Li Yu had no choice but to speed up his practice.

As the practice continues, Li Yu's mental power has begun to transform. If Li Yu's mental power has changed from sand to stones at the beginning, the stones are of course stronger than the sand, so Li Yu's mental power is stronger than the sand.

Ordinary magicians are much more powerful.

Although the spiritual power of the ghosts in front of them is still at the level of stones, their spiritual power is not ordinary small stones, but giant rocks like mountain peaks.

That's why the spiritual power of these ghosts is extremely powerful and can easily deal with Li Yu.

But Li Yu's current mental power has evolved from stone to metal, and it is not an ordinary metal, but a liquid metal.

Li Yu's current mental power is not only strong and tenacious, but also able to change as he wishes, hence the metaphor of liquid metal.

Li Yu did not cultivate the so-called fighting spirit, but the strengthening and mutation of his own mental power was something that really happened.

Suddenly, Li Yu felt that his mental power was a burst. The entire mental power had extended from his body. A silver light belt flew out from Li Yu's body and danced randomly in the void.

The silver light ribbon flew out and hit a ghost, and immediately flew the ghost away. The ghost also made a miserable cry from its mouth. It was obvious that it was beaten.

The ghost that flew out had black smoke coming out of it, and its body was obviously weak and transparent.

Li Yu's mental power can already be released to attack ghosts.

Li Yu clearly felt that his mental power was still undergoing a change, but this change seemed to be restrained. It felt like a chicken was trapped in a strong egg shell and could not break out of the shell.

And out.

The Wanxiang Pearl started to rotate quickly, and a ray of light fell on Li Yu, checking Li Yu's own mental power.

This photo of Wanxiang Pearl really shows the problem.

Li Yu immediately understood that his mental power needed to mutate again, but Li Yu had never encountered such a mutation, so he didn't know how to change it.

In fact, there are many choices for this change, it can be wind, rain, thunder and lightning, it can be frost and flame, or it can be a long sword and a big shield.

However, this kind of change is not a random change, but a change made according to the characteristics of one's own mental power, and it is also one's own perception of spiritual power.

Li Yu closed his eyes completely and ignored the ghosts outside who were attacking crazily. Instead, he was absorbed in his own spiritual power, comprehending his own spiritual power, and looking for the way to advance.

Suddenly, with a bang, the shadow of the Soul-Destroying Knife shattered, and the shattered shadow shrank back to Li Yu's body.

Li Yuzheng calculated his own mental power and already had a clue. The difference was just a slight difference. At this time, the shattering of the soul-killing knife had a great impact on Li Yu. Affected by this, Li Yu's

Mental power is a change.

It was originally a silver band of light, but under this change, the spiritual power turned into a full moon, and the full moon shattered again, turning into a half-moon.

"This is the waning moon." Li Yu whispered.

As soon as Li Yu spoke, the waning moon flew out from behind Li Yu's head, and a silvery white light was created from the waning moon. The ghost that was originally rushing towards Li Yu was illuminated by the light from the waning moon and immediately stopped.

"Destroy!" Li Yu made a faint move in front of him. The waning moon shook and turned into a shadow and flew out. This shadow of the waning moon was extremely fast and penetrated the body of a ghost almost instantly.

The ghosts whose bodies were penetrated by the waning moon immediately collapsed, and one ghost was killed by the waning moon.

Every time Zang Yue kills a ghost, he takes away a bit of spiritual power from the ghost. Zang Yue, who was originally a shadow, immediately becomes more solid.

Li Yu immediately understood that this was when Li Yu started practicing, he realized that he still underestimated the fighting soul method and this bone hall.

Because as Li Yu practiced, powerful forces were injected into Li Yu's body, and then quickly enhanced Li Yu's mental power, allowing Li Yu's mental power to rapidly improve in a very short period of time.

Li Yu could clearly feel that his mental power was getting stronger rapidly. If Li Yu hadn't suppressed this process of getting stronger, Li Yu's mental power would have been able to leave the physical body long ago.

But Li Yu really didn't dare to strengthen his mental power to the point of leaving the physical body, because Li Yu clearly knew who died here, and they all had too much mental power.

He is tyrannical and breaks away from his physical body, but cannot return to his own physical body. In the end, his spirit and soul are separated and he dies.

Li Yu wanted to strengthen his mental strength, but he didn't want to die here.

Li Yu knew very well that he did not need to complete the separation of mental power from the physical body here, he only needed to strengthen his mental power infinitely.

In fact, this is a cultivation method with horizontal development and vertical development.

If those who died developed horizontally, their spiritual power would be at a higher level, but Li Yu developed vertically, and his level would be lower, but at the same level, his strength would be invincible.

This is Li Yu's way of cultivation.

Suddenly, Li Yu felt something abnormal. His mental power actually vibrated, and he was attracted by a powerful force, heading towards a certain place in the void.

Li Yu's mental power was shaken, and his entire mental power was condensed into a ball to resist this attraction.

Although he didn't know the purpose and source of this attraction, Li Yu knew very well that this attraction was definitely not a good thing, and he couldn't be attracted mentally.

Seeing that Li Yu was unmoved by this attraction, he immediately showed a ferocious look, revealing his true appearance.

