Chapter 438: The Amazing Sea Conch Shell

Liu Erwa, who was lying on the ground, began to convulse, and the look of terror on her face had not faded.

Lin Feng crouched down, slapped Liu Erwa a few times, and woke her up.

"Brother Feng... ah!"

Seeing Lin Feng, Liu Erwa let out a wail and fainted again.

"This guy still has nightmares after fainting."

Lin Feng shook his head and took a half‑drunk bottle of mineral water from the satchel slung on Liu Erwa's back.

He unscrewed the cap and poured it onto Liu Erwa's face.

After waking again, Liu Erwa finally became fully conscious.

"What did you see to be so scared?"

Lin Feng was very curious.

Liu Erwa is usually fearless.

"Uh... you, Brother Feng, buried me alive..."

Liu Erwa said weakly.

Lin Feng was stunned.

It really was a terrifying thing.

It was probably something that frightened Liu Erwa deep in her heart.

"As long as you don't betray me, why would I bury you?"

Lin Feng tapped Liu Erwa on the head.

Liu Erwa scratched her head and giggled, "That's also true!"

Next, it was time for Qi Yao to decipher.

Holding a flashlight, they searched the cave for a long time, but it was Lin Feng who discovered the mechanism.

Next to it, a golden statue had a ferocious face and an open mouth.

Lin Feng looped a rope around the statue's head and climbed up to take a look.

The statue's head was hollow; when knocked, it produced an empty sound.

Then he pried a manually processed Sea conch shell out of its mouth.

Lin Feng jumped off the statue holding the Sea conch shell.

Qi Yao looked over and said, "There are many sounds we can hear and things we can see in this world.

But the brain prevents us from hearing and seeing them.

The space here was originally sealed, but now it is open.

When the airflow moves, it causes this Sea conch shell to emit a sound of a special frequency.

We think we cannot hear this sound, but the brain actually receives it.

At the same time, this frequency has a hypnotic effect, making people disoriented and hallucinate...

However, it only works once on the same person. The next time, the brain will develop a defense and ignore the sound."

Lin Feng nodded.

Qi Yao's explanation was very reasonable.

"This is truly a treasure!"

Lin Feng told Liu Erwa to put it into her pocket.

This thing can kill people invisibly.

It's also unknown whether it will still be effective after being taken out.

"I almost died of fright just now, thinking that..."

Lin Feng muttered, shaking his head.

Liu Erwa widened her eyes and stared at Lin Feng.

I didn't expect the Great Demon King to fall for it too.

"Professor Qi, you weren't scared, were you?"

Liu Erwa asked curiously.

Qi Yao shook her head.

The House Guarding Divine Beast is not affected by this sound.

Unless you catch a cockroach and put it on it...

The three continued forward.

Lin Feng asked Qi Yao, "You just said that we actually see and hear a lot, but the brain doesn't let us notice, of course to protect us.

Is it possible that, in fact, ghosts are everywhere in this world.

Or other terrifying spirit beings that we originally saw, but the brain actively blocks?"

When Lin Feng finished speaking, Liu Erwa was startled.

Qi Yao shook her head, "I don't know either!"

"Brother Feng, I'm scared..."

Liu Erwa suddenly said.

"What are you scared of, a ball!"

Lin Feng glared at Liu Erwa.

Liu Erwa said, "My dad, who drove a truck, died in a crash, and my brother was also in the car. I often dream of them. Do you think the two of them are always following me?"

"Your dad and brother died so long ago, they've probably been reincarnated by now!"

"That's right!"

After that, no strange things happened.

Inside the cave, the statues grew more and more, and skeletons appeared one after another.

Upon reaching the end, a large pool appeared before them.

The water in the pool kept surging; Lin Feng could hear the sound of flowing water beneath his feet without having to press his ear against the stone wall.

There should be an underground river below.

He looked up again.

Countless metal pieces hung from the cave ceiling, all suspended by red silk.

When the air moved, these metal pieces — no, they should be gold pieces — would collide with each other, producing a strange sound.

Besides the airflow, the thunder outside could also cause the gold pieces to vibrate.

This was also the sound Lin Feng had heard when the gold pieces collided during the previous thunder.

"Brother Feng, do you think this is Genghis Khan's tomb?"

Liu Erwa asked curiously.

Lin Feng shook his head. "No, this cave is far older — at least over a thousand years, while Genghis Khan died less than eight hundred years ago. Strangely, there are incantations here similar to Mongolian script."

This world has many mysteries.

For example, the Three Star Mound.

Now there is another mystery: how did people from several decades ago get in here?

After searching around, Lin Feng turned his gaze to the pool before him.

Could those people have come in by diving?

After thinking, Lin Feng shook his head again.

No.

Back then there was no advanced diving equipment; it was impossible for a person to hold their breath and pass through the long underground dark river.

The most likely possibility is that they, like Lin Feng, dug a hole to get in.

Liu Erwa laid out the wires, and soon lit up the entire cave.

Except for a few blind spots, this underground space, over three hundred meters long, irregular in shape and sloping downward, was bathed in bright light.

While Qi Yao and Lin Feng inspected the surroundings, Liu Erwa shone his flashlight on those dark corners.

Soon he made a discovery.

"Brother Feng, come over quickly!"

Liu Erwa shouted.

Lin Feng ran over and saw a cave just big enough for one person to pass through appear before his eyes.

"I'll crawl over and take a look!"

Liu Erwa said, and crawled in.

Having learned much scientific knowledge, Liu Erwa became much bolder.

He had a rope tied to his body.

Lin Feng slowly loosened the rope at the cave mouth, not letting it run too fast.

After several minutes, the rope moved twice.

Lin Feng immediately reeled in the rope.

After another ten or so minutes, Liu Erwa's head emerged first.

"Brother Feng, outside is a wide stone crack; I don't know how far it goes — some places are narrow, some wide, and some are bottomless..."

Liu Erwa said, picking up his phone and opening the photo he had taken to show Lin Feng.

At that moment, a 'splash' sound came from beside the pool.

Lin Feng turned his head and saw Qi Yao gripping a rust-streaked metal chain in her hand.
