Since it was the northern region, the sky darkened quickly, but it was not as exaggerated as Yan Xiao's guess of four hours.

In just three hours, it was completely dark.

Ning Yuan gave Yan Xiao a look, and the two left tea money on the table, and slowly walked out of the teahouse.

Yan Xiao followed behind Ning Yuan all the way. Although it was dark, the people on the street had not completely dispersed, and along the way, Yan Xiao noticed many divine senses sweeping over her body.

Long before they came out of Yaoguang, the two of them changed the Taoist robes on their bodies to ordinary Taoist robes.

Yan Xiao was now wearing a pale yellow robe, while Ning Yuan was white that had not changed for thousands of years. The cultivation of the two of them, one was pressed on the tenth layer of qi refining, and the other was pressed on the ninth layer of qi refining.

In the eyes of outsiders, the two of them were just two inconspicuous ordinary Qi refining cultivators.

Several divine senses just swept over the two of them and moved away.

The two who are not concerned are even more convenient to act. Ning Yuan's posture was obviously that he had been to Qulan City, and he saw him shuttling through the streets with a smile on his face, and soon came to an inconspicuous alley.

There were only Ning Yuan and Yan Xiao in the alley, which seemed a little quiet and desolate, but it was a quiet place outside the lively street market.

Yan Xiao watched Ning Yuan release his divine sense to investigate, as if no one was approaching here in all directions, so he walked quickly inside.

After walking for about dozens of feet, Ning Yuan turned his head and glanced at Yan Xiao, "You help me pay attention to the movements around me." ”

Seeing this, Yan Xiao raised his eyebrows, and he responded. Then, she watched Ning Yuan knocking on the wall on the left, beating about half a cup of tea, he seemed to have made a discovery, and then saw a small ice ridge appear in his hand.

The ice ridge was held by Ning Yuan, and at a tricky angle, it pierced into the wall. Then, Ning Yuan quickly retreated from the front of the wall and took two steps back.

With the insertion of the ice edge, the wall began to tremble slightly, and then, the trembling movement became bigger and bigger, Yan Xiao was startled, and his divine sense quickly spread, and he didn't dare to let go of the slightest wind and grass.

Soon, the wall was centered on the ice edge, as if an irregular circular hole with a diameter of about half a zhang had been chiseled.

Yan Xiao glanced at Ning Yuan again, only to see him nodding at Yan Xiao as usual, and motioning for her to go in first.

Seeing this, Yan Xiao didn't refuse, the entrance of the cave was a little small, she got into the cave with some difficulty, and walked into a secret passage.

This secret passage is not like the dark passage that Yan Xiao walked with Cheng Yi before, which requires a cat's waist to pass through all the time.

Although the entrance to the cave is a little smaller, this dark passage is quite spacious.

Yan Xiao took two steps forward, and saw that Ning Yuan had also come in. He turned around and pointed to the hole, and saw that the hole, about half a foot in diameter, was closing at a speed visible to the naked eye.

Soon, it was restored to a complete wall.

Yan Xiao had never seen this kind of technique, and while secretly claiming to be surprised in her heart, she was also a little puzzled, Ning Yuan brought her here, wouldn't it be to find the ice cave.

Before Yan Xiao's mind could turn around, he heard Ning Yuan snap his fingers again, but in an instant, the candles on both sides of the entire passage lit up one after another.

"This leads to the ice cave?" Yan Xiao finally couldn't help it, staring at Ning Yuan who was walking in front and questioned.

"Well, that's all there is to it. But I'm afraid I'll have to walk for more than half an hour. Ning Yuan bowed slightly, "Don't worry, this passage is very safe." ”

Yan Xiao frowned, "It's just why is this ice cave so mysterious?" The direction of this passage seems to be the direction that leads to the center of Qulan City. ”

The center of Qulan City is the location of the Qulan City City Lord's Mansion, that high-level monk is not like the location close to the city gate, there are more low-level monks, it is said that the Qulan City Lord is a monk who has just advanced to the Yuan Infant, and his guards are mostly Jiedan monks. Although they were walking underground at this time, they walked under the feet of others, and with the keen divine sense of the high-ranking monks, they could still detect the whereabouts of the two, so they couldn't help but smile and not worry.

