The manufacturing of astrolabe is not complicated, and the materials only require sturdiness and a certain spirituality. The key is the internal star-fixing circle.

The complex magic circle was continuously disassembled and analyzed, and a silver rune appeared in front of Su Chong's eyes.

"With this core rune, the formation can be arranged!" Su Zhong was excited.

The second problem in front of him is how to attract the power of the stars to solve the problem.

Formations require spiritual materials as carriers. Like the Big Bamboo Peak Black Bamboo Forest Formation, it uses black bamboo all over the mountains.

These black bamboos are extremely hard, grow slowly, and have been shrouded in the aura of Qingyun Mountain for a long time, and have long since become a spirit seed, so they can be used to set up arrays.

After thinking for a while, Su Chong's eyes lit up, and he suddenly looked at the ground under his feet.

If he hadn't noticed the treasure trove behind him, he would have forgotten that the place where he was standing was not a mountain cliff, but a huge tree.

"Isn't this ready-made material!"

Just do it when you think of it, Su Zhong piloted the light and flew off the platform. I found a thick branch that I hugged together. The sword pill flashed and directly intercepted a large section.

Back at the top of the mountain, Su Zhong began to test.

"Let's cut this branch apart first."

Bite!

With a soft sound, this sword qi only cut off half of the wood in front of him?

So hard?

I didn't feel it when I used the sword pill to slash just now, but now with a single sword qi, Su Chong immediately noticed the abnormality. Carefully observing the fracture, Su Zhong quickly found the reason.

What is hard is the wooden heart in the middle!

Offering a sword pill, he kept chopping at the branches in front of him.

A two-meter-long arm-thick wooden core was completely separated.

This section of wood is the hardest. Su Zhong had already tested it just now. With his current sword qi, it would take three hits to complete.

Excellent array materials!

He was worried about whether the branches would be spiritually insufficient. Now I don't have any worries at all.

"All of them use this kind of wood core as the bearing material, and the formation is absolutely stable!"

He was not in a hurry to test, and flew into the air again to cut off the branches of the tree to find Mu Xin.

The Tongtian Tree does not know how many years it has existed, absorbing the essence of heaven and earth, and growing extremely savagely.

Su Chong just found some huge branches that were slightly old, and obtained a large number of wooden hearts.

Picking, trimming, and polishing, he soon had seventy-two wooden hearts in his hands. Just in case, Su Chong prepared ten more.

The length of each wooden forearm is about the thickness of a fist. The surface is grayish-brown, and from a distance it looks like a gray stone pillar, rather than wood.

"Now that the materials are available, the next step is to transform the formation and try it."

In fact, the transformation of the formation is not difficult. Su Chong's understanding of the Heavenly Machine Seal has long surpassed its creator. He only needed to inlay the star fixing talisman into the formation.

took a wooden heart, urged the sword qi, and runes were carved into it.

The sword qi is sharp and unruly, and it is not the best way to set up the formation. But Su Chong has a lot of sword qi in his body, so he can only use it like this. This required Su Zhong to be more patient and carefully control the direction of the sword qi.

Bang!

The hard wood core exploded into a pile of wood chips.

The sword qi was not well controlled, and the formation was defeated, directly shattering the wooden heart.

Looking down at the drawing process just now, the front is fine, but in the last step, there is a small fluctuation when the formation is hooked. It was only when he was caught off guard that he failed to control and his formation collapsed.

Finding the problem, Su Zhong continued to experiment.

After shattering three more wooden hearts, Su Chong successfully carved the formation.

At this moment, milky white stripes appeared on the surface of the gray wooden core, and the spiral winding seemed to grow on it, which had a strange beauty.

After looking at it twice, Su Chong nodded with satisfaction, and then picked up a piece of wood heart and continued to arrange.

The changed formation requires a minimum of seventy-two wooden cores as a base. And the runes on each piece of wood are different.

