If it’s convenient, could you explain why?”
Wu Tong and Mu Xing waited for a long time, but Opela never gave a reason.
In the end, Wu Tong only took the initiative to ask.
Pella sighed and threw away the black crystal that she had been favoring for a long time.
It was no different from throwing a stone.
"This is the secret of our temple.
I tell you, you must not go out." ” Opera seemed to have spent a lot of effort before she made up her mind to tell Wu Tong and Muxing her so-called secret, but before Wu Tong could swear, she continued: "In our temple, there are actually always It's something like a crack in space, and we don't know what's inside.
Someone once went in, but never came out.
However, shadow energy will continue to spurt out from the cracks.
If you practice around the cracks, you will get twice the result with half the effort.
Of course, you will also be sucked in by the cracks. , it depends on personal luck.”
In fact, this is not the first time Wu Tonglai has heard about Opera's mystery.
Because there is also a crack in the seabed, which is where Tambiju is, where the mermaids' temple is located.
Its expression is similar to that of Opela.
The water element there is very abundant, but the crack is inaccessible and will be washed away as soon as it gets close.
Although the mermaid held it very high and called it the Eye of the Ocean.
But it seems that the mermaids don't like to go there, and Wu Tong doesn't know why.
"What does that have to do with the black crystal?"
"It is because it would be more dangerous to practice there, so we wanted to find a safer way, which is to use the huge shadow energy to condense the crystal.
So we have been thinking of a way, and I almost succeeded."
The "almost" coming to Opela was the problem.
"It's difficult to condense pure shadow energy, so someone thought of using other things to reduce the difficulty.
Anyway, what we need is safe energy, but we don't need how pure the energy is.
Then we looked for a lot of things Doing experiments, and finally found something called a rock spirit," Opela continued.
"What is that rock spirit?"
"Actually, I'm not sure.
This happened a long time ago.
Anyway, using this kind of thing, you can condense crystals very smoothly.
It seems that this kind of thing can crystallize any object.
According to the records of our temple, At that time, a lot of black crystals were obtained.
Everyone was very happy and planned to send the black crystals to various temples so that the priests could practice faster.
However, the high priest at that time was a very cautious person.
I arranged for a few young priests to try it out, and the result was " "What's the result?"
Although he knew that Opela was deliberately showing off, Wu Tong couldn't help but ask.
"It went very well at first.
This kind of artificial crystal is almost no different from naturally formed crystal.
But just when the high priest was preparing to promote it, an accident happened.
The priest who had made the most progress one day after practicing, was far from being able to Get up."
If you win, just go straight.
I'm curious how you can destroy it with this kind of crystal."
Opela stopped at the critical moment, Wu Tong could only cooperate.
"It's not that it fell, but his lower body has also solidified, just like a stone.
No matter what method is used, his body cannot be restored.
From then on, he can only stay in that state until death."
"Is the irreversible petrification caused by that rock spirit?"

"We can't think of any other reasons.
In the end, the high priest had some animals caught and fed them rock spirits.
As a result, they all turned into stones, and they were all sexual.
Now it's clear, Using crystals made by rock spirits to practice will not only absorb the shadow energy, but also absorb those rock spirits, which will cause the cultivator to be petrified.
Therefore, the high priest had to destroy those black crystals, leaving only some, in order to allow us descendants to distinguish between real black crystals and black crystals mixed with rock essence, and these should all contain rock.
There are so many black crystals.
I would rather be less powerful than turn into stone."
Opela pouted.
"Haha, you should feel lucky.
If your predecessors hadn't paid the price with their lives so that you could distinguish these black crystals, you would have been miserable.
Think about it, if your grandmother really brought people to dig, what would happen to you?
The temple is finished.”
In fact, this is the so-called importance of experience and lessons.
No matter how powerful a person is, he cannot know everything.
Inheritance is the basis for the continuation of a race.
Opera could afford to pick them up and put them down.
Now that she knew these black crystals were unusable, Opera no longer cared about them and didn't even take one as a souvenir.
