After speaking, Zhou Miao forcefully withdrew the arm that was still under treatment from Nangong Piao's hand, although Nangong Piao was a little reluctant, but the bones were no longer in trouble, and there was no bleeding, so he could only suspend the treatment in Zhou Miao's cold eyes. Then without waiting for Zhang Longqian to put forward his opinion, Zhou Miao put the rune paper on the ground one by one, and soon put a gossip look around the spherical core in front of her, and then she pasted the rune paper into the air at eye level, as if there was an invisible pillar there, and all the rune papers were firmly pasted in the air, and then she changed slightly upwards and arranged the rune paper.

Looking at the increasingly complex formation of the rune paper that Zhou Miao posed, Nangong Piao slowly widened his eyes.

“…… No way? Tracing back to the roots?! That's ......! This is a course for the middle students of the 'Zonghengjia'! ”

Although Zhang Longqian didn't understand the terms Nangong Piao said, he probably understood that he was talking about Zhou Miao's very powerful meaning, Bai Lu of course also heard this meaning, the two of them looked at each other and smiled, and then Bai Lu proudly said what the two of them thought.

"As long as it's research, there's nothing that can stump Xiao Miao! She has been working on physics all these years and what has she learned from it...... What theorem...... Oops, anyway, it's a law I don't understand! Anyway, she's applying these to spell-related things, and it's like a tiger! Now there's no formation she can't study! ”

Although it was the first time that he knew that Zhou Miao was immersed in physics in order to better study spells, and he was a little speechless about this fact, Zhang Longqian still showed the same proud smile as Bai Lu.

It's even happier than being praised by others.

Hearing Bai Lu's words, Nangong Piao's eyes widened, and he cast a look of adoration at Zhou Miao.

As if the others didn't exist, Zhou Miao silently continued to fiddle with the rune paper, and soon a three-dimensional formation was presented, and many rune papers were firmly fixed in the empty space to form a shape more than one person high, like a huge hourglass that was concave in the middle.

After arranging it, Zhou Miao sat back on the ground, and began to change the complex seal between her hands, and then she suddenly closed her hands, and the sudden sound of clapping her palms was extremely loud, as if echoing in the entire forest, and then, the spherical core that was originally in the middle of the Bagua Array on the ground gradually floated, hovering in the position of the three-dimensional formation concave - that is, the "waist" of the hourglass - slowly began to rotate, and at the same time, starting from the vicinity of the core, the rune paper that formed the formation lit up with a strange light one by one.

Zhang Longqian couldn't say what color the light was, he only felt that it was a little illusory, even if the light became very bright, he couldn't feel dazzling, and the spherical core surface of the metal was also dyed with a strange color.

"I'm starting to look for Yin and Yang Eyes now, you guys wait honestly."

After saying this, Zhou Miao closed his eyes, and the rune paper that formed the formation began to slowly change its position interactingly, and the light emitted also flickered slightly, making Zhou Miao look a little ethereal under the reflection of the light.

Nangong Piao sat down obediently, looking at Zhou Miao's appearance of closing his eyes and seriously controlling the formation, he still couldn't help but sigh in a low voice: "But Zhou Miao's classmate is really amazing!" What so many elites in the Dharma Hall couldn't do, she did. ”

Then while waiting, Nangong Piao said slowly.

The Tracing Array is an extremely complex object-seeking array, consisting of one hundred and eight rune papers. The production of these runes must be very good, and the content of each one is different, and the position of the arrangement naturally cannot have the slightest deviation, plus this is a three-dimensional formation, and the arranger must have the mana of a medium student or above to be able to set the rune paper in the air.

In addition to these requirements, the most important thing is the familiarity of the arranger with the formation.

The difference between the "array" and the "array" is that the "array" is simply based on pure mana to construct a pure energy array, which can resonate with natural spiritual power to the greatest extent, thus causing various changes; The "foundation" of the "formation" is the thing that has an actual body, such as the spirit stone with natural spiritual power, and the elaborate rune paper, etc., and the arranged "foundation" is connected in series with mana to form a "formation" with an obvious shape, which can be used to urge its operation with less mana, and achieve a similar effect as the magic circle.

However, the biggest disadvantage of the formation is that if no one controls it, it cannot be constantly changing like the circle, but is fixed.