It's a lot of work. Only half of the formation base was made, and all the more than eighty pieces of wooden hearts prepared by Su Zhong were scrapped.

"I underestimated the difficulty of the formation." Su Zhong was thoughtful.

After all, the Star Fixation and the Heavenly Machine Seal are different, even if they can be fused, but the time is too short, and there are always some incompatible states in the subtleties.

Su important made small adjustments while making the formation base.

"But it's nothing, anyway, there are a lot of Mu Xin."

After a busy day's work, it was already completely dark outside. Su Zhong found the food he had prepared before and ate it hastily.

There was no Bigu Dan in the Zhuxian World, and Su Chong couldn't help but complain again.

He stopped cultivating, lit the oil lamp that had been prepared a long time ago, and continued to build the formation base in the dim light.

Sharpening the knife is not a mistake for a woodcutter, as long as the formation is completed, his cultivation speed will increase by leaps and bounds.

It's totally worth it to take up a night or two of cultivation time.

Even if he worked day and night, by the time he completed the formation, it would already be three days later.

Holding seventy-two formation bases, Su Zhong circled around the small platform. Put them in the pit that you dug in your free time before.

Then Su Zhong walked into his wooden house and sat on the futon in the center.

The entire formation surrounds his cabin, and the center is the core of the formation.

Closing his eyes, sensing the faint fluctuations between the bases of this formation, Su Chong raised his fingers and shot out a sword qi.

The sword qi hit a formation base on the ground, and a burst of white light flickered, and the gray fluttering formation base immediately lit up with a white light.

Then not far away, the second formation base was touched and slowly glowed. Like dominoes, seventy-two formations were lit up in turn.

Airplanes!

The air fluctuated, and then a pillar of white light went straight to heaven and earth.

At this moment, it is the dead of night and the light penetrates into the sky, which is extremely conspicuous.

Yunmeng Daze, who was calm, was immediately awakened, and all kinds of strange screaming beasts roared one after another.

Su Chong paid no attention to the riots in Yunmen Daze. He felt the power of the stars around him getting richer and stronger, and his eyes were full of joy.

It's done!

……

Liubo Mountain

The Ghost King stood on a hillside with a blank face. The quaint Fulongding beside him constantly emitted a faint red light.

In the distance, a mountain-like beast was imprisoned in place. It lunged left and right, roaring like thunder, and electric light flickered on its body. It was the Ancient Thunderbeast one-legged Kui Niu.

As it struggled, red formation runes continued to appear beside Kui Niu, locking it firmly in place.

Glancing at the disciples who had suffered heavy casualties in the distance, the faces of the ten thousand people were calm:

"Finally got it."

Behind him, Suzaku couldn't bear it, and the disciples who died were all elites of the Ghost King Sect.

"Any news from the Yellow Bird?" Wan Xiang asked lightly.

Suzaku collected his thoughts: "The disciples in the sect investigated, not long ago, there was a change in Yunmeng Daze, and the beasts collided chaotically. According to the records of the sect, every hundred years Yunmeng Daze will appear a hundred beast chaos frenzy. There will be a yellow bird every time, and although it has not yet appeared, it is almost close to its appearance. ”

"Good!" Ten thousand people clenched their fists tightly behind their backs.

"But something is wrong." Suzaku hesitated: "According to the records, it has only been more than ninety years since the last change, and there is something wrong in time. ”

Wan Xiang said decisively: "Send a disciple to explore Yunmeng Daze, we don't need to know the reason for the change in advance, we just need the yellow bird." ”

"Yes!" Suzaku looked at the ghost king whose face was becoming more and more indifferent, and his heart chilled for no reason.

Since Qinglong's death, the Ghost King has become more and more indifferent. Hang out with that mysterious Mr. Ghost all day long. He is also becoming more and more ruthless.

Hopefully nothing will happen. Suzaku prayed secretly. He didn't want anyone to follow in the footsteps of the green dragon.
