Mobile City Travel Guide

During the descent, Li Xin saw several relics of previous aerial civilizations.

Some were only at the primitive level, their creations being nothing more than simple wooden floating platforms, animal skin huts, stone axes, and empty boats made of vines, like newborns that had just cried out but died soon after.

Some are of ancient scale, with stone-built towns, carved wooden beams and pillars, city walls and towers, sailboats and catapults, already showing the beginnings of a kingdom.

Others bear clear traces of the modern era—the skeletons of steel mills, chimneys and iron bridges, steam engines and rifled cannons—revealing the ambition for a flourishing civilization.

These fragmented civilizations are layered one on top of another, like a history book bound together but forgotten.

Upon reaching a depth of 40000 meters, an unprecedented and breathtaking sight appeared.

This is a completely new ecological environment that has been "sublimated" from the black fog.

As far as the eye can see, there are lush floating islands and mountains, covered with thick vegetation, like pieces of jade that have been imbued with life for millions of years. Thousands upon thousands of aerial creatures roam among them, each with a unique and bizarre appearance.

Even the plants are diverse in shape, floating and drifting freely.

Everyone rubbed their eyes, their expressions filled with disbelief. After passing through countless layers of desolate ruins of civilization, a vibrant world had appeared before them.

"Be careful, everyone, and prepare for battle," Li Xin reminded them.

The aerial creatures that had been sublimated through the black mist were incredibly powerful and difficult to deal with. But unexpectedly, the Starfire's descent went very smoothly, with no aerial creatures bothering it at all.

During this time, Li Xin unexpectedly discovered a mobile city of humans.

It was a large, mobile city, entirely silver-white and exuding a high-tech feel. At this moment, it was stationed on a floating island and had deployed a group of researchers in uniforms.

"Which human organization is this?" he wondered.

Finally, upon reaching a depth of 50000 meters, Li Xin was able to see the black fog.

It is about two or three thousand meters away from the bottom.

Moreover, another remnant of a previous aerial civilization was discovered in Lixin.

Compared to what we've seen before, this floating civilization's technological level is beyond imagination. Whether it's the floating islands, towns, vehicles, or megastructures, their advanced nature is beyond description.

Strangely, this fragmented civilization was completely submerged in the black mist. The mist flowed slowly around them, like a living, conscious shroud, inextricably entangled with them.

Suddenly, a bold guess came to Li Xin's mind.

Did this advanced aerial civilization choose to develop "downward" and attempt to break through the black fog?

"Just what is this black mist? Even a spacefaring civilization of this level can't break through it?" he wondered.

Just as he was filled with doubt, a horrifying scene unfolded.

The black mist began to slowly churn somewhere—not in a random, aimless flow, but in a more concentrated and conscious convergence.

It gradually compressed into a huge, hemispherical bulge.

Immediately afterwards, a gigantic single eye, several kilometers in size, slowly opened.

Its pupils shone with dazzling starlight, each ray carrying a breathtaking, indescribable beauty and eeriness. Its eyes swirled between deep brown and dark gold, like a pot of slowly stirred, melting stars.

That eye was fixed straight on the Starfire above.

After a moment of stunned silence, Li Xin immediately waved his hand and gave the order.

"Return to base immediately!"

The Spark quickly adjusted its direction and roared upwards.

Li Xin gripped the railing tightly, staring at the one-eyed man below, his heart filled with horror.

The black mist is alive! The "Mother of Mist" that the Sky Traveler spoke of is actually real!

Just when he thought the giant eye would chase after the Starfire, it made no move.

It simply stayed quietly in place, too lazy to even move, its eyes revealing indifference, or even a hint of amusement.

......

[You have completed the "Descending Quest" and received 5000 Evolution Points as a reward!]

"Phew." Li Xin let out a long sigh of relief.

After a long ascent, the Spark safely returned from beneath the black fog, without even needing to use overload mode. By this time, a considerable amount of time had passed, and the Skyrocket K4 and other mobile cities had long since vanished without a trace, with even the city radio stations unable to receive signals.

Soon, he began to eagerly evolve the items.

The first thing to consider is training personnel who can drive vehicles.

Li Xin's idea is to build a simple training pod on the Starfire and then give it functions through evolution.

He acted immediately, quickly choosing a cabin and manufacturing a series of equipment in the production workshop, such as height-adjustable seats, helmets with built-in simple communication modules and displays, simple control consoles and instrument panels, and so on.

Once laid out, the panel immediately appeared in front of me.

【Item Name: City Simulation Training Pod】

[Description: A makeshift training pod converted from an unused cabin, equipped with basic assembly line equipment, offering limited functionality.]

[Evolutionary Branch:]

[Energy Consumption Optimization: Training pods consume 30% less city energy] - 300 Evolution Points

[Perception Immersion: When in the city simulation training pod, the time flow ratio with the real world is 1:24.] -500 Evolution Points

[Virtual World: You can enter a highly realistic training space by wearing a helmet, featuring various training scenarios, vehicles, weapons, and environmental parameters, supporting multiplayer collaboration.] - 1000 Evolution Points

Li Xin stroked his chin. This evolutionary branch was fairly standard. The third evolutionary branch, however, made his eyes light up. Wasn't this exactly what he wanted? It could not only be used to train personnel to drive vehicles, but also to cultivate other technical talents, and even for entertainment.

After payment, the training pod had become incredibly high-tech. The entire pod featured a simple yet sophisticated silver-white color scheme, with smooth, mirror-like walls outlined with unfamiliar geometric patterns. Even the simple equipment had been transformed: the control console had become a touch panel, the helmet had subtle, flowing data patterns inside and out, and the seats had become futuristic gaming pods.

Then he directly purchased the "Perceptual Immersion" evolutionary branch—undoubtedly an extremely useful feature. A time flow ratio of 1:24 means that 24 hours inside the training pod is equivalent to only one hour passing outside. This can accelerate the training process.

In just a few days, Lixin will be able to train enough people to fly helicopters.

However, to his surprise, the training pod also consumed a lot of energy, so he had to purchase the "Energy Optimization" evolution branch.

"These evolution points really don't last long; 1800 points are gone in no time."

With that thought in mind, he lay back in his seat and put on his helmet.
