Card Kingdom: This kid's codex is full of gold

Rumble, rumble, rumble.

The heavy stone door was pushed open by a tremendous force and slowly cracked open to both sides.

As the gap in the door widened, a vast, circular hall slowly unfolded before Zhang Yun's eyes.

Click-click—!

The little skeleton, Kaka, took the lead, sword in hand, and stepped into the main hall to serve as Zhang Yun's vanguard.

Coo-coo—!

The Slime Tyrant pushed the stone door open to about half a meter, then stopped and followed the little skeleton into the hall.

Zhang Yun followed closely behind.

The four-armed zombie Naga stood guard closely beside Zhang Yun.

As soon as Zhang Yun stepped into the main hall, he smelled a strong scent of aquatic plants.

He looked directly in front of the main hall.

A colossal twelve-armed Naga statue, hundreds of feet tall, stands majestically, its entire body covered in dark green aquatic plants.

Although it is just a statue, it is as lifelike as if it were alive.

The profound aura emanating from it made Zhang Yun dare not underestimate it in the slightest.

At this moment, the stone door behind them was slowly closing.

The giant Naga statue's eyes also lit up with a brilliant blue light, like two lit lanterns.

Blue light, like tears, flowed from its eye sockets, like a luminous stream, slowly converging towards the ground.

Buzzing—!

As the blue light converged, an arrogant figure slowly emerged from the light.

Her upper body was human, with a beautiful and bewitching face, her features so exquisite they were almost unreal, and a golden crystal core embedded between her brows, emitting a soft blue light.

Four slender arms, gracefully outstretched at the sides, like slowly opening an ancient folding fan.

Its lower body is a snake tail that is several meters long, covered with golden scales, and the tip of the tail is triangular and as sharp as a knife.

It is the final guardian boss of the Naga Dungeon—the Golden Naga.

[Golden Naga Projection: Water-based, Physical]

[Card Quality: Gold]

[Card Beast Level: Tier 1, Stage 5]

[Potential: ☆☆☆☆☆]

Overall combat strength: 920 (+92)

At this moment, the Golden Naga tilted her chin up, looking at Zhang Yun and the others, a contemptuous sneer curling her lips:

"A cast-iron reptile, how dare you challenge this local temple?"

"He's courting death!"

Hearing her contemptuous words, Skeleton Crack and Tyrant Slime both had a faint rage burning in their eyes.

They will not tolerate anyone mocking their owner!

Click-click—!

Coo-coo—!

Without exchanging any words, the two monsters simultaneously stepped forward and approached the four-armed Naga.

The zombie Naga guarding Zhang Yun's side also raised their longbows, aiming them at the four-armed Naga.

Zhang Yun smiled slightly, picked his ear with his little finger, and said with a laugh:

"You think you're so great? When you're in this business, numbers matter."

"Four against one, how can you win?"

"Hmph, mere ants. Even if a hundred or a thousand come, they'll only be there to mark their heads."

Golden Naga was full of confidence in her strength.

She raised one arm, her hand lightly clenching, and a deep blue longbow appeared in her palm.

She raised her arms again, her hands clenching lightly, and held a blue staff and a serpentine longsword in her palms.

The Golden Naga not only possesses powerful ranged attack and spellcasting abilities, but also boasts formidable melee combat capabilities.

It is considered the most troublesome guardian beast among the three underground palaces in Jiangcheng.

However, her aura was still too weak to suppress the little skeleton and the slime tyrant.

Click-click—!

Seeing that she had conjured a weapon that could potentially threaten its master, the little skeleton Kaka could no longer restrain itself.

With a push of its short legs, it transformed into a golden flash and shot towards the Golden Naga.

"How dare you, mere ants, be so insolent!"

The Golden Naga snorted coldly and unleashed a blue arrow.

This arrow was terrifying, like an aurora borealis, moving so fast that it was difficult for the naked eye to catch, and it shot straight at the little skeleton's face.

The little skeleton didn't dodge at all, heading straight for the blue arrow.

Bang!

Just as the blue arrow was about to hit the little skeleton, it suddenly exploded, turning into countless water droplets that spread outwards.

The golden Naga's jewel-like pupils contracted, and she turned to look in Zhang Yun's direction.

There, a four-armed Naga, resembling a zombie, held its longbow high and fired an arrow that blasted away her arrow beam!

"Damn corruptors!"

"You should stay in hell!"

Enraged, the Golden Naga raised its longbow and aimed it at the Zombie Naga.

Suddenly, a whooshing sound rang out, and the skeleton had already charged right up to it.

唆！

With a tremor of its bone sword, it slashed towards the abdomen of the Golden Naga.

"hateful!"

The Golden Naga dared not be careless, and swung her serpentine longsword, slashing at the skull's crackling sword light.

Ping!

The bone sword collided with the serpentine longsword, creating a ripple in the air that spread outwards.

The two were evenly matched!

The Golden Naga's pupils contracted sharply, becoming pinpoints in size.

Clearly, she hadn't expected that this lowly skeleton soldier would possess such strength, capable of directly confronting her.

This made her feel that her dignity had been insulted.

"Water roars!"

She raised her arm holding the staff, gathered water-based soul power, and unleashed a wave of water at the small skeleton that was right in front of her.

At that moment, the Slime Tyrant charged in.

Coo-coo—!

It let out a deafening roar, and dark blue energy frantically gathered in its right fist, unleashing an explosive punch with all its might!

"ah--!"

The Golden Naga sensed the terror of its punch and quickly aimed its staff at the Slime Tyrant, attempting to cast a spell to blast it back.

However...

With a deafening roar, the water wave emitted by the Golden Naga was shattered by a single punch from the Slime Tyrant.

An explosive punch, exceeding four digits, slammed into the Golden Naga with unstoppable force.

boom--!

The golden Naga was instantly blasted away, tumbling and falling backward.

She was thrown more than ten meters away before she finally managed to stop herself.

She roared as she rose to her feet, ready to retaliate, when suddenly... a flash of sword light grazed her neck, freezing her beautiful and alluring face in an instant.

"How...how is this possible..."

Her gaze began to dart around, and her beautiful yet aloof head rolled off her neck.

Before her head even touched the ground, a small, skeletal foot kicked out and landed squarely on her cheek.

Snapped--!

Her head, like a soccer ball, traced an arc before crashing heavily to the ground.

After rolling several times, her head landed at Zhang Yun's feet, face up, meeting Zhang Yun's gaze as he looked down at her.

Zhang Yun looked down at her, a smile playing on his lips, and asked:

"With only one head left, are you still so tough?"

The golden Naga's vertical pupils were filled with disbelief, and her lips parted slightly, emitting a hoarse and weak voice.

"How can your card beast be so strong..."

"You're clearly just a piece of cast iron trash..."

Zhang Yun raised his right foot and gently stepped on her head.

His voice wasn't loud, but every word reached the Golden Naga's ears clearly: "Is it possible... that you, so arrogant, are even more useless than me?"

"Damn human, how dare you humiliate me..."

A flash of anger appeared in the four-armed Naga's vertical pupils, and she cursed in a low voice, "If you dare to set foot in this palace again, I'll make you regret it..."

Before she could finish speaking, her head transformed into a radiant blue light, slowly evaporating along with her mangled body lying in the water.

A card gleaming with golden light slowly rose from the radiance and hovered in front of Zhang Yun.

On the card, a four-armed Naga holds a longbow, a staff, and a serpentine longsword, with the serpent's tail coiled around it, and its vertical pupils still show resentment.

Zhang Yun reached out and took the gold card, then began to examine the data...
