Xuan Qing's sudden words made Yan Xiong feel that his heart was suddenly grabbed by a hand. Not only did his heart beat faster, but his body shook uncontrollably.

Having witnessed Qingxuanzong's miraculous time-traveling ability with his own eyes, he did not dare to make any quibbles.

Otherwise, just give him a "big close-up" and everything will be clear.

Yan Xiong's reaction was as if he was unexpectedly startled, and he nodded and said, "Yes."

Xuanqing nodded and asked again: "Where is the jade slip?"

"A secret method of foundation building." Yan Xiong said honestly.

Xuan Qing nodded again.

There is nothing wrong with the Foundation Establishment Pill and the Foundation Establishment Secret Technique.

As for the specific secret method, she did not ask.

First of all, this has nothing to do with their current main goal, it is just a side detail. Even if Senior Brother Xuanxu masters the traceback circle light formation, he cannot really trace back everything in detail. He must grasp the priority and cannot be taken away casually.

partial; partial;

Secondly, Qingxuan Sect has no shortage of similar secrets, and its value is different for Yan Xiong, a casual cultivator who has struggled from the bottom, and for a high-level Qingxuan Sect like her.

To her, this is just something within easy reach, but to the other party, it is not an exaggeration to say that it is more important than life.

The subsequent investigation will require the active cooperation of these people, and she does not want to cause conflict with this non-mainline information.

…

On the other side, Xuan Xuan was interrogating Master Chu Zheng and Yu Peng.

Xuan Xuan narrowed his eyes slightly and stared at the master and apprentice looking up and down.

"Did Master Zhou really mean 'Qihuangmen'? Are you sure you heard it right?"

The two nodded and said, "OK."

Xuan Xuan looked at Yu Peng and said, "So, when you heard the name 'Qihuangzi' in Hexin Tower just now, you had some special reaction. What did you think of?"

Yu Peng's expression paused for a moment, then nodded and said: "Yes."

Xuan Xuan nodded and said: "Indeed, I will inevitably have some associations with Qihuangmen and Qihuangzi."

As she said that, she turned to look at Chu Zheng and asked, "But why do I see no reaction from you?"

Chu Zheng originally wanted to say, "I have a bad memory as I get older," but looking at Xuan Xuan's bright and lively eyes, there seemed to be a ray of fire burning in the depths of the pupils, and he immediately swallowed the nonsense words that came to his lips.

He went back and said with a wry smile:

"As I get older, I think more and become timid. I thought that doing more would be better than doing less, so I tried to fool me, but I didn't expect that your eyes were as bright as lightning... I had become a clown myself."

Xuan Xuan looked at Chu Zheng twice, nodded and said, "You must be honest."

Then he continued to ask, and Du He on the side also participated.

The monks of Fu Zhen Temple led by Xuan Xu were not idle either. According to Yu Peng's confession, they were ambushed by Du He in Yu Peng and were rescued by Pharmacist Zhou. They also contacted Pharmacist Zhou again after leaving Nuanyun Valley without saying goodbye.

The roadway and the hut where Yu Peng originally lived were traced back in time.

It accurately reproduces the traces of time more than ten years ago as dictated by Yu Peng and Du He.

After "capturing" the traces of Pharmacist Zhou again, they habitually followed the timeline forward and back again.

But whether moving forward or backward, the traces of Pharmacist Zhou will completely disappear in a very short period of time.

It seemed that the only purpose of his appearance was to reconnect with Yu Peng, Chu Zheng and others.

Once or twice, it can be said that it is due to habitual caution.

But this happened again and again, and Xuan Xuan and others gradually leaned towards another possibility.

"This must be a strictly enforced code of conduct."

"This is to consciously avoid detection methods such as time regression."

So far, they have not dug out much useful information, and the traces they have glimpsed are not even the tip of the iceberg.

But Xuan Xuan, Xuan Xu and others were excited, yet awe-inspiring.

They were already convinced that they had indeed dug up a huge "big fish".

However, this "big fish" is hidden so deeply that there is no trace of it in reality. Only by means of time retrieval can we find some clues.

The senior brothers and sisters looked at each other and suddenly felt a heavy weight on their shoulders, feeling that they had a great responsibility.

