Mobile City Travel Guide

"One, two, three, four..."

On the deck, Li Xin silently began to count.

Including myself, a total of 9 mobile cities have successfully broken through.

Actually, they were quite lucky. Just now, so many Federation warships had surrounded them from all sides, their firepower so dense that even the sky was dyed orange-red. If they had used those mobile provinces as "hostages" in time, coupled with the gravitational imbalance, they would probably have been completely wiped out.

The thought of gravitational imbalance made Li Xin subconsciously look up at the sea of ​​clouds above.

The thick, inverted ocean-like clouds, which covered the entire sky, were still slowly churning high above.

"Gravity imbalance... Why did it only start when the disturbance came from the depths of the sea of ​​clouds?" he murmured to himself.

This sudden disaster caused irreparable destruction to the entire aerial world. Along the way, all that could be seen were overturned floating islands and towns, moving provinces, and various unbalanced vehicles belonging to the aerial travelers.

The mobile cities are still moving slowly. After this battle, they are all battered and bruised, and the distance between them is no longer as tight; they are all loose and scattered.

To facilitate rest and maintenance, Gao Nan specially cleared space on the Tianyou K4 and urged all the mobile cities to hurry up and land on the deck.

Li Xin didn't rush off; his gaze fell on the bottom.

Only then did he realize with astonishment that, due to the gravitational imbalance, the black mist that had been spreading below had receded at some point! Moreover, compared to the previous depth of more than 10,000 meters, this time it seemed to be even deeper and farther away, with no end in sight.

Unbeknownst to him, his breathing gradually slowed down, and his eyes flickered.

"...Starfire? What are you doing?"

Seeing that the Spark did not come to dock and rest like the other mobile cities, but instead turned around directly, Gao Nan immediately asked in confusion.

Li Xin took a deep breath and gave his answer.

"We need to go down there and take a look."

Gao Nan remained silent in the channel for a while, then spoke softly.

"Good luck."

"Um."

As he nodded, Li Xin also felt a sense of melancholy and helplessness.

I finally found a team, but I didn't expect them to leave so soon.

This time, when we left and came back up from below, everyone was already far away.

I don't know when we'll meet again.

Just then, Gao Nan's slightly amused voice came through the channel.

See you in the next world.

Li Xinyan was taken aback.

"What?" he asked instinctively.

"This is what we often say when we say goodbye," Gao Nan said. "No matter how far the road is, or how dangerous it is, we will always meet again."

Li Xin nodded slightly, her brows relaxing gently.

"Okay, see you in the next world," he said.

With a roar, the Starfire adjusted its city-head to face downwards and slowly sailed downhill. The other mobile cities paused briefly, watching it disappear into the distance, as if paying their respects.

Then they continued on their way.

......

As we descended, time seemed to pass more quickly.

Perhaps because it was too quiet all around, or perhaps because there were very few things to see, the Starfire sank into deeper waters in the blink of an eye before it was even ready to experience a new sensation.

He gripped the railing tightly, his knuckles turning white without him noticing, as the scenery before him rushed by.

Having gained experience from previous underwater explorations, the descent was much smoother this time, and the Spark even increased its speed. The mobile city drew a steady and swift arc of descent in the air, and the readings on the instrument panel jumped at a speed visible to the naked eye.

"My lord, the overload mode of the power engine is ready," the helmsman reminded him.

"Hmm," Li Xin said in a deep voice.

With this trump card in hand, he felt even more confident.

A dozen minutes later, Xinghuo broke through the 10000-meter depth barrier.

But it was still very deep down, and you couldn't see the end of it.

"Just how many meters did the black fog descend this time?" Lu Chen exclaimed in surprise.

"At least 3 meters, I suppose," Li Xin mused.

Rather than staying in the safe cabin, the two chose to remain on the deck. They gripped the railing tightly, the deep roar of the engine and the whistling air currents filling their ears, along with the fearful yet expectant feeling as they looked down.

However, for safety reasons, they made sure to tie themselves up.

At a depth of 20000 meters, we witnessed an incredible spectacle.

A vast ocean of garbage.

Mountains, floating islands, town ruins, vehicle wreckage, household garbage, waste... It is made up of countless pieces of garbage, like a boundless wasteland suspended in an abyss.

The reason it exists is quite simple. Over the centuries, the aerial civilizations have dumped countless amounts of garbage below, and it has all accumulated here.

As the gravitational imbalance caused the black fog to recede once more, this garbage, which had accumulated for countless years, finally saw the light of day again.

"This..." Lu Chen couldn't help but feel troubled.

Judging from its scale, the ocean of garbage is incredibly deep, and even if the Spark rocket were to go at full speed, it wouldn't be able to break through it.

Li Xin, however, had an idea.

At his command, the Tiger-Squat cannons on the Starfire opened fire in quick succession. The first shell exploded on the surface of the sea of ​​garbage, like an invisible giant hand slamming a dent into the mountain of waste. The second followed closely, widening the dent. Then came the third, the fourth...

With this air cannon, the Starfire blasted a hole in the ocean of garbage.

Before the garbage from all directions could close in, the mobile city accelerated and plunged into the void.

With the alternating firing of multiple tiger-squat cannons, it successfully traversed the ocean of garbage.

Li Xin roughly estimated that the ocean of garbage was only two or three hundred meters thick, which is not very deep.

"Keep moving forward," he said.

The Xinghuo continued its descent at a steady and deliberate pace.

Upon reaching a depth of 30000 meters, a breathtaking scene unfolded before our eyes.

Thousands of floating islands, countless towns and cities, unimaginable metal megastructures, and a wide variety of aerial vehicles... the remnants of a previous aerial civilization are vividly presented.

Everything in this fault-bound civilization is at the level of modern technology.

"This aerial civilization was far more advanced than the current one, yet it still went extinct," Li Xin thought to himself.

Upon closer examination, countless ancient civilizations may still be hidden beneath the black mist. They simply vanished silently into the mist after their demise, never to be seen again.

"My lord, this depth is already terrifying," the helmsman's voice came through the loudspeaker. "If we descend any further, I'm afraid..."

"Don't worry, I know what I'm doing," Li Xin replied in a deep voice. "Let's continue."

He looked down, his eyes gleaming.

Just started.
