Even with so much care, the entire process of setting up the formation was full of stumbling blocks and revisions.

But now, as it is used in actual combat again and again, on the one hand, the formation is constantly being improved and simplified. On the other hand, all those who set up the formation are becoming more and more skilled and their understanding is getting deeper and deeper.

It becomes easier and easier to arrange the retroactive circular light array.

Looking at the rapidly forming retrospective circular light array, Xuan Xu was thinking, "It would be great if we could further improve and simplify it and condense it into one array disk."

That way, he only needs to be responsible for making the formation disks at the inner gate, and he no longer has to go out for urgent tasks from time to time.

"Palace Master, the formation is ready."

Just when Xuanxu was thinking about how to turn the retrospective round light array into a magic circle, a monk came to him and reported back.

Xuan Xu said to Xuan Xuan beside him: "Junior sister, let's go over."

…

As the formation started, the time image in this area quickly regressed.

When Chu Zheng, Yu Peng and others arrived here with confused expressions, the time image happened to go back to the correct time node.

Xuan Xuan pointed to the time image suspended at a certain moment and asked Chu Zheng:

"Is this right here?"

Chu Zheng, Yu Peng and others opened their eyes wide and looked in the direction of Xuan Xuan's finger, with expressions as if they had seen a ghost.

In the direction of Xuan Xuan's finger, in a room, another Chu Zheng was handing a token of magic weapon into the hands of "Physician Zhou".

And as they looked at each other, the paused time image began to "play" normally.

As a result, the picture that originally only existed in Chu Zheng's memory, and became increasingly blurry as time passed, was presented clearly and unmistakably in front of everyone in such a unique way.

Chu Zheng also passively relived this long-standing memory.

Just when Chu Zheng, Yu Peng and others were so shocked by what they saw that they were speechless, the eyes of Xuan Xuan, Xuan Xu and other Qingxuan Sect monks looking at Chu Zheng quietly became much softer.

To them, as long as Chu Zheng didn't lie and create extra difficulties for them, he was a "good comrade."

If they didn't find any trace of "Physician Zhou" in this place, then they would have to consider another way to entertain him.

By tracing back the circular light array and finding traces of "Zhou Pharmacist", the next thing will be easy to handle.

Stroke forward and downward along the line of "Zhou Yaoshi".

With the ability to go back in time, the hardest thing is to find the first thread.

As long as the first thread is found, the following information can be sorted out continuously along the thread, which is very convenient.

With this idea in mind, Xuan Xuxing hurriedly started "getting to the bottom of things".

But the result was like a basin of cold water poured on the heads of Xuan Xu, Xuan Xuan and others.

Moving forward in the timeline, "Zhou Pharmacist" seemed to appear out of thin air in front of the courtyard.

The traces of its past were cut off at the moment it appeared in a hidden alleyway around the corner.

"Invisible?"

"Earth Escape?"

"Shadow Escape?"

"..."

Various speculations ran through everyone's minds, but there was no definite answer.

Finally, Xuan Xuan looked at Xuan Xu and asked, "Senior brother, can you show the methods he used?"

Xuanxu shook his head and said: "It can't be done."

Although he had already expected it, Xuan Xuan couldn't help but sigh after receiving a clear reply.

Then, Xuanxu adjusted his direction and moved down the timeline.

As a result, soon after "Zhou Pharmacist" left the courtyard, all clues and traces about him were completely lost.

Regretful Xuan Xuan murmured:

"Tell me, is this 'Physician Zhou' acting like this out of caution, or is he consciously avoiding it?"

Xuanxu was stunned for a moment, then he was horrified and said:

"Avoid what?

Did he expect at that time that someone would use the method of going back in time to observe him?

So, he took action in advance?

Is this...is this a little too outrageous?"

Seeing Xuan Xu's gaffe, Xuan Qing next to him shook his head and said:

"Senior brother, you are scaring yourself. Even if the other party consciously avoids such methods, it is far less scary than you think.

This is probably just a mandatory, fixed code of conduct for this organization."

After his explanation, Xuanxu's expression softened slightly, he nodded slightly and said thoughtfully:

"If this is really the code of conduct of this organization, does it mean that this organization has dealt with forces with the ability to go back in time, and may have even suffered heavy losses, so this code of conduct was born?"

Xuan Qing, Xuan Yan, Xuan Min and others nodded slightly, agreeing with Xuan Xu's guess.

"That makes sense."

As they spoke, they looked at each other.

Almost at the same time, an answer emerged in their minds.

"The Palace of Constellations."

After coming up with this guess, inexplicably, everyone felt a little better about this force that still existed in the fog.

Well, as long as you don't deal with the constellations, you can try to be friends with Virgo.

——Except these lunatics from the Lihen Cult.

…

"But in this case, wouldn't the clues about 'Physician Zhou' be broken?" Xuanxu said regretfully.

Xuanqing burst out laughing, and Xuanxu turned his head to look over curiously.

"Senior brother, are you stupid? The clues can't be broken so easily!" Xuan Qing said, looking at Master and Disciple Yu Peng.

Xuanxu followed her gaze and looked over.

Xuan Xuan has already walked towards Yu Peng and Chu Zheng.

Xuan Qing did not join in the fun. Instead, he walked up to a burly man and asked:
Chapter completed!
