The self-detonation of the entire formation was extremely terrifying.

If it is said that the opening of the formation teleportation has already used forty percent of the energy of the entire formation, then the self-explosion of the formation is equivalent to the explosion of the remaining energy.

And this is also Chu Nan's calculation.

Even if he didn't find the tracking blood ball on his body, he would find a way to introduce those two into the formation, so that the formation would explode by itself!

He believed that under the self-explosion of the formation, even if the two of them did not die, they would inevitably suffer heavy losses, and they would not be able to continue to hunt him down.

When he finished all this, his whole body suddenly felt uncomfortable, and a feeling of weakness that he had never felt before quickly spread throughout his entire body, making him unable to continue to maintain his pseudo-demon form, and quickly returned to his human form.

"What's going on?"

Chu Nan's face turned pale for a while.

He was not injured, but now this sudden weakness made him feel like a kind of life overdraft, and his whole body was in a cold sweat.

"Is it because of my use of magic?"

Chu Nan's heart moved.

Guessed the reason.

The ...... he used

After all, it was not his own magic power, and at the same time, the strength of this magic power was far beyond his current level stage.

Even if he was able to use this kind of magic power that was too much stronger than himself through the method in the Demon Emperor Inheritance, he would pay a huge price!

This kind of price is particularly huge, which is directly reflected in his life, so that his life is overdrawn!

That is...... Reduction of lifespan!

This also made Chu Nan's heart solemn.

If he continues to fight with magical power, then it is tantamount to a crazy consumption of his life.

Although he didn't know how many years of life he had lost earlier, this sense of weakness made him realize that he must not use the magic power in the sealing magic weapon to fight at will......

This feeling of weakness lasted for a long time before it gradually dissipated.

Although he is no longer weak, his lifespan has indeed decreased.

This also sounded the alarm for Chu Nan, making him unable to use his magic to fight anymore.

"I need to give birth to my own magic as soon as possible......"

Chu Nan thought to himself in his heart.

After this battle, he had a more intuitive feeling for the power of magic.

Although what he used this time was the high-end magic power in the sealing magic weapon, this magic power was relatively easy in dealing with the cultivators of the Spirit Fusion Realm, but the calmness of his mind under the pseudo-demon form allowed him to make some clever calculations. In terms of combat, he also has an advantage over him in human form.

It's just that the birth of magic power can't be achieved in a while, after all, Chu Nan is just a pseudo-demon, not a real demon......

Soon, after adjusting his state.

Chu Nan searched the surrounding environment, wanting to find his current location as soon as possible.

It was a woodland, and Chu Nan didn't see any villages or towns nearby.

However, when he was about to leave, he found something strange in this woodland.

On the trunk of an inconspicuous tree, he noticed a black mark, the entire mark was semi-hidden, and it was almost impossible to see without looking closely.

"It's ...... Magic Seal!"

Chu Nan's eyes flashed.

Recognized that it was a mark left by the demon.

It's just that although he recognized it as a magic seal, he couldn't know the information contained in the magic seal, and he needed to crack it.

Chu Nan had a strong premonition that the information in this demon seal was very likely to be related to the demon head.

He decided to crack the seal.

In the Demon Emperor Inheritance, there is a way to crack the magic seal, and if Chu Nan uses the magic power in the sealing magic weapon, he can crack it in a short time.

It's just that now that he knows that using the magic power in the sealing magic weapon will cost his lifespan, he naturally doesn't dare to use this magic power that is too much stronger than himself at will.

In this way, it will take some time for him to crack this magic seal.

But right now, the most important thing for him is to find the whereabouts of the demon head as soon as possible, and naturally he will not be stingy with this little time, and the whole person is fully committed to cracking it.

Meanwhile.

Here in Chu Nan, the whole body and mind were indulged in the time when the magic seal was cracked.

Inside a sprawling mansion in the county seat of Wyvern.

Zhao Dun, the county guard who was in charge of the entire Feilong County, was hunched over at this time, accompanying an old woman like a servant.

