Twilight enveloped the city.
A black private car entered the underground parking lot of the Qingtai Hotel and stopped near the VIP elevator.
Two people got out of the car, one a tall and thin man in a black suit with an indifferent face, the other a young man in sportswear donning a duckbill cap and a mask, his features unclear.
"I'll wait here for you, you go ahead," the tall and thin man said expressionlessly.
The young man in sportswear looked around, pressed down the brim of his cap to better hide his face, and then headed towards the VIP elevator in the underground parking lot.
After passing iris recognition, the young man entered the elevator.
The elevator doors closed and began descending rapidly.
When the elevator stopped and the doors opened again, it had reached a long and secluded corridor.
At the end of the corridor was a large metal door.
The young man in sportswear approached the door and passed another round of iris and fingerprint recognition.
