Lingchen was originally one of the most ordinary people among all living beings - a city worker in his early twenties, crowded in the subway crowd from nine to five, with endless reports piled up at his desk, and relying on animation, novels, and movies at night to escape the boring reality. One rainy night when he was working overtime until late at night, he picked up a palm-sized black Rubik's cube in the corner of the recycling bin downstairs: the edges and corners were covered with matte silver patterns, and there were no numbers on the six sides, only flowing dark golden lines. It was warm in the tentacles and trembled gently as if it were alive. He thought it was a worthless toy, so he turned it casually, and the Rubik's Cube suddenly erupted with bright light and swept him into boundless chaos. When his consciousness returned, the Rubik's Cube was embedded in the palm of his hand, and a cold mechanical voice sounded in his mind: "The universal prop Rubik's Cube is bound successfully, and the system of traveling through the heavens is activated." Ordinary life Completely shattered, Lingchen held the key to his destiny and embarked on a journey through thousands of fantasy worlds. From passive survival to active exploration, in the world of countless intertwined lights and shadows, he searched for meaning beyond the ordinary, and there was also a hidden expectation that "maybe he can meet his true self in a certain world."
