The pure white glow receded like a tide, and the illusion of weightlessness and sensory deprivation was quickly replaced by an unprecedented sense of fullness.

Perception was the first to return.

As if suddenly diving from thin air into the deep sea, elemental energy of all kinds, so dense it almost turned into substance, instantly enveloped everyone in the train car like warm, heavy seawater.

This concentration far exceeded any terrain Outside the Realm; according to everyone's perception, the elemental concentration here was nearly ten times higher or even more than that ⊛ Nоvеlιght ⊛ (Read the full story) of the outside.

With every breath, what was inhaled was no longer simple air.

Instead, it was a surging and active flow of energy, making even Bai Cheng, who had just broken through, feel her meridians swell slightly, while Yu Nian couldn't help but let out a low cry.

"Is this... the Infinite Realm?" Yu Nian looked around the interior of the train car, seemingly trying to find some difference, but aside from the ubiquitous, dense elements, the train itself remained unchanged.

Just then, Leng Ningxue's cold voice rang out, carrying a hint of subtle surprise: "Look outside."

Hearing this, Bai Cheng and Yu Nian immediately cast their gazes out the train window.

The sight that met their eyes left them both momentarily stunned.

The train seemed to be floating or traveling over a vast, boundless expanse of water.

As far as the eye could see, there was a vast, deep blue ocean, its surface calm and waveless, reflecting a soft and constant shimmer from the sky.

Islands of various sizes were scattered across the sea like stars, most of them covered in lush vegetation and teeming with life.

Even more peculiar was that the water between the islands was not empty; instead, large patches of various green plants grew there.

Some spread out like lotus leaves, others swayed like water grass, and some bore tiny, twinkling fluorescent flowers.

From a distance, the entire sea did not look like a violent ocean but rather an infinitely magnified, island-dotted tranquil pond or Swamp wetland, exuding a strange and harmonious beauty.

"This place..." Yu Nian blinked, her face full of confusion, "It doesn't seem... fundamentally different from Outside the Realm, does it? Except for these aquatic plants being a bit special."

Bai Cheng also frowned slightly, her perception extending in all directions like an invisible spider web.

A moment later, she retracted her perception, the confusion in her eyes deepening: "The elemental concentration is indeed staggering, but... most of the surrounding life force is peaceful and weak, mostly ordinary animals and plants relying on these dense elements to survive."

"I haven't sensed any powerful or threatening fluctuations of aura, let alone the world full of powerhouses I imagined."

This was completely different from the world of powerhouses, full of danger and opportunity, that they had imagined based on the name "Infinite Realm" and their previous encounters.

It was quiet, fertile, and even... unrealistically peaceful.

"Could it be that the so-called Infinite Realm isn't a battlefield, but a holy land for cultivation?" Leng Ningxue mused, her fingertips unconsciously tracing the cold glass of the train window.

Just as the three were discussing their doubts about this seemingly calm otherworldly scene, the System screen in the car, which had been silent for a long time, suddenly flickered without warning.

The light on the screen flickered unsteadily, as if it might go out completely at any moment, or like a struggle before a signal was permanently cut off.

Then, several intermittent lines of notification messages, with fonts sometimes clear and sometimes distorted, struggled to emerge:

【Welcome... to the Infinite Realm!】

【Your final mission... has been completed. The System will enter a slumber...】

【In the upcoming journey, the train will no longer be subject to any restrictions. You... can go anywhere you want!】

【Hint: Some functions will also become invalid due to the System's slumber. If you wish to develop technology... please customize your train yourself...】

The information was messy and incomplete, with key parts filled with interference ripples and gaps.

The last hint didn't even fully display before blurring completely, and the light on the screen dimmed until it was almost extinguished.

Only an extremely faint flicker remained, like a candle in the wind, indicating that the connection with the "System" might have weakened to the limit.

When the screen went out completely, it signified that the System had entirely disconnected from them.

Bai Cheng, Leng Ningxue, and Yu Nian quickly exchanged glances, their faces showing unconcealable surprise.

This wasn't the clear, mandatory, and unquestionable System command of the past, but rather fragmented information full of glitches, interference, and uncertainty.

"The System is actually going to disappear?" Bai Cheng whispered, repeating the most alarming phrase on the screen, her gaze turning back to the quiet and eerie waters outside.

At this moment, this seemingly peaceful world, in their eyes, was suddenly shrouded in an unfathomable mist.

"Logically speaking, if we were the System's pawns..." Leng Ningxue frowned, "it should have held onto us even tighter after sending us to the Infinite Realm."

Bai Cheng also nodded; this was indeed quite inconceivable.

Yet now, when the number of Survivors who could reach the Infinite Realm wasn't even a handful, the System had let them roam free.

Strange, this was truly too strange.

"The train can also move automatically now. Does it mean we are completely free?" Yu Nian said uncertainly.

They could be certain of at least two points regarding the changes that occurred after entering the Infinite Realm.

First, the System had disappeared, and some functions were restricted; second, there were no longer any Platform restrictions.

They could go wherever they wanted.

But it was precisely this excessive freedom that the three found most suspicious.

The signs of the System "losing contact" perhaps proved more than any powerful enemy that they had truly stepped into a completely new domain with vastly different rules, where even its control might be weakened or distorted.

After a moment of silence in the car, Bai Cheng was the first to break the quiet, comforting them: "Since we're here, let's take things as they come. There's nothing to worry about."

"That's true," Ningxue smiled.

Yu Nian was still a bit lost: "But where is our next destination? Are we just going to wander aimlessly like this?"

Hearing this, Bai Cheng curled her lips into a smile: "Isn't that easy to decide?"

With that, she went to the window and pointed toward a small island in the distance.

"Since the rules here have changed from linear levels to an open world, let's just explore freely!"

"For our first target, let's go check out that island!"

Right now, they knew too little about the Infinite Realm, so adventuring deep into it was clearly unwise.

Since they were sent here by the System, it meant this place must be on the edge of the Infinite Realm.

At least with their current strength, Bai Cheng was confident that they wouldn't encounter any danger for the time being.

Yu Nian could only nod and say, "Alright then."

"Xiaoyu, start the train!"

"Yes, Miss!" Lan Xiaoyu decisively operated the train.

The massive steel beast immediately turned around and sped toward the island not far to the right.
