Lin Yan looked straight ahead, as if he wanted to see through the front at a glance, and whispered, "Is your mother's unison card in front?"

Yu Xiyun nodded with a serious expression, then took the Tongsheng card in his hand and looked forward with his eyes.

"Let's go, then we're not far from our destination, and for now we'd better find the bones of the flooded Sands and your mother as soon as possible, and find a way out of this place. Lin Yan immediately walked forward.

Yu Xiyun glanced at Lin Yan, and then nodded slightly.

Then the two continued to walk in this direction, and nothing happened along the way, but the atmosphere was too quiet, so that the two did not dare to take it lightly, after all, any strange thing that appeared in it was so normal.

"Well, after a little walk, you should be able to see the underground cave that your father talked about. Lin Yan whispered as he walked.

"It should be. Yu Xiyun frowned slightly, kept looking ahead, and then asked with a hint of confusion in his tone: "I don't know why, I always feel very uneasy in my heart." ”

Lin Yan shook his head, indicating that he was also a little uneasy in his heart.

"Let's go. Lin Yan then spoke.

After another half a pillar of incense, Lin Yan and the others walked to the end of this direction, and at the end was a towering cliff. The cliff above was shrouded in layers of black mist, and even if Lin Yan and the others used that kind of tears, they couldn't see it clearly.

"It seems that we have come to the end, but where is the cave mentioned in your father's diary?" Lin Yan walked in front of the cliff, his right hand gently caressing the protruding rock above, and a cold chill passed through.

Yu Xiyun's eyes also flashed.

At this moment, the light on the Tongsheng card in her hand suddenly bloomed, and at the same time, the jade card slowly levitated from Yu Xiyun's hand, as if it wanted to fly upward.

Lin Yan and Yu Xiyun's eyes froze slightly, a gleam flashed in their eyes, and at the same time, their eyes fell on the jade plaque.

"What's going on here?"

"It's a peer card inducting each other, and if I'm not mistaken, my mother's bones should be on top of it. Yu Xiyun's eyes showed a strange color.

"What do you mean?" Lin Yan's eyes narrowed slightly, and his gaze looked at the cliff covered by black mist.

"It was on this cliff. Lin Yan asked and answered himself.

The two glanced at each other, and immediately their figures flashed, flying upward, and the black mist composed of black insects came to harass them as always, but it was not too much trouble for them.

When the two of them flew hundreds of meters, their eyes seemed to fall on the cliff through the black mist.

"This should be it. Yu Xiyun glanced at Lin Yan and said lightly. Because at this time, the Tongsheng card in her hand had already snorted, broke free of her right hand, and flew forward.

The two of them stared slightly, and followed closely.

"Sure enough, there was a cave. ”

The two of them came to the edge of the cliff, and sure enough, they found that there was an exit on it. Without the slightest hesitation, they flew inside.

Having entered the entrance of the cave, the two of them landed one after another, and slowly walked in with nervous expressions. Although the entrance to the cave is a little narrow, the inside is very wide and does not look crowded at all.

After the Tongsheng brand flew into Shandong, it did not stay, and flew straight inside. Obviously, another Tongsheng card is still in the more.

The two looked at each other and immediately followed.

............

"Well, there are two skeletons in front. Lin Yan's eyes froze slightly, and he stopped.

When Yu Xiyun heard this, his eyes also looked over, and then his expression changed slightly, and a gloomy look appeared on his face.

Lin Yan's attention fell on the two skeletons, but he didn't notice the change in her expression.

Lin Yan stepped forward, half-crouching, only to see two bones facing forward and feet facing back, and both skeletons were covered with cracks, as if they had been attacked by blunt objects before their deaths. Then he narrowed his eyes, stretched out a finger and dipped it on the ground next to the bone, then took it to the tip of his nose and sniffed it, and then he did the same again near the bone.

"It's ...... It seems that it was not a blunt object attack, but other reasons, otherwise it would not have been possible to have such a large area of ~ blood. Lin Yan's face sank slightly, since he trained into a zombie body, he has an unusual sensitivity to blood, if he didn't guess wrong, there is still a faint smell of blood left in this soil, but this smell of blood is very thin, ordinary people can't notice it at all.

Looking at the posture of the two skeletons, it seems to be fleeing, but it doesn't seem to have escaped. Lin Yan showed a solemn look in his eyes, and the cracks on his bones were like spider webs, which couldn't help but make his heart sink from the bottom of his heart, what kind of situation did these two people suffer before they died, so that they would become like this.

"Magic bats, I didn't think they even existed. At this time, Yu Xiyun also followed, and a haze appeared in his eyes.

