Brush!

After Lin Luo rode Zixiao all the way for nearly twenty minutes, he suddenly felt a wave of heat rushing towards him.

It's here!

Suddenly, Lin Luo's heart sank, knowing that he had arrived at his destination.

"Lin Luo, take off the animal skin!"

Sure enough, the team quickly stopped, and Wu's voice rang out.

Hearing this, Lin Luo immediately took off the animal skin covering his face and found that they were in a wide cave at the moment.

However, the temperature here is even higher than outside, and Lin Luo estimates that it is at least above 60°C.

"Wu, are we going to go into this cave on a mission?"

Lin Luo turned over and got off Zixiao's back, and asked Wu knowingly.

"That's right. ”

Wu nodded lightly in response.

"Why is it so hot in this cave, what are we going to do inside?"

Immediately, Lin Luo continued to ask.

Although Lin Luo had already guessed, the Yan Cave in front of him led to the interior of the volcano underground.

However, until now, it was not known what the so-called dangerous mission was.

"You'll know when you get there. ”

Although they had already reached the entrance of the cave, Wu still did not tell Lin Luo the specific content of the mission.

He just took out a clay pot the size of a baby's fist from his arms, handed it to Lin Luo and said, "It's going to be even hotter in this cave, you can drink this first!"

"Good. ”

Hearing this, Lin Luo didn't ask any more questions, and reached out to take the small clay pot.

The stopper of the clay pot was opened, and there was a light blue spiritual liquid inside, and Lin Luo directly raised his head and poured it into his mouth.

Suddenly, a cool feeling spread throughout his body, making him feel less hot and dry in an instant.

Obviously, this is a kind of spiritual fluid that has a cooling effect.

Lin Luo didn't drink all the light blue spirit liquid, and after drinking half of it, he handed the other half to Zixiao beside him.

At this time, Zixiao had already used his claws to tear off the animal skin covering its head.

Seeing the spiritual liquid handed by Lin Luo, it directly opened its big mouth and asked Lin Luo to pour all the remaining spiritual liquid into its mouth.

While Lin Luo was taking the spiritual liquid, the rest of the team also took out small clay pots and took the light blue spiritual liquid.

After that, Wu Cai waved his hand and said, "Go, enter the cave!"

"Yes. ”

Everyone nodded in response, and followed Wu towards the cave.

As Lin Luo had guessed before, the Yan Cave was a cave that extended significantly downward.

And, as we go deeper, the temperature inside the cave also rises.

As the temperature climbs, the cave becomes darker and darker.

Seeing this, Wu at the front immediately spoke: "Lighting!"

Hearing Wu's order, everyone took out a green plant stalk and gently tapped it on the cave wall next to it.

What's going on?

Looking at everyone's movements, Lin Luo's face was suddenly full of puzzlement.

I don't understand what this has to do with the lighting order given by Wu.

But the next moment, Lin Luo's eyes widened.

Because, after being tapped, the green plant stalks began to emit a brilliant green light, illuminating the originally dark cave.

Is this a glowstick?

Seeing this scene, Lin Luo thought in his heart full of surprise.

He really didn't expect that those very ordinary-looking plant stalks would have the same effect as glowsticks.

Even, the light emitted is even brighter than the glow stick.

"Lin Luo, give!"

At this time, Wu also took out a plant stalk and handed it to Lin Luo.

"No, I have lighting tools. ”

Lin Luo shook his head lightly and took out the fluorescent stone from his arms.

In contrast, the illumination effect of fluorite is superior.

"Luminous stone?"

Looking at the fluorescent stone in Lin Luo's hand, Wu's face suddenly showed a surprised expression.

"This isn't a glow-in-the-dark stone, it's a glowstone we traded from the Firefly Tribe. ”

Lin Luo shook his head and took out the other fluorescent stone he was carrying.

"If you like it, I'll give it to you. ”

For the tribal alliance, fluorite is no longer a precious thing.

"Good. ”

In this regard, Wu did not refuse, and directly reached out to take it.

After that, he looked up and down at the glowstone, nodded and praised: "It's really good, this glowstone is much stronger than the luminous stone." ”

"What kind of plant is that in your hands? It still glows. ”

Lin Luo asked Wu with a curious face.

"You'll find out in a minute. ”

Hearing this, Wu didn't make an explanation, just smiled and sold a pass.

After that, the team continued to set off, heading deeper into the Flame Cave.

There was not only one passage in the Yan Cave, and as they continued to go deeper, there were many forks in the road in front of them.

However, Wu seems to be very familiar with this place, and there is no hesitation in the choice of road.

Soon, the team was marching all the way down for more than an hour.

It's at least 500 meters deep, isn't it?

