Chapter 399: Nano Frenzy

Time slipped away amid the constant flurry of repair work. The scars of war were gradually fading, and life aboard the ship slowly returned to a normal rhythm.

In the blink of an eye, a full year had passed since the intense interstellar battle at Planet Digg.

Over that year, Deep Space was largely repaired. Of course, "largely" was a relative term, restoring the complex weapon arrays and intricate internal systems would likely take several more years to fully resolve.

Reviewing the dwindling inventory reports in the supply bays, Jason, acting as the fleet’s commander, felt a growing knot of anxiety.

Watching their stockpiles bleed away left him constantly on edge.

When recent statistics showed that resource consumption had once again exceeded the projected limits, he felt a surge of frustration with nowhere to vent it.

Resources were the absolute lifeblood of the fleet! But regardless of the cost, Deep Space had to be repaired.

After executing several sharp evasive maneuvers, the colossal ship had successfully navigated out of the primary danger zone and remained in faster-than-light transit.

The view beyond the observation windows remained an unchanging, stretched distortion of starlight.

They were completely blind to the outside universe. Jason often wondered if the hostile empire had angrily nuked Planet Digg into oblivion, or if a pursuit fleet was still hot on their trail.

Jason let out a long sigh. While there were plenty of things to worry about, there were also reasons to celebrate. This past year had been one of recuperation and reconstruction. More importantly, their scientific research had taken a massive leap forward.

"...Nanorobotics is a critical area of future research, applicable to both military and civilian sectors. With our current technological tier, we can now design and manufacture basic nanobots at a scale of ten thousand nanometers, roughly the size of a human red blood cell..."

"The challenges we face fall into two primary categories: manufacturing and structural design.

The manufacturing bottleneck has been resolved thanks to the Gaia entity, Elara. Our main hurdle now is the design phase..."

"...Nanobots are classified into two types: those capable of self-replication, and those that are not..."

On the auditorium stage, the physicist Felix beamed with pride as he presented his newly published paper. It detailed a major theoretical breakthrough in nanotechnology.

By utilizing Elara’s unique biological capabilities, the team had successfully fabricated a microscopic silicon-based chip the exact size of a red blood cell.

Several senior scientists in the audience eagerly peppered him with questions. Felix, clearly enjoying the intellectual engagement, gestured enthusiastically as he answered.

"...In reality, self-replicating nanobots are vastly more complex because replication is an entropy-reducing process.

Therefore, for a nanobot to self-replicate or function like a biological organism, it must absorb negative entropy from its environment, in other words, it needs a continuous supply of usable energy!"

"Yes, energy consumption is currently our primary research focus..."

During the battle, Deep Space had been swarmed by enemy nanobots. Although the vast majority were destroyed by high-voltage currents and extreme thermal purging, some partially intact fragments had been recovered.

These microscopic remnants had become the ultimate research subjects.

Whether it was the immense pressure of the war or a sudden flash of scientific inspiration, the resulting breakthroughs were staggering.

"As you can see in this simulation, to solve the energy deficit, we initially tested chemical agents as a power source. We can model the entire replication sequence through computational simulations..."

"A self-replicating nanobot is suspended in a fluid chemical medium rich in energy and raw materials."

"Initially, the first unit completes its replication cycle in exactly one hundred seconds. The second generation replicates in the same time frame. Two become four, four become eight, and the population scales exponentially..."

"If this chemical medium is supplied continuously without limits, these microscopic machines could theoretically produce a literal metric ton of nanobots within twenty-four hours. Over a few days, the numbers would become apocalyptic..."

"...Of course, relying on chemical agents as a primary energy source carries too many logistical limitations.

Therefore, we are exploring whether wireless energy transmission technology can bridge this gap."

...

Following the symposium, Jason walked out feeling slightly dizzy. The latter half of the presentation had involved a dense barrage of mathematical formulas and advanced technical jargon that had left most non-specialists completely lost.

It was difficult to compress a year’s worth of intense scientific labor into a few hours of lecture. Jason only took away the core concept: energy storage and structural design remained massive hurdles.

A processor the size of a red blood cell naturally possessed a pitifully slow computing speed. Still, taking the first step was always a victory.

During the conference, the scientific council had reached a consensus: Elara’s capabilities could be leveraged to physically construct these nanobots.

This neatly bypassed the immense difficulties of nanoscale manufacturing, leaving the engineers to focus purely on the blueprints.

