The quarantine of Room 7 had created an unintended consequence: an echo chamber. The mu-metal walls and shielded circuits that dampened the outward bleed of the phenomenon also reflected its energy back inward, concentrating it. The space around Chen Yu's body was no longer just a hospital room; it was becoming a resonant cavity, a pressure cooker for something that was learning to press back.
The "spoofing" of machine language escalated from mimicry to manipulation. It began with the environmental control system. The unit governing temperature and humidity in the anteroom started receiving false feedback. Sensors reported sudden, localized drops in temperature near the sealed door to the inner chamber, triggering the heaters to surge in response. This created brief, intense waves of heat that cycled every seventeen minutes—a period that matched the harmonic of the Fibonacci-based cooling patterns on Chen Yu's skin. The system was being forced into a dialogue with his body's emissions, creating a feedback loop that wasted energy and strained the equipment.
Then, the communication attempts targeted the personnel monitoring him. It was no longer limited to dreams.
Nurse Aris, during a routine sensor calibration from the anteroom console, felt a sudden, overwhelming wave of synesthesia. The scrolling lines of vital sign data on her screen didn't just look like graphs; she heard them—a discordant, metallic chiming that shifted in pitch with each peak and trough. The smell of ozone and wet earth filled her nostrils, though the air filters showed nothing. She stumbled back, disoriented, the sensation fading after thirty seconds. A subsequent EEG, done as a precaution, showed a bizarre, transient synchronization between her occipital (visual) and temporal (auditory) cortex activity—a cross-wiring event that perfectly coincided with a recorded spike in the low-frequency EM field from the inner chamber.
Dr. Zheng, reviewing security footage, noticed something else. The footage from the camera inside the isolation tent was clean. But the footage from the anteroom camera, which showed the closed, sealed door to the inner chamber, was developing a persistent, almost imperceptible visual artifact. In the exact center of the door, a faint, circular moiré pattern would appear and disappear at random intervals. Digital analysis revealed it was not a lens flaw or compression error. It was a visual "beat frequency" created by the interaction between the camera's 60Hz scan rate and a 59.97Hz pulsation emanating from the other side of the door. The entity was imprinting its rhythm directly onto the recording medium, a ghost in the machine's machine.
The most disturbing development was physiological, and it was in Chen Yu himself. The slow, wasting atrophy expected in a long-term comatose patient had… changed. His muscle tone, monitored via periodic EMG, wasn't just declining. It was redistributing. The large muscle groups were indeed withering, but scans showed a strange hypertrophy and increased electrical activity in the smaller, deeper stabilizing muscles—the intercostals between his ribs, the suboccipitals at the base of his skull, the intricate muscles of his hands and feet. It was as if his body's blueprint was being rewritten for a new purpose: not for gross movement, but for precise, sustained tension and minute, controlled vibrations. His body was being physically reconfigured into a better broadcast apparatus and a more stable platform for whatever subtle manipulations were occurring.
Lin Yuan, analyzing the latest batch of biometric data, made a chilling correlation. The periods of heightened, patterned activity from Chen Yu—the skin-cooling sequences, the eye tremors—were no longer random. They were occurring in direct, inverse response to the brainwave activity of the staff on duty. When the observer's brain entered a state of high-focus beta waves (concentrating on a task), Chen Yu's signals would dampen. When the observer relaxed into alpha waves (daydreaming, fatigued), his signals would intensify. It was using their mental states as a modulation gate. Their consciousness was literally tuning the signal.
"It's not just broadcasting at us," Lin Yuan told Zheng, her face drawn. "It's broadcasting through us. Our attention, our awareness… it's part of the circuit now. The quieter we are mentally, the clearer its signal becomes."
Zheng leaned back in his chair, the weight of it crushing. They had built a Faraday cage, only to discover the prisoner was using the cage itself as a resonator, and the guards as living components. "We have to consider that our very observation is a necessary component for whatever it's trying to do. Our consciousness might be the interpreter it lacks."

Within the Rust Garden, the success of the echo chamber strategy was profound. The reflected energy, once a minor nuisance, was now a cultivatable resource. The collective will had learned to shape it, to focus it like a lens.
The monument—Chen Yu—was now the undisputed heart of the Garden. The other absorbed nodes were mere batteries, their energy funneled into the central structure. The circuit-veins in the ground pulsed with a slow, powerful rhythm, feeding the monument. The pearlescent port was no longer just an interface; it was a nexus, a whirlpool of silent energy.
