270: Chapter 270 Lv.6 Floating Cruiser Land Boundary! The Polaris Ascends to Heaven

9:00 AM on the 76th day.

The countdown begins.

1440.

1439.

1438.

Polaris hovered at an altitude of one thousand meters.

The faint blue energy shield surrounding it turned incandescent white the moment the upgrade initiated.

A blinding white light radiated from every inch of the city's surface.

At that moment, all living creatures and Mobile Cities on the ice sheet saw a new light source appear in the sky.

"Cheng Zheng." Lu Chen pressed the communication button.

"Here." Cheng Zheng's voice was tense.

"Tell Forge and Evening Bell. Polaris is upgrading to Lv.6."

There was silence on the other end for a full ten seconds.

"City Lord Lu." Cheng Zheng's voice was very soft.

"There is no precedent for Lv.6 on Blue Star. The highest known level is Lv.5. Dawn is Lv.5. The crusher is Lv.5. No one has ever reached anything higher."

"Now there is."

1200.

The city was changing.

Its length of 3,200 meters began to extend to a larger scale.

4,000 meters.

5,000 meters.

6,000 meters.

The width expanded from 1,100 meters to 2,000 meters.

The height stretched from 420 meters to 800 meters.

The city's form was also changing.

It broke away from the traditional rectangular shape of a Mobile City.

The anti-gravity array at the bottom reorganized into multiple independent suspension modules. Giant metal limbs extended from the bottom of the city.

Six of them.

Each limb was over 1,000 meters long, with independent propulsion units and weapon hardpoints at the tips.

Viewed from below, Polaris resembled a giant steel spider hovering in the sky.

It transcended the form of a spider.

This was a floating fortress.

A city in the sky with six giant legs.

900.

The upper structure of the city continued to expand.

20 stories.

30 stories.

40 stories.

The top of the main building reached its final height. A giant dome structure formed on the top level.

Inside the dome was the expanded Miniature Planetary Ecological Engine.

It covered an area of over 100 square kilometers.

A 100-square-kilometer indoor ecosystem.

There were mountains.

There was water.

There was the prototype of a forest.

There was wind blowing.

600.

The weapon systems on the six limbs were growing.

Each limb was equipped with independent particle beam turrets and gravity collapse missile silos.

Coupled with the antimatter annihilation ray main cannon above the main body and the orbital mech airdrop array.

The firepower covered everything from the ground to outside the atmosphere.

400.

The Cockpit had risen to the very top of the 40th floor.

Looking out from the observation window.

The clouds were beneath one's feet.

The ice sheet was even further below.

It was a white land, illuminated by the faint aurora of the polar night.

200.

"City Lord." Lin Wan stood in front of the observation window.

Her voice was extremely soft.

"Hmm."

"We are in the sky."

"Hmm."

The white light receded.

The energy shield changed from incandescent white back to faint blue. It then expanded beyond the tips of the six legs.

A line of text popped up on the panel.

The color was beyond the category of red.

It was not gold either.

It was a pure, unblemished white.

White text.

[City upgrade evolution complete. Polaris. Lv.6 Floating Multi-legged Cruiser Land-Boundary.]

[Super-specification bonus: Area expanded by 240% compared to standard Lv.6. 45-story structure. Six-legged floating configuration. Strong Artificial Intelligence global warfare management. Miniature Planetary Ecological Engine fully loaded. Planetary-class Core Engine online at full power.]

[Highest level Mobile City currently known on Blue Star.]

[No precedent.]

This was no longer the Cockpit.

This was a holographic projection command hall over 200 meters wide.

A giant circular holographic screen hovered in the air, displaying all terrain and signal information within a 500-kilometer radius centered on Polaris.

Lu Chen stood in the center of the command hall.

Beneath his feet was a transparent floor.

Clouds surged below. The ice sheet spread out into the distance to the edge of the horizon.

"Polaris." He called out.

"Present." The voice of the Strong Artificial Intelligence came from all directions.

"Report current status."

"Polaris. Lv.6 Floating Multi-legged Cruiser Land-Boundary." Polaris reported.

"Total length 7,600 meters. Total width 3,200 meters. Total height 1,200 meters."

It paused for half a second.

