In the next few days, Xu Yuxiu lived very calmly.

During the day, he was led by Zhang Yuanyuan and went out to investigate.

When it was dusk, he rushed back and continued to study the array at night.

As she studied the formation chart in depth, she could clearly feel that her understanding of the intermediate formation was deepening and enhancing at an extremely fast speed.

This made Xu Yuxiu feel a little curious.

Could it be that this array diagram is some kind of treasure?

This conjecture did not last long, and she had already rejected it.

Because through the in-depth study in the past few days, she has seen some problems in the formation diagram.

In the room, Xu Yuxiu spread out the formation diagram of the Golden Gate Lock Stone Henge on the table.

Her gaze was fixed on one of the formations, and her eyebrows furrowed slightly.

"The formation here, the more you look at it, the more redundant it becomes..."

She was a little unsure, so she immediately took out the "Formation Annotation", took a blank piece of paper and pen, and began to verify it.

Finally, after some frowning and pondering verification.

Xu Yuxiu stretched her brows at this time, and there was a clear look in her eyes.

She put down her pen and said to herself: "The five formations here don't exist in the Golden Gate Lock Stone Formation at all!" ”

Immediately, she was a little puzzled: "Since these five formations shouldn't exist here, why are these five formations in the formation map?" Test? ”

She couldn't figure it out, but her intuition told her that there must be a mystery hidden in it.

It's just that with her ability now, she can't fully peek into the hidden mysteries.

Following.

Xu Yuxiu and Zhang Yuanyuan climbed to the top of a mountain.

Looking from top to bottom, you can see most of the scenes of Zhang's family at a glance.

Suddenly, Xu Yuxiu's eyes moved slightly, raised her hand to one place, and asked, "Senior sister, what kind of place is there?" ”

Zhang Yuanyuan looked at the place she was pointing at, and said, "There is a deep pool there, which is the source of the stream under the mountain. ”

Hearing this, Xu Yuxiu had a flash of inspiration in her mind, and her eyes showed a look of thought.

Zhang Yuanyuan looked at her like this, and couldn't help asking, "Senior Sister Xu, is there any problem there?" ”

Xu Yuxiu shook her head and didn't answer, but asked, "Senior sister, can you go there and have a look?" ”

"Of course you can, you can look around Zhang's house casually."

With that, the two of them walked towards the place where the deep pool was.

After a while, when the two of them came to the place where the deep pool was.

Xu Yuxiu saw a mouth of the pond that was about three feet square.

Just standing here, you can feel a cool breath.

If you look closer, you can see that the water in the pool is clear, and you can see the bottom at a glance.

However, as you look down, you can only see a dark patch, and you can't see the bottom of the deep pool.

Xu Yuxiu looked at it for a while, and unconsciously a chill rose from the bottom of her heart.

She felt like a bottomless black hole, as if one could fall into it and be swallowed by it without paying attention.

After only looking at it for a moment, she withdrew her gaze.

"Senior Sister Xu, do you see something?" Zhang Yuanyuan saw her retract her gaze and immediately asked.

Xu Yuxiu's face showed a hint of solemnity: "It's weird here!" ”

"Weird?"

Zhang Yuanyuan looked puzzled, "Then do you want me to go down and have a look?" ”

She is the eighth layer of Qi refining, and with her own cultivation, it is not a problem to enter a deep pool.

Xu Yuxiu shook her head, "I feel that the bottom of the pool is very dangerous, it's better not to go down to explore in person, senior sister, you can use your divine sense to investigate." ”

Divine Sense Exploration.

Zhang Yuanyuan also understands why Xu Yuxiu said this.

After all, in her opinion, Xu Yuxiu only has the cultivation of the fourth level of Qi cultivation, and her divine sense is naturally inferior to hers, and she can avoid great danger by using her divine sense to investigate.

She nodded, and then let out her senses and plunged into the deep pool.

