The old demon of Black Mountain smiled indifferently and said, "I have never become a ghost, but I just continue to practice in the form of a ghost. Naturally, there is an essential difference from these ghosts."

"I have not lost any memory. It is no different from some practitioners on the level of wisdom. It is just that the form has changed. Then I communicate with you, otherwise ordinary ghosts will only find ways to kill you and devour your soul."

Wu Yi carefully observed the old monster in Black Mountain and found that he hid his body under the black robe. Its floating and floating indeed existed in the form of a ghost.

But he is indeed different from other ghosts. He does not emit too strong resentment. It can even be said that even the ghost energy is faint. If he saw this old monster in Black Mountain elsewhere, Wu Yi might not be able to discover his ghost identity.

The Black Mountain Old Demon was able to control his own energy well, which made his ghost energy not show, but his strength was much stronger than the ordinary ghost king. After all, these ghost kings were only using their own instincts, while the Black Mountain Old Demon was systematically practicing and fighting, and could grow faster than the ordinary ghost king.

On the black robe of the Black Mountain Old Demon, Wu Yi saw a ghost mark with black smoke spreading open with his mouth. The location of this mark was near his chest. This is where ordinary people sign the organization or sect logo. In other words, this Black Mountain Old Demon is likely to be a member of a powerful organization.

This made Wu Yi feel moved. It seemed that it was not a coincidence that these ghosts appeared here. The woman in red in Ji Wuxiang Sect might have contacted him.

So Wu Yi asked tentatively: "Since that's the case, why are you still mingling with these evil ghosts? These ghosts want to break through the evil formation and turn the entire human world into a ghost creature."

The Black Mountain Old Demon said in a dark state: "I am already in a ghost state. Of course, I will be mixed with these ghosts. Among the ghost cultivators, there are many ways to control ghosts."

"As for these evil ghosts, what they do is instinctively, and I cannot change their instinctive behavior."

Wu Yi sneered and said, "I'm afraid the behavior of these evil ghosts was carried out by you, and after turning the world into a ghost creature, it will be more conducive to the cultivation of ghost cultivators like you."

The old demon of Black Mountain remained silent. After a while, he spoke: "These are not things you should care about. I just don't want to lose my Ghost King. You can save your life while you leave now. Otherwise, if I change my mind, you might become one of these Ghost Kings."

When the old demon of Black Mountain said this, he subconsciously glanced at the mirror that became a space channel. His actions made Wu Yi feel moved. This mirror should not only serve as a space channel.

Wu Yi laughed and said, "The Thousand-Faced Ghost King dared to change his appearance to deal with me before. It has violated my reverse scale, so it must die. If you dare to stop it, I will kill you."

After saying that, Wu Yi slashed at the Thousand-Faced Ghost King with a sword, trying to cut off the remaining beautiful faces of it. The old demon of Black Mountain saw that Wu Yi dared to take action under such circumstances. He laughed furiously: "What a bold boy. Then I will make you regret it now!"

"Ghost King, go and entangle him. See how he uses the decapitation demon sword to cut off you, the headless ghost!"

The old demon in Black Mountain seemed to be able to control these ghost kings. After hearing his instructions, the fierce ghost king reluctantly gave up the Star Incarnation and rushed directly towards Wu Yi, while the Star Incarnation was besieged by two other ghost kings.

Wu Yi waved the decapitation demon sword and found that the fierce ghost king had no head. The decapitation special effect of the decapitation demon sword was indeed invalid for it. After all, how can people who have no head beheaded?

The decapitation special effect of the Decapitation Demon Sword is useless. Its maximum power cannot be exerted, which is almost the same as an ordinary legendary weapon. Although it is still powerful, it cannot be quickly cut under the sword.

Seeing the Thousand-Faced Ghost King watching the battle with a smile, Wu Yi suddenly used the shuttle void skill to get rid of the entanglement of the fierce Ghost King, appeared beside the Thousand-Faced Ghost King, and slashed dozens of heads on its body with one sword.

The Thousand-Faced Ghost King was next to the old demon of Heishan, so he didn't expect Wu Yi to chase it like this. It roared and hid beside the old demon of Heishan, closer to him.

When the old demon of Black Mountain saw that Wu Yi dared to come beside him to chase the Thousand-Faced Ghost King, he was extremely angry. He saw that his hand shook, and twelve soul-summoning banners appeared. He inserted the twelve soul-summoning poles together. Wu Yi felt the space change, and he came to a plain covered with fog.

On this plain, Wu Yi used the Chaos Heavenly Eye to explore. Although he could penetrate the fog, he could not see the edge boundaries of the plain. In the fog, countless huge black shadows appeared.

