Alien invasion? Luckily, I'm Superman.

Mariana Trench, below Atlantis.

The pressure of the deep sea was like an invisible giant hand, squeezing the armor of Deathstroke. Deathstroke made a dull metallic scraping sound as he swam, tilting his head to look at the strange and grotesque sea creatures around him.

He couldn't help but speak, his tone inappropriately relaxed, like a goofball, perhaps influenced by his brother Deadpool: "Humans call fish-men... mermaids? That's what they call them?"

"Once I enter the deepest part of Atlantis, I may be burdened with the sin of destroying the entire Atlantis."

Aquaman Arthur said irritably, the tip of his trident emitting a faint blue light in the darkness, illuminating the outline of an ancient ruin ahead. His voice was subdued, clearly indicating that the ancient legends of Atlantis deeply troubled him.

He paused, then glared at Deathstroke. "So shut up and swim."

Deathstroke grunted, offering no rebuttal.

Interstellar sector 2682, Polaris system.

Hal Jordan, the Green Lantern, used his ring to create a green protective shield, encasing himself, Mr. Excellence, and the cracked rubber man's egg within.

The shield glided silently through space like a green meteor. Hal accelerated, his gaze sweeping across the empty star field ahead, a hint of doubt in his voice: "No offense intended, but I've worked here before. There's nothing at these coordinates. Senagan isn't here."

"Sennagan is right here." Mr. Excellence squatted at the bottom of the protective shield, pressing his fingers on the eggshell and feeling its vibrations.

His voice was steady: "The planet you were familiar with in the past was just an outpost for them. We will be heading to the hidden heart of the Empire, a place that no one has set foot on before."

Hal frowned slightly, but without asking any further questions, the protective shield accelerated again, rushing towards the depths of that seemingly empty star field.

The Belia Desert.

Hot winds whipped sand against their faces as the harpy Kendra helped the unconscious Night Master out of the portal, her steps unsteady.

Wonder Woman Diana quickly went to meet him, her gaze falling on Master Darkness, and asked, "Kendra, why are you carrying Master Darkness? Why is he unconscious?"

"Su Mo and Deathstroke knocked him unconscious." Kendra lifted the Dark Master's body slightly, his tone complex, "because the Dark Master wanted to cover our retreat."

Doctor Fate walked up from behind, his steps unsteady, his voice tinged with obvious fatigue: "Well, that's good, as long as Master Dark Night survives."

Teleporting so many people at once consumed too much of his magical energy, leaving his face as pale as paper beneath his helmet.

Kendra suddenly froze, his gaze sweeping rapidly across the crowd, his expression changing: "Wait, where's Popo? Wasn't Popo with us?"

"Don't worry about Popo, I believe he'll be alright." Wonder Woman raised her hand, pointing to an ancient building that stood out starkly in the distance, its stone pillars casting long shadows in the setting sun. "The Rock of Eternity is over there. Let's hurry over there."

Kendra bit his lip, slung the Dark Master over his shoulder, and followed Wonder Woman toward the building.

Lonely Fortress.

Superman's Antarctic base stands silently amidst the ice and snow.

Su Mo, Superman, Steel Man, and The Flash stood beneath a towering antenna tower, its metallic surface reflecting a cold, white light.

"My God! Superman, please tell me, this isn't the antenna tower that the Anti-Monitor used!" Colossus exclaimed, looking up at the tower.

"This is it." Superman walked to the base and placed his hand on it. "Batman hid it here to study and manage the energy of the multiverse."

"Management?" the Flash complained. "This place is about to explode from the dark energy!"

"That's why we're here, Flash." Superman turned his head, his gaze steady. "I realized that the coordinates of the Dark Multiverse aren't far from the Phantom Zone."

"Does this mean the Phantom Zone might be the membrane separating our world from the Dark Multiverse?" The Flash scratched his head.

Su Mo listened thoughtfully. So the barrier that the anti-monitor broke through before was the Phantom Zone?

"Su Mo, didn't you say this was a trap?" Superman turned to Su Mo and asked, "So what's your plan?"

Su Mo recalled the original plot: After Superman entered the trap, Batman erupted, fought three Supermen from the Dark Universe alone, and then took Superman away. Later, they were saved by Sandman.

He said, "Then I'll contact Sandman and have him take us away after we rescue Batman."

After saying that, Su Mo closed her eyes and her consciousness sank into a dream.

Superman didn't interrupt him, turning to the Flash and Colossus, speaking rapidly: "If we overcharge the Antenna Tower with the Speed ​​Force, and then use the Phantom Zone Generator to open a portal, the connection between Colossus and N-Metal might create a bridge to the Dark Multiverse... and Batman."

Su Mo opened her eyes: "All done."

He had just dreamt of the incarnation of the Sandman, Daniel, and the Sandman granted his request.

"Let's get started now." Superman clenched his fist.

Su Mo put her hand on Superman's shoulder, applying slight pressure with her palm: "Ready?"

The Flash took a deep breath, pushed off the ground with both legs, and transformed into a golden-red lightning bolt, running rapidly around the antenna tower.

The Speed ​​Force's current exploded from his body and surged into the tower, causing the tower's metal plates to glow and hum. Colossus placed his hands on the tower walls and began to manipulate the tower.

The illusion generator in Superman's hand lit up with a blue light, and he opened the passage to the illusion zone, where a dark light curtain opened in front of them.

Instantly, Superman was enveloped in golden light, and he rushed in with Su Mo.

The black connections between the N metals are visible to the naked eye in the void of the phantom zone, like a winding black river.

Superman sped forward along the connection, leaving a thick golden trail behind him. Su Mo gripped his shoulders tightly, being carried through a bizarre and fantastical space.

Superman made contact with the membrane between the Phantom Zone and the Dark Multiverse, broke through it, and rushed inside.

Before my eyes was a dark red void, with a huge cosmic tuning fork standing in the center. It was densely covered with all kinds of superheroes and villains, who had been corrupted by dark energy and turned into dried-up corpses with empty eyes and stiff limbs.

As soon as Superman and Su Mo appeared, the mutant Supermen resembling dried corpses immediately surged in from all directions, baring their teeth and claws, and letting out silent roars.

Su Mo's pupils contracted as the power of the Dark Dimension erupted from his body. A dark purple energy tide exploded outwards from him, blasting away the mutant Supermen. He shouted, "Superman, quick, grab Batman!"

Superman gritted his teeth, enduring the dark lightning generated by superheroes or villains on the cosmic tuning fork. The lightning exploded into blue arcs on his skin, but he did not slow down.

He flew to the center of the tuning fork and grabbed Batman, who was entangled in chains. Batman's suit was tattered and he was emaciated. He struggled to open his eyes.

"Superman, didn't I tell you not to come any closer?"

"Daniel!" Su Mo shouted.

The surrounding mutant superheroes pounced on them again.

Su Mo took out a piece of kryptonite that was covered in the black liquid of pudding from his pocket. The liquid receded, and a green light shone in the darkness.

He stabbed the kryptonite at the nearest mutant Superman. The Superman's skin began to burn the moment it touched the kryptonite, and he let out a piercing scream. The other mutant Supermen instinctively backed away, their faces showing fear.

A white lightning bolt descended from the sky, enveloping Su Mo, Superman, and Batman like a pillar of light, as the power of Sandman pulled them out of the darkness.

The injured mutant superheroes missed their target, angrily waving their arms in the void, but could only watch helplessly as the white light dissipated.

A flash of white light, and Su Mo and the other two vanished without a trace, leaving only the bound, dried-up corpses on the cosmic tuning fork and the enraged mutant superman in the darkness.