Li Yu's mental power was shocked. He saw a figure appearing in front of him through his mental power. He looked at him coldly. A terrible force rose from the other person's body, and a terrible attraction towards Li Yu.

Yu was attracted to Li Yu and wanted to draw away Li Yu's spiritual power.

Li Yu immediately understood that the figure in front of him should be a mutant of spiritual power, which can also be commonly called a ghost.

It was those practitioners who practiced the Soul Fighting Method in the past and cultivated their souls out of the body, but were unable to return to the body. In the end, their bodies died, but their souls survived.

These surviving souls eventually became ghost-like existences.

With the appearance of this ghost, ferocious ghosts began to appear around Li Yu, flying towards Li Yu quickly.

Although these ghosts also have fighting power against the physical body, what they are best at is using mental power to attack.

So at the beginning, they did not take action against Li Yu.

Because at the beginning, if they had attacked Li Yu, maybe Li Yu could deal with these ghosts by himself.

But now, Li Yu has fallen into the practice of fighting souls. His body cannot move, and his mental power is not as good as those of these ghosts. It is time for these ghosts to attack.

These ghosts also have a certain degree of intelligence, so they attack in this way.

Li Yu was surprised. Although he had discovered some abnormalities before, he never thought that there were so many ghosts in the Hall of Bones, and they were all such powerful ghosts.

If any of the ghosts here goes outside, they will definitely cause a big disturbance and a bloody storm.

But now, there are thousands of such ghosts rushing towards Li Yu.

It was already difficult for Li Yu to face even one ghost. If he faced a group of such ghosts, he would definitely be dead.

Li Yu already knew that the situation was not good. Without thinking, he used all his magic power. A blurry shadow flew out of Li Yu's body and floated above Li Yu's head.

This vague appearance looks like a big knife, this is the soul-killing knife.

The Soul-Destroying Knife is specifically designed to attack divine souls and is the nemesis of all spiritual bodies.

Li Yu was still unable to use the Soul-Destroying Sword, but he could still use his full strength to create the shadow of the Soul-Destroying Sword.

The phantom of the Soul-Destroying Sword cannot exert even one percent of the power of the Soul-Destroying Sword, but it is enough to deal with these spirits.

The shadow of the soul-killing knife appeared above Li Yu's head, and a gray light immediately enveloped Li Yu.

The ghosts outside were no longer able to cause harm to Li Yu, and were all blocked by the power of the soul-killing knife.

But Li Yu did not completely isolate him. Instead, he opened a gap and allowed the ghost to enter him along the gap.

Then the light of the soul-killing knife is turned off, which is equivalent to closing the entrance and exit, but the power of the soul-killing knife can start to cut and decompose the ghosts that enter.

Li Yu didn't dare to let in too many ghosts at once, because if there were too many ghosts, Li Yu might not be able to deal with them, so he could only let in a small amount, and there would be no way to let in the rest.

It must also be isolated from the outside world.

These isolated ghosts did not stay still, but instead attacked Li Yu who was protected by the soul-killing knife.

If the real soul-destroying knife was here, Li Yu could kill these ghosts with just one strike. But under the current situation, he was unable to do this. The ghost of the soul-destroying knife could

It's good to protect yourself, but it's naturally impossible to fight back against these ghosts.

But it is not easy for these ghosts to kill Li Yu, because Li Yu is protected by the soul-killing knife.

The scene was in a stalemate because of this, but for Li Yu, it was also an advantage. At least Li Yu was safe now.

Moreover, time is in Li Yu's favor. Li Yu only needs to be able to complete his own fighting soul training before the power of the soul-destroying knife is exhausted, and cultivate the so-called fighting soul. Then Li Yu can take action against these ghosts.

But these ghosts are not easy to deal with. Thousands of powerful ghosts are constantly attacking the soul-killing knife, and the shadow of the soul-killing knife is getting weaker and weaker. Once the shadow of the soul-killing knife collapses, Li Yu will die.

One piece.

Li Yu could no longer care so much and immediately started practicing with peace of mind.

The ghosts that were cut open by the soul-killing knife were immediately attracted by Li Yu's spiritual power, and were then swallowed and fused by Li Yu, becoming part of Li Yu's spiritual power and used to enhance Li Yu's spiritual power.

But Li Yu also immediately discovered that although doing so could enhance his mental power, it also contaminated his mental power with many impurities.

Although it can make mental power stronger, the extra impurities are not good news for the growth of mental power. Instead, it makes Li Yu feel bad.

Li Yu made a decisive decision and immediately cut off this part of his mental power. He would rather not have strong mental power, but only need pure mental power.

Mental power is equal to the existence of the soul. For cultivators, the existence of mental power is too important. They must not be careless, let alone do it randomly.

Li Yu knew that although absorbing these souls would strengthen and promote his spiritual cultivation, it would have more negative effects, so he decisively gave up the idea of ​​absorbing these ghosts and instead focused on cultivating and strengthening his own spirit.

force.

The Hall of Bones is really a good place. Li Yu practiced spiritual power here, but his own spiritual power increased rapidly.

Originally, if he had been outside, even if Li Yu spent ten years, he might not have been able to achieve the current results of his cultivation. However, in the Hall of Bones, in just five or six days, it was equivalent to ten years of cultivation outside.

Even Li Yu could not have imagined the effects of more than one year of cultivation.