In her own words, the body will absorb the shadow energy involuntarily, and it is likely that the rock spirit will also be absorbed, so it is safer to stay away from these black crystals.
Unfortunately, Opela has never been able to get too far away from these black crystals, because the ends of the second, third, and fourth passages are all places covered with black crystals.
Although they should not be tired, this monotonous and repetitive work still greatly consumed the energy of the three people.
In the end, everyone lost the energy to talk and just hurried on.
Thinking that the passage at the back would definitely be longer than the previous one, the three of them really looked sad.
But just after arriving at the end of the passage for the fifth time, the scene in front of him finally changed.
This is no longer an opera hall, but more like a huge black crystal camp, like a large mine, which is as big as dozens of football fields.
Looking around, everything is densely covered with black crystals and shadow auras.
It's so rich here that even Wu Tong feels a little depressed.
"Although I still haven't found the right one, this place is really big.
Why don't you light up the lamp?
It must be very beautiful."
Opela sighed.
Regardless of whether these black crystals are useful or not, this place is really spectacular.
Your sister Muxing, what is she doing?"
Wu Tong looked annoyed.
Probably because she walked too far and never encountered anything, Opera had relaxed.
Duixing, on the other hand, remained alert.
Although his vision was affected, he still tried hard to observe the surrounding environment without relaxing at all.
"Well, hehe, I can't compare with Sister Muxing."
Opela stuck out her tongue unhappily, and then tried to think around.
It didn't take long for Opela to know why Wu Tong didn't do it this time.
Lighting up.
Because it is obvious that there is an area in the distance where the crystals have traces of being mined.
Many crystal pillars are broken from the roots.
This cannot be naturally formed.
"Don't make any noise, let's get through."
Wu Tong whispered.

After saying this, he spread his wings slightly and floated, moving forward slowly in mid-air.
As expected, there was no sound at all.
Opera and Muxing also used Wu Tong's body as a cover and slowly moved forward.
However, what is disappointing is that although the traces of mining there are obvious, it has been a while, and I don’t know if it has been abandoned or if it was only intended to be mined once.
"No matter who it is, what do they want these black crystals for?
Aren't they afraid of being petrified?"
Opela was puzzled by this.
Judging from the conditions of the surrounding crystals, the amount of black crystals taken away by mining was really small.
"Maybe there are some things that can use these crystals.
The world is full of wonders."
Wu Tong thought of those people and black ants.
Two completely different species can coexist peacefully, obviously they need each other, which is a mutually beneficial behavior.
If those black ants can digest this kind of black crystal and people can help mine it, they can accept the whereabouts of these crystals.
Black ants possess formic acid, which may be able to solve the problem of petrification.
However, this idea is just Wu Tong's guess and is not convincing.
"Look for any passage nearby.
We came from over there, and the crystals over there are all intact.
Since the crystals here have been mined, they should have come from here."
Wu Tong said, and Pop-up fireball lighting.
Now that it's been determined that there's nothing else, there's no need to hide it.
This time it was Mu Xing who found it.
Behind a pile of crystal debris, Mu Xing found a secret door and even blocked it with a larger crystal, obviously not wanting to be discovered.
However, if you are willing to search carefully, you can still dig it out.
It is not difficult for a careful elf.
"Is this an unexpected gain?"
Wu Tong pushed the crystal for a long time without pushing it away.
In the end, he only moved it away by using flame blast from behind.
After removing the crystal, a tunnel appeared behind it, and there were traces of artificial carving everywhere.
The stalagmites and stone bells had been removed, making it look very flat.
And in terms of height, it was much higher than those people, so it was definitely not done by those people.
"Haha, we found it, let's go."
Opela became more energetic now.
No matter how the process went, her magic finally worked.
Although Opela didn't show it, she was still worried in her heart.
Afraid of losing time.
Now, even if her shadow hadn't found the dark elf, it would still have been of great help.
"Don't be careless this time.
We must find others before they find us.
Do you understand?"
Wu Tong warned.
"Haha, yes, Lord Suzaku."
Opela made a naughty face and took her black cat as her pathfinder
