Two days later, news came from the Spirit Mine in the Northern Region of the Immortal Courtyard.

Several strong people sent to investigate the spiritual stone mine disaster were all dead, and none of them survived, and this incident also alarmed many other forces, all of whom felt that the spiritual mine of the Immortal Courtyard might have something unbelievable, and they were all ready to move.

However, before the matter was clarified, they still did not make a move, they were all waiting and waiting, waiting for how the Immortal Yuan would deal with this matter!

"Send someone to investigate immediately, and find out what happened in the mining area no matter what!" The old fox couldn't sit still.

The top management of the academy held a small meeting, and finally decided to select a few top disciples from Law Enforcement Elder Blue Eagle Fei to go to the Northern Regions Spirit Stone Mine to see what was going on.

Of course, in order to ensure the safety of the academy's disciples, they are just bystanders, and if they don't personally participate in the investigation, the academy will send other masters.

Soon, the list of people going to the Northern Regions Spirit Stone Mine was decided, and among them was Ye Fan.

On the one hand, Ye Fan's recent performance is too dazzling, and Lao Immortal wants him to learn more.

More importantly, Ye Fan learned the trick of finding the dragon, which can help investigate the problem of the spiritual mine - in the mining area, the dragon-seeking recipe has the effect of seeking good fortune and avoiding evil, and there is also a superior means of finding the spiritual stone vein, which is exactly what is most needed to investigate the catastrophe in the mining area.

The next day, Ye Fan, Shi Ye, Qi Tianlin, Wu Jingtian and others were summoned to a forbidden place in the academy.

Ye Fan and the others were no strangers to the forbidden land, it was the hall that crossed the void to the secret realm of immortals.

There are various teleportation arrays in the main hall, which can cross to any place in the Five Domains, and it is the top secret place of the Immortal Temple.

Rumble!

Under the leadership of Lan Yingfei, Ye Fan and his party boarded the teleportation array platform, the domain gate opened, and everyone stepped into the domain gate.

There was silence in the spatial passage, no time passed, no brilliance emerged, and in a dark void, it was exceptionally silent.

As if in a hurry, it seems like ten lives and ten lifetimes, this strange journey is finally over, making people feel the flow of time.

The void cracked, and Ye Fan and the others stepped out of the void and descended on the bitter cold land of the Northern Regions.

"Is this the Northlands?"

Ye Fan looked around, although he had already crossed to the Central Domain before, but the Central Domain was not the Northern Domain after all, this was a place rich in spirit stones.

As far as the eye can see, the surroundings are desolate, with no flowers, no bustling crowds, and no vibrant vegetation. The land was desolate, red soil, reddish-brown rocks, desolate and desolate.

The vast expanse of the earth, utterly empty, with no signs of life, only a few bare stone mountains dotted on the horizon. It's a barren land, with no life, no people in sight, and it's lifeless.

"That's right, this is the Northern Regions, and it is also the main production area of our Immortal Courtyard's spirit stones, most of the spirit stones you receive in the Immortal Courtyard every month are produced here!" Blue Eagle Fei nodded.

"The environment here is really harsh, far worse than my hometown!" Ishino muttered.

"You can be content, the Northern Regions are like this!"

Han Sandong was born in the Northern Regions and knew the environment of the Northern Regions very well, but when he came here, he was as if he had returned home, and he was very familiar.

"What if you are not satisfied? We're not going to be here for long anyway, it's just a trip. Ishino quickly adjusted his mood and looked around curiously.

"Tsk...... It's a place where birds don't! ”

Even the Qi demon, who has always been unsmiling, said this, which shows how bad the environment here is.

The northern region is boundless, and the spirit stone mines are all over the world.

Compared to the vast expanse of land, it can be called sparsely populated, with no people for thousands of miles, and most places are deserted.

As the so-called success is also a spirit stone, defeat is also a spirit stone, this mysterious substance condenses the essence of heaven and earth vitality, and seems to suck the entire northern region of heaven and earth vitality dry.

The four words of outstanding people and spirits really have any intersection with the Northern Regions. Although there are oases in the North, they are insignificant compared to his vast territory.

There are abundant spirit stones here, and people will not worry about food and clothing, but it is precisely because of spirit stones that there are often fights, and the people are in a hurry, and they often fight for the spirit stone mines.

Therefore, most of the source mines excavated by the major holy lands, imperial clans, and supreme sects in the Northern Regions were brought over from their respective regions.

The preciousness of the spirit stone is to the monks, like gold coins to mortals, causing bandits to run rampant here, not only the locals, but also the forces from all over the Eastern Wilderness.

In order to compete for the spirit stone mine, there is a big fight, and the blood is flowing like a river, which is the most common thing. Overall, the Northern Regions are a mess. This barren land, famous all over the world for its spirit stone mines, is destined to be chaotic and bloody.

Just when everyone was talking, Blue Eagle Fei walked forward on foot, leaving a series of footprints on the red earth, and there were gusts of wind and thunder, and suddenly his figure disappeared in front of him.

"Boom ......"

The earth shook, the mountains and rivers seemed to move, thousands of people stood unsteadily, and many fell to the ground, all showing signs of panic.

