The Nordic text volume 466 of the Immortal Gate. The golden ore was faintly visible from the depths of the cave. Neither the musk ox herd nor Chen Song and his gang came in.

Humans and animals have natural fears about the wet and dark caves. Even if the sky is not dark yet, they are still unwilling to enter the depths of the caves.

However, after hearing this strange sound, they had to go in and take a look. They must stay overnight tonight and ensure the safety of the cave.

Someone fired a wolf's eye flashlight, and the snow-white cold light shone in, and the not-so-deep cave was illuminated.

There is nothing inside, it is just frozen stones. Although there are some raised stones and icicles on the ground and walls, it cannot hide humans and beasts.

"So where did the sound come from?" Chen Song asked.

Suriname scratched his head and said, "Damn it, this is really weird, but it must have nothing to do with ghosts, ghosts, monsters, etc. We have to believe in God."

Beaufort couldn't help saying, "Shut up, brother, if we want to believe that God exists, then ghosts and ghosts will exist."

"Is it time to discuss these topics? Who said that this matter is related to ghosts? You are all damn old-fashioned adventurers. Don't you know that we are the world of science?" Eric said angrily.

"Okay, stop making noise. Go and see where the sound is made. The sound is quite regular and doesn't sound like the sound of the wind." Angelina mediated from it.

Portis looked at Brother Bai and said, "This is the territory of the polar bear. Why not let your pet go over and take a look first? What I mean is that if there is something hidden in the cracks of the stone or under the stone, then we will be safer if there is a polar bear to explore the way."

Chen Song said unhappily: "Why don't you take risks yourself? Your life is life, but my bear's life is not life?"

Brother Bai stood beside him and was as tall as him. He put his claws on Chen Song's shoulder and stared at Portis unhappily. This guy was very good at observing his words and realized that Portis had a bad relationship with his own side.

Portis dared not offend Chen Song, let alone offend the polar bear.

Bears are creatures that exist at the top of the food chain, and polar bears are the number one beast in the bear family. They are naturally excellent wrestlers, and there are ten likes like Portis that are not enough for him to fall.

Eric was a real adventurer, so he didn't believe there was danger in the cave, so he took the initiative to hold up his flashlight and lower his lower body into the depths of the cave to check.

Chen Song followed, and then heard the sound becoming clearer.

Eric's flashlight kept passing through the four walls of the cave. After about half a minute, he breathed a sigh of relief: "So that's the case, I found the reason."

Chen Song asked: "What's the reason?"

The others followed suit.

Eric pointed to a gap at the bottom of the cave and said, "You feel it carefully, the sound comes from here."

This gap is about half a meter long and one or two centimeters wide. It is difficult to detect if you don't look carefully.

While speaking, Eric took out a napkin and covered it with the gap. Then the napkin was blown up and then sucked into the gap, which was quite magical.

Chen Song wondered, "Why do I feel like I can't hear that sound after getting close? Are you sure it came from this gap?"

Eric said confidently: "I'm sure that the reason why I can't hear clearly when I'm too close is because the sound itself is not loud, but the cave is constructed in a strange way. After the sound waves are emitted, they resonate with the cave itself and amplify the tone, which appears as a regular breathing sound."

The group left the bottom of the cave and walked out, and they gradually heard the sound of panting again.

Seeing everyone convinced, Eric felt very proud. Yesterday Chen Song found gold, Suriname found ivory, but he got nothing as the leader, which hurt his self-esteem.

Pointing to the gap, he said proudly: "I know this geology, which is geographically called the resonant vocal cliff cave. I bet that if we explore this gap, we will find it very deep and very narrow."

"These gaps extend outward and eventually communicate with the outside world. After a blizzard, strong winds will blow in, and then pressurize air to spray out from this opening to make a sound. But the storm blows rhythmically like the waves. When the wind retreats, the pressure inside the space becomes smaller, and air will be replenished from the cave."

"That's it, you know, the storm is like a piston twitching back and forth in the gap space, which causes the regular breathing we hear."

Suriname suddenly said, "So that's how it is."

"You know so much." Portis said in admiration.

Eric smiled confidently and said, "If you like to read more books, you won't know less than me, and I dare to assert that if we light a fire in the cave to warm up the air in the cave, then the gasp will be louder."

"It's always uncomfortable to hear this sound in this environment. Man, is there any way to calm it down?" Trickron asked.

Eric said: "It's a bit difficult, but it should be possible. We use ice axes to destroy the shape of the gap. The sound they can make has a lot to do with the width of the gap in the opening. If they are destroyed, there shouldn't be any strange sounds."

There were not many such gaps in the cave. They carefully searched and found four gaps in total, and then waving the ice axe and chiseled them up.

The musk oxen silently turned around and continued to aim the horns at them.

Because of the ice for millions of years, it is difficult to open up the cave stones wrapped in frozen ice, and they are very hard.

After working for a while, someone suddenly shouted, "Hey, am I dazzled? This ore, look, this ore is golden. I dug a gold mine? God, I dug a gold mine?"

Everyone was excited when they heard this, Eric strode over and asked, "What did you say? Man, what's going on?"

The young man named Longte excitedly spread his hands and showed him the gravel in his palm. The snow-white lights hit it and emitted a scattered golden yellow color with a very clear metallic luster.

"Is this gold ore? My God, my God, guys, I'm developed, no no, no, we're developed, I dug up gold mines, right? There's a gold mine here!" Longt shouted excitedly.

The group, including Chen Song, were also excited after seeing this scene. They rushed to grab the ores and said, "Let me see, let me see. Oh my God, they are so beautiful, have we found the gold mine?"

Angelina was quite sober, and she said, "Calm down, everyone, calm down, listen to me, Shakespeare has a famous saying, 'Not all shining things are gold'. There are many yellow metal ores in nature, and are there several copper ores that wrong? So we have to calm down first!"

"I can't calm down, I can't calm down, we are going to make a fortune! Billionaire, we are going to become the richest man in Iceland, ahha!"
