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

"Demonic energy is corrupting the monsters!"

"We can't fight this level anymore, we must retreat immediately! Use the teleportation array!"

With a serious expression, Teacher Lu Yan pulled Xiao Zhangqi and prepared to leave.

The term "corrupted monster" was new to Xiao Zhang, and he couldn't help but ask:

"What is this corrupted monster?"

Lu Xueqi's expression was equally solemn, and she explained very quickly:

"The underground palace is essentially a sealing node that suppresses the source of demonic energy. Occasionally, demonic energy seeps out from the cracks in the seal and contaminates the guardian beasts in the underground palace."

"Monsters that have been contaminated not only have doubled combat power, but also a surge in vitality."

"A corrupted silver-rank Naga with two arms is just as troublesome as a gold-rank Naga."

"Every year, many trial participants encounter corruption incidents, and in 90% of cases, there are injuries or deaths among the trial participants."

"We must evacuate the dungeon as soon as possible. If we get entangled by those eight corrupted Naga, the consequences will be unimaginable!"

Upon hearing this, Zhang Yun frowned, showing no intention of leaving.

He wanted to swipe his card more often to buy cards and pay off his high-interest loans, and he didn't want to waste any chance to clear the dungeon.

Teacher Lu saw through Zhang Yun's thoughts and advised, "Zhang, I know you have confidence in Shan Tong."

"But corrupted monsters are completely different from ordinary dungeon projections."

"Your skeleton may be strong, but it can't possibly win against eight golden corrupted monsters. It's no match for them."

"I hope you won't act impulsively or take any risks."

Lu Xueqi also chimed in, "Zhang Yun, if you want to use the gold card, you can exit and choose the single-pass option."

"The probability of a corruption event occurring is extremely low; it will not happen twice in a row."

Before Zhang Yun could respond, the Codex Spirit became restless.

Hehe, the bigger the waves, the more expensive the fish.

While the combat power of corrupted monsters doubles, the probability of obtaining cards increases significantly, and the quality of those cards also improves dramatically.

The value of a Corrupted Silver Card is comparable to that of a regular Gold Card.

With two Mega Beasts in your hand, dealing with eight Golden Monsters is a piece of cake.

[Let the woman take the child and leave; you stay and continue fighting, destroy the entire dungeon!]

Zhang Yun turned to look at Teacher Lu Yan and said sincerely, "Teacher Lu, could you please look after my cousin for me?"

"I want to try and see if I can defeat the eight corrupted monsters."

Upon hearing this, Lu Yan and Lu Xueqi were both stunned.

Xiao Zhangqi panicked, grabbing Zhang Yun's sleeve tightly with both hands: "Cousin, come with me!"

"The teacher said the corrupted monster is very strong, so don't take any risks."

Zhang Yun squatted down, reached out and ruffled his cousin's slightly spiky short hair, and smiled, "Xiao Qi, I have Skeleton Kaka by my side. Even if I can't defeat eight corrupted monsters, escaping won't be a problem."

"You go out with Teacher Lu first, I'll be out in 10 minutes."

"But..."

"Trust in my abilities, okay?"

Zhang Yun ruffled his hair, stood up and said to Teacher Lu, "Teacher Lu, you doubted me when we first entered the underground palace, but I didn't take it to heart. I know you were doing it for Xiao Qi's own good."

"Now, please trust me and look after Xiaoqi for me, okay?"

"this..."

Teacher Lu looked into Zhang Yun's bright eyes for a few seconds before sighing and nodding, "Alright then."

"Since you are so confident, I will not stop you."

"I'll take Xiaoqi out right now and I promise I'll keep a close eye on him, but you have to promise to come back safely."

"Otherwise, I won't be able to explain it to Zhang Qi's mother."

"Okay!" Zhang Yun smiled as he saw the teacher agree.

Lu Xueqi stepped forward and said earnestly, "Zhang Yun, we'll wait for you in front of the stone tablet. Don't keep me waiting too long."

"Very soon."

Zhang Yun gave her an OK sign, then said to his younger cousin, "Cousin, don't just stand there, come with the teacher."

"After we finish clearing the dungeon, let's go get some barbecue together."

"Okay!"

"Go for it, cousin!"

Little Zhang Qi raised his hand, clenched his little fist, and gave Zhang Yun a cheering gesture.

"good!"

Zhang Yun ruffled his hair again, then turned and walked deeper into the underground palace without further hesitation.

Click-click—!

Little Skeleton Kaka also got up and followed his master's steps.

"Let's get out of here quickly."

"Walk!"

Teacher Lu, holding Zhang Qi's hand, and Lu Xueqi, protected by three card beasts, quickly headed towards the teleportation point for the first level...

...

After walking for about 3 minutes, Zhang Yun passed through the gloomy passageway and arrived at the depths of the underground palace.

Deep within the underground palace, the mist was murky and heavy, and the air was filled with a mixture of rotting seaweed and rust, causing Zhang Yun to frown slightly.

[Watch out, a monster is about to appear.]

Zhang Yun stopped and looked ahead.

In the dim light, eight uneven figures slowly emerged from the depths of the mist.

They were once two-armed Nagas.

But now it's almost unrecognizable.

The scales covering its entire body were no longer azure blue, but had been stained a dark purple.

Like a scab formed from congealed blood.

Wisps of black mist seeped out from the edge of each scale.

The black mist twisted and swirled in the air, like living things breathing.

Their eyes are no longer the amber-colored vertical pupils unique to the Naga.

Instead, they were two murky voids constantly emanating purplish-black mist.

The arms cease to be normal limbs starting from the shoulder blades.

Instead, it was a weapon covered in purple crystals.

Some held a coral longbow longer than their own bodies in their hands.

The bowstring was made of some kind of dark-colored tendon twisted together, and when fully drawn, it made a teeth-grinding creaking sound.

Some of their arms transformed into two bone knives covered in serrations.

The blade was covered with writhing black blood vessels.

Some held a long spear made from the entire spine in both hands.

Purple pus was dripping from the tip of the gun.

Corrupted Naga: Water/Dark attribute

[Card Quality: Corrupted Silver]

[Card Beast Level: Tier 1, Stage 5]

Overall combat strength: 550

Although the other seven auras were strong, they posed no pressure to Zhang Yun whatsoever.

Zhang Yun focused his attention on the largest of the corrupted Nagas.

The corrupted Naga was probably the leader, with the most bizarre appearance. Its enormous body resembled a dried-up corpse, yet it was nearly three meters tall, even taller than the Slime Tyrant.

Its arms are not two, but four, with shriveled muscles, like the arms of a zombie.

With bow and arrow in his upper arms and shield and sword in his lower arms, his aura far surpassed that of the other seven corrupted Nagas!

Zombie Naga: Water attribute, Dark attribute

[Card Quality: Corrupted Mutated Silver]

[Card Beast Level: Tier 1, Stage 5]

Overall combat strength: 900

...

Zhang Yun didn't know the strange Naga's combat strength, but he instinctively felt that its combat strength was no less than that of the Frost Dragon Wolf.

If it were just one enemy, Zhang Yun believed that Skeleton Kaka would be able to cut it down.

But... there are still seven powerful corrupted Naga watching us closely, and it seems that the skeletons alone are not enough!

"Coo coo—!"

Just then, the Slime Tyrant's lazy voice rang in his ears, causing Zhang Yun's lips to curl into a slight smile...
