Mobile City Farming Guide

Chapter 228 Exploring the Spider Demon Kingdom (4K)

Spider demons are used to staying underground for long periods of time, but they also frequently come to the surface to hunt.

The targets of their hunts are monsters, mutated creatures, and even humans from various regions of the Arctic.

Spider demons also possess powerful diving abilities and sometimes hunt in the sea.

They rely on the hunting silk secreted by their own spiders.

Once prey gets entangled in these spider webs, it is often difficult for them to escape.

The level 0.5 mobile city moved very fast, almost at breakneck speed, and soon arrived at the cave.

They lined up in a long queue and drove in one by one.

Cameras have been installed throughout the city for easier observation.

Those located in the research base could see the scene inside the tunnel and the various instrument screens inside the mobile city through the screens in various places.

Viscous, deep.

The spider demons' tunnels appear to have been created through a process of half-digging and half-corrosion.

According to Lin Mei's speculation.

The spider demons first used highly corrosive acid-corroding spider silk to dissolve the rock layers, then used their steel-hard limbs to scrape out smooth curved surfaces, and finally used load-bearing spider silk to reinforce the structure.

A dozen minutes later, the mobile cities arrived at a large, empty space.

This is clearly a node in the tunnel network of the Spider Demon civilization.

It resembles a deformed beehive, where countless tunnels converge, split, and twist, forming an intricate three-dimensional maze.

Standing at the center of such a point feels like the confluence of the blood vessels of an underground behemoth.

Every tunnel leads to an unknown destiny.

And in the depths of darkness, it seems as if some being is silently watching you.

The air grew heavy and oppressive without us even noticing, and even breathing felt cold and damp.

The echoes coming from the distant tunnels made it impossible to tell whether they were the sound of the wind or not.
Or perhaps it's the breathing of some kind of creature.

"Professor Lin, where should they go next?" Li Ye asked instinctively.

"Don't be too nervous," Lin Mei replied. "The first exploration doesn't need to be in-depth; a rough survey will suffice."

Under her command, the five level 0.5 mobile cities began to move forward.

The installation of Level 3 climbing accessories in the city has begun, and they are shaped like spider limbs several meters long.

The mobile cities nimbly climbed the rock walls like spiders, entering their respective tunnels.

Just then, beeping sounds suddenly rang out inside the five mobile cities.

"What's going on, Professor Lin?" Li Ye asked.

“That’s the alarm sound the device makes when it detects metal,” Lin Mei replied. “Clearly, there are magnetic spiderwebs at this tunnel node.”

She then ordered special forces to begin scouting for spiderwebs near the tunnel.

Soon, the special forces members discovered the magnetic spider silk.

It is not as slightly transparent as spider silk in nature, but more like a liquid galaxy forcibly solidified into a line.

The magnetic spider silk floats discreetly within the tunnel, not extending in a straight line, but rotating slowly in a spiral shape as if it were alive.

Lin Mei's expression gradually became serious.

"In fact, the spider demons have already sensed our arrival through the magnetic spider silk."

"what did you say?"

Li Ye was momentarily stunned.

Was a level 0.5 mobile city discovered so quickly?

Lin Mei then instructed a special forces member to slowly bring the weapon close to several nearby magnetic spider silk threads.

As the guns approached, the magnetic spider silk suddenly taut into sharp zigzag lines, transmitting waves of energy far away.

“Did you see that? The moment the mobile city entered the tunnel node, the magnetic spider silk deployed here reacted and transmitted fluctuations,” Lin Mei said. “And the spider demons will soon sense these fluctuations and realize that enemy vehicles have arrived.”

Li Ye shook his head helplessly.

The spider demons' arrangement was simply impossible to defend against.

The underground is their natural habitat, and humans must rely on metal tools and vehicles to enter and explore it.

Lin Mei then asked the members to test the power of the magnetic spider silk.

According to the other party's report, he felt a faint magnetic force when he was 10-20 centimeters away from the magnetic spider web.

As the distance gradually decreased, the magnetic spider silk eventually adhered firmly to the firearm.

"Is the magnetic force really that strong?" Li Ye asked in surprise.

Immediately afterwards, a hint of emotion appeared in his eyes.

It must be said that the spider demons' methods of evolution are truly ingenious.

Instead of striving to strengthen themselves, they have evolved various similar spider silks.

