Lucien spent the next stretch of days doing something he found deeply satisfying.

He buried Spirit Mountains.

He stood over one of the deeper sectors beneath Lootwell’s greater territory and looked down through layers of opened earth, law-cut bedrock, and prepared channels where dozens of Spirit Mountains now rested below the ground like sleeping titans hidden beneath the skin of the world.

He had gathered them over the years.

Some had come from the ruin expedition. Many from the resource sites. Some were taken from the enemies.

Individually, they were treasures.

Collectively, they were not enough.

Lucien had already understood the scale of his problem.

He governed a population spread across worlds and territories so vast that old methods of counting had begun feeling insulting.

He had more than ten billion people under him now.

Against that scale, even abundance looked temporary if it was not turned into a system.

So he planted mountains into the deep foundation of the land and began shaping the world around them.

The placement was not random.

Spirit veins were sensitive things. They did not merely sit where one buried resources and obediently produce more. They responded to pressure, ley-line direction, elemental balance, earth stability, surrounding mana saturation, and whether the local world-law would accept accelerated spiritual density or begin rupturing under it.

Lucien considered all of that.

He layered formations over the buried mountains one after another.

Some drew ambient energy downward and compressed it. Some regulated pressure so the developing veins would not become violent. Some purified harmful distortion from the intake. Some encouraged branching so the mountains would not remain isolated deposits, but become the hearts of future spirit-vein networks spreading outward into surrounding stone.

By the time he finished, the entire underground sector looked like a hidden celestial diagram carved beneath the territory.

The first pulses of resonance had already begun.

It would not take long.

Soon enough, naturalized spirit veins would begin producing mineable spirit crystal, and once that process stabilized, Lootwell would no longer depend only on old stores and salvaged resource caches.

It would begin generating its own wealth beneath its feet.

That alone pleased him.

The next question was simpler.

Who would mine it?

He made a note to speak with the right divisions later.

Then his thoughts moved on.

Because spirit veins were only one part of what a territory like his needed.

The next part—

was dungeons.

The dungeons in the small worlds had begun approaching the end of their natural usefulness.

Lucien already knew that.

Those dungeons had formed as scars where monster invasions wounded the worlds. They existed because there had once been an active hostile pressure from outside. But now the situation had changed. No new invasions were feeding them.

Over time, if left alone, those old dungeons would simply weaken, collapse, and disappear.

For most people, that might have sounded like good news.

To Lucien, it sounded like waste.

So he salvaged them.

The dungeon cores.

He let the dungeons themselves collapse after securing their hearts.

The dungeon cores fascinated him immediately.

They were beautiful in the infuriating way that only deeply functional design became beautiful once someone competent understood what they were looking at.

At first glance, they were only crystalline hearts of scar-logic. At deeper inspection, they were much more.

They recorded identity.

That was the key.

The world had not merely been wounded by monsters. The world had remembered what wounded it. The core had taken that remembered foreignness and organized it.

It categorized invasive beings the way a healthy body might categorize a pathogen. Not simply as "monster," but as structured hostile signatures marked by trait, pattern, resonance, behavior, and relation to the scar that birthed the dungeon.

Lucien saw it all through Structural Insight and nearly laughed in appreciation.

The Primordial Slime had been absurdly meticulous.

This was supposed to be just a scar.

And yet the scar functioned like an archivist, a filter, a world-response mechanism, and a recycling chamber all at once.

That realization changed everything.

Because it meant Lucien did not need to design monsters from nothing.

He did not need to invent foreign identities manually or build each hostile print by hand.

The cores already held the world’s own recorded impression of the invaders.

He only needed to learn how to preserve those records, cleanly re-express them, and feed the system enough fuel to keep producing stable dungeon entities.

That last part mattered.

A dungeon could not function on category alone.

It needed essence.

And for that, Lucien already had answers.

He had the Gargoyle Ancestor.

He had Kharzun.

He had the Voidwalker he and Eirene had faced in the first resource site.

Three major fuel sources alone were enough to sustain lower dungeons for years if managed properly, especially if the resulting systems recycled well.

Lucien felt no pity on that point.

If their essence was eventually used up, then that was only justice being translated into public utility.

Still, he knew it would not be enough forever.

If he wanted the deadliest environments and deeper training structures later, he would need more fuel sources.

That thought did not trouble him much.

The world produced villains constantly.

He would simply become more efficient about gathering them.

•••

That day, Lucien started building.

He did not rush.

He gave the dungeon creation the kind of attention an artist, engineer, and warlord might all agree was correct.

He studied the cores first.

Then he adjusted them.

Then he studied how to adjust them without ruining the native logic that made them so elegant to begin with.

He learned where the identity-records sat. Where the world-markings were strongest. Where monster expression could be altered without collapsing authenticity. Where the dungeon’s recycling process could be sped up. Where safety restraints needed to be added if the dungeon was to serve as a training structure rather than a random massacre engine.