Lin Luo wiped the beads of sweat on his forehead with the back of his hand, and couldn't help but think secretly with some concern.

At this moment, he felt that the temperature around him had reached more than 80°C.

In such a hot environment, ordinary people can only last less than an hour.

Although they are also flesh-and-blood warriors with the lowest strength, their physical qualities in all aspects are far beyond ordinary people, and they took spiritual liquid before entering the Yan Cave.

But in the case of a fierce battle, it can only last seven or eight hours at most.

"Stop!"

And just as Lin Luo was about to ask Wu, Wu took the first step to stop the team.

Arrived at your destination?

Hearing Wu's words, Lin Luo immediately looked ahead.

I found that not far ahead, the originally narrow passage became wider.

It's just that it's covered in a gray, mist-like gas, and you can't see anything.

"The time hasn't come yet, let's find a place to rest first!"

Looking at the gray fog in front of him, Wu said loudly.

"Yes. ”

Hearing this, everyone nodded in response.

"Is there danger ahead?"

Lin Luo turned his head and asked.

"That gray mist is poisonous, and if you rush in, even a skeletal warrior will die. ”

Wu explained to him, "So, we have to wait for the gray fog to clear before we can move on. ”

Is it toxic?

Hearing this, Lin Luo looked at the gray mist in front of him.

It is not a toxic gas such as miasma, and it is impossible to form a miasma in such a high temperature environment.

Carbon dioxide, hydrogen sulfide, sulfur dioxide, methane?

Soon, Lin Luo's mind came up with several gases that would be released when a volcano erupted.

Although it is a dormant volcano, it is not surprising that there are gases inside that can poison and suffocate people.

Looking at Wu's performance along the way, it seems that he has been here more than once.

Therefore, Lin Luo didn't worry anymore, and followed the others to the wide place on the left fork in the road to prepare for a rest.

"Huh?"

And just as Lin Luo found a flat place and was about to sit down and rest, his eyes were suddenly attracted by a stone.

It was a red stone, and under the illumination of the fluorite, it looked crystal clear and very beautiful.

Ruby!

Lin Luo took the stone, put it in front of the fluorescent stone and examined it carefully, confirming that it was a ruby.

"You like this red stone?"

On the side, seeing Lin Luo's appearance of studying rubies, Wu opened his mouth and asked.

"I don't like it, I just think it's beautiful. ”

Lin Luo shook his head lightly.

"There are many beautiful stones here that you can take back with you and the women love it all. ”

Wu said with a chuckle.

"That's right. ”

A flesh-and-blood warrior of the Banyan tribe immediately nodded and said, "You see that this green stone is also very beautiful, and it is very popular with women in our tribe. ”

As he spoke, the flesh warrior showed Lin Luo a green gem the size of a pigeon's egg.

Emerald!

Lin Luo recognized it at a glance as an emerald.

"I'm not bad on this gem either. ”

Another flesh warrior showed a gem and said, "When you get outside, it will look even more beautiful in the sun." ”

Diamonds, diamonds?

Looking at the crystal clear and flawless gem, Lin Luo was a little unsure whether it was a diamond or a crystal.

Then he remembered that when a volcano erupts, it will bring gems such as rubies, diamonds, feldspar, and crystals to the surface.

So, it's obviously a normal thing to find a lot of gems here.

If this was on Earth, Lin Luo would definitely be crazy at the moment.

With so many precious gems, that's the rhythm of getting rich!

Unfortunately, these gems are only of some ornamental value here.

However, a thought immediately appeared in Lin Luo's mind.

Find a diamond for Mei!

He remembered that he had told Mei that if he could find a diamond mine, he would make a diamond ring for her.

Originally, he was just talking, and he didn't have any hope at all.

But I didn't expect that now there is really a chance to achieve it.

Without wasting time, Lin Luo quickly got up and began to look around with the light of the glowing stone.

It took him more than ten minutes before he used a dagger to dig out a rough diamond in good condition from the cave wall.

The shape of this rough stone is oval and looks crystal clear without the slightest impurities.

However, there is no way to compare it to the cut diamonds on a real diamond ring.

Pure natural rough diamond, the appearance looks more like glass.

However, Lin Luo was already satisfied.

Subsequently, when Lin Luo was about to continue looking for a few more gems and bring them back to Xiao Xi as a toy, his eyes were suddenly attracted by a touch of yellow.

"Step, step ......"

Lin Luo directly ran over in three steps and two steps, squatted down and broke hard.

"Click!"

Suddenly, a pale yellow stone was torn off.

Then, take the yellowish stone to your nose and sniff it gently.

Feeling the obvious stench in his nose, Lin Luo's face suddenly showed an expression of excitement.

Brimstone!

He was instantly sure that the pale yellow stones were sulfur.
