After an extensive review of Noah's tracker removal documentation, Circuit and Lisa turned their attention to me as I waited in the chair, my mind still processing the enormity of what Noah had revealed.

  "Alright," Circuit began, her mechanical appendages settling into a more relaxed configuration behind her back. "Here's the situation. The removal procedure is complex, but Noah's documentation is thorough. Lisa will assist, but we'll need to put you under and temporarily shut down your internal system."

  I nodded, familiar with standard protocols for implant surgery.

  "But first," she continued, extending one of her auxiliary limbs to a nearby console, "I want to examine what Aurora is actually doing to your Receptacle."

  "We need to understand the modifications Noah implemented," Lisa added, moving closer to the chair. "Your Receptacle is behaving in ways completely outside MainFrame's design parameters. A proper diagnostic will give us crucial information before we proceed with removing the tracker."

  A holographic keyboard materialized before Circuit, her fingers dancing across the illuminated keys with practiced precision. Almost immediately, my heads-up display illuminated with diagnostic feedback—but the interface was nothing like the standard MainFrame diagnostics I'd seen during routine maintenance.

  "This is different," I observed, studying the unfamiliar readouts.

  "Yes," Circuit confirmed without looking up from her work. "This is a diagnostic directly from Aurora. The Receptacle OS has been bypassed, and what you're seeing is the actual system activity instead of the sanitized readout MainFrame designed to keep Couriers in the dark."

  A second window appeared in my visual field—a three-dimensional representation of my brain with the Receptacle clearly visible at the base of my skull. What should have been a compact, self-contained unit had transformed dramatically. Tendrils of new material extended outward from the original implant, forming structures that resembled electronic modules but with an organic quality to their growth patterns.

  "This is incredible," Circuit breathed, her eyes widening as she examined the display. "Your Receptacle isn't just running alternative software—it's physically expanding, building new hardware modules and neural interfaces that were never part of the original design."

  "How?" I asked, struggling to comprehend the transformation occurring inside my own head.

  "Nano-technology," Lisa said softly, leaning forward to study the display with an expression of disbelief. "My father actually implemented it." She shook her head, struggling to process the implications. "This shouldn't even be possible. Nano-technology has been theoretical for decades—one of those technologies from the old world that scientists believed would revolutionize everything but never materialized. It became just another broken promise, like flying cars and clean energy and all that crap that never happened."

  "The theoretical barrier wasn't technological," Circuit added, a mechanical appendage extending from her back to tap a command sequence. "It was economic. The collapse of global research networks during the Great Decline meant nobody had the resources to develop it properly. Yet here it is—functional molecular machines building complex structures inside your brain." She looked up at Lisa. "If MainFrame developed this in secret, what else might they be hiding?"

  One of Circuit's mechanical arms reached for a box of cookies on a nearby table, bringing it to her while her eyes remained fixed on the display and her hands continued typing on the holographic keyboard.

  Circuit's fingers flew across the holographic interface, isolating specific components of the expanding system. "This explains so much. I think I know how you were able to hack those people in Boz's shop."

  I started to turn toward her, but one of her mechanical appendages gently pushed my head back into position.

  "Don't move," she instructed firmly. "Watch your display."

  On the 3D model, one module illuminated in electric blue.

  "These," Circuit explained, using a virtual pointer to indicate the highlighted structures, "are high-frequency wireless transmission modules. NeuroSlicers use similar tech, but these are fundamentally different."

  One of mechanical appendage retrieved two cookies from the box and delivered them to her mouth.

  She chewed thoughtfully, zooming in on a particular structure. "Those wireless transmission components are beyond anything commercially available. A normal wireless neural implant can manage maybe 500 megabytes per second under optimal conditions. These miniaturized versions are pushing close to 5 gigabytes download and 3 upload. That kind of bandwidth in such a small neural implant is theoretically impossible."

  "How is Aurora achieving this?" Lisa asked, circling the chair to examine the display from another angle. "Even the most advanced NeuroSlicers don't have access to technology like this."