Xu Yuxiu watched from the sidelines, and secretly pinched a talisman in her hand.

After a while, Zhang Yuanyuan suddenly shuddered and withdrew his divine sense.

"Senior sister, have you found anything?" Xu Yuxiu immediately asked.

Zhang Yuanyuan slowed down for a while before shaking his head and replied: "No, the further down the pool is, the colder it becomes, and my divine sense is only thirty zhang deep before I can stand it." ”

Thirty feet...

A cultivator of the eighth layer of qi refining, his divine sense can release more than forty zhang, to say the least.

Xu Yuxiu didn't expect this deep pool to be deeper than she expected.

In this way, it is impossible to find out.

Zhang Yuanyuan was also glad in his heart at this time, and he did not go directly in person without recklessness.

She felt that if she went deep into the position of the divine sense, she was afraid that even the spiritual power in her body would be dull.

In that case, she would be in danger herself.

What's in this pool?

Zhang Yuanyuan had such doubts in his heart.

Xu Yuxiu was silent for a moment before saying, "Senior sister, let's stop here today, I have some questions that I want to deduce and verify on the formation diagram." ”

"Okay then."

Immediately, the two stopped staying and went straight down the mountain to the main house of the Zhang family.

Just after the two left.

The water in the deep pool was surging, as if something was about to rush out.

Suddenly, a figure appeared, and several spells were punched out in his hand and printed in the pool.

After a while, the surging water in the pool gradually subsided.

"I almost let you out, probably because I felt your daughter's breath!"

The man's eyes were cold, and his tone was cold, "I didn't expect that little girl to be so keen, and she discovered the strangeness here so quickly, it seems that she has to do it quickly!" ”

With that, the figure disappeared, and calm returned to the edge of the pool.

Back in the attic, Xu Yuxiu didn't rest, and immediately took out the formation diagram and spread it out.

Then he took out the compass, and at the same time took out the topographic map that he had observed and drawn in the past few days, and began to deduce the entire array map according to the topographic map.

With the infusion of spiritual power, the compass lit up with lines.

Between the flow of lines, following a special law, different indications are revealed.

Xu Yuxiu picked up the pen and began to sketch the formation nodes on the topographic map.

Although we haven't seen all the terrain yet, there is nothing else to do about it right now.

Only then will she be able to verify her guesses.

It took her a day and a night to deduce.

It didn't end until noon the next day.

As soon as she put down her pen, a strong feeling of dizziness hit her mind.

Xu Yuxiu only felt a flower in front of her, and almost fell unsteadily.

At this moment, a jade arm stretched out and held her up, so that she did not fall.

"Senior Sister Xu, how are you?"

Zhang Yuanyuan's somewhat anxious voice came.

Xu Yuxiu raised her eyes and saw her anxious look, and shook her head, "Senior sister, why are you here?" ”

"I didn't see any trace of you all morning this morning, so I came over by myself, and I didn't bother you when I saw that you were deducing the formation diagram."

Zhang Yuanyuan explained slightly, and immediately showed concern, "None of this matters, your current body is the most important!" ”

"I'm fine, it's just that the deduction of the formation consumes too much mind, and it's okay to take a break."

Xu Yuxiu said weakly.

Hearing this, Zhang Yuanyuan breathed a sigh of relief, "Then I'll help you to bed, and you can rest well in the past few days." ”

Xu Yuxiu nodded.

Zhang Yuanyuan helped her to the bed and lay down.

At this moment, Fauber came to the attic, "Miss, the head of the family has returned with a message. ”

"What!"

When Zhang Yuanyuan heard this, his face suddenly showed joy, but after seeing Xu Yuxiu, he seemed a little hesitant.

"Senior sister, go and go about your business."

Zhang Yuanyuan hesitated for a while, but finally nodded, "Then junior sister, you have to take care of yourself, I will come to see you later." ”

With that, she followed Fauber out of the attic.
