Gu Yuan had never learned the formation technique, but as a Heavenly Master who had already started, he still knew some basic knowledge of the formation.

A formation, he must have several things!

The first is the pattern of heaven and earth, commonly known as the formation pattern!

The pattern of heaven and earth is the basis of a formation, just like a person's body, without a body, there is no qiē, and the body is the capital of the revolution.

The pattern of heaven and earth can determine the attributes of a formation, which can be an attack formation, a phantom formation, or a defensive formation.

Just like the human body, teeth, nails and other places are very aggressive, but the ears and nose are very fragile, and the bones are more resistant to blows, which means defense.

Language, expressions, eyes, etc., all have a confusing effect, it is said that the phantom array! Therefore, people cannot lack any of the above, and as a formation, they cannot do without the pattern of heaven and earth!

And there is one more thing that cannot be missing in the formation, and that is energy.

Just like a person eats, a formation cannot run without energy, and a person can only starve to death without food! Therefore, a formation needs an energy supply.

And the energy supply body is the eye of the formation, and only it can make the formation have energy to work!

Generally, the lines of heaven and earth are engraved on the inside of the array (for example, the beads on Gu Yuan's hand are engraved on its inside), and of course, there are also carved on its surface!

Of course, this energy supply body, that is, the eye of the formation, is not to provide the energy supply of the formation all the time, it is mainly the energy supply when the formation is activated, and it may be more appropriate to call it the carrier of the heaven and earth pattern!

As long as the formation is activated, it will naturally be able to absorb the energy of the outside world to replenish itself, and then the energy of the array will be filled again! Of course, it cannot be ruled out that some low-level one-time array eyes, the formation is all maintained by the energy of the array eye, and when the array eye energy is used up, the formation will disappear.

The formation pattern and the formation eye, these two parts are indispensable for the formation.

Of course, with these two parts of the formation, it is still an incomplete formation, because it still lacks one thing, the formation heart!

The heart of the formation, as the name suggests, refers to the core, center, and brain of a formation.

A person without a brain is a dead person, and in the same way, a formation without a formation heart is called a dead formation! The bead in Gu Yuan's hand is a formation whose brain has been asleep.

The role of the array heart in the formation is very large, the most basic role is to start the operation of the formation, some will also recognize the master, can be automatically started, and even there are active protectors, more powerful array heart will even produce its own consciousness, with independent thinking ability.

There are strong and weak hearts, just like human brains, there are brain-dead vegetative people, there are fools with low intelligence, and there are smart geniuses, but there is no suspense, they all have to have brains. It can be seen that the importance of the heart of the formation is not overwhelmed by the formation pattern and the formation eye!

Looking at the black beads in his hand, Gu Yuan knew that there was nothing wrong with the formation pattern and formation eye, and the only problem was in the heart of the formation.

"As long as the heart of the formation is awakened, the ability of this bead will be restored, hehe, when the time comes, even Jiangzhou will not be afraid of his hard work. "Gu Yuan was completely silent at this time, and he was completely immersed in the beautiful fantasy of the beads.

At this time, the heart of the bead was already asleep due to time, which was equivalent to the brain waves stopped beating. And the only way to get it beating is to resonate with it with a foreign object!

And this external object refers to the unique perception of the Heavenly Master, and only the perception that can sense all things in heaven and earth can sense the existence of the center of the array. "Just do it when you think of it, Gu Yuan is already a little impatient.

The perception began to extend into the black beads, and after passing through countless formations, Gu Yuan's perception came to the center of the formation and saw the legendary array heart!

The center of the array was in the shape of a long line, like an earthworm, and shimmered with a black ghostly light.

Now that he saw the heart of the formation, Gu Yuan no longer hesitated, and immediately began to control his perception and vibrate with the heart of the formation according to some basic knowledge of controlling the vibration!

With the vibration of the array, the beads seemed to come to life, and the faint light began to light up, but it was bright and extinguished, and it was extremely unstable.

Gu Yuan knew that this was completely triggered by his own perception, and it would take a lot of time for the formation heart to be completely resurrected. In fact, if you want to repair the beads, there is another way, and that is to directly change the heart of the formation!

That method is very fast, but Gu Yuan doesn't have that ability, because only real array mages know how to change the formation heart, so Gu Yuan can only use this stupid method now.

Time passed little by little, and I don't know how long it had been, the ghostly light that shrouded the ancient plains suddenly stopped flickering, and instead turned into a huge and dark light shield that completely covered him in the center.

At this time, Gu Yuan finally opened his eyes, and a smile appeared on the corner of his mouth, "It's done." ”

Yes, after Gu Yuan's continuous efforts, he finally succeeded in awakening the heart of the formation, which also marked that Gu Yuan would have a defensive treasure.

Looking at the light shield that surrounded him, Gu Yuan was extremely excited, he knew that Jiangzhou would no longer pose any threat to him now.

After activating the bead, Gu Yuan found that this bead was very good, it was not a one-time array eye, as long as it was activated, it immediately absorbed energy from the outside.

After activating the formation, the heaven and earth patterns inside the bead spread to the outside of the bead, which is an ability that all formations have. The wider the range of the envelope, the smaller its power will be, and conversely, the smaller the enveloping range, the greater the power!

Of course, this can only be adjusted by a celestial master with perception!Gu Yuan didn't think much about it, and began to control the hood to become smaller, until its defense layer just clinged to his skin, and he didn't stop.

One of the reasons why Gu Yuan has reduced the defensive circle is that it can increase its defensive power, and another reason is that it can avoid its exposure, and no one will not be moved in the face of such a treasure!

"Good, good!" Furuhara put the beads into his clothes, as they would lose their effect if they were put in a storage ring.

"Jiangzhou, I hope you don't come to look for death!" As soon as he was ready, Gu Yuan looked at the door of the tent, and his gaze was very deep at this time!

Two days later, in the center of the entire barracks, in a huge tent that was several times larger than the average tent!

A young man of about twenty years old sits in the center of the top position, the young man looks ordinary and ordinary, there is nothing special, the only thing that is different may be that the eyes are sharper than ordinary people.

On either side of the head, there are two rows of monks, and they all have a common characteristic with the young people sitting in the first seat, that is, they are relatively young in appearance, and the oldest should not be more than forty years old!

And in this hell, the origin of these young people is needless to say, that is, the people of heaven!
