Produce a realistic, highly detailed, full-body image of a male character with blond spiky hair and round glasses, named Cang Ji. He should have a scholarly yet adventurous look, wearing a long, gray coat over a green ensemble with utility belts and straps. Include mechanical arms or tools on his back, suggesting a steampunk aesthetic. His stance should exude intelligence and curiosity. Place him against a futuristic urban backdrop with skyscrapers, neon lights, and a technologically advanced atmosphere.