"This is indeed the direction leading to the City Lord's Mansion." Ning Yuan's voice was still as undulating as ever, "That ice cave was built by the Qulan City Lord when he was practicing in his early years, and it had a miraculous effect on the monks of the Ice Spirit Root. ”

The calm voice was waveless, but what he said was something that surprised Yan Xiao.

The ice cave built by the main owner of Qulan City? Ning Yuan actually hit the idea on the city lord's private ice cave?

"The Qulan City Lord is in retreat, and his guards usually don't approach the ice cave, so it's safe there." Ning Yuan seemed to sense Yan Xiao's shock, he turned his head to look at her, and then added this sentence.

Yan Xiao was startled for a moment, and then returned to normal. She knew that Ning Yuan rarely did things that he was not sure of, and if it was not safe here, or if he was not sure that he would leave with his whole body, he would not bring her here.

It's just ...... "How do you know so much about this?" ”

"I used to be here for a year when I was seriously injured." Ning Yuan picked the corners of his mouth where Yan Xiao didn't see it, and spit out this sentence lightly.

"Did you slip in through this secret passage then?" Yan Xiao tilted his head, as if he was a little curious about Ning Yuan in the past.

Ning Yuan nodded, "Yes." I was being hunted down, and someone rescued me, took me into this secret passage, and stuffed me here. ”

Yan Xiao looked at the spacious secret passage here, the edge of the road in all directions, the candlesticks on both sides, and the flat ground were obviously dug by hand and repaired.

This secret passage was obviously deliberately dug out by someone, and the ingenuity outside was also very ingenious.

"Well, I don't know who dug the secret passage here, and the person who can find the secret passage here is also a clever person."

Ning Yuan saw a look of amazement and admiration on his face, and a slight smile appeared on his face, "The person who stuffed me here back then was your master. ”

"My master?" Yan Xiao was stunned, and then showed a look of understanding. Her master, like Ning Yuan, mutated the ice spirit root at the same time, so it would not be strange if it was her master who discovered the ice cave here first.

"It is said that this secret passage was dug by the former city lord of Qulan City, and it originally led to the back mountain of the city lord's mansion. In this, there is also a romantic affair involved. Ning Yuan's eyes were dyed with a smile, but his complexion was a little flushed because of the candlelight or other reasons.

"What a flirtatious affair?" Although Yan Xiao is a monk, he once lived in the 21st century, an era of no gossip and no joy, and he was quite interested in this kind of affair at this time. She didn't know what else the monk could do.

"It is said that the master of the former Qulan City Lord seems to have been injured by a woman, and he is very disgusted with emotions, and he is even more disgusted with female cultivators. The former Qulan City Lord was brought up by him since he was a child, and because of his master's teachings, he was also insensitive to the female cultivators. There has never been a female cultivator around. ”

"But for some reason, one day, the city lord of Qulan, who had been out for many years, actually brought a female cultivator back, saying that she had formed a double cultivator. His master was so angry that he beat the nun out on the spot. ”

"Qulan City Lord is filial piety in the end, and he has no intention of disobeying the master again, and he has cut off contact with that female cultivator on the surface."

Yan Xiao listened with relish, and when she heard that there was anything she couldn't guess here, she immediately asked, "So the Qulan City Lord secretly let people dig this secret passage?" A secret meeting with his monks? ”

Ning Yuan nodded with a smile.

"His master is the previous Qulan City Lord?"

Ning Yuan nodded again.

"At that time, his master was only afraid that he was still living in the city lord's mansion of Qulan City, and he was able to escape his master's eyes and ears and secret meeting with the female cultivators?" Yan Xiao felt a little incredulous.

"That's what makes this secret passage so unusual." Ning Yuan smiled and pointed to the top of the two of them's heads, "Can you see anything special about this?" ”

Yan Xiao was reminded by Ning Yuan, and looked carefully at the top of his head.

At the top of the flat secret passage, Yan Xiao originally thought it was just an ordinary earthen wall, but after a closer look, he could find that the dusty earthen wall had a faint flash of light.

"This is ......" Yan Xiao looked at the faintly shining material, and couldn't help but reach out to reach the wall above his head. Some cold and smooth touch ran through her fingertips, a strange sensation that flowed down her fingertips into her meridians.

Yan Xiao was startled, and quickly withdrew his hand, and put the finger that had just touched the wall under the tip of his nose to examine it carefully, but he didn't find anything wrong.

She raised her head, only to find that Ning Yuan, who she thought was waiting by her side, had walked three feet away from her at some point, and looked back at her with a playful smile, but she didn't even notice it at all.

