One more person didn't help Zhan Chen's exploration, they still hadn't found a way out, they were still struggling to explore the underground like a labyrinth.

At this moment, there were bursts of strange sounds like ghosts crying wolves around him, which made Zhan Chen feel like a great enemy, Xu Liyan saw his strange appearance and asked, "Zhan Chen, what's wrong with you?"

"What's the matter? Don't you see that the strange screams in this cave attack people's souls. Zhan Chen was very surprised why Xu Liyan asked him like this.

"No, I don't think it's just the sound of the wind. Xu Liyan was surprised.

Zhan Chen said: "Impossible, I can obviously affect people's minds when I listen to this strange sound, and I went crazy because of it when I first met it, how could you be fine?"

"Is that really the case?" Xu Liyan thoughtfully said.

"Yes. ”

"Oh, I see why I'm unaffected!" she cried out suddenly.

Zhan Chen couldn't help asking, "Why is this?"

Xu Liyan pointed to a ruby necklace around her neck and said, "Probably because I have its protection, this is the blood chalcedony jade necklace that my father gave me, wearing it on my body can have the effect of calming my mind and resisting soul attacks, so this strange voice can't hurt me at all!"

Zhan Chen looked at the necklace around her neck, showing a look of admiration, and said, "Sure enough, it's the eldest lady, there are all kinds of treasures, like I can only rely on my soul power to resist soul attacks." ”

Xu Liyan pouted and said, "Don't talk about the eldest lady and the eldest lady, otherwise I will be in a hurry with you!"

Zhan Chen couldn't help but show a smile and said, "Okay, okay, I'll call you Xu Daoyou." ”

At this time, the strange sound came from far and near, and Zhan Chen hurriedly corrected his color, guarded his mind, and resisted with all his might.

Seeing his serious face, Xu Liyan wanted to take off her necklace and said, "Zhan Chen, otherwise, I'll bring you the necklace." ”

Zhan Chen replied: "No need, I can handle it, and what does a big man look like wearing a red necklace?"

"Don't hold on, by the way, I still have a jade pendant here, which can also have this effect, otherwise, I'll give it to you." Xu Liyan quickly took out an emerald jade pendant from her storage ring.

Zhan Chen squinted at her, and secretly thought: "This eldest lady is really full of treasures, no wonder you want a Xu Zhong to guard by her side all the time, this is to go out alone to break into the immortal cultivation world, and she will definitely be slaughtered as a fat sheep." ”

However, he said: "Thank you Xu Daoyou, even if I borrow this jade pendant from you, I will return it to you immediately." ”

Xu Liyan waved her hand and said, "It's just a jade pendant, I'll give it to you, you don't have to pay it back, anyway, my father and my mother will have whatever they want." ”

Zhan Chen smiled again, took the jade pendant, not to mention, as soon as the jade pendant was in his hands, he immediately felt refreshed, all the evil miasma in the outside world was excluded, and he no longer had to spend soul power to resist the invasion of strange sounds, so he said to Xu Liyan gratefully: "Xu Daoyou, thank you so much, but no matter what, I don't want to covet other people's things, especially such a heavy treasure, if you leave here, I will definitely return it to you." ”

"You don't look like a man, mother-in-law, mother-in-law, I said I'll send you. ”

"This is my principle of being a man, everything must be obtained by my own efforts. Zhan Chen said seriously.

With the protection of the jade pendant, Zhan Chen's pressure suddenly decreased, and his mind became clearer, thinking: "The scope of this ice cave is simply too large, and it is surrounded by such ice walls that can confuse people, ordinary monks enter it, not to mention finding a way out, they will go crazy if they stay for a long time." Only the strong with a strong soul and a strong heart can survive here. There is another point, Guanghong Zhenren definitely has some hints left, otherwise no matter how high the cultivation is, people will not be able to get out of here, but what is this hint?"

Just as Zhan Chen was in a daze, the bewildering strange sound came again, and he suddenly woke up and shouted: "By the way, how could I not have thought of it!"

Xu Liyan on the side saw him so excited, and hurriedly asked with concern: "Zhan Chen, what's wrong with you?"

Zhan Chen's eyes flashed brightly, and he said, "Xu Daoyou, maybe I have grasped the key to leaving here." ”

"Really, great!" Xu Liyan was also very excited, she had had enough of this weird and lifeless place.

Zhan Chen thought for a while, and then said, "But don't be too happy, it's just a guess of mine." ”

"Oh, don't sell it anymore, tell me. ”

"Xu Daoyou, there is only one thing in this cave that can show us the direction. ”

"What is it?"

"That's the sound, don't you see? Within this labyrinth, the only thing that's directional is the sound. ”

"Really?" Xu Liyan listened carefully, but shook her head and said, "No, I can't hear it, I don't know where the voice came from." ”

Zhan Chen fell into a short thought, he knew that there were countless obstacles in this space, all of which could cause refraction of sounds, and even the Yuan Shen Realm and even some of the Enlightened Ancestors were extremely difficult to identify the source of the strange sounds.

However, his situation is special, after he broke through the realm of power and sainthood, he obtained the supernatural power "Di Ting", not only can hear extremely distant and extremely subtle sounds, but also can distinguish the difference between different sounds, even if this difference is small.

Just now, I discovered through listening to the supernatural power that there is actually only one sound source of strange sounds, and it is precisely because there is only one sound source that this feeling of coming from far to near will occur.

Zhan Chen came back to his senses and saw that Xu Liyan was still looking at him intently, her beautiful eyes were full of curiosity, so she asked, "Xu Daoyou, do you believe me?"

Xu Liyan replied: "Then do you still need to ask? I have no choice but to count on you." ”

"Well, you'll follow me later, and I'll try to figure out my way. ”

"Good. ”

"But I have a request. ”

"What requirements?"

"Don't talk to me while I'm listening, that will affect my judgment. ”

"Okay. ”

"Now you just stop talking. ”

Xu Liyan really didn't say a word when he heard him, while Zhan Chen pricked up his ears and listened quietly, and after a while, he suddenly shouted: "Follow me!"

Xu Liyan didn't know what to do, but she immediately followed him.

The two of them went one after the other, winding in the zigzag cave, and advanced for a long distance, but the good times did not last long, and at this moment, the strange sound came to an abrupt end, and Zhan Chen and Xu Liyan had to stop searching.

Xu Liyan asked, "Zhan Chen, what should we do next?"

Zhan Chen thought for a moment and said, "Let's rest here and wait for that strange sound to appear again." ”

"Do you have to wait?" asked Xu Liyan with a frown.

"Yes, and that's all we can do, if we move casually, maybe we will only get farther and farther away from the goal. ”

"Alright then, I'll listen to you. ”

For a long time, Zhan Chen and Xu Liyan were both walking and stopping like this, and strange sounds did not appear very often, sometimes they stopped for a day or two, and the time for playing was also very short.

The rest of the time, Zhan Chen and Xu Liyan could only spend the time in torment and waiting, watching the time pass day by day, both of them had a sense of urgency.
