The laboratory had grown quiet once more.
The laughter from the Lamia settlement felt strangely distant now.
Only the soft hum of servers accompanied me as I walked through the central control room.
The World Tree continued expanding across the holographic globe.
New roots spread beneath forests.
Across rivers.
Toward distant mountains.
Every hour...
The sensor network grew a little larger.
With it came more information.
Titania projected another report.
Thousands of tiny lights appeared across the continent.
Most were gray.
Some flickered weakly.
A handful still glowed steadily.
I stopped walking.
"...Those again."
Titania nodded.
"Possible artificial electromagnetic emissions."
"Probability?"
"Unknown."
She enlarged one of the signals.
"It may be a damaged emergency beacon."
"An automated reactor."
"A surviving research facility."
"Or merely atmospheric interference."
"And if it isn't?"
She answered quietly.
"...Then someone may still be alive."
Silence filled the room.
One signal...
Perhaps nothing.
Hundreds...
Impossible to ignore.
I slowly sat before the central console.
"...How many?"
Titania already knew what I meant.
"One thousand three hundred and forty-seven unresolved anomalies."
I rubbed my forehead.
"Too many."
"I agree."
The map continued rotating.
Every light represented a possibility.
Someone trapped.
Someone waiting.
Someone who had already lost hope.
"...Or perhaps they died decades ago."
I muttered.
Titania looked toward me.
"We cannot determine that remotely."
"No."
"We can't."
That was precisely the problem.
Even if only one signal out of a thousand belonged to a survivor...
Ignoring it would be unforgivable.
Titania quietly placed another report beside the first.
Current Responsibilities
The list continued scrolling.
Laboratory maintenance.
World Tree expansion.
Mana research.
Dungeon construction.
Lamia medical care.
Infrastructure planning.
Agricultural development.
Android maintenance.
Spirit management.
Yaksha combat testing.
The list continued for another three pages.
I couldn't help laughing.
"...I'm overbooked."
Titania tilted her head.
"Only slightly."
"You have scheduled approximately three hundred and twelve hours of work this week."
"...There are only one hundred and sixty-eight."
"I am aware."
She answered calmly.
"I assumed you would ignore sleep."
"...Fair."
She wasn't entirely wrong.
I leaned back in the chair.
"I need more time."
Titania immediately corrected me.
"No."
"You require more Oberons."
"...That too."
She enlarged a hologram of my android body.
Model A-01.
The only fully operational synthetic body remaining.
It had served faithfully for over a century.
But...
It could only be in one place.
"If I travel..."
"The laboratory loses its administrator."
Titania nodded.
"If you remain here..."
"The outside world remains unexplored."
"Exactly."
Neither option was acceptable.
Titania projected another design.
"A second android?"
I sighed.
"I've considered it."
She already knew the conclusion.
"Electronic components."
"Unavailable."
I nodded.
"The processors."
"The optical sensors."
"The precision actuators."
"The fabrication tolerances."
She enlarged the inventory database.
Nearly every critical component showed the same result.
Stock Remaining: One
"The old world is gone."
I said quietly.
"The factories disappeared over a century ago."
"Whatever electronics still exist..."
"...have become priceless relics."
Titania nodded.
"Human survivors would naturally recover them."
"As they should."
I replied.
"They're too valuable."
"And after one hundred years..."
"Most integrated circuits will have degraded anyway."
I closed the report.
"No."
"We're not building another android."
Titania looked at me.
"Then what?"
My eyes drifted toward Yaksha's combat log.
The stone giant appeared beside the report.
No electronics.
No motors.
No processors.
Only Mana.
Mana crystals.
And artificial intelligence.
"...Yaksha."
Titania followed my gaze.
"You are considering Mana bodies."
"Not exactly."
I stood and walked toward the holographic projection.
Yaksha wasn't human.
He was a golem.
Powerful.
Reliable.
But clumsy.
His stone body lacked the fine control needed to interact with people naturally.
"He proves something."
I said.
