My clan is super powerful

Chapter 97: Unheard-of Black Cards and Spirit Crystal Fragments
Lu Ren looked at Zhang Zhi who was sitting next to him, wondering whether he should come over to express his gratitude.

The rewards they received from this trial of guarding the secret realm were comparable to what they would have received dozens or even hundreds of times.

After all, they persisted until the sixteenth wave. Even if they failed, there would definitely be blue-level items, that is, extraordinary items, in the reward calculation.

For ordinary cultivators who are only at the elite level, items at the extraordinary level are absolutely good things that they dare not even think about.

Zhang Zhi looked at the time and saw that there were still more than twenty minutes left. He felt that the time was about right, so he prepared to call back the treasure hunters he had sent out before.

But when checking, I found that almost all the treasure hunters were gathered in one place.

This made him a little curious.

In this situation, he naturally would not put himself in danger.

He turned around and waved to Fang Min. When he came over, he told him the location of the treasure hunter and the route he had taken, and asked him to go and see what was going on.

With Fang Min's speed, the remaining twenty minutes were enough for him to go back and forth.

Twenty minutes later, Fang Min appeared quietly in front of Zhang Zhi and handed a card to Zhang Zhi with both hands.

Zhang Zhi stared at the black card in his hand for a long time before reaching out to take the card.

Why is this card black?

Or, how come there are black cards?
Gray, white, green, blue, purple, orange, gold, cyan, red, and colorful, each of these colors has a corresponding world level.

Which level of world does this black card correspond to?
Could it be the corresponding world level above the main world?
Or maybe some special card?

He took the card and looked at it. It was dark without any image. There were several rows of white words on the card:
Card Name: A black card with unknown effect.

Card source: Guardian of the Secret Realm.

Card appearance probability: Each time you defend a wave of monsters, the probability of appearance increases by 1.
Card Effect: Unknown.

Note: This card can only be found by Treasure Hunters.

Zhang Zhi was completely confused by this card.

It was the first time he had seen a card with such an introduction, and also the first time he had seen a card without any patterns.

But judging from the probability of the cards appearing as described above, this card is not simple!
The probability of monsters appearing in each wave only increases by 1%. Take this maze secret realm for example. At the beginning of the sixteenth wave, there are 100 extraordinary realm monsters, and the probability of cards appearing is only 16%.

There are one hundred legends in the twenty-first wave, and the probability of a card appearing is twenty-one percent.

The twenty-sixth wave consists of one hundred demigods, and the thirty-first wave of monsters includes a hundred weak divine beings. At this time, the probability of this card appearing is only 31%!

Moreover, this card still requires you to search for it throughout the entire maze while dealing with waves of monsters on one side.

Thinking of this, Zhang Zhi couldn't help but sigh again that he was indeed very lucky!

Just as he was wondering what the black card came from and what it was used for, bursts of roars came from the passage.

He glanced at Lu Ren and the others who were looking at him not far away, nodded at them and said, "I'm ready to leave the secret realm."

After hearing this, Lu Ren and others thanked Zhang Zhi and turned to walk towards the Trial Tower.

After everyone entered the Trial Tower, Zhang Zhi came to the door of the Trial Tower and sat down.

There was no need to rush to leave the Trial Tower. He still had monks here that he had summoned with considerable spiritual power. It wouldn't be too late to enter the Trial Tower after they had killed a few more monsters and were no longer able to hold on.

After all, every monster is worth points!

Besides, the more monsters you kill, the better the rewards you will get in the secret realm.

After about half an hour, there were only about 500 of the 6,000 summoned infantrymen left, more than 200 crossbowmen left, and only more than 10 of the more than 100 Transcendent Realm warriors left. Then he turned and walked into the Trial Tower.

The next moment, he appeared in a huge white space that was exactly the same as the arena settlement space.

The settlement method this time is unexpectedly different from the first time.

What is going on?
But at this time, Zhang Zhi didn't have too much time to pay attention to these details.

Because in front of him at this moment, there was a huge purple box.

Looking at the purple box, Zhang Zhi whistled proudly.

The purple box in the arena last time might have been obtained because the dragon snake let him win, which allowed him to obtain the achievement of being invincible in a hundred battles. The final settlement reward was given to the purple box.

But this time, he obtained the purple reward entirely by his own strength.

With excitement, he rubbed his hands together and reached out to open the purple box.

This time there seemed to be a lot more stuff inside than last time.

Reaching out and touching the first purple card, Zhang Zhi's eyes fixed.
Spirit Crystal Fragments: These fragments are formed from the spiritual crystals condensed from the spiritual power of a great being above the Divine Realm after their death. Usage: Tear the card apart.

