Between the formations, there are different ways to arrange them for different grades, and even different levels.

The higher the level, the more complicated the arrangement is, and if there is a mistake in one link, it will lead to the failure of the formation layout, and it may even be counterattacked by spiritual power.

There are also records of people who died after being devoured by the spiritual power of the formation.

It can be said that the higher the grade, the greater the risk of the high-level formation arrangement.

Therefore, compared to alchemists or refiners, the number of array mages is the least in each dimensional space, and it is also the least number of masters who study one of them and deeply cultivate it.

At least in the plane space of the Thousand Flowers Fairyland, there is no formation master who can arrange a heaven-level formation.

Even the existence of the ground-level formation on the iron door below the well had already made the Flame Venerable feel extremely surprised.

It's just that for the current Flame Venerable, the most surprising thing for him, and the most important thing for him, is whether Cao Chuan can skillfully use the formation.

After all, he had already begun to believe that Cao Chuan could definitely master the arrangement and performance of the ground-level formation in a short period of time, but he didn't think that Cao Chuan could directly become a formation master in the process.

After all, even he, the Flame Venerable, had suffered a loss in the formation back then.

But as Cao Chuan left the village alone, preparing to try to test the power of the formation he had laid out in a mountain forest far away from the village, the Flame Venerable realized that he was wrong, after all, he underestimated Cao Chuan's other exposed supreme talent.

This talent is nothing else, it is a talent in the formation.

The Flame Venerable said to the founder of the Holy Spirit Sword Technique in the Sea of Consciousness: "This little guy is definitely the most perverted one we have ever seen in our lifetime, whether it is in cultivation or alchemy, refining weapons and even the talent in the formation path is top-notch. ”

"Even the character and conduct are impeccable."

In this regard, the founder of the Holy Spirit Sword Method also agrees.

Meanwhile.

Cao Chuan, who didn't know what the Fire Venerable and the Holy Spirit Sword Founder were talking to each other in the Sea of Knowledge, had already taken out some of the materials used to arrange the formation from the storage bag, and then made them into the shape and size he needed one by one.

After the preparation was the best, Cao Chuan's slightly squinted eyes suddenly widened, and the spiritual power in his body turned into silk threads under the control of his powerful divine soul power, like another hand, and began to control those materials in front of Cao Chuan.

In this way, various materials are placed in different positions.

As Cao Chuan took out pieces of top-grade spirit stones from the storage bag and placed them in different directions as well.

With Cao Chuan as the center, a cloud of mist suddenly enveloped everything around him.

Looking at the fog that filled the surroundings, Cao Chuan, who was very satisfied with this, would not be confident that the formation he had arranged had taken effect.

In order to test whether the formation was effective, he took out a high-grade spirit stone from the storage bag, and then threw this spirit stone directly in front of him.

The moment the spirit stone came into contact with the mist.

I saw that swords and halberds formed by spiritual power suddenly emerged from all directions, and in the blink of an eye, they smashed the high-grade spirit stone into a handful of powder.

Whether the spirit stone is inferior or superb, it is a very solid existence, and it is something that even a monk in the fairy realm has to spend a lot of effort to break.

However, a high-grade spirit stone was shattered by the spiritual power in the formation in this way, which shows that the attack of this formation is extremely fast and powerful, and it already has the attack ability almost equal to that of a fairy realm monk.

But the formation is just a formation, and it cannot replace the real monk.

Because arranging the formation requires the consumption of a large amount of heavenly treasures and a large number of spirit stones.

And the spiritual power in the spirit stone will be consumed.

The higher the grade and level of the formation, the faster the spiritual power of the spirit stone will be consumed.

It's like this formation arranged by Cao Chuan.

The formation only lasted for a short period of time, and it consumed the ten top-grade spirit stones that Cao Chuan took out before, and immediately lost its effect, and even the heavenly treasures used to arrange the formation also lost its effect.

If you want to arrange the formation again, you need to take out some more treasures and spirit stones.

This is also one of the most important reasons why the number of formation masters is extremely small.

After all, not everyone can use those heavenly treasures and spirit stones without scruples like Cao Chuan.

But the formation is not the only way to arrange the formation.

Some powerful formation masters can also directly use spiritual power to arrange formations.

And although this kind of formation arranged with its own spiritual power is far inferior to the formation arranged with those heavenly treasures and top-grade spirit stones in terms of power, it also has its own advantages.

The advantage of this formation is that the consumption is extremely low, and if it is arranged by a formation master, it can even be maintained for several years or even decades with a piece of top-grade spirit stone.

This is also the direction chosen by most formation mages.

Because this kind of formation is indeed very convenient to arrange, after all, there is no need to use a large number of heavenly treasures and spirit stones to arrange.

As long as the divine soul power is strong enough, the formation can be arranged anytime and anywhere, and it will not take too much spiritual power to maintain the operation of the formation.

Thinking of this, Cao Chuan knew that the formation he had encountered on the iron gate under the well before should be a portable formation arranged with spiritual power.

Because the consumption is very low, it can continue to run on the iron gate.

If it was an ordinary formation, I am afraid that even he would not be able to afford such a way of operation and time.

"But that's a good thing for me."

What was arranged just now was a grade, but it was a ground-level formation in the Heaven and Earth Xuanhuang.

Such a formation can be arranged in an ordinary way, and Cao Chuan can naturally use spiritual power to arrange it again.

So he looked at the useless treasures that had fallen to the ground, and Cao Chuan thought to himself: "When I go back, I will study the ancient and modern formations carefully, and I believe that it won't be long before I can go back to the well and crack the formation on the iron door." ”

Immediately afterwards, Cao Chuan turned around and left the mountain forest, and before leaving, he did not forget to clean up the traces left by his arrangement.

After all, no one knows if anyone will suddenly pass by.

Cao Chuan didn't want to expose himself because of some trivial things, and at the same time, he didn't want Tianshi Village to be affected by external forces.

Although it is located in the middle of nowhere, there is no so-called intrigue, and there is no restriction on the law of the jungle, so it can be said that it is a relatively quiet paradise.

Who doesn't want to find a paradise and enjoy life in a paradise.

Thinking like this, Cao Chuan slowly returned to Tianshi Village.

After returning to the Heavenly Master Village, he immediately returned to his room and began to study the ancient and modern formations.

As for Wen Jinghao, Yu Qinglan and Chu Ningxiang are because they are dealing with the old people in the village, so their relationship is getting better and better, and they are enjoying the original barbecue feast at the invitation of the old people.

It was a lively atmosphere that lasted until late at night.

The Heavenly Master Village gradually returned to tranquility under the light of the starry sky, except for Cao Chuan's room, which was still lit by a lamp.
