Facing the strange Black Stone Mountain, Xiao Chen was surprised in his heart, and let out his emotional doubts:

"What kind of ghost mountain is this? Why are there so many huge caves, it feels like it's not a mountain, but a giant beecomb?"

The Burning Sword sensed it for a while, thought for a moment, and then answered Xiao Chen's question:

"Big brother, this mountain is indeed a little strange, I feel that those caves are full of rich dead air, could it be that there are corpses inside, and this black stone mountain is very likely to be a kind of burial corpse mountain?"

"Burial Mountain?" Xiao Chen couldn't help but be stunned when he heard such a strange mountain name for the first time, and after a moment, he understood the meaning of Burial Mountain, opened his eyes and carefully looked at the huge black stone mountain hundreds of zhang away, and sighed again:

"Xiao Sha, if this is really a mountain of corpses, then this thing is a little terrifying, such a big mountain, so many caves, how many corpses can be buried in it?"

"Big brother, do we need to go into one of the caves and investigate?" the Burning Sword suggested. Pen, fun, and www.biquge.info

"This" Xiao Chen hesitated a little, his eyes glanced at the countless hideous cave entrances of the Black Stone Mountain again, a flash of inspiration flashed in his mind, and he said:

"Xiao Sha, did you say that the strange sound came from the countless caves in the Black Stone Mountain?"

"Big brother, you really dare to think about it, but your guess is very reasonable. "The Burning Sword agreed.

"Woohoo"

At this time, the whine, which had been stopped for a few days, sounded without warning, and the sound was huge, as if it was generated near Xiao Chen, which shocked Xiao Chen's heart, but fortunately, he had been closed to his hearing, otherwise he would have been tricked.

The Burning Sword was not affected by the whine, he immediately judged the source of the sound, which was actually consistent with Xiao Chen's conjecture, so he transmitted the sound to Xiao Chen:

"Big brother, the voice came from the mouth of the cave in the Black Rock Mountain! and not from the mouth of one cave, but from the mouth of the whole cave, no wonder we sounded like an accent. ”

"At such a close distance, this sound is really terrifying, now I feel that my blood is boiling, and I have a splitting headache, it seems that there must be a fierce place in the Black Rock Mountain, I don't know what is inside?"

Xiao Chen stared at the Black Stone Mountain in front of him with great jealousy, feeling that the Black Stone Mountain was not a mountain, but a strange-looking demon, and the demon was whining at him like a mocker.

The Burning Sword felt that Xiao Chen couldn't resist the whine, so he made a serious suggestion: "Big brother, why don't you step back some distance, let me go in and explore, and then come out and tell you what is inside."

"No!"

Before the Burning Sword finished speaking, Xiao Chen decisively rejected the Burning Sword's suggestion: "Xiao Sha, I won't let you enter the dangerous place alone, we are brothers, we want to advance and retreat together and live and die together." ”

"Besides, if we can't crack the secrets of the Cloud Forest, then none of us can leave the Cloud Forest, so we must stay together at all times and deal with any dangerous crisis with the strongest group. ”

"Big brother, I know, I just suggested it, just talk about it, quack. ”

The Burning Sword was a little embarrassed by Xiao Chen's words, so he changed the topic and said, "Big brother, should we enter or not enter Black Stone Mountain now?"

"Wait a minute, let's see if this ghost sound will stop, I can't resist this ghost sound, presumably the sound inside the stone mountain will be louder, if I venture in, I am very likely to be hit. Xiao Chen replied solemnly.

"Okay, it's up to the eldest brother, let's step back a little distance and wait for this ghost sound to stop. "The Burning Sword agrees, after all, safety comes first.

So, Xiao Chen cautiously stepped back and drove away, and it was not until he retreated about a hundred zhang that he stopped, at this time he felt a little better, and was within the range that could withstand the impact of the whine.

I thought that this whining would last for many days, but after half a day, the whining stopped, and there was no movement for a whole hour.

After waiting for another half an hour, to make sure that there was no problem, Xiao Chen began to walk towards the Black Stone Mountain, the speed was faster than before, obviously he was worried about the whining again, so he planned to hurry up.

The distance of hundreds of zhang was finished in less than a while, and at this time Xiao Chen had arrived at the foot of the mountain and began to climb up carefully.

