Chapter 227 Construction of an Underground City Beneath the Glacier (4K)

Given the tight schedule and heavy workload, V7 naturally did not linger and left in a hurry.

Before leaving, they left the Engineer with a large amount of underground city building materials and a set of construction drawings.

The location of polar underground cities is very important; they need to be in areas with stable ice layers and solid geological structures.

For example, the "dry valley" terrain unique to polar regions, characterized by extreme dryness, strong winds, and low temperatures, or the stable bedrock zone at the edge of an ice sheet.

This allows us to avoid active glaciers and reduce structural stress.

Engineering-based cities primarily rely on polar ground-penetrating radar vehicles, which scan ice/rock layers hundreds of meters underground to determine their stability. They also survey the vicinity for nearby groundwater and geothermal sources—allowing the underground city to utilize water and heat resources.

Overall, building underground cities in polar regions is more complicated than on ordinary land.

But there was nothing that could be done about it. After the silence agreement was abolished, there was no longer any binding force on the wasteland, which completely turned into a dark forest where the strong prey on the weak.

In such an environment, ordinary humans simply cannot survive on the ground.

After some investigation, the area for building the underground city cluster was finally determined.

Heath and Li Ye exchanged a brief greeting before leading their mobile urban warfare cluster into the sea.

In the coming period, he will lead his troops on patrols in the nearby waters to confront and annihilate any potential monster civilizations.

Both Liye and Heath dispatched reconnaissance aircraft.

According to reports from reconnaissance pilots, no monster civilization has been found in the area within hundreds of nautical miles.

The tundra region will remain peaceful for a while longer.

Li Ye felt relieved.

In that case, he can focus his energy on exploring the underground kingdom of the Spider Demon civilization.

Before that, Li Ye decided to go and see how the dungeon was constructed.

After installing the plasma tower left by Natural V7 and storing the building materials and construction vehicles, Zhou Xing ordered the Engineer to quickly head towards the construction site.

Joining in the fun, Li Ye arrived at the deck of the Engineer by helicopter.

“Zhou Xing, now that you’ve advanced to level 3, it’s time you considered recruiting more people,” he reminded him.

To date, the crew of the USS Engineer has a maximum population of around 3500.

The vast majority of them were mechanics and apprentices.

This makes its floor space seem extremely spacious.

Zhou Xing was taken aback, then gently shook his head.

The Engineer's population needs are far less than the Tomorrow's, and he doesn't share the same vision of building an urban society as Ryouno.

There was no insistence on leaving the field.

Upon arrival at the destination, Zhou Xing, referring to the design drawings, directed the engineer to begin engineering operations.

Its first task is to carve out a giant tunnel large enough for it to enter the underground.

As the plasma drilling tower on the deck of the Engineer was activated, a bright white ion beam pierced the ice cap like a lightsaber, instantly vaporizing to create a vertical channel 50 meters in diameter. The rising water vapor condensed into diamond dust in the sub-zero air.

The thick, cold ice layer turned into a piece of sugar that it quickly devoured.

Li Ye glanced at the design drawings in Zhou Xing's hand.

According to the plan, the underground city will cover an area of ​​approximately 4 square kilometers.

This is equivalent to 560 standard football fields.

It has only one floor and is divided into residential area, agricultural area, industrial production area, geothermal station, emergency shelter, water supply station and power station according to the plan.
After the initial excavation of the giant underground space, various engineering devices on the deck of the Engineer were activated to accelerate the excavation process.

Large and small robotic arms equipped with high-temperature torches simultaneously pierced the ice layer, and the blue-purple flames vaporized upon contact, creating a deep pit.

The working claws, equipped with serrated breaking pliers, successively probed into the pit, each bite scooping up ice blocks of various sizes and throwing them directly behind.

Cranes are used to lift the building materials to be used to various areas.

The robotic arm, located on the upper deck of the city, begins to weave the pressure-bearing underground city ceiling structure above the pit.

Combined with the continuing operation of the plasma drilling tower, the various engineering devices formed an elegant harmony.

During this period, the Engineer deployed a complete set of polar engineering vehicles.

The plasma ice drill bit emitted a faint blue arc of light as it pierced the ice cap, immediately causing a column of steam to rise from the underground space.

The modular tunnel boring machine, like a mechanical tapeworm, drills into the tunnel entrance, its resonant cutterhead at the front end pulverizing the permafrost layer at a frequency of two hundred times per second.

The multi-functional robotic arm engineering vehicle under the ice began to show its power, with multiple robotic arms dancing in dizzying trajectories under the dim ice cave.

