On the morning of the 21st.

It was finally dawn.

Lin Feng took out the map.

On the map, it's just a small circle, looking like a small place.

But in fact, it is a place within a radius of more than ten miles.

It's still the old way, bury explosives in the ground and listen to the sound.

Wherever there is a cavity under the ground, it will produce a different sound.

Sound waves travel more slowly through the air,

The sound produced by the explosion travels through the mountain, and when it encounters underground space, it creates an echo.

In fact, this is part of the reason for the sonic lag.

At the same time, the stone walls in the cave also reflect sound waves.

Because of the extremely short period of time, the average human ear cannot distinguish it.

Even the most advanced acoustic detection instruments are difficult to detect.

Otherwise, these buried gold would have been discovered long ago.

Gradually, the gold of the little day became a legend.

Lin Feng's ears, once he concentrated, were even more agile than a dog.

The ability of living beings is beyond the reach of human technology at this stage.

Don't talk about Lin Feng, you can't even compare it with a dog.

Lin Feng put a drone, took pictures of the surrounding maps, and printed them into a drawing.

Then Lin Feng observed for a while and marked it on the map.

"Here, here, and here......"

"Uh-huh, uh-huh......" Liu Erwa kept nodding.

The place that Lin Feng marked with his pen was the place where it was blasted.

After explaining, Liu Erwa and Zhao Xiaoyang set off with backpacks.

Of course, Lin Feng was not idle, looking for traces that might have been left by the small days of decades ago.

It's been too long, it's been seventy years, and the forces of nature have long covered the traces of human beings.

Tang Mi took the metal detector and found a few rusty stainless steel pieces.

Unfortunately, this does not determine the exact location of the treasure cave.

A few decades ago, there were also many talents, and the site of each fortification was carefully explored and built extremely hidden.

This place has a special topography, which is actually a huge island, and the depth is not enough.

Once exposed, it is easy to be bombarded by the Mi people with aircraft and naval artillery.

After looking for a long time, Liu Erwa's side has already done it, and Lin Feng has not found a place.

Secretary Tang pouted and threw away the metal detector and some sonar instrument specially used for treasure hunting.

It's still the most advanced thing, but I haven't found it after looking for it for most of the day.

Ouyang Jasmine said with a smile: "If the treasure of Xiao Ri could have been easily found with these instruments, it would have been dug up a long time ago." ”

Tang Mi said: "That can only be heard with my ears, my ears are very smart." ”

Ouyang Jasmine glanced at Qi Yao, who was silent, and whispered in Tang Mi's ear, "Was it fun last night?" ”

Tang Mi smiled slightly, and raised his head slightly.

She didn't answer, but her expression was a little dazed.

This is also an answer.

Ouyang Jasmine pouted, thinking that I was also afraid of the dark, otherwise...... Hum!

At this time.

"Wow!"

Tang Mi suddenly let out an exclamation.

It turned out that there was a spider half the size of a palm lying on the ground next to her, which looked like it was poisonous, which startled her.

Ouyang Jasmine was stunned when she saw it.

What a scary big spider!

Qi Yao frowned slightly, took a few steps forward, and trampled the spider flat with a 'snap'.

Then he walked away without looking back, farther and farther away.

Except for cockroaches, Qi Yao is not afraid of anything else.

It took dozens of seconds for the two women to come back to their senses.

"It's so brutal!"

Ouyang Jasmine sighed.

Of course, she was talking about Qi Yao, because she was more afraid of Qi Yao than Tang Mi.

Thinking that when he was on the island, someone pretended to be a fisherman and wanted to get mixed up on the island, and after he died, Ouyang Jasmine saw Qi Yao holding a scalpel......

"Yes! It's like a robot with no fears. ”

Tang Mi's whisper echoed and made Ouyang Jasmine wake up from the 'terrifying' memories.

Ouyang Jasmine nodded, "In the future, we can't annoy her, otherwise we ......"

Ouyang Jasmine made a belly pulling motion.

Everyone is a woman, why is there such a big difference?

More than ten meters in front, Lin Feng was one step behind and walked side by side with Qi Yao.

He leaned into Qi Yao's ear and asked in a low voice, "Yaoyao, did you do it on purpose?" ”

"Huh?"

Qi Yao looked at Lin Feng and let out a small puzzled sound.