"Six-legged floating configuration. Current hovering altitude 3,000 meters. Internal ecosystem area 127 square kilometers. Population capacity limit 500,000."

"Weapon systems."

"Main weapon. One antimatter annihilation ray main cannon. Effective range 800 kilometers."

Polaris's electronic voice echoed in the spacious command hall.

"Secondary weapons. Twelve high-energy particle beam turrets, distributed at the tips of the six legs. Effective range 150 kilometers. Twenty-four gravity collapse missile silos. Effective range 1,000 kilometers."

Dense red dots lit up on the holographic screen.

"12,000 orbital airdrop mechs. 60 tactical fusion nuclear missile reserves. Railway Gun array upgraded to electromagnetic railgun matrix. 32 turrets. Effective range 95 kilometers."

It continued to add.

"Phalanx CIWS upgraded to a global particle interception net. Coverage radius 50 kilometers. Theoretically capable of intercepting any incoming object below sub-light speed."

Zhao Tiezhu stood at the new war command console.

His two hands rested on a control interface ten times larger than before.

The dense weapon icons on the interface were all glowing green.

He couldn't say a word.

He just rubbed his palms, then rubbed the corners of his eyes.

"Defensive systems." Lu Chen continued.

"Light-prism fusion energy shield has been upgraded to a global fusion shield. Covering the entire city."

Polaris pulled up the armor structure diagram.

"Space distortion refraction layer thickness increased to 3 meters. Theoretically capable of deflecting all solid projectiles below 10% of the speed of light."

A blue protective layer lit up on the screen.

"Neutron star density armor film has covered the entire outer wall. Equivalent protective thickness exceeds 10,000 millimeters of homogeneous steel. Carbon-based polymer composite armor covers everything as an inner lining layer."

It made a final summary.

"Memory alloy self-repair layer online. Any non-fatal damage will be automatically repaired within ten minutes."

"Power systems."

"Planetary-class Core Engine running at full power. Cold Fusion Stellar Reactor online as auxiliary power. Zero-point energy intake module continuously replenishing."

Polaris switched to the power interface.

"Space curvature engine prototype upgraded to a complete space curvature propulsion system. Theoretical top speed is not limited by the speed of light. It depends on the stability of the space curvature bubble."

It reported the final data.

"Current safe cruising speed. 2,000 kilometers per hour."

2,000 kilometers per hour.

The diameter of the ice sheet was less than 20,000 kilometers.

It could circle the ice sheet in ten hours.

"Ecosystem."

"Miniature Planetary Ecological Engine fully loaded. Internal climate self-circulating. Artificial sun system simulates standard day-night cycles."

Polaris displayed images of the lush green ecosystem.

"Theoretically, there is no upper limit to the daily food production of the material conversion synthesizer. It depends on energy input."

The screen switched to a close-up of a seedling breaking through the soil.

"The gene bank has activated the first batch of species restoration programs. Temperate broad-leaved forest seedlings have taken root in the ecosystem. The local space weather controller can manipulate the weather within a 500-kilometer radius outside the city."

Weather within a 500-kilometer radius.

"Polaris." Lu Chen spoke.

"Present."

"If I command you to create a continuous warm air current below Polaris's hovering position, can you make this ice sheet start to melt?"

The command hall was silent for two seconds.

"Yes." Polaris replied.

"The weather controller can create a continuous warm and humid air current within a radius of 100 kilometers below the city."

It marked a red area on the holographic map.

"Combined with the fine-tuning of the gravitational field from the Planetary-class Core Engine, the surface temperature of the target area can be raised above zero degrees."

"The ice will melt."

"The snow will melt into water. The permafrost will thaw. The soil will be exposed."

Polaris projected the timeline.

"If plant seeds from the gene bank are dropped simultaneously, theoretically, initial vegetation cover can be established in the target area within three to six months."

The ice sheet.

It will become a green land.

Lin Wan's hand clutching the notebook was trembling.

She was not afraid, nor was she excited.

From the very first day.

From that one Cabbage.

She had been doing one thing.

Planting things.

Planting things in the ice and snow.

Making things come alive.

Now she stood in a city floating in the sky.

This city could make the ice sheet itself come alive.

"City Lord." She spoke. Her voice was steady.

"Speak."

"I want to go down and plant trees."
