Chapter 585: Where Is the Red Shadow?

Morning of the 21st.

The sky finally brightened.

Lin Feng took out the map.

On the map, it was just a small circle, looking like the area wasn't big.

But in reality, it was a place spanning ten or so li in radius.

Still the old method: bury explosives on the ground and listen for the sound.

Anywhere there is a cavity beneath the ground, it will produce a different sound.

Sound waves travel more slowly in air,

the sound of the explosion propagates through the mountain, and when it encounters underground space, it produces an echo.

This is actually the reason for part of the sound wave delay.

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

Because the time interval is extremely short, ordinary people's ears cannot distinguish it.

Even the most advanced sound wave detection equipment finds it hard to detect.

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

Gradually, the Japanese gold also became a legend.

Lin Feng's ears, once focused, are even more sensitive than a dog's.

Biological capability is something modern human technology cannot reach.

Not to mention Lin Feng, even compared to a dog it falls short.

Lin Feng launched a drone, captured the surrounding area on film, and printed it into a map.

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

"Here, here, and here..."

"Mm, mm, mmm..." Liu Erwa kept nodding.

The spots Lin Feng marked with a pen are the blasting sites.

After giving the instructions, Liu Erwa and Zhao Xiaoyang set off with their backpacks.

Lin Feng, of course, wasn't idle; he searched nearby for traces that the Japanese might have left decades ago.

Too much time has passed—seventy years—and nature's power has long since covered any human traces.

Tang Mi, holding a metal detector, did find a few specks of rust-stained stainless steel.

Unfortunately, this cannot confirm the exact location of the treasure cave.

Decades ago, the Japanese also had many talents; each fortification site was chosen after careful survey and built to be extremely concealed.

This place has a unique terrain; it is actually a large island, lacking sufficient depth.

Once exposed, it would easily be bombed by Americans with aircraft and naval guns.

After searching for half a day, Liu Erwa's side was already settled, and Lin Feng hadn't found a spot.

Tang Mi pursed her lips and threw away the metal detector, as well as whatever sonar device used for treasure hunting.

Despite being the most advanced equipment, after searching for most of the day, they still found nothing.

Ouyang Moli laughed and said, "If the Japanese treasure could be easily found with these instruments, it would have been dug up long ago."

Tang Mi said, "Then we can only listen with our ears; my ears are very sensitive."

Ouyang Moli glanced at the silent Qi Yao, leaned close to Tang Mi's ear, and whispered, "Was last night fun?"

Tang Mi smiled faintly and lifted her head slightly.

She didn't answer, but her expression was a bit smug.

That, too, is a kind of answer.

Ouyang Moli pursed her lips, thinking, "I'm also afraid of the dark; otherwise... hehe!"

Just then.

"Wow!"

Tang Mi suddenly let out a startled cry.

It turned out a spider half the size of a palm was lying on the ground nearby; at first glance it looked poisonous, giving her a big fright.

Ouyang Moli looked and also froze in place.

What a terrifying huge spider!

Qi Yao frowned slightly, stepped forward a few paces, and with a "pop" flattened the spider.

Then she walked away without looking back, going farther and farther.

Besides cockroaches, Qi Yao fears nothing else.

After several tens of seconds, the two women finally came to their senses.

"Too brutal!"

Ouyang Moli exclaimed.

She was of course referring to Qi Yao, because she fears Qi Yao even more than she fears Tang Mi.

Back when they were on the island, someone disguised as a fisherman tried to sneak onto the island, died afterward, and Ouyang Moli personally saw Qi Yao holding a scalpel...

"Yeah! Like a robot without any fear."

Tang Mi's soft agreement let Ouyang Moli snap out of her "horrifying" memory.

Ouyang Moli nodded and said, "From now on, we must not provoke her, otherwise..."

Ouyang Moli made a belly‑scratching motion.

We're all women, why is the difference so great?

A few meters ahead, Lin Feng lagged a step behind, walking side by side with Qi Yao.

He leaned close to Qi Yao's ear and whispered, "Yao Yao, are you doing this on purpose?"

"Hmm?"

