Mobile City Farming Guide

Chapter 370 Space Defense Line (4K)

All you need to do is follow the path the Star Eater takes, find a planet that meets the requirements, and transform it into a planetary cannon.

As for what the planet will look like after it ignites—that's not a question that humanity should care about at all.

After being reminded by the leader, everyone instantly became excited.

"Even if we can find a planet that meets the conditions for terraforming, the sheer scale of the project is staggering," Li Ye hesitated, then stopped speaking.

"Don't worry, there are a large number of engineer-type mobile cities stationed on Fireseed Star, which can meet the engineering needs," a high-ranking official replied.

After discussion among the group, a new battle plan was born.

The project is called "Space Defense Line".

Humanity will deploy a large number of engineer-type mobile cities to transform the asteroid belt, comets, and dense meteorite belts along the way into a vast buffer zone in order to slow down the advance of the star-eating beings.

As for the Tomorrow Alliance, they will be responsible for fighting the Star Eaters.

"Time is of the essence, let's start preparing now," the leading executive said.

Two completely different scenes immediately appeared on the planet Fireseed.

On one side, groups of people carrying hastily packed luggage lined up to board the mobile city for refuge, guided by staff.

On the other side are neatly arranged, massive mobile cities of various levels, designed for engineering purposes, heading towards space.

At this very moment, Tomorrow Alliance has already traveled into space.

Li Ye arrived at the production workshop and began investing resources to build vehicles.

One MA-Ghanaku 09 space combat vessel, four "Starburst" space combat cruisers, and two level 6 gravitational wave controllers.

The Level 1 mobile cities Starship and Awakening in the Tomorrow Alliance will each be equipped with a gravitational wave controller.

The former is responsible for fighting the Star Eaters, while the latter works alongside the engineer-type cities to construct the "space defense line."

With Novi's help, he found the best location in space to confront the Star Eaters and ordered the Tomorrow Alliance to set off.

When Li Ye woke up, Tomorrow Alliance had already arrived at their destination.

Meanwhile, the engineer-type mobile cities are also ready and are systematically beginning to build space defense lines under the command and coordination of the human leadership.

The first batch of engineer-type mobile cities has arrived in the asteroid belt.

This is a vast, almost silent region, scattered with countless planetary debris and rock formations.

Some rock formations are only a few meters in size, while others are thousands of meters in size.

This batch of engineer-type mobile cities are all level 0.5 and level 1. They skillfully cling to those rock formations hundreds of meters high and begin "terrain surgery".

Robotic arms, working claws, and cranes were activated in sequence on the city's engineering equipment. Some cut through deep trenches to lay pipelines, some leveled huge platforms to install thruster bases, and some drilled vertical shafts that led directly to the core of the rock mass.

Once all this work was completed, the mobile cities began laying energy lines, installing thrusters, and mounting composite armor plates with ramming horns along the rugged rock surface.

In this way, the rock mass was transformed into a high-powered space pebble with sharp angles, driven by thrusters.

The second batch of engineer-type mobile cities was responsible for transforming the comet into a "minefield".

They selected icy comets in space and implanted huge pressure vessels inside them.

The container contains ultra-low temperature solidified gases such as methane and nitrogen, as well as highly abrasive metal dust.

As the Star Eater approaches, the Ice Comets are remotely detonated, creating vast, extremely cold clouds of solidified mist. These clouds can freeze the mechanical devices on its body, block energy transmission, and weaken mechanical efficiency.

The third batch of engineer-type mobile cities is responsible for creating high-density asteroid belts.

They transport and gather meteorites of various sizes scattered in space, then activate the gravity device to transform them into a giant meteorite vortex.

As for the fourth batch of engineer-type mobile cities, they are responsible for the most magnificent project in the defense line—the planetary cannon.

Following the route of the impending invasion of the planet-eaters, humanity actually discovered a planet that met the criteria.

It was a rocky planet located 3529 kilometers away from the planet Mars.

Its geological structure is rich in metals, has a high density, and a relatively thin mantle.

The number of engineer-type cities used to terraform rocky planets accounts for more than 50% of the total.

The first three batches of engineer-type mobile cities will also come to help after completing their own tasks.

Under the command of the human leadership, hundreds of mobile engineering cities of varying sizes descended upon the rocky planet.

