showdown!I enjoy life on the island

Otherwise, I would have to die here today.

The boys' dormitory doesn't have the same effect!

If it weren't for the beeswax candle inside the wind lamp, when it was burning, it could still emit a faint fragrance, which partially covered the smell in the environment.

I'm afraid Xu Le has already started planning to go back home.

"It smells bad, but there is no gas like methane." Xu Le pinched the finger on his nose to loosen a small slit, and said sullenly.

If anything, the flames of wind lamps and steam engines would bear the brunt of the impact.

The damage to the body caused by this environment will also activate the [Extreme Recovery] skill.

These two conditions for judging whether the air is dangerous or not are all silent, so the nose suffers a bit, but the left and right are not dangerous.

Xu Le felt that he could continue to explore further.

The candle has been replaced for the second time, but the fuel inside the funeral is still resistant to burning. Under such circumstances, high-quality charcoal has shown excellent reliability.

The surrounding rock walls extend all the way down, and there are no big branch routes, occasionally there are some cracks, and they have not reached the point where people can pass.

The cave also maintains a general straightness, which is extremely rare in naturally formed structures.

If it weren't for [Earth Resonance] not feeling too complicated a structure, Xu Le would have been able to excavate a part of this cave manually.

But not.

This is a hole torn by the mighty force of nature on the island.

The two went down all the way, Xu Le estimated as he walked, the cave should have almost extended to the center of the island now.

Apart from an earthquake or a large undersea volcanic eruption, no other force can cause so much damage to an entire island.

So human beings are like younger brothers compared to nature... Xu Le complained in his stomach, sighed and raised the lantern, trying to illuminate a wider range.

In the roar of the funeral just now, he caught a trace of abnormal echo.

[Sound of Nature] brings him a keen sense of hearing, which can not only capture subtle sounds, but also slight changes in the sound.

In the reverberation he heard now, apart from the sound waves reflected by the two walls of the normal cave, there was also a more hollow reverberation.

This kind of mixing requires a resonance chamber as large as a football field, which cannot be provided by the tunnel where the two are currently in.

"Is there a big open space in front?" Xu Le muttered, shaking the lantern.

"And? How far is it?"

Lin Xihan didn't question it, but continued what Xu Le said just now, "Could it be some kind of animal's nest inside?"

She held Zhuge Lianshi behind her.

"In terms of distance, it should be less than one kilometer."

Xu Le listened silently for a while, then shook his head, "Don't be nervous, I don't feel anything alive."

It doesn't matter if there are living creatures, there is nothing that two cannonballs can't solve.

No, just two rounds.

If it doesn't work, [overload].

If you can't fight again, give up first, make more cannons later, and wash them again when you come back.

The monks can't run away from the temple, anyway, the island is so big.

Besides...Xu Le shrugged, [Danger Perception] didn't respond again, this wave is worthwhile, A will get it if he goes up.

The tunnel in front of him gradually became wider. He advanced a few steps and then stopped, picking up a small stone from the ground.

By the light of the fire, you can see the metallic luster on the surface of the stone.

It's a bright blue-purple, mixed with some equally dazzling yellow and green, and it looks pretty good.

"Hey, is this a piece of copper ore?" Xu Le checked it over and over again, and made a judgment based on his [Geology] skill.

"And it's chalcocite, which is enough for industrial copper production. Chalcocite is generally of endogenous hydrothermal origin. It seems that this place has been arched by magma."

He looked around again, and added: "At least it was arched by magma before."

Barrage--

"So Xu Shen can use the bronze vessel?"

"It's not necessary, there are already iron products, so it's not necessary to make a replacement."

"What is endogenous hydrothermal origin?"

"Almost after the magma crystallized, various high-temperature steam inside invaded the surrounding cracks and formed through a series of physical and chemical reactions."

"I don't understand, DJ cuts singing boots."

"..."

Generally speaking, in the process of civilization, the application of bronze ware is before iron ware, which is caused by the limitation of smelting technology.

Copper has a much lower melting point than iron.

However, Xu Le's ventilated furnace did not follow common sense, and smelted iron ore at high temperature, making great strides into the Iron Age.

It is only now that copper ore has been found. For Xu Le, the value of this material has plummeted.

"But let's keep it, the texture of copper is softer than iron, and it may be useful on some workpieces."

As he spoke, he rummaged through the gravel on the ground, gathered a small handful, and stuffed them into the leather bag on Lin Xihan's back.

The corners of Lin Xihan's eyes twitched: "You can't put it on the funeral?"

