Mobile City Travel Guide

Li Xin's expression darkened slightly.

It turns out that the Sky Travel Civilization is a unified civilization with a federation as its core.

When they passed the ruins of that town, a few people chose to stay, while the main group continued onward.

500 meters, 1000 meters, 1500 meters... As the descent increased, all sorts of scenery appeared before our eyes.

A series of floating islands stacked one on top of another.

Various crashed aerial vehicles.

Giant vegetation reshaped by the black mist.

When the descent reached an altitude of over 3000 meters, everyone gasped in surprise.

Before them lay countless wrecked aerial warships, some broken in two, some shattered, and some completely capsized.

"This must be a warship from the Glorious War. That war lasted for decades and killed many people," Amy whispered. "But the textbooks say it was a war that had to be fought for peace."

This time, the vast majority of people stayed. The wreckage of the warship was an absolute treasure trove. Its copper pipes could be dismantled and used for piping, its rivets could be melted down and recast, and its steel plates could be cut and patched back onto the hull. Pressure gauges, valves, steering wheels, main guns... any parts from the warship that could be used after being dismantled could be sold for money.

In reality, steel is never readily available in the Skywalker world. Since there is no land, the Skywalkers can only extract it by mining veins in floating islands and mountains. Aside from the Federation's surplus steel production, most of the steel used in daily life is recycled, such as steel plates salvaged from abandoned steamships and iron ingots melted down from discarded pipes.

Therefore, the wreckage of these aerial warships is a very rich treasure.

The Iron Mole joined in, cutting directly at the wreckage of a warship and using its robotic arm to transport large chunks of scrap metal back to the city for smelting.

Li Xin is hesitant.

On the one hand, the scrap iron resources here really tempted him; on the other hand, he hadn't even descended a quarter of the way yet, and he wanted to continue exploring further.

After much deliberation, he decided to continue. Matthew originally wanted to stay put in the Windcatcher, but his sister grabbed his clothes and persuaded him to stop.

So, the Spark adjusted its course and continued its descent, not forgetting to sound its horn at the Iron Mole as a greeting.

Besides the Spark, there were also some scattered speedboats, flying machines, and steamships traveling together. Everyone's mentality was similar to that of gamblers, hoping that something even better might be waiting for them.

A dozen minutes later, Li Xin received the helmsman's report.

"My lord, the radar has detected a large number of bright spots several hundred meters away!"

"What?" Li Xin frowned.

The spots of light meant life. At first, he thought they were another group of deep-sea treasure hunters, but he was wrong. What appeared was a large swarm of aerial creatures.

They were several times larger than those we had seen before, their strength and speed had increased by an order of magnitude, and their shape and appearance were incredibly ferocious.

Upon seeing the faint black mist swirling around them, Li Xin instantly understood.

"This is a creature that has been swallowed and sublimated by the black mist!"

The Starfire immediately unleashed its full firepower, relentlessly bombarding and strafing these aerial creatures. Strangely, their shattered bodies began to churn and rapidly regenerate.

Only by completely destroying them can they be completely killed.

Seeing this, Li Xin was too lazy to argue any further. After gathering enough of the remaining mission supplies, he ordered the Starfire to continue its descent.

When the descent reached more than 8000 meters, the brother and sister finally began to worry.

At this moment, the black mist at the bottom could be faintly seen, and there were very few people left in the group.

Even Li Xin himself was a little apprehensive. Firstly, he had seen many novel sights along the way, but hadn't made any truly valuable discoveries. Secondly, he worried that if the tide came in again after diving so deep, he might not have time to retreat.

Just as he was about to order the return voyage, he caught a glimpse of something and was immediately stunned.

"What is that thing?"

About two thousand meters below, there was a gigantic island. And on that island lay the ruins of a modern city!

"......"

Li Xin rubbed his eyes in disbelief and then raised the binoculars again.

Skyscrapers, asphalt roads, overpasses... Yes, it was indeed the ruins of a modern city.

Without giving it much thought, he immediately ordered the Spark to descend at full speed.

Even Matthew and his sister got excited.

"A relic! This is the relic mentioned in the exploration manual!" Matthew exclaimed excitedly. "We're going to be rich this time!"

A few minutes later, the Spark hovered above the city. The people on deck erupted in excitement, all staring at it in disbelief. Meanwhile, the brother and sister piloted the Windcatcher into the city and began scavenging.

Amidst the murmuring crowd, Li Xin gripped the railing tightly, staring intently at the city ruins before him.

I never expected to see this scene beneath the black fog. Is this a former spacefaring civilization buried by a fault line? And what caused its destruction?

As he thought about it, a slight smile crept onto his lips.

This aerial travel around the world is far more interesting than I imagined.

Half an hour later, the brother and sister returned home happily with their bounty.

Li Xin glanced at the spoils they had brought back.

There were cell phones, computers, refrigerators, and mostly stacks of books and technical documents. However, due to being constantly submerged in black fog, they had all become defective.

He roughly understood the Federation's intention in conducting the "Black Fog Submarine Exploration" mission: to search for and acquire as many technological products and documents as possible from these previous civilizations in order to analyze and produce them.

However, for him, a modern person, it was just something he was used to.

The process of rising is far more difficult than the process of falling.

The Starfire needed to be half-raised and its engine running at full power, and the load on the engine gradually increased. The effort required to rise one meter was several times that required to descend one meter. People on the deck also needed to hold on tightly at all times.

While gripping the railing, Li Xin looked down into the black mist below.

It seemed to be very, very deep there, and it held even more secrets.

When it rose to more than 5000 meters, the bottom suddenly began to tremble violently.

"You need to speed things up, the Mother of Mist is about to come back up," Amy warned.

Li Xin nodded and ordered the helmsman to increase the engine speed.

In the following time, the tremors at the bottom became increasingly violent. At the bottom, which was beyond the reach and even the sight of the crowd, the previously still black mist began to surge and rise again.

Floating islands, mountains, giant vegetation, vehicles, and city ruins... everything that was revealed by the receding tide was submerged again by the black fog.

It was as if the Mother of Mist had generously displayed everything before taking it back.

When the Spark returned to an altitude of over 3000 meters, most of the troops in Rustwind Town had already withdrawn.

To everyone's surprise, the Iron Mole was still there.

It stopped not far away, next to a large pile of cut-up scrap metal, and sounded its horn to signal to the Starfire.

Li Xin immediately understood what was going on; this was something the other party had specifically left for him.

After sounding his horn to thank the Iron Mole, he immediately ordered the Starfire to quickly gather the pile of scrap metal and then follow it up.
