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

[Slime Tyrant: Water-based, Physical]

[Potential: ☆☆☆☆☆☆ (Super Genius)]

[Talent: Tyrant's Aura (S-rank) - Suppresses all card beasts below Dark Gold rank, reducing enemy combat power by 10%-30%; simultaneously ignores enemy attribute resistance, dealing 100% damage]

Overall combat strength: 300+

[Hint: Can be enhanced with the same type of card: 10005/1000000]

[Review: The tyrannical ruler of the slime race, it is no longer a toy for children, but their nightmare!]

[Friendly reminder: Don't mess with it, or it'll break your legs!]

Upon seeing this data, Zhang Yun was utterly shocked!

His gaze was fixed on the overall combat strength, and he said in a trembling voice, "The initial combat strength has reached over 300! That's incredible!"

He knew all too well what that number meant.

The Black Iron Card has a combat power of 10 points at the first level and the first stage. Each level increases the combat power by 10 points, and even at the fifth level of the first level, it only has a combat power of 50 points.

A bronze card has a combat power of 20 points at Tier 1, Stage 1, and only 100 points at Tier 1, Stage 5.

Even if you upgrade to Tier 2, Tier 1, doubling the combat power of a Bronze Card, it will only be around 200 points.

His Slime Tyrant card has an initial combat power that is higher than that of a second-tier, first-stage bronze card, which is truly heaven-defying!

He also learned from textbooks...

The initial combat power of a Silver card is 50 points, while that of a Gold card is 100 points. Even a standard Dark Gold card only has an initial combat power of around 200 points.

And his Slime Tyrant...starts with 300+ combat power!

It has 50% more combat power than a regular Dark Gold card!

and...

It has one SSS-level talent, two S-level talents, three S-level skills, plus six-star potential...

This quality is absolutely amazing!

The Codex Spirit was right—even the worst cards, when upgraded to a high level, can unleash terrifying potential!

And his Slime Tyrant is such an extraordinary card!

At this moment, the Codex Spirit's notification sounded again:

[Ding! Xiao Zhang's main card has been upgraded to Dark Gold tier, activating the "Civil Codex Blessing" talent, increasing his personal combat power by 30 points.]

[Currently ranked as a lower-level Black Iron Summoner, with a total combat power of 40 points.]

As the words of the Codex Spirit faded, Zhang Yun's muscles trembled, and he felt a surge of power growing within him!

Mental fatigue was completely swept away!

An average adult's combat strength is around 5 points.

Adult soldiers who have undergone long-term training can reach the threshold of 10 points.

Zhang Yun, without a main contract card, has a combat power of around 10 points.

And now... he has received a 10% boost to his main card's combat power, which has directly increased to 40 points!

40 points may not seem high, but it's already very close to the potential of a Silver Card Monster!

Silver card monsters are practically invincible to summoners of the same rank when they don't summon cards.

Zhang Yun's class, Class 10 of the first year of high school, struggled to even deal with the first-tier, first-stage Black Iron monsters without summoning cards, let alone the Silver monsters.

Even in the highly competitive Class S of the first year of high school, where geniuses abound, only a handful of students can rival the Silver-ranked monsters of the same level using only their pure human combat strength.

Zhang Yun has only just entered the ranks of summoners, yet he has already gained such powerful combat strength. If this gets out, it will probably shock the entire school!

With this card, even though he's just become a summoner, he has a good chance of passing tomorrow's assessment and entering Class S.

The S-class is a place that can cultivate elite summoners, and there is a very high probability that they will be promoted to a prestigious summoner university in the future. It is a hundred times better than his bottom-of-the-class 10!

but...

When Zhang Yun looked at the advancement requirements of the [Slime Tyrant], he was completely stunned, as if he had been doused with a bucket of cold water!

"The next upgrade for the Slime Tyrant will require a million cards..."

"Looks like I'll need to develop more slimes, and try to get the King Slime and the Sage Slime..."

Now that you have one Slime Card, you should go for the ultimate build and try to collect a million Slime Cards as soon as possible. Only then can you become a powerful Summoner.

Besides... Slime Cards are the easiest card collection in the world. As long as you have money and are willing to spend it, why worry about not being able to collect a million cards?

"That's true..."

Zhang Yun pondered for a moment and said, "The fastest way to make money is to swipe your card in the underground palace."

"The final boss of the Seventy-Two Dungeons is guarded by the projection of a sacred beast. If I can defeat it, I will get a golden card with 100% certainty."

"Sell those gold cards, and you'll easily get hundreds of millions of dollars. Then you can buy as many slime cards as you want."

"However... the underground palace is quite difficult. There are nearly a hundred bronze guardian beasts, and eight silver guardian beasts guarding it."

"Even some of the top-performing students in their final year of high school don't dare to take the course alone..."

"My homeroom teacher also said... that a newbie in the Cast Iron class who tries to solo is doomed. I'm afraid I can't solo it on my own."

Your homeroom teacher was referring to ordinary people.

Although these seventy-two underground palaces are somewhat difficult, they will be very easy for you.

Don't forget, the monster levels in the Seventy-Two Dungeons are all suppressed to below Tier 2. That means... the level of bronze monsters will at most be Tier 1, Stage 5, with a maximum combat power of 100 points.

The Silver Guardian Beast is stronger; a Tier 1, Stage 5 beast has approximately 250 combat power.

[And your Tyrant Slime, with an initial combat power of 300+, can easily sweep away those squishy characters if controlled properly.]

Even if you don't need to challenge the final boss, just clearing out these mobs and getting a few bronze and silver cards will easily pay off your debts.

Upon hearing this, Zhang Yun nodded slowly.

It's virtually impossible for ordinary students to possess legendary cards; they would have no chance of clearing the 72 dungeons.

Zhang Yun possesses a Dark Gold card, which is equivalent to having a cheat code, allowing him to crush lower-tier cards of the same level.

Even if he chooses to go through the underground palace alone, he still has a chance to break through it.

Of course, he could also choose the conservative approach, teaming up with others first to secure a win.

Now that we have a goal, let's take action.

Zhang Yun tucked the cast iron codex behind his back, slung his backpack over his shoulder, and strode out of the classroom...

...

A moment later, he arrived in front of the teleportation tower.

The usually bustling teleportation building was now almost deserted, with hardly a single student in sight.

Zhang Yun knew that his classmates had all gone to the playground to watch the live broadcast of the three giants' adventure in the underground palace.

He walked straight into the teleportation building, but was stopped by the old security guard on duty at the entrance...
