The atmosphere in the agency's central intelligence wing was perpetually thick with tension, but that evening, an oppressive weight hung in the air, causing every breath to feel laborious. As the fluorescent lights cast an unforgiving glow, Song Yn found herself abruptly called into action. One moment, she was buried in the gritty details of routine reports at the field office, her mind focused on sifting through the mundane. Next, her phone buzzed sharply against the polished desk, vibrating with an urgent coded message that shattered the monotony, summoning her into the unknown:
‘Report to the Sub-Level Five. Immediately.’

Sub-Level Five was no mere hallway; it was a realm where routine took a backseat, and shadows morphed into intricate strategies. It was a place that summoned agents only when the stakes escalated to a level that rattled the very foundations of national security. Yn felt her heart race, a thrilling undercurrent beneath the veneer of her composed facade—the kind of calm that sent shivers down the spines of even the most hardened criminals in interrogation rooms.
