"Tang Shao, this direction is where we walked over in the afternoon, it seems that the legend of Guojia Village is not unreasonable." Ah Hu said.

"Well, keep going!" Tang Dashao frowned.

In fact, at this time, Tang Dashao was already able to detect something......

It's just that he is very strange, in front of himself and the others, there is a blank space, except for plants, mountains and rocks, there is no trace of human figure at all......

Tang Dashao even wanted to probe down to see if there was any movement in the tens of thousands of bones buried below in the place he walked through today......

Of course, he held back......

It's a sight that a normal person would never want to see a second time, especially now at night......

Tens of thousands of skeletons appeared in a person's mind at the same time, and that kind of fear was really not something that anyone could bear......

The crowd continued to move forward, and the sound of fighting grew louder and louder.

If it weren't for the fact that they were in this environment and there was darkness in front of them, they would all be in the cinema, watching the scene of ancient soldiers marching and fighting.

Of course, they can only hear the sound and feel fear, but they can't see the picture!

"Tang Shao, you can't see anything?" Hugo said.

As he spoke, the flashlight in his hand shone in all directions......

Except for the plants and rocks that they had cut down in the afternoon, there was no figure in sight, and all of them could clearly feel that the shouting of killing came from here, and this was the source of the sound!

"What the hell is going on? When I listen to these sounds, how do they feel like they're coming from the mountain wall? Chang Yu frowned.

Mountain walls?

When the ninjas heard this, they all looked at the mountain walls on both sides, but the mountain walls were stone mountains, and what could they see, and they didn't have a perspective ......

Tang Dashao probed the aura into the mountain walls on both sides, and at the same time began to carefully penetrate into the ......

However, after he had probed the distance of hundreds of meters in the mountain wall, although he had gained something else, he still had no idea where the sound came from......

"What the hell is going on? It's weird...... everyone started shaking their heads......

"Do you think it's possible that ghosts exist, and they are indeed fighting, but we can't see it?" Lao Guo Dao.

"So don't you mean that they're all around us?" Zheng Yating's teeth were chattering, and at the same time, a pair of hands hugged Tang Dashao's arm tightly......

"No way, no, if we don't see them, we won't hear them!" Tang Dashao shook his head directly.

He didn't believe that anything could escape the detection of his aura, even the ghost Tang Dashao didn't think it could evade the detection of his aura!

"So how should this phenomenon be explained?" Lao Guo asked.

And at this time, some inexplicable information suddenly appeared in Tang Dashao's mind......

"Heavy rain fell from the sky, and the magnetic field state of the mountains on both sides was abnormal, causing a strange effect, similar to the gramophone invented by humans!"

"Back then, the two armies fought in the torrential rain, and the sound of the fighting was absorbed by the mountain and preserved in a peculiar way."

"Every time it rains, the magnetic field of the mountain is abnormal again, and the sound stored in the mountain is released......"

Nima, I see......

Nature is really amazing, and there is a natural gramophone?

The principle of the human phonograph is not based on this......

"Tang Shao, it's too weird here, let's go back." Huzi Road.

"Hehe, nothing weird, in fact, according to my guess, this phenomenon should be explained by science!" Tang Da Shaodao.

"Explain it scientifically? No kidding, how does science explain the existence of ghosts? Tang Shao, you're not confused...... are you," Hu Ge said in surprise.

Anyway, Hu Ge is also a full-fledged college graduate, if you really want to talk about learning, I am afraid that except for Zheng Yating, there is really no one who can compare to him......

"Hehe, you think too much, there are no ghosts at all!" Tang Dashao shook his head and said.

"No ghosts? So how do you explain the sound now? This kind of shouting and killing is much more real than watching it on TV......" Lao Guo said.

"It's actually very simple, do you know the gramophone? It's a very old thing. Tang Da Shaodao.

"Yes, I still have it at home!" Lao Guo Dao.

"Well, the principle of the phonograph is that the sound vibrations are realized by a undulating track or groove, which fluctuates on the plane of the turntable, and reproduces the pressure changes of the sound waves as accurately as possible."

"As the stylus moves along the groove, the tip vibrates slightly as the groove fluctuates. This vibration is amplified by a membrane transmitted by a mechanical device and emitted into the air. When the turntable is rotated at the same speed as when recording, the sound is accurately restored. ”

"In fact, the mountains on both sides are a natural phonograph!"

"In thousands of years, there were indeed two armies fighting here, and it happened to be raining heavily and thunderstorming at that time, which caused the magnetic field of the surrounding mountains to be abnormal, resulting in the effect of phonograph!"

