"If I read it correctly, this should be the legendary essence of ghost energy. It is said that only in special places can ghost energy be nurtured. The essence of ghost energy is like something that can bring vitality to the ghost energy world. As long as there is the essence of ghost energy, the world will generally not be too bad."

The essence of ghost energy?

After hearing the ghost's explanation, Lin Fei's eyes lit up. Unexpectedly, this bead had such a background. Then, as the bead floated farther and farther away, Lin Fei quickly followed the ghosts.

But unexpectedly, after a distance, they actually came to the crack in the underground again...

This time, even Lin Fei was surprised.

From the ghost energy passage at the bottom of Cuizhu Mountain, you can actually go directly to the cracks underground?

No wonder the teleportation formation was placed on Cuizhu Peak and was able to send ghosts to this place. It turned out that it was not teleported away, but was pushed to this place by the rich ghost energy...

"No wonder, I said, how could the underground crack change be so big..." Lin Fei said to himself.

At first, he couldn't figure out why life was derived from the underground crack. Now, seeing the essence of ghost energy, all this suddenly became clear. It was the essence of ghost energy that brought vitality to the underground crack...

Now that there is a ghost energy essence in the crack underground, the crack will definitely develop better and better. At that time, the ghost energy here may also be changed and used for everyone to practice.

At this moment, Lin Fei decided not to disturb the crack underground. Since it has been confirmed that the ghost energy essence has appeared here, and the ghost energy essence does not harm the ghosts, there is no need to worry about this place.

Just wait patiently for the cracks to develop underground.

As Lin Fei thought, in just half a month later, ghosts came to report. They found that all the ghosts transformed from ghost energy in the underground ruins disappeared, replaced by an original ghost energy. This ghost energy is several times better than the ghost energy that ghosts come to practice on weekdays.

Moreover, this is not a little bit of ghost energy, but in the entire crack underground, there is such ghost energy. With so much ghost energy, if you practice it for the ghosts below, you may not be able to use it for several months...

At the same time, as long as the essence of ghost energy always exists in this underground crack, the underground crack will still develop, and the ghost energy here will become stronger and stronger. In the end, it will definitely become a very rare treasure land.

Lin Fei knew that this was a rare opportunity, so he immediately arranged for ghosts to go in and practice. Now there is no threat from underground ghosts, even if these ghosts go down, they will not encounter any danger.

A large number of ghosts went down to practice, and with the assistance of the majestic and pure ghost energy, the strength of these ghosts increased very quickly.

Everyone goes on in batches, and every time they go down, they can get a chance to change their appearance. In just three days, the Guiming clan members have been renewed, and their overall strength can be said to have completely doubled...

This almost perverted improvement will naturally attract the attention of other ghost tribes. As the saying goes, there is no airtight wall in the world. The underground crack found in this city quickly attracted the attention of these ghost tribes.

Although everyone knows that the Ghost Nether Clan is no longer the fish that was used to be bullied by everyone, but now seeing that the Ghost Nether Clan is empty in a treasure house that can be cultivated by everyone, other Ghost Clan are also jealous.

Among them is Teng Xue of the Si Demon Clan. Teng Xue is the leader of the Si Demon Clan. Last time, in order to compete for the demon cauldron with Lin Fei, Feng Qingyun finally left, but in fact, he has been inquiring about information related to Lin Fei during this period.

Now, when we know that Lin Fei has found another cultivation treasure for the Ghost Nether Clan, Teng Xue naturally can't watch it...

The ghost clan and the ghost clan have always been competing for resources. Now that the Ghost Clan has gained such great benefits, who doesn’t want to get a share of the pie, let alone the blood that has already had a conflict with Lin Fei.

He is now studying it, now looking for Lin Fei, and then snatch the treasure land of the Ghost Nether Clan for him...

While Tengxue was still studying specific plans, Lin Fei's city was also in trouble...

