The stone wall was rough, and the weeds and vines were dense on it, and the middle-aged man still knelt on the ground and did not get up after saying that.

After a while, the grass and trees on the stone wall suddenly moved, and as it slowly wriggled and the lines on the stone wall gradually combined into a one-zhang-sized humanoid face outline, from a distance, this human face was extremely realistic, and its facial features were all there.

"Very good...... Go to the Taicang Mountains, that ceratosaurus will be your arm!"

The huge mouth on the stone wall, which was made up of rock lines, moved up and down twice, and a sentence came out of it.

The middle-aged man kneeling on the ground heard Hou Mu Na get up, looked down at the light spots flashing on the compass in his hand and turned to leave, when he left this mountain range, the color of Mu Na on his face disappeared, and returned to a normal human look, but there was always a faint voice in his heart that kept reminding him.

Besides, Lu Yun, at this moment, he was approaching the stone gate at the bottom of Wanyin Pond, and the closer he got here, the more clear the familiar feeling in his heart became.

This stone gate is about a foot high, exactly the same as the stone gate in the cave of the Plum Blossom Master, and there is a hint of coldness when touched by the hand, as if it contains an extremely strong cold power.

Thinking of this, Lu Yun's heart suddenly moved, and he clinged to the edge of the stone gate with both hands, and moved to the side for cultivation.

Suddenly, the stone door moved open in a click, revealing a hole the size of a zhang, and suddenly a cold breath came to his face, but Lu Yun frowned slightly when he felt it carefully.

"This is by no means the power of the extreme yin......"

Just as Lu Yun was feeling, he found that when the pool of water gushed to the entrance of the cave, he couldn't enter the slightest, as if it was blocked by something.

"It looks like it's another formation!"

Lu Yun stopped for a moment and then moved and walked towards the entrance of the cave.

The cave is dark, but Lu Yun's cultivation is now greatly rising, and he can still see everything in it, the stone tables and chairs inside are complete, it seems that it is also a cave, about three zhang in size, and there is also a stone gate in front of the opposite side that is exactly the same as here.

Lu Yun was startled, and there was a faint guess in his heart, and he walked towards the stone gate in front of him between his feet.

When he walked to the middle of the hall, a beam of light suddenly appeared above and shone down, which happened to hit Lu Yun, and Lu Yun was shocked.

Lu Yun, who was irradiated by this beam, found that he seemed to be imprisoned, and he couldn't move at all, and it was impossible to even move his fingers.

Just when Lu Yun was frightened, suddenly a picture appeared out of thin air at the stone gate in front of him, in which there was a middle-aged man in his forties standing in the air, his clothes were blown by the wind, his head was full of silver hair like silk, but his face did not show any old age, he stood in the air like a mountain with a black giant axe in his hand, and slashed at the mountain range below with an axe from top to bottom.

"Heaven is unfair, then don't blame Lao Tzu for beheading your monitoring envoy!"

As his shouts fell, the mountains collapsed and broke into two, one sinking into the ground and the other shaking. Immediately after the picture turned, a huge dragon head with a square circle poked out from under the broken mountain range, and a curved long horn on the head was particularly conspicuous, it seemed to be awakened and suddenly opened its mouth to let out a roar, the roar made the sky and the earth change color, the sky was full of thunder, the clouds were gone, the grass and trees on the ground swayed and undulated, and some even took off to the ground and took off into the air.

Immediately after the dragon opened its mouth of blood and bit the middle-aged man in the air, Lu Yun was shocked, at this moment it bit in the direction of his side, he couldn't help but move his body to avoid it, but found that his body was already imprisoned, and the blood gushed through Lu Yun's body, and then the picture dissipated into nothingness.

Lu Yun came to his senses in an instant, and found that he was still in this cave, and it was just a scene just now. As the picture disappeared, the beam of light that imprisoned Lu Yun also disappeared.

"It's so realistic that I think I'm in it......"

