Sun Xiao's performance made Luo Chen's expression very solemn.

It can be regarded as a simple understanding of the powerhouses of the Nirvana Realm, and it is really powerful.

In the face of the fifth-order formation, they were so calm and calm.

Although it is said that the power of the fifth-order formation is equivalent to that of a strong person in the Nirvana Realm, and under normal circumstances, the power of the formation is stronger than that of a monk, but it also depends on the situation.

There are many changes in the battle, you don't know the opponent's hole cards, and the opponent doesn't know your hole cards.

Of course, there is another point in this is that the Seven Treasure Exquisite Pagoda does not belong to the offensive spirit array.

At least not for now.

Because Luo Chen only has the binding power, as for Ta Ling's so-called demon suppression soul technique, he has not learned it, and it should be said that he has not had time to study it.

Therefore, the use of the Seven Treasures Exquisite Pagoda is still relatively simple.

Still, that's just the beginning.

Looking at Sun Xiao, Luo Chen's hand flashed, and another array appeared, exuding a fierce momentum.

With a wave of the hand.

The array disk instantly enlarged and merged into the void, not affected by the restraining force at all, and once again enveloped Sun Xiao in it.

This is a desolate world, full of swords, as far as the eye can see, all over the mountains and fields, as if it were a world of swords.

The wind blew on a person's face as if it had been slashed by a knife.

It was the fifth-level spirit array ten thousand swords returning to the sect.

The fifth-level spirit array sets a fifth-level spirit array, and the two spirit arrays are superimposed on top of each other.

This operation made Sun Xiao dumbfounded.

"How is that possible?"

Sun Xiao was shocked, as if he had never seen this kind of operation.

Although he was not a formation master, as an elder of the Heavenly Sword Sect, he didn't know how many formation masters he had seen and how many spirit formations he had seen.

He also knows quite a bit about the Spirit Array.

It was because of his understanding that he would be shocked, because what Luo Chen did completely broke his understanding of the Spirit Array.

In his cognition, the formation can be fused, but this fusion is limited to the source array, that is, those fixed formations, because the source array layout needs the assistance of physical objects, so it has the possibility of fusing the formation.

But not all source arrays can be fused, only some special source arrays can be fused.

The most famous is the Qiankun Array, which is said to be able to fuse ten thousand arrays, and the more they are fused, the more powerful they become.

But this is the source array.

It is impossible for the spirit array to be fused, and it is impossible to superimpose.

Because the spirit array is too peculiar, it does not have any physical assistance, and it is built by the formation master using the formation runes.

Formation runes, to put it bluntly, are just a special power.

These runes are built together to form a powerful otherworldly space, and this space is the Spirit Circle space.

All of this is done by the power of nothingness, without the participation of physical objects.

Moreover, the construction is very strict, and the slightest mistake will ruin the formation.

In addition, the arrangement of the spirit array consumes soul power very much.

All these reasons limit the impossibility of fusion or superposition.

Once forced fusion.

This will lead to the instability of the spirit circle and unknown changes.

In this case, there may be problems with the spirit array.

In severe cases, it may directly backlash and seriously injure the formation master himself.

There have been experiments by formation divisions in the past, but none of them have succeeded.

The most famous incident was that there was a ninth-order array master who wanted to try this fusion, and as a result, the spirit array reversed and directly lost his life.

And he still used the two most ordinary spirit arrays.

As a result, an unknown state appeared in the process of merging the two spirit arrays, which was a state that was difficult for even ninth-order array masters to control.

What's even more terrifying is that the death of the ninth-order formation master also brought a person from the city to be buried together.

Because the power of the unknown state is too terrifying, it directly razes the city to the ground.

From then on, let people know that the fusion of the spirit array is terrifying, and if you are not careful, a very terrifying situation will appear.

Moreover, so many experiments have not been successful, which shows a problem, it is impossible for the spirit array to be fused.

This concept has also become a common recognition of all formation masters.

But today, Sun Xiao discovered something, a young man actually fused the spirit array together, and it was so easy.

Of course, this is not a real fusion, it can only be said to be a superposition.

It's also very scary.

"How did you do that?"

Sun Xiao asked in shock.

If this spreads, it will definitely cause a very big sensation, and it can even change the research direction of the Spirit Array.

"Want to know?"

Hearing Sun Xiao's words, Luo Chen smiled, "I'm sorry, I don't want to tell you." ”

For the fusion of the spirit array, no, it should be superimposed, and it was the first time he had done it.

There is only one premise for all this, and that is based on the space of the Seven Treasures Exquisite Pagoda.

If he changed it, he couldn't help it.

Because the perfect state of the Seven Treasures Exquisite Pagoda makes it full of possibilities.

Not only can you cast attacks from the outside world, but you can also stack other spirit circles.

If it is reversed, it will not work to cast the Seven Treasures Linglong Pagoda in the world of Ten Thousand Swords Returning to the Sect, because the Ten Thousand Swords Returning Sect Spirit lineup is no less than other spirit arrays, and the simplest one will not work.

This is the strength of the Seven Treasures Exquisite Tower, which can be compatible with everything.

This is the result of Luo Chen's research on the way here.

This is also the reason why he admires ghosts and fairies so much.

Because the ghosts and immortals have done things that others can't.

Luo Chen felt the current spirit array and also found something special.

There is still a difference between fusion and superposition.

Like the Qiankun Formation fusing with other formations, it can be upgraded and turned into a more advanced formation.

But the overlay is different.

After superimposing, the formation level remains unchanged, and it is still a fifth-level spirit array.

However, the power of the Spirit Array has changed.

That is, the current Ten Thousand Swords Returning Sect World has binding power.

A Ten Thousand Swords Returning Formation with binding power, how powerful it is, you can know it without thinking about it, it's like opening a plug-in.

Luo Chen was quite satisfied with this.

Luo Chen was satisfied, but Sun Xiao was unhappy, especially Luo Chen's ridiculous words, which made him very dissatisfied.

"Boy, you really surprised me, it seems that you really have a lot of secrets on you, since that's the case, then I'm not welcome. ”

Sun Xiao's tone had changed a lot compared to before, and he was much more dignified, and he seemed to notice that Luo Chen's was not simple.

Especially this superimposed spirit array, which made him also feel a deadly threat.

You have to take it seriously, otherwise it is a trivial matter to lose face, and if you lose your life because of this, it will really be over.

"Whoa......

A flash of light appeared in his hand, and a long sword appeared.

The long sword is cold and shining, full of might, and at a glance, there is a chilling feeling.

This long sword made Luo Chen couldn't help but look at it twice, because it was a treasure weapon long sword and a yellow-rank treasure weapon.

Holding the long sword in his hand, the aura around Sun Xiao's body became fierce, and the whole person seemed to have turned into a divine weapon.

"Boy, this is the first time I've used a weapon since I stepped into Nirvana. ”

The voice fell, and the long sword pointed at Luo Chen,

"Make a move. ”
