Sci-Fi Apocalyptic Soldier with Pistol and Gas Mask in Biohazard Scene

Description

A man in black tactical gear stands before an abandoned stone wall, wearing a transparent protective goggle and a gas mask. He holds a pistol in one hand and rests the other on the holster, maintaining a calm posture. His black tactical vest is covered with pockets, knee pads and tactical pants enhance protection, and dark military boots step on the ground covered with dead leaves. The mottled stone wall and dim environment in the background create a terrifying sci-fi atmosphere like a virus infection or biohazard crisis, as if he is a warrior on a mission in the apocalypse. The details of the equipment highlight the military style and tension, and the dark tones and desolate scene strengthen the sense of depression after the disaster.
