Although it is a bit shabby, this heroic spirit is super strong

Xiao gently rubbed their heads.

"Why do you seem not surprised?"

Lucy asked Xiao with some confusion.

"That's because I knew from the beginning that you two were secretly following me."

"Uh…"

"Although I was teasing you, I really meant what I said."

Xiao hugged the two sisters and whispered softly in their ears.

"You, you are really helpless."

Lucy blushed and hugged Xiao.

"Sister, you are so cunning."

Rose also quickly hugged Xiao.

Looking at the three of them clinging to each other, Crystal smiled helplessly.

A person stepped back alone.

*

After three days of exploration, Xiao and his friends arrived at the seventeenth floor of the Crystal Valley.

Just as Crystal had guessed, there were no magical beasts here.

"Well, now we have to find a way to find that hidden area."

"Well, did Kyle tell you any clues?"

Crystal asked Akatsuki.

"It is said that anyone who has seen the dragon egg will feel extremely tired."

"Yeah, it's the same thing I found here."

"Another thing is that it is said that this dragon egg is sealed in a crystal."

Xiao thought for a moment and added to the others' thoughts.

"Sealed in crystal? How can the dragon egg hatch like that?"

Crystal was very skeptical about this information.

The hatching conditions for dragon eggs are very harsh.

In addition to the general requirements for temperature and humidity, the magic power requirements for hatching different dragon eggs also vary greatly.

The higher the level of the dragon egg, the more magic power it requires.

This is also the reason why the dragon clan, the top dragons in this world, although has a strong reproductive capacity, is still extremely rare in number.

There are even dragon eggs in the tribe that cannot be hatched because they cannot find enough magic power.

"Is it possible that the crystal is used to collect magic power?"

Lucy asked on a whim.

"I didn't expect you to be so smart."

Xiao rubbed Lucy's head.

"Hey! What do you mean by that?"

"But as far as I know, there shouldn't be any crystal that can do this."

Crystal objected.

"There's a kind of crystal that might be able to do this. It seems to be called the Demon Sealing Stone?"

Rose tried to remember the words in Louisiana.

"Demon Sealing Stone?"

"Ah, that thing is called the Ouran Magic Stone in ancient dragon language."

"Well, just like what Brother Xiao said. That kind of crystal can be used to store magic, but the method of extracting magic power is very complicated, so..."

"Rose, where did you get this knowledge?"

"Eh? I, I..."

"dawn?"

"Why are you looking at me suddenly?"

Xiao noticed that Crystal's scrutinizing gaze fell on him and felt very innocent.

"Do you need me to explain the reason?"

"Well, since we speculate that there's a large Demon Sealing Stone in the hidden area, how do we find it now?"

"Um…"

Crystal knew that Rose was deliberately changing the subject, so she stopped pursuing the matter.

"If we use crystal powder rich in magic, we should be able to determine the general direction of the hidden area, right?"

Lucy suddenly realized that they had been within the range of the Demon Sealing Stone since they entered the seventeenth floor.

If a large amount of crystal powder is spread on a large area of ​​ground.

Due to the different effects of magic absorption at different distances from the magic-sealing stone, the different magic content of crystal powders should be clearly visible.

"Yeah, but that would take too much time."

"Woo! Rose, can't you give me a little face?"

"Although the method is not good, the idea is surprisingly good."

Crystal suddenly had an idea and gave Xiao a wicked smile.

She put a metal ring on Xiao's head and hung a blue crystal around it.

"puff!"

"Sister, even though it's funny, you can't laugh."

Rose whispered to stop Lucy.

"Rose, your words are even more hurtful. So what's going on?"

"When this crystal receives more than a certain amount of magic power, it will move in the direction opposite to the source of the magic power. Just try to release a little bit of magic power until I tell you to stop."

Crystal explained while holding back a laugh.

The effect of the magic stone decays by a percentage with distance.

As long as the magic source is strong enough, even a small area can produce a significant difference in magic concentration.

"Well, release some more magic power. Okay, remember to release this much magic power next time."

Crystal looked at the obvious difference in the crystal's floating state and smiled with satisfaction.

"Let's explore in that direction next."

Chapter 29 Agreement

"Why does it feel like this hidden area is moving?"

Crystal looked at the 'wreath' on Xiao's head and complained dissatisfiedly.

They seemed to be going around in circles on the 17th floor for the three days they were there.

Looking at the familiar campfire ashes beside her, Crystal knew that they had returned to the cave from the day before.

"Maybe it does move. Yeah, I have a question."

"Huh? You say."

"Why do you say the dragon egg on the 17th floor is a legend?"

According to Xiao's memory, Kyle knew that this dragon egg did exist.

He also seemed to know how to get to that secret area.

But Kyle didn't think about this at the time, and Xiao had no way of knowing his method.

"That must mean no one has seen the dragon egg yet."

Crystal recalled for a moment and began to tell Xiao and the others about the history of the Macaulay family.

It seems that adventurers discovered that area about two hundred years ago.

The head of the Macaulay family at that time wanted to obtain the dragon eggs, so he spared no expense to recruit a large number of adventurers.

It is said that there are 5 S-rank adventurers alone.

The head of the family took these adventurers and his own confidants to the Crystal Valley and never returned.

Since then, no adventurer has discovered that area in Crystal Valley.

"That's probably the legend."

"Then how did Kyle know how to get there? Why didn't he just take the dragon egg?"

Xiao found it very interesting and smiled meaningfully.

"Uh... I have a bad feeling about this."

When Lucy saw Xiao's expression, a chill ran down her spine.

"Rose, take out the magic gun."

"Eh? Ok, ok."

"Ah, as expected."

Lucy looked at her sister, who was very excited and holding a silver rifle-like weapon, looking eager to try it out.

"Perhaps there is no entrance to the secret area at all, and we have been misled by you, girl."

"Eh? Blame me..."

Crystal looked very innocent when Xiao tapped her head.

"Just kidding."

"You guy!"

Looking at Xiao's playful smile, Crystal felt very annoyed.

"I remember there was a toad on this floor that could shoot lasers?"

"Um... that's called the Aurora Toad, a very dangerous monster."

"Yes, that's the thing. I guess it blew the entrance open."

"But why are we... Could it be that these walls can also..."

Crystal suddenly realized a problem.

The crystals and minerals in the Crystal Valley can regenerate out of thin air, so why can't these stone walls?

Furthermore, ever since the decline of Macaulay County two hundred years ago, fewer and fewer adventurers have been able to reach the 17th floor.

Anyone who can defeat the Aurora Toad...

"Well, that's what happened. Since no one cared about these worthless stones, you overlooked this matter."

"Hey! You..."

Crystal blushed and felt very embarrassed.

"Rose, just do it!"

"okay!"

The girl's fair face flushed slightly as she raised her magic spear.

A loud bang caused the cave to shake violently several times.