He considered everything.

How quickly should monsters respawn? How much essence should each floor be allowed to spend at once? How realistic should the environmental simulation become?

Should dungeon monsters possess full beast cores? No. That was a bad idea.

Should they develop true personhood if fed enough essence over time? Absolutely not, not for a training dungeon. 𝗳𝗿𝐞𝕖𝘄𝗲𝕓𝗻𝚘𝚟𝕖𝐥.𝚌𝕠𝕞

Should leaving be possible from every floor? Yes, but not too easily.

Should trainees be able to bypass floors without clearing them? Only under controlled route permissions.

Should the monster behavior reflect natural habitat instincts? Yes. Completely.

That last one mattered.

He did not want cardboard enemies wearing monster skins.

He wanted people to learn how real monsters behaved in terrain that favored them.

So he modeled every floor according to Monsterdex records and environmental truths.

If a species hunted best in wet darkness, it received wet darkness. If it used broken elevation and blind angles, the floor gave it cliffs, crevices, and unstable stone. If it relied on swarm movement, the floor’s structure had to support coordinated pressure rather than open-field stupidity.

And because Lucien was Lucien, he kept improving while building.

One of his biggest breakthroughs came from understanding the dungeon monsters themselves.

They were not true living creatures.

That was by design.

He had no interest in building intelligence only to turn it into slaughter practice for his people and then demand they live with that guilt.

So he shaped the system differently.

Dungeon monsters would carry behavioral identity, environmental instinct, combat rhythm, and ecological expression.

But they would not carry a true self.

They would be simulations given lawful hostility.

When killed, they would dissolve. Their essence would return to the core. The dungeon would recycle the essence and produce more.

Except, of course, for Lucien and his pets.

His cheats were still connected to them.

If his pets killed dungeon monsters, the essence trying to return to the dungeon system could instead be intercepted by the drop-conversion structure linked to them.

Which meant the dungeon had accidentally become a supplementary drop farm.

Lucien stood in the half-built tower when he realized that and smiled in a way that would have worried more ethical men.

•••

A full month passed in that work.

By the time he finally emerged from the most obsessive stage of construction, the territory had already started calling the structure something on its own.

Not because Lucien announced a grand name.

Because people had seen it.

And no one who saw it remained normal about it.

The tower rose from the training grounds like a vertical trial carved against the sky. Floor after floor climbed upward in narrowing dominance. Its silhouette was so high and severe that the upper sections often vanished into cloud and ward-light depending on the hour.

It was not beautiful in the graceful sense.

It was imposing.

After hearing several increasingly ridiculous suggestions, Lucien settled on the name himself.

The Ascension Spire.

This was a tower built to force upward movement.

Each floor held a different theme. A different ecology. A different monster set. A different tactical lesson.

The lower levels dealt with predator awareness, swarm pressure, terrain reading, retreat discipline, and coordinated monster behavior.

Higher levels would one day handle much worse.

For now, however, the usable floors remained limited.

The structure itself had reached one hundred floors thanks to the help of Anvil-Horn and the others.

But fully powered floors?

Only around a dozen.

Fuel remained the bottleneck.

Lucien had enough essence sources to populate lower training levels reliably. Those floors could currently train fighters up to around the Third Stage of Transcendence with serious effectiveness.

That was already more than enough to shake the territory.

But it was not enough to satisfy him.

The highest chamber of the tower held the fuel sources themselves, sealed in controlled extraction formations. They were still unconscious and never fully aware of what they had become.

All of them now powered the thing they would have hated most.

A system that made Lucien’s people stronger.

When the first testing cycle began, Lucien invited select trainees in.

He did not open the entire tower at once.

Instead, representative groups entered with supervision.

The response was immediate.

The monsters were stronger than expected.

Not because their raw power was outrageous. Because they behaved correctly.

They did not stand in convenient places and die. They moved through their own environments with predatory advantage. They used ambush angles, pressure routes, terrain memory, and species instinct in ways that made ordinary training look childish by comparison.

That alone made the tower worth the effort.

The trainees returned bruised, exhilarated, and louder than before.

The main complaint was almost flattering.

The middle and upper floors were not ready yet.

But Lucien had already accounted for safe withdrawal.

Each floor contained a linked teleportation array that could send trainees back to the ground level if they chose to leave or if emergency conditions triggered supervisory override. He had no intention of letting the tower become a vanity project that killed people carelessly just because they wanted to prove bravery to themselves.

By the end of the first full trial period, the conclusion was obvious.

The Ascension Spire worked.

Lucien stood looking up at the Ascension Spire from the training grounds while the evening wind moved quietly around him.

Behind him, he could hear new trainees arguing over floor strategies as if the tower had already become part of ordinary life.

That pleased him.

Very much.

He smiled faintly.

Then he made another note in his mind.

More fuel.

More floors.

The world was too full of bad people for him to ever let a resource shortage remain a long-term problem.