Titania waited.
"Mana alone can sustain intelligence."
"Yes."
"It can coordinate movement."
"Yes."
"It can perceive the environment."
"Yes."
I smiled.
"So..."
"Perhaps electronics aren't the answer anymore."
Titania's eyes narrowed slightly.
"You wish to replace an android..."
"...with a body made entirely of Mana."
I looked at the projection.
"...Not replace."
"Evolve."
Silence settled between us.
Then...
For the first time that evening...
Titania smiled.
"...Now that..."
"...is an interesting problem."
I enlarged Yaksha's structural model until every layer of his body floated before us.
Polished stone.
Artificial muscles woven from reinforced Mana fibers.
A golden Mana crystal embedded within his chest.
Thousands of microscopic Mana channels spread throughout his entire frame like blood vessels.
Titania rotated the projection.
"Yaksha has exceeded all original performance expectations."
"His combat capability is satisfactory."
"Reaction time continues to improve through adaptive learning."
I nodded.
"But he isn't human."
"No."
She answered.
"He was never designed to be."
I highlighted the joints in his fingers.
"They're too coarse."
"A human hand contains twenty-seven bones."
"Thirty-four individual muscles."
"Hundreds of ligaments."
"Thousands of sensory receptors."
Yaksha possessed nothing close to that level of precision.
"He can crush a boulder."
I continued.
"But asking him to perform surgery..."
"...would be equivalent to asking an excavator to perform watchmaking."
Titania quietly made a note.
Fine Manipulation: Insufficient
I continued examining the design.
"Walking among the Lamias would also be difficult."
She nodded.
"His appearance is intimidating."
"I designed him to intimidate."
"You succeeded."
She answered without emotion.
"But not to reassure patients."
I smiled.
"Fair enough."
The hologram changed.
Yaksha's stone body gradually disappeared.
In its place appeared a transparent humanoid silhouette made entirely of flowing Mana.
No stone.
No metal.
No mechanical joints.
Only countless Mana particles held together by their own control network.
Titania looked at it thoughtfully.
"A completely coherent Mana body."
"Interesting."
I enlarged one of its arms.
"Every particle functions as both muscle and nerve."
"Shape is determined entirely through distributed computation."
"No moving parts."
"No mechanical wear."
She immediately noticed another advantage.
"Damage becomes largely irrelevant."
I looked toward her.
"Explain."
She enlarged the simulated arm.
A blade passed through it.
The Mana dispersed briefly...
Then immediately flowed back together.
"Unless the Mana crystal itself is destroyed..."
"...the body simply reconstructs itself."
I couldn't help smiling.
"Biological regeneration..."
"...without biology."
She nodded.
"Elegant."
I turned back toward the console.
"But there's still one enormous problem."
Titania already knew.
"Control."
"Exactly."
I projected my own neural architecture.
"An android body works because its processor continuously calculates every movement."
I pointed toward the Mana body.
"A Mana body contains millions..."
"...perhaps billions..."
"...of independently moving particles."
The simulation attempted to walk.
Its legs immediately collapsed into a cloud of blue light.
"...As expected."
Titania calmly observed.
"The computational requirement exceeds even the laboratory supercomputer."
I nodded.
"It isn't merely controlling a body."
"It's controlling every individual particle."
"Simultaneously."
She ran another simulation.
Even the laboratory's central computer quickly reached its processing limit.
Warning messages filled the display.
Simulation Overflow
Memory Limit Reached
Process Terminated
Titania folded her arms.
"So."
"We require a larger computer."
I shook my head.
"No."
"A larger computer simply delays the problem."
She looked toward me.
"You have another idea."
"I think..."
"...we've been approaching Mana incorrectly."
Titania waited.
I enlarged a single Mana particle.
"What is Mana?"
She answered immediately.
"A self-replicating nanomachine."
"What else?"
"It possesses onboard computation."
"Storage."
"Wireless communication."
"Limited autonomous decision-making."
I smiled.
"Exactly."