"Then, every time there is a thunderstorm, when the surrounding magnetic field changes again, the mountain will be like a phonograph turntable, and the sound will be released accurately, and then this is the result that we have now."

"Lao Guo, in the rumors in your village, is it only during thunderstorms that you will hear the so-called immortal heroic spirits fighting?" Tang Dashao asked.

"Rumor has it that only during thunderstorms can the Heroic Spirit recover!"

"However, Tang Shao, how do you know that your guess is right, and there is no basis for your remarks......" Lao Guo said.

"Hehe, if you want to confirm it, it's actually a very simple thing!"

"As long as we record this segment with our mobile phones, and then wait for the next thunderstorm, we will record the sound we hear again, and the two will be compared!"

"If the voices are all the same, there is naturally no so-called immortal spirit, otherwise, even if they fight every day, the shouts will never be exactly the same, right?"

"On the contrary, if the voice has been loud, then there is nothing to say, and my explanation should be able to be agreed!" Tang Da Shaodao.

"Well, that's a good idea, I'll record a video first!" Lao Guo nodded.

"Well, you can try, but if you want to record, you can try it here, we won't accompany you, it's raining here in the middle of the night, just to verify this, it's not a bad brain...... Tang Dashao shook his head.

Now that the cause of the problem has been figured out, Tang Dashao naturally doesn't want to stay here anymore to get drenched in the rain, it's a matter of going back to sleep, and he has to get up tomorrow to hunt for treasures......

Lao Guo was stunned when he heard this, and everyone turned around and left with Tang Dashao......

Look at your phone, listen to the terrifying sounds around you, and finally ......

"Hey, don't go yet, wait for me, wait for me......"

Even though Tang Dashao gave an explanation that there were no ghosts, he also explained the source of the sound in a scientific way, and gave Lao Guo a way to verify it himself......

It's a pity that he still doesn't have the courage to stay here alone......

Not to mention anything else, when he came over in the afternoon, he didn't break the bones of the people below......

Back in the tent, most of everyone's clothes were wet, of course, Tang Ruyan and Zheng Yating were wet except for their shoes and trouser legs, and their upper bodies were still dry.

It's just that when everyone was ready to sleep, Zheng Yating had to sleep in a tent with Tang Dashao, saying that this was the way to feel safe, so Tang Dashao left Chang Yu alone very unrighteously, and then got into the tent of Zheng Yating and Tang Ruyan......

Although the tent they brought was not small, it was more than enough to sleep two people, but it was a little cramped when sleeping three people......

Tang Dashao was lying in the middle, Zheng Yating on the left, Tang Ruyan on the right, and the two women hugged one of their arms and buried it in their chests......

In such a state, how to endure it?

Feeling the softness coming from his arm, Tang Dashao really wanted to freeze time at this moment and never move!

The blessing of Qi people, I have enjoyed it?

"Tang Fei, is what you just said true, is there really no ghost?" Zheng Yating asked.

"This, of course there are ghosts......" Tang Dashao said with a smile.

"Ah, so you just lied to them?" Zheng Yating said.

"Actually, you don't know, at that time, there were a lot of ghosts that surrounded us......" Tang Dashao deliberately whispered.

"Ah......h

Zheng Yating exclaimed, her face was hidden, and her arms holding Tang Dashao became tighter......

"Lie to you, little fool, look at you ...... scared you"

"In this world, whether there are ghosts or not, I don't know, but there are zombies that are real, and I have personally encountered them!"

"However, that sound is really not a ghost, but a mountain, and the specific principle, as I said, is the cause of the magnetic field, which caused a natural phonograph."

"Otherwise, think about it, why is it on a rainy day every time this weird sound appears?"

"If you want to say that ghosts are afraid of the sun, you can come out at night, but at night when it doesn't rain, there is no sound, and it will only appear when it rains, which is enough to explain the problem!" Tang Da Shaodao.

"I see, then you still scare me, tell you to scare me, tell you to scare me......" Zheng Yating's eyes were red, she glared at Tang Dashao, gritted a pair of silver teeth, and then left two rows of tooth marks on Tang Dashao's arms......

Tang Dashao felt the pain in his arm and couldn't help but smile bitterly......

You deserve it, you should suffer it yourself, who makes you cheap, you have to talk nonsense and scare people......

"Hehe, Tingting, since Tang Fei said that there is no ghost, he just lied to you again, do you think we can dare him out of the tent, don't let this bad guy take advantage of us anymore?" Tang Ruyan smiled, and with one hand directly grabbed Tang Dashao's big hand that was making a fool of herself......

Tang Dashao couldn't help but be depressed when he heard this, how could he drive me out if he could hug me left and right......
