.”

Xuan Xuan and others, who knew what was going on, did not communicate with Zhang Wei, Xu Wanzhen and others, but went straight into Hexin Building.

Soon, the group of people stopped in front of a quiet room with a closed stone door.

Xuan Xuan waved his hand gently, and the closed stone door opened automatically.

A monk who was sitting cross-legged and pouring a foundation-building pill into his mouth, preparing to refine it and rush to build the foundation, was frightened by this sudden scene and was completely confused.

At first, he was angry when the stone door was suddenly opened forcefully from the outside.

What about the reputation of Hexin Building?!

But it soon turned into panic.

He didn't recognize most of the heads that appeared at the door, but the one or two he knew were absolute big shots on any occasion, but in his sight now, they were even connected to this little person.

Not even a head is qualified to squeeze in the door frame - only half a head is qualified to squeeze in.

When his thoughts returned to himself due to this interruption, they had turned into despair.

The power of the Foundation Establishment Pill had exploded in his body, but he did not give any guidance.

The meridians were broken every inch, and the Dantian was also torn into pieces.

"You... you... poof..."

In grief and anger, the monk, who was ready to embark on a new height in his life, spat out a mouthful of blood with broken internal organs and fell backwards.

Xuan Zhi reached out and waved his hand, and a ray of blue light directly penetrated into this person's body.

The next moment, the blood on the corner of his mouth was still wet, and the monk who was ready to die with his eyes closed looked at Xuan Zhi for a while, and then looked down at himself with his restored body, completely stupid.

A monk from Hexin Tower stretched out his hand and fished the man away.

This man still wanted to open his mouth to speak, but a magic power directly sealed his mouth. At the same time, a jade bottle penetrated into his arms: "Excellent Foundation Establishment Pill to compensate for your loss...shut up!"

Xuan Xuan and others ignored this and strode into the room.

Because the space is not big, it is easier to arrange the retroactive circular light array.

Xuanxu could easily handle it alone without letting anyone else do it.

After he fired more than a dozen formation flags in succession, the time images within the quiet room quickly flowed backwards.

It didn't take long for the time image that was quickly rewinded to return to normal.

The figure of a young monk appeared in the room.

At some point, Zhang Wei was arranged to come to Xuan Xuan and others.

Seeing that figure in the time image, Zhang Wei really... lost his temper at all.

He nodded and said, "That's him."

After the confirmation, Zhang Wei was taken out.

The time image was adjusted by Xuanxu to the moment when Mengzhuang entered the quiet room, and then began to play in sequence.

The former owner of Hexin Building said to Xuan Xuan and others:

“Generally speaking, those who took the Foundation Establishment Pill at Hexin Building and decided to take it on the spot made adequate preparations before coming.

Within three to five days of entering the quiet room, they will officially break through.

But Mengzhuang waited for more than ten days until the next auction was about to begin, and then he successfully passed the test.

At that time, some people were discussing that if he came out later, we would all consider forcing the door to open."

After listening to the story of Qian Hexin, the poster, Xuan Xuan and others also became a little curious about Meng Zhuang's experience of entering the quiet room for more than ten days.

When they saw Mengzhuang again, he did nothing but quietly sat cross-legged for more than ten days. Everyone was still a little disappointed.

If Meng Zhou were here, he would definitely smile knowingly, because he had modified all the traces of his use of knotting methods to arrange the spirit-gathering talisman array, shielding talisman arrays, and using knotting methods to refine elixirs.

Originally, during his retreat, the spiritual energy in this quiet room was so rich that it had semi-liquefied, and it was also not shown in the time-traveling formation arranged by Xuanxu.

In the time images seen by Xuan Xu, Xuan Xuan and others, "Mengzhuang" who entered the quiet room just arranged a set of formation flags throughout the quiet room, improved the quality of the spiritual energy in the quiet room, and then began to cross his legs.

Recuperate.

Xuan Xuan and others saw that "Mengzhuang" had spent far more time here than an ordinary pass-through monk, but did nothing, and they were not without doubts.

But after seeing that "Mengzhuang" didn't take the foundation-building pill at all, but went directly to build the foundation, this little doubt was completely dissipated.

It is certainly a sign of confidence that there is no need to use the Foundation Establishment Pill to break through, but it is also very reasonable to spend more time adjusting the state.