"Hey, our Qingxuan Sect's rise is still too short, and we don't know how many things we don't know."

Xuanzhi felt something inexplicable and sighed.

After digging up all the traces of Pharmacist Zhou in Qinglinfang, and without any more clues, Xuan Xuan, Xuan Xu and others decided to set off for Nuanyun Valley.

They have a feeling that they will gain more there.

Of course, it's not that these are the traces of Zhou Yaoshi in Qinglinfang, but following the line of Yu Peng, Chu Zheng, and Du He, they can only get these.

Of course they knew that Pharmacist Zhou's activities in Qinglinfang were far more than this, and he must have more actions.

But the crux of the problem is that apart from Yu Peng, Chu Zheng, and Du He, they have no other way to intervene.

It is impossible to track the past of each monk without any clues. With the number of monks coming and going from Qinglinfang and the complexity of the flow and changes, the difficulty is comparable to finding a needle in a haystack. Even the monks of Fuzhen Temple will be exhausted ten times.

You may not be able to find the "needle".

Therefore, there is no point in continuing to pursue the Qinglinfang line.

Just when they were about to leave——

"etc."

Xuan Xuan, Xuan Xu and others stopped and looked at Xuan Qing who called out to them.

"Junior sister?"

Xuan Qing looked at the few people and said, "I thought we didn't need to rush to Nuanyun Valley."

"Aren't you going to Nuanyun Valley?"

Xuan Xuan stared at the junior sister Xuan Qing who was known as "taciturn and thoughtful" and asked curiously:

"Junior sister, have you made any new discoveries?"

Xuan Qing nodded and shared the information obtained from Yan Xiong with a few people.

Hearing this, Xuan Xuan's heart moved and he looked at Xuan Qing, "Junior Sister, are you talking about...that Foundation Building Pill?"

Xuan Qing nodded and said:

"I guess that the Foundation Building Pill that Pharmacist Zhou gave to Yan Xiong most likely came from the Hexin Tower auction.

As far as I know, before Yan Xiong obtained this Foundation Establishment Pill, there were not too many Foundation Establishment Pills taken from Hexin Tower."

Xuanzhi said: "Definitely yes!"

Xuan Qing shook his head and smiled:

"As long as there is no confirmation, it is better not to be too absolute. What if it leaked from somewhere else? ... However, it is not difficult to verify this."

With that said, Xuan Qing found the current owner of Hexin Tower from the crowd and asked: "Does the Foundation Establishment Pill taken from Hexin Tower have any special markings?"

Host Hexin nodded and said:

"Yes, in fact, in the eyes of professional appraisers, every Foundation Establishment Pill is different.

Every Foundation Establishment Pill sold from We He Xin Lou has detailed identification information records.

With the help of this information, we can easily trace the source of a Foundation Establishment Pill."

Xuan Qing nodded, but continued to ask: "But what if we just look back at the time image restored by the circular light array?"

The host of Hexin hesitated and said: "This... only through color and appearance..."

Xuan Min, the master of the alchemy palace next to him, asked Yan Xiong: "After you obtained this foundation-building elixir, have you ever taken it out and looked at it in a well-lit place?"

Under normal circumstances, the Foundation Establishment Pill will of course stay in the jade bottle.

Inside the corked jade bottle, there was darkness.

This darkness will not become brighter by going back in time.

And it is impossible for them to shine light from now on and illuminate the darkness in the little jade bottle more than ten years ago.

In order to prevent the elixir from leaking out and avoiding the loss of efficacy, the elixir was never taken out from the time it was obtained to the time it was swallowed. Even when taking it, it was just to uncork the bottle and pour it directly into the mouth, from beginning to end.

It has never been exposed, which is possible.

Yan Xiong obviously thought of this, so when faced with Xuan Min's inquiry, he hesitated.

But under the calm gaze of a pair of eyes, he still chose to tell the truth and nodded:

"The association later took a Foundation Establishment Pill from Hexin Building and handed it to me. At that time, I couldn't help but take out both Foundation Establishment Pills and look at them."

Then, the group went to the place where Yan Xiong stayed at that time.

On the way, everyone else was thinking about other things, but Du He, who was full of "evil energy", came to Yan Xiong's side and muttered:
To be continued...