Looking at this card, Zhang Zhi's heart was in turmoil.

There are many cards that can be used after being torn open, such as those cards made of elite realm peaches. After the card is torn open, the peaches will directly appear in the hands of the person who tore the card.

Whether or not a card can be torn apart is a choice made by the card maker.

The focus of this purple card is the crystallization of spiritual power.

This was the first time he knew about this thing, but from the description of the card he could tell how precious it was.

What made him feel extremely upset was that this kind of spiritual power crystal fragment could obviously be used directly.

In other words, when you are developing a small world and your mental power is exhausted, you can use these mental power crystal fragments.

This is what made Zhang Zhi feel so upset.

It is obvious that many children from aristocratic families are able to create small worlds because they use these spiritual power crystal fragments.

Previously, in the card slot class, when I heard the instructor talking about the initial number of card slots, I felt that the number of my initial card slots was not that many.

It now seems that many people who have opened up small worlds have used this spiritual power crystal.

Considering that we have rarely heard of anyone directly opening up a medium-sized world, the spiritual power that this spiritual power crystal can provide should not be as much as imagined?
After thinking about it, Zhang Zhi denied this speculation.

For aristocratic families, as long as it can improve strength and potential, if one crystal is not enough, then two will do. For those families that own the masters of the middle thousand worlds or even the great thousand worlds, the crystals that can be obtained by killing the gods are definitely not very precious.

Therefore, the reason why no one has used this spiritual power crystal to directly open up a medium-sized small world is most likely that the use of this crystal has negative effects, or even is harmful to the small world. Only in this way can it explain why no one has used a large number of spiritual power crystals to open up a medium-sized small world.

But even so, the starting point of a Realm Lord who comes from aristocratic family is much higher than that of a Realm Lord who comes from a commoner family.

After thinking for a while, Zhang Zhi carefully put away the spiritual power fragment crystal.

This thing is very important to me and will definitely be useful when I open up the second small world.

I just don't know how much mental power is contained in this piece of mental power crystal fragment. If the amount is large enough, maybe I can integrate it into two purple cards?

But on second thought, he felt that it was impossible. After all, if there really was so much mental power, then the starting point for the children of the aristocratic families would not be a small world, but a medium-sized world.

Also, I must figure out whether this spiritual power crystal has any negative effects, and if so, what are the negative effects.

He remembered that he had one more chance to enter the Sutra Library this month, so he planned to go to the Sutra Library in the library after leaving the Trial Tower to see if there was any information about the crystallization of spiritual power condensed after the death of this god.

After putting away the spiritual power crystal, Zhang Zhi continued to look into the box.

Among the remaining things, the most eye-catching thing was a shining book.

Yes, a real book, not a book card.

Looking at the book, Zhang Zhi felt a little strange. Logically, when calculating the rewards, the Trial Tower gave things that the Realm Master could use. The purple item reward in the first trial secret realm was because it was the spoils of war in the secret realm.

So what is the situation with this book?

Could it be because he opened the door to the world in the secret realm of trial?

Will the Trial Tower calculate rewards based on the trial-taker's behavior within the secret realm?
When I think about it this way, it seems that this is really possible?
Thinking of this, he reached out and took out the tattered and damaged book.

What is strange is that as soon as this book left the settlement treasure chest, the faint light originally emitted from the book began to slowly dissipate and turned into a normal book.

That book was indeed related to the door to the world he opened inside the Trial Tower.

The name of this book is "On How to Accelerate the Growth of Small Worlds through the World Gate"

Zhang Zhi flipped through the pages and read the first part, which was very useful to him!

Still in the reward settlement space, Zhang Zhi didn't read it carefully. After flipping through it roughly, he had a general understanding of the content of the book.

To him, the importance of this book is probably no less than obtaining the second world seed.

Because the main content of this book is about accelerating the development of one's own small world by devouring other small worlds.

This completed the last link of his great idea:
As long as your own world is strong enough, you can make your own world stronger by devouring other worlds that are weaker than your own world. If you can continue to devour like this, it is not impossible to directly devour the main world of the alien race in the future.

Of course, this must be subject to a lot of restrictions. Otherwise, with so many people in the main world of the Realm Lord, someone would have done it long ago.

But no matter what, the appearance of this book proves that it is feasible to devour other worlds, which is enough for Zhang Zhi.

Even if there are more restrictions, we will find a way to break through when the time comes.

The gains from this trial in the secret realm were beyond my expectations.