This old woman was old, on crutches, her face was full of wrinkles, and her eyes seemed to be too old to open.

However, in front of him, the county guard Zhao Dun didn't dare to take a breath.

At this time, the old woman was standing at the highest point of the mansion, and it seemed that she could see the entire Feilong County.

Her gaze first looked in the direction of the docks in Wyvern County, where the airships of the Holy Cang Academy docked.

"This opportunity to refine the demon head, the Holy Cang Academy will be our strong competitor, but ...... In the absence of the Holy Firmament War Beast, it is unlikely that they want to compete for this opportunity. ”

The Wyvern County guard nodded to the side.

"The reason why they chose to come to us for the trial of elite students is to get this opportunity to refine the demon head, but it's a pity...... They are doomed. ”

"Here...... After all, it is our Zhao family's territory, how can we let others take away the opportunity that belongs to our Zhao family's children?" the old woman shook her head and smiled.

"But I heard that among this group of elite students of Shengcang Academy, there is a little guy named Chu Nan, who seems to have caused the Zhou family of the Divine Grace Group to chase and kill, and even the people of the Zhou family have entered the game this time, will this bring some variables?"

The Flying Dragon County Warden was a little worried.

"The Zhou family? ”

The old woman smiled confidently.

"Although they looked like they were rushing at that little guy on the surface, we could see early on that they also wanted to take this opportunity to compete for the demon head, we were prepared, and the Zhou family was not afraid. ”

The Wyvern County Warden nodded.

He knows it well.

Whether it was the Shengcang Academy or the Zhou family, before they came, they had already greeted their Zhao Group and sent some benefits, so that the two sides reached an agreement before they could enter Feilong County and participate in the battle for the demon head this time.

At the moment, the only thing that the old woman and the Feilong County Guard are more worried about is mainly the problem of the demon head.

Because this time for them, although it is an opportunity to refine the demon head, it is also a ...... for the demon side A chance to give birth to a demon general!

It's a game between the two sides!

Usually, in the four parts of the Exorcism Alliance, it doesn't happen often, but every once in a while, it appears.

In this regard, both the human side and the demon side have acquiesced in this game.

Because this kind of game is good for both parties.

Once the human side succeeds, then the Spirit Fusion Realm that successfully refines the demon head can be born!

Refining the Demon Head...... and refining ordinary demons, they are two completely different concepts!

Refining the Demon Head is not only able to form a 100% Dan, but even after the Dan, in the Dan realm, it is far from being comparable to the ordinary Dan realm.

Among the powerhouses in the human race today, many of them have refined the demon head when they are in the Spirit Fusion Realm, so that they can reach a higher cultivation realm.

This also makes many strong people under powerful forces find ways to create some opportunities for their descendants to refine the demon head.

......

At this time, within the twelve towns occupied by the demon leader Su Ze's side, many people had already gathered.

In addition to the many elite students of the Shengcang Academy, the Zhao Consortium also had a lot of people from the Zhao family who came here, and even the people of the Zhou family who came to kill Chu Nan also appeared in this area.

Each of them learned the location of the demon head in a different way, and they came to various locations one after another, waiting for the demon head to appear.

It was also at this time that Chu Nan successfully cracked the magic seal and obtained the information in the magic seal.

"It's ......"

Shock appeared on his face.

Be frightened by the message contained in the sigil.

He didn't expect the information contained in this to be...... A set of methods of killing and devouring humans!

This magic seal was sent by the demon head.

He wants the demons here to see this method of killing and devouring through the magic seal, so as to kill the human race.

Through this method of killing and devouring, not only can they absorb the flesh and blood of human beings after killing them, but they can even ......

Absorb and cultivate!!

The higher the cultivation, the greater the improvement that can be brought to them after absorption!

However, this method of killing and devouring can only be carried out under a special kind of magic night.

According to the message in the magic seal, there will be such a magic night here in the near future!

"It's really a game!"

Chu Nan's heart suddenly understood.

He finally understood the intention of the demon leader Su Xue!