"This ......" Yan Xiao looked at her fingertips, and then at the earthen wall above her head, her eyes a little excited. Is this material capable of blocking the monk's consciousness? ”

Ning Yuan nodded. After Yan Xiao saw that he acquiesced, his eyes looked at the earthen wall above his head, and they became a little fanatical.

"But don't think about it, this thing, I've tried, but I can't dig it up." Ning Yuan first stared at her, watching her stupidly laugh for a long time, and finally when she was about to take out the tools from the Qiankun bag and try it, he suddenly poured a basin of cold water on her.

In other words, this is an alluring mountain of gold, but they can only look at it, but they can't take it away. It's not even possible to take a small piece away.

Yan Xiao suddenly lost interest in it, no matter how good things are, they won't be yours if they keep looking at it.

Since she couldn't take it away, Yan Xiao didn't force it, she glanced at the wall above her head with some reluctance, and then followed Ning Yuan's side again without squinting and walked forward.

"No wonder you are so relieved about this passage, with this kind of thing here, those Yuanying Cultivators, it's really not easy to find us."

Ning Yuan nodded and said with a smile: "The former city lord of Naqu Blue City is really willing to give up his blood for his fellow Daoists. ”

Yan Xiao couldn't help but smile when he heard this, and sighed: "I didn't expect there to be such a ...... among the monks."

Ning Yuan glanced at Yan Xiao, as if he was wondering why Yan Xiao didn't finish his words. Yan Xiao received Ning Yuan's gaze, but only shook his head, "I don't know how to describe it, whether this is love or something else." ”

Ning Yuan glanced at her again, but then he didn't express any more opinions at this time.

"You say, now this Qulan City City Lord knows this secret passage?" Yan Xiao also tilted his head and asked with some curiosity.

Ning Yuan shook his head, "I don't think he knows, otherwise he wouldn't have built the ice cave in this location and was used by us as a public healing room." ”

Yan Xiao thought about it for a while, and asked herself if she knew that there was a secret passage behind her cave, and that others knew how to get in, then she would probably block it, or simply move the cave to a place.

"Just, how did you know about that affair?" If even the current Qulan City Lord didn't know about the existence of this secret passage, presumably the previous affair must not have been widely circulated in Qulan City.

"This ...... I'm going to go back and ask your master. This time, Ning Yuan sold another pass, which made Yan Xiao roll her eyes involuntarily.

The passage was a downward sloping passage, and the two of them walked for about half an hour before they began to fall silent.

Although the material on the top of the head of this secret passage can block the monk's divine sense, who knows if those high-level monks have any great opportunity to detect their existence through this material, so the two of them are still more cautious, try to restrain their breath, and do not make any sound.

After walking forward for another quarter of an hour, Yan Xiao and Ning Yuan finally saw the end of the secret passage.

This end is very spacious, stepping through a small door, Yan Xiao was shocked to realize that it was really different.

Although this is the end of the secret passage, it is a spacious stone chamber. Desks, beds, alchemy furnaces...... It's not much different from an ordinary cave house.

"This ...... It's really like a place for secret meetings. ”

Who would have thought that a beautiful city lord would not live in the luxurious cave of the city lord's mansion, and he would come to the ground and dig a basement, but it was not for the sake of the golden house.

Ning Yuan still chewed a smile on the corner of his mouth, but Yan Xiao tilted his head and shook his eyes.

Ning Yuan's facial features are indeed the best among male cultivators, and he doesn't think it's anything if he doesn't smile on weekdays, but this smile makes Yan Xiao feel that the thousands of miles of ice have been thawed.

"No wonder Senior Brother Ning doesn't smile often on weekdays." Yan Xiao couldn't help it, so he muttered, and was listened to by Ning Yuan.

"How?" He was a little curious, raised his eyebrows, and looked at Yan Xiao with a smile still on his face.

"If you laugh a lot, the ice has melted, how can you cultivate?" A joke was originally used by Yan Xiao to tease Ning Yuan, but after Ning Yuan heard it, he couldn't help it and bent the corners of his eyes.

Under the rare joke between the two, Ning Yuan stepped forward and began to bang again against an empty wall.

However, Yan Xiao saw the Xiaoice ridge of the same shape in the alley before appearing in Ning Yuan's hand, piercing into the wall in a strange arc. (To be continued.) )