Combined with the terrain in which their own civilization lived, they formed a subtle constraint on humanity.

Magnetic spider silk alone can effectively restrain vehicles and firearms that humans deploy in underground spaces.

Not to mention other special spider silk.

"In the wasteland, high-level monster civilizations often have their own ways of surviving," Lin Mei concluded.

"So, does the Spider Demon civilization belong to the Chosen Ones? Professor Lin," Li Ye asked.

Lin Mei gently shook her head.

"I'm not sure about that. However, in past encounters, Tianze hasn't deployed any forces against the Spider Demons, nor have they used the spider silk produced by them, so they probably haven't joined Tianze," she replied. "Furthermore, Tianze's selection process for monster civilizations is extremely rigorous, often using combat strength as the evaluation criterion, so..."

"Oh"

Li Ye nodded slowly.

He understood what Lin Mei meant.

In the eyes of Tianze, a world-class organization composed of a highly evolved monster civilization, the Spider Demon civilization's evolution might not be up to par.

Especially on the ground, the Spider Demon civilization's combat effectiveness is greatly reduced.

They have no vehicles, no mobile cities; at best, they can only serve as cannon fodder.

After the exchange ended, everyone continued watching the screen.

Upon closer inspection, everyone discovered that the five mobile cities were covered with numerous magnetic spider webs.

Lin Mei immediately ordered the special forces to handle the situation promptly.

The magnetic spider silk removed from the city was not thrown away, but she insisted on keeping it carefully so that it could be taken back to the research base.

Just then, an alarm sounded inside Dome A3.

The special forces members looked toward the radar following the sound and spotted a red dot ahead.

However, when Ice Dome A3 shone its searchlights in front of it, it found nothing but emptiness.

"The radar doesn't make mistakes; there really is a spider demon lurking there, waiting to attack you."

Lin Mei said.

"It has camouflaged its entire body with camouflage spider silk!" Under her instructions, several special forces members quietly arrived outside the city, secured themselves with hooks, and took their positions in front of artillery, heavy machine guns, and light missile launchers.

"On my command, fire all at once after the countdown ends," Lin Mei whispered. "Five, four, three, two, one!"

As the countdown ended, Ice Dome A3 unleashed a barrage of firepower forward.

Under the bombardment of the level 3 artillery, the spider demon's carapace burst into dazzling fireballs, and shrapnel and shockwaves tore the rock walls to shreds, with debris raining down on it.

The spider demon let out a deafening shriek, a sound like a mixture of twisting metal and the wailing of a baby, creating a terrifying sonic boom.

The machine guns followed suit, firing in a long, crimson whip as armor-piercing rounds pierced the spider demon's body, leaving gaping holes the size of bowls. Its steel-like carapace finally gave way, exploding with a sickening cracking sound.

The spider demon's body was almost torn apart, but it still struggled to charge forward, leaving a long trail of slime behind its severed body.

A special forces member immediately picked up a grenade launcher and fired a high-explosive grenade at him.

As the high-explosive grenade hit and exploded, the spider demon's remains were engulfed in flames. Its bodily fluids boiled and evaporated in the high temperature, and its body twisted and deformed in the flames.

Its final struggle smashed a huge crack in the tunnel wall, and rubble and dust poured down like a waterfall.

As the explosion and smoke gradually dissipated, only a charred wreckage remained, still twitching.

Upon seeing this, Oleg put his hands on his hips and let out a long sigh of relief.

"It seems the battle was relatively easy."

Li Ye's focus is completely different from his.

"Are we safe now? Go check what this spider demon dropped."

After the battle, the entire tunnel was on the verge of collapse and had many cave-ins and broken holes.

But with his jetpack and climbing claw, a special forces member easily reached the vicinity of the spider demon's corpse.

22单位3级铁矿，15单位3级布料，72枚晶币。

Upon hearing the member's report, a hint of surprise appeared in Li Ye's eyes.

"The drop rate is acceptable."

But compared to the giants, they were ultimately still a little lacking.

With the danger averted, Ice Dome A3 changed to another tunnel and continued its exploration.

The public's attention gradually expanded as they explored the five Level 0.5 mobile cities separately.

The searchlights of the mobile city appeared minuscule in the tunnels constructed by the spider demons. The tunnel walls were no longer rough rock, but covered with a layer of viscous black liquid, even containing vesicles. As the city's mechanical limbs rolled over this liquid, they produced unsettling, sticky sounds.