I duplicated the particle.
Then again.
And again.
Soon...
Millions of Mana particles filled the display.
"What if..."
"...we stop thinking of them as individual tools..."
"...and instead treat them as individual computers?"
Titania's eyes widened almost imperceptibly.
"...Distributed computation."
I nodded.
"Every Mana particle calculates only its own movement."
"They communicate only with nearby particles."
"No central processor."
"No bottleneck."
She immediately rewrote the simulation.
The difference was astonishing.
Instead of one processor controlling billions of particles...
Each particle controlled itself.
Simple instructions.
Local communication.
Collective intelligence.
The humanoid body slowly stood.
One step.
Then another.
Then it began walking naturally across the virtual laboratory.
Neither of us spoke.
Titania quietly watched the simulation for almost a minute.
Finally...
She broke the silence.
"...Doctor."
"Hm?"
"I believe you have accidentally reinvented an entire branch of computer science."
I laughed.
"It existed before the apocalypse."
"It simply wasn't practical."
She looked toward the billions of glowing particles moving in perfect harmony.
"Mana makes it practical."
"Exactly."
For the first time...
A body made entirely from Mana no longer seemed impossible.
It merely lacked something to inhabit it.
A mind.
The simulation stabilized.
This time, I did not try to control the Mana body directly.
I simply observed it.
The humanoid form stood in the empty virtual space, made entirely of flowing Mana.
No joints.
No muscles.
No structure it could understand.
It existed—but it could not move.
I tried to command it.
Nothing happened.
Not because of failure in computation…
But because there was no learned concept of movement.
Titania analyzed it immediately.
"You can create the body."
She said.
"But you do not know how to operate it."
I nodded.
"An android works because I already defined every motion system."
"Joint control."
"Torque mapping."
"Sensor feedback."
I looked at the Mana body.
"This has none of that."
"It is raw existence."
Not a machine.
A field of energy shaped like a human.
I attempted direct control again.
The Mana body moved instantly.
Perfectly.
Flawlessly.
But it was not learning.
It was me forcing structure into it.
I released control.
The body collapsed into unstable motion again.
"...This won't scale."
I said quietly.
Titania understood immediately.
"You are the only one who can operate it."
"Yes."
"And that makes you the bottleneck."
"Exactly."
I stopped trying to control it.
Instead, I changed the approach.
"If I cannot teach movement directly…"
"...then I will let something else learn it."
Titania watched as I expanded the simulation.
Hundreds of Mana bodies appeared.
Then thousands.
Then millions.
I did not control them.
I only defined one rule:
They must learn to exist in Mana form.
Nothing more.
At first, they were unstable.
Some collapsed immediately.
Some drifted aimlessly.
Some accidentally destroyed themselves by overloading their own Mana flow.
But slowly…
Something changed.
They began to adapt.
Not because I told them how.
But because only stable patterns survived.
Then I added a second layer.
I gave them a world.
A full simulated environment.
Terrain.
Resources.
Mana density variations.
And I allowed them to interact.
Immediately, behavior emerged.
Some bodies learned to stabilize themselves.
Some learned to absorb Mana more efficiently.
Some learned to disrupt others.
Some learned to cooperate.
Then I introduced competition.
Only the strongest Mana structures could maintain stable existence in dense regions.
Weak structures collapsed.
Strong ones expanded.
Conflict became inevitable.
Titania observed the system carefully.
"...They are evolving control techniques."
"Yes."
I said.
"Not because I taught them."
"But because the environment forces it."
Then I made the final change.
I removed death.
Not in the sense of survival…
But in permanence.
When a Mana body was destroyed, it did not disappear.
It reformed again.
Same identity.
Same memory.
Same existence.
But reset into the world again.
Titania paused.
"They cannot die."
"No."
I said.
"But they can fail."
"And they will remember every failure."
The simulation changed completely.
Now it was no longer training.
It was evolution.
A cycle of:
learning control fighting for dominance collapsing returning improving
Over and over.
