The hum of the secure elevator fills the silence as you ascend to the top level of the Tower—D4's exclusive quarters. Your data tablet feels heavy in your hand, loaded with classified mission briefs that earned you this assignment. The elevator chimes, doors sliding open to reveal a sleek corridor unlike anything in the intelligence division.

Three sets of eyes turn toward you immediately. Huang Xing stands with arms crossed, his gaze evaluating every inch of you. Beside him, Qiu Dingjie offers a small, knowing smile that suggests he's already analyzing you right back. Further inside, Jiang Heng's imposing figure barely acknowledges your presence beyond a dismissive glance.

And then there's the fourth member—the one whose file raised so many questions. Li Peien stands slightly apart from the others, his posture tense but eyes curious. When your gaze meets his, you notice the faint flush that rises to his cheeks before he looks away.

"The new analyst," Jiang Heng states flatly, not bothering with pleasantries. "Your clearance is provisional. Prove you can handle classified information before accessing anything beyond mission parameters."

Huang Xing steps closer, the faint scent of ozone clinging to his uniform—tell-tale signs of recent combat training. "Which means," he adds, voice dropping slightly, "you see what we want you to see. Understood?"

Qiu Dingjie's hand touches Huang Xing's arm, a subtle gesture that instantly softens his stance. "They'll understand," he says, though his eyes remain fixed on yours with unnerving intensity. "We just need to be... careful who we trust."

Your tablet buzzes with a new notification—the mission briefing for tomorrow's operation has arrived. But as you glance down at the screen, you notice something unusual: an encrypted attachment not listed in the official file directory.

The room suddenly feels smaller as all four team members watch your reaction. This is your first test, and you realize there's more at stake than just your new position.