Since then, they have been basically convinced that the Foundation Building Pill that Medicine Master Zhou gave to Yan Xiong was the one that Meng Zhuang took but did not take.

After tracing back all traces of Mengzhuang's past in this quiet room and recording them with photographic stones, Xuanxu also arranged retrospective circular light arrays in several other places in Hexin Building.

Although it was troublesome, all traces of Mengzhuang in Hexin Tower were "recovered".

Before a group of people left Hexin Tower and prepared to go to Zhang Wei's house to "eat a big meal", Xuanxu and others also went to the Sutra Library in the sect and "recovered all traces of Mengzhuang's presence in the Sutra Library."

"Come out.

Naturally, they also saw that Meng Zhuang chose a soul-refining technique called "Cold Pool and Cold Moon Picture" here.

At the same time, Meng Zhuang and Zhuo Yuan were trading stealth and invisibility skills in front of the gate of Hexin Building, and traces of the "Shadow Killing Sword Codex" were also "fished out".

Every time you change places, you have to rearrange the retroactive circular light array.

Xuanxu went from constantly complaining to being unable to complain.

In the end, there was only one sentence on his lips: "No, no, it's too torturous."

Walking on the road to Zhang Wei's house, Xuan Zhi looked thoughtful, looking at the road connecting Hexin Tower and Zhang Wei's house under his feet, and said softly:

"On this road, Mengzhuang must have walked back and forth many times. Do you think there is anything important that happened on this road that we have ignored?"

Xuanxu's eyes suddenly became sharp.

"How about I 'fish out' all the traces of every route he took every time!"

"Is it okay?" Xuanzhi said in surprise: "Of course that's the best!"

However, Xuanxu spread his hands, his eyes were still, and he said without any desire, "Then you'd better kill me."

"Well……"

Only then did Xuanzhi realize that what Xuanxu said was ironic.

This is also the biggest difference between formations and soul arts.

Although the formation reduces the consumption of soul power and mental energy, this consumption can be borne by others after the formation is activated.

But one of its biggest disadvantages compared to soul magic is that it is difficult to achieve continuity.

The formation can only be arranged in a fixed space area, and time can be traced back to this fixed area.

If we were to use formation techniques to dig out all the traces of "Mengzhuang" in Qinglinfang, the amount of work would be so large that it would collapse all the monks in the Fu Formation Hall.

If there are really no more clues, this is the only breakthrough.

But now it is obvious that there are many directions in which we can work hard, so Xuan Xu and others will naturally avoid the hard work of "mining for gold in shit".

After arriving at Zhang Wei's house, Xuanxu commanded the monks of Fu Zhen Hall to set up a large-scale retrospective circular light array around the small courtyard where Mengzhuang had been practicing meditation for a long time.

It not only covers the entire Zhang family, but also includes the lanes outside the Zhang family.

After getting ready, Xuan Xu signaled to Xuan Xuan and others, reminding them to take photos and records, and then activated the formation.

The time image in the small courtyard quickly regressed.

Soon we came to the scene where "Mengzhuang" appeared in Zhang's courtyard for the first time.

Because considering that "Mengzhuang" stayed here for too long, most of them were practicing and used acceleration in some insignificant places.

At the beginning, they were also a little curious about the practice of "Mengzhuang".

But after careful follow-up several times, I found that there was nothing special.

In other words, from a spectator's perspective, there is nothing surprising.

Perhaps the practice of some spells will surprise and novelize ordinary cultivators, but to them, it is not surprising at all.

——What they don’t know is that this is where Meng Zhou spends the most time sneaking into Qinglinfang.

All information that was sensitive and not suitable for display was modified by him using "Time Editing".

Therefore, in the eyes of Xuan Xuan and others, the daily practice of "Mengzhuang" is not surprising, but it is also very boring after watching it for a long time.

Too many times can even give people a strong sense of "sameness".

This is the normal state of practice, and it is the same for everyone’s practice.

Therefore, after confirming that no useful information could be gleaned from this aspect, fast forwarding was naturally used for the part about specific cultivation.

Only when new situations occur, the time image will slow down, allowing them to watch normally.

They also found correspondences in the images one by one with the information given by Zhang Wei, Zhang Yun and Zhang Yi.

There is nothing to say about these.
