The black fog has been in full swing for many days. At the beginning, the black fog was much thicker than it is now. Most of the miners in the Immortal Academy died at that time.

If the person in charge had not appeared in time and took the remaining miners away with the mysterious skills, it would probably be that there would be few people left in the entire mining area.

At this moment, the miners who survived by chance were trembling in the distance, with endless fear in their eyes. They didn't even know what was happening in the mine. They only saw the black fog spreading, and the brothers around them fell one by one.

That miserable death made ordinary people feel infinite fear, and for the first time, he felt that death was so close to him.

Fortunately, the black fog is gradually dissipating and fading, which makes their fearful hearts calm down a little.

In addition, the Immortal Courtyard does not regard them as ants like other holy places or imperial clans. At least, they will also consider ordinary miners.

Looking at everything in front of them, the middle-aged strong men in the Immortal Academy all showed a solemn look. They all felt that this time the matter was a bit extraordinary and they had no idea.

Three hours passed before the black fog completely dissipated and disappeared into the world.

Not long after, a yellow dog was thrown into the mine, causing constant barking of dogs. Although it was a bit miserable, there was no doubt that it was not dead.

After a long time, the barking of dogs did not stop. Only then did the strong men in the Immortal Court breathe a sigh of relief. It seemed that there was no danger in the mine.

"Fortunately, it's not as bad as I thought!"

"It seems that it is just a vicious aura, and no living creature appears, otherwise it would have been dead silence here."

Lan Yingfei brought several middle-aged strong men from the students, Ye Fan and others to the wellhead, observed each corpse, and then leaned down for a while, but no abnormalities occurred. "These corpses were carried away and they were buried in a waste mine."

Lan Yingfei sighed, and then instructed Ye Fan and others to bury the bodies. They are monks and can be discovered and avoided in time even if there is any danger. However, these people died in a very miserable way, and it is difficult to guarantee that they will not have any poison. Once ordinary people come into contact with these, they may die.

If the Immortal Court is convinced by kindness, it will naturally not ruin the lives of these ordinary miners in vain. This is the completely different place between the Immortal Court and the Imperial Court and other holy places.

Even if mining encounters various dangers, the Immortal Court never has to worry about not having miners to use, while other forces need to hire at high prices, and even use unconventional means to catch some ordinary people to mine.

In addition, even the mining areas of the imperial clan are often robbed by nine bandits, only the Immortal Academy and the Imperial Academy, which never visits the nine bandits, which also ensures the safety of ordinary miners' lives.

Soon, the corpses outside the wellhead were cleaned up, and the next ones were the corpses in the mine. Fortunately, Ye Fan and others had space spiritual weapons, so they just needed to put these corpses into the space spiritual weapons and then take them out, which was not a danger.

"Be careful about everything. If there is an emergency, don't worry about anything. Just escape first, do you know?"

Lan Ying flew to Ye Fan and others and gave a message, then watched them go down into the mine.

The mine was dark, but fortunately everyone had already reached the state of whitening in the empty room. As long as it was not absolutely dark, the vision was still unaffected. Looking around, there were corpses on the ground, with all kinds of deaths, and extremely tragic.

"hiss……"

Even though everyone was used to death, the scene in front of them still made them gasp, and there were too many corpses.

Qi Tianlin, Shi Ye, Hu Bi and others each sacrificed their own space spirit weapons and took the corpses on the ground.

Ye Fan also sacrificed a jade bottle and activated the mysterious skill. The jade bottle emitted a huge suction force and took the corpse on the ground in.

While cleaning up, everyone moved in. The more they went in, the more corpses there were, and the more mortal death was even more shocking. Some corpses had completely turned into piles of dead bones, and even the bones were black, and they were obviously poisoned and died of death.

The deeper he went, the more uneasy Ye Fan felt, as if there was a huge danger waiting ahead. This feeling made him feel very uncomfortable.

Um?

Suddenly, Ye Fan found a light coming from the front. When he looked closely, he found that it was a heavenly spirit stone the size of a human head, shining and shining, embedded in the stone.

Ordinary spirit stones are colorful, with a dull color and contain very little energy of heaven and earth. Although they are much richer than the energy of heaven and earth in the world, their value is not high.

The medium-grade spirit stone is seven colors with a faint light. Under the same volume, a medium-grade spirit stone contains the essence of heaven and earth that is much higher than that of ordinary spirit stones.

The top-grade spirit stones are nine colors, brightly radiant and very high value. Generally speaking, only forces like the holy land and supreme sects, imperial clans, can have them. It is already a great luck to be able to get a small sect like the Xuanwu Sect.

On the top, it is the best spirit stone, which is more precious than the best spirit stone.

The heavenly-grade spirit stones transcend the category of top-grade spirit stones, and it is not an exaggeration to describe them as priceless treasures.

A piece of heavenly spirit stone the size of a human head appeared in front of him. How could Ye Fan not be moved?

Not only him, but others also discovered it and quickly surrounded it. There was no corpse around this heavenly spirit stone. I don’t know if it was completely qin or no one died here at all.

"The problem lies here..."

Ye Fan walked carefully to the front, saw all this clearly, and took a breath of air conditioning.

There was a claw inside the sky-grade spirit stone with a large human head, which was close to the human palm, but it had very dark green scales. Each scale was as big as a fingernail, shining with green light, even the palm was no exception, and it looked particularly ferocious.

"Looking at the time when these stones were formed, they were at least creatures before the ancient times. Could it be that they were really human-shaped creatures?"

Ye Fan was surprised. He thought of the humanoid figures in the black fog he saw outside the mine.

"Ghost paw?"

"Who is the evil one?"

"What monster?"

Shi Ye, Hu Bandits, Qi Tianlin and others screamed in shock. This was the first time they saw such a thing and were particularly shocked.

Ye Fan rubbed the stone wall with his hands and penetrated his divine thoughts into the stone wall. He was shocked. He found that it was originally a huge stone, which was chiseled and cracked by the mining man, and this heavenly spirit stone appeared. There were bone patterns in the stone layer, which were connected to this spirit stone.

"this……"

Ye Fan was shocked.

This should be a fossil, but the palm was sealed by the spirit stone, and it was intact, and other parts became fossils.

"This should be the skeleton of a powerful demon clan, right?" asked the Hu bandit.
