WorldCrafter - Building My Underground Kingdom-Chapter 219: Basement

Chapter 219: Basement

Unfortunately, Ben didn’t have the biological parts required to design a breeding species.

And with how complex the creation process had become, he’d need Elvira’s help to make it work.

There were a lot of things to consider, breeding methods, fail-safes, and especially population control.

Without strict limitations, he’d end up with too many mouths to feed and a massive strain on his biomass reserves.

“Forget that for now…” he muttered.

Then another idea came to him.

“Oh yeah… I can just use golems.”

He tapped his finger against the desk a few times, considering it.

That option was safer. Simpler. He still had a decent stockpile of white gems, and if anyone questioned it, he could easily claim he found them during the recent ruin expedition. It was a believable excuse.

‘Now I just need to design the recipe at the forge.’

Decision made, Ben stood up and left his office.

He made his way toward one of the abandoned noble mansions nearby.

With a flick of his wrist, he summoned his pickaxe. Thanfully even after losing the system, his inventory still worked. And he could still spawn building blocks directly around him as long as they were nearby.

Grinning slightly, Ben slammed the pickaxe into one of the column.

CRACK.

The pillar shattered into polished marble blocks, each one popping neatly into his inventory.

With no system there’re no more notification on what he got but it doesn’t matter anyway, since he know this is just another building material like grimslate.

He stepped forward and swung again, sending another support beam crumbling into resource chunks. It was oddly satisfying, every strike echoed through the halls, like a music to his ear.

He cleared the main floor first, flattening the entire mansion interior. Ornate stairs, velvet-lined walls, columns carved with noble emblems, he stripped it all down until only a bare 13×13 square remained. Smooth stone underfoot, open to the high cavern ceiling above.

He placed a hatch block in the center and hit it once. Clunk, it opened with a mechanical snap.

Ben stepped down into the new space, carving as he walked. With every swing of the pickaxe, the walls reshaped into clean-cut blocks. He descended ten layers, enough to put the facility out of easy detection range from above.

At the base, he started his real work. A clean, 30×30 square chamber. Each wall stood five blocks tall, reinforced with Grimslate, and layered on the inside with Grimslate Brick for added pressure resistance.

The lighting was subtle, glowstone shards placed every five blocks along the ceiling, giving a steady amber glow that shimmered off the stone.

Around the perimeter, he carved ventilation shafts, two-block wide tunnels placed every six blocks, leading to vents hidden along the surface.

In the far-right, he expanded the space into a 20×15 forging bay, large enough to hold four independent forges, each occupying a 4×4 space. They were spaced evenly in a line, with a one-block path separating them.

Each forge was surrounded by block-forged smelters, stacked two blocks high and four blocks long. They linked to an overhead rail system, connecting back to the resource intake near the elevator shaft. The rails weren’t fast, but they moved steadily, just enough to transfer materials between stations without needing direct supervision.

Across from the forges, Ben dug deeper, into a 15×15 block chamber, five blocks high, sealed behind a triple-layered security door. That was the biomass storage vault, it still haven’t completed as he need to install magic formation to regulate the temperature.

To the left of the central chamber, he carved out a housing barracks, a clean 10×20 rectangular hall, fitted with simple stone bunks, storage crates, and a teleportation box to deliver basic necessities like food. It was plain but functional, modular enough to expand easily if he ever needed to support a full battalion.

Finally, at the rear, he created the Command Core, an elevated 7×7 square platform with railings, overlooking the rest of the facility. He left space behind it for stairs that would later lead even deeper if he chose to expand.

Here, he placed a reinforced stone chair, a table made of crystal, and an embedded mana sensor into the floor, ready to connect with Elvira’s magic formation when she have the time to work on it.

Ben stood at the center of it all, hands on his hips, surveying the finished base.

“The rest is up to Elvira. If she can expand the magic circuit through the entire city… we’ll get real-time holographic projection next.”

It was a massive project, but the result would be worth it. With this system in place, the city’s security would increase many times over.

Every crime could be detected instantly. If Elvira managed to recreate a working magical computer, especially one with basic AI capabilities, they could even eavesdrop on conversations, track movement patterns, and mark high-risk individuals automatically.

Ben let out a chuckle.

“If I were a civilian, I’d riot the moment I heard about this.”

He remembered reading old novels about dystopian police states, where citizens were monitored 24/7. Sure, crime was nearly gone, but the price was rampant abuse of power and mass arrests for things as small as public complaints.

But in this case?

He wasn’t worried.

He was the one on top.

“Apophis would definitely call me a hypocrite if she were here,” he muttered with a smirk. freewebnσvel.cѳm

He created four Krell Scouts, two assigned to maintain the base, and the other two set to start digging tunnels back toward the city.

He didn’t make more yet, he hadn’t finalized the tunnel blueprint or calculated the logistics. He also hadn’t stocked enough food or water for an expanded crew.

Sure, he could just transfer supplies himself through his inventory… but honestly?

He couldn’t be bothered right now. There were still too many other tasks on his plate.

With the forge completed, Ben made his way back to the surface. The next job was to rebuild the mansion above it, but this time, to his tastes. It wasn’t about defense or function now. It was personal. A leisure project.

“Hmm… I’ll need a lab like Elvira’s too,” he mused, stretching his arms.

“Something to study biology… and a personal workshop. Might as well start experimenting on stuff myself.”