Qi Yao looked at Lin Feng and made a small sound of doubt.

"Acting cool!" Lin Feng whispered.

"Why would I act cool?" Qi Yao asked softly.

Lin Feng nodded, "You're naturally cool; you don't need to act, they're already afraid of you."

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

Because she scorns it!

Lin Feng wondered when the title "boss" for Qi Yao had spread.

It seems to have started from Liu Cangyun, right?

To be the boss, it's not just about looking beautiful and being favored; one must also convince others.

Qi Yao naturally possesses a temperament that makes them submit.

After a few minutes, Lin Feng stopped, and before him was a stone wall.

"Right here!"

Lin Feng said that, then put down his backpack, picked up the walkie-talkie, turned it on, and immediately notified Liu Erwa and Zhao Xiaoyang.

At that moment, Liu Erwa and Zhao Xiaoyang had already moved away from the blast point, crouching under a tree on standby.

After receiving their replies, Lin Feng took out the detonation remote, which had rows of numbered buttons.

The twelve buttons ahead corresponded to the twelve blast points.

After turning on the remote's power, Lin Feng pressed his ear against the stone wall.

Tang Mi was curious, imitating Lin Feng; she was very curious whether she could also locate by sound.

"Boom~"

When Lin Feng pressed a button on the remote,

a muffled thunder-like explosion sounded from the northeast, over a thousand meters away.

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

After several tens of seconds, Lin Feng furrowed his brow.

Then he pressed the button again; an explosion sounded from the southeast.

This time, Lin Feng's brow relaxed.

Finally, he heard the echo!

Precisely, the echo was produced inside the mountain due to a cavity when the blast sounded.

Then Lin Feng detonated three times in succession.

After the three blasts, he basically confirmed the location.

As it turned out, the treasure cave was in the southeast, within the mountain about a kilometer away.

The remaining blast points were now useless to Lin Feng.

But they couldn't be left, so he detonated them all at once.

"Little Mi, did you hear anything?"

Ouyang Moli watched Tang Mi leave the stone wall and asked with a smile.

Tang Mi shook her head, "I only heard the booming sound."

Ouyang Moli pointed to her own ear and said, "I heard it too."

Tang Mi let out a breath; it turned out her ears were normal.

But soon she widened her eyes at Lin Feng, as if discovering a big secret about him.

"This guy's ears are as sharp as a dog's; if I whisper from afar, will he hear it?"

Lin Feng laughed and said, "It's not about how far you can hear, but learning to distinguish sounds; after long practice,

ordinary people can learn it, of course, also requiring some talent."

Lin Feng wouldn't admit his ears are sharp, otherwise he'd lose a lot of fun later.

Among those present, only Qi Yao knew Lin Feng was just talking nonsense.

He clearly has ears sharper than a dog's.

Why bother explaining?

It's just so he can eavesdrop on Tang Mi, Ouyang Moli, and these little fools whispering.

After more than half an hour, Liu Erwa and Zhao Xiaoyang returned.

The six gathered and walked toward the location Lin Feng had identified.

The road ahead was rough; after a big detour, they arrived at two in the afternoon.

Upon approaching, Lin Feng had Liu Erwa blast twice more, clearly confirming the cave's location and the point nearest the outside.

After circling the peak, Lin Feng pointed to the slope ahead and said, "There, dig about ten meters or so, and we should be able to get in. However, it seems a layer of concrete has been laid inside for reinforcement."

Now is not the time to dig.

Wait until evening, when there will be more hands, a small excavator, a high-power generator, remote-controlled robots…

With the transport capacity of Moli No. 1 and No. 2, one trip could turn this place into a construction site.

No matter how big the commotion, we're not afraid, because the surrounding area for dozens of kilometers is all mountains.

A few hours passed quickly.

Night fell.

Two Jasmine anti-gravity aircraft arrived.

Twenty-something people, a large amount of equipment, completed the move within half an hour.

Pulling the Jasmine away, twenty-something people who were either from the Tang family or the OuYang family brothers began to work busily.

After more than two hours, they dug out a flat area on the hillside.

