Round 209

The walls' synchronized breathing stopped completely—everything except that low pulsing hum growing stronger like a heartbeat counting down seconds until next adaptation phase. Halie staggers backward, vision blurring—her right arm's coordination failing completely now, fingers curling into what should be a fist but instead twitch in spasms she can't control. The walls pulse faster in response to her movement, their synchronized breathing pattern shifting like they're tracking her position specifically. "We can't trust that staircase," Halie says, voice strained despite the effort at calm. "The corruption downstairs—it's intelligent, learning our patterns between breaths." I take a deep breath, trying to calm my racing heart as I step back from the threshold of the doorway leading down. Halie's words echo in my mind—the corruption downstairs is intelligent, learning our patterns between breaths. Splitting up now would be playing right into whatever's waiting for us down there. My eyes dart around the corridor, searching for another way out. The walls seem to pulse with an otherworldly energy, their ancient stone surface rippling like flesh. I can feel the pulsing rhythm in my own chest now, matching the walls' frequency—fuck, it's getting inside somehow.
