The pervasive, subtle influence of the digital pulse, amplified by Julian's unstable mind, was no longer merely an observation. It was an active threat, subtly eroding the coherent reality of Eastbridge. Li Feng, armed with the knowledge of Julian's "new eyes" and the spreading ripple effect, knew he had to move beyond mere monitoring. He needed to counteract.
His chosen strategy was a perceptual shield: a localized, highly focused electromagnetic dampener designed to neutralize the specific frequency range of the pulse's sub-harmonics, thereby stabilizing Julian's perception and, hopefully, preventing further unintended side effects. It was a theoretical long shot, requiring Li Feng to create an inverse wave pattern of an alien signal he barely understood.
He embarked on the most challenging engineering feat of his life. He scavenged more components, pushing the limits of his university-issued credit cards for specialized materials. He designed a series of miniature, high-frequency emitters, each barely larger than a thumb drive, that could be strategically placed within Chloe's house. His code became a complex symphony of inverse Fourier transforms and adaptive noise cancellation algorithms, designed to emit a precisely tuned counter-signal, effectively creating a zone of sensory normalcy around Julian. The complexity was immense; a single miscalculation could amplify the problem, not solve it.
The strain was palpable. His sleep, already minimal, became almost nonexistent. He fueled himself on nutrient paste and the relentless pursuit of the solution. His physical training sessions, once precise rituals, were now frantic, solitary bursts of energy, a way to bleed off the immense mental pressure. His apartment lab was a war zone of wires, glowing screens, and the faint, metallic scent of ozone. He knew he was operating on the very edge of his own capacity.
Meanwhile, the ripples in Eastbridge grew more noticeable. The minor tech glitches Li Feng had observed became more frequent, sparking widespread annoyance. Campus Wi-Fi would inexplicably drop for minutes at a time, then surge with abnormal speed. Digital clocks on public buildings would sometimes jump forward or backward by several minutes, causing confusion. There were isolated reports of pets behaving strangely – dogs staring intently at blank walls, cats attempting to bat at unseen objects. Small, localized power surges were reported to the university facilities, baffling engineers who could find no conventional fault. The Eastbridge Chronicle even ran a small piece on "The Campus's Quirky Glitches," attributing them to aging infrastructure and solar flares, unaware of the hidden cause.
Julian, unaware of Li Feng's surveillance or the subtle countermeasures being prepared, became more erratic. His drawings, Li Feng observed through his sensors, were no longer confined to notebooks. He had begun to use his basement wall as a canvas, sketching immense, interwoven geometric patterns that pulsed with a strange, inherent logic Li Feng's analysis could recognize, even if he couldn't decode its meaning. Julian would speak aloud to these drawings, sometimes pleading, sometimes demanding, obsessed with finding the "next layer." His "new eyes" were clearly evolving, pushing him towards a deeper, more dangerous engagement with the pulse.
Chloe was a wreck. She called Li Feng daily, her voice strained. "He tried to 'recalibrate' the living room lights with his own hands yesterday," she whispered one evening. "He just stood there, waving his hands at them, talking about light frequencies. My parents are talking about getting him professional help, but he just laughs when they mention it." Her fear was palpable. "Please, Li Feng. Please tell me you have a plan. He's not Julian anymore."
Li Feng's analytical mind registered Chloe's desperation, knowing it was an additional, unstable variable. He had to act.
He deployed his miniature emitters under the cover of night, subtly placing them in Chloe's living room, beneath a sofa, behind a bookshelf, and even a tiny one discreetly attached to Julian's own desk in the basement – all connected wirelessly to a central control unit in Li Feng's apartment. Each emitter was designed to be virtually undetectable by conventional means, drawing minimal power, their output precisely tuned.
The moment of activation was tense. Li Feng sat at his console, watching the data stream from Chloe's house. He triggered the dampeners. For a few seconds, the room glowed with a faint, almost imperceptible shimmer that only his sensitive instruments registered. His correlator, monitoring the pulse's sub-harmonics from his apartment, immediately showed a localized dip in their background noise within Chloe's house. The shield was working.
Through his audio feed from Julian's basement, Li Feng heard a sudden, sharp gasp. Julian had been engrossed in his drawings. Now, he slumped, rubbing his temples, a confused frown on his face.
"What... what just happened?" Julian mumbled, his voice less ethereal, more grounded. He looked around the room, then at his complex wall drawings, his eyes no longer possessing that manic, knowing intensity. The strange patterns he had drawn looked, for a moment, foreign to him.
Chloe, Li Feng's other sensor, called him minutes later, her voice laced with confusion and a flicker of hope. "Li Feng? Julian just... he looks less crazy. He's actually coherent for the first time in days. He just asked for a sandwich."
Li Feng allowed himself a micro-expression of calculated satisfaction. The perceptual shield was functioning. He had temporarily dampened the pulse's influence, bringing Julian back from the edge of his altered reality. But this was merely a temporary solution. Julian was still exposed to the raw, pervasive signal, and Li Feng knew the shield couldn't hold forever against the immense, distant power of the pulse. He had bought himself time, but the underlying problem, the echo from deep space, remained. And Li Feng knew the lull would be brief. The next phase of containment would be far more complex.
