"Whew!"

A sharp sound of breaking wind came from inside the cave, echoing in the ears of the dialect.

Fang Yan clutched the grass vine in his hand tightly, his expression slightly nervous, and listened carefully to the sound coming from the cave. After a moment, his face became a little surprised.

The dagger went straight inside the cave, but it didn't seem to have hit any obstacles so far. Not only that, but there were no danger signals coming from inside, except for the sound of the breaking wind, no other sound came out.

"Is there really no one in there?" Fang Yan muttered, he was not too surprised that there was no one or a demon beast inside, after all, if there was someone inside who was a demon beast, he would have been alarmed by his movement just now.

The only thing that surprised him was that the cave seemed to be much larger than he had expected, and after waiting for a few more moments, he summoned his short sword back, and then carefully moved towards the cave.

When he was still a long way from the entrance of the cave, he stopped again, kicked his feet on the cliff, and his whole body swung forward, flashing directly in front of the cave entrance.

It was the moment that flashed in front of the cave entrance, Fang Yan quickly glanced inside, and then he was slightly stunned.

By the light shining through the opening, he had a rough idea of what was going on inside the cave, a straight passage, empty.

The grass vines swung out and soon swung back again. At the moment when he shook past the entrance of the cave, Fang Yan jumped with his strength, and his whole body disappeared from the cliff.

"Whew!"

Before his body was completely stable, Fang Yan's palm quickly raised and threw the short sword in his hand.

The dagger rose into the air inside the cave, spinning around the dialect.

Fang Yan slowly got up, looked around cautiously, and only after making sure that there was no danger around him did he let out a long sigh of relief and carefully observed the cave.

This is not so much a cave as a straight passage, leading straight into the distance, with no end.

The dialect stayed in place for a moment, and then cautiously walked along the passage, the farther it went, the dimmer the light became, and at a distance of tens of feet deep into the passage, the light was more than twice as dim as the position of the cave entrance.

However, even if the light was much dimmer, it was not difficult to see the scene inside the passage.

"Anyone?" The tongue shouted.

The sound ran down the channel, humming.

After a few moments, the passage fell silent and there was no response.

The dialect was not surprised, and continued to move forward unhurriedly. After moving forward for dozens of kilometers, his eyes lit up suddenly, and he looked forward with some solemnity.

Dozens of feet ahead, the light suddenly brightened again.

"Is that the end?" Fang Yan glanced back, and the hole behind him became much smaller in his sight.

"Is anyone there?" He stood there and shouted again.

Still no response.

The dialect continued on, and it wasn't long before a spacious cave appeared before his eyes.

The cave was round, twenty or thirty zhang long, and what surprised him even more was that a passage in front of him led straight into the distance, and standing where he was, he could vaguely see a faint white light seeping in. In addition to this passage, there is also a passage on each side, plus the passage he is in now, it is four.

"Four passages?" Fang Yan's eyes narrowed, and he cautiously walked to the center of the cave, then looked at several holes, and then the corners of his mouth twitched slightly.

These four passages are impressively four entrances.

Although the other three entrances were obscured by grass and vines, he could still make out the faint light at the entrances of the caves, which seemed to be no different from the ones he had just entered.

"What is this place?"

Fang Yan looked around, and there was nothing left in the cave except for a glowing stone above, nothing.

Fang Yan was surprised, and after a moment of hesitation, he walked towards a passage in front of him.

A quarter of an hour later, he appeared at the end of the passage.

"Whew!"

The short sword around him flickered, and the grass and vines at the entrance of the cave broke open, and bright rays of light rushed in.

Fang Yan stood quietly at the entrance of the cave, looking at the quiet forest below with no end in sight, with a complicated expression.

After a long moment, he sighed, turned and walked back, and then walked towards another passage, and after half an hour, he was back in the middle of the cave again, standing silently in place, looking at the huge cave with a puzzled expression.

The four passages in the cave were indeed four entrances, but what he didn't understand was what kind of place this cave was, and there were actually four entrances. What made him wonder even more was that the cave was not only empty, but it didn't even leave a single piece of useful information inside.

However, from some traces in this cave, he can tell that this cave is definitely not a natural formation.

"The person who can build such a cave, his strength is definitely not low." Fang Yan frowned, "It's just, when did he make it, and why did he make four holes?" ”

Just now he looked at all four cave entrances, and found that the cave he was standing in was the highest being within a radius of hundreds of miles, and all around this cliff were lush forests as far as the eye could see, and these forests were all calm and indescribably strange.

Fang Yan reluctantly looked along the edge of the cave to see that in the valley last time, there were many mechanisms in the cave. Maybe there was a secret room inside the cave that he couldn't see.

However, to his disappointment, he searched the cave carefully and found nothing unusual.

"Is there really nothing in this cave?" The dialect couldn't believe it, could it be that the people who dug through this cave were just for rest?

After searching to no avail, Fang Yan sighed helplessly, and then walked towards one of the passages.

Since there was nothing in this cave, there was no point in him staying here. Although it was very safe, he didn't come here to take refuge, he wanted to find a way to get out of here.

Standing at the mouth of the cave, Fang Yan looked up and down, and after hesitating for a moment, continued to climb upwards along the grass.

Since this is the only mountain within a radius of hundreds of miles, people within hundreds of miles should be able to see this location, and if people who have entered this place before want to leave some clues, it is very likely that they will stay on it.