"Cool looking!" Lin Feng whispered.

"Why should I be cool?" Qi Yao asked softly.

Lin Feng nodded, "You're already cool, you don't have to pretend, they're afraid of you." ”

To put it mildly, Qi Yao never thought of pretending to be cool in front of them.

Because of disdain!

Lin Feng wondered when Qi Yao's title of 'boss' spread.

Looks like it started with Liu Zangyun, right?

To be the boss, of course, is not only to be beautiful and favored, but also to be convincing. ŴŴŴ.BiQuGe.Biz

Qi Yao's body naturally has a temperament that impresses them.

……

Ten minutes later, Lin Feng stopped, and there was a stone wall in front of him.

"That's it!"

Lin Feng said a word, then put down his backpack, picked up the walkie-talkie, and after turning it on, he immediately notified Liu Erwa and Zhao Xiaoyang.

At this time, Liu Erwa and Zhao Xiaoyang were already far away from the blasting point and were squatting under a tree to wait.

After getting the replies from the two, Lin Feng took out the remote control for detonation, and there were rows of buttons marked with numbers on it.

The front twelve buttons represent the twelve blast points.

After turning on the power of the remote control, Lin Feng put his ear on the stone wall.

Tang Mi was curious, and she was also like Lin Feng, she was very curious, listening to the voice to distinguish whether she would be able to.

"Boom~"

When Lin Feng pressed a button on the remote control,

To the northeast, a thunderous explosion sounded more than 1,000 meters away.

Lin Feng closed his eyes and focused all his attention on hearing.

Dozens of seconds later, Lin Feng frowned.

Then, he pressed the button again, and in the southeast direction, there was another explosion.

This time, Lin Feng's brows furrowed.

Finally heard the echo!

To be precise, it is the cavity inside the mountain, which creates an echo in the sound of the explosion.

Then, Lin Feng detonated three times in a row.

After three blasts, he basically settled on the location.

It turns out that the treasure cave is in the southeast, about a kilometer in the middle of the mountain.

The remaining blasting points were useless to Lin Feng.

But he couldn't keep it, so he detonated it all in one go.

"Little Secretary, did you hear anything?"

Ouyang Jasmine watched Tang Mi leave the mountain wall and asked with a smile.

Tang Mi shook his head, "I only heard the sound of boom bang." ”

Ouyang Jasmine pointed to her ear and said, "I heard it too." ”

Tang Mi was deflated, it turned out that his ears were normal.

But soon, she looked at Lin Feng with wide eyes, as if she had discovered a big secret about Lin Feng.

This guy has ears like a dog, so when he whispers from a distance, will he hear him?

Lin Feng said with a smile: "This depends not on how far you can hear, but on learning to distinguish sounds, after a long time of practice,

Ordinary people can learn it, and of course, they need a certain amount of talent. ”

Lin Feng would not admit that his ears were pointed, otherwise he would have lost a lot of fun in the future.

Only Qi Yao knew that Lin Feng was talking nonsense.

He has ears better than a dog.

Why justify?

It's not to listen to Tang Mi and Ouyang Jasmine and other little fools whispering.

More than half an hour later, Liu Erwa and Zhao Xiaoyang returned.

The six of them converged and walked towards the location identified by Lin Feng.

The road ahead was not easy to walk, and I made a big detour, and I arrived at two o'clock in the afternoon.

When he got closer, Lin Feng asked Liu Erwa to blast it twice, and more clearly determined the location of the cave and the closest place to the outside world.

After going around the peak, Lin Feng pointed to the hillside in front of him and said, "Just there, dig about ten meters, and you should be able to get in." However, it seems to be reinforced with a layer of concrete. ”

Now is not the time to dig.

In the evening, there are more people, a small excavator, a high-power generator, and a remote-controlled robot......

With the transportation capacity of Jasmine 1 and 2, a single transportation can turn this place into a construction site.

No matter how big the movement is, I am not afraid, because there are mountains for more than ten miles nearby.

……

A few hours passed quickly.

Night falls.

Two anti-gravity vehicles of the Jasmine arrived.

More than two dozen people, a large amount of equipment, completed the handling in half an hour.

Pulling the Jasmine away, more than two dozen people were either from the Tang family or the brothers of the Ouyang family.

It took more than two hours to dig a flat field on the hillside.

