Chapter 1652

Led by Yun Hao, the group approached the source of the sound.

At this time, the sky above, but suddenly dark clouds, lightning and thunder.

Boom boom!

Raytheon seems to be hiding in the clouds, which is particularly dull. Although the air has been moist to the extreme, it never really means to rain.

Soon they came to the two walls.

Here are the two boulders raised at the bottom of Shentang Bay. A narrow channel is just formed between the two boulders, and the sound of killing comes from the two boulders.

They went to the side of the stone wall and looked inside. The two huge stones are more than ten meters long and more than ten meters high. In fact, the passageway is less than one meter wide and more than ten meters long. Nothing can be hidden inside. Everything is clear at a glance.

But the sound of killing came from the two boulders.

And With the sound of thunder, more and more loud.

Fortunately, Yunhao and his group came here. They are very brave. Even in the face of such strange things, they don't have much fear. If they were ordinary people, they would be scared to death just to hear the sound of golden drums.

"Well, what the hell is going on?" Cloud resolutely looked at the boulder and said, "is it difficult? In this Boulder, there is an entrance to the secret place. At this time, a war is breaking out in the secret place. That's why there is a voice coming out?"

"Sure enough..." Yun Hao suddenly sighed.

The crowd looked at Yunhao, and he asked in vain, "brother Yunhao, do you know anything?"

Yun Hao nodded and said, "do you know, tape recorder?"

"Recorder?" The crowd looked at Yun Hao with an incomprehensible look.

Yun Hao is not surprised by the reaction of the public.

It was in 1898 that Danish people invented tape recorders. In 1907, tape recorders entered the practical stage. During this period, however, China's science and technology have not gone far. Therefore, it is normal for the people of this era not to know what a tape recorder is.

"If you don't know the recorder, you always know the gramophone?" Said Yun Hao.

"Oh, I've heard of that." Yun daoran said, "something that can preserve sound."

"That's right, the principle of the recorder is to use the AC bias method to save the sound..." As soon as Yun Hao said this, he felt that he was playing the piano to a cow.

Chiyang doesn't talk about it at all. The five members of the cloud family can answer their questions about Chinese and arithmetic, but they can't say anything about electromagnetic effects It's better not.

"Generally speaking, the recorder needs electricity and magnet, and then through specific conditions, it can save the sound and play it again." Said Yun Hao.

After simplifying to the extreme, they can finally understand what Yun Hao said.

Then Yun Hao pointed to the two huge stones in front of him and said, "these two stones are magnets, and now There is thunder and lightning in the sky, and there is no rain. The current in the air is higher than usual, so it just meets the requirements of tape recorder, recording or playing. Do you understand what I say? "

Other people are still confused, but Yun daoran is worthy of the appearance of a scholar, immediately clapped his hands and said: "ah, brother Yunhao, I probably know! The recorder you are talking about is something poured out by foreigners, and the two stones here are the things used by God to record sound, right? "

"Yes, yes, yes!" Yun Hao nodded busily and said, "these two stones are the things God used to record sound. The sound of golden drums and the sound of killing and cutting that we hear now are all recorded by God. Now it's just lightning and thunder, so at this time, we broadcast the sound."

With such an explanation, everyone present finally understood.

"But the terrain here is so steep that it is impossible for ordinary people to get close to it. Who will come here to fight?" Cloud Luo ran asks a way.

After a little thought, Yun Hao said, "if I remember correctly, there were a group of rebels here in the Ming Dynasty when Zhu Yuanzhang was still in power. The rebels were near Qingyan mountain and fought against the army sent by Zhu Yuanzhang of the Ming Dynasty. The army sent by Zhu Yuanzhang spent a lot of effort and couldn't completely suppress it. It's because The terrain here is really unpredictable. Maybe that's the sound recorded at that time. "

As soon as he finished, he found that the five people in the cloud family looked at him more eagerly.

"What are you doing looking at me like this?" Said Yun Hao.

"Brother Yun Hao, you Where did you learn that? "

"How do you feel brother Yunhao? You know everything?"

"Sure enough, it's better to travel thousands of miles than to read thousands of books. Brother Yunhao, you've been out for seven years, so you're so knowledgeable?"Cloud Hao heart ha ha a smile, line ten thousand li road? Travel thousands of miles is not as good as Baidu every day!

What don't know, won't search it!?

Of course, this is what people will be able to get after 100 years. Now Whether it's the living environment or the popularity of knowledge, it's too difficult.

"Come on, don't flatter me. We know what's going on with the sound of the golden drums. We'd better go back there and wait. " Said Yun Hao.

The crowd nodded. Yun daoran went to the boulder again and took out a pendant from his pocket. He found that the pendant was really attracted by the boulder and said, "it's really a magnet..."

"Daoran, don't ink there. Come here quickly." "We're all going," he cried in vain

"Right away!" Yun daoran used some strength to pull his metal pendant off the boulder. When he turned to leave, he suddenly found a figure on the other side of the passage formed by the two boulders.

"Wait a minute!" Yun daoran immediately yelled: "don't go, you don't go, I see people, I see people!"

Hearing the voice of Yun daoran, Yun Hao and others quickly returned to the boulder.

"What about people? Where is it? "

Yun daoran pointed to the other side of the passage and said, "it's over there, but I'm sure I didn't read it wrong."

They all looked at each other with a dignified look. Now, no one can judge whether the same people in Shentang Bay are enemies or friends.

Therefore, we must keep enough vigilance before determining the identity.

"Go and see what's going on." Cloud Hao says, plan to bypass huge stone, go to another side to check.

But Yun Yiran and Yun luoran walked in front of Yun Hao. They said with one voice: "Brother Yun Hao, you should follow us. We should open the way in front of us."