The Black Rock Mountain is a little steep, but this steepness is nothing to Xiao Chen, his strength is strong, his body is strong, his body is agile, plus he can fly, it is extremely easy to climb the mountain.

The only thing that is not easy is Xiao Chen's mood, because Xiao Chen may be walking on the road to death, how can his mood be relaxed?

Xiao Chen holds a sword in his right hand, his left hand is in the shape of a claw, the spiritual power of his whole body is circulating, his muscle strength is ready to go, he sees all directions, listens to all directions, and can deal with any unexpected things at any time, especially the existence of danger.

The first cave was less than five zhang away from Xiao Chen, Xiao Chen planned to choose the nearest cave to enter and explore, once he found an invincible human beast, then he would fly out as soon as possible.

"It's so full of dead air, and there is a kind of fishy and cold feeling. Getting closer and closer to the cave, Xiao Chen felt the special aura permeating the cave, and he couldn't help frowning.

"Big brother, there must be a lot of dead bodies in the cave, and there may also be demon beasts such as snakes and rats. The Burning Sword asserted that what he said was true.

"Well, let's always be ready to fight. Xiao Chen nodded solemnly, and the strength of his right hand holding the sword was a little stronger.

Since he decided to go into the cave to explore, Xiao Chen will not easily change his mind and get a tiger if he doesn't enter the tiger's den?

After a while, Xiao Chen finally arrived at the mouth of the nearest cave, and after a visual inspection, he felt that the mouth of the cave was like a circle and a square, with ancient traces of artificial mining, and the entrance of the cave was very large, which could accommodate several people at the same time.

Standing at the entrance of the cave, a fishy smell rushed towards him, choking Xiao Chen's brows wrinkled even deeper, but fortunately, he had super endurance, and he might vomit directly if someone else changed.

Looking into the cave, I found that the passage of the cave was very long, and the depth of the cave passage was pitch black, and it was estimated that it led directly to the center of the mountain.

"Enter!"

Xiao Chen stayed at the entrance of the cave for too long, his body jumped, and he entered the cave passage, he didn't dare to go fast, but walked very slowly, his spirit was highly concentrated, and his perception was fully released, and he didn't dare to take it lightly.

"Da, da, da" Although Xiao Chen's footsteps were very light, they were still extremely clear in the dead cave passage, and the sound transmitted to the cave walls and the depths of the passage caused some echoes, making the originally weird atmosphere even more terrifying.

When he walked about thirty zhang away, a strange sound similar to hissing came out from the depths of the cave, the sound was weak and inaudible, but it was still captured by Xiao Chen.

"Snakes, and there are quite a few of them, is this battered black stone mountain a huge snake cave?"

Xiao Chen had a bold guess in his heart, he was very disgusted with snakes, so he underestimated: "I hope that there are no demon snakes in this stone mountain that are in the Semi-Holy Beast Realm or even the Heavenly God Realm. ”

Xiao Chen didn't close his hearing, if he entered the cave and closed his hearing, then he would be easily attacked by potential enemies or enemy beasts, and that would be a big loss.

You can't have it both ways.

For that kind of terrifying whine defense, in addition to sealing his hearing, Xiao Chen didn't think of any other good way for the time being, in order to hear the subtle sounds in the cave, he had to lift the closure of his hearing.

"Big brother, you don't have to worry about dealing with snakes and other yin things at all, have you forgotten that your spiritual power has some power of heavenly thunder, snakes are the most afraid of the power of thunder and lightning, not to mention the power of heavenly thunder that is higher than the power of ordinary thunder and lightning. ”

The Burning Sword heard Xiao Chen's muttering, and said disapprerovitously, not taking the snake demon beast in his eyes at all.

"The power of the thunder, I hope it's useful. Xiao Chen's eyes lit up, his somewhat fluctuating mind calmed down again, and he continued to walk inside the cave passage, but his speed slowed down slightly.

Continuing to go deeper into the cave, the light in the passage was almost gone, and it was pitch black.

However, Xiao Chen's eyes were like torches, and he could clearly see everything nearby, and he found that the cave passage was almost at the end, maybe when he arrived at the mouth of the inner passage, he would be able to know what was in the mountain?
