This night, we all slept soundly, probably because we had a support in our hearts, until the next morning the door was knocked open by the fat man, and we each freshened up and went out of the house.

When we got out of the hut, we found out that David and the headman's sister were also there.

Under a burst of eyes, we also learned the real intention of David's sister, who had already been unable to wait, and this time he was nominally leading us out for a walk, but in fact he was specifically taking us to escape to the mysterious forbidden land.

Naturally, we didn't expect David to be so fast, and what had just been discussed last night would be implemented immediately today, and everyone couldn't be happier about this, and walked with the headman's sister, David, and more than a dozen natives accompanying him.

There were twelve natives armed with bows and arrows who accompanied us, and although they were very burly and strong, they were divided up by the five of us in an instant.

The sea fat man decided to deal with two when the time came, and Jack signaled that he could eat three, and I dealt with one to be on the safe side, and in the end, the remaining six people were covered by Salia and Han Ying.

We all first circled around the indigenous tribe, and on the way, the head sister did not forget to explain to us, in short, the meaning is probably that there are traps everywhere around the whole tribe, suggesting that we should not think about how to escape, especially when looking at the sea fat man, the tone is more firm.

We didn't think in the slightest that the headman's sister was telling the truth, but luckily we didn't set fire to it last time and ran away.

When we all came to the back mountain of the tribe, David's expression began to change a little, and he kept hinting at us with small gestures that it was a mysterious forbidden place.

I looked up a few times. There was indeed a large cave there, and there were two fires on the outside of the cave. The fire on the fire frame is blazing, you don't have to guess to know. It must have been used by the natives to resist the demons in the cave and prevent them from coming out to hurt people.

In the face of such a good opportunity, the five of us also secretly prepared to carry out a surprise attack while the twelve archers were unprepared. The whole atmosphere was a lot tense all of a sudden, and finally under Han Ying's coquettish shout, we pounced on the twelve accompanying people like trapped beasts out of the cage.

I dealt with a relatively easy one, and in the case of a surprise attack, I knocked him out with a few blows.

Seeing the leader's sister screaming in fright, I was about to shut her up, but the figure of David in front of me flashed to stop me, and what I saw in his eyes at this time was full of father's love for his daughter.

It was just a moment when I was stunned. The four of them had already solved their opponents, and in order not to cause trouble to David, we all didn't greet him, and ran directly towards the mysterious forbidden place that was not very far away from us.

Within a few minutes of our escape, the entire indigenous tribe was already in chaos, and the leader rushed over with a group of people, and when they saw the five of us standing at the entrance of the forbidden land, although they were impatient, they still resisted and did not press towards us, probably for fear of offending the demons and gods in the forbidden land.

Seeing that you are about to enter this cave, which can be full of dangers. But we left all the salutes in the tribe, and then look at the natives who are screaming behind us, some of them are angry, some are afraid, and some are reluctant.

I patted the fat man on the shoulder and said lightly, "How is it?" You're about to be separated from your wife, who has been there for a few nights. Is there anything you'd like to say? ”

"Yishou, don't disgust me, it's too late for me to burn high incense." Scolding and scolding, the fat man picked up a matchstick next to him and dodged into the hole. I really wanted to see him in the eyes, but he didn't give me the chance.

Not much to say. After kissing goodbye to this haunted place, each of them picked up a torch and began walking towards the cave that the natives called the forbidden land.

When I stepped into the cave, the first thing I felt was that it was extremely dark and dry, and if we hadn't walked in with torches in our hands, we might have hit the irregular walls of the cave inside.

Jack walked in the front, followed by Salia and Han Ying, and I and the sea fat man walked last, it stands to reason that I and the sea fat man should be replaced with Han Ying, but unfortunately this kind of good thing can only be thought about in the head.

After walking for less than a few minutes, the ghost howl that we had been very conflicted with finally appeared, and its faint transmission froze all of us, and for a while we forgot whether to continue to go deeper.

