Hello, is this a letter addressed to Demon Fortress?

Lin Gui nodded.

"Yes, that's me."

"What can I do for you?"

The old man did not answer.

He stroked the two upturned tufts of his mustache, his gaze sweeping over Lin Gui with a scrutinizing curiosity.

He sat on the bench, his back slightly hunched.

The gray robe he was wearing had been washed until it was almost white, and there was still a little ink stain on the cuffs.

He looked no different from any other ordinary old man.

"Could you... let me take a look?"

"Let me see your levitation skills."

Lin Gui did not refuse.

He raised his right hand, palm up, fingers slightly spread.

On a counter in the distance, an ink bottle swayed slightly.

Then the entire bottle detached from the table, floated steadily over, and landed in his palm.

The entire process was completely silent.

Without the aid of a staff.

Not a single syllable escaped his lips.

He didn't even move his shoulder.

The old man's eyes lit up instantly.

He suddenly sat up straight on the bench.

That lazy, old-fashioned demeanor vanished, and he stood up straight.

His sharp gaze swept over Lin Gui's body, as if trying to see through his skin to discern the flow of magic within him.

"One more time."

Lin Gui returned the ink bottle to the counter, and when the bottom of the bottle hit the wooden surface, it made only a very faint thud.

"Again."

Lin Gui made the ink bottle circle the room, tracing a smooth arc.

"Again, again!"

Lin Gui simply spun the ink bottle around the old man's head three times.

It maintains the exact same height and speed with each rotation, without the slightest difference.

Each spell was cast completely silently.

There were no incantations, no gestures, and no violent fluctuations of magic.

The ink bottle seemed to be held up by an invisible hand, floating lightly in the air.

As Lin Gui's thoughts moved.

Sometimes fast, sometimes slow.

It is as agile as a fish swimming in water.

The old man's eyes widened and his body straightened.

His hands, resting on his knees, unconsciously gripped the fabric of his trousers.

Just as Lin Gui was casting his spell for the fourth time.

A powerful burst of wind magic suddenly erupted from the old man's body.

An invisible current of air instantly filled the entire post office lobby.

The magic lamp was blown around violently, and the letter bags hanging on the wall rustled and swirled.

Those wind elements are like nimble tentacles.

They surged toward the direction of the forest ghost, searching for traces of the spellcaster.

The old man used his magic to try to capture traces of Lin Gui's spellcasting, but inadvertently revealed his own identity.

Almost every mage who reaches the extraordinary level will completely lock onto their major magical direction.

This is especially true for higher-ranking mages.

The old man's wind magic was so pure, and his control over the wind element was extremely strong.

She even surpasses Freya, a mage who specializes in wind and ice magic.

In the Thousand Towers, there can only be one legendary figure of the wind element.

Wind-type Tower Master.

Lin Gui raised an eyebrow.

The other party's casual demeanor just now was completely inconsistent with the attire of a revered tower lord.

Although he knew the other person's identity, he did not expose him.

Captured by the old man's wind element, he cast the levitation spell again.

This time, he deliberately slowed down the flow of magic.

This allows those wind-elemental beings to clearly capture the entire process of magic flowing from the core circuit to the casting node.

Like a slowly unfolding thread, extending little by little from the source to the tip.

The old man squinted.

His gaze was fixed on Lin Gui's hands.

It's like tracking an invisible line.

They even held their breath, afraid of missing any tiny detail.

"There is no spell."

"No gestures."

"Even the fluctuations of magic power have been suppressed to a minimum."

"The magical flow of the loop is perfectly natural."

"How did you do that?"

His voice carried an barely suppressed excitement, with a slight tremor at the end.

"The levitation spell is only a basic magic."

"But its magical flow path has at least eighty-seven points that require incantations to guide it to operate stably."

"You completely skipped these induction steps and directly used the magic core to drive the magic circuit."

"It made 87 turns in an instant?!"

"How is this possible?"

"To what extent has your control over magic reached a certain level of precision?"

"How long have you been studying?"

"Who taught you that?"

He spoke faster and faster, becoming more and more excited.

My body involuntarily leaned forward.

A near-greedy thirst for knowledge surged in those old eyes.

Lin Gui did not answer.

He simply crossed his arms and looked at the old man's face, which was slightly flushed with excitement.

He leaned back casually in the chair, his posture relaxed.

"Compared to this..."

"Shouldn't you tell me who you are first? What brings you here so late at night?"

The old man's open mouth froze.

His upper body, which was almost touching Lin Gui's face, suddenly stopped, and even his eyes paused for a moment.

He blinked twice, then blinked twice more.

Then he suddenly took a step back, coughed dryly, and the hem of his robe rose and fell with his movement.

He straightened his collar, straightened his back, and put his hands behind his back.

He forcefully suppressed his excited expression.

He adopted a deliberately dignified demeanor, his facial wrinkles tightening even more.

He stroked his beard, cleared his throat, and spoke in the most solemn tone possible.

"cough."

"I am the Tower Master of the Wind Tower in the City of a Thousand Towers."

"The legendary wind mage, Wayne Gale."