Lu Yun muttered with palpitations, and then his heart moved, thinking of the black giant axe in the hand of the middle-aged man in the picture just now, it seemed to be the enlarged appearance of the top-grade legal Tiangang Cloud Axe conceived in his dantian.

There is also the severed mountain range, one of which looks more and more like the Taicang Mountain Range where Wen Cangmen is now.

The more Lu Yun thought about it, the more frightened he became, and at this moment he already knew in his heart that the middle-aged man who was like a mountain just now was probably the Emperor Cairui body ten thousand years ago, and the black giant axe in his hand was the Tiangang Cloud Axe in his current dantian.

Was that dragon with horns on its head the dragon that the Venerable Plum Blossom had said that attacked the two of them?

Lu Yun guessed in his heart, but he didn't understand why he saw such a picture here.

He stood there and looked around, and then on the left side of the hall, near the corner, he saw a low shelf with a wooden box on it.

He was originally at the door of this cave mansion, and he couldn't see the scene on both sides of the cave hall, but as he approached now, if it weren't for the confinement of the beam of light just now, he still wouldn't have noticed that there were other things on both sides of the hall.

On the right side of the hall was a Taishi chair, on which sat a dry skeleton, and the dry bone was raising a finger to point ahead.

Lu Yun looked in the direction his finger pointed, and it was the wooden box placed on the low shelf opposite.

Seeing this, Lu Yun frowned, and after thinking about it, he couldn't help but be curious, and raised his feet and walked towards the shelf. As soon as Lu Yun's hand touched the wooden box, the wooden box dissipated like light smoke, revealing a white jade slip from inside.

"Jade Jane again?" Lu Yun's heart moved, picked up the jade slip and looked at it for a while, and after finding that there was no abnormality, he immediately put it on his forehead, and after three breaths, Lu Yun took the jade slip off his head.

"Peeling off the cocoon, look at what this jade slip says, this technique is a high-level technique practiced after the problem of the meridians of the Emperor Cairui's body is lifted, and it will be more useful with the yellow silk thread that has been successfully refined in the body?"

Lu Yun thought for a moment in his heart, and put this jade slip into the storage bag, regardless of whether this method was useful or not, at least not now.

When he looked at the dry bones behind him, he was suddenly startled again, only to see that the raised palm of the dry bones before was hanging down at this time, and at the same time, a bottle of pills fell from the chest of the dry bones.

"The bottle of Zengyuan Pill on Wanyin Lake is gone, isn't it here? Could it be that this dry bone is the flesh of the Plum Blossom Master?"

Thinking of this, Lu Yun hurriedly walked to the stone gate that he was about to go to just now, and with a hard push, the stone door opened, revealing a cave hall of the same size outside, which was the real cave mansion that the Plum Blossom Master had taken him down to the ground before.

"If that's the case, these two places are connected, and the Plum Blossom Master entered the stone gate before he came here!"

"Senior Sister Miao must have been hiding here just now, if so, she must have seen the wooden box, why didn't she take it, and the bottle of Zengyuan Pill?"

These questions were fleeting in Lu Yun's mind, and he decided to wait until he saw Miao Sixuan again in three days.

Looking at the bottle of Zengyuan Pill that rolled down on the ground, Lu Yun picked it up and put it in the storage bag, the two places are connected, and the other end must not be able to get out, he carefully looked at the scene in the cave again, and then came to the dry bones and bowed three times with his fists in front of the dry bones.

The Venerable Plum Blossom has been very kind to him, and his only doubt now is that he doesn't know whether the hidden vein in the Tiangang Cloud Axe is complete, and he can only seek opportunities to find the answer slowly in the future.

Lu Yun came to the stone gate and closed the stone gate of the cave again, and the moment he closed the stone door, the dry bones sitting on the Taishi's chair in the cave suddenly dissipated into ashes.

"It's not a trip in vain to get this cocoon peeling technique this time, and the rest can only be said later!"

Lu Yun's body moved, but he swam at the bottom of the pool, and after a while, his figure broke through the water, and after a little tiptoe on the surface of the water, he rushed again to the gap in the dilapidated stone wall above.