In the icy, dust-filled air, the electrolytic cell of the air maintenance vehicle emitted a gurgling sound, like someone drowning. Like a steel behemoth suffering from asthma, it devoured the ice shards delivered by the crusher while spewing out oxygen from its exhaust vents—which was even mixed with fragrance, making it smell better.

Li Ye glanced at the design drawings, then at the tunnel boring machine.

According to the plan, these twelve underground cities are connected to each other by tunnels, and the means of transportation is a small-scale rail subway.

"The planning is quite detailed," he couldn't help but think.

Two days later, at the Ice Dome Research Base.

The exploration of the Spider Demon civilization's underground kingdom is about to begin.

Li Ye glanced at the system panel.

Meanwhile, an epic piece of intelligence has been updated.

6. The Spider Demon civilization's underground kingdom has spread throughout the entire Frozen Continent, covering a horizontal area of ​​764 million square kilometers and a maximum vertical depth of 15871 meters. The total number of Spider Demons is 12156261. Due to the remoteness of the tundra region, the Spider Demon civilization has undertaken relatively little construction there, but they already have expansion plans, intending to build tunnels, caves, and underground cities. (Intelligence Value: Epic)

Upon seeing the contents of the intelligence report, Li Ye was immediately stunned.

He knew the underground kingdom was vast, but he never imagined it would cover the entire continent.

The vertical depth of 15871 meters left him speechless.

"And a number in the tens of millions is quite a lot, isn't it?" he thought to himself.

What worries him more than this is the expansion of the Spider Demon civilization in the tundra region.

Humanity's underground city construction in the tundra region had only just begun, and they hadn't expected to run into trouble so soon.

The idea of ​​humans and spider demons living as neighbors is actually coming true.

As usual, Li Ye intentionally or unintentionally gave hints to the people at the research base, revealing information in the form of personal speculation and intuition.

He has always been very cautious about sharing and exchanging intelligence.

After listening to his story, Lin Mei immediately became interested.

“If that’s how it is, then it is indeed very interesting,” she said. “However, a monster civilization with tens of millions of members is not common.”

"Why do you say that?" Li Ye asked, puzzled.

Lin Mei told Li Ye that the monster civilization in the wasteland was at most between one million and several million in size.

A monster civilization with tens of millions of members is quite rare.

“Our research has revealed that the Spider Demon civilization has existed for over two hundred years,” she added. “This monster civilization is somewhat ancient and conservative, and not very willing to contact the outside world.”

Because of the remote location of the Frost Continent and the fact that its civilization was located underground, the Spider Demons were able to reproduce for a long time, eventually reaching a scale of tens of millions.

"Can the monsters still reproduce?" Li Ye wondered.

“They didn’t have it at first, but as time went on, the monsters evolved the ability to reproduce,” Lin Mei replied.

Li Ye's expression turned serious.

If they can reproduce, then aren't monsters pretty much the same as humans?
Then he slapped his forehead and remembered something.

Previous intelligence had mentioned the existence of an Emperor Monster in the Frozen Continent, but I forgot to share this information with the Ice Dome Research Base.

However, after hearing Li Ye's words, Lin Mei's eyes showed a hint of doubt.

"There are still Emperor-level monsters in the Frostbite Continent?" Li Ye was stunned, and his heart skipped a beat.

"The Titan Throne has deployed multiple research bases in the Frozen Arctic, yet they haven't discovered them yet?"

Lin Mei shook her head.

"No."

“I think there should be Emperor-level monsters in the Frostbite Continent. You’d better investigate further.” Li Ye carefully chose his words and said slowly.

Lin Mei couldn't help but smile.

She told Li Ye that although the Emperor Monster was enormous, it was not as easy to find as she had imagined.

They often dive into the ocean, soar through the sky, burrow underground, or even into the mantle to conceal their whereabouts.

Some imperial monsters would even carve out giant holes in the mountain peaks and crawl inside to hide.

Most importantly, the Monarch Monster can manipulate bio-fields to create a full-body camouflage.

Some imperial monsters can even evolve biofields, making them able to block the life signal tracking of scientific instruments.

"So do you understand now? Even if we wanted to, it would be very difficult to find the imperial monster you mentioned," Lin Mei said.

Li Ye nodded slowly.

The search for the Emperor Monster is now on hold; everyone should focus on exploring the underground kingdom.

When Li Ye thought about exploring the underground kingdom, he noticed a problem.

The operation is about to begin, but the batch of Level 0.5 mobile cities hasn't arrived yet.

At first, he thought the mobile cities were transported from Sky Island, but they weren't.

