After a while in the tree hole, Chen Yu suddenly heard a strange sound, sometimes like the soft and coquettish sound of a girl, sometimes like the majestic scolding of an old man, sometimes like the random scream of a madman.

Chen Yu slowly stretched out his head, and saw the mysterious immortal cultivator standing up from the bed, looking at the West with a gloomy expression.

Chen Yu knew that the West was a cliff with rugged rocks on it, and the rocks were abrupt, and it was steep and difficult to climb.

Chen Yu wanted to climb up several times, but after thinking about it carefully, he finally gave up.

At this time, the mysterious immortal cultivator looked at the West with a serious expression. Chen Yu didn't have to think that something strange happened on the other side of the cliff.

These strange sounds seem to have a strange magic, making people's heart beat faster.

You should know that cultivators who have completed the Transcendent Realm can control their five internal organs to a certain extent.

"Go into the tree hole and cover your ears!" The mysterious immortal cultivator shouted sternly.

Chen Yu trembled, closing the door covering the tree hole, covering his ears with one hand and touching the back of his head with the other.

"Shuling, what the hell does this sound come from?"

"I don't know." Shu Ling answered quickly this time.

Chen Yu's heart thumped, which showed that with his level of experience, he could not pose any threat to the owner of this voice.

Chen Yu covered his ears, so this kind of thing should be worrying about the mysterious cultivators outside!

After all, before the mysterious immortal cultivator showed his fangs, the mysterious immortal cultivator was extremely concerned about Chen Yu's safety issues!

Early the next morning, Chen Yu left the state of cultivation. After leaving the tree hole, he saw the mysterious cultivator's face turned ashen and his stiff muscles were beating.

"I like singing and dancing..." Chen Yu deliberately hummed a tune and passed by the mysterious immortal cultivator without looking sideways.

When the mysterious immortal cultivator saw that the boy did not mean asking about the mysterious voice last night, his face became even worse.

When Chen Yu turned to him, the mysterious immortal cultivator returned to his expressionless face and said in a caring tone: "Don't go there in the west. When I encounter danger, I may not have time to save you!"

Chen Yu immediately showed a grateful look when he heard this: "Thank you for your reminder. But Senior, what did you mean by yesterday's voice? I didn't sleep well last night."

"I don't know that thing. There is something in the west that blocks my spiritual consciousness. You just need not go to that place!" said the mysterious immortal cultivator.

Chen Yu left, and he felt a little uncomfortable with the mysterious cultivator.

After getting along these few days, from the small details of life, Chen Yu can almost confirm that this mysterious immortal cultivator has ill-behaved in him.

And the most likely possibility is that this person wants to use him to refine his soul!

Because soul refining requires the person who casts the spirit and spirit, and those who are injured on their bodies must not use this technique.

The incident of hunting wild wolves made Chen Yu realize that he had extremely insufficient combat experience, so he went north to find an open space to practice some boxing and hammering techniques deduced by the book spirit, which also considered it to be a practice.

Practicing hammering techniques and boxing techniques help the body absorb spiritual power. The perfect practice of the Heqi realm is not enough to meditate every day.

But the boxing and hammering techniques that Shu Ling deduced now are mostly talkative on paper, and they are like this.

After all, with Chen Yu's knowledge, it is really not easy to deduce the methods of combat.

The days of practice pass quickly, and in a blink of an eye, another five days passed.

During these five days, that sound would appear every night, and every second day the mysterious immortal cultivator's face turned even more pale.

The progress of the mysterious cultivator's healing was as if it was greatly delayed because of the appearance of this sound!

This made Chen Yu feel quite strange. This strange sound could only make his heart beat faster. Why did it have such a great impact on the mysterious immortal cultivator?

But this is a good thing for Chen Yu!

As this sound frequently appeared, Shu Ling also deduced some of the sound.

"Master, the master of this voice is very strange. I cannot determine its identity." This is the conclusion reached by the Book Spirit.

A few days later, Shuling told him that the method of concealing had been deduced.

Chen Yu studied it for an afternoon and finally got the method of concealment, but he did not dare to use it easily.

The concealment derived from this deduction still has many flaws. For example, although it can hide the sound, it can only block the detection of the spiritual consciousness. If the enemy is in front of you, it still cannot escape.

But it is enough for Chen Yu.

Chen Yu was about to wait until tomorrow, so he took the opportunity to go down the mountain on the grounds of going to the south to fetch water, and from then on he was submerged in the vast sea of ​​people.

But at midnight, Chen Yu heard some movement outside and looked out through the gaps in the door curtain.

The strange sounds remained. During these days, the green mountains at night seemed to be full of these strange sounds, and there were no more cicadas and wolf howls before.

Outside the gap, the mysterious immortal cultivator had already sorted out his clothes and held the flying sword tightly in his hand.

The mysterious immortal cultivator glanced at the tree hole, then moved his body and quietly left the courtyard.

Chen Yu first used the hidden method, then quietly left the tree hole and peeked into the yard of the mysterious cultivator.

The mysterious cultivator's back is tall, and his shadow is pulled long under the moonlight.

He was walking towards the west, his steps were a little heavy and hesitant.

Chen Yu thought for a while, maintained the hidden magic trick, quietly went back to the tree hole and took a dozen talismans, and followed the footprints of the mysterious immortal cultivator slowly.

The mysterious immortal cultivator was not fast, and Chen Yu kept his patience behind him. He wanted to see what the mysterious immortal cultivator was going to do!

Finally, I reached the cliff, and the mysterious immortal cultivator sighed at the foot of the mountain, and the strange sound seemed to be even more chaotic and even louder.

Chen Yu saw the mysterious immortal cultivator rising up with his sword, and his whole body turned into a sword light, and flew back and forth twice in front of the cliff.

Finally, he stopped in the middle of the cliff. It turned out that there was a small platform in the middle of the cliff. This platform was man-made, with clear edges and angularities everywhere, and the bottom was quite flat.

Behind the platform is a deep cave, and the chaotic sound comes from the cave.

The mysterious immortal cultivator hesitated for a while, and finally gritted his teeth and rushed in with his flying sword.

When Chen Yu saw the mysterious immortal cultivator's aura disappear, he immediately stopped hesitating and climbed up the cliff.

This cliff is difficult for mortals to climb, but it is a trivial matter for monks.

Chen Yu guessed that it took less than two minutes before he climbed onto the platform at the waist of the cliff.

Standing on this platform, the messy and strange sound became louder and louder, and the switching speeds were also much faster.

Chen Yu's heartbeats faster.

Touching the back of his head, "Can you see anything in this place?"

"The source of the sound may be terrifying, so retreat quickly!" Shu Ling responded quickly.

Chen Yu's face was startled, and when he turned around and wanted to leave the platform and return, he heard a loud sound.

Chen Yu's heartbeat suddenly stopped for a moment, and he thought that the mysterious immortal cultivator had come out, and in an instant, all the dead souls emerged.

When I looked back, the flying sword was lying straight in the center of the platform. The sword body had lost its light, like a golden iron sword weapon in the mortal world, no longer as sharp as before.

Chen Yu was stunned for a while, and then he saw a long gown throwing out from the entrance of the cave, which was covered with some soil.

"The clothes of the mysterious cultivator!" Chen Yu was so shocked that he almost blurted out.

What kind of existence is in this strange cave!
Chapter completed!
