The store is full of passers-by

Rumble, boom!

Thunder God seemed to be hiding in the clouds, looking extremely dull. Although the air was extremely humid, there was no real intention of rain.

After a while, they came to two walls.

Here are two boulders protruding from the bottom of Shentang Bay. A narrow passage just formed between the boulders, and the sound of killing came from these two boulders.

A group of people walked to the side of the stone wall and looked inside.The two boulders are more than ten meters long and ten meters high. The passage formed by this is actually less than one meter wide and more than ten meters long. There is nothing hidden inside, and everything is clear at a glance. .

But the sound of killing came from within the two boulders.

And... accompanied by the sound of thunder, it became louder and louder.

Fortunately, it was Yun Hao and his group who came here. They are brave people with high skills. Even in the face of such weird things, they don't have much fear. If they were ordinary people, just hearing the sound of the golden drum The voice is probably about to be frightened.

"Hey, what's going on here!" Yun resolutely looked at the boulder, and said, "Could it be that there is an entrance to a secret realm inside this boulder, and at this moment, a great battle is breaking out in the secret realm, so there is a voice coming from the boulder?" come out?"

"As expected..." Yun Hao suddenly sighed.

Everyone looked at Yunhao, and Yun asked in vain, "Brother Yunhao, do you know anything?"

Yun Hao nodded and said, "You know, the tape recorder?"

"Recorder?" Everyone looked at Yunhao with puzzled expressions.

Yun Hao was not surprised by everyone's reaction.

In [-], the Danish talents came out with the tape recorder, and in [-], the tape recorder entered the practical stage.During this period, China's technology has basically not advanced much, so it is normal for Chinese people in this era not to know what a tape recorder is.

"I don't know about tape recorders, but I know about gramophones, right?" Yun Hao said.

"Oh, I've heard of this." Yun Daoran said, "It's something that can preserve the sound."

"That's right, the principle of the tape recorder is to use the AC bias magnetic method to preserve the sound..." Yun Hao just said something, and felt that he was playing the piano with a cow.

Let’s not talk about Chi Yang, the five members of Yun’s family, if they are asked Chinese and arithmetic, they will definitely be able to answer them, but when they talk about electromagnetic effects... let’s avoid it.

"Generally speaking, the tape recorder needs electricity and a magnet, and through certain conditions, the sound can be preserved and played back again." Yun Hao said.

After simplifying to the extreme, they were finally able to roughly understand what Yun Hao said.

Then, Yun Hao pointed to the two huge rocks in front of him and said: "These two rocks are magnets, and now...there is thunder and lightning in the sky, and there is no rain, so the current in the air is higher than usual. Therefore, it just fully meets the conditions of a tape recorder, recording or playback, do you understand me when I say that?"

The others were still dumbfounded, but Yun Dao was worthy of his appearance as a scholar. He immediately clapped his hands and said, "Ah, brother Yunhao, I probably understand! The tape recorder you mentioned was made by a foreigner." Things, and the two stones here are what God used to record sounds, right!"

"Yes, yes, yes!!!" Yun Hao nodded hurriedly and said, "These two stones are what God used to record sounds. The sounds of golden drums and killing that we hear now are all from God. It was recorded, and now there is lightning and thunder, so at this time, the sound is played out."

With such an explanation, everyone present finally understood.

"However, the terrain here is so steep that it is impossible for ordinary people to get close to it. Who would come here to fight?" Yun Luoran asked.

After thinking for a while, Yun Hao said: "If I remember correctly, during the Ming Dynasty, when Zhu Yuanzhang was in power, there was a group of rebels here, and the rebels were near Qingyan Mountain. Fighting against the army sent by Zhu Yuanzhang of the Ming Dynasty, the army sent by Zhu Yuanzhang spent a lot of effort, and there was no way to completely suppress it, because the terrain here is really unpredictable. Perhaps it was at that time, the recorded voice Bar."