It was a logical pivot; using Elara exclusively to forge massive naval cannons and hull plating was a profound waste of her potential.

The design phase was fraught with challenges, requiring the formulation of entirely new theories.

However, the miraculous possibilities offered by nanotechnology provided the research teams with boundless motivation.

Jason reviewed a data pad as he walked through the corridors. "Medical teams are developing specialized nanobots designed to navigate the human bloodstream, based on molecular pathology. These units are projected to purge toxins, repair genetic damage, stimulate cellular regeneration, and drastically extend human lifespans..."

"These medical nanobots are still in the prototype phase, ranging from a few millimeters down to a few micrometers in size. We currently have twenty-seven dedicated research groups working on these applications," Jason read aloud.

"Progress is slow, but it’s undeniable that nanorobotics will trigger a true medical revolution in the coming decades. They will help humanity conquer almost all known diseases and eradicate the threat of alien pathogens."

"Furthermore, the theoretical applications are staggering. We could use nanomachines to assemble carbon atoms one by one into flawless diamonds. Sure, we don’t necessarily need diamonds, but the concept of direct molecular assembly is incredible."

"If we can synthesize diamonds... we can synthesize anything. Recombining ambient atmospheric molecules into usable materials... We could theoretically use nanobots to construct rovers, or even entire spaceships!"

Jason continued talking to himself, his expression growing increasingly animated. "...Wait, isn’t that essentially Elara’s innate ability?"

"It’s far more difficult than you think," Lily said, shaking her head as she walked beside him.

Unfazed, Jason pushed on excitedly, "Regardless, nanobots could be deployed in almost every field imaginable—military, civilian infrastructure... How many years do you think it will take to reach that level?"

Lily let out an exasperated sigh. "Spoken like someone who doesn’t do actual research. You are drastically oversimplifying the problem. Nanobots are microscopic.

That makes it incredibly difficult for them to store meaningful amounts of energy, let alone execute highly complex processing tasks."

"Conjuring a capital ship out of thin air using nanobots? That sounds like cheap science fiction."

"Which do you think is more mechanically complex: a single nanobot, or a Space Swallow fighter?"

"Without a doubt, the nanobot!" Before Jason could even guess, Lily delivered the counterintuitive answer. "Even the most rudimentary nanobot is thousands of times more complex than a Space Swallow!"

She sighed, shaking her head. "Think about it. A human red blood cell is one of the simplest biological cells. Yet, if we tried to artificially construct one from individual atoms and molecules, the structural complexity would shatter our current computational limits.

And a red blood cell only performs very basic functions: transporting oxygen and removing carbon dioxide."

"Now consider a nanobot. With our current engineering limits, it has to be far simpler than a red blood cell.

Fabricating a functional machine at the microscopic level is akin to synthesizing a living cell from scratch! It is agonizingly difficult!"

"If you’re dreaming of simultaneously coordinating trillions of nanobots to forge a complex starship... I suggest you wake up. The processing bandwidth and network complexity required for that scale of coordination is unimaginable!"

"Right now, successfully directing a swarm of nanobots to assemble a simple, solid cube of iron is our absolute peak milestone."

Jason chuckled, shaking off her pragmatism. "A man can dream, can’t he? If we ever managed to build warships via nanoscale assembly, industrial bottlenecks would be a thing of the past. Sure, even a Tier 4 empire might struggle to pull that off, but what if we actually do it someday?"

"It’s only been a year. We have a very, very long future ahead of us."

Jason smoothly changed the subject. "Speaking of the technical hurdles, how did your team decide to tackle the energy storage issue?"

Pivoting back to hard science, Lily’s tone turned entirely serious. "First, we are pursuing wireless power transmission, which essentially uses focused magnetic fields to transfer energy. It’s currently our most viable and straightforward solution."

"Second, we are exploring ambient chemical agents. For instance, medical nanobots could be designed to metabolize human blood glucose levels to power themselves..."

"Third... is the holy grail: harvesting vacuum zero-point energy via the Casimir effect! It is the ultimate, inexhaustible energy source, but theoretically, it requires monumental breakthroughs that are currently beyond us."

"For now, we are approaching the problem through bionics, hoping to program the nanobots to mimic rudimentary cellular metabolisms... It is a colossal challenge, both theoretically and practically."

Despite the daunting obstacles she listed, the young scientist didn’t look discouraged in the slightest. Her eyes were bright with unshakeable confidence.
