"Generate a high-resolution image featuring a ‘First Energy Gun’. The gun should have a sleek, futuristic design with a metallic silver finish. It should be handheld, about 12 inches long, with a glowing blue energy core in the center. The handle should have ergonomic grips, and the barrel should be slightly tapered with intricate patterns engraved. The scene should depict the gun on a display stand in a high-tech laboratory with a dark, ambient background."