Each of them performed its own function, progressing step by step, thus beginning the massive construction project of the planetary cannon.

Multiple Level 4 mobile cities have been positioned at the equator and poles of the rocky planet to begin construction of a joint gravitational anchoring matrix, which will be used to launch gravitational beams toward the planet's core to stabilize its rotation and revolution.

Hundreds of Level 0.5 and Level 1 mobile cities landed on the planet's surface, activating rotary drills and thermal cutters to strip, crush, and grab large swaths of rock layers, blocks, and veins from the planet's surface.

The Level 2 mobile city hovers at low altitude, lowering a magnetic grab bucket and a gravity-adhesive boom that are hundreds of meters long to pick up the rocks and veins excavated by its companions and dispose of them.

Over time, the rocky planet was peeled away layer by layer at a visible rate, revealing its scorching, dark red iron-nickel core.

Level 3 mobile cities lined up in an array, extending countless high-temperature resistant gravity-sensing claws that plunged into this molten metal ocean.

With the aid of the gravitational anchor matrix device, the Level 3 mobile city began to be guided, stretched, and shaped in the metal ocean, forcibly casting a hollow metal column that runs through the planet's poles in the core—this is the barrel of the planetary cannon.

As the main body of the gun barrel gradually solidifies and takes shape, the next steps are the laying of superconducting coils, the welding of structural reinforcement beams, and the riveting of armor plates.

The Level 4 mobile city hoisted the newly built, mountain-sized energy capacitor module and thruster array, and with the assistance and guidance of other mobile cities, completed the final hoisting and docking.

The entire process lasted two full days, and by the time the mobile cities finished, the planetary cannon was already complete.

"This engineering capability is truly impressive!" Li Ye couldn't help but exclaim.

Over the course of those two days, he would occasionally have Novie pull up construction footage of the rocky planet to watch.

To Li Ye's surprise, the higher-ups on Fireseed Star actually granted him the authority to launch the planetary cannon.

"You will be free to decide when to fire this planetary cannon," the high-ranking officials solemnly told Li Ye.

Li Ye nodded.

The trust everyone placed in him put him under immense pressure.

On the other hand, the development of Tomorrow Alliance vehicles has also been completed.

The space combat MA "Ghanaku 09" and the Starlight Space Cruiser are ready.

Li Ye couldn't help but glance at the system panel.

[1 days, 13 hours, 59 minutes, and 59 seconds until the next intelligence update]

[Number of intelligence reports: 7]

This time, the intelligence update will take a total of 7 days, and the quality should be very high.

After the Star Eater incident is over, he will decide the future direction of the Tomorrow Alliance based on the intelligence gathered.

With everything prepared, humanity quietly awaited the arrival of the enemy.

Time seemed to slow down dramatically. When Rino awoke again, Novi's image appeared before him.

"Master, he is coming."

Li Ye nodded solemnly.

"Ah."

The camera shifts to the distant, silent depths of space.

The enormous, deep silhouette began to slowly emerge.

The first thing that came into view was a deep blue, incredibly complex mechanical ring, with its intricate geometric structure slowly rotating—it was a ring-shaped mechanical crown.

Beneath the crown, a huge, ancient, indifferent, and imposing face gradually appeared.

Tens of thousands of energy lines extend from the thick mechanical armor, gleaming with a violent flow of energy so bright it could burn the retina, illuminating the space in a ghastly white light.

The rotating star rings beneath his feet are fully revealed, silently tearing through spacetime and generating a powerful gravitational field so that his master can slowly "move" through space.

Upon seeing the Star Eater appear, the members of Tomorrow's Alliance couldn't help but breathe in unison, their hearts stopping.

Although everyone had anticipated this, they were still shocked when they saw the true face and figure of the Star Eater.

“Wow, it’s huge,” Fang Yong couldn’t help but say.

Given the Star Eater's size, it could easily grab the Level 6 Tomorrow with just one hand.

Whether it's space fighters, space cruisers, super mobile suits, or even mobile armor and mobile cities, the combat forces of the Tomorrow Alliance are as insignificant as dust in his eyes.

For a moment, everyone was somewhat uneasy.

After all, humans are born with a fear of giant objects. And the Star Eaters are beings from outer space, comparable in size to planets.

