Wizard: My skills can be upgraded indefinitely.

Welcome to Cola Novels! A vast collection of novels awaits your exploration!

As night deepened, the core area of ​​the Shadow Moon Tower was revealed.

The surroundings were silent; most of the lights in the residential area and wizard dormitories were off, with only a few scattered magical lighting runes emitting a faint glow.

Beneath the seemingly peaceful night sky, a deep gray shadow is silently moving about.

Gaga shrank to the size of a palm, and the color of its feathers, adjusted by its active abilities, almost blended into the surrounding shadows.

Only a pair of heterochromatic eyes remained, gleaming with a cunning light in the darkness.

"The shadow is deepest under the statue on the left, and the moonlight just barely reaches through the crack in the window on the right—perfect!"

It muttered to itself silently while gripping a small leather strap tightly with its paws.

This is a small leather pouch specially made by Ian, sealed with shadow energy.

The bag contained its "mission" for the evening.

Dozens of tiny strips of paper, made of a special material, will quickly spontaneously combust and turn to ash when exposed to strong light or active detection.

The contents of the note were dictated by Ian and then "written" by Gaga using his claws to draw upon shadow energy.

It actually looks more like scribbles, but the key information is clear.

The content was carefully designed, greatly exaggerated while incorporating some real clues.

The aim was to create a sensation and alert higher-ups.

[Warning! The spy in the shadows: Signs of infiltration by the 'Twilight Eye'!]

These worms in the shadows, who worship twistedness and depravity, have quietly infiltrated the shadows of my tower!

They pry into secrets, spread whispers, and attempt to corrupt the pure heart of the wizard!

Beware of the shadowy wizards around you who behave strangely!

Be wary of unusual shadow fluctuations in certain dark areas, such as near the abandoned meditation tower in the East District, underground drainage pipes, etc.!

For the sake of the tower's purity and peace, please convey this message to a trustworthy mentor or deacon...

A kind person who wishes to remain anonymous.

"Heh heh, 'worm in the shadows,' Ian used that word perfectly; it sounds disgusting and scary!"

It flapped its wings triumphantly, almost falling out of the shadow of the eaves where it was hiding, and quickly steadied itself.

Our first stop is near the bulletin board outside the novice wizards' common room.

This place is bustling with people during the day, but deserted at night, with only a few magical cleaning golems silently sliding around.

Gaga spotted a puppet turning a corner and darted like a shadowy lightning bolt behind the bulletin board.

It deftly pried out two strips of paper with its claws and carefully stuffed them into a crack in the bulletin board, leaving only a tiny corner sticking out.

"Here, the first little wizard to arrive tomorrow will definitely see it, ga!"

The second stop is at the intersection of corridors leading to several senior wizard laboratories.

The ground here is inlaid with glowing guiding runes, but the reliefs high on the walls cast deep shadows.

Like a real fallen leaf, it drifted with the slight change in the airflow to the shadow of a stone eagle sculpture.

It folded a strip of paper into a small triangle and cleverly wedged it into the groove below the beak of the stone carving.

"There are a lot of formal wizards coming and going here; maybe one with good eyesight will spot them, haha!"

The third place... the fourth place...

It worked in such a furtive and enthusiastic manner.

On the secluded top of a library bookshelf, in the crack of a fine restaurant's serving window, or even on a wizard's path where he's keen on night patrols...

These places all became locations for it to distribute "kind-hearted people's flyers".

Every time it successfully launches a product, it mentally records a credit for itself.

"Another one! Perfectly concealed, undetected! The Shadow Messenger, Lord Gagga, is on the scene—one against two!"

Throughout the entire process, it relied entirely on talent, moving and hiding in the shadows, without using any magical energy that could be tracked.

Their movements were nimble, yet tinged with a cautious excitement.

Occasionally, night patrols would pass by, or they would sense mental energy sweeping across from afar.

It immediately curls up into a ball, completely assimilating into the shadow of the wall or the ground, even stopping its breathing.

Only a pair of tense yet excited eyes darted around until the danger passed, before darting to the next target.

The last note was placed inside a vent connecting multiple faction areas.