In recent days, the Ghost and Nether Clan have been practicing in underground ruins, and Lin Fei has not been too concerned about it. He just doesn’t need to worry about this little thing. It’s like in the academy, the academy opened up various cultivation environments for the students, and then left it to the students to practice on their own.

Lin Fei also followed this pattern and left the bottom alone.

But unexpectedly, just as everyone was practicing underground, suddenly, a shocking roar came from the underground ruins.

However, at this moment, a loud roar suddenly appeared in the sky, and violent fluctuations appeared in the void. The sky seemed to have changed shape in this squeeze.

"That's it?" Countless people's faces changed by this inexplicable movement. Then, a ghost jumped up step by step. After only one glance in the direction of the movement, he was shocked. The aura that appeared was so strong that it made him temporarily deaf in his ears.

Just as he looked over there, the other ghosts also saw it. It was a black shadow beast. It was like an octopus, with countless tentacles growing under its feet. Its neck was covered with blood, as if it had just rushed out of a pool of blood. It opened its mouth, and its fangs in its mouth were as huge and hard as Optimus Prime. It seemed that it could poke a hole in the sky with one stretch.

The black shadow beast was extremely powerful, with black mist soaring into the sky, forming a tornado in the air, sweeping across the earth, and everything in the cracks under the ground was swept across and instantly turned into ruins.

Countless people were screaming shrillly, countless injured people, everyone was shocked, and they were silent.

What kind of monster is that?

Zhang De watched the monster in shock, his body trembled, and felt a chill in his back spine. At this moment, the black shadow beast in the void opened its fangs, and the black light formed a black mist as big as a mountain, rushing towards this side...

The earth was shaking, the mountains in the distance collapsed, and the black fog emitted aura of evil, as heavy as a mountain, making people breathless.

Many ghosts are chilling from their bones and run away for fear of death.

Behind them, the shadow monster's tentacles covered the sky and the sun, and thousands of tentacles moved together, feeling like the mountains collapsed and the earth was shaking. At this moment, the shadow monster also broke through the air, and the black fog surging like a sea, suppressing it from the void, directly sweeping through the underground ruins...

The black shadow beast opened its big mouth, its mouth basin was like a crescent bay, and black magma flowed inside, comparable to volcanic lava. The cone extends a black giant tail, with blood stains on its tail, red as red as iron, with a strong killing aura.

"That's it?" At this moment, Lin Fei also heard the movement and came to this underground ruins. When he saw the black shadow beast that was killing ghosts, Lin Fei's face changed slightly.

When did this monster run into the crack in the underground...

Could it be from ancient times?

The black shadow beast roared at this time, and it spitted clouds and mist, and black silks fell from the void, like water from the waterfall falling from the sky. The black silks covered ten miles of radius, and the range was astonishingly large, which made countless people terrified. In this range, many people died tragically, and their shrill screams rushed into the sky.

The black shadow beast probably noticed Lin Fei and stared at Lin Fei, as if the actual murderous intention turned into a black giant axe. Thunder flashed on the giant axe, and frost attached to it, freezing the strong wind.

Seeing that the attack was very powerful, Lin Fei dared not to shake it. This was definitely a monster with a strength of no less than his true body. He turned around and left. At this time, the black giant axe fell, and the blue sky seemed to have been cut down, cracking the ravines.

Lin Fei's quickness could only be used to fight with a sword energy.

A huge blue sword was shot into his eyes and then overturned the black giant axe. However, Lin Fei's body was also shocked, but Lin Fei had no time to check his body, so he just left back again.

On the opposite side, the huge body of the black shadow beast rushed around, shaking the earth. The black light shrouded on the black shadow beast was burning like a flame. It was like a volcano hitting Lin Fei.

Lin Fei jumped into the air and waved the sword shadow. His speed was extremely fast. He slashed from the forehead of the black shadow beast. When the two came into contact, they immediately emitted a thick spark, like a clang of steel clashing.

"The defense of this black shadow beast is amazing..." Lin Fei took a breath of cold air. However, the sword energy he had just used Taiyi sword energy, but he did not even cut the skin of the black shadow beast. His defense can be imagined.

