Tap, tap, tap.
In the silent and spacious corridor, footsteps echoed, brisk and powerful.
Guards stood tall and firm like pines on both sides, all dressed in black uniforms, tightly gripping shiny assault rifles.
The gun barrels reflected a cold metallic sheen under the light, exuding an intimidating aura.
The Guard Captain swiftly walked through with agile steps.
They wore vigilant expressions, their gazes unwavering, demonstrating the composure and skill honed in numerous battles.
At the end of the corridor is an office occupying a corner of the entire floor.
The Guard Captain slowed his pace a few meters before the door.
He first tidied his uniform, then gently extended his hand and pushed open the door.
What came into view was a gigantic surveillance screen occupying the entire wall.
The screen emitted a faint blue glow, casting a cool tone over everything in the room.
On it, the real-time image of a heavily guarded manor was clearly displayed.
