"Whew, Whew......"

Perceiving the increasingly rich spiritual power in front of him, Lin Luo immediately quickened his pace.

But at the same time, he was gasping for air, and his breathing became even more rapid.

Due to the lack of oxygen, Lin Luo not only felt shortness of breath at this moment, but also had some symptoms of chest tightness and palpitations.

"Lin Luo, are you okay? If not, you can go out first. ”

The Mole Spirit on the side quickly discovered Lin Luo's abnormality and asked him in a loud voice.

"It's okay, I'm still holding up. ”

Hearing this, Lin Luo shook his head slightly.

Although he was feeling very uncomfortable now due to the lack of oxygen, the spirit stone vein was close at hand, how could he just give it up.

However, at the moment, he was very envious of the Mole Spirit, which was able to fully adapt to this low-oxygen environment.

For the mole spirit, which lives underground all year round, a deep cave environment like this with low oxygen obviously does not have any effect on it.

Soon, not long after continuing to move forward, with the help of the glow emitted by the glowstone, Lin Luo saw some dead branches and leaves appear on the ground in front of him.

It's here?!

Seeing this scene, a smile suddenly appeared on Lin Luo's face.

Immediately, he immediately quickened his pace and saw that there was indeed a large cave in front of him.

On the floor of the cave, there are some dead branches and leaves, as well as the bones of many animals.

Obviously, this is where the earth-armored beasts sleep.

And here, Lin Luo sensed a very strong spiritual power.

You don't have to guess to know that there must be some spirit stones buried here.

"Lin Luo, you take a rest, I'll come to find the spirit stone. ”

At this time, the mole spirit turned his head towards Lin Luo and said.

"Good. ”

Hearing this, Lin Luo nodded and did not refuse.

Now in this lack of oxygen, he can't do too strenuous exercise.

At the same time, the Mole Spirit has a more acute perception of spirit stones than him, and is also an expert in digging.

Leaving the matter of finding the spirit stone to the mole spirit can be regarded as a specialization in the art industry.

And while the mole spirit was looking for the spirit stone in the cave, Lin Luo also took the glow stone to observe the surrounding environment.

It soon became clear that there was a tunnel on the other side of the cave.

Lin Luo took a look at it with a fluorescent stone and found that it was pitch black in front of him, obviously with a deep distance.

The front should be the way to the spirit stone vein!

Looking at the dark tunnel in front of him, Lin Luo secretly thought in his heart.

Although there was a vein of spirit stone here, the amount of spirit stone deposits would definitely not be as rich as the metal ore they had found before.

Thousands of catties of ore can be mined casually every day.

Otherwise, the Earth Armor Beast would have broken through to become the Beast King with a large number of spirit stones!

Such a rich deposit of spirit stone can only be found in the border wilderness.

In such a dense forest, the underground spiritual stone deposits are very limited, and it takes a long time to excavate a spiritual stone.

And at this moment, looking at the dark mine cave deeper in front of him, Lin Luo couldn't help but start thinking about the matter of digging spirit stones in the future.

Before this, Lin Luo had never imagined that the spirit stone veins would be so deep.

In this low-oxygen environment, it is impossible for even a powerful totem warrior to carry out heavy excavation work for a long time.

Not to mention, ordinary miners.

If ordinary miners were sent over like the metal and salt mines in the past, there would be a high mortality rate.

At the same time, the excavation efficiency will be very low.

Thinking of this, Lin Luo immediately turned his head to look at the mole spirit not far away, looking for the spirit stone.

Now it seems that handing over the mining spirit stone mine to the Mole Clan is the best option.

The Mole Clan's mole war pets are fully adapted to the environment deep underground, and are also very good at digging.

Giving them the Spirit Stone Mine to dig is much more efficient than that of the Totem Warriors.

"The spirit stones have all been found. ”

At that moment, the voice of the mole spirit rang out.

Soon, all the spirit stones have been found.

Lin Luo went over to check it, and the number was not very much, only six pieces.

This is not surprising, after all, spirit stones are not food for the winter, and it is impossible for earth armor beasts to store them in large quantities.

After most of the spirit stones were dug out, they were directly devoured by the Earth Armor Beast.

"Let's go, continue to the front and take a look at the situation of the spirit stone vein. ”

Lin Luo quickly put away the six spirit stones and stretched out his hand to point to the cave leading to the spirit stone vein in front.

"Good. ”

Hearing this, Mole Spirit nodded.

Soon set off again, walking deeper along the tunnel.

This time, they walked a long distance before they finally reached the end of the cave.

It can be seen that the ground here is covered with large pieces of rubble, which are obviously produced by the earth armor beast digging the spirit stone before.

"Mole Spirit, let's dig and see!"

Although his physical condition was not very good now, Lin Luo looked at the cave walls around him and said to the mole spirit with excitement on his face.

Excavating the most precious spirit stone, Lin Luo was naturally full of expectations for this.

Originally, Mole Spirit still persuaded Lin Luo.

However, looking at his eager look, he had no choice but to nod and say, "Okay!"

After speaking, he turned his head and glanced around, and quickly raised his front paw and pointed to the right cave wall and said, "The aura there is stronger, just dig from there!"

"Good!"

Hearing this, Lin Luo nodded in reply.

After that, he grasped the shaft of the purple bamboo spear in his hand and walked over to dig it.

The Molespirit was also quick to walk over, digging quickly with its front paws.

Five minutes!

Ten minutes!

Thirty minutes!

An hour!

Two hours!

......

In their excavations, time flew by.

And as time went by, Lin Luo's mood also had the original excitement, and gradually turned into depression.

Because, after more than two hours of digging, he and the mole spirit found nothing.

Except for the rocks, not even a single gem was dug up, let alone a spirit stone!

At the same time, heavy physical labor in this low-oxygen environment also made Lin Luo's hypoxia more serious.

At this moment, symptoms of dizziness and nausea have already begun to appear.

Sure enough, the spirit stone is not so easy to dig!

Lin Luo wiped the sweat from his forehead, his face was full of depression, and he sighed in his heart with shortness of breath.

He had already expected that the output of excavating spirit stones would definitely not be very high.

But I didn't expect it to be so low.

This made Lin Luo wonder if he could dig up a spirit stone in a whole day.

Although he thought so in his heart, the movements of Lin Luo's hands did not stop.

With his current situation, he can still hold out for about half an hour.

If he still doesn't get anything by then, then he can only leave with regrets.

"Lin Luo, forget it!"

On the side, the mole spirit said to Lin Luo worriedly.

"It's okay, I can hold on a little longer. ”

Lin Luo shook his head slightly.

"Ding!"

As soon as the words fell, as the rock in front of him cracked under the heavy blow of the purple bamboo spear, a touch of crystal clear emerald green came into Lin Luo's eyes.