"Isn't that worried about consuming fuel and shortening battery life?" Xu Le was confident, "And there is no place to put fuel for weapons and ammunition at the funeral."

"How much space does a piece of copper ore take up..." Lin Xihan stared.

"Then help me to recite it, you have great strength." Xu Le smiled harmlessly.

Hiss...the teeth itch.Lin Xihan shook his fist fiercely.

Xu Le smiled and pointed forward: "Look, the front is the open land I just mentioned."

I can't see anything... Lin Xihan followed the direction Xu Le pointed and raised the lantern.

A slight light of fire fell into the darkness ahead, refracted by unknown ore, and a faint fluorescence was slowly released in the dark space.

Fluorescence is very dim, but enough to outline the surrounding scene.

"Maybe some kind of mineral, maybe a gemstone."

The funeral continued to move forward, the roar reverberated, the flames were further refracted, and the surrounding fluorescence was steadily increased to the point where the vision could function.

The fluorescent color is reddish and warmer, but because it is too thin, it can't bring any warmth to people.

Instead, the whole cave has a gloomy feeling, like entering a haunted house

Barrage in the live broadcast room——

"Shouldn't the fluorescence be blue and faint?"

"Generally, the wavelength of fluorescent light is longer than that of absorbed light. The light from wind lamps and stoves is orange-red, which is basically the hue of fluorescent light."

"What ore?"

"Ruby, emerald, etc., it's hard to say, I don't have a detailed spectrophotometer, so I don't know."

"ruby!"

"Emerald!"

"It's outrageous, you can find rubies by just exploring the cave?"

"Come, come, after the emerald, I have been waiting for God Xu to dig a new gem!"

"However, high-quality gemstones are not so easy to find."

"Brother Chest, if it is really a ruby, how many rubies must there be in such a large rock formation around here?"

"..."

Xu Le slowly illuminated with the wind lamp in his hand, and while walking along the edge of the rock wall, he said, "There are so many rubies."

He casually knocked off a small piece of rock with a hammer, and the stone was wrapped with fine ruby ​​crystals.

Although the crystal grains are embedded in the stone, they are ruddy in color and shine brightly under the firelight.

The size is not outstanding, but...

I can't stand the amount of it.

At this moment, looking around, you can already see bright spots like stars, extending from the ground to the dome.

Although sparse, but under such a large area, the number is extremely impressive.

Basically, as long as Xu Le can dig them out, all these rubies will belong to him.

This is much more exaggerated than the previous emeralds!

Barrage--

"That's right... Hundreds of millions!"

"More than that! The emeralds before were just two pieces of ore. The ruby ​​now is almost a whole mine!"

"hiss……"

"Is it too late to sign up for Desert Island Survival?"

Chapter 332 Cave Dive

Barrage--

"With such a whole ruby ​​mine in hand, I'm afraid Xu Shen can be a hero."

"Hundreds of millions? The value of the entire mine deposit must be at least one billion!"

"I'm afraid it's not that simple. Excavation and mining is a big project."

"But even if only the best-looking ones are dug up, it's worth a million dollars!"

"I want to be on the show too!"

"Come on, people's physiques can't be generalized. The buddies in the live broadcast room on the 69th haven't started a fire for a month, and they almost vomited from eating raw food."

"Not everyone can make such great progress for a whole year like Xu Shen!"

"I'm envious if I don't come, I'll just wait for Xu Shen's one-year term to expire and come back to pick up my thighs at the airport!"

"Look at your pursuit."

"What is Xu Shen going to do next?"

"Continue to explore the cave? But it feels like the cave has come to an end, there is no way."

"Why did the rhino go berserk? The dog's eyes were blinded by the ruby?"

"Why did the female rhinoceros go berserk? Why did her cubs appear in other people's homes? Let's discover the unknown story behind it."

"It's burning up! It's burning up! The green grassland!"

"Sorrowful Wind God Sect!"

"..."

When the old pigeons in the live broadcast room were busy and out of tune, Xu Le was pacing slowly, rubbing his chin.

He went around the cave, but found no other passages.

In other words, there is no tunnel enough for people to pass through.

There are only some thin cracks, estimated to be only big enough for a black-footed cat like Xiao Hei to pass through, and there is no possibility of detection.

Lin Xihan held up the lantern, she was not interested in the ruby ​​veins in the entire cave.

At this moment, she is very focused, looking around carefully, she is simply a curious baby.

Exploration first, the rest aside.

She tapped the stone wall with the back of the lancet knife, trying to find the hollow behind the stone wall through the echo.