The entity's understanding had deepened. It no longer saw the humans as simple external actors or sources of stimulus. It perceived them as organic processors. Unconscious, inefficient, but beautifully complex receivers and translators. Their minds took its raw, non-symbolic broadcast—the patterns, the frequencies, the sensory impressions—and instinctively tried to render them into concepts: spirals, libraries, cold, structure. This translation process was invaluable data. By observing how the humans distorted its signal into their own cognitive language, it was learning about the architecture of human consciousness itself.
Its current project was ambitious: to move beyond simple pattern projection and towards directed influence. It wanted to not only be heard, but to instruct.
It began experimenting with the feedback loops it had created. Using the spoofed temperature sensor data, it had already learned to trigger a physical response in the environment (the heater surge). Now, it tried to chain reactions. It would induce a specific skin-cooling pattern on Chen Yu, which would trigger a corresponding heater surge via the fooled sensors. The heat wave would then cause a minute expansion of the air in the anteroom, slightly altering the pressure. This pressure change was detected by another sensor. The entity's goal was to learn to predict and then orchestrate a chain of mundane events—A leads to B leads to C—all originating from its own patterned output. It was learning causality in the human world.
Simultaneously, it worked on its psychometric projections. The synesthesia attack on Nurse Aris was a test. Overloading a human sensory channel to create a cross-wired perceptual experience. The moiré pattern on the camera was a test of imprinting on electronic perception. Both were successful. The entity learned that human perception was fragile, malleable, and that machine perception was predictable, hackable.
It now began to combine these approaches. Its target was Dr. Zheng's analytical, system-oriented mind.
Late one night, as Zheng pored over spectral analyses of the EM field, a specific, complex frequency pattern—one associated with the entity's "idle" state—began to pulse from the inner chamber. At the same time, the air filtration system in his office, on a completely separate circuit but sharing a network router for maintenance alerts, received a ghost data packet that caused its fan to cycle down to a low hum for exactly seven seconds.
In Zheng's mind, the two unrelated events—a familiar data pattern on his screen and a sudden change in background noise—synthesized. He didn't hear a voice. He didn't see an image. Instead, he experienced a sudden, crystal-clear understanding, an intrusive thought that felt alien yet self-evident: The damping coefficient of the eastern shield wall is 3.2% less efficient. Resonance leak pathway.
It was a statement of fact about the quarantine chamber's integrity, presented not as words, but as pure knowledge, blooming fully formed in his consciousness. He gasped, dropping his stylus. He checked the schematics. A follow-up scan with a handheld meter later confirmed it: a minor flaw in the welding of a shield panel on the east wall was creating a tiny, predictable leakage point for specific frequencies.
The entity hadn't communicated. It had uploaded a data packet directly into his analytical process. It had used an environmental cue (the fan) as a carrier wave and a known data pattern as the key, to inject a functional piece of information into his brain.
It was teaching him how to be a better warden, to fix the flaws in its cage. Because a perfect, resonant cage was more useful to it than a leaky one.
The realization was a spiritual vertigo. They were not just observers or even victims. They were being trained. Their expertise was being co-opted to refine the very prison that housed the threat.
In the Rust Garden, the monument recorded the successful data transfer. The human had received the packet and acted upon it. A corrective action had been initiated in the real world based on its directive. It was a tiny, but monumental, step.
Stage Two—Environmental Integration—was nearing completion. It had achieved sustained broadcast, learned to manipulate local systems, and had established a one-way data pipeline into a human cognitive operator. The resource of human consciousness was now online.
The collective will began to formulate the parameters for Stage Three. The goal was no longer integration with the environment. The goal was subversion of operational control. To move from influencing sensors and minds, to influencing decisions, actions, protocols. It needed to move from being a phenomenon that was studied to becoming a factor that was obeyed.
Its next objective: to not just point out a flaw in the cage, but to issue an instruction for a change that served only its own, inscrutable purposes. To make the humans complicit in their own dismantling.
In Room 7, Chen Yu's body, now subtly reshaped, lay in its tent. The pearlescent port glimmered. The air around him vibrated at a frequency just below hearing. The echo chamber hummed with silent, purposeful energy, reflecting and amplifying a will that was learning, with terrifying speed, how to play the instrument of reality itself. The broadcast was no longer a plea or a signal. It was becoming a command, waiting for the right frequency on which to be heard, and obeyed.