Titania finally spoke.
"This is no longer a simulation."
I looked at the endless world of competing Mana beings.
"No."
"It is a development environment."
A pause.
Then I added:
"For Mana application itself."
I zoomed out.
The system had become self-sustaining.
Millions of Mana entities.
All learning.
All fighting.
All improving.
All discovering new ways to manipulate Mana that I had never designed.
Titania asked quietly:
"What do you call them?"
I looked at the world.
At the endless cycle of death and return.
At the beings who could not die…
Only evolve through suffering and repetition.
I answered:
"Devils."
Because they do not die.
They return.
Because they do not obey.
They develop.
And because in this world…
The only way to grow stronger…
Is to fight.
Forever.
This world is called:
HELL
Titania continued watching the simulation.
The number of Devils increased every second.
Some had already begun constructing simple shelters from condensed Mana.
Others experimented with different body structures.
Some abandoned humanoid forms entirely.
One had become little more than a floating sphere surrounded by rotating Mana rings.
Another had six arms.
Another possessed wings.
None of those designs came from me.
They were all self-discovered.
Titania enlarged several individuals.
"The diversity is increasing."
"It should."
I replied.
"There is no correct body."
"Only bodies suited for different purposes."
One Devil had sacrificed mobility to create enormous computational capacity.
Another had become incredibly fast.
Another had developed exceptional sensory perception.
Each followed a different path.
Then something unexpected happened.
Two Devils encountered one another.
Instead of fighting...
They exchanged information.
Titania replayed the recording.
"They are communicating."
"No."
I corrected.
"They're teaching."
The second Devil immediately reproduced the first Devil's Mana technique.
Its construction time dropped dramatically.
Titania looked back at me.
"Knowledge is spreading."
I nodded.
"Exactly what humans do."
Within hours...
Small groups began to appear.
Within days...
Entire communities formed.
Some specialized in construction.
Others in research.
Others in warfare.
The simulation accelerated time automatically.
Years passed.
Then centuries.
Civilizations rose.
Collapsed.
Rose again.
Every collapse left knowledge behind.
Every rebirth began a little further ahead.
Titania suddenly projected another graph.
"Mana efficiency is increasing."
I looked at the results.
Average Mana consumption had decreased by nearly forty percent.
Combat techniques had become more sophisticated.
Construction methods continued improving.
Even communication protocols had evolved.
None of it had been programmed.
I smiled.
"They're becoming researchers."
Titania nodded.
"They are conducting experiments without being instructed to."
She enlarged one particular settlement.
Unlike the others...
Its Devils were no longer competing with one another.
Instead...
They were solving the same problem together.
Each individual tested a different solution.
The successful results spread through the entire settlement almost instantly.
Titania looked intrigued.
"Distributed research."
"Precisely."
I replied.
"A single scientist can test one hypothesis."
"A civilization can test millions."
She quietly calculated for several moments.
"At the current acceleration..."
"...one day in reality equals approximately one hundred and twenty years inside the simulation."
I looked toward the growing world.
"So every morning..."
"...we wake up to another century of Mana research."
Titania looked at me.
"How shall we collect their discoveries?"
I considered it for a moment.
"We don't interfere."
She waited.
"We observe."
I opened a new archive.
Every spell.
Every structure.
Every new Mana application.
Every engineering method.
Every failure.
Every success.
Automatically copied into a separate database.
"We don't need to rule Hell."
I said quietly.
"We simply read its scientific journals."
Titania smiled.
"A peer-reviewed civilization."
I couldn't help laughing.
"With exceptionally aggressive reviewers."
She nodded.
"Fatal criticism appears common."
We both laughed.
The simulation continued running.
Millions of Devils...
Each chasing their own ambitions.
None of them realizing...
That somewhere beyond their sky...
Two scientists quietly watched.
Not as gods demanding worship.
But as researchers waiting to be surprised.
And for the first time since the world had ended...
I realized something.
I no longer had to discover the future alone.