Lin Yan's expression changed slightly, and he turned his head to look at Yu Xiyun behind him, his eyelids sank.

Yu Xiyun felt Lin Yan's gaze, her expression flickered, and then she said with a smile: "I also saw this from an ancient book. ”

A smile appeared on the corner of Lin Yan's mouth, and he asked in a low voice, "How can you be sure of the magic sound bat in your mouth?"

"As mentioned in the ancient book, this magic bat can emit a sound wave that causes the blood in the living organism to resonate, producing a strong vibration that is enough to shatter the whole body of the creature, just as you see in front of you, the bones of the whole body shatter. Yu Xiyun spit out, and then said with an ugly expression: "And this sound wave is extremely weird, and there is no way to defend against it, unless you desperately use your cultivation to suppress the blood vibration." ”

Lin Yan's face also changed, and then his eyes narrowed, and he glanced at the two skeletons under him again, and said with a gloomy expression: "That magic sound bat seems to be a little bit inside." ”

Yu Xiyun nodded.

"Then what should we do now?" Lin Yan frowned and looked at Yu Xiyun beside him.

Yu Xiyun's expression narrowed slightly, and a smile appeared on her beautiful face: "I have two pills here, which can make our blood flow almost stop, although it can't completely stop the impact of that sound wave, but at least it can delay the time of the attack." Then she took out two bright red pills the size of her thumb.

Lin Yan narrowed slightly, looked at the two pills in her hand, didn't say anything, just took it with a calm face, and swallowed it in one gulp.

This man...... Problematic!

Yu Xiyun also took it down.

Then Yu Xiyun looked at Lin Yan with a smile in his eyes, and said softly, "Let's go." ”

Lin Yan nodded, this elixir was really as she said, the flow of his blood began to slow down, as for whether it could delay the attack as she said Lin Yan didn't know, but now he was about to find the flooded golden sand, so he would never be able to give up easily.

"These two must be two of the monks, but unfortunately it seems that there are no storage bags or rings for them, and they must have been lost. Lin Yan's tone carried a hint of regret.

Yu Xiyun on the side smiled indifferently.

Then the two of them walked inside again, and after a while, they saw a hole, and Lin Yan's eyes narrowed slightly, because there was a Tongsheng card floating in the inside of the hole.

Yu Xiyun looked at it, and a flash of joy flashed on her face, but then sadness appeared on her face.

"It seems that your mother's bones are here?" Lin Yan subconsciously glanced at Yu Xiyun beside him, just at that moment, he seemed to feel the joy of the other party, it was definitely not the emotion that a daughter should have when she saw her mother's bones.

"Yes. ”

"Let's go inside. Lin Yan took the lead and walked towards the entrance of the cave inside. But when he stepped into the entrance of the cave, his face changed, his head rose slightly, and he saw that the stone wall above the entrance of the cave was covered with upside-down bats, these bats were slightly different from the bats he usually saw, first of all, they were a little larger, the size of an ordinary human head, and their bodies were covered with white spots, which looked very strange.

Lin Yan's expression was slightly shocked, looking at the bats covered with stone walls, he finally understood why the death of the two monks outside was so miserable, when the monks passed through the black fog, Zhihai was hit hard, and there was no room for escape when they encountered this strange sound wave.

Then Lin Yan's eyes fell on the broken skeleton in the west of the Tongsheng brand, and he saw that there was a gray ring on the thumb of the skeleton.

At this time, Yu Xiyun behind him strode to the skeleton, squatted down, took off the ring, and quickly put it into his own receiving ring.

But in the next moment, Lin Yan's face suddenly changed wildly, because Yu Xiyun's actions had already attracted the attention of the magic sound bat.

The bats above the stone wall suddenly became agitated, and their wings-like wings fluttered and fluttered.

At the same time, a painful look appeared on Lin Yan's face, and he instantly felt that the qi and blood in his body were turning over and over, and the qi and blood were like a huge wave higher than the other, constantly impacting his meridians, as if he wanted to break free from the shackles of his body and spray out.

"Is this the weird sound wave?" Lin Yan's face became more and more difficult to look at.

The sound of the bat easily penetrated the aura shield on his body and entered his body, pulling his qi and blood to stir.

"Hurry up, I can't hold back the surging qi and blood. Lin Yan snorted and spat out a mouthful of blood.

Yu Xiyun on the other side also had an ugly face, and then put away the bones on the ground and prepared to rush inside.

Lin Yan followed behind.

But at this moment, the magic sound bat became even more restless, and fell from the stone wall suddenly, fluttering and fluttering towards the two of them, enveloping them.