Ahead, the scenery changed greatly, and there were many stone houses piled up with mountains and rocks on the empty land, and some figures appeared, as well as spiritual stone mines.

This area is covered with a peerless array, which hooks the power of heaven and earth to protect the mining area of the Immortal Courtyard, and envelops everything inside!

In the northern region, there are endless mining areas, but when it comes to the multi-production areas, it is the area around the primitive ancient mines, with it as the center, a radius of 100,000 miles, which is equally divided by the major holy places.

The primordial ancient mine, one of the several forbidden areas of life in the Xuan Realm, is in the deepest part of this area, surrounded by the mining areas of the major holy lands, but no big force dares to explore.

The Spirit Stone Mine of the Immortal Courtyard is located in this vast area, and compared to the spirit stone mines of other holy places and the Imperial Clan, which are often looted, the Spirit Stone Mines of the Immortal Courtyard and the Imperial Courtyard are much safer.

The Immortal Courtyard Spirit Stone Mine, like the Imperial Courtyard, is close to the primitive ancient mining area, and the spirit stones produced here are of extremely high quality, and the many strange stones are produced, which are contaminated with a primitive breath and are extremely precious.

Of course, in order to ensure the safety of the mining area, Xianyuan is also a top master in the mining area, and his strength is not much different from that of strong people like Lan Yingfei and Zhao Guangsheng.

At this moment, he was looking worriedly at the No. 7 mine in the distance, just near the mine, the gray fog was filled, and there were dead bodies everywhere, which was shocking.

As the person in charge of the mining area, he naturally didn't dare to hide such a big thing, and immediately reported it to the fairy house.

However,

The first batch of immortal masters who rushed here never came out after going down to the mine, and obviously they had suffered an accident!

Ye Fan and the others were the second wave, and soon, with the blue eagle flying, they met the person in charge of the mining area, and under the leadership of the person in charge, they saw the No. 7 mine where the accident occurred!

At first glance, when they saw the situation outside the mine, Ye Fan and the others were startled by the scene in front of them, near the mine where the accident occurred, there were fifty or sixty corpses lying horizontally, all of them with dark faces and wide eyes, as if they were dead.

In that mine, wisps of black fog overflowed, and a sense of oppression could still be felt far away, and it was these black fogs that caused this tragedy.

"Why don't you bury the body?" Lan Yingfei didn't look back, looked near the mine and asked.

"No one dares to approach, there is something deadly in that black mist, and even if I get close, my life is in danger, so ......," the person in charge replied with a deep groan.

"Have all the pensions been paid?"

"It's all gone, Eagle, we've lost too much this time, I suspect something ominous will happen, this disaster is completely different from other mines." The person in charge was worried.

"Well, I'll go and see what's going on!" Blue Eagle Fei said, walking towards the mine step by step, ignoring the black fog that permeated the air.

"Eagle beware!"

The person in charge couldn't help but remind him, he had personally learned the power of those black fogs, even he was almost melted by the black fog, and he was very powerful.

"Hmm."

As he spoke, Blue Eagle Fei had already reached the edge of the black mist, emitting a faint light all over his body, blocking the black mist from his body, making it unable to invade his body.

Ye Fan and the others also approached those black fogs, but none of them came into contact with those black fogs, and when they were still a hundred meters away from the black fog, they all felt a great danger.

"Are there any survivors?"

Ye Fan frowned and asked the person in charge of the mining area.

"No, when I was born, everyone died, even the people who were guarding the mine to transport ore!" The person in charge shook his head, and there was deep worry in his tiger eyes.

"The black fog has faded!"

Ye Fan looked carefully, and sure enough, that black mist was gradually dissipating, and it seemed that it was not far from the danger being lifted.

Blue Eagle Fei only went deeper than ten meters into the black fog area and stopped moving forward, because he also felt a huge danger, and those black fogs were filled with a terrifying aura of death, which made his divine power consumption four or five times faster than usual, which was not a good phenomenon.

Fortunately, the black fog is slowly fading, and it may not be long before the black fog will completely dissipate, and it will not be too late to explore by then.

"I'm going to see what the black mist is!"

An academy powerhouse who came with Ye Fan and the others sacrificed a white jade bottle and tried to collect a wisp of black mist for research.

"Huh!"

The white jade bottle turned into a streamer of light and flew forward, and soon emitted a soft halo and began to absorb the black mist.

"Click!"

Something surprising happened, as soon as a wisp of black mist submerged, the white jade bottle shattered, dimmed, and fell to the ground.

"This ......"

The strong man's body shook, and he looked at the broken white jade bottle with an incredulous expression, that was his spiritual treasure! It was ruined like this, and it couldn't contain a wisp of black mist.

"The spiritual treasure cultivated by the cultivators in the early stage of the Venerable Realm can't block a wisp of black mist, what is it?" Everyone was taken aback.

"Pre-primeval ......"

Ye Fan's eyes shot out two strange lights, and from the black mist, he actually saw the phantom of a humanoid creature appearing, although it was very vague, but he was sure that he was not mistaken.

"Could it be that these black fogs are related to pre-primeval humanoids?"

Ye Fan was not calm, he already understood the horror of humanoid creatures, if a living humanoid creature was dug up under the mine, it would definitely be a catastrophe!
