The two slowed down, perhaps sensing that the atmosphere was too oppressive, Jun Yi tried to whisper, "Senior, could this place be the reason why those purple dragon fish are strange?"

"I don't think it's here, maybe it's in another cave. However, it is still necessary to explore this place first to be sure. Also, now is not the time to be distracted, take a closer look around. ”

has been said so, Junyi is embarrassed to ask anything more. can only learn from Lin Jingfeng and carefully observe the surrounding environment.

As soon as they left the small pool in the center, Junyi had a more intuitive understanding of the size of the cave.

She saw that Lin Jingfeng was looking to the left, so she naturally looked to the right. It's just that, apart from the first sight of the glowing green rock walls, there is really nothing special about it. And it's a closed cave except for the small pond where they came out.

But Junyi also knows that the possibility of natural formation of a cave like this is very low. So now, the senior probably wants to find out the reason for the formation here.

It's just that...... If this place is not a natural formation, then who and for what purpose would they come here to do such a thing?

The cave space is large, as big as two small lakes. But with the walking speed of two people, they will still be able to reach the rock wall in no time.

...........

Looking at the rock wall in front of him, sure enough, as Junyi thought at the beginning, the rock walls here were all glowing with green light. Now, if you look closely, you can see that the reason why the rock wall transmits green light is because the rock particles on the rock wall seem to be mixed with green sand-like substance.

"What kind of rock is this, and why is this happening?" the question naturally blurted out.

Lin Jingfeng didn't answer, but stabbed at the rock wall with the ice spike condensed by the ice ability.

Unexpectedly, with a soft sound of "dang!", the ice spike actually broke!

You must know that the strength of the ice spikes condensed by this ice ability is not something that ordinary rock walls can block. Because the higher the ability level, the stronger the ability attack. For example, the strongest hermit is at the level of destroying the planet.

Although Lin Jingfeng is still a student, he has not yet participated in the assessment of being promoted to a different teacher. But even then, his ability Ice Spike wasn't that easy to break.

So it's clear that the problem isn't with the ice spikes, it's with the rock walls. Maybe that's why the rock walls glow green.

"Senior. Junyi looked at Lin Jingfeng with some concern.

But now he hung his head, not knowing what he was thinking.

"Senior, do you want to ..... Let me try it too?" Junyi asked again.

It's a pity that he still didn't wait for Lin Jingfeng's response. It was as if he was completely cut off, and nothing happened.

Now Junyi is helpless, what can I do? Or ..... Shall I try it myself first?

While thinking about it, Junyi also peeked at Lin Jingfeng several times. But I still haven't seen any change in him.

Eventually, she gritted her teeth and gathered her abilities. The fireball instantly appeared in the palm of his hand, and then he saw Junyi throw it at the rock wall far away from the two of them!

Before Lin Jingfeng came back to his senses, he felt a flash of afterglow, and then a loud "boom" completely pulled him back from his self-thinking.

"What's going on?!" looked up and saw sparks splashing on the opposite rock wall.

"Uh, that. I just asked my seniors. It's just that..... Senior, you've been in a daze and haven't replied to me. However, I don't have much energy in this fireball, so I just want to see if the rock wall can also block the fire energy. "Knowing that this is a bit of a prelude, but since it has already been done, Junyi replied frankly.

The corners of Lin Jingfeng's mouth twitched, he was just thinking, and he didn't notice it for a while, and it became like this.

Fortunately, the rock walls here do not support combustion, and there are no plants in the cave to support combustion, so the humidity is heavy, and soon the sparks formed by the fireballs will gradually extinguish.

Their eyes were fixed on the rock wall that had been attacked by the fireball. After the sparks were all extinguished, he walked briskly over. It seems that although Junyi's move just now is a bit reckless, the result is also very expected.

...........

When he arrived at the rock wall, Lin Jingfeng first attached a layer of ice to his hand, and then touched the rock wall that looked a little darker now.

I wiped it left and right, and soon the black-brown ash was wiped away, and the rock wall revealed inside was still as bright green as before. It's like a fireball just now, but it just adds a layer of ash to the rock wall, and nothing else does anything.

At this moment, the two looked at each other. It is more certain that this rock wall is not simple.

"Senior, what kind of material is this rock wall, it can be blocked by water and fire attacks. If this cave wasn't a natural formation, then the people who dug it out were so good that they could make this kind of rock wall so flat. Junyi saw Lin Jingfeng touching the rock wall with his hands, but he was actually very itchy.

"It is now certain that this place is definitely not something that could have been formed by nature. And ....."

"And what?" Junyi looked at Lin Jingfeng expectantly.

"I'm not sure for sure, but I think the crag is a lot like something I've seen before. Lin Jingfeng's expression became serious. Obviously, the thing he said is very rare, and it is estimated that it is also rare in the outside world.

But he said half like this, which made the curious Junyi very anxious.

I couldn't help but ask again: "Senior, what is it? Do I recognize it?"

Lin Jingfeng turned his head and glanced at Junyi, as if thinking about whether to tell her.

Jun Yi was in a hurry, and hurriedly grabbed his arm: "Senior, you can't be so appetizing, since you've already said half of it, let's finish it all! Otherwise, I won't be able to sleep!"

".........." was said like this, Lin Jingfeng felt that if he didn't say anything again, it was estimated that Junyi would keep holding him and nagging.

However, that thing is very important, and it still needs to be reminded before telling Junyi.

"I can tell you, but you have to promise me that you can't tell anyone about everything here after it's gone. ”

"Why? It can't be..... What are the secrets of this rock wall, right?" It was the first time that Junyi was warned by Lin Jingfeng so seriously, and for a while, her brain was opened, and all kinds of thoughts crossed her mind.

"Well, so to speak. ”

Originally, Junyi was just thinking about it in her head, but now that she has been affirmed by Lin Jingfeng, it is as if she has been struck by lightning, and she was stunned for a few seconds!

After coming back to his senses, he hurriedly said: "Forget it, I still don't want to know." Confidential or something, if I accidentally say something, it will be miserable. ”

Seeing Junyi panic like this, it made Lin Jingfeng, who was originally serious, chuckle lightly.
