopter on a rope.
Falling with her were other mercenaries in combat suits. The silver-haired woman first scanned the surrounding situation roughly, then immediately drew her dual pistols and aimed them at Xia Yu.
"Hand over the serum."
"Aren't you going to ask who I am?" Looking at Silver Sable, who was even colder and more elegant than in the game, Xia Yu spoke unhurriedly.
"Hmph." Silver Sable gave a cold snort and actually fired at Xia Yu's shoulder without hesitation.
