Hello, is this a letter addressed to Demon Fortress?

The wheelless train, controlled by Lin Gui, is demonstrating the true essence of levitation in the night.

The entire 20-meter-long steel train moved as smoothly as if it were gliding on ice.

Every turn was incredibly smooth.

The wheels maintain a constant 10-centimeter gap from the ground.

It was as if the entire train carriage was suspended on an invisible track.

This was a world of difference compared to the bumpy ride Betty had taken with her before.

When Betty was in control, the train lurched and staggered like a drunkard.

The carriages emitted a constant, ear-piercing screeching sound.

Now, even on the steepest turns, you can't feel the slightest bump.

It's like riding on a feather lifted by a gentle breeze.

"Mr. Lin, Mr. Lin the Ghost..."

Betty timidly approached the front of the car, clutching the spellbook tightly in her hand.

"Could I ask you a question? Why doesn't your car sway at all when you turn?"

Lin Gui answered calmly while maintaining precise control of the train.

"The key lies in prediction."

"You need to sense the subtle changes in the airflow ahead and start adjusting your magic output before you turn."

He extended his left hand, his fingertips shimmering with a pale blue magical light.

"Look, like this, you start fine-tuning the direction 30 meters in advance, instead of making a sharp turn when you're about to turn."

Betty opened her eyes wide, trying hard to remember every detail.

In the middle of the train not far away, Freya appeared to be focused on maintaining her invisibility magic, but in reality, she was secretly listening.

She tilted her staff slightly, allowing her to hear Lin Gui's explanation more clearly.

"Then, how do you maintain such a stable height?"

Betty pressed on, her voice tinged with urgency.

"Imagine you're holding a bowl of water, not a train," Lin Gui patiently explained.

"You need to keep the water level at all times; any sudden rise or fall will cause the water to spill out."

As he spoke, he demonstrated, and the train indeed did not experience even the slightest undulation.

Freya nodded unconsciously, a hint of understanding flashing in her icy blue eyes.

She pretended to tidy her long hair, which had been ruffled by the night wind.

In reality, he simply shifted his body slightly towards the front of the car.

Just as the lesson was in progress, Shia's voice came from the front.

"Attention, there are three ancient trees arranged in a triangle about 300 meters ahead."

"The tree canopy is exceptionally dense, and there are a lot of fallen leaves on the ground."

Scholar Eli immediately bent down to search on the map, his fingers swiftly tracing the parchment.

"The ancient triangular tree...we are approaching the slumbering woodland."

"It is recommended to increase the altitude to avoid the nocturnal bats in the canopy."

Lin Gui nodded slightly, and the train then rose smoothly, perfectly avoiding the dangerous area.

"That's amazing..."

Betty murmured to herself, sensing the traces of Lin Gui's magic, and her notes flew as she wrote.

Freya finally couldn't help but speak, her voice still maintaining the authority of a team leader.

But with a hint of barely concealed curiosity:

"Little mage, where did you learn all these skills?"

Lin Gui answered without turning his head:

"I figured it out myself."

"When you rely on this magic to get around every day, you'll naturally start to figure out how to make it work better."

That's true; the system provided him with a fairly proficient levitation skill.

Lin Gui, on the other hand, constantly explored its limits in actual use.

We will continue to develop its various uses.

Whether it's making a raft float quickly and steadily, or kneading clods of earth that break apart in mid-air back together.

Then Shia reported a new development:

"There are numerous claw marks on the right rock face, about two fingers deep, and the rock is dark red."

Scholars were immediately alerted:

"Bloodclaw Demon territory marker... Turn left immediately, we've deviated from our planned route."

With Shia's night vision and the scholar's geographical knowledge working in perfect harmony.

Lin Gui skillfully maneuvered the train through the dense forest, deftly avoiding several dangerous areas.

When the first rays of dawn pierce through the tree canopy.

They had already passed thirteen important landmarks during the night.

Behind Lin Gui, Eve had already retreated to rest.

The caravan priest Silas was brought in to continue providing magical support.

Betty remained close to Lin Gui, asking new questions every now and then.

While Freya refocused on casting spells, a thoughtful look appeared in her eyes.

The trip that night went much more smoothly than expected.

As the rising sun fully leaped above the horizon.

When the warm golden light shines throughout the forest.

They have safely passed the 21st landmark.

A wooden stake marked with the North Wind Caravan logo.

Freya arrived silently at the front of the car and stood beside Lin Gui.

Her icy blue eyes held a hint of concern, and her voice was much gentler than usual.

"Would you like to take a break?"

This was clearly directed at Lin Gui.

As the main operator of the entire train, he bore the heaviest mental burden.

A full night of intense concentration is enough to exhaust any monk.

In the brief moment when no one was paying attention, Lin Gui lightly swiped his fingertip along his side.

A basic soul spell, [Awakening], silently entered his body.

The fatigue caused by the long spellcasting session vanished instantly, and his mind returned to clarity.

He shook his head slightly and turned to look at the scholar Eli, who was carefully studying the map.

"Can you continue?"

The scholar took out an ancient-looking pottery jar from his backpack, which contained a thick, black liquid.

The liquid looked very much like black coffee, but it had a strange herbal aroma.

It also has a subtle hint of minty coolness.

He tilted his head back and took a big gulp, then gave a gentle smile.

"Well enough."

As he spoke, he gently nudged Betty, who had fallen asleep on his shoulder at some point.

The girl was sleeping soundly when she was woken up, still rubbing her eyes in a daze.

"Go to your carriage and get some sleep first," the scholar said in an exceptionally gentle voice.

Betty nodded blankly, then suddenly leaned forward and gave the scholar a quick kiss on the cheek.

He then staggered toward the carriage, almost tripping over his own robes along the way.

Xia, who was standing nearby, witnessed the whole scene and was so surprised that her eyes widened.

She couldn't help but lean closer to the scholar and ask in a low voice, full of curiosity:

"What exactly is your relationship with that monk?!"

The scholar adjusted his glasses, his gaze behind the lenses gentle and composed:

"A romantic relationship."

Shia's gaze swept back and forth between Betty and the scholar as they walked away.

Recalling Betty's affectionate gesture just now, a hint of envy unconsciously appeared in her eyes.

It's a longing for intimacy, a yearning to express emotions without reservation.

Her fingers unconsciously twisted the hem of her clothes.

His eyes held both curiosity and a hint of unspeakable unease.

Suddenly, she turned around and whispered in Lin Gui's ear.

A warm breath gently brushed against his earlobe, and his voice was deliberately soft:

"I'm tired too..."

Lin Gui didn't turn his head, remaining focused on steering the train through the woods ahead, his tone flat:

"Then go and rest. The sun is up now, and we don't need your night vision anymore."

Shia stomped her foot angrily, her silver hair whipping in a graceful arc in the morning light:

"Hmph! Men, they really have no sense of romance!"

With a nimble flip, she leaped like a light swallow to the last carriage.

The figure quickly disappeared at the carriage door.

The scholar watched this scene, gently pushed up his glasses, and a meaningful smile appeared on his lips.

The morning light fell perfectly on his smiling profile, adding a touch of warmth to the morning.
