"Bang! Bang! Bang!"
The door was slammed on heavily.
"Open the door!"
Under the dark muzzles of the guns, the leading secret service agent said in a low tone.
Pairs of eyes stared at the scene before them.
Behind him, above the elevator, the red numbers kept jumping. With a ding, the elevator doors opened.
The middle-aged man in the gray uniform walked to the door with a toolbox.
He took out his tools.
The middle-aged man was suddenly ducked down. Behind the door, footsteps echoed, and the anti-theft dark red door behind the metal body was pulled open a crack. A normal-looking young man poked his head out from the crack.
When he saw the situation outside the door, his pupils constricted, and his breathing became heavy and hurried.
His grip loosened, and he fell to the ground, staggering backwards.
"Everyone, stay alert!
"Second, third, and third formation!"
His solemn voice sounded in the earphones.
