Xu Yuxiu spent more than a month in this beautiful place.

Finally, in the "Annotation of the Formation", the knowledge related to the primary formation was thoroughly understood.

Her gaze also began to focus on the primary formation.

Calm and waveless lake, under a tree.

Xu Yuxiu flipped through the book of "Array Annotations".

I saw her eyebrows frowning slightly, as if she was hesitating, and as if she was thinking about something.

"Which one should I learn first?"

It took a long moment for her to furn her brow and her eyes locked on a page of the book.

"Lost Array, let's learn this first."

The Lost Array belongs to the psychedelic formation, and it does not need to depict the aura supply line, nor does it need the materials to arrange the formation, and it can be arranged only by relying on the terrain.

And the place she was in now could just be used to practice arranging the Mystery Array.

Xu Yuxiu got up and began to carefully observe the terrain here.

Psychedelic formations, with great attention to detail, pay attention to the truth.

Therefore, it is necessary to observe the details of the terrain very carefully.

She walked around the lake, then climbed a mountain, and when she stood on the mountain and looked down, she could see the whole picture.

Xu Yuxiu's eyes gradually lit up.

This is a spell that the formation mage must know, the Spirit Eye.

It wasn't difficult for Lingmu to learn, and she also learned this spell by the way when she was studying the formation.

Now is the time to try the magic of this spiritual vision.

After opening the spiritual eye, Xu Yuxiu can see more details.

Looking at the overall situation, she can see a striped road, intertwined like intertwined roots between mountains, forests and lakes.

It may seem like a mess, but if you look closely, you can still see some of the rhythms.

After observing for about a quarter of an hour, Xu Yuxiu took out a pen and paper and began to draw on it.

What she painted was not a landscape, but a striped road.

In addition, in her drawing, she also cleverly dotted nodes between those lines.

That is this place, the intersection of the mountain terrain trend, only by understanding these intersection nodes, can we use these nodes to arrange the formation.

This is where the advantage of the formation comes in.

You don't need to have a very advanced cultivation in the early stage, just like in the Enlightenment, even if you only have the cultivation in the Qi refining period, you can arrange a high-level formation.

But he couldn't arrange a large array, and this was where the limitation of cultivation was.

It's just that this place is not big, and it is only a few hundred meters in size.

Under the backdrop of the mirror-like lake, it is like a mirror, and the surrounding mountains and forests are all decorations on the surface of the lake.

"This place is so like a mirror, why don't you call it 'Mirror Lake'."

Xu Yuxiu's eyes receded, clapped his hands, took the drawn pattern chart, and went down the mountain.

After returning to the cave, she spread out the pattern chart and began to deduce the specific position of the formation.

"This junction is unstable and constantly changing, so it is not suitable as a node..."

"The terrain here is too open, once the formation fluctuates, it is very easy to be recognized, and it needs to be improved..."

It took several hours to draw and pick, and it wasn't until it was dark that she finished marking the nodes of the array.

Some terrain that needs to be improved is also indicated.

Xu Yuxiu put away the pen and picked up the array diagram full of markers, with irrepressible excitement in her eyes.

Maybe it's because I relaxed my mind and lost my previous concentration.

She hadn't been excited for long before she felt a feeling of exhaustion hit her, and a pang of hunger came over her belly.

The deduction formation is extremely exhausting.

Xu Yuxiu didn't expect that the first deduction of the primary formation would make him so tired.

"I'm so tired, I'm so hungry..."

She took out Bigu Dan from the storage bag and ate one, and although the hunger subsided immediately, the exhaustion was still there.

"Forget it, let's rest first."

There was nothing to say all night, and in the early morning of the second day, Xu Yuxiu finally recovered her spirit and walked out of the cave.

She unfolded the deduced layout map, glanced at it again, and when she was sure that it was correct, she went straight to a terrain junction, and couldn't wait to start trying.

Complete maze array, there are twenty-two nodes.

On the formation diagram, she only drew twelve formation nodes, which was the limit of what she could do.

The effect of the maze array arranged in this way will undoubtedly be greatly reduced.

But this is only her first attempt, and she has to practice her hands first.

Xu Yuxiu came to the first terrain intersection, looked around, and after making sure that there was no misunderstanding, he began to condense spiritual power and carve formation patterns on the ground.

Although the formation pattern of the primary formation is more complicated than the basic formation, it is not much more complicated.

Xu Yuxiu confidently began to carve the formation pattern at the intersection of terrain.

However, not long after she started, she suddenly shook her hand, and some of the carved patterns immediately dispersed.

Her first attempt ended in failure.

"What's going on?"

Xu Yuxiu put away her confidence and her face became serious.

"It was clearly portrayed well just now, why is it that the spiritual power seems to be blocked?"

She pondered for a moment, but couldn't find an answer, and decided to try again.

The second attempt, just as she had just carved the pattern to the previous third, suddenly the feeling came back to her.

Her hand paused again, and the carved pattern spread out again.

The two failures in a row made her face solemn.

Xu Yuxiu thought about it, but couldn't find the answer.

So, she took out the "Array Annotation" again and flipped through it carefully.

After some searching, she finally found the answer at the beginning.

"It turns out that this is the problem!"

The formation mage mentioned at the beginning is to arrange the formation with the general trend of heaven and earth.

And Yu Chengdao said in the commentary on this "general trend".

Where various lines intersect, they will repel foreign objects, and the formation patterns are also counted as foreign objects.

As for the solution, Yu Chengdao also mentioned it.

That is to use one's own cultivation to suppress the repulsive force of the intersection.

After getting the solution, Xu Yuxiu closed the book and began to depict the formation again.

The cultivation of the third layer of qi refining was released, and a spiritual pressure spread from her body.

Xu Yuxiu raised his hand, his spiritual power gathered his fingertips, and he began to carve the formation again.

This time, she portrayed very seriously, and as the lines of the formation were depicted to the intersection point, she also felt the existence of that repulsive force.

Fortunately, her cultivation is enough to suppress the repulsion of this node, and this time there is no pause in the portrayal, and it is done in one go.

As her last formation pattern fell, this formation node took shape in an instant.

After Xu Yuxiu saw the formation of the formation node, he breathed a sigh of relief.

"It actually consumed my spiritual power, this is the first formation node, and there is still terrain to be transformed behind..."

For a moment, she felt pressured.

After a short rest, she headed straight for the next meeting point.

Next, she did the same.

It took nearly two days to complete the depiction of all the remaining formation nodes.

The transformation of the terrain is also completed.

When everything is ready.

Xu Yuxiu stood by the mirror lake, pinched the trick and pointed to the sky: "Burst!" ”

There was a change of light and shadow, and then it returned to normal.

If anyone enters here at this time, there is a good chance that they will get lost.
