When they left Yunhai City, the five leaders willingly presented Bai Cheng and the others with a total of twenty-five thousand demon crystals.

Although the demand for demon crystals was increasing as everyone's level gradually rose, even a mosquito's leg is still meat.

Although this mission was simple, it couldn't help but leave Bai Cheng feeling a bit disappointed.

"This is already the seventh Sequence Station, yet I didn't expect there to be nothing in Yunhai City."

"Exactly. Who would have thought this was just a racial gathering place for those stinky fellows?" Yu Nian also expressed deep dissatisfaction with this.

The Human-faced Griffins in Yunhai City were immortal, so they couldn't gain experience points by killing these magical beasts.

"Forget it. Let's pack up and prepare to head to the next Station." Bai Cheng withdrew her thoughts and didn't seem too concerned about the situation.

In any case, the twenty-five thousand demon crystals they harvested this time could be considered a substantial gain.

"Qingniao, you absorb these demon crystals," Bai Cheng said.

Upon hearing this, Qingniao immediately thanked her, his voice hoarse and his words respectful: "Thank you, Miss!"

The reason for having Qingniao absorb them was simple: after his quality advanced to Immortal, his level was almost the highest besides Purple Iris. Coupled with his pure combat characteristics and high mobility from being able to fly, he [N O V E L I G H T] was the most suitable candidate to cultivate into the second King-level employee.

And these twenty-five thousand demon crystals would definitely allow him to break through to the King level.

As for the remaining Purple Iris, she continued to pour resources into the next employee.

Everyone quickly passed through the tunnel and returned to the Entrance Station.

Inside the train, the screen was currently displaying the reward for this Station.

【Reward Acquired: Coating Technology】

【Introduction: This technology does not require manual selection; it will automatically be equipped to your train without consuming any cost. Its main functions include preserving oxygen and resisting extremely harsh weather.】

【Evaluation: A cold-proof suit exclusive to the train? A diving suit??】

At the moment Bai Cheng closed the train notification, a transparent film, like a bubble, began to spread outward from the screen, quickly covering the entire train.

Now that the coating was complete, the train looked exceptionally new, shining brightly under the lights.

Even the train doors had a layer of film, and the top platform formed a hemisphere, which did not affect the growth of any planted crops.

Yu Nian, who was standing near the door, immediately reached out her hand curiously upon seeing this, only to find that the film covering the door did not break.

Then she entered the train completely, and still nothing changed.

At least it looked like this thing wouldn't break easily.

Looking at the system prompts combined with the Station information, Bai Cheng already had a faint guess about the terrain of the next area.

"An oxygen-deprived environment? Are we going to outer space?" Yu Nian couldn't understand. She couldn't think of anywhere else without oxygen, except outer space or underground.

Leng Ningxue patiently explained: "It also provides cold resistance, and since it's an oxygen-deprived environment, it's clearly located in a high-altitude area."

"What's the point of guessing? We'll know once we go and see."

Bai Cheng, on the contrary, was somewhat excited about this.

"This is the last terrain before entering the Infinite Realm. I want to see what else the System can pull off."

After speaking, she immediately instructed Lan Xiaoyu to depart.

As the train started, the Triangular Curtain turned to ashes, followed by a blinding white light.

Naturally, the others were as curious as Bai Cheng. After adjusting to the intense light, they immediately looked out the window.

As far as the eye could see, clouds and mist drifted vaguely; the surroundings were completely white!

Unlike the constantly undulating golden sea of sand, the dense clouds and mist surrounding them surged continuously this time. Relying only on sight, it was impossible to tell what lay beneath the clouds.

The rails automatically generated in the sky, and the train gradually accelerated. The entire firmament seemed to be ripped open by a fissure, and thick clouds rolled around the train like liquid silver.

"Is this the Heavenly Palace? It's beautiful!"

Yu Nian was extremely delighted by the surrounding environment. She stood by the window, stood on her tiptoes, and strained to look down, realizing the rails were completely suspended in the air. 𝒇𝒓𝒆𝒆𝙬𝒆𝒃𝓷𝒐𝓿𝙚𝙡.𝒄𝓸𝒎

Now was certainly not the time to discuss Universal Gravitation. She immediately turned back and said to Bai Cheng: "We seem to be in the sky, above the clouds!"

After Bai Cheng withdrew her gaze from the window, her attention was already fixed on the Detection Platform beside her.

【Current Area: Sea of Clouds and Sky】

【Current Status: None】

【Distance to Next Station】

"Sea of Clouds and Sky?" Bai Cheng murmured. "It seems we really are in the sky."

She looked at Lan Xiaoyu, who immediately understood and began pushing the train's Brake Lever.

With the friction of metal and the scattering of sparks, the train quickly came to a stop.

Opening the train door, Bai Cheng tried to extend her hand past the coating. As a result, she immediately felt an extreme chill, which also caused her stamina and energy to rapidly deplete.

The effect of this cold air was almost identical to the Cold Erosion of the Frigid Snow Mountain, but dozens of times stronger.

"The System probably doesn't want us to get off the train here," Bai Cheng frowned.

Afterward, she took out 【Destiny】 and pulled the trigger downward. The bullet shot through the sea of clouds, leaving a straight white streak before instantly disappearing.

This was indeed ten thousand meters high, and the outside world was accompanied by extremely harsh debuffs.

Of course, in this environment, there would be almost no resources outside.

In other words, the only thing everyone could do in this final terrain was purely travel.

"This is too boring. And this time, it's a journey of ten thousand kilometers..." Bai Cheng was speechless.

"Ten thousand what? Look again," Leng Ningxue corrected her with an eye roll.

Bai Cheng was confused and looked back at the Detection Platform.

"How much? One hundred thousand kilometers!"
