From above, these caves are densely packed, like spider webs, very small and bottomless.

When I came to the mines, I realized that each mine was very large, comparable to a house, and it was pitch black inside, very deep, and I didn't know where it led.

"How many years has this spirit stone mine been mined?"

Lin Feng asked.

"It's been thirty-one years."

Fang Yuande replied.

"Thirty-one years?"

Lin Feng was slightly stunned, this time was much longer than he thought.

Before, he thought that it would be at least ten years, but now it seems that he still far underestimated this spirit stone mine.

"When did the Rock Beasts first appear?"

Lin Feng asked curiously.

"About half a year ago."

"Have you been okay before?"

"Yes, it was always safe and sound, but it wasn't until half a year ago that mysterious ores were dug up in this mine, and rock beasts began to appear."

"Mysterious ore? What kind of ore? ”

Lin Feng asked curiously.

"I'm sorry, Lord Messenger, since the domain master didn't tell you, it's inconvenient to tell you about this matter later, if you want to know, you should ask the domain master directly."

Fang Yuande looked embarrassed.

Lin Feng didn't embarrass him, and didn't continue to ask, but just made a note of this matter in his heart.

The appearance of rock beasts is mostly directly related to mysterious ores.

It's just that the Lord of the Ruins Domain didn't tell him directly, obviously because he didn't want him to know.

Let's take a look first, if you really can't suppress the rock beast, then you can only go back and ask the Lord of the Ruins Domain to start with the mysterious ore.

"Envoy, we can only send you here, and there will be rock beasts inside, and we don't dare to go in."

Fang Yuande stopped and said embarrassedly.

The same goes for others.

"Alright, you guys go back."

Lin Feng waved his hand, not expecting any help from these people at all.

After all, if these people could deal with the rock beasts, the Lord of the Ruins Domain would not have sent him here to do so.

"The envoy should pay attention to safety, and I hope that the envoy will return in triumph."

Fang Yuande said with a fist at Lin Feng.

After that, take all the deacons and leave quickly.

In the entire pitch-black mine, only Lin Feng was left.

A sense of tranquility arises spontaneously.

The faint of heart would not dare to stay here, let alone go deeper.

However, for Lin Feng, it had no effect.

Under the sense of Haoran's righteousness, the darkness seemed to be non-existent, and everything in the mine was hidden.

It's just a little strange, Lin Feng's Haoran Righteous Qi can sense three thousand five hundred meters away, but it can't completely cover this mine.

It wasn't that the depth of the mine cave was more than 3,500 meters, but that there was a strange force that was stopping Lin Feng's induction.

"There must be a unique power in this!"

Lin Feng became more and more sure.

First, it can produce mysterious ores.

Second, a powerful rock beast was born.

Third, there is a mysterious force to prevent Haoran from sensing righteousness.

These three points indicate that there is a unique power in this.

Lin Feng continued to go deeper.

The mine continued to extend downward, and when Lin Feng felt that he had come to a place two thousand miles underground, a rock beast blocked Lin Feng's way.

It was a strange creature, looking like a dog, but it was covered in rocks, hairless, even a pair of eyes made of rocks, and its teeth were sharp, emitting a cold light.

Its tail is even more exaggerated, not only made of rocks, but also has countless barbs, if it is pumped, I am afraid that half of its life will be confessed here.

"Earth Immortal Early Stage Cultivation!"

Lin Feng's expression was solemn, and he didn't dare to be careless.

This kind of creature that can give even a strong person of the level of the Guiru Domain Lord a headache should not be underestimated.

"Roar"

There was a loud roar that almost knocked the entire mine down.

The four legs of the rock beast suddenly exerted force, directly turning into a gray light, and came straight towards Lin Feng.

"What a speed!"

Lin Feng's face changed slightly, and he immediately showed his words, constantly changing his position.

However, the rock beast is like a shadow, and it can't be shaken off at all.

"Cut in half!"

Lin Feng drank lowly.

A sword light wrapped around the rock beast's waist and quickly spun around.

"Rustle"

The sword qi seemed to be slashed on top of a powerful magic weapon, and it was actually full of sparks.

If you take a closer look, the blow that can kill the early stage of the Earth Immortal is actually only leaving a faint trace on the waist of the rock beast.

And this trace is still disappearing rapidly.

"There is a strong force in the mine, helping the rock beast recover quickly!"

Lin Feng immediately made a judgment.

No wonder it's so difficult that it simply can't be killed.

Unless you directly blast the rock beast to pieces.

"Roar!"

The rock beast attacked Lin Feng again.

This time, its speed was even faster, even if Lin Feng's speed was so fast that it was comparable to an instantaneous movement, it was still quickly shortened by it.

"Bang"

The tail of the rock beast suddenly slammed towards Lin Feng.

The speed was so fast that the air was directly blasted, and a sonic boom was heard.

At this moment, a layer of cold sweat broke out directly from Lin Feng's back.

You must know that this is not the Holy Spirit Continent, but the Zhou Tian World.

The space of the Zhou Tian World was ten million times stronger than that of the Holy Spirit Continent, and Lin Feng could easily tear apart the space of the Holy Spirit Continent, but he could not shake the space of the Zhou Tian World in the slightest.

However, the tail of this rock beast actually produced a sonic boom, which is a bit terrifying.

"Soul Killing Needle!"

Lin Feng did not hesitate to unleash the strongest blow.

Soul Slayer stabbed the rock beast in the head.

However, the Rock Beast didn't seem to react at all, as if the Soul Slayer had no effect on it, and was completely ineffective.

"Sure enough!"

Lin Feng had no choice but to sacrifice five swift poems, and suddenly accelerated to avoid this blow.

"Boom"

A muffled sound rang out.

The tail of the rock beast is pumped against the stone wall.

The entire mine was trembling violently, and a ray of light lit up, it was the magic circle that supported the mine, and at this moment, it was directly torn open by the tail of the rock beast.

"Roar!"

Another roar.

It wasn't from the rock beast in front of you, it came from the depths of the mine.

"There's one more!"

Lin Feng's pupils contracted and he quickly retreated.

Just now, Fang Yuande said that only one rock beast would appear at a time.

Now, it seems, things have changed, and a second rock beast has appeared in the mine.

I don't know if there will be a third rock beast.

The rock beasts have always been so difficult to deal with, Lin Feng is by no means the opponent of the two rock beasts, he must leave as soon as possible and then find a way.

"Roar"

The rock beast in front of him saw that Lin Feng wanted to escape, and immediately pursued him.

Fortunately, Lin Feng had the blessing of the swift poem, so he avoided the mouth of the rock beast and escaped.

"This thing shouldn't be chased all the way out, right?"

Lin Feng was a little worried.

It wasn't until it was only about five hundred meters away from the ground that the rock beast chasing Lin Feng stopped its tracks, let out a few roars unwillingly, and disappeared into the depths of darkness.

"It's terrible!"

Lin Feng let out a sigh of relief and flew outside.

Seeing Lin Feng come out safe and sound, Fang Yuande and the others all showed shocked expressions.

Hearing the roar of the rock beasts coming from inside the cave, they thought that Lin Feng was dead.

Unexpectedly, Lin Feng came out alive and unharmed, which was completely beyond their expectations.
