On the top floor of the tallest building in Shanghai, a young man stood alone, gazing out at the sprawling city below. Shanghai, the richest city in China and the most expensive in the world, was at his feet—literally and figuratively. The owner of this towering structure needed no introduction; he was undeniably one of the world's top billionaires.

"Just as I thought, no supernatural powers exist in this world," he muttered to himself, his voice tinged with resignation.

The young man, with a face as striking as any male lead from a Korean drama, looked to be in his mid-20s. Standing behind a glass window, he observed the teeming masses on the streets below with cold, indifferent eyes. His expression was calm, almost serene, but his mind was a whirl of thoughts.

"Have you decided?" 

The sudden, mechanical voice broke the silence, echoing through the vast office. The voice was cold, emotionless, and seemed to come from nowhere.

A black-haired young man, one hand casually in his pocket and a cigarette in the other, nodded. "I've decided. I accept your offer," Gu Fanyu replied, his voice steady.

To his right, a floating ball of light hovered, the source of the disembodied voice. It had appeared three days ago, disrupting the young billionaire's routine with an offer that seemed too fantastical to believe.

Three days earlier, as he relaxed in his office, this strange light had materialized before him, introducing itself as a System from a boundless universe. The System offered to make Gu Fanyu its host, promising him real superpowers. But there was a catch—these powers could only be attained in another world, for Earth, as it stood, was devoid of any supernatural energy.

Initially, Gu Fanyu's sharp mind dismissed the System's claims as a trick, perhaps orchestrated by some shadowy organization. After all, the world's elite knew well of his obsession with the supernatural. For five long years, he had poured billions into searching for evidence of such powers on Earth, only to be met with disappointment. Ancient legends, ghost stories, and myths were all he had found—nothing concrete, nothing real.

Yet, despite his skepticism, something deep within told him that this System was genuine. To test its authenticity, he called upon his employees, asking if they could see or hear the System. None could. He even checked his office's surveillance footage, but the System remained invisible to the cameras. It seemed the System was real—if only to him.

"Even if there's a chance you're lying to me, or that you want to take over my body… Life is a gamble. It's more thrilling when the stakes are high, haha!" Gu Fanyu's laughter rang out, full of reckless abandon.

His eyes were eerily calm, like the surface of a still lake. It was a gaze that spoke of a man who had stared into the abyss of life and death and found them lacking. It was hard to believe this sense of detachment belonged to someone not yet thirty.

Wealth, fame, authority—these were all meaningless to him. They were mere illusions of power. In the end, no matter how much one had, all it took was a single bullet to end it. That was the harsh reality.

True power, however, was different. True power could make one invincible, beyond the reach of any threat. And now, the opportunity to obtain such power was standing before him. How could he not seize it?

Only Gu Fanyu knew the true reason behind his meteoric rise to the top of the business world. It was not wealth he sought, but the resources and capital needed to scour the Earth for the supernatural powers he so desperately craved.

"You've made the right decision and will not regret it," the System affirmed in its cold, robotic tone.

Gu Fanyu smirked, his voice calm as he replied, "I hope so. Now tell me, what exactly are you? And how will you help me obtain these superpowers?"