  "I can only assume it's proprietary MainFrame R&D that never made it to market," Circuit replied, one of her mechanical arms grabbing more cookies. "Your father must have had access to experimental tech that even most MainFrame employees don't know exists."

  Her mechanical appendage hovered near her face with two cookies, waiting briefly as she quickly swallowed her previous mouthful without looking away from the display. The moment her mouth was clear, the mechanical arm efficiently deposited the fresh cookies, continuing this practiced rhythm as she resumed her analysis. Crumbs occasionally fell through the holographic keyboard, causing momentary distortions and flickers in the projected interface as the particles passed through the light constructs.

  She continued typing rapidly, undisturbed by the momentary distortions, as additional data streams materialized alongside the 3D model.

  "The architecture is fascinating," she continued between bites. "These new modules initially route all processing through the Receptacle chip, but they're gradually establishing direct neural connections to the host brain. That's why you experience those headaches and nosebleeds—your neural pathways are being physically and organically reconfigured in real-time."

  "Host brain? You mean I'm the host?" I asked, the implications settling uncomfortably in my mind.

  "Well, yeah, dummy!" Circuit replied with characteristic bluntness. "Of course you're the host! These modules are using you—your body, your brain—as a biological foundation to grow into. What did you think was happening?"

  The display updated to show lines representing the forming neural connections, many pulsing with an unstable rhythm.

  "The direct brain interfaces are still in early development stages," she noted, studying the fluctuating patterns. "Routing through the Receptacle is more reliable at this point since these new neural pathways aren't fully stabilized. Watch this demonstration."

  On the 3D model, particles of light emerged from the NeuroDoc chair, flowing through the neural pathways of my brain toward the wireless module. As they moved, the connecting lines shifted from stable blue to angry red before fragmenting entirely.

  "See that?" Circuit pointed, one of her mechanical arms absently reaching for more cookies. "I'm sending a simple data packet, simulated from the chair but configured to appear as if it originated from your neural cortex. The connection destabilizes almost immediately—packet loss, signal degradation, and complete disconnection. The interface is incredibly fragile."

  "Now watch this," she said, initiating a second simulation. This time, the particles of light originated from the Receptacle itself—from Noah's Soul—and flowed toward the wireless module. The connection remained bright, stable blue throughout the entire process.

  "Fascinating," she murmured. "Commands originating from Noah's Soul maintain nearly perfect stability when interfacing with the new modules. The Aurora system prioritizes this pathway while the direct connections to your consciousness are still developing. That's why you experience those moments when Noah seems to take control—he's not actually controlling you, but his Soul can communicate with these modules much more efficiently than your consciousness can right now."

  "So eventually, I'll be able to use these abilities without Noah's involvement?" I asked.

  "Theoretically, yes," she confirmed. "As these neural connections strengthen, the distinction between what's 'you' and what's 'Noah' will continue to blur. The system is continuously rebuilding and strengthening these pathways."

  Lisa nodded, her expression thoughtful. "It's a genuine symbiosis rather than a replacement, just as my father explained."

  I nodded, finally beginning to understand the profound transformation occurring within my brain.

  Circuit's mechanical appendage delivered another two cookies toward her mouth, but before they could reach their destination, Lisa swiftly snatched one with surprising speed. Circuit shot her a scandalized glare as Lisa popped the stolen cookie into her own mouth with a mischievous grin. Circuit's mechanical arm hesitated momentarily, as if recalculating, before depositing the remaining cookie into her mouth with an exaggerated possessiveness. She chewed thoughtfully, still eyeing Lisa with mock indignation, before typing a new command sequence.

  "There's something else," Circuit added, her tone shifting to something more ominous. She manipulated the display to focus on another structure forming within my brain. "Aurora is building multiple new modules throughout your neural system, but most are too early in development to identify their purpose. However, this one is far enough along to recognize, and it's particularly concerning."