After learning of Li Ye's doubts, Oleg, who was standing nearby, offered an explanation.

The Ice Dome Research Base has a Level 3 resource transfer device and has also used energy-saving blueprints.

Normally, the base and headquarters use this device to transfer resources to each other.

"I see!" Li Ye suddenly realized.

A few minutes later, everyone received the notification.

The Titan Throne headquarters has prepared a level 0.5 mobile city and will be teleporting over now.

So, amidst everyone's expectant and excited gazes, the resource transfer device was activated.

A batch of Level 0.5 mobile cities thus emerged.

"Why are there only five?" Oleg seemed somewhat disappointed. "How can we possibly explore with just that many?"

Lin Mei, on the other hand, appeared much calmer.

Among the various research bases in the Arctic Continent, the Ice Dome is of average size, and the Spider Demon Tunnels, Caves, and Dungeons in the Tundra region are relatively few, so it receives far fewer resources.

“I heard that the largest research base is spread across 15 cities!” Oleg said with a hint of regret.

The Level 3 resource teleportation device cannot teleport living beings, so the drivers of the mobile city naturally did not come.

However, driving in a Level 0.5 city is much easier than driving in a Level 1 city.

According to one of the helmsmen, "Just drive it like you would a truck."

A level 0.5 mobile city is only a few dozen square meters in size. In order to facilitate travel through the underground tunnels of the Spider Demon civilization, the Titan Throne specially designed all the cities deployed to the Frozen Polar Continent to be long and narrow like trucks.

It's essentially a customized, special edition.

In fact, level 0.5 mobile cities are the most flexible.

It can be customized into various types according to needs.

An airship-type vessel that moves through the air.

A submarine-type vessel that swims underwater.

A racing car that speeds across the land.

A drilling rig that can flexibly move underground.

Engineering type that involves small-scale operations.

According to the Titan Throne plan, these five level 0.5 mobile cities were named Ice Dome A1-A5 in sequence.

Every city is at level 3 with full configuration.

3级火炮、3级重机枪、3级微型导弹发射装置、3级动力引擎、3级城市装甲、3级轮胎履带，再加上一系列3级攀爬装置和工程设备。

This makes them appear both small and sturdy.

However, due to the modifications made for these underground exploration missions, the internal structure of these cities no longer supports the "one city, one family" lifestyle.

The task of operating the mobile city to explore and fight deep into the underground kingdom is assigned to the special forces of Tomorrow.

A level 0.5 mobile city can carry 20 people, so 5 cities can carry 100 people.

During this period, I specifically observed the city's data.

Its dimensions are 12 meters long, 4.5 meters wide, and 3.5 meters high.

The unloaded capacity is 42 tons, and the maximum load is 57 tons.

Equipped with variable-gauge tracks for flexible rock climbing.

A sonic ground-penetrating radar capable of penetrating two kilometers of rock.

A laser spectrometer for real-time analysis of underground rock walls and geological mineral composition.

The city has an air suspension system.

The Titan Throne headquarters was extremely thoughtful, even deploying two tools specifically in each city.

The first is a complete set of Level 3 oxygen cylinders, breathing apparatus, and gas masks.

The second is a specially formulated spray developed specifically for spider demons.

In addition, each mobile city was equipped with cylindrical stakes, with various hooks installed on all four sides of the stakes.

This is to facilitate combat personnel in the city to secure themselves with hooks and engage in combat outside the city.

As for the special forces that cooperate with the city, they are armed to the teeth.

Level 3 assault rifle, Level 3 grenade launcher, Level 3 sniper rifle.

Level 3 hand grenade, Level 3 flashbang, Level 3 smoke grenade, Level 3 bayonet.

Level 3 jetpack, Level 3 camouflage combat uniform, Level 3 body armor, Level 3 bulletproof helmet.

A level 3 drone equipped with a light machine gun.

"Your special forces unit has a really good setup," Oleg remarked sincerely after seeing it.

With Li Ye and Lin Mei giving the order simultaneously, the exploration operation began.

Special forces members entered the level 0.5 mobile city in turn.

Their first task was to travel to a surface cave several tens of kilometers away.

The cave was dug by the spider demons and connects to an underground tunnel.

By entering through this underground tunnel, the mobile cities can delve into the underground transportation network of the Spider Demon civilization.

"Didn't you say that the Spider Demon civilization was a closed and conservative monster civilization? How come they would build tunnels leading to the surface?" Li Ye asked curiously.

Lin Mei, on the other hand, was concise and to the point.

"For the hunt."
