"The changes are indeed not significant." Xi Xi looked him over from all sides before saying this casually.

After all, it was just a level up from level 3 to level 3.25, so she didn't have high expectations.

But at this moment, Aura, who had been jumping around excitedly in the car, accidentally pressed some button.

In an instant, a slight mechanical whirring sound was heard, and the roof, which was originally located above the rear of the vehicle, began to slowly move downwards, eventually forming a bunk bed with the bed below.

It's a liftable bunk bed!

Xi Xi walked over with delight, approached the bunk bed, and began to study its structure and function with great interest.

She even discovered that a small open space had sprung up between the kitchen area and the rear bed.

Xi Xi gestured in the air to measure the space, nodded with satisfaction, and placed the portable washroom out.

Chu Zhiqin, standing to the side, was naturally not as calm as Xi Xi. She was completely amazed by the RV, covering her mouth and staring at everything in disbelief. A feeling of joy welled up in her heart like a tide.

Xi Xi glanced at her mother, who was looking around, and returned to the driver's seat with amusement. Just as she was about to start the RV, she suddenly realized that the interior seemed to be a fusion of the styles of the two original vehicles, both familiar and strange.

Just like Xi Xi's lucky cat air vent ornament and her mother's phone holder in the car, the two are placed in similar positions, so when they are stacked together, they look like the lucky cat has a phone holder on its head, which inexplicably creates a unique sense of art.

Before Xi Xi could even sigh, she glimpsed in the rearview mirror that her mother had already happily picked up the little white duck, while Aura beside her was grumbling and tugging at her mother's trouser leg, looking quite like she was catching her mother in the act.

She suppressed her smile, quickly started the RV, and instructed Xi's mother to draw all the curtains before driving towards the east gate of the supply station.

As evening approached, the sandstorm in the desert almost subsided, and the number of people at the supply station began to increase.

Fortunately, the B-type RV and the large SUV are not much different in appearance. Xi Xi took advantage of the fact that it had not yet attracted too much attention and quickly drove towards the main east gate.

The doorway was longer than Xi Xi had imagined, like an endless black tunnel that made time seem to drag on.

After a long while, Xi Xi finally drove the vehicle out of the dark doorway.

At that very moment, the setting sun, like a golden scroll, suddenly unfolded before her eyes, its dazzling brilliance instantly filling her entire field of vision.

She glanced back through the rearview mirror, but what she saw shocked her – instead of a city wall, there was a towering, majestic mountain!

The mountain stands there like a giant, giving people a strong sense of oppression.

Xi Xi was startled. Without thinking, she activated the autopilot mode and quickly ran to the back of the car to investigate.

At the same time, Xi's mother also noticed something was wrong and looked at Xi Xi: "How come there's a mountain here? I don't remember it at all... Did you see it at the transfer station?"

Xi Xi stared at the mountain peak that was gradually receding into the distance and shook her head.

Judging from the current situation, they clearly came out of the cave.

However, the mountain was so tall, majestic, and magnificent that she couldn't possibly have missed it if it really existed near the transit station.

Just as Xi Xi was frowning and deep in thought, the car suddenly plunged into darkness once again.

"Another cave tunnel?" Chu Zhiqin looked at the receding light outside the window and asked with some confusion, "Wasn't it a desert before? How did it suddenly turn into a mountain road?"

Xi Xi understood; she finally realized why She Ji had said that the main east gate was for exiting only and not for entering.

The game map changes after you exit through the main east gate...

She quickly opened the light screen map and, sure enough, the vast yellow sand around her had been replaced by undulating mountain ranges.

“We’re already in the mountains now, and we’ll probably have to survive in the mountains this time…” Xi Xi said in a low voice. It turned out that the transit station really did serve as a “transit” as its name suggested.

Just then, the small RV drove out of the tunnel, and the two regained their sight.

The mother and daughter immediately looked outside and were greeted by a lush green landscape, with various trees arranged in a pleasing manner and mountains undulating in a winding manner, showing a vibrant state of life.

"That's wonderful, that's wonderful, Amitabha..." Xi's mother couldn't help but exclaim, putting her hands together and her face beaming with joy, "Finally, it's not that scorching desert anymore!"

The small RV drove into the mountain tunnel again, and the interior instantly darkened. Xi Xi felt a sense of déjà vu, as if she were in a high-speed train in the mountains of the original world, where there were tunnels one after another and cell phone signals were intermittent.

She silently opened the light screen, and thankfully it was still working normally. The public chat was still scrolling rapidly, with people still arguing about the sandstorm.

Fearing another sandstorm, people were reluctant to leave the comfortable supply station, and the parking lot was packed with vehicles.

Xi Xi gave a wry smile. How could these players have imagined that outside the East Gate, there was a peaceful and vibrant place, completely different from the harsh climate of the desert, like two worlds with no connection whatsoever.

She suddenly realized that the sandstorm might be the key factor driving the game's progress.

After all, even if players don't want to leave the supply station, their supplies and survival points will eventually run out, and then they will have to search for treasure chests to survive.

However, due to the sandstorm raging to the west, travel was impossible, so they would eventually have to take the road to the east.

Therefore, Xi Xi guessed that this sandstorm would not be the last, and that each subsequent one would be more intense than the last.

Just as she was making her own deductions, Xi's mother suddenly spoke up uneasily, "Xiao Xi, isn't this mountain way too big...? Why haven't we made it out of the cave yet?"

Xi Xi then looked up at the window and saw that the tunnel outside was pitch black. Apart from the low rumble of the RV moving forward, the silence was unsettling.

Her heart sank, and a strange sense of tension welled up inside her.

Xi Xi quickly went to the driver's seat and looked ahead. All she could see was endless darkness, not even a faint tunnel street light.

The small area illuminated only by the headlights was not enough for her to see how far the road ahead was.

Time passed by little by little, and with each passing minute, Xi Xi's anxiety increased.

The small RV seemed to be forever trapped in this long tunnel, as if imprisoned in endless darkness.

Xi Xi had a bad feeling, and a terrible thought suddenly flashed through her mind.

She was horrified and immediately reopened the light screen map, gasping in shock.

The mountainous areas on the light screen map have completely disappeared, replaced by a dark pixel map with winding, crisscrossing tunnels resembling a giant spider web, haphazardly covering the entire map interface.

It turns out, this time it wasn't about surviving on mountain roads! It was about surviving in a tunnel!
