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

At this moment, at the entrance to the Naga Dungeon.

The prompts from the rules of the underground palace echoed in Zhang Yun's mind.

Welcome to the Naga Dungeon!

[Single-player mode confirmed, drop rate multiplier: 300%.]

[Given that you have already cleared the dungeon twice, your personal combat power and the power of your summoned beasts will be suppressed by 20%.]

Zhang Yun's body trembled, and he felt much weaker. His brows furrowed slightly.

"The third time we attacked the underground palace, it suppressed my combat power by 20%. That's a significant increase in difficulty."

"but..."

He opened the codex, checked the data of the two main battle beasts, and his brows gradually relaxed.

"With the stacked aura, the combat power can still be maintained at around 800."

"The Little Tyrant's base combat power is 900 points. With the addition of the Evil Aura and the S-level talent Water Elemental Body, even if his combat power is reduced by 20%, his total combat power can still reach around 1500 points."

"With these two treasures by my side, this slight weakening is nothing."

Zhang Yun's lips curled slightly as he gave the skeleton orders:

"Click click, summon the zombie Naga, speedrun!"

"Aim to clear the Naga Dungeon within 20 minutes!"

Click-click—!

The little skeleton nodded, its bone sword slicing through the air.

The void trembled, and a gate to death, constructed from countless white bones, appeared.

The bone gate slowly opened, and the figure of the zombie Naga swam out from it, each of its four arms holding a weapon, its dark purple scales gleaming with a cold, eerie light in the mist.

Hiss hiss hiss—!

It let out a low growl and nestled beside Zhang Yun, instantly giving Zhang Yun an overwhelming sense of security.

"Let's go, let's set off!"

Click-click—!

The little skeleton led the way with its sword, Zhang Yun followed closely behind, and the zombie Naga guarded its side.

The Tyrant Slime continued to rest on his shoulder, emitting soft, even snores...

...

In the blink of an eye, 15 minutes have passed.

The passageway of the second level was illuminated with dazzling light.

Two consecutive exhilarating battles caused both card beasts to simultaneously glow with the light of advancement.

First, there was the little skeleton, clattering.

After it killed the last two-armed Naga, the extremely faint golden runes on the surface of the bones suddenly lit up, like countless golden blood vessels being ignited.

[Ding! Congratulations, Xiao Zhang! Your main Kaka Beast Skeleton Cub has defeated a large number of dungeon projection monsters, raising its rank to Tier 1, Stage 4.]

[Base combat strength increased by 250 points, overall combat strength reaches 1000 points.]

On Zhang Yun's shoulder, the Tyrant Slime, which had been sleeping and paddling in the water, was also glowing and leveling up.

[Ding! Congratulations, Xiao Zhang! Your main character, the Tyrant Slime, has gained a large amount of experience and its rank has been upgraded to Tier 1, Stage 4.]

[Basic combat strength increased by 300 points, overall combat strength reached 1200 points.]

A silvery glow also appeared on Zhang Yun's body.

[Ding! Congratulations, Xiao Zhang! Your Summoner level has increased to Tier 1, Stage 4, and your base combat power has increased to 200.]

[Triggered the Codex's Blessing, stacking 10% of the main card's power, increasing total power to 420 points.]

As the system's voice faded, a powerful force began to grow within Zhang Yun's body.

His life level is still Silver, but his base combat power has reached 420 points with the combined combat power of the two super card beasts!

This is already the standard combat power value of a Tier 1, Stage 4 Gold Card Beast of the same level!

And this is before the addition of the evil aura of the skeleton, Kaka.

If the Evil Aura is added, his combat power will increase to around 550 points!

With 550 combat points at Tier 1, Stage 4, it's enough to overpower any Golden Card Beast of the same tier!

At this moment, Zhang Yun clenched his fist, feeling the surging power coursing through his meridians, and a smile spread across his handsome face.

"In just one day, my level went from Tier 1, Stage 1 to Tier 1, Stage 4. That's incredible speed!"

It's alright.

[After all, you've cleared almost three dungeons and swept through over 300 monsters of bronze level or higher, not even including two gold monsters.]

[An ordinary summoner wouldn't be able to kill this many monsters in a year, so of course you'll level up faster.]

"That's true..."

Zhang Yun picked up the silver Naga card that had dropped on the ground, glanced at its stats, and muttered to himself:

"Including the cards I obtained from clearing the previous dungeons, these two Naga Dungeon Trials have given me 10 Bronze Water Sprite cards, 1 Silver Naga card, 1 Corrupted Naga card, 1 Zombie Naga card, and 1 Four-Armed Naga Gold card."

"It's a pity that two gold cards can't be produced from the same dungeon, otherwise it would be perfect if one more was produced."

Don't be greedy, hurry to the Naga Temple, finish off the boss as soon as possible and call it a day.

"Absolutely!"

Zhang Yun put away the card and led the two card beasts to continue advancing.

Three minutes later, he arrived at the stone gate of the Naga Temple again.

"Zombie Naga, push open the stone door."

Hiss hiss hiss—!

The zombie Naga respectfully accepted the order, her serpentine body slithering forward, her four arms extending to press against the heavy granite door.

Rumble rumble rumble—!

The heavy stone gate was pushed open by its immense force, slowly splitting open to both sides.

Zhang Yun then looked at the little skeleton beside him and smiled:

"Hehe, this time I'll let you take on the final boss alone. Try to finish this quickly."

Click-click—!

The little skeleton nodded blankly, the fire of its soul in its eyes burning even brighter.

It twirled its sword, the tip pointing diagonally at the ground, and stepped into the misty hall first.

Zhang Yun followed closely behind.

The zombie Naga still guarded his side.

The moment Zhang Yun stepped into the Naga Temple, space began to distort, and the sound of waves crashing against the shore echoed.

In an instant, the majestic twelve-armed Naga statue, the stone pillar engraved with ancient inscriptions, and the ankle-deep water all distorted and faded away.

Instead, a dark beach appeared.

The leaden-gray clouds hung so low they seemed to press down on our heads.

The rocks are jagged and covered with slippery, dark green seaweed.

The waves crashed against the rocks not far away, producing a deep and long roar.

Zhang Yun stood on a huge rock, looking around in astonishment: "What's going on?"

"Shouldn't this be the Naga Temple? Where did they go?"

Click-click—!

The skeleton seemed to sense the danger and stood guard beside Zhang Yun, its soul fire in its eye sockets scanning the surroundings warily.

Hiss—!

The zombie Naga also raised her staff, drew her bow and arrow, and became wary of her surroundings.

At this moment, the loli voice of the Codex Elf rang in Zhang Yun's mind, its tone carrying a hint of solemnity:

[Damn it, you've got some issues with your character, you've triggered the Punishment Battlefield.]

You're in trouble, kid.