They deliberately occupied this area, just to use this area to lay out, so that this area could meet many conditions for the arrival of the Demon Night, and then they used the whereabouts of the Demon Head as bait to introduce a group of Spirit Fusion Realm cultivators into the bureau, and when the Demon Night came, they would ...... Start the killing!

After understanding the intentions of the demon leader's side, Chu Nan also completely understood the experience of these elite students this time.

He knew very well that the reason why the Holy Cang Academy chose the training location here was obviously to give them the opportunity to hunt the demon leader!

This is both a game for the Demon Leader and an opportunity for them to hunt the Demon Leader.

"Gambling ......"

Chu Nan's eyes flashed, and he saw the whole thing clearly.

At the same time, he also realized that in addition to them, the elite students of the Shengcang Academy, the people of the Zhao family would also enter the game.

Their targets are all Demon Heads!

And the demon leader is here to kill them and devour their flesh and blood and cultivation.

Chu Nan understood that no one must be able to understand the whole situation like himself now.

Even if the people of the Zhao family knew that this was a game, they didn't know about the situation on the demon head's side, and the demon head didn't know the human side's information.

Only Chu Nan is here that he can grasp the intelligence of both sides through the change of identity, and he can see the entire situation extremely thoroughly and clearly.

"If I had done a better job, maybe I could ...... Stay on top of the situation!"

Chu Nan's eyes flashed, knowing that this was his biggest advantage!

At the same time, it will also be the dependence of whether he can become the biggest winner in this game.

He was also very clear about the benefits of refining the demon head, and he himself wanted to refine the demon head.

In addition, he also has concerns about them.

At the moment, there may be some elite students who have not been involved in this game, but the vast majority of elite students have definitely entered the game.

For everyone, although this is an opportunity, it will also face a huge crisis.

"I can't let them have anything to do with them no matter what. ”

After Chu Nan understood everything, he quickly began to think about his next move.

The most important thing now is mainly his disguise in terms of identity.

"With my current pseudo-demon form, although ordinary demons can't see anything, they just don't know where the demon head is...... Will there be some clues? ”

Chu Nan's heart was a little worried.

On the surface, he was not worried that he would be exposed, but worried that he would reveal flaws in his communication with the demon head.

Especially when he doesn't dare to use magic power easily, it is even more difficult to prove it through the use of magic power.

After some consideration, Chu Nan felt that the safest way was to disguise himself as an ordinary demon not to pretend to be a demon with a high status.

In this way, it will not attract the attention and suspicion of the demon head.

At the same time, in terms of magic, there is no need to worry about affecting your lifespan.

However, in order to disguise himself as an ordinary demon, he first needs to capture a demon and extract the magic power from its body.

"When this game begins, let's find a demon to extract mana!"

Chu Nan was not in a hurry to find the demon now.

Instead, I am ready to learn more about the use of magic in the Demon Emperor Inheritance.

The more he needs to master, the more he can disguise it.

At the same time, the method of killing and devouring in this magic seal was also familiar to him.

In this way, under Chu Nan's preparation, time passed day by day.

More and more people are being drawn to the area of these twelve towns through various ways and methods.

Almost all of the people who came were in the Spirit Fusion Realm!

Finally.

On this day.

In the sky of this area, a waning moon appeared......

The moment this waning moon appeared, the entire sky instantly turned black.

This kind of black, different from ordinary black, carries a kind of palpitating coldness, like an abyss, spreading this area, making everyone in this area have a chilling feeling in their hearts.

And the weirdest thing is that outside this area, the sky is bright and clear, but in this area, there is darkness.

Meanwhile.

This dark night area has also formed a powerful seal, making this dark night area seem to be divided into a separate world, and people outside the area cannot step into it, and people in the area cannot get out of it.

"Magic Night!"

At this moment, everyone knew that it was the coming of the magic night.

Some people who have experience in fighting demons can see that the magic night that is coming now is very different from the ordinary magic night.

Under this magic night, all of their bodies seemed to be stuck in a quagmire, becoming sluggish, and the spiritual power in their bodies began to drain......
