Mysterious Shadow

The laboratory's fluorescent lights droned irritably overhead, as if mocking Li's futile efforts. Helen Cho's opposition had struck his plan to traverse the universe like a heavy hammer.

For three days and nights straight, Li had locked himself in the underground laboratory. His bloodshot eyes remained fixed on the formulas Helen Cho had covered in red Xs across the whiteboard. The loose strands of hair on his forehead had long been soaked with sweat, clinging tightly to his pale skin. His fingers unconsciously rubbed the marker, leaving dark streaks behind, as though giving form to the anxiety within him.

Gwen silently reassembled the damaged equipment nearby. The clinking of metal parts was especially clear in the quiet laboratory, every sound seeming to strike at everyone's taut nerves. From time to time, she looked up at Li, her eyes full of concern, yet she did not know how to comfort him. Wanda, meanwhile, curled up in a chair in the corner. Scarlet Magic flickered around her, brightening and dimming like her wavering mood. She tried to use magic to sense the hidden energy fluctuations, but every attempt was futile. Frustration made her shoulders sag lower and lower.

"This can't go on." On the morning of the fourth day, Li finally raised his head. Though his eyes were still bloodshot, determination had rekindled within them. He took a deep breath, forced his exhausted body onward, and walked to the computer, quickly pulling up all available information on magic and energy. As the keyboard clattered, the screen instantly filled with dense data and charts, like a sea of numbers. "Aunt Helen Cho said we lack theoretical support, so we'll start with known magical incidents and rebuild the model."

Gwen's eyes lit up. She immediately set down her tools, moved to the computer, and began filtering the data. Her fingers danced rapidly across the keyboard as if playing an impassioned melody. "When we fought Amora last time, there was an abnormal energy spike in her magic circle. We overlooked the data because of the chaos of the battle. Maybe this is our breakthrough." Wanda also rose and slowly approached the screen. Scarlet Magic gathered at her fingertips, and with her movements, the data charts began floating and rearranging in midair. Brilliant magical light intertwined with cold numbers. "I can feel a pattern in that energy. It's just hidden beneath a layer of mist. As long as we find a way to blow the mist away..."

Just as the three of them focused on their research, the laboratory temperature suddenly plummeted. Cold seeped through their pores and into their bones. The fluorescent lights buzzed overhead, their glow flickering as strange shadows spread across the room.

Wanda's Scarlet Magic surged out of control, sweeping the draft papers from the table into the air. The sheets flew wildly about like fallen leaves ravaged by a gale. She abruptly clutched her temples, veins bulging at her forehead, her face twisted in pain. "Something... something is calling to me." Before her words had faded, the laboratory's glass curtain wall exploded with a thunderous crash. Yet no shards scattered. In their place came a flowing golden mist, seeming to contain the galaxies of the entire universe within it—dazzling and mysterious.

An old man in a plain white robe strolled out of the mist. Every step he took seemed to land in the cracks of time and space. His outline looked as though it had been washed in ink, sometimes clear, sometimes illusory. Gwen swiftly grabbed an electric stunner from nearby and gripped it tightly in both hands, her gaze wary. But when she pulled the trigger, she discovered that the device completely failed within three meters of him, as if sealed by some mysterious force. Li's Protective Suit automatically activated its attack system, intelligent material flowing across his body, yet it fell into an eerie silence at the very instant it was about to strike. Li's heartbeat suddenly quickened, and cold sweat formed across his back.

"Young Stark, why are you so obsessed with the unknown?" The old man's voice seemed to come from all directions, yet it also seemed to echo directly within Li's heart. It was deep and distant, carrying the weariness of one who had seen through all things in the world. With a casual wave of his hand, a gentle light flashed. The rejected formulas Helen Cho had written reorganized in midair, blossoming into quantum geometric structures Li had never seen before. Those intricate shapes and symbols seemed to hold the universe's ultimate secrets. "Power is never gained through brute force."

Li stepped forward. His Protective Suit gave off a faint hum, revealing its owner's unrest. He suppressed his shock and stared firmly at the old man. "Do you know how to open a passage between universes?" His voice trembled slightly, filled with anticipation and unease.

The old man did not answer directly. Instead, he slowly approached, every step sending ripples through the air. When his withered yet warm palm pressed against Li's shoulder, Li's consciousness seemed to be yanked into a brilliant sea of stars. Countless universes flashed before his eyes. He saw intersecting dimensional rifts, gleaming with dangerous yet alluring light; he saw mysterious energy veins hidden in the void, like the universe's blood vessels carrying unknown power; and he saw a pair of faint, indistinct eyes overlooking everything, their gaze seeming able to see through his soul. When his consciousness returned, a trace of light from the old man's fingertip sank into Li's palm. "The true key lies between reality and illusion. When you no longer obsess over 'opening' it, the passage will reveal itself." The old man's words were like an ancient incantation, echoing endlessly in Li's mind.

Wanda suddenly staggered and dropped to one knee. Scarlet Magic wrapped around the hem of the old man's robe like vines, its glow contrasting with his plain white robes to form a strange sight. The old man nodded at her, his eyes filled with compassion. "Daughter of chaos, do not let power blind your eyes. Balance exists within contradiction." Then he looked at Gwen. The laboratory equipment suddenly emitted a resonant hum, and the indicator lights on every device flashed wildly. "Seeker of technology's light, do not let reason become your shackles."

Gwen stared at the reorganized formulas, her eyes wide as she sucked in a breath. "This is... coding beyond the laws of physics? How is that possible...?" Her voice was full of disbelief. Her hands trembled slightly as she tried to touch the formulas floating in the air, only to stop just before reaching them.

"The truth of the universe has never been something formulas can define." The old man's form began to dissipate, while golden mist flowed through the laboratory like a dreamlike vortex. "When Hydra's shadow intertwines with Amora's mist, remember— the answer is not far away, but among yourselves." As his final word faded, Li discovered a string of encrypted runes appearing across his retina. The runes gave off a faint glow. The Protective Suit's nanomaterials automatically began analyzing them, yet they could never fully decipher them.

Gwen quickly entered the runes into the computer, and the analysis results drained all color from her face. Her fingers gripped the edge of the table tightly, her knuckles whitening from the force. "These messages are warning us that an existence beyond dimensions is trying to descend through the passage. If we act rashly... the consequences will be unimaginable."

Li clenched his palm. That trace of light still radiated faint heat, while an unfamiliar yet powerful force flowed through his body. He could clearly sense every current of energy in the laboratory. The fluctuations of Wanda's magic were like warm flames, while the sound of electricity running through Gwen's equipment was like a tiny stream, all echoing in his mind as clear signals. "Maybe we've been wrong all along," Li murmured as he stared at the light in his palm, realization flashing in his eyes. "We shouldn't be looking for a way to open the passage. We need to become the passage itself." He looked at his two companions, an unprecedented light shining in his gaze. "But before that, we need to find out exactly what Hydra and Amora are planning."

At that moment, the laboratory alarm suddenly blared, its piercing sound shattering the brief silence. Natasha crashed through the window. Smoke still rose from the shoulder armor of her Black Widow suit, and she bore the marks of battle. Her wary gaze swept across the room before settling on the golden mist lingering in the air. Her brow furrowed almost imperceptibly. "Hydra is making a major move. Their activity deep beneath New York has intensified, and Amora seems to be involved as well." She paused, a trace of confusion flashing through her eyes. "Looks like things haven't been peaceful here either."

Li, Gwen, and Wanda exchanged glances. The three of them had already made their decision. A confrontation beneath New York was about to begin, and the power and riddle left behind by the old man would become the key to uncovering the truth.