As soon as he finished speaking, he noticed that the five members of the Yun family looked at him with more eager eyes.

"What are you doing looking at me like that?" Yun Hao said.

"Brother Yunhao, you... where did you learn all this?"

"How do you feel, Brother Yunhao, that you know everything?"

"Sure enough, traveling thousands of miles is worse than reading thousands of books. Brother Yunhao, you have been traveling for seven years, so you are so knowledgeable?"

Yunhao chuckled in his heart, traveling thousands of miles?Traveling thousands of miles is not as good as going to Baidu every day!

If you don't know anything, don't you go to search! ?

Of course, this is the kind of treatment that can only be enjoyed by people 100 years later. Nowadays... Whether it is the living environment or the popularity of knowledge, it is too difficult.

"Okay, why don't you flatter me. We also know what's going on with the sound of these golden drums beating together, so let's go back and wait there." Yun Hao said.

Everyone nodded, Yun Daoran walked to the boulder again, took out a pendant from his pocket, found that the pendant would really be attracted by the boulder, and said, "It's really a magnet..."

"Daoran, don't smudge over there, come here quickly." Yun vainly shouted: "We are leaving."

"Come right away!" Yun Daoran used some strength to tear his metal pendant off the boulder. When he turned around to leave, he suddenly found that on the other side of the passage formed by the two boulders, there was a The figure flashed by.

"Wait a minute!!!" Yun Daoran yelled immediately: "Don't go, don't go, I see someone, I see someone!!"

Hearing Yun Daoran's voice, Yun Hao and others quickly returned to Jushi's side.

"Where are people? Where are they?"

Yun Daoran pointed to the other side of the passage, and said, "Over there, it passed by in a flash, but I can be sure that I saw it right."

Everyone looked at each other with solemn expressions.Now, no one has the way to judge whether the people who also appeared in Shentang Bay are enemies or friends.

Therefore, sufficient vigilance must be maintained before determining the identity.

"Go and see the situation." Yun Hao said, planning to go around the boulder and check on the other side.

But Yun Yiran and Yun Luoran walked in front of Yunhao, and they said in unison: "Brother Yunhao, follow us, we will open the way ahead."

The first thousand and 650 chapter three: going down to the Tiankeng

Yun Hao could vaguely feel that these five members of the Yun family must have been told to protect him and so on.

After all... Yunhao's current "identity" is the younger brother of the head of the Yun family, and he is very likely to be the successor of the next head of the family.As disciples of the Yun family, Yun Daoran and the others would not allow Yun Hao to get hurt under his protection.

Although the sense of security of being protected by others is very good, Yunhao feels that he doesn't need them to worry about him so much. In terms of strength, the five of them, no matter who they are, are not Yunhao's opponents alone , unless two or more people team up, it is possible to draw with him,

But now, it seemed that he would not encounter any danger, so Yun Hao refused their protection, and surrounded by the crowd, he bypassed the boulder.

When they got to the other side of the boulder, they found that there was no one there either.

"Where are people?" Yun asked in vain.

Yun Daoran looked around and said, "No, I just saw someone. He was standing on the other side of the passage, showing half of his body, looking straight at me. When I looked up, he had disappeared. .”

"Didn't you see some hallucinations?" Yun said in vain, "Since God can leave voices, maybe he can also leave pictures, allowing you to see things thousands and hundreds of years ago."

After finishing speaking, Yun Wuran felt as if he had discovered something extraordinary, looked at Yun Hao excitedly and said, "Brother Yun Hao, tell me...can you really keep the picture?"

"Yes, but it's more complicated. After a few decades, it will definitely be possible." Yun Hao said: "But now, it's not the time to discuss these things."

"Brother Yunhao, I just saw someone passing by." Yun Daoran said.

Yun Hao walked to the side of the stone wall passage, squatted down suddenly, and said, "I believe you didn't see hallucinations, but are you sure that what you saw must be human?"