Wu Yi looked carefully and found that these black shadows were all huge wild monsters. The monsters had hazy bodies and should be in the state of souls.

At this time, Wu Yi heard the voice of the old demon in the Black Mountain echoing in the plain: "Boy, you have entered my beast demon soul array. In this formation, there are countless powerful beast souls, all of which I collected from a secret realm."

"You just wait to be dismembered by these countless beast souls!"

The twelve soul-summoning banners inserted by the old demon in Black Mountain just now are the array eyes of this formation. The soul-summoning banner is called the beast soul banner. It can collect the souls of beasts that have died in battle and combine to set up a formation like the demon soul array of hundreds of beasts to make the beast soul appear and work together to siege the enemies in the formation.

This is a technique mastered by the old demon of Black Mountain when he was a ghost cultivator. The stronger the beast soul collected on the beast soul banner, the stronger the power of this formation.

Facing the besieged beast soul, Wu Yi waved the decapitation demon sword and slashed repeatedly, but found that these beast souls were combined with the entire formation. Even if they were seriously injured, as long as they retreated into the fog and hid in the beast soul banner, they would recover from all their injuries and come out again.

What Wu Yi wanted to face was the siege of countless beast souls that were almost immortal. In this hundred beast souls, there were more than 300 beast souls above the fourth level, and as long as there were more than 100 beast souls of the fourth level, it was called the hundred beast souls.

If the number of beast souls above level 4 reaches more than one thousand, it can be called the Thousand Beasts Demon Soul Formation, and its power will be even more terrifying.

In addition to these fourth-level beast souls, there are countless other low-level beast souls. They also have such an immortal body, and relying on their numerical advantage can cause certain trouble to Wu Yi.

Among the twelve beast soul banners, there are twelve main beast souls. All of these main beast souls are fifth-level beast souls, that is, beast souls with a level of more than fifty. Their level is close to the reincarnation masters of the fifth level of heaven, and they are even at the same level as ordinary ghost kings.

In other words, this beast demon soul array is composed of twelve ghost king-level beast souls leading other beast souls, and Wu Yi faces great pressure.

Fortunately, after Wu Yi used the Decapitation Demon Sword to behead one of the beast souls, he found that the beast soul was directly destroyed. The Decapitation Demon Sword made an excited sound. The stronger the enemy it beheaded, the more feedback it received.

After Wu Yi beheaded several beast souls in succession, Wu Yi discovered that those beast souls began to pay attention to avoiding Wu Yi's sword skills to avoid being beheaded directly. They would rather be killed in other positions than let Wu Yi beheaded.

Wu Yi found that even if he used all his sword skills, it would be difficult for him to accurately cut the head and neck of the beast souls. After all, there are so many beast souls, and each body is different. It is still difficult to behead quickly.

In this case, Wu Yi simply used his soul energy to increase his level. After upgrading to level 31, he used his extra skill points to learn new swordsmanship.

The decapitation sword light recorded from the Blood Evil Ghost King during this sword technique. The Blood Evil Ghost King obtained the decapitation demon sword for many years. It worked hard to train the accuracy of its sword technique, allowing him to fully utilize the power of the decapitation demon sword.

After so many years of research, he created the sword technique of beheading sword light. After using the beheading sword light, the long sword can differentiate into multiple sword lights and slash towards a large range at the same time. As long as it is within this range, the long sword can cut the key point of the target.

With this decapitation sword light, the Blood Evil Ghost King cuts out the sword force and can easily cut the enemy's head and neck, and use the decapitation special effect of the decapitation demon sword.

When the Blood Evil Ghost King faced Wu Yi and the Invisible Demon Soul, it was because he was completely suppressed by Wu Yi and had no chance to kill Wu Yi, so he was killed by Wu Yi.

After learning the decapitation sword light, Wu Yi tried to use it. He found that as long as he cut off the range of the necks of the beast souls, the decapitation sword light could accurately behead the beast souls, and immediately showed extraordinary power.

This beheaded sword light is indeed a skill tailor-made for the beheading demon sword. Although the blood evil ghost king is not very strong, he relies entirely on the beheading demon sword to deal damage, he has indeed made certain contributions. After years of research, he can create a distinctive sword skill like the beheading sword light.

However, Wu Yi was not satisfied, so he consumed a lot of soul energy and raised the basic level of the decapitation sword light to level five. The level of this skill is level five, but it still consumed a lot of Wu Yi's soul energy.

With the bonus of various skills or status, the overall skill level of the Decapitation Sword Light has reached above 20, and its attributes have been greatly improved. The most important improvement is that the coverage of the Decapitation Sword Light has been improved, making Wu Yi easier to trigger the special effects of the Decapitation Sword.
