Five people were rescued, but only two of them had vital signs.

The mortality rate is surprisingly high.

He Yan, Gao Sheng and Kang Qi looked at each other, and all the regrets were revealed in his eyes.

A good life is because the criminals are crazily bombing the tunnel, causing the living life to pass away.

Thinking of this, the three of them were filled with anger.

"Save people!"

"Anyway, the gangster has been caught, and he will pay the price for his actions."

"Too."

"Save it."

The three of them talked to each other, but the work in their hands did not stop.

...

"Help!"

"Who will save us!"

A life-saving sound came from the front of the tunnel.

That's right, the voice is Fang Zijing and his subordinate Zhao Yongbin.

The sound of excavation and shouting in the tunnel reached the ears of the two of them.

The two men who were resting in the corner suddenly opened their eyes, knowing that rescuers had entered the tunnel.

So, he started to shout.

"Boss, can they hear it?"

"We're all hoarse?"

Zhao Yongbin was a little discouraged and asked Fang Zijing in a puzzled tone.

"shit!"

"Of course we can hear them, we can hear their shouts, and they can definitely hear our calls."

"Oh... why haven't they responded to us yet?"

"You ask me, who will I ask!"

Fang Zijing was a little annoyed, "Don't ask so much, keep shouting."

“Yes!”

Seeing that the boss got angry, Zhao Yongbin shrank his neck and nodded in fear and said yes.

"Help!"

"Can anyone hear it?"

"Get the stone to make a move."

Fang Zijing picked up the stone and found a relatively safe location, and smashed it hard against the wall.

"boom……"

"Dong..."

Seeing this, Zhao Yongbin followed suit and immediately picked up a stone and smashed it.

"Dong...Dong..."

The sound of stones colliding echoed in the tunnel and spread far and far away.

The propagation of sound needs to pass through the medium. The greater the density of the medium, the faster the propagation speed and the greatest density of the solid, so it propagates faster in solids than in liquids and gases.

Fang Zijing took advantage of this and used a stone to hit the stone to produce echoes so that those who were rescued outside could hear the sound.

"Dong...buzz..."

"Dong...buzz..."

The stone hit the stone rhythmically, and the sound was also transmitted at once.

"Boss, can this work?"

Zhao Yongbin wanted to ask, but Fang Zi turned his eyes off and shut up and stopped asking.

Outside.

Kang Qi happened to be close to the stone wall, and wanted to hear where there was a sound.

When I got closer, I really discovered something.

He heard a rhythmic knock, which came over regularly.

“There is a discovery.”

"Gao Sheng, come and listen."

When Gao Sheng heard Kang Qi call him, he immediately came over to listen to the stone wall.

"Have you heard it?"

"Well, the regular knocking sound must be a distress signal from someone."

"Yes, I think so too."

Kang Qi nodded and then asked the Northwest Army to quickly search from the direction of the sound.

The Northwest Army searched and cleared out obstructing stones.

Behind them, the workers, under the command of the deputy captain, quickly dig into the position of the person in charge Liang Chenghui.

...

Five o'clock in the evening.

The heavy rain finally stopped, and the valley was foggy, as if it was a fairyland on earth.

At the entrance of the tunnel, when Gu Jingze led the Northwest Army to excavate the passage, he heard someone asking for help, so he stopped digging decisively and carefully identified the direction of the sound.

"Stop!"

"Everyone stopped!"

"Someone is calling!"

As Gu Jingze shouted, everyone stopped immediately.

"Save...help..."

"Click..."

A very faint sound came from the pile of gravels.

Gu Jingze pricked up his ears and listened carefully, and judged the position of the sound the next second.

"Duan Feng, Jiang Li, here!"

Gu Jingze called out three people, "Call someone to come and dig."

"yes."

"Brothers, come here to dig."

"It's not far from us, it's only about three or four meters away, be careful to dig."

"receive."

The Northwest Army quickly arrived at Gu Jingze's location on dozens of days and began to move the piles of stones.

Although the tunnel is crowded, everyone has their own duties, and they act very regularly, without any feeling of being crowded at all.

"save……"

"save……"

Gu Jingze came to the other side and listened to the sound again.

About twenty minutes.

The stones were cleared out, Gu Jingze signaled everyone to be safe, and quickly stepped forward and shouted loudly.

"Is anyone?"

"I know you're here, and you can make a sound if you can hear it."

In the tunnel, it was very, very quiet, everyone held their breath, waiting for the response of the trapped people.

One second or two passed, but there was still no movement.

Until five seconds later, a squeak came from the front right.

Gu Jingze stared carefully in front of him and looked through the sound and found the location of the sound.

Go up with a quick step, bent down to move the stone.

"Save...I..."

“Finally found.”

"Come here to help!"

"Swish swish swish swish!"