  The 3D representation zoomed in on a complex device taking shape near my frontal lobe.

  "This," she said with unusual gravity, "is a Vibration Emitter—military-grade tech that's absolutely illegal in ToxCity. They're rare even in Neo Underground."

  "Vibration Emitter?" I repeated, the term completely unfamiliar to me.

  "I thought those were theoretical," Lisa said, her expression darkening. "The military discontinued development after the test phase disasters."

  "They exist," Circuit corrected her. "I've seen a few in Neo Underground, but they're crude compared to this." Her mechanical arm deposited the last two cookies into her mouth before discarding the empty box. "This design is generations beyond anything I've encountered."

  My curiosity outweighed my apprehension. "What exactly does it do?"

  Circuit wiped crumbs from her mouth with the back of her hand, her expression uncharacteristically solemn as she leaned forward until her face was centimeters from mine.

  "Remember what happened at NeoDuck?" she asked.

  I nodded, the memory still vivid despite the fractured nature of my recollections.

  "That massive enforcer who seemed to explode from the inside out?"

  Another nod.

  "That's what a Vibration Emitter does," she explained. "It broadcasts targeted, invisible vibration signals that resonate with specific frequencies of metallic implants, forcing them to vibrate with catastrophic intensity." She tapped a sequence on her keyboard before leaning in again. "The larger the target implant, the more devastating the result."

  Her face split into a morbid grin as she continued. "Like, for example, causing fully cybernetic muscle systems to vibrate so violently they tear through the surrounding tissue and explode outward from a person's chest cavity."

  She leaned back, shaking her head in amazement.

  "This is absolutely insane," she declared, unable to contain her excitement despite the disturbing implications. "This is technology that most people don't even know exists, let alone how to fabricate. The fact that your Receptacle is autonomously constructing it at the molecular level is unprecedented."

  "But how is it creating these structures from nothing?" Lisa interrupted, her brow furrowed with concern. "Even nano-technology requires raw materials."

  "It's not creating from nothing," Circuit replied, her enthusiasm dimming slightly. "It's repurposing cells from your body. Brilliant engineering, but potentially dangerous for you over time."

  I exchanged a worried glance with Lisa, who placed a gentle hand on my arm.

  "How could my father allow that?" she asked, her voice tight with concern. "What's the long-term risk?"

  Circuit's fingers flew across the holographic interface once more.

  "It's not immediately life-threatening," she clarified. "But it is diverting biological resources your body needs for normal function. That said, I think Noah anticipated this issue." She navigated through the file system on the memory stick. "I remember seeing something while browsing earlier... here it is."

  A document materialized on the display with the title "Helping Aurora's Growth."

  "Impressive," Circuit murmured as she scanned the extensive file filled with diagrams, chemical formulas, and procedural notes. "Noah documented a method not only to mitigate the biological impact but potentially accelerate the integration process. I'll need time to study this thoroughly, but it looks promising."

  Lisa squeezed my arm reassuringly, though her smile remained strained. "That's good. But first, let's rid you of this tracker."

  "Absolutely," Circuit agreed, preparing the surgical systems. "I'm going to power down your systems now."

  "Wait," I interjected, a thought crystallizing in my mind. "Is it possible to remove the tracker without destroying it?"

  They both looked at me with confusion before exchanging a glance with each other.

  "Well," Circuit hesitated, "if I remove it, it will likely deactivate. That's kind of the point."

  "Could you keep it operational while disconnecting it from my Receptacle?" I pressed.

  Understanding dawned in Lisa's eyes. "Oh shit, I know!"

  I nodded, confirming her realization.

  Circuit studied me for a moment, then broke into a broad grin. "Clever. I'll do my best to maintain its functionality. Now, time for you to take a little nap."

  As she initiated the shutting down protocol, my vision began to blur at the edges. The last thing I saw before consciousness faded was Lisa's determined face, her expression a mixture of concern and resolve.

  Whatever we were stepping into, there would be no turning back.
