A pale cyan crystal, a rune crystal, which contains the phantom imprint of all the formation refining methods below the third order of the formation master.

Chen Hao found that the pale cyan crystal was really a detailed method of formation, and its content ranged from the unfathomable composite formation to the simplest communication formation, which was all-encompassing, and it was simply an encyclopedia of formation analysis!

Priceless! At this moment, only these four simple words appeared in Chen Hao's mind. The pale cyan crystal in front of him can almost be regarded as the essence of all the formations in this life of this formation master, and it is definitely his Dao inheritance!

Especially when he saw the clothes and face of this formation master, Chen Hao's eyes widened in shock.

No one understands better than him how unique that formation master has in the entire formation, so no one understands better than him how precious the old man's formation experience imprint is......

That is the essence of the formation ancestor's lifelong study of the formation!

As soon as he thought of this, Chen Hao's eyes were suddenly filled with an incomparable surprise.

Chen Hao sat cross-legged on the spiritual platform, urging his spiritual power to study it carefully.

Although this small pale cyan crystal seems to be small, the knowledge, essence, experience, and experience of various formation making methods contained in it are as vast as a sea of smoke, which makes Chen Hao breathtaking.

Even with his current six senses, it was very difficult to find the method of the sound transmission formation he needed in such a rich knowledge reserve, and he finally found it after carefully looking for a stick of incense.

The sound transmission formation is a fairly widely used formation in the formation system, and it can be regarded as one of the basic formations that ordinary formation mages must learn to learn formations.

The sound transmission formations made by ordinary array mages can only penetrate a range of one mile at most, and some can only penetrate a distance of ten miles.

Although the effect of the sound transmission formation is different because of the different grades, it is a life-saving medicine talisman that many formation mages must have, after all, when encountering danger, the longer the distance, the more likely it is to increase the chance of escape.

The refining method of the sound transmission formation is very cumbersome and complicated, and the runes of the sound transmission formation must be drawn first.

Then arrange them according to a certain rule, which is not a trivial matter, and the distance between each rune and the other runes should be exactly the same.

Despite this, it takes extremely high level of cultivation and patience to arrange the runes one by one, carefully studying and grinding in every part of the two runes.

This first step alone would take nearly a pillar of incense, but this was only the first step in the sound transmission formation.

After the runes are arranged, the next step is to inject the aura into this large array, and the different runes, the number of aura and the type of aura are different.

In fact, this is the main driving force for the operation of the sound transmission formation, and it is also the most difficult and cumbersome procedure in the entire sound transmission formation production process.

In fact, these spiritual powers cannot be perfectly integrated into one, and each attribute has a spiritual power conflict with the aura of other attributes, which involves the rules of heaven and earth, the evolution of the five elements, the harmony of attributes, the laws of the human body, the distribution of meridians, and so on.

The complexity is beyond the imagination of ordinary people.

In fact, after all the aura was thrown into the big array, the real highlight began to come!

The moist light in the depths of Chen Hao's eyes flashed away, and he seemed to be affected by an unknown force and fell into a special mysterious realm.

Chaotic and hazy, it seems to have changed back to the gestation state of the fetus.

The mind is empty, everything flows through the heart, and everything is under control!

Daigo empowerment, the spiritual platform is empty, and there is one mind.

With the rapid transformation of two palms in front of him, like butterflies piercing flowers, crystal clear and colorful runes appeared from the palms.

These runes come in a variety of colors, shapes, and crystal clear, and at first glance look as delicate as the craftsmanship of carving crystals.

A full thirty runes slowly fluttered around his body, rippling out beautiful waves of spiritual light.

In the colorful light waves, Chen Hao's face was solemn, and he began to carefully observe and carve these talismans one by one, slowly re-understanding the way of the formation that he had not yet fully comprehended.

As time passed, the sigils floating around him began to become more elaborate and detailed one by one, as if every tiny detail was constantly being perfected.

Airplanes!

As soon as his mind moved, the golden mana converged on his hands, and then Chen Hao began to seal, but it was extremely jerky.

One, two, three......

In an instant, within thirty zhang with Chen Hao as the center, a light breeze suddenly blew, and at the same time, every time Chen Hao pinched a spirit seal, a pale golden trajectory like ripples shot out from his hands and appeared somewhere in the void.

One, two......

Soon, Chen Hao had already pinched the second spirit seal, and two points of pale golden light spread all over the void around him, faintly forming a formation, but it was not complete.

Three spirit seals in a row were successfully pinched out, Chen Hao's role was solemn, and the fourth spirit seal appeared, once it was successful, he completed most of the sound transmission formation.

Airplanes!

However, at this moment, the spirit seal in Chen Hao's hands collapsed and dispersed.

Chen Hao has been trying to arrange the sound transmission formation in the future, but none of them have succeeded, but although he has been failing, Chen Hao can vaguely feel that in the failures again and again, it seems that he is rapidly approaching success.

Chen Hao's eyes were calm, and in the next moment, his arms shook violently, and the five spirit seals in his palms suddenly swept out, and then disappeared as quickly as if they had merged into the air.

Between Chen Hao's fingers waving again and again, a thick golden spiritual power light swam back and forth like a golden dragon.

With a flick of his fingers, he saw that the golden dragon disappeared as if it was a raindrop that melted into the seawater, but when the golden dragon disappeared, Chen Hao suddenly felt a sudden wind blowing, which made him feel a little unstable.

When the spirit seal disappeared into the air, Chen Hao's eyes narrowed slightly, and he could vaguely see that the five spirit seals, each occupying five strange positions in the air, shot out from the spirit seal, and then intersected and connected in a rather complex trajectory......

And when that last ray of light completes the complex and obscure interweaving, the golden dragon disappears.

Chen Hao immediately felt that the surging speed of the heaven and earth spiritual qi there had become much faster.

In the air, there was a faint light flickering, and then quietly fading, and it would be difficult to detect it if it were not for careful sensing.

Unconsciously, Chen Hao's own Dao Ji became more flawless.
