The effect of cultivation so far, but in just five or six days in the Hall of Bones, is equivalent to the effect of more than ten years of cultivation outside. Even Zhang Cheng could not imagine such a cultivation effect.

But Zhang Cheng is getting more and more anxious, because the light of the Soul-Destroying Knife is getting dimmer and dimmer, and it is about to be broken by the ghosts outside.

Zhang Cheng had no choice but to speed up his practice.

As the practice continues, Zhang Cheng's mental power has begun to transform. If Zhang Cheng's mental power has changed from sand to rocks at the beginning, the rocks are of course stronger than the sand, so Zhang Cheng'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 mental power of these ghosts is extremely powerful and can easily deal with Zhang Cheng.

But Zhang Cheng's current mental power has begun to evolve from the foundation of stone to metal, and it is not an ordinary metal, but a liquid metal.

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

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

Suddenly, Zhang Cheng felt that his mental power was a burst. The entire mental power had extended from his body. A silver light belt flew out from Zhang Cheng'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.

Zhang Cheng's mental power can already be released to attack ghosts.

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

And out.

The Vientiane Pearl started spinning quickly, and a ray of light fell on Zhang Cheng, checking Zhang Cheng's own mental power.

This photo of Wanxiang Pearl really shows the problem.

Zhang Cheng immediately understood that his mental power needed to mutate again, but Zhang Cheng 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 based on the characteristics of one's own spiritual power, and it is also one's own perception of spiritual power.

Zhang Cheng closed his eyes completely and didn't care about the ghosts outside who were attacking crazily. Instead, he was absorbed in his own spiritual power, comprehending the power of 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 Zhang Cheng's body.

Zhang Cheng calculated his own mental power and already had a clue. It was just a short difference. At this time, the shattering of the Soul-Destroying Knife had a great impact on Zhang Cheng. Affected by this, Zhang Cheng'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." Zhang Cheng whispered.

As soon as Zhang Cheng's words came out, the waning moon flew out from behind Zhang Cheng's head, and a silver-white light was created from the waning moon. The ghost that was originally rushing towards Zhang Cheng was illuminated by the light from the waning moon and stopped immediately.

"Destroy!" Zhang Cheng moved a little towards the 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.

Zhang Cheng immediately understood that he was using these ghosts to polish his own waning moon.

After all, the waning moon is also a mutation of mental power, and these ghosts are also mutations of mental power, and the two are originally connected.

As soon as Zhang Cheng started practicing, he realized that he still underestimated the Battle Soul Technique and this Hall of Bones.

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

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

But Zhang Cheng really didn't dare to strengthen his mental power to the point of leaving the physical body, because Zhang Cheng 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.

Zhang Cheng wanted to strengthen his mental strength, but he did not want to die here.

Zhang Cheng 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 Zhang Cheng developed vertically, and his level would be lower, but at the same level, his strength would be invincible.

This is Zhang Cheng’s way of cultivation.

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

Zhang Cheng's mental power was shocked, 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, Zhang Cheng knew very well that this attraction was definitely not a good thing and he couldn't be attracted mentally.

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

Zhang Cheng'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 power rose from the other person's body, and a terrible attraction towards Zhang Cheng.

Cheng attracted Zhang Cheng and wanted to draw away Zhang Cheng’s spiritual power.

Zhang Cheng immediately understood that the figure in front of him should be a mutant with mental 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 Zhang Cheng, flying towards Zhang Cheng 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 Zhang Cheng.

Because at the beginning, if they had attacked Zhang Cheng, Zhang Cheng might be able to deal with these ghosts by himself.

But now, Zhang Cheng is trapped in the practice of fighting soul method. 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 like this.

Zhang Cheng 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.

And now, there are thousands of such ghosts rushing towards Zhang Cheng.

It is already difficult for Zhang Cheng to face even one ghost. If he faces a group of such ghosts, he will definitely be a dead end.

Zhang Cheng already knew that the situation was not good. Without thinking, he used all his magic power. A blurry shadow flew out from Zhang Cheng's body and hovered above Zhang Cheng'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.

Zhang Cheng is still unable to use the Soul-Destroying Knife, but he can still use his full strength to create the shadow of the Soul-Destroying Knife.

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 Zhang Cheng's head, and a gray light immediately enveloped Zhang Cheng.

The ghosts outside were no longer able to cause harm to Zhang Cheng, as they were all blocked by the power of the soul-killing knife.

But Zhang Cheng did not completely isolate himself. 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.

Zhang Cheng didn't dare to let in too many ghosts at once, because if there were too many ghosts in, Zhang Cheng 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 Zhang Cheng, who was protected by the Soul-Destroying Knife.

If the real Soul-Destroying Knife was here, Zhang Cheng could kill these ghosts with just one strike. However, under the current situation, he is unable to do this. The ghost of the Soul-Destroying Knife can

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 Zhang Cheng, because Zhang Cheng is protected by the soul-killing knife.

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

And time is in Zhang Cheng's favor. Zhang Cheng 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 Zhang Cheng can take action against these ghosts.

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

One piece.

Zhang Cheng could no longer care so much and immediately started practicing with peace of mind.

The ghosts that were cut open by the Soul-Destroying Knife were immediately attracted by Zhang Cheng's mental power, and then were devoured and fused by Zhang Cheng, becoming part of Zhang Cheng's mental power and used to enhance Zhang Cheng's mental power.

But Zhang Cheng also immediately discovered that although doing so could enhance his own mental power, it also contaminated his own 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 Zhang Cheng feel bad.

Zhang Cheng made a prompt 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.

Zhang Cheng 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.
