I don't know if I stayed in this cave for a long time to get used to the dark light, Fang Yan suddenly felt that it didn't seem so dark in front of him, and the scene within half a zhang could vaguely see a rough outline.

"I don't know how big this place is, or who made it." Fang Yan sighed bitterly, and secretly said that he had fallen into this cave, and he didn't know whether it was a blessing or a curse.

He believed that this cave was certainly not dug by someone who had nothing to do, and since it existed here, it should have its purpose. It's just that what exactly it does, but the dialect is unknown.

He didn't even know if the cave had been dug by the great supernatural people of antiquity, or if it had been dug by the people who had entered the valley later to take refuge.

If this cave had been dug by some great supernatural people in ancient times, there might have been some treasures in it, and there might even be an exit to the outside world. But if this cave was dug by the people who entered the valley later to take refuge, then there may not be a second exit from this cave, which means that he may be trapped here and die.

Such a pitch-black environment reminded him of the scene when he was in the valley where he got the formation, when he was in that valley, in that thick white mist, the scene seemed to be not much different from now, his vision was blurred, and he couldn't see anything outside his body.

The difference is that what was a white fog is now pitch black. Moreover, his current environment is even worse than the white fog at the beginning, and the visibility is not even half a zhang, and he can only barely see his five fingers clearly.

"Woo......"

Suddenly, a low sound sounded in the cave.

The deep voice sounded in this pitch-black environment without warning, making people feel creepy in their ears.

Fang Yan's footsteps paused, and his face became a little difficult to look at, as if he didn't expect to run into trouble so soon.

If this demon beast's strength is stronger than him, in such a dead end, he may not be able to escape death. Because, there is no way for him to escape.

Fang Yan held his breath, collected all the breath on his body, and looked around nervously. He didn't even know which direction the sound came from.

The strange thing is that while Fang Yan reined in his breath, the demon beast that made this sound didn't make any more movement for some reason, making Fang Yan even wonder if it was his own auditory hallucination just now.

This demon beast should have also inadvertently fallen and trapped in this cave, since it was trapped here, then, its strength should not be too strong, it should not have reached the level of soul return.

Fang Yan comforted himself in this way in his heart, and looked around cautiously.

However, what could he see in the darkness all around?

"Could it be...... Did this demon beast perceive that its strength was lower than mine, so he didn't dare to show up? "The dialect is bitter and happy, but he does not dare to relax in the slightest.

If this demon beast really stopped making a movement for this reason, then it could have been completely silent just now. If it hadn't made that low chirp, he probably wouldn't have discovered its existence.

Fang Yan waited for a moment, and with a sudden wave of his palm, a Yuan Qi attack came out of his hand and fell to the ground in front of him.

After unleashing this attack, he moved quickly and retreated half a foot away.

"Bang!"

The Yuan Qi attack landed on the ground, and there was a soft sound, and the sound echoed in this dark cave, slightly dull.

There was a sound, but there was still silence all around, and there was no sound. The monster that made the sound earlier seemed to have left the cave.

The corners of Fang Yan's mouth were filled with bitterness, if this demon beast had been hiding like this and not showing up, he really wouldn't dare to move around at will.

After waiting for a few more moments to no avail, his brow furrowed unconsciously.

He didn't want to be trapped here like this, but he didn't dare to act rashly until he didn't know the strength of this demon beast. After thinking for a moment, he nodded slightly, and the palm of his hand holding the short sword slowly loosened.

"Whoosh!"

The dagger burst straight up, swirling around him with a faint glow.

Fang Yan breathed a sigh of relief and walked forward cautiously step by step.

It was strange to him that he had gone five or six feet like this, and had not encountered any danger. The monster that made the noise before seemed to have suddenly disappeared.

"Whew!"

But at this moment, a rapid sound of breaking wind suddenly sounded in his ears, and immediately after, he saw a very vague black shadow rushing from the front.

Fang Yan was taken aback, and his palms were raised.

"Jingle bell!"

A melodious bell rings in this dark space.

"Whoosh!"

At the same time as the bell rang, three or four fist shadows also rolled and galloped forward.

"Whew!"

The vague black shadow in front of him suddenly let out a somewhat terrifying roar, and with the faint light emitted by the fist shadow, Fang Yan vaguely saw a demon beast with a bloody mouth leaping in front of him, rushing down from the high sky.

The sound of the bell doesn't seem to do much harm to it.

Fang Yan gasped violently, his palm suddenly stretched out, took the short sword around him in his hand, and swung it three times into the air without hesitation.

"Boom!"

The majestic vitality flickered out from the tip of the sword, and it collided with the oncoming demon beast fiercely.

"Boom, boom!"

After three loud bangs, an unexpected scene appeared.

The monster vanished in midair.

Fang Yan swallowed with difficulty, and looked at the air inexplicably.

With the faint light that flickered from the explosion of a few Yuan Qi, he clearly saw that after the demon beast was violently attacked by the three human swords in one, its entire body was actually dispersed in mid-air like a light smoke.

What kind of monster is this?

Such a thought unconsciously flashed in Fang Yan's mind.

Although he couldn't see the strength of this demon beast just now, he could also sense the breath coming from the other party's body, and the strength of this demon beast was not lower than him, and it was impossible for him to die like this.

He suddenly remembered the scene in the white fog of another valley, and in that white fog, he remembered that he had encountered such a situation before. After being attacked by him, a demon beast strangely turned into a puff of light smoke and dissipated.

"Could it be that I encountered that weird monster again?" Fang Yan muttered, his expression extremely solemn.

The situation that he didn't want to encounter still appeared, the strength of this demon beast was much stronger than him, and if he was not careful, he might have to stay in this cave forever.