Li Ye waved his hand, signaling everyone to calm down.

He looked at the data displayed on the handheld computer.

[Enemy distance from Fireseed Planet: 7651 kilometers]

“Now, we must begin the battle,” he said in a low voice.

Despite the warning signals from the Fire Star, the Star Eater remained unmoved and continued its advance.

His every step seemed extremely slow, yet he was able to cover several kilometers.

The entire Tomorrow Alliance has entered battle mode.

The Peacemaker launched the first attack.

The electromagnetic railgun on the city deck was activated and opened fire.

Originally aimed at the Star Eater's left eye, the bullet deviated and ended up hitting an armor plate on the mechanical crown.

In an instant, a point of light burst forth at the point of impact.

The armor plate that was hit was immediately melted, and the twisted pipes and mechanical structures inside were briefly exposed to the vacuum, flashing with uncontrolled arcs of energy.

Large amounts of debris and metal dust erupted, forming a slowly spreading debris cloud.

The results seem remarkable, but that's all.

For the massive structure of the mechanical crown, this damage was like a crater being blasted into the deck of an aircraft carrier, not to mention the crown itself.

A strange look flashed in Yang Zheng's eyes, and his lips moved as if he wanted to say something but stopped himself.

The bombardment of electromagnetic railguns is undeniably fierce, and can even be described as virtually invincible.

But he never expected to encounter an enemy so large that it could ignore his bombardment.

The Star Eater ignored this minor incident and continued forward with an expressionless face.

Not far from him, three points of light suddenly appeared.

Those were none other than the Ember Angels, Source Angels, and Hunter Angels that Li Ye had deployed in advance.

After aiming at the Star Eater's eyes, pilot Tang Fang pulled the control stick to its maximum.

The Source Angel then advanced at full speed, with all its weapons activated and firing at full power.

Super-heavy twin-mounted railgun, plasma bombardment array, 240-cell miniature missile pod, intercontinental ballistic missile launcher, close-in weapon system rapid-fire cannon, neutron diffusion cannon, and hybrid ammunition drop pod.
However, the results were minimal.

The moment the railgun shell hit the eyes, it seemed to crash into an invisible, extremely dense spacetime wall, turning into puffs of spreading metallic vapor without even leaving a burn mark.

The plasma clusters scattered and splashed like water balloons hitting rocks, dazzling yet powerless.

The miniature missiles collided and exploded, forming a blazing inferno, yet they couldn't even deepen the ancient markings on the eyelids.

The rapid-fire machine gun opened fire fiercely, but could only produce a continuous burst of futile sparks.

As the light and dust from the explosion slowly dissipated, the face of the Star Eater reappeared.

Still cold, still indifferent.

"Estimated effective damage: 0.1%".

Inside the cockpit, Tang Fang's pupils widened slowly as he looked at the data displayed on the screen.

"How is this possible?" he murmured absentmindedly.

The Source Angels possess enough firepower to blast away an entire area, and when they attack the Star Eaters, it's like a silent splash in the ocean.

Not only the crowd, but even Li Ye was stunned.

But he quickly regained his composure.

"Changfeng, activate the energy phase blade device," he said in a low voice.

"Received, energy phase blade device activated." Changfeng's voice came through the communication channel. "Do you want me to bombard the Star Eater's head, Commander?"

After a moment's hesitation, Li Ye gave his answer.

"No, it doesn't have to be the head. Try bombarding the reverse-rotating star rings at his feet to destroy his mobility."

As the two super solar power reactors behind the Ember Angel began to operate, a supernova-like blue-white radiance burst forth, and the antimatter confinement ring of the energy phase blade device vibrated at an almost insane frequency.

A super energy beam was generated and manipulated by the Ember Angel to slash horizontally towards the Star Eater's feet!

However, the two counter-rotating star rings equipped by the Star Eater itself possess a huge and stable spacetime distortion field.

The super energy beam was quickly smoothed and neutralized, and even turned around to grab the Ember Angel holding the "sword hilt," attempting to pull it towards him.

Even when the Ember Angel maximized the output power of the dual super solar power furnace, it was still to no avail.

As the energy output ended, the super energy beam disappeared, and the Ember Angel lost its power to contend with the Star Ring. Like a stone launched by a slingshot, it was flung away into the distant deep space.
