The triangular demon beast looked at the giant wolf that turned into a cloud of green smoke and left, and after blinking its eyes, it didn't catch up, and slowly walked towards the cave. Looking at his appearance, it is obvious that he is more interested in dialect, or he senses the faint breath on dialect and wants to feast him.

Seeing the triangular demon beast cautiously approaching, Fang Yan's heart suddenly became a little complicated. It seems to be a little afraid of this cave, too.

Looking at his appearance, he should be like a giant wolf, not daring to enter the passage behind him. That way, he at least didn't have to worry about it catching up. However, if even it does not dare to enter, then this passage is really a little terrifying.

Fang Yan quickly glanced back, then looked back at the triangular demon beast that was getting closer and closer, and after taking a deep breath, he turned around and walked directly towards the passage behind him.

"Roar!"

At the moment when he turned around, the triangular demon beast behind him suddenly roared, and the speed under his feet suddenly accelerated, rushing towards Fang Yan.

Fang Yan's heart jumped violently, he was still a little hesitant, he couldn't care about anything anymore, he ran directly, and rushed three or four feet deep into the passage in the blink of an eye.

After entering the passage, he still didn't dare to stay, and quickly ran inside. If he was caught by this triangular demon beast now, he would definitely not be able to escape and die.

Running on him, he glanced back quickly, and then his footsteps stopped for a moment. Because he found that the triangular demon beast was standing in the cave and did not chase after him.

Fang Yan secretly breathed a sigh of relief, quickly looked at the place, and only relaxed after noticing any danger, staring vigilantly at the triangular demon beast that kept roaring at him.

At this time, the triangular demon beast seemed to be standing at the entrance of this passage, but for some reason, it did not dare to step into this passage, as if there was some magic obstacle in this passage.

Seeing that the triangular demon beast didn't dare to step into the passage, Fang Yan frowned unconsciously. He quickly looked around the spot, but still didn't find any danger. There was nothing but some solid rock around.

If I had to say anything else, it would be just a few glowing stones embedded in the rocks.

Seeing that the triangular demon beast did not dare to enter, Fang Yan did not plan to continue to go deeper after hesitating for a moment, after all, this cave was too weird. Unexpectedly, the two demon beasts with the strength of the mid-stage of the Soul Condensation Realm did not dare to enter.

Fang Yan stood still, looking around boredly, and after looking into the depths of the passage, a look of surprise appeared in his eyes. Because he suddenly found that just a dozen feet in front of him, the vertical passage actually began to turn.

Fang Yan couldn't help but be stunned for a moment, staring at the passage more than ten zhang away in front of him for a long time, and after not finding any obvious traps, a look of hesitation flashed in his eyes.

Half an hour later, he couldn't help but lift his feet and cautiously walked inside. With every step, he had to breathe a sigh of relief. Its nervous appearance was not much different from the state of the crimson demon beast he had encountered when he first entered this valley.

Under such careful walking, he walked for a quarter of an hour at a distance of more than ten zhang. What made him breathe a sigh of relief was that there were no accidents on the road for more than ten zhang, let alone any danger at all.

Fang Yan cautiously came to the bend of the passage and looked towards the end of the passage. At this look, his pupils suddenly dilated, and he gasped violently, his eyes full of shock.

Twenty or thirty feet away from the passage, a large cave suddenly opened up in front of his eyes. Although Fang Yan could only see some of the faces of the cave where he was standing at this time, he could vaguely guess that the mountain he had seen outside before had been hollowed out.

What surprised him even more was that this huge cave was still illuminated by something, even several times brighter than the passage he was in now.

"What the hell is this place?" Fang Yan looked horrified, he didn't believe that a cave like this was naturally formed. It must have been man-made.

"Could it be...... Is there anyone else in here? Thinking of this possibility, Fang Yan's heart was slightly startled, and after his lips moved, he still didn't dare to shout anything.

He was afraid that the slightest movement would lead to mortal danger.

Looking at the brightly lit cave in front of him, his eyes rolled rapidly. Because he suddenly thought of the cave he accidentally entered when he was in Heavenly Bow City, the cave that gave him the spirit of vitality.

If you think about it, the situation at this time is really similar to what it was at the beginning. At first, he was seriously injured, but at this time he collapsed all over his body. And the results are strikingly similar, they are all unable to use the vitality.

It's just, I don't know what he's going to get inside this cave?

Fang Yan knew that it was not difficult to hollow out this mountain, and some people with great magical powers could make the entire mountain disappear with a wave of their hand, let alone such a simple matter of hollowing out this mountain.

However, it is a little difficult to hollow out this mountain before it collapses, and I don't know how many years this mountain has existed. He didn't believe that the people who hollowed out the mountain were just digging casually.

If he didn't guess wrong, the person who dug out this cave should have something to do with the ancient formation that Ye Yuanhe said in his mouth.

Thinking of this, Fang Yan's eyes became a little hot. There is a lot of anticipation for this cave.

If he hadn't been unable to use his vitality now, I'm afraid he would have rushed in a long time ago, where would he hesitate here for so long.

"Anyone?" After struggling for a moment, Fang Yan still shouted into the passage with all his strength. Because he didn't see the corpses of some demon beasts in this passage.

From this, he could guess that there should be no danger hidden in this passage, otherwise, this passage should have been covered with the bones of demon beasts a long time ago, where could it be so clean.

After all, monsters are different from humans, and they don't think like him after straying into this cave, and they will definitely make a lot of noise. He didn't believe that no monsters had entered this passage.

If there was no demon beast entering, then the triangular demon beast outside would not be so jealous of this passage. What's more, he knew that the cyan wolf had entered the cave.

It is not known what they encountered in this cave that made them so afraid of this cave, but at least, they all seemed to be alive and well. After figuring this out, the dialect became a little impatient.

After shouting that, he waited quietly in place. Not to his surprise, his cries were not answered.
