The black and white array sword has the ability to carve bones and carve arrays, and Gu Zheng has harvested a lot of mysterious beast bones during this time, which he used to practice his hands, and he soon had an experience.

For ordinary sword masters, the sword is a godsend, and it is accompanied by the dantian of the human body. However, Gu Zheng's black and white array sword was not innate, although it had the same ability, it could not enter the body, and could only exist in the Void Bone Ring.

Speaking of which, Gu Zheng also felt more and more magical, his black and white array sword was stored in the bone ring, and it could imperceptibly open up the bone ring space, making his bone ring space bigger and bigger, which has to be said to be an unexpected gain.

The sword master carves the bones and carves the array, and needs to understand the sword diagram, borrow the void formation power in the array sword, like carving a work of art, and reproduce the god and shape of the sword diagram on the beast bones.

Judging the strength of the formation bones mainly depends on two things: one is the grade, which corresponds to the cultivation realm of the martial sword master, and needs to be carved by the mysterious beast bone of the corresponding realm;

The same beast bones, the same sword diagram, and different array swordsmen can carve formation bones with completely different powers.

Gu Zheng is now carving the heavy formation bones of the Condensation Realm, and he will hardly fail, but he can only carve the formation bones of the Dacheng Method. This is mainly due to his lack of understanding of the sword diagram, if he can't understand the sword diagram himself, how can he carve a deeper formation bone?

But even so, if it is known that Gu Zheng will become a Condensing Realm Dacheng Formation Sword Master in a few days, I am afraid that it will be shocking. Gu Zheng didn't know that he was already far ahead of the sword masters of the same generation of the Sword Mansion, and those new disciples were still in the exploration stage.

Gu Zheng was able to get started as a sword master so quickly, because he had ten years of experience in carving the Yunyu Sword Diagram, and as a martial sword master, he already had a deep understanding of swordsmanship. Of course, the all-encompassing Ten Thousand Beasts Sword Diagram in the Black and White Array Sword is also Gu Zheng's strongest capital.

In the world, I am afraid that there is no sword mansion that can provide such a complete sword map for the formation sword master to carve the formation bones.

The carving of the Meteorological Realm Formation Bones was very different from the difficulty of the Condensation Realm, Gu Zheng had tried several times before, but unfortunately he had scrapped all the middle-level beast bones in his hands, and none of them succeeded.

Now that Gu Zheng had two more middle-level Xuan Beast corpses in his hands, he could continue to try.

Gu Zheng knew that his divine soul was powerful, and the void array power that he could call was completely enough to carve the bones of the meteorological realm. However, the carving of the formation bones is a meticulous work, and what is required is the fine control of the sword and the strength of the formation.

If you can't do this, you will never be able to become a Formation Sword Master, and if you want to become a Meteorological Realm Array Sword Master, you have to do this step more perfectly.

First, the pangolin was quickly dissected, showing a small white bone, and then the pangolin sword diagram was found from the black and white array sword. Carving the original picture with the original bones is also a shortcut to forming a formation. The first step of the basic mold base can be almost omitted.

Next, what Gu Zheng needs to do is to carve the scales, barbs and even hair of the pangolin on top of this pair of animal bones, so that its appearance can reach a high degree of restoration.

Moreover, in this process, he wanted to incorporate the strength of the Void Array into it, just like opening up human-like meridians for the beast bones, to carry, circulate, and release the mysterious power within the beast pill.

At the top of Chifeng, Gu Zheng sat upright on the boulder, holding the beast bone in his left hand and the black and white sword in his right hand. The whole figure turned into a stone statue, only the black and white array sword in the shape of a pen in the right hand, quickly or slowly pen out the sword.

This scene is quiet and beautiful, as if blending into the mountains and becoming a picture.

From noon to sunset, three full hours later, the black and white array sword in Gu Zheng's hand suddenly slammed, and the formation bone in his left hand suddenly turned into powder, and the meteorological realm formation bone carving failed again.

But seeing that Gu Zheng was still immovable, not even his eyes changed, his empty left hand did not tremble at all, but the black and white array sword on his right hand was still carving in the air, he seemed to be in a daze.

"Whew...... I was just one last step away, but I already knew what the problem was. Half an hour later, Gu Zheng exhaled a long breath, his eyes shining, and he did not feel the slightest sense of decadence because of another failure.

Closing his eyes and savoring the carving just now, when Gu Zheng opened his eyes again, he was already full of energy, and he believed that this time it would be successful.

The long skeleton of the Thornback Rock Beast fell on the boulder, Gu Zheng stood up, took out the Sword Diagram of the Thornback Rock Beast and understood it carefully, as if he wanted to engrave the entire Sword Diagram into his mind.

Another half an hour passed, and Gu Zheng suddenly put away the sword diagram, holding the black and white array sword, walking around the beast bones, and dropping the sword like a god.

This time, Gu Zheng's movements were obviously much faster, and the white bones, along with the carving of the black and white array sword, fell all over the ground with bone chips.

An hour later, the beast bones that originally exuded the aura of death and silence were transformed into a resurrected thorn-backed rock beast, lifelike, as if it was about to incarnate in the next moment.

"It's done!" Gu Zheng suddenly put away his sword, and a full sense of accomplishment arose.

"Try it!" Gu Zheng took out the beast pill of the thornback rock beast, and fell into the chest and abdomen of the beast bone with a snap of his fingers, and the entire beast bone was instantly activated, and his empty eyes suddenly lit up.

Roar......

A beast roar that shocked the mountains and wilderness spread in all directions, and the beast bones suddenly gave birth to light, and a fleshy and fleshy thorn-backed rock beast stood impressively on top of the boulder, looked up to the sky and roared, and then prostrate in front of Gu Zheng, lowering its proud head.

"The fourth stage of the meteorological realm has finally succeeded. Gu Zheng couldn't be excited in patience, he had already judged the grade of this formation of bones.

Although there is only the fourth stage of the meteorological realm, and the method is small, Gu Zheng knows that this is already extraordinary. If he carved other sword drawings from the bones of the Thornback Rock Beast, he was afraid that he would not even be able to reach the second stage of the Meteorological Realm.

"The weather formation is complete! Which senior brother is refining bones here? Tang Zhige of the Tang Clan's Sword Mansion met with the senior brother. In the deep mountains in the distance, Lang Lang's words suddenly came, echoing endlessly, shocking the beasts.

Gu Zheng was shocked in his heart, waved his hand to put away the formation bones, and looked at the distant night, secretly awe-inspiring.

"Very strong!" Although Gu Zheng had not met, he had already sensed the strength of the other party, which was enough to surpass him in the cultivation realm.

Facts have proved that Gu Zheng's guess is not wrong, the two figures in the distance are like lightning, sweeping between the red peaks, as if entering a no-man's land. Just a moment later, the other party crossed a red peak and came to Gu Zheng.

There was a man and a woman, the man was handsome and extraordinary, and the woman was tall and feminine, standing there, even the night could not hide their peerless demeanor.

"Is this senior brother a sword master who has just refined his bones?" The young man wore a jade crown on his head, and spoke warmly, with a look of surprise.

"I can't see through!" Gu Zheng was secretly shocked in his heart, the man in front of him should be older than himself, and his cultivation was unfathomable, and it was difficult for him to investigate.

As for the woman, she was a little green and arrogant, and snorted at this time, "Cousin, he is about the same age as me, how can he be the Weather Array Sword Master just now?"