Then, using the most advanced excavation tools, a cave with a diameter of about three meters was dug.

After digging a distance of about ten meters in, a wall made of reinforced concrete appeared.

At this point, the work of these people is done.

It took more than an hour for more than two dozen people to leave on the Jasmine with unwanted equipment.

The busy construction site became silent in an instant.

Watching the two Jasmine disappear into the night sky, Lin Feng raised his wrist and looked at the time, it was just four o'clock in the morning.

Liu Erwa is still in good spirits.

A one-meter-thick concrete wall was blown up by blasting.

An eerie cave appeared.

"Woo~"

The air flow from outside poured in, and the sound of 'whining' wind sounded.

It sounds like a ghost is crying.

When Liu Erwa and Zhao Xiaoyang, who were closest to each other, heard this, they were scared in a cold sweat.

Muma!

It sounded terrifying.

This is the sound of the wind, it is clearly the cry of a woman, and the crying is still very miserable.

Sound alone is enough.

Something even scarier happened.

In the darkness, a red shadow flashed.

"Mom!"

Liu Erwa and Zhao Xiaoyang shouted at the same time, turned around and ran.

Lin Feng looked calm and said with a smile: "Yaoyao, these two guys are scared again, haha!" ”

Qi Yao turned his head and glanced at Lin Feng, "Are you cold?" ”

"It's not cold!"

"Your hands are shaking."

"Uh~ It's not that I'm afraid, it's excited!"

"Don't be afraid, there are no ghosts in this world." Qi Yao held Lin Feng's hand and whispered.

She was afraid that if she said it loudly, Lin Feng would lose face.

Although Qi Yao said this countless times.

But Lin Feng still believed that there were ghosts in this world.

He's almost certainly seen hell of it several times.

It's just that the ghosts are afraid of the town house beast around them, and they all run out, and there is really no ghost shadow.

The cry inside is that the ghost is really crying.

The ghost shadow that passed by was actually the ghost inside who panicked and scurried around.

……

It was dawning very quickly.

After the sun came out, Liu Erwa was bold and moved the blower to the entrance of the cave.

After activation, the outside air is blown into the cave at an accelerated pace.

In the process of ventilation, Zhao Xiaoyang put a remote-controlled robot and drove into the cave.

Outside, you can clearly see the situation inside the cave through the picture captured by the remote control robot camera.

"So many dead people!"

Liu Erwa looked at the laptop screen in front of her and frowned.

I saw on the computer screen, a skeleton wearing a military uniform in World War II.

Some lay on the ground, some leaned against the stone wall.

As for the method of death, some of the skulls had holes in them, apparently shot by bullets.

Others had a knife stuck in their belly, and the tip of the knife was still stuck in their vertebrae.

Some had their heads cut off, and the way of death was apparently to have their heads cut off.

You don't have to guess to know that these people must have been soldiers who were sealed inside together after carrying the gold in order to extinguish the mouth.

In a situation where there is no hope of survival.

Some help their peers solve it and then commit suicide.

Of course, there are also those who have struggled for a long time and suffocated to death.

From the black finger marks formed by blood on the stone wall, you can see how painful it is to be suffocated without oxygen.

This kind of pain is not only physical, but also psychological.

After more than an hour of exploration, the situation in the cave was basically determined.

The shape of the cave is in a zigzag shape.

Lin Feng's entrance that they blew out was at the very bottom of the zigzag.

The robot did not find the gold, because in this zigzag cave, there are many closed iron gates.

It's time to get in.

Once the gold is found, it can be transported at night.

This is just one of dozens of treasure spots, and there are many more to come.

There was a two-day delay here, and the longer it dragged on in other places, the more likely it was to be exposed.

The next step is to enter the cave and open the iron gates.

While making preparations, Liu Erwa frowned and said, "There are corpses inside, scattered guns, and ammunition boxes......

But what was the red shadow seen last night and where? ”

Qi Yao explained aloud: "This is an illusion formed by our vision, you turn on the flashlight, shine your eyes, and then look inside." ”

Liu Erwa did so.

Then he looked at the dark cave, and sure enough, a cloud of red appeared in his sight.

"I see!"

Liu Erwa scratched her head and suddenly realized.

Then, Liu Erwa put on an oxygen mask and was the first to rush in.

Lin Feng shook his head.

This is a fool!
