Virginia, Langley.
Yang Yi didn't choose to reveal his identity at a CIA workstation; he went directly to the United States, to Virginia, Langley, which is the headquarters of the CIA.
Risking it all, but Yang Yi didn't feel particularly nervous, but rather a mix of excitement, tension, and slow-building anticipation, not unlike the feelings of an actor about to take the stage.
The CIA headquarters didn't look particularly imposing, and at a glance, the security didn't seem overwhelmingly strict from the outside. But that was just the facade; in reality... the security wasn't particularly tight.
Yang Yi walked straight towards the CIA's main entrance, drawing near to the door when he was stopped by a sentinel.
"Halt! Show your identification or turn around and leave."
The CIA headquarters had soldiers on duty, but the one stopping Yang Yi was a staffer in a suit instead of a military uniform.