The black shadow beast rushed over, and Lin Fei retreated back to the city at lightning. At this time, the beast also rushed out, and his target had obviously become Lin Fei.

Lin Fei's attack on him just angered him. At this moment, the giant beast looked at Lin Fei fiercely and spit out a black light. The black light had a strong toxicity. All the contacts turned into pus and blood, and they were terrifying in death. The ghosts nearby were shocked and only knew how to escape.

At this time, the black shadow beast used its body to shake the city, and countless buildings instantly turned into dust. The flying stones splashed like meteors, and hundreds of ghosts were immediately crushed to pieces, and they couldn't even run away.

Oh My God……

Everyone's eyes were wide open, and blood was clearly visible. It was the first time that many people saw such a fierce and vicious beast. They were scared by it and were frightened. They felt that their hearts were about to jump out.

And on the other side.

Thick smoke rose slowly from a high platform, and the white smoke never dissipated for a long time. This is a signal. The entire city is too huge. Even if there is a black shadow beast, everyone may not be able to pay attention. After igniting this signal, ghosts with a little strength will come here.

After all, this is a city, and it has been developed by Lin Fei for so long. After arriving in the city, Lin Fei immediately arranged for it. Not long after, ghost arrows shot out.

The dazzling bright lights were connected together, and the arrows shot by the guards in the city formed a large shiny net. The white light nets took off and all of them bombarded the dark shadow beast's lower abdomen.

However, what is surprising is that this did not cause any harm to it. The black shadow beast was driven by its physical strength, and its majestic body did not even show any scars.

Instead, it angered the giant beast.

The giant beast was furious, and thousands of tentacles were pressed into nothingness, and sharp black lights fell from the sky, like the toughest black needles in the world, blooming in the city like bamboo shoots after a rain.

Suddenly, another scream appeared...

Screams came one after another, a tall building collapsed, sand and stones were flying, and thick smoke rolled, and more than hundreds of victims pressed down on the ground.

The scarlet blood stained the earth red, and it was shocking to look at it.

"..." Lin Fei looked at it from a distance, his brows gradually frowned. He was a little confused. Since this black shadow beast lived in the underground ruins, everyone has been practicing there for a while. Why hasn't they encountered a sneak attack from the black shadow beast?

On the contrary, now, why is this black shadow beast suddenly going crazy...

However, when Lin Fei saw the dark shadow beast's lower abdomen, his expression moved. Then, without saying anything, he left Zhang De beside him and went back into the crack underground.

Soon, Lin Fei came to a huge cave in the cracks underground.

Continuously deepening into the cave, Lin Fei quickly discovered a deep pool.

The deep pool is shimmering and the lake is bright. There is a very strange fish with a pair of fleshy wings and fangs, which keeps harassing him.

However, Lin Fei opened a red arc circle and enveloped himself, and outside the circle was filled with sharp sword energy.

Keep the strange fish outside.

Lin Fei's spiritual sense spread and spread every place. He soon found an unusual place. He found a cave here. Lin Fei swam to the surface. The cave was in the corals and the entrance was narrow, so it could only accommodate a child.

But it's not impossible to go in...

A flash of light, Lin Fei squeezed in.

"That's..." Lin Fei widened his eyes. He saw that many forks suddenly appeared in the cave. The intersection stretched like earthworms, and there were countless amounts. The water source outside seemed to be isolated from an invisible light shield here, and it was like land, and there was no water seed.

The environment is dark and humid, and the air is filled with fishy smell. There is a cluster of purple flowers growing on the stone wall above the head, and a layer of bright light is flowing.

There is indeed a world inside...

Lin Fei stood at the intersection, with eight cave entrances in front of him. The cave entrance was gloomy, like the sequinous eyes of giant beasts, emitting a cold and cold light, making people shivering out of thin air.

Just as Lin Fei was considering which cave to go, the world suddenly became chaotic, and a huge vibration came from behind, like a volcano erupting. Lin Fei staggered and almost fell to the ground.