Jack, who was at the front, said with a trembling corner of his mouth: "Did you hear any sound just now?" Could it be the ghost howl that David said? ”

The fat man walked at the end, and he didn't hear much, let alone him, even I only faintly heard a trace that I didn't know very clearly, I don't know if it was the wind in the cave or other sounds?

So that we might know more exactly what it was, we decided to go some further mile until our ears were full of ghostly howls, and then we stopped our search and stayed where we were.

Salia pursed her lips and said, "Is there really a ghost in this?" ”

"What do you say? What else could this be if it wasn't a ghost howl? The fat man heard it clearly this time, and replied without thinking: "No wonder that David didn't run away with us, there is really a ghost in the relationship, I know at a glance that he is not a good bird, and he deserves to be sucked dry by the old witch." ”

Han Ying finally couldn't listen to it anymore, took down the black cloth strip he had been carrying on his shoulder, held it in his hand and said, "Don't scare yourself, there are no ghosts in here?" As she spoke, she led the way, not afraid of the ghostly howl.

Speaking of the black strip of cloth that Han Ying was holding in his hand, it was the only thing that did not fall, maybe Han Ying regarded it as more important than her own life, and we almost fought with the natives because of the confiscation of it.

With Han Ying taking the lead, Jack, who is an American soldier, was the first to follow, and when Salia also followed quickly, I followed the sea fat man tremblingly, as long as there was something wrong in front of him, he immediately ran back.

Walking and walking, although our ears were filled with terrible ghost howls, but along the way we did not encounter even the slightest evil, which could not help but make us very puzzled, and the sea fat man was even more bold to guess that the torch in our hands played a role.

In this regard, I am more and more convinced of what Han Ying said before, there are no ghosts in it at all. But the terrifying sound is real, and there is only one explanation for these two points, that is, this terrifying sound is naturally formed.

Thinking of this, I couldn't help but say everything in my heart, and when I said that it might be somewhere in the cave or that there was a wind blowing in at the entrance of the cave that caused this echo phenomenon, Salia objected: "Impossible, even if there is a cave nearby, the wind will not have such a big echo when the wind blows in, and this terrible sound is not like the echo of the wind." ”

I see that Salia still knows a lot about this aspect, and what she just said is indeed true, but where did this voice come from?

I couldn't figure it out for a while, and suddenly leaned weakly against the cave wall beside me, but it was okay not to rely on it, and it almost didn't hurt my back to death.

I slammed the torch in my hand to illuminate the cave wall, and a stone wall with no rules and bumps appeared in front of my eyes, and it was only then that I faintly understood.

My behavior naturally aroused the curiosity of Han Ying and a few people, and the fat man asked even more suspiciously: "What's the matter, Yishou, do you have any new discoveries?" ”

I ignored the fat man, and groped for a while on the cave wall in front of me, and when the answer in my heart matched the cave wall, I said aloud: "I think I should know the origin of the ghost howl in the cave." ”

When everyone saw that I had really found the answer here, they hurriedly urged, obviously eager to know what was hidden here? Why is there a howl of integration ghosts?

I touched the uneven wall of the cave and began to explain: "Actually, the terrifying ghost howl in the cave is the sound of the wind blowing in from outside the nearby cave entrance, but when it reaches our ears, it has undergone some internal processing, which leads to a sound similar to that of a ghost. ”

Salia was already puzzled and asked, "Internal processing?" What do you mean? ”

I just smiled at Saria's question, then pointed to the hollow cave wall in front of me, and said again: "Actually, the principle is very simple, these small sunken holes in the stone wall have inadvertently formed a screen-like hollow. When the wind blows in from the outside world produces a sound, if the frequency of the vibration resonates with these small holes, it will produce an amplified version of the sound effect, which is why the ghost howl in our ears is inseparable and still in our ears. ”

"You mean they resonate?" Han Ying, who had been silent, finally spoke up.

I nodded slightly, "Yes, as for why there is a ghostly howl in the sound, you have to go to the mouth of the cave to find out why?" ”

After learning that there were no ghosts in the deep cave, everyone's mental state was obviously much better, and the pace of exploration was faster, after all, there was no fear in their hearts. (To be continued......)