The fixed formation cannot be changed with the change of natural spiritual power, and it cannot work, and can only be called a "formation", not a "formation". The key to the formation lies in the word "performance", people who are familiar with the formation can keenly capture the changes in the spiritual power of nature, and change the arrangement of the formation with this change, so as to deduce a variety of different formation changes, in order to finally achieve the goal, and its complexity is absolutely unimaginable. Therefore, even in the academy where spells are taught, only the sparsely populated branch "Zongheng Family" will specialize in studying formation changes.

In order to fully exert the effect of tracing back to the source, you must be able to skillfully deduce thousands of basic formations and master almost all derivative changes. This huge amount of content is simply impossible to grasp without decades.

Of course, there is no shortage of such excellent elites for the Dharma Temple, so when it first knew that the Yin Yang Eye was born, the Dharma Hall also wanted to rely on the origin tracing array to find it, because the accuracy of this formation is extremely high, and it is far more efficient than sending people out to search for this primitive method. However, since it is called "Tracing the Source Array", of course, you can't look for something without clues, and if you want to find the target accurately, you need a part of the target, or something that is almost exactly the same as the target's fluctuations.

But as we all know, no one knows what the fluctuations of the yin and yang eyes are, and theoretically speaking, there will not be two things in the world that are the same as fluctuations, and it is even more impossible to artificially make things close to the yin and yang eyes, so in the end, the Dharma Temple can only give up relying on the tracing of the origins of the array, but adopt the old method of letting everyone go separately to find it.

Saying that, Nangong Piao couldn't help but praise again: "She's really amazing!" I didn't expect that she would be able to master the tracing array at her age, and she would be able to make things like fluctuations and yin and yang eyes, which is incredible! ”

As for the fact that Zhou Miao will know the fluctuation of yin and yang eyes, everyone has no doubts. After all, even Nangong Piao could detect the fluctuations of the yin and yang eyes, and Zhou Miao, who had been staying in Zhongkun and had a better brain than Nangong Piao, would be really strange if he couldn't detect it.

Thinking like this, Zhang Longqian smiled and pulled Bai Lu to sit down next to Nangong Piao.

"Because it's Xiao Miao, this kind of thing is taken for granted. After all, her brain structure is different from ours, and she is a genius that we can never catch up! ”

Nangong Piao nodded immediately, and thought deeply: "Originally, I only knew that she was a mortal genius who would always be the first in the grade, but now it seems that even in the Dao Law Realm, she is an out-and-out genius!" I'm afraid that entering the academy is the same as Yan, and I will soon be able to reach the level of graduation! ”

Hearing this, Zhang Long subconsciously raised his eyes to look at Cang Yan, he was still some distance away from everyone, and did not cast a little gaze here, he looked up quietly at the gradually brightening sky between the treetops, and stood with his hands in his pockets leaning on a tree, only half of his back was exposed in Zhang Longqian's sight.

Lonely back.

Looking at the cold figure, Zhang Longqian slowly lost his mind, and then suddenly a flower appeared in front of him, and some images flashed.

The little girl with pigtails was blinded by the rainbow in the night sky, and then transformed into a big bird with feathers like flames.

Blue-eyed, white-beaked, one-legged, eccentric but intimidating, and incredibly beautiful.

The large, one-legged bird bent its slender neck and let out a crisp and shocking cry towards the night sky.

"Bi-Fang-"

The strange cry carried an inviolable Ling Ran, which made people tremble.

And underneath the huge firebird, there stood a small figure.

A figure so lonely that you want to cry.

There was an inexplicable throbbing pain in his chest, Zhang Longqian frowned and clenched his heart, the strange image immediately faded, and the scene in front of him turned into a scene where Bai Lu, who was slightly angry, was raising his fist and saying something to Nangong who was smiling bitterly.

What is that?

Feeling that the pain in his chest was gone away after a moment, Zhang Longqian smiled casually at Bai Lu, who turned his gaze, but he was puzzled in his heart.

I think I've seen those images......

As she recalled, she quickly remembered when it was.

Just a few hours ago, when she was still at the place where Nangong Piao and Cang Yan lived, these images flashed in her sleeping dreams.

What's that, exactly? The firebird, and the unseen figure, could it be......

Thinking about it, Zhang Longqian's gaze unconsciously fell on Cang Yan's body, and the darkness gradually faded in the dim morning light, and the cold and lonely figure seemed to be about to merge into the only remaining darkness around, and it seemed that it would disappear at any time.

Zhang Longqian's chest throbbed again.