As Li Ye watched, a look of surprise appeared in his eyes.

"Is this... a fungal carpet?"

“Yes,” Lin Mei replied. “Like the insectoids, spider demons also possess the ability to secrete fungal carpets.”

She gave a brief explanation of the science.

The fungal carpet secreted by the spider demon is "custom-made for the underground world" and has three main functions.

First, the mycelium in the fungal carpet can combine with the minerals in the tunnel walls to slowly repair the tunnel gaps.

Secondly, the fungal carpet can absorb carbon dioxide to produce oxygen and filter toxic gases. It can store geothermal heat in winter and cool down in summer, thus maintaining a constant temperature in tunnels, caves, and even underground cities.

Third, the hyphae contain biofluorescent proteins that can emit cold light through chemical reactions, thus providing illumination in the underground world.

"The fungal mats are actually a very nutritious food and can be eaten directly," Oleg added.

Li Ye's expression became unnatural.

The thought of insects crawling on the fungal carpet made him feel nauseous, let alone eat it.

A few seconds later, Ice Dome A4 detected the anomaly.

As it was about to enter a tunnel, loud alarms sounded from inside the city.

This is also the sound emitted when the device detects metal.

There is no doubt that there is something fishy about the tunnel in front of us.

After careful investigation, everyone finally understood the reason.

The entire tunnel is covered with countless magnetic spider silks.

Under their influence, the tunnel acquired tremendous magnetic force and even began to attract Dome A4.

Lin Mei immediately ordered Ice Dome A4 to reverse at full speed.

“This is a trap tunnel specially set up by the spider demons. Once a vehicle is sucked in, it will be completely trapped,” she said.

Ice Dome A5 also encountered a dangerous situation.

The tunnel it entered contained a large amount of acid-corroding spider silk. By the time the mobile city entered the tunnel, the mechanical limbs had already been corroded by more than half without anyone noticing.

Fortunately, the mechanical limbs were equipped with sensors, which immediately sounded an alarm throughout the city upon detecting the damage.

The sound was even louder than when the magnetic spider silk was detected.

Ice Dome A5 quickly withdrew from the tunnel and entered a nearby tunnel.

Each mobile city is equipped with spare mechanical limbs in order to avoid such situations.

Through the screen, everyone saw the replaced mechanical limbs.

Dozens of acid-corroded spider silks clung tightly to it like maggots rotting bones.

The entire mechanical limb emitted a dying groan. The once intricate gears and components were twisted and deformed by the erosion and gnawing of the spider silk, crumbling one by one. Lubricating oil seeped from the rotten pipes, mixing with acid to form a viscous, bubbling black pus.

The corrosion spread extremely quickly, and soon the circuit boards of the mechanical limbs were completely eroded away. The integrated circuits began to bubble with green foam, curled up and peeled off, and finally melted into a pool of semi-solid metal mud.

All the mechanical joints were thus rendered unusable.

Upon witnessing this scene, everyone broke out in a cold sweat.

The trap set by the spider demons was truly terrifying.

If Dome A5 had been just a few seconds later, its mechanical limbs would have been completely destroyed, and the entire mobile city would have been gradually "melted" inside the tunnel.

If an ordinary creature were to accidentally step in, it would be entangled by the suddenly triggered acid-corroding spider silk and melt into a pile of liquid in a short time.

“This trap is utterly illogical,” one researcher said, his voice trembling. “At least magnetic spider silk can be detected, but this is completely undetectable.”

Special forces members then began urgently replacing the old mechanical limbs.

The people watching on the screen became extremely nervous.

For mobile cities, losing mobility is extremely dangerous, even in the underground world.

As if things weren't going to go wrong, alarms sounded again throughout the city.

It was even louder than when magnetic spider silk and arthropod wear were detected before.

The city's radar detected three red dots approaching from a distance.

It was clear that the three spider demons had sensed the commotion and rushed along the tunnel.

"How much longer will it take you to replace the mechanical limbs?" Li Ye asked urgently.

“It will take about 5 more minutes,” a special forces member replied.

Li Ye couldn't help but shake his head.

Judging from the speed at which the red dot on the radar moves, the three spider demons will arrive at the tunnel within 2 minutes.

"It's too late. Prepare for battle," he said in a deep voice.
