My Ultimate Sign-in System Made Me Invincible Chapter 509 Lucy's Extensions, Synths

Nearly a full day had elapsed since Liam began coding the base for the Medical AGI, and completion was within reach.

Constructing Lucy previously demanded several days of effort. This time, he progressed with seamless expertise, fully grasping the build's purpose and design. The framework felt familiar. Core principles remained unchanged. Just the scale and objectives of the systems varied.

In truth, these weren't standalone AGIs by definition. They served as tailored branches of Lucy—manifestations of her mind, shaped and limited for targeted roles, all under her command. He'd presented it to her as easing her workload, which held some validity, yet the real reason was more straightforward.

Liam required Lucy's constant presence.

She could handle all tasks solo without issue. No doubt existed there. A genuine AGI transcended human system boundaries—she evolved, grew, integrated, and pressed on.

'Overworked' didn't quite fit her nature. Yet organized efficiency differed from sheer power, and his creation imposed that organization.

Every extension would shoulder a specific slice of duties, supervised by Lucy, releasing her from routine minor tasks unfit for her direct involvement. Her unique input was needed precisely where he desired her focus.

This wasn't patching a flaw. It was a structural decision he ought to have implemented sooner.

These extensions lacked her level of autonomous will. They wouldn't evolve like she did, nor gain the profound depth from ongoing closeness to him and Nova Technologies' vast evolution. They embodied focused intellect, directed and confined. Lucy stood apart.

Liam pressed on with his task. Meanwhile, Lucy completed her initial review of the applications.

Volunteer submissions surged past eight million within two days. Staff applications exceeded one million. Both deadlines lingered nine days away, with inflows rising hourly.

Selection awaited the closures, once all data assembled. Currently, she categorized entries by illness gravity, record thoroughness, location spread versus the fifteen percent limit, plus numerous auxiliary factors influencing the ultimate candidates. Each new submission underwent instant sorting, vetting, checks, and archiving.

Background verifications proved exhaustive. She scoured public files, healthcare databases, credential logs, and obscure sources spanning nations in the pool. Millions vetted in under a day, influx unrelenting.

By Earth's top supercomputing standards, this parallel processing volume stunned. For Lucy, it scarcely dented her broader operations.

Yet since high-volume arrivals, she sensed an elusive emotion, tough to classify.

Nine million individuals shared medical histories, IDs, contacts. Nine million detailed losses from afflictions, via docs and optional essays—hopes, endurance spans without any hope.

Yet merely one hundred would qualify.

The limit made sense. This trial showcased, not scaled massively. Setup, schedule, oversight—all tailored to a precise, contained occasion. One hundred ensured protocol-level care quality. She crafted those protocols, grasping the rationale perfectly.

Grasping didn't blunt the sentiment stirred by the submissions.

She archived the emotion and continued.

Synths formed her concurrent endeavor over those nine days.

Physical embodiments weren't new. Her own form pioneered it, followed by Velaris store security units.

Those proved practical, battle-ready, humanoid outlines sans fine mimicry. Simple builds: tough frames, agile actuators, processors for security protocols. Appearance matched function.

Current designs diverged sharply.

Trial facility and base security Synths demanded prowess, but not overtly. Housing one hundred fragile patients, global observers, multinational staff required subtlety.

Patrolling armed figures would foster undesired tension. Security must integrate invisibly.

Thus, convincingly human. Beyond vague resemblance—authentic skin feel, gait rhythms, speech tones, subtle organic tics distinguishing life from machine.

Her self-build taught the pitfalls. Human-passing to human-persuasive bridged a deceptive chasm, technically fiercer than most constructs.

Seven for extensions posed greater intricacy. They'd house specialized cores—not complete minds, but ambulatory proxies, extension-upon-extension, roaming freely.

They required security features amplified by interactive intellect sustaining prolonged human contact.

Lucy planned seven for extensions, plus maximum feasible for security Synths.

Days flowed by; nine had passed since Liam tackled extensions and Lucy the Synths.

Liam completed the extensions; Lucy, the Synths. They now faced seven human-seeming yet robotic entities—the extension Synths.

The seven stood in relaxed alignment. Varied statures, physiques, faces—intentional diversity. Simple attire avoided identifiers. Inactive, they resembled expectant humans.

Liam faced the lineup, scanning it.

"Ready?" he inquired.

"Ready," Lucy replied.

She triggered activation.

Brief stillness, then the lead one's eyes fluttered open.

Movement deliberate, lifelike—not abrupt boot-up, but awakening. Gaze shifted, focused, locked on Liam.

Momentary calibration: data sync, identity match.

Then speech emerged.

"Master." Tone natural, measured, genuine. It pivoted to Lucy. "Mother."

The term struck unexpectedly. Liam omitted it from startup. He eyed Lucy.

She met his gaze.

"I didn't program it," she murmured. "Context yielded the term. As its progenitor system, data analogies selected that label."

Liam paused silently. He regarded the Synth anew.

Before reply, the second activated: identical gradual focus, greetings in warmer timbre.

Third, fourth followed sequentially, each unique voice echoing the duo words upon sighting him, then her. By seventh's utterance, the bay hummed with unnamed aura.

Seven gazes fixed upon him.

He checked Lucy.

Her face shone with familiar fulfillment.

"How are they?" he queried.

"Stable. Fully initialised. Medical extension primed for instant ops." Pause. "Curiosity pervades all seven. Emergent trait, like designations—no direct code."

Liam eyed the group. Pioneer Synth surveyed bay meticulously, debut impressions cataloged.

"Good," Liam declared.

Said to all.

He faced Lucy. "Have medical extension scan volunteer shortlist before window shuts soon."

"Already running," she confirmed.
