The shouting and killing sound in the frightened horse gully became louder and louder, deafening, and I felt that this time the scale of the Yin soldiers' borrowing was even larger than the previous one.

With the wind through the hall in this ravine, these ghosts and ghosts are rushing forward in the wind, so imposing, terrifying, although you can't see anything, you can feel a strong sense of oppression in the air.

Chen Jieyang, Guo Na, Shen Wei, and Xin Ling retreated to the side of the road, waiting in horror for the Yin soldiers to pass. Yu Fan didn't think so, stood in the middle of the road, closed his eyes, and opened his hands, as if he was enjoying himself.

Chen Jiaoyang shouted: "Old Yu! What are you doing? Are you crazy? Come back soon. ”

Yu Fan closed his eyes slightly and said, "I'm feeling the battlefield hundreds of years ago, what a rare opportunity this is." ”

The second monk Chen Xiangyang was puzzled, he felt that Yu Fan was not stupid, and shouted again: "Wake up, old Yu, don't wave." ”

Yu Fan: "When you are immersed in the scene, you will feel that the real battlefield is far more intense than the movie. ”

Shen Wei didn't dare to raise his head, lowered his head and closed his eyes tightly, silently reciting in his heart Buddha bless, God bless, as long as whoever blesses me now is my father.

The "Yin Soldiers" came and went fast this time, and in about a minute, the shouting and killing disappeared. The ravine was quiet again.

Xinling looked at Shen Wei, who was shy, with her head down, and said with a smile: "Brother Mao, it's okay, they're gone." ”

Only then did Shen Wei dare to open his eyes quietly, he realized that his performance was really a bit ungentlemanly, so he pretended to be calm and slowly raised his head, looked up to the sky and laughed: "Hahaha, the eldest husband is like this, he can bend and stretch." Do you think I'm scared? No, everything is in my control. After saying that, he began to make a pretending expression again.

Boys will always be extra excited and love to perform in front of the girl they have a crush on, and they will also become "a lot more witty", even if they accidentally slip and lie on the ground, they must deliberately do two push-ups in front of the goddess to show that they are exercising. It's all dopamine and hormones.

Chen Jieyang said to Shen Wei with an expression of understanding and long live: "I understand the truth, but why are your pants yellow again?" ”

Xinling hurriedly mended the knife: "Scared out of?!" ”

Shen Wei hurriedly covered his buttocks, embarrassed and unable to speak.

The gentle Guo Na helped Shen Wei relieve the siege: "The yellow one is just the soil on the ground just now." ”

Chen Jiaoyang smiled evilly and pulled Shen Wei's hand: "Really?" How do I smell the stench? ”

The atmosphere is cheerful again, and I have to admire that everyone's mentality is still very good, and they have not been robbed of their minds by the "Yin Soldiers".

Yu Fan also smiled and said to everyone: "We'll talk about or not, but I know what is going on with the Yin Soldier's borrowing of the Dao." ”

Guo Na hurriedly asked: "That's right, Brother Yu said before the Yin soldiers came just now that you know the reason, what is going on?" Aren't these sounds the sounds of ancient battlefields? ”

Yu Fan pushed his glasses and said, "I think that the sound is indeed the sound of ancient wars, such as a fake. ”

When Shen Wei heard this, his hair stood up, and he trembled and said, "So it's true?" Oh my God! There's a ghost.,It's really unclean now.。 ”

Yu Fan calmly explained: "Don't worry, the voice is real, but the ghost is fake. ”

This confuses everyone, if the ghost is fake, then how can the voice be real?

Chen Frameyang asked, "Real voice?" There is only one possibility, is it that someone traveled back to ancient times and recorded the sound with a tape recorder, and then traveled back to play it? ”

Yu Fan laughed and said, "Maybe there is another possibility." ”

Everyone pricked up their ears and waited for Yu Fan to reveal the answer.

"Perhaps, this whole shocking horse is an out-and-out natural tape recorder!" Yu Fan said solemnly.

Yes?! Everyone was very surprised and surprised by this answer.

Yu Fan explained unhurriedly: "I just carefully observed that the geochemical components in this shocking horse gully are mainly silica and magnetite. Silica has very good conductivity, and people often make it into various electronic components and install them in tape recorders. Magnetite, on the other hand, refers to the ore of the oxide mineral magnetite. It belongs to the equiaxed crystal system. The crystals are octahedral and dodecahedral. The crystal plane has streaks. Most of them are aggregates of granular blocks. Iron-black, or dull blue-indigo. Streaks black, semi-metallic luster. Opaque. The fracture is uneven. Hardness 5.5~6.5. The density is 5.16~5.18gcm3. It has strong magnetic properties. Brittle. Odorless, tasteless. It is often found in magmatic rocks and metamorphic rocks. It is also often found in the sands of the seashore. It is distributed in Shandong, Hebei, Henan, Liaoning, Heilongjiang, Inner Mongolia, Hubei, Yunnan, Guangdong, Sichuan, Shanxi, Jiangsu, and Anhui. ”

Yu Fan paused and continued: "When these two substances are together, they will have the function of recording under certain circumstances. And the Surprise Horse Gully happens to have such conditions. ”

Chen Jieyang asked, "What conditions?" ”

Yu Fan: "Electric field and magnetic field. The geographical location of Meridian Village and Shocking Horse Gully is very unique, and it is already in a huge magnetic field, which is why our mobile phones have no signal and the compass fails. ”

Shen Wei suddenly realized: "I just said that the Internet speed in our village is so rubbish, it turns out that it is due to the magnetic field." ”

Xin Ling asked again: "That's not right, if you say that the Shocking Horse is a tape recorder, then there are so many sounds here for thousands of years, why is it only the sound of war?" And what about playing only the sound of war? ”

Yu Fan: "That's a good question. The reason for this is lightning! Although it is a natural tape recorder, this tape recorder is only ready for tape, but it is not plugged in. The phenomenon of Yin soldiers borrowing the way in the panic is not always there, and it will only appear when lightning strikes. This is because the electrical energy from the lightning charged the recorder and the recorder began to function. ”

Guo Na understood it at one point and said, "I understand." A hundred years ago, two armies fought here, and they happened to encounter a thunderstorm, so the fierce battle was completely recorded by this tape recorder. The sound is firmly embedded in the tape, and every time there is a lightning flash, the tape is activated by electrical energy, which is equivalent to pressing the play button, so we can hear the sound of the ancient battlefield. ”

Shen Wei: "Although I don't quite understand, I think what you said makes a lot of sense." ”

Yu Fan raised his head again, looked at the sky, and said slowly: "Nature is really magical, and unconsciously, we have become witnesses of history. I wonder if there will be anyone who will witness our history one day in the future? ”