Gaga quickly evacuated the core area, quietly slipping back to Ian's residence along a pre-planned route.

It slipped through the window crack, broke free from the shadow assimilation, and returned to the size of a normal crow.

It landed triumphantly on the alchemy table, its voice low but unable to hide its excitement as it looked at Ian, who had just opened his eyes from meditation.

"Mission accomplished, Ian! All the notes have been placed in well-hidden locations, ensuring they will be discovered unintentionally!"

In a few days, those 'insects' will definitely have some interesting expressions, cackle cackle!

It mimicked and imagined the furious state of the Twilight Eye members.

I jumped a few times on the platform, excited and filled with the joy of playing a prank.

……

Early morning, under the bulletin board.

A young female apprentice happened to glance at the corner and caught a glimpse of the note peeking out.

Driven by curiosity, she painstakingly pulled it out and unfolded it, initially just glancing at it casually.

Immediately, her eyes, which were slightly tired from staying up all night, widened instantly.

Shadow worms, twisted worship, mind pollution...

These chilling words made her heart skip a beat.

She glanced around instinctively, and seeing that no one was paying attention, she quickly crumpled the note into a ball and stuffed it into her robe pocket.

However, she couldn't concentrate on her studies all day.

Those words kept swirling in her mind, making everyone seem like they were hiding secrets.

Finally, after a potions class, she pulled aside her best friend.

He quietly repeated the contents of the note in the corner, his voice trembling as he finished.

"...Do you think it could be true?...That thing...could really have infiltrated the tower?"

One day later, the eagle-shaped stone carving groove.

A middle-aged potion master, who was used to pacing and thinking, subconsciously placed his hand on the familiar stone eagle sculpture, and his fingertips suddenly felt a little strange.

He took out the triangular piece of paper and unfolded it, his gaze quickly sweeping over the alarming warnings.

"A worm in the shadows...some darker areas..."

He snorted coldly, a dismissive smile playing on his lips. "A bunch of nonsense."

He casually burned the note into a wisp of smoke, then continued pacing as if nothing had happened.

But back in the lab, he couldn't help but glance out the window a few more times at the direction of the abandoned meditation tower.

Even though he told himself it was just a silly joke.

The underside of potted plant leaves.

One of the first-level wizards in the council, feeling tired after processing a batch of violation reports, got up and went to the door to get some fresh air.

He habitually fiddled with the leaves of the pot next to the door, but his fingertips unexpectedly touched a rough, foreign object.

He tore off the strip of paper attached to the back of the leaf and quickly scanned it in the dim light coming through the room.

Shadow worshippers, lurking, the corruption of the wizard's heart...

These words made his already tense nerves jump.

He immediately scanned the corridor around him, then carefully smoothed out the note, folded it neatly, and cautiously tucked it into the inside pocket of his robe.

The next morning, the note lay quietly on the boss's desk.

……

Rumors began to spread slowly and inevitably, like a trickle in a dark ditch.

It began as cautious whispers in a corner of the apprentices' lounge, during the brief tea breaks of the lower-ranking wizards.

"Have you heard? The members of that organization hiding in the shadows... are inside the tower."

"My brother's friend is in the Shadow faction, and he said they've heard rumors about it too..."

"An apprentice went missing recently; it must have been them, those damned worms!"

"It is said that the deacon council has already begun a secret investigation."

"Don't talk nonsense, it's probably just some guy's prank."

However, as the identities of the discoverers increased...

From an anxious apprentice to a skeptical low-ranking wizard, and finally to a full-fledged guard on patrol duty.

The rumors gradually gained corroboration, with statements such as "the information is reliable" and "someone within the deacon council has confirmed it."

The atmosphere in the entire tower began to tense.

Some people have become more vigilant and can't help but quicken their pace when passing through certain areas.

Some people scoffed at this, seeing it as pointless intimidation or a tactic of factional infighting.

Others began to scrutinize their colleagues, whose movements were somewhat mysterious or who dealt more with shadow energy, with caution and even suspicion.

Above the towering spire, the clouds surged silently.

In a top-floor room, a note that had just been handed in was angrily torn to shreds.

"Damn it, who is it...?"