Then, using the most advanced excavation tools available now, they dug a cave about three meters in diameter.

After digging further inward about ten meters, a wall made of poured reinforced concrete appeared.

Having reached this point, their work was considered complete.

After spending more than an hour, twenty-something people took the unnecessary equipment and left aboard the Jasmine.

The busy construction site instantly became completely silent.

Watching the two Jasmines disappear into the night sky, Lin Feng raised his wrist to check the time—it was exactly 4 a. m.

Liu Erwa remained very energetic.

Using blasting, they destroyed a concrete wall at least one meter thick.

A gloomy, dark cave appeared.

"Woo~"

Outside air flowed in, producing a "woo-woo" wind sound.

It sounded like a ghost crying.

Upon hearing it, Liu Erwa and Zhao Xiaoyang, who were closest, broke out in cold sweat from fright.

Damn!

That sound is really too scary.

This isn't wind noise; it's clearly a woman's crying, and it's terribly miserable.

Just the sound alone would be enough.

Then something even scarier happened.

In the darkness, a red shadow flashed by.

"Mom!"

Liu Erwa and Zhao Xiaoyang both shouted loudly and turned to run.

Lin Feng, however, remained calm, smiling and saying: "Yao Yao, these two guys got scared again, haha!"

Qi Yao turned her head to look at Lin Feng and asked, "Are you cold?"

"Not cold!"

"Your hand is shaking."

"Uh~ not fear, it's excitement!"

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

She was afraid that speaking loudly would cause Lin Feng to lose face.

Although Qi Yao had said this many times before.

But Lin Feng still believed that ghosts exist in this world.

He could almost certainly say he had seen ghosts several times already.

However, the ghosts were all afraid of this House Guarding Divine Beast beside him, so they all fled, leaving not even a ghostly shadow.

The crying inside was truly ghosts weeping.

That flashing ghostly shadow was actually the panicked ghosts inside running around wildly.

The sky soon grew bright.

After the sun came out, Liu Erwa mustered his courage and moved the blower to the cave entrance.

After starting it, outside air blew into the cave at an accelerated pace.

During the ventilation process, Zhao Xiaoyang placed a remote-controlled robot and sent it into the cave.

From outside, people could clearly see the interior of the cave through the images captured by the remote-controlled robot's camera.

"So many dead people!"

Liu Erwa looked at the laptop screen before him, furrowed his brow, and said.

All that could be seen on the computer screen were skeletons dressed in World War II-era Japanese military uniforms.

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

As for the cause of death, some had a hole in the skull, obviously from a bullet.

Others had a knife stuck in their abdomen, the tip still lodged in the vertebrae.

Still others had their heads severed, the cause of death clearly being decapitation.

No need to guess; these people must have been soldiers who, after transporting gold, were sealed inside together to prevent leaks.

In a situation where there was no hope of survival.

Some helped their companions end their lives, then committed suicide themselves.

Of course, some struggled for a long time and eventually suffocated to death.

From the dark, blood-formed fingermarks on the stone wall, one can see how painful it was to suffocate without oxygen.

Such suffering was not only physical, but also psychological.

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

The cave's shape is like a 'zi' character.

The entrance that Lin Feng and the others blasted open is at the lowest part of the 'zi' shape.

The robot found no gold, because in this zi-shaped cave there are many sealed iron doors.

We should go in.

After finding the gold, we can transport it at night.

This is only one of dozens of hidden treasure spots; there are many more ahead.

We've been delayed here for two days; if we do the same elsewhere, the longer we linger, the greater the chance of being exposed.

Next we enter the cave and open those Iron Doors.

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

"But what was the red shadow we saw last night, and where is it?"

Qi Yao spoke up and explained, "It's a visual illusion we created; turn on your flashlight, shine it on your own eyes, then look inside."

Liu Erwa did as instructed.

Then they looked toward the pitch‑black cave, and indeed a clump of red appeared in their sight.

"So that's how it is!"

Liu Erwa scratched their head and suddenly realized.

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

Lin Feng shook his head.

This simpleton is really easy to fool!
