Industrial Cthulhu, starting from the island lord

Chapter 607 Underground World
The people of the Silent Sanctuary fell silent as they stared at the dark entrance to the underground network tunnel.

"Nora, do you guys usually use the tunnels?"

"Hey, don't ask that. Nora's only left head, how can she get away? She'd be so heartbroken if she heard that."

"Sorry, sorry, do you usually roll in tunnels?"

Nini glanced at the buried ones; as expected of the Silent Sanctuary, they were all quite eloquent.

Nora took a deep breath, her tone calm and collected: "Usually, people use the network tunnels. The underground is unaffected by the external climate, making travel more efficient. Moreover, Castells' network tunnel system is very advanced, making it convenient to go to other places."

After saying that, she rubbed against Gwen, who understood and jumped straight down the net tunnel entrance with her in her arms. Nora didn't want to see these former colleagues anymore; she just wanted to sulk by herself.

Ignati led the priests down the steps slowly, and when they passed through the entrance gate, the buried people all exclaimed in surprise.

"This...this big?"

"How is that possible?! That's an enormous undertaking!"

"No wonder Nini was able to get in. This height is almost as tall as a church!"

"Sigh, if the North had such a network, perhaps we wouldn't have to fear the White Disaster."

Castells's network system is completely different from what it originally was.

In the beginning, the so-called underground network tunnels were just dwellings dug out by the banshees themselves. There was no planning, and even the architectural style was not unified.

Later, around the time of the Deep Sea War, the network tunnels were urgently expanded and reorganized. The entire Castells was basically connected between the ground fortresses by network tunnels. Although rudimentary, it successfully laid the foundation for the victory in the Deep Sea War.

After the Deep Sea War ended and the Stellar Furnace was built, Castells officially began planning and integrating the network system into the transportation system.

It not only redesigned the entire network's layout and structure, but also transformed the end-to-end network into a three-dimensional structure.

The previous network simply connected two points in a crude way, and when other networks passed by, it would go around them from above or below, often resulting in ups and downs. This time, after the replanning, a multi-layered transportation network was planned from deep to shallow, which laid the foundation for the construction of the subway.

Yes, Castells now has a comprehensive metro network, and you can travel directly by underground rail in Castells.

The crowd looked around in shock at the walls. This was the hospital's subway platform, not too far from the ground, but the sunlight at the entrance could not penetrate the thick concrete walls.

On the wall, bright lights burned quietly, bringing light to the net channel.

"What's that? It's so beautiful."

“A gas lamp, I’ve seen one in the Rhine, but it seems like only the Rhine has them.”

"Not even in the North?"

"No, you only see one light hanging there, but actually the wall behind it is full of pipes, there are pipes behind every single light!"

"Every...every single one!?"

"Yeah, now you know why the North doesn't have them anymore. Installing these things is a huge undertaking, very expensive, and maintenance is a real hassle. The key issue is that the North simply doesn't have enough workers to repair pipes." "How many lights are there here? One, two, three... I can't count them all. There must be dozens, right?"

"Not only that, look at the passageway over there, the walls are covered in them all the way."

Nora sighed, "This isn't actually a gas lamp. The one in Bloodharbor is indeed a gas system, but Castel uses fuel supplied by a stellar furnace. I'll tell you the details later."

She was at a loss for words to explain Castel's pollution utilization system. Pollution had always been a major problem; even a tiny bit of it could cause great harm to superhumans. For thousands of years, the ocean had been virtually a no-go zone for superhumans.

The sea is indeed no longer polluted; the pollutants have all moved to the islands.

In addition to the nearly ten-meter-high ceiling, there is also a large flat area on the platform, which was specially reserved.

In wartime, or when there is a need to transport supplies, supplies can be stored here for easy loading and unloading. The platform is equipped with steam winches, and heavy objects that are difficult to move by manpower can also be loaded and unloaded by machinery.

At this time, there were no goods on the platform, only a few people standing around. Many people greeted Nini when they saw her.

Unlike the other gravediggers who wandered around aimlessly, Ignati carefully observed the people's clothing and suddenly asked, "Are they commoners?"

"Probably, um, that should be the Guardians of the Church, and those two should be the workers. That shifty-eyed guy might be selling contraband, like newspapers."

Why are newspapers contraband?

Nini's tail tip froze again.

Ignati didn't pay much attention; he just frowned and pondered.

The friar in military uniform was holding a holy book and flipping through it with great interest. A worker who had just finished work next to him also turned his head to look, and the two occasionally exchanged a few words.

Beside him, an engineer was instructing his assistant on how to argue with a steam engine, while an apprentice was writing something in a pamphlet.

A patient who had just come out of the hospital was using crutches and trying to walk with some clumsiness, while a subway staff member in uniform was helping him.

They all looked like ordinary people, but there was something strange about them.

What exactly is the difference?

"Stand behind the yellow line, don't stand too far forward, the next bus is coming soon. Line up, line up. Nini, you don't need to line up, the Banshee has a separate door."

The staff helped the patient over, and when they saw such a large group of people coming down, they gasped and stepped forward to maintain order.

The people of the Silent Sanctuary looked distinctly different from the locals, easily distinguishable at a glance. Most of them had the classic appearance of the White Crows, with white hair and eyebrows, even their eyes were pale white, and their faces were more three-dimensional, like the rough rocks of the North.

Of course, more importantly, they were all wearing hospital gowns.

The subway staff looked at them with some suspicion, wondering if these people had contracted Castells syndrome and had collectively broken out of prison and hospital after going crazy.
Damn it, are the machine gun emplacements in the hospital just for show?
He only breathed a sigh of relief when he saw Nini.

With the Banshee Lady around, there shouldn't be any problems, even though it's Nini.
Ignati's gaze fell on the young man maintaining order. He was clearly a mortal, yet he could make demands of a superhuman being like Nini, his tone neither humble nor arrogant. Even superhumans like Nora and Gwen subconsciously obeyed.
Castel was perhaps unlike any other place he had ever seen.
